Two researchers with the Indian Institute of Science have developed tiny tweezers that can manipulate objects in fluids as small as an individual bacterium. In their paper published in the journal...
View ArticleHard-to-stretch silicon becomes superelastic
As a hard and brittle material, silicon has practically no natural elasticity. But in a new study, researchers have demonstrated that amorphous silicon can be grown into superelastic horseshoe-shaped...
View ArticleWater without windows: Capturing water vapor inside an electron microscope
The inside of an electron microscope, which requires vacuum levels similar to those encountered in outer space, can be an extremely inhospitable place for organic materials. Traditionally, life...
View ArticleNew catalytic effect discovered for producing gallium oxide
Semiconducting oxides are a new class of materials that are currently enjoying great attention in the field of semiconductor technology. Gallium oxide is the archetypal example for its ability to...
View ArticleFreezing electrons makes them get in line
New research published in Nature Communications suggests that electrons in a two-dimensional gas can undergo a semi-ordered (nematic) to mostly-ordered (smectic) phase transition, which has been...
View ArticleWhere did those electrons go? Decades-old mystery solved
The concept of "valence" - the ability of a particular atom to combine with other atoms by exchanging electrons - is one of the cornerstones of modern chemistry and solid-state physics.
View ArticleXenon in the Super Proton Synchrotron—first tests for a photon factory
Accelerator operators can perform amazing acrobatics with particle beams, most recently in the Super Proton Synchrotron (SPS), CERN's second-largest accelerator. For the first time, they have...
View ArticleNew 3-D models illustrate the effect of material roughness on electrons...
Photocathodes used in linear accelerator facilities, free electron lasers and advanced X-ray light sources generate a beam of electrons to probe matter at an atomic level. Advances in materials science...
View ArticleThe moon is a harsh mistress—gravitational impacts on NSLS-II
Night and day, as the moon orbits around earth and the earth around the sun, the gravitational forces of these celestial bodies pull on the earth. This pulling force is what causes the earth's sea...
View ArticleVibrating nanoparticles interact: Placing nanodisks in groups can change...
Like a tuning fork struck with a mallet, tiny gold nanodisks can be made to vibrate at resonant frequencies when struck by light. In new research, Rice University researchers showed they can...
