Diabolo...

Image Source: Link below
Topics: Geometry, Mathematics, Optical Physics

A ring-shaped optical cavity has degenerate resonant modes, because clockwise and anticlockwise waves resonate at the same frequencies. The degeneracy can be lifted, and the frequencies split, by a perturbation such as a physical rotation or the presence of a molecule or nanoparticle. Typically, the frequency splitting is proportional to the perturbation’s magnitude, as illustrated in the top panel of the figure for a hypothetical complex-valued perturbation ε (that is, one that can affect both the light’s frequency and its phase). Because the plot’s shape resembles a yo-yo-like toy called a diabolo, the degeneracy has been dubbed a diabolic point. The mode splitting around a diabolic point is the basis for optical gyroscopes, and it’s been explored for other sensing applications.

There’s another type of degeneracy, called an exceptional point, where not only do resonant frequencies coincide but their resonant modes do too. In the case of the ring resonator, inserting reflectors to scatter light from the anticlockwise mode into the clockwise mode (but not vice versa) creates an exceptional point with a single resonant mode, the clockwise-traveling wave. Perturbing the system splits that mode into two resonances, each with a small admixture of the anticlockwise wave, and the frequency splitting scales with the square root of the perturbation magnitude, as shown in the bottom panel.

Exceptional points make for exceptional sensorsAt just the right locations in parameter space, resonant frequencies are ultrasensitive to tiny changes.Johanna L. Miller, Physics Today

Phase II Transitions...

Image Source: An article on LinkedIn by Linda Morales
Topics: Commentary, Education, Nanotechnology, STEM

In the post Transitions, I alluded to I might not be posting as regularly due to the rigors of graduate school. Well that rigor came last week and this week. I'm getting my footing on homework, collaboration and time management. The faculty, staff and student body here are the picture of diversity. I've literally met people from around the globe and not once have I repeated a country on our introductions. Ghana...Korea...Iran...Saudi Arabia...Sudan...Sweden...et al and each when I said I grew up in Winston-Salem (30 minutes west on I-40) and I'm an alumni of the university, they have without fail stated: "you came home."

I re-acclimated myself to the new F.D. Bluford Library. It's much larger with three floors, the top being the quietest place to study in. The librarians said I'd be there a lot, reading the papers my professors published in journals, of which they have a lot of from American, Indian, Chinese journals as well as from professional technical societies if memory serves. The old Bluford was renamed in honor of my Chancellor Edward Fort as a research and grant center. He's still around, and teaching as well as Dr. Casterlow (my karate and calculus instructor - retired) and Dr. Sandin, who's taught at A&T since 1968. He taught Dr. Ron McNair his first physics class, as he had taught mine. After 50 years of honorable and distinguished service, he'll retire next year.

One of the things I got over quickly was being an older graduate student. I saw some during graduate orientation that at least looked distinctly older than me. No one has made me feel uncomfortable, and the chair of the Nanoengineering Department said I wasn't his oldest student (I asked). He graduated a PhD last year at the ripe young age of 63. He's working as a director in industry. There's hope.

I've joined the Nano Energy group as my research area of concentration. I interviewed the principle investigators in that and the nano-wire/photonics group before I made my decision, both areas tempting and equally interesting. I felt energy was a good fit for my industry experience, science and social interests and my inclinations to do something that makes the world a better place.

I also share Dr. Cho's ambition of getting more African Americans into batteries and by extension STEM fields: the New York Times published an article stating even with Affirmative Action, African Americans, Hispanics/Latinos lag behind all other groups since I was an undergrad. I recall 1980 was supposedly the largest number of African American males attending colleges and universities, noted again by the New York Times in a 2002 related article, observing more sadly are inmates. I speculate the impacts of globalization, adolescent pregnancies and inadequate educational resources (see NYT article, second link) keeps societal stratification darkly and remarkably intact.

The JSNN (Joint School of Nanoscience and Nanoengineering) has a "nano-bus" they use to do K-12 outreach. It's a teaching requirement for PhD students (that can also be fulfilled by grading papers or teaching a class or lab), so I volunteered. I was respectfully declined as this is my first semester, and the graduate coordinator wants us to focus on setting a good foundation to be successful. After my fire hose days, I can see the importance. When it's appropriate (i.e., I've successfully managed time and the fire hose), and for reasons I hope I've made you understand, I'll be getting on that bus.

Researchers at Princeton University and the Lawrence Berkeley National Laboratory have succeeded in controlling nuclear spins in silicon by purely electrical means. Until now, electronic or nuclear spins could only be manipulated through radio-frequency magnetic fields. The feat could help in the development of quantum processors based on nuclear spin qubits.

Classical computers store and process information as "bits" that can have one of two logic states ("0" or "1"), but quantum computers work on the principle that a quantum particle (such as an electron or atomic nucleus) can be in two states at the same time – "spin up" or "spin down". These two spin states represent a logical "1") or a "0", so N such particles –or quantum bits (qubits) – could be combined or "entangled" to represent 2N values simultaneously. This would lead to the parallel processing of information on a massive scale not possible with conventional computers.

In practice, it is difficult to make even the simplest quantum computer, however, because these quantum states are fragile and are easily destroyed. They are also difficult to control. For a qubit to work, it should thus be well isolated from its environment to preserve its quantum properties, and prevent "decoherence". At the same time it should be robust enough so that its state can be read out and manipulated. The intrinsic magnetic moment of an atomic core, or nuclear spin, is a good qubit candidate in this respect because it fulfills all of these criteria.

There is a problem, however, in that the magnetic moment of a nuclear spin is 10 billion times smaller than the moment of one bit of a modern hard drive, and it is almost impossible to detect, let alone manipulate, such a tiny signal.

My name is Kenneth James, and I am currently editing the personal journals of the renowned SF writer Samuel R. Delany in a multivolume series for Wesleyan University Press.  The first volume, In Search of Silence -- which collects Delany's journals from the 1960s -- has, since its publication earlier this year, received very positive reviews from such venues as The New Republic, The Gay & Lesbian Review, and the Barnes & Noble column by SF critic Paul Di Filippo.  Here are links to two of these (the G & L Review article is unfortunately behind a paywall):
The next volume, which I'm working on now and which is entitled Autumnal City, collects Delany's personal journals from the '70s -- during which time Delany wrote some of his most groundbreaking work, including Dhalgren, Trouble on Triton, and Tales of Neveryon.  During this time he also did substantial preliminary work for the novel Stars in My Pocket Like Grains of Sand.
I've just launched a crowdfunding campaign at Indiegogo to fund the completion of Autumnal City.  Here is a link to the campaign page; do check it out if you'd like to learn more about the project:

3D Living Tissue...

Scientists at the University of Oxford have developed a new method to 3D-print laboratory- grown cells to form living structures.

The approach could revolutionize regenerative medicine, enabling the production of complex tissues and cartilage that would potentially support, repair or augment diseased and damaged areas of the body.

In research published in the journal Scientific Reports, an interdisciplinary team from the Department of Chemistry and the Department of Physiology, Anatomy and Genetics at Oxford and the Centre for Molecular Medicine at Bristol, demonstrated how a range of human and animal cells can be printed into high-resolution tissue constructs.

Interest in 3D printing living tissues has grown in recent years, but, developing an effective way to use the technology has been difficult, particularly since accurately controlling the position of cells in 3D is hard to do. They often move within printed structures and the soft scaffolding printed to support the cells can collapse on itself. As a result, it remains a challenge to print high-resolution living tissues.

Appomattox Legacy...

Topics: Civics, Civil Rights, Commentary

Today is my 55th birthday. I start graduate classes today. I'd hoped to be in a better mood, an uplift from Friday's post.

Saturday, I watched the events in Charlottesville, Virginia unfold on national television. My wife cried even before the name of the victim run over by a coward was announced. I'm sure her as well as my own thoughts drifted to our adult sons. My nephew opined about his own son, not even a year old and the world he and his girlfriend have to prepare him for.

I'm studying an exciting STEM field (Nanoengineering), but I find the living at my particular artificial societal demarcation of humanity exhausting. No one can convince me this isn't a mental disorder; a mass hysteria born of the first African American being elected president of the republic in 232 years and the backlash encouraged by right/Reich wing web sites, talk radio and schlock television hosts on conservative outlets. Despite having their chaos agent in power, this madness continues unabated.

I will study HARD. I think it's the only thing that will keep me calm...and sane.

I could only think of the post for Appomattox (April 12, 2015). I think it is apropos for our current and continuing neurosis on division, expanded via FOGHORN by our current "chief executive*", an obvious accident of a bereft national knowledge of civics responsibility.

His response to the violence Saturday he encouraged during the campaign was weak and tepid. An obvious dolt at history, he's never heard the quote made famous by Malcolm X "the chickens have come home to roost," (and he wasn't the origin of it, just its more modern proponent) now a double entendre of karma and irony.

One would think he was concerned about how his words would be measured by the Klan and Neo Nazis, and could care less what the rest of his nation thinks.

Thursday, 9 April was the Sesquicentennial, the 150 year anniversary of the South's official surrender to the North in the person of Generals Robert E. Lee to Ulysses S. Grant in Appomattox, Virginia. On the same date in 1947, Branch Rickey signed Jackie Robinson, making him the first African American to play in major league baseball; the first professional athlete of color in any sport at the time. He walked through a door first opened by Jesse Owens at the 1936 Olympic Games, invalidating Hitler's theories of Aryan athletic superiority.

Yesterday, Walter Scott was buried...murdered in the heart of the Confederacy, for a broken tail light.

Cliven Bundy - that $1.1 million dollar, artful, tax-dodging welfare queen, who actually through armed militia threatened US officials with armed insurrection - is still free.

Dred Scott - the man for whom the Supreme Court's most daft decision was the match spark for the Civil War (and apparently, the nomination of Abraham Lincoln as candidate to the-then radical/progressive republican party) - said in the opinion of Chief Justice Taft:

"In the opinion of the court, the legislation and histories of the times, and the language used in the Declaration of Independence, show, that neither the class of persons who had been imported as slaves, nor their descendants, whether they had become free or not, were then acknowledged as a part of the people, nor intended to be included in the general words used in that memorable instrument...They had for more than a century before been regarded as beings of an inferior order, and altogether unfit to associate with the white race, either in social or political relations; and so far inferior, that they had no rights which the white man was bound to respect; and that the negro might justly and lawfully be reduced to slavery for his benefit." [1]

Hauntingly, Dred Scott is buried just miles outside of Ferguson, Missouri.

From a similar, thoughtful article in The Atlantic: "It is easy to proclaim all souls equal in the sight of God,” wrote James Baldwin in 1956 as the Civil Rights Movement took hold in America; “it is hard to make men equal on earth in the sight of men." [2]

Since the election and reelection of President Obama, it's apparent we've never stopped fighting the Civil War. As publicly directed towards him, there is an obvious visceral disdain for the part of the American electorate that he, by existing embodies. There has been since his two terms an increase in highly motivated hate groups; hate crimes; the escalation in murders (example by this recent affront), luckily caught on a citizen's smart phone. Some would say the president has encouraged this. However, I posit that it's not his encouragement, it is his presence in the Presidential Mansion - renamed The White House after a visit to President Theodore Roosevelt by Booker T. Washington, and the national backlash it ensued [3] - that is so offensive to those that don't want their place in the social hierarchy disturbed (wanting "their country back"). From Trayvon Martin, Jordan Davis, Renisha McBride, Eric Garner and now Walter Scott: the Facebook meme below sums up the anger and frustration felt by citizens of this country. [4] It means we can never relax, never just "be." Even our genetic telomere lengths are shorter due to this stress.

Over time, the Civil War became the subject of great romanticization and sentimentalism in cultural memory. For veteran soldiers on both sides, reconciliation required time and the pressure of political imperatives imposed by the larger society on them and on the conflict’s memory. In the wake of this war, Americans faced a profound and all but impossible challenge of achieving two deeply contradictory goals—healing and justice. Healing took generations in many families, if it ever came at all. Justice was fiercely contested. It was not the same proposition for the freedmen and their children as it was for white Southerners, in the wake of their military, economic and psychological defeat. And in America, as much as it sometimes astonishes foreigners, the defeated in this civil war eventually came to control large elements of the event’s meaning, legacies, and policy implications, a reality wracked with irony and driven by the nation’s persistent racism. [2]

Walter Scott sprinted from the scene of a traffic stop, possibly thinking he was to be served for neglected child support payments. That is not worthy of an execution. He was shot in the back with the same regard as cattle at a slaughter shop; killing a mad dog fleeing. Considering that I am a US citizen that trained in a STEM field, an armed forces veteran (as Walter Scott); a MAN: I, nor my sons (the oldest also a veteran) should feel like this in our own country:

The "United" States of America: You cannot be united if you still support the slavery historically-generated "states rights" in everything from voting rights for African Americans; criminalizing a woman's right to choose, to same-sex marriage. The Ku Klux Klan; the John Birch Society; the Tea Party are the typical regressive reactionary responses to any fairness; any progress from the "lesser classes" that should "know their places." [5] We are becoming a byword; an oxymoron. The global economy we encouraged we're falling woefully behind. Technologically backpedaling, we are contesting Darwin and "Creation Science"; anti-vaccination activists to actual scientists; the Jesuit 6,000 year estimate to actual red shift measurement of the age of the universe; climate disruption that the Pentagon sees as an existential threat snowball poo-pooed as pseudo-controversy: our competition abroad has no equivalent analog - our inanity is being ignored for good reason. Like ancient Rome, we're bloated and over-extended; intensely tribal and superstitious; pseudo-scientific; withering from within. We are now a de facto Oligarchy, the only thing we're lacking is the final, deafening crash on the heaps of feudalism and anachronism. We could avoid it by an evolution in thought and policy; a new Appomattox that reinvigorates the republic, and takes this country forward: our viability as a nation is really in the long run, what matters for us all.

Madness and Hiroshimas...

On August 6, 1945, 8.15 am, the uranium atom bomb exploded 580 meters above the city of Hiroshima with a blinding flash, creating a giant fireball and sending surface temperatures to 4,000-C. Fierce heat rays and radiation burst out in every direction, unleashing a high pressure shockwave, vaporizing tens of thousands of people and animals, melting buildings and streetcars, reducing a 400-year-old city to dust. [1]
Topics: Commentary, Existentialism, Politics

"Fire and fury"...that sounds tough until you denigrate 755 career diplomats an adversary expels in a retaliatory move for [them] interfering in our last election cycle. 755 professionals, their families...and children that will be displaced stateside just as schools are starting. It sounds strong, but when Kim Jong Un thinks it's crazy, it likely is. There will be no "cost savings" or reduction to any payroll, as unbeknownst to most of us, Moscow hasn't raised their flag above our capital (yet). It's an obvious dodge, diverting attention from the ongoing Russia investigation, "playing chicken" with extinction for an ego; the plot for a poorly scripted reality show we're all haplessly in.

We cannot continue "government by tweet and bluster." We cannot call ourselves a federal republic when our leader undermines his own citizens. We cannot continue as a nation, a PLANET or a species.

He was aptly described as a "chaos agent" during the primaries. He proves it daily.

The Atomic Bombings of Hiroshima and Nagasaki killed about 250.000 people and became the most dreadful slaughter of civilians in modern history. However, for many years there was a curious gap in the photographic records. Although the names of Hiroshima and Nagasaki were incised into our memories, there were few pictures to accompany them. Even today, the image in our minds is a mixture of devastated landscapes and shattered buildings. Shocking images of the ruins, but where were the victims?

The American occupation forces imposed strict censorship on Japan, prohibiting anything "that might, directly or by inference, disturb public tranquility" and used it to prohibit all pictures of the bombed cities. The pictures remained classified 'top secret' for many years. Some of the images have been published later by different means, but it's not usual to see them all together. This is the horror they didn't want us to see, and that we must NEVER forget: [1]

Image Source: [1]
Housewives and children were incinerated instantly or paralysed in their daily routines, their internal organs boiled and their bones charred into brittle charcoal. [1]

The atomic bombs dropped on Hiroshima and Nagasaki (6 and 9 August 1945) were the first of their kind. "Little Boy" and "Fat Man"+ were their code nicknames. If this "fire and fury" bluster sounds "familiar," it was likely borrowed from this far more presidential source. 45's impressive uncle likely explained a lot of things to the young millionaire, but his by now well known infamously short attention span, he likely missed a few salient points. Half-life+ is measured in thousands of years, for example. The current yield of thermonuclear versus atomic devices has been proposed to not be measured in mere TNT or megatons, but Hiroshimas.

The pictures above are vile, ugly and a reflection of a dark part of our national soul. "Hindsight being 20/20 vision," our actions may have tragically been utterly and arrogantly unnecessary. [2] We have danced on the edge of this scalpel for three generations that has been the background for a field known as dystopian science fiction, until Carl Sagan's salient warning now bears the hindsight of prophesy. [3] "Duck and cover" drills have become a part of our history of gallows humor, as currently our two malignant narcissistic* heads of state act like prepubescent boys, comparing the size of their phallus symbols, erect and ejaculating like pyromaniacs over the fires of Armageddon. A universe as well as what's left of the Earth will go on.

Humanity: it's been a good run.

The Ysaak War. It is the saga of Moon of Pluton

A second part of the successful book "Moon of Pluton," written by Venezuelan author Ángel David Revilla, better known by his readers as Dross Rotzank, tells how the creation of his latest book and some peculiarities of itself.

Before publishing my first book, I had already written this second part because writing is a passion for me, I'm in love with it. In fact, I opened the Youtube channel with the very premeditated and treacherous idea that publishers would listen to me. Although I later fell in love with this platform for everything it has given me.

The Ysaak War," which began as a short story, but, word for word, became a novel of greater encouragement. "I like to sail on a raft and get into the open sea, and find out how far I'll go. I want to know what I will think of, how I will solve situations ... see what happens. 'The Ysaak War' when I was a story I did not like the end so much, so I added, changed and corrected. So I write, without planning, I enjoy it as much as possible.

The novel, besides being science fiction, mixes the fantasy and goes deep into the characters and their conflicts. For Dross, these qualities relate to the commitment to their readers: to offer the best story.

Milky Way and Einstein...

This artist’s rendition shows the orbits of stars circling the supermassive black hole (blue halo) at the Milky Way’s center. A close analysis suggests the stars’ orbits are showing subtle effects predicted by Einstein’s theory of general relativity. Credit: ESO/M. Parsa/L. Calçada
Topics: Astrophysics, Black Holes, Einstein, General Relativity, Gravity

A giant star near the center of our galaxy hints, once again, that Albert Einstein was correct about gravity.

A group of astronomers in Germany and the Czech Republic observed three stars in a cluster near the supermassive black hole at the center of the Milky Way galaxy. Using data from the Very Large Telescope in Chile, among others, the researchers tracked how the stars moved as they went around the monster black hole.

One of the stars, called S2, showed slight deviations in its orbit that might indicate relativistic effects, scientists said. If the observations are confirmed, then it shows that Einstein's theory of general relativity holds even under extreme conditions — in gravity fields produced by objects like the galactic center's black hole, which contains the mass of 4 million suns. General relativity says that massive objects bend the space around them, causing other objects to deviate from straight lines they would follow absent any forces on them.

the imagineer

I am not much for fantasy, sometimes sci-fi can be a stretch, a futurist, yeah. For a digital artist it can be rough. The concept of fine art looms large with its smell of oil or the quick drying acrylic glaze. The image of one who holds the brush as it were a light saber. The image of the imager frozen in framonite to hang before the gazers with hand to chin. Mind gawkers, all of them, peering ever so close to see if brush hairs were inadvertently glued to the surface. The gallant gallery head bobbles with cha-ching. Then I bring my digital print. Doesn't matter if it is an eleven by eight point five inch print or forty by sixty foot print, they ask the same question with a slight distain, "where is the original?". I am ready this time, "I have it right here" and whip out a tiny micro dot on a business card. "You really can't see it until you put this in a computer or print it out as a did for your easier viewing." "And I got some fume of linseed oil in a Glade mister. I expect the same respect you give lithographers and photographers and block printers. And no you can't do this on your office printer......................ever!" Wait till they start putting human brains in automatons, "ooh where is the original?"

Planet of Doom excerpt

By Lawrence Johnson Sr.

It was a dark time for The Planetary Alliance.  Two of Princess Arianna’s highly regarded warriors Dajus and Mallobo had gone rogue.  Their attacks on the Planetary Alliance and their master computers have thrown the entire galaxy into chaos.  Following the attack and destruction of the intergalactic transport ship the Star Lighter and it 8,000 passengers, members of the Planetary Alliance put in a call to Da’Quan, the best intergalactic detective of his time.  His job seemed simple, locate Dajus and Mallobo and the alliance would do the rest. 

It would be a simple task if it were not for the fact that the two outlaw warriors had the ability to appear and disappear at will.  It would be some time before Da’Quan would meet with his new employers.  As luck would have it Da’Quan’s ship was forced to crash land on the Planet of Doom.

Just before the crash Da’Quan saw the red flashing lights on the Spirit’s console.  He could also hear the warning message constantly blaring over his pa system he named Nano.  “Alert, crash imminent, take preventive measures.”  Something was pulling his ship down to the planet below.  As he struggled to keep his craft airborne Da’Quan noticed a small island up ahead.  It was touch and go for a while but Da’Quan was able to get out a distress call to a friend and land his ship without breaking any bones.

The tall dark haired Da’Quan carefully maneuvered his toned six-foot frame into the chair in front of the console.  ‘Where the hell am I?’ he asked himself. 

After taking a minute to scan his computer charts Da’Quan slumped down into his seat.  He took a deep breath and double checked his charts hoping that he had made an error but there was no doubt about it, Da’Quan had landed on Akanon, better known as the Planet of Doom.  His only hope was to try and repair his ship and leave before he was discovered.

It was midday, the weather was warm, there were no signs of Artificial Intelligence but within a few minutes Da’Quan could hear voices headed in his direction.

A pair of nearby galaxies where "intergalactic transfer" may be happening. (Fred Herrmann)
Topics: Astronomy, Astrophysics, Cosmology

EVANSTON - In a first-of-its-kind analysis, Northwestern University astrophysicists have discovered that, contrary to previously standard lore, up to half of the matter in our Milky Way galaxy may come from distant galaxies. As a result, each one of us may be made in part from extragalactic matter.

Using supercomputer simulations, the research team found a major and unexpected new mode for how galaxies, including our own Milky Way, acquired their matter: intergalactic transfer. The simulations show that supernova explosions eject copious amounts of gas from galaxies, which causes atoms to be transported from one galaxy to another via powerful galactic winds. Intergalactic transfer is a newly identified phenomenon, which simulations indicate will be critical for understanding how galaxies evolve.

“Given how much of the matter out of which we formed may have come from other galaxies, we could consider ourselves space travelers or extragalactic immigrants,” said Daniel Anglés-Alcázar, a postdoctoral fellow in Northwestern’s astrophysics center, CIERA (Center for Interdisciplinary Exploration and Research in Astrophysics), who led the study. “It is likely that much of the Milky Way’s matter was in other galaxies before it was kicked out by a powerful wind, traveled across intergalactic space and eventually found its new home in the Milky Way.”

Lt. Curt Masters, a Tuskegee Airman, is flying a combat mission over the skies of Nazi Germany in 1945. He encounters an alien craft. He engages the craft unsuccessfully. Soon, he is aboard the UFO and is charged with Obstruction of Galactic Operations. He and the people of earth are on trial for their survival. Can Curt Masters free himself from over a billion miles away? Will he ever return home? Or will he die at the hands of The Warlord. In this new universe, he meets Aliena-a Galactic Police officer, Sutter-a mysterious friend or foe and ARC, who is an android without a will of his own. Curt will learn that once you Look Forward you can Never Go Back. Written by Chris Love, this graphic novel offers new worlds and possibilities. A companion feature film has been adapted from this graphic novel.

Tagging...

Electronics small enough to fit inside cells may one day help scientists track individual cells and monitor their behavior in real time, a new study finds. These new devices could help analyze diseases from their origins in single cells, researchers said.

The new electronics are microscopic radio-frequency identification tags, which are essentially bar codes that can be read from a distance.

An RFID tag usually consists of an antenna connected to a microchip. A nearby reader known as a transceiver can emit electromagnetic signals at the tags, and the tags can respond with what data it has stored, such as its identity, when and where it was made, how to best store and handle it, and so on. Many RFID tags do not have batteries -- instead, they rely on the energy in the signals from the transceivers.

These tags are already being used in many applications today, including key cards, toll passes, library books and many other items, but the typical RFID tags are millimeters to centimeters in size. The new microscopic tags in comparison are only 22 microns wide each, or roughly one-fifth the average diameter of a human hair, making them the smallest known RFID tags, the researchers said. They detailed their findings online July 26 in the journal Physical Review Applied.

Photoresist-Free...

Photolithography is an important manufacturing process widely used in the semiconductor industry that employs photoresists (usually made from polymers) whose solubility change when illuminated with ultraviolet light. Although it is precise and can generate patterns with nanoscale resolution, it is limited in that it cannot easily pattern nanomaterials such as quantum dots (which are increasingly being used in flat-panel displays, for example). A new photoresist-free technique, developed by researchers at the University of Chicago and the Argonne National Laboratory, both in Illinois in the US, could help overcome this problem.

“Our new technique, dubbed DOLFIN (for Direct Optical Lithography of Functional Inorganic Nanomaterials) can be used to optically pattern a variety of inorganic materials, including metals, semiconductors, catalysts and magnetic materials without using photoresists,” explains team leader Dmitri Talapin. “No residual polymer-based impurities are present in the patterned layers, which means that they have good electronic and optical properties. Indeed, their conductivity, carrier mobility, dielectric and luminescence properties are on a par with those of state-of-the-art solution-processed materials.”

DOLFIN involves first preparing patternable materials in the form of nanoparticles with the desired size and shape. Next, the surface of these nanoparticles is decorated with special molecules designed to decompose when they are illuminated with UV light.

Aiming at Einstein...

If you cast an observational lasso into the center of the Milky Way galaxy and pull it closed, you will find a dense, dark lump: a mass totaling some four million suns, crammed into a space no wider than twice Pluto’s orbit in our solar system.

In recent years, astronomers have come to agree that inside this region is a supermassive black hole, and that similar black holes lurk at the cores of nearly all other galaxies as well. And for those revelations, they give a lot of credit to Andrea Ghez.

Since 1995, Ghez, an astrophysicist at the University of California, Los Angeles, has used the W.M. Keck telescope on Mauna Kea in Hawaii to see fine details at the center of the galaxy. The observations that Ghez has made of stars racing around the Milky Way’s core (alongside those of rival Reinhard Genzel, an astrophysicist at the Max Planck Institute for Astrophysics in Garching, Germany) have proven to most astronomers that the central object can be nothing but a black hole. But to be able to see these fine details, Ghez had to become a pioneering user of adaptive optics, a technology that measures distortions in the atmosphere and then adjusts the telescope in real time to cancel out those fluctuations. The technique produces images that look as if they were taken under the calmest possible skies.

In Ghez’s mind, new discoveries require that scientists take risks. “If you have a new idea, the thing you are going to encounter first and foremost is ‘no, you can’t do it,’” she said. “I can’t tell you how many times in the course of this project I have been told ‘this won’t work.’” Her first proposal to image the galactic center was turned down; two decades later, Ghez, now 52, has received a MacArthur Fellowship, among other awards, and was the first woman to receive a Crafoord Prize from the Royal Swedish Academy of Sciences.
