A team of scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, in collaboration with researchers from the University of Delaware and Yeshiva University, has developed a new catalyst that could make ethanol-powered fuel cells feasible. The highly efficient catalyst ...
DFG-funded instrumentation enables world-class research in electron microscopy
Two new high-resolution transmission electron microscopes, co-financed by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation), are set to open up new opportunities for research in physics and materials science. The new research microscopes at RWTH Aachen University and the ...
Because they are riddled with defects, bulk crystalline materials never achieve their ideal strength; nanocrystals, on the other hand, are so small there's no room for defects. Yet while nanocrystalline materials may approach ideal strength in their resistance to stress, most nanostructures have ...
Bilayer clusters of atoms less than a nanometer in dimension are found to be responsible for a vital oxidation reaction
Few materials have exercised as much of a hold on the human imagination, or on human history, as has gold. But for all of its popular uses – money, medals, jewelry and more – gold's potential as a catalyst lay hidden until the 1980s, when Masatake Haruta and Graham Hutchings independently ...
Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have developed a new method for controlling the self-assembly of nanometer and micrometer-sized particles. The method, based on designed DNA shells that coat a particle's surface, can be used to manipulate the structure ...
Using DNA, the molecule that carries life's genetic instructions, researchers at the U.S. Department of Energy's Brookhaven National Laboratory are studying how to control both the speed of nanoparticle assembly and the structure of its resulting nanoclusters. Learning how to control and tailor ...
New ways to tag, engineer molecules for energy conversion, drug delivery, and medical imaging
In groundbreaking research, scientists have demonstrated the ability to strategically attach gold nanoparticlesto proteins so as to form sheets of protein-gold arrays. The nanoparticles and methods to create nanoparticle-protein complexes can be used to help decipher protein structures, to ...
Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have developed a screening method to examine how newly made nanoparticles interact with human cells following exposure for various times and doses. This has led to the visualization of how human cells interact with some ...
The design, development and manufacturing of revolutionary products such as the automobile, airplane and computer owe a great deal of their success to the large-scale material testing systems (MTS) that have provided engineers and designers with a fundamental understanding of the mechanical ...
