Michael Harper for redOrbit.com — Your Universe Online Scientists have been finding ways to shrink electronic circuits ever since they were first invented. But no matter how small these circuits get, they´ve been largely confined to rigid surfaces, typically silicon. Now, one University of Pennsylvania team have set out to free the electronic circuit from its stiff and rigid existence and, just as many other researchers have been doing in recent years, they looked to...

Medical uses for quantum dots -- tiny luminescent crystals -- could include image-guided surgery, light-activated therapies and sensitive diagnostic tests A pioneering study to gauge the toxicity of quantum dots in primates has found the tiny crystals to be safe over a one-year period, a hopeful outcome for doctors and scientists seeking new ways to battle diseases like cancer through nanomedicine. The research, which will appear on May 20 in Nature Nanotechnology online, is likely the...

Berkeley Lab Researchers Discover Why Pure Quantum Dots and Nanorods Shine Brighter To the lengthy list of serendipitous discoveries — gravity, penicillin, the New World — add this: Scientists with the U.S. Department of Energy (DOE)´s Lawrence Berkeley National Laboratory (Berkeley Lab) have discovered why a promising technique for making quantum dots and nanorods has so far been a disappointment. Better still, they´ve also discovered how to correct the problem. A...

Imagine if the next coat of paint you put on the outside of your home generates electricity from light–electricity that can be used to power the appliances and equipment on the inside. A team of researchers at the University of Notre Dame have made a major advance toward this vision by creating an inexpensive "solar paint" that uses semiconducting nanoparticles to produce energy. "We want to do something transformative, to move beyond current silicon-based solar technology," says...

Quantum dots made from cadmium and selenium degrade in soil, unleashing toxic cadmium and selenium ions into their surroundings, a University at Buffalo study has found. The research, accepted for publication in the journal Environmental Science and Technology, demonstrates the importance of learning more about how quantum dots -- and other nanomaterials -- interact with the environment after disposal, said Diana Aga, the chemistry professor who led the study. Quantum dots are semiconductor...

Berkeley Lab Scientists Find Unique Luminescence in Tetrapod Nanocrystals Observation of a scientific rule being broken can sometimes lead to new knowledge and important applications. Such would seem to be the case when scientists with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) created artificial molecules of semiconductor nanocrystals and watched them break a fundamental principle of photoluminescence known as "Kasha's rule." Named for chemist...

An interdisciplinary team of researchers at UC Santa Barbara has produced a groundbreaking study of how nanoparticles are able to biomagnify in a simple microbial food chain. "This was a simple scientific curiosity," said Patricia Holden, professor in UCSB's Bren School of Environmental Science & Management and the corresponding author of the study, published in an early online edition of the journal Nature Nanotechnology. "But it is also of great importance to this new field of looking...

Breakthrough discovery enables nanoscale manipulation of the piezoelectric effect The generation of an electric field by the compression and expansion of solid materials is known as the piezoelectric effect, and it has a wide range of applications ranging from everyday items such as watches, motion sensors and precise positioning systems. Researchers at McGill University's Department of Chemistry have now discovered how to control this effect in nanoscale semiconductors called "quantum dots,"...

If the promise of nanotechnology is to be fulfilled, nanoparticles will have to be able to make something of themselves. An important advance towards this goal has been achieved by researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) who have found a simple and yet powerfully robust way to induce nanoparticles to assemble themselves into complex arrays. By adding specific types of small molecules to mixtures of nanoparticles and polymers, the...

Word of the Day
  • Like a worm in form or movement; vermiform; tortuous or sinuous; also, writhing or wriggling.
  • Like the track or trace of a worm; appearing as if worm-eaten; vermiculate.
  • Marked with fine, close-set, wavy or tortuous lines of color; vermiculated.
  • A form of rusticated masonry which is so wrought as to appear thickly indented with worm-tracks.
This word ultimately comes from the Latin 'vermis,' worm.
