Researchers slow light to a crawl in liquid crystal matrix
(Phys.org) —Light traveling in a vacuum is the Universe's ultimate speed demon, racing along at approximately 300,000 kilometers per second. Now scientists have found an effective new way to put a speed ...
Simulation shows colloids can form into non-crystalline state at below freezing temperatures
One chemical forms two colors of crystals, sheds insight on agostic bonds important in industrial catalysis
Chemists have unexpectedly made two differently colored crystals – one orange, the other blue – from one chemical in the same flask while studying a special kind of molecular connection called an agostic ...
NASA selects eight physical science research proposals
NASA's Physical Science Research Program will fund eight proposals to help investigate how complex fluids and macromolecules behave in microgravity. The investigations will be conducted aboard the International Space Station.
OLED brings out the shine
Screens made of organic light diodes promise unfathomable possibilities. Yet high production costs often prevent their widespread use. A new kind of production saves not only costs, but also improves the ...
Spheres can form squares
Everybody who has tried to stack oranges in a box knows that a regular packing of spheres in a flat layer naturally leads to a hexagonal pattern, where each sphere is surrounded by six neighbours in a honeycomb-like ...
Study provides better understanding of water's freezing behavior at nanoscale
The results of a new study led by George Washington University Professor Tianshu Li provide direct computational evidence that nucleation of ice in small droplets is strongly size-dependent, an important conclusion ...
Beautiful 'flowers' self-assemble in a beaker
By simply manipulating chemical gradients in a beaker of fluid, materials scientists at Harvard have found that they can control the growth behavior of crystals to create precisely tailored structures—such ...
Sharp reshuffles management after record loss (Update)
Japanese electronics maker Sharp Corp. named a new president Tuesday, reshuffling its top management to help restore profitability after reporting a record loss.
'Going negative' pays for nanotubes: Team finds possible keys to better nanofibers, films
(Phys.org) —A Rice University laboratory's cagey strategy turns negatively charged carbon nanotubes into liquid crystals that could enhance the creation of fibers and films.
A liquid crystal force to reckon with
A need for fast, solution-based processing of organic electronic devices has sparked increased interest in 'discotic' or disc-shaped liquid crystals. These molecules, which contain a flat aromatic core surrounded ...
Silicone liquid crystal stiffens with repeated compression
(Phys.org) —Squeeze a piece of silicone and it quickly returns to its original shape, as squishy as ever. But scientists at Rice University have discovered that the liquid crystal phase of silicone becomes ...
University of Houston engineering researcher's theories to be tested in space
A University of Houston chemical and biomolecular engineering professor's theories on crystal formation will be tested aboard the International Space Station (ISS).
Optics innovation an industry success
An optics innovation by a University of Sydney researcher has been a financial and technology transfer success story creating a wave of sales for Finisar, the Australian company that has used the new technology.
