New technique maps twin faces of smallest Janus nanoparticles

(PhysOrg.com) -- New drug delivery systems, solar cells, industrial catalysts and video displays are among the potential applications of special particles that possess two chemically distinct sides. These particles are named ...

Opposites Attract and Inspire Electrocatalyst

(PhysOrg.com) -- Tiny gold particles will surround themselves with even smaller platinum bits, creating a complex structure that could turn a common preservative, formic acid, into electricity in a fuel cell, according to ...

Monitoring the lifecycle of tiny catalyst nanoparticles

Nanoparticles can be used in many ways as catalysts. To be able to tailor them in such a way that they can catalyse certain reactions selectively and efficiently, researchers need to determine the properties of single particles ...

Guided growth of nanowires leads to self-integrated circuits

Researchers working with tiny components in nanoelectronics face a challenge similar to that of parents of small children: teaching them to manage on their own. The nano-components are so small that arranging them with external ...
