Red Glow Helps Identify Nanoparticles for Delivering RNA Therapies

A new screening process could dramatically accelerate the identification of nanoparticles suitable for delivering therapeutic RNA into living cells.
Researchers have developed a technique for producing platinum hollow nanocages with ultra-thin walls that could dramatically reduce the amount of the costly metal needed to provide catalytic activity in such applications as fuel cells. The image shows models of the (left) cubic and (octahedral) nanocages, whose surfaces are covered by atoms in square and hexagonal arrays, respectively. The yellow spheres correspond to platinum atoms while the green spheres indicate a small fraction of palladium atoms remain
Ultra-thin Hollow Nanocages Could Reduce Platinum Use in Fuel Cell Electrodes

A new fabrication technique could reduce the amount of platinum needed for fuel cell electrodes.
