Imaging methodology reveals nano details not seen before
Understanding nanoparticles at atomic scale in 3 dimensions could improve materials
02-04-2013
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 ...
UCLA physicists' technique for cooling molecules may be a stepping stone to quantum computing
02-04-2013
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 ...
New insights into how the most iconic reaction in organic chemistry really works
Diels and Alder won the Nobel; now UCLA's Kendall Houk makes the movie
12-07-2012
In 1928, chemists Otto Diels and Kurt Alder first documented diene synthesis, a chemical reaction important for synthesizing many polymers, alkaloids and steroids. Their work on this mechanism, which came to be known as the Diels–Alder reaction, won them the 1950 Nobel Prize in ...
UCLA Engineering researchers use electricity to generate alternative fuel
03-04-2012
Imagine being able to use electricity to power your car — even if it's not an electric vehicle. Researchers at the UCLA Henry Samueli School of Engineering and Applied Science have for the first time demonstrated a method for converting carbon dioxide into liquid fuel isobutanol using ...
UCLA bioengineers discover how particles self-assemble in flowing fluids
17-12-2010
From atomic crystals to spiral galaxies, self-assembly is ubiquitous in nature. In biological processes, self-assembly at the molecular level is particularly prevalent. Phospholipids, for example, will self-assemble into a bilayer to form a cell membrane, and actin, a protein that supports ...
Study measures single-molecule machines in action
09-07-2010
In the development of future molecular devices, new display technologies, and "artificial muscles" in nanoelectromechanical devices, functional molecules are likely to play a primary role. Rotaxanes, one family of such molecules, are tiny, mechanically interlocked structures that consist of ...
Cycloadditions go with the crowd
28-06-2010
A new mechanism for the control of cycloaddition stereochemistry by a well known chiral auxiliary has been discovered. The findings may prompt organic chemists to rethink their synthetic routes to achieve the product they want. Cycloadditions are important routes for making organic ring ...
UCLA's James Liao receives Presidential Green Chemistry Challenge Award from EPA
23-06-2010
James C. Liao, the Chancellor's Professor of Chemical and Biomolecular Engineering at the UCLA Henry Samueli School of Engineering and Applied Science, has been awarded the 2010 Presidential Green Chemistry Challenge Award from the U.S. Environmental Protection Agency. The award promotes ...
New silicon-germanium nanowires could lead to smaller, more powerful electronic devices
11-12-2009
Microchip manufacturers have long faced challenges miniaturizing transistors, the key active components in nearly every modern electronic device, which are used to amplify or switch electronic signals. Now, researchers from the UCLA Henry Samueli School of Engineering and Applied Science, ...
Chemists get custom-designed microscopic particles to self-assemble in liquid crystal
30-11-2009
Chemists and physicists have succeeded in getting custom-shaped microparticles to interact and self-assemble in a controlled way in a liquid crystal. The research, federally funded by the National Science Foundation, appeared in the Nov. 20 edition of the journal Science. "We're learning ...
