A graphene barrier to precisely control molecules for making nanoelectronics

21-Jan-2016

Scientists from UCLA’s California NanoSystems Institute have found that the same basic approach is an effective way to place molecules in the specific patterns they need within tiny nanoelectronic devices. The technique could be useful in creating sensors that are small enough to record brain ...

Iron-gallium alloy shows promise as a power-generation device

30-Sep-2015

An alloy first made nearly two decades ago by the U. S. Navy could provide an efficient new way to produce electricity. The material, dubbed Galfenol, consists of iron doped with the metal gallium. In new experiments, researchers from UCLA, the University of North Texas (UNT), and the Air Force ...

Physicists determine 3-D positions of individual atoms for the first time

23-Sep-2015

Atoms are the building blocks of all matter on Earth, and the patterns in which they are arranged dictate how strong, conductive or flexible a material will be. Now, scientists at UCLA have used a powerful microscope to image the three-dimensional positions of individual atoms several times ...

Physicist tests theories of dark energy by mimicking the vacuum of space

24-Aug-2015

Ever since dark energy was discovered in 1998, scientists have been proposing theories to explain it - one is that dark energy produces a force that can be measured only where space has a very low density, like the regions between galaxies. Paul Hamilton, a UCLA assistant professor of physics and ...

Secrets of enzyme used to make popular anti-cholesterol drug

15-May-2014

In pharmaceutical production, identifying enzyme catalysts that help improve the speed and efficiency of the process can be a major boon. Figuring out exactly why a particular enzyme works so well is an altogether different quest. Take the cholesterol-lowering drug simvastatin. First marketed ...

Better separations with more permeable membranes

17-Sep-2013

Researchers in the United States have developed a new type of nanocomposite ultrafiltration membrane that overcomes the usual trade-off between selectivity and liquid permeability associated with ultrafiltration membranes. When designing a membrane for the ultrafiltration of proteins from a ...

UCLA physicists' technique for cooling molecules may be a stepping stone to quantum computing

02-Apr-2013

The next generation of computers promises far greater power and faster processing speeds than today's silicon-based based machines. These "quantum computers" — so called because they would harness the unique quantum mechanical properties of atomic particles — could draw their computing power from ...

Imaging methodology reveals nano details not seen before

Understanding nanoparticles at atomic scale in 3 dimensions could improve materials

02-Apr-2013

A team of scientists from the University of California, Los Angeles (UCLA) and Northwestern University has produced 3-D images and videos of a tiny platinum nanoparticle at atomic resolution that reveal new details of defects in nanomaterials that have not been seen before. Prior to this work, ...
