Oct. 8, 2015 — Most materials swell when warm, and shrink when cool. But some weird materials do the opposite. Although thermal expansion, and the cracking and warping that often result, occurs everyday -- in ... read more

Super Yellow Blends for Light Efficiency

Oct. 6, 2015 — A new study details ultrahigh efficiency, low voltage polymer light emitting diodes (PLEDs) to maximize light output from devices. A blend of two polymers can be used to boost the efficiency of LEDs ... read more

Oct. 6, 2015 — A new physical effect has been discovered: Researchers have found a change of electrical resistance in magnetic whirls. Tiny magnetic whirls – so called skyrmions – are being considered as ... read more

Oct. 6, 2015 — As the push for thinner and faster electronics continues, a new finding could help inform the design of the next generation of cheaper, more efficient ... read more

Physicists Shrink Particle Accelerator

Oct. 6, 2015 — Researchers have built the first prototype of a miniature particle accelerator that uses terahertz radiation instead of radio frequency structures. The terahertz technology holds the promise of ... read more

Oct. 5, 2015 — The efficiency of solar cells depends on precise engineering of polymers that assemble into films 1,000 times thinner than a human hair. Today, formation of that polymer assembly requires solvents ... read more

Oct. 5, 2015 — A two-dimensional crystal, combined with graphene, has the capability to detect optical pulses with a response faster than 10 picoseconds, while maintaining a high efficiency, a new study ... read more

Oct. 5, 2015 — A newly upgraded high-power laser will blaze new trails across many fields of science by recreating the universe’s most extreme conditions, such as those at the heart of stars and planets, in a ... read more

Oct. 5, 2015 — Perovskite solar cells are cheaper to make than traditional silicon cells and their electricity conversion efficiency is improving rapidly. To be commercially viable, perovskite cells need to scale ... read more

Oct. 5, 2015 — Researchers have created tiny pores in single sheets of graphene that have an array of preferences and characteristics similar to those of ion channels in living ... read more

Flame Retardant Breakthrough Is Naturally Derived, Nontoxic

Oct. 5, 2015 — A new flame retardant has been created to replace commercial additives that are often toxic and can accumulate over time in the environment and living animals, including ... read more

Oct. 5, 2015 — Scientists have used a transmission electron microscope to record almost 3500 images in 3.5 seconds for the reconstruction of a 3D electron tomogram. Previously, 10 to 60 minutes and a ten-fold ... read more

Oct. 5, 2015 — When pathologists perform autopsies on smokers who died with severe emphysema, they find that lungs are black in appearance. Until recently, researchers and physicians could only guess at the ... read more

Oct. 5, 2015 — A model microscopic system to demonstrate the transmission of torque in the presence of thermal fluctuations -- necessary for the creation of a tiny 'clutch' operating at the nanoscale -- ... read more

Oct. 5, 2015 — Physicists have developed a method to synthesize a unique and novel type of material which resembles a graphene nanoribbon but in molecular form. This material could be important for the further ... read more

Oct. 5, 2015 — Scientists have made simulations of the processes that happen when a layer of carbon atoms is irradiated with strong laser ... read more

Oct. 4, 2015 — The world's first entirely light-based memory chip to store data permanently has been developed by material scientists. The device, which makes use of materials used in CDs and DVDs, could help ... read more

Oct. 5, 2015 — A series of experiments has created the tiniest drops of quark-gluon plasma ever made, scientists ... read more

Oct. 2, 2015 — Theoretically, nanocellulose could be the next hot supermaterial. A new computational approach allows researchers to design cellulose nanocomposites with optimal properties, resulting in materials ... read more

Oct. 2, 2015 — A team of researchers has developed an elegant process for coating fragile perovskite layers with graphene for the first time. Subsequent measurements show that the graphene layer is an ideal front ... read more
