Artificial Forest for Solar Water-Splitting
Berkeley Lab researchers have created the first fully integrated artificial photosynthesis nanosystem. While “artificial leaf” is the popular term for such a system, the key to this success was an “artificial forest.”
Chromatography Goes Gold: Gold Nanoparticles and Monoliths Make a Perfect Match
The power of chromatography for studying proteins and peptides can be substantially boosted with the addition of gold nanoparticles to polymer monolith surfaces.
Black Gold: Enabling Bright, High Rep-Rate Electron Beams
Free electron lasers (FELs) have proven their worth, but next-generation light sources will have to do better than produce ultrabright x-ray pulses 100 or so times a second. What’s needed is megahertz rep rate, a million times a second. Since it’s electrons that make the x-rays, the only way to achieve that kind of performance [...]
Flexing fingers for micro-robotics: Berkeley Lab scientists create a powerful, microscale actuator
Researchers with Berkeley Lab and UC Berkeley have developed an elegant and powerful new microscale actuator that can flex like a tiny beckoning finger. Based on an oxide material that expands and contracts dramatically in response to a small temperature variation, the actuators are smaller than the width of a human hair and are promising for microfluidics, drug delivery, and artificial muscles.
Nanocrystals Not Small Enough to Avoid Defects
A team of researchers from Berkeley Lab and other institutes has shown that contrary to computer simulations, the tiny size of nanocrystals is no safeguard from defects. Studies at Berkeley Lab’s Advanced Light Source show that dislocations can form in the finest of nanocrystals when stress is applied.
The Best of Both Catalytic Worlds
Berkeley Lab researchers have combined the best properties of heterogeneous and homogeneous catalysts by encapsulating metallic nanoclusters within the branched molecular arms of dendrimers. The results are heterogenized homogeneous nanocatalysts that are sustainable and feature high reactivity and selectivity.
