The de novo-predicted and X-ray-confirmed structure of the organic thiol-capped AuAg16(SR)12 cluster. The cluster is comprised of a central icosahedral (AuAg12, made of a gold atom surrounded by twelve silver atoms), capped by four AgS3 mounts, each made of a triangle of sulfur atoms, in yellow, bonded to an anchoring silver atom (black). Each of the twelve sulfur atoms is bonded to an aromatic phenyl ring which is crowned by a tetrabutyl group C(CH3)3. Most of the aromatic rings are organized in dimer bund

Hybrid Approach Predicts and Confirms Structure of Complex Metal Nanoparticles

Engineering Professor Hang Lu holds up a chip used to immobilize C. elegans roundworms for photographing by a microscope optic connected to a computer. The chip then sorts the worms into one of two channels for either mutants or non-mutants, a status an algorythm determines based on subtle phenotypical differences it recognizes in the microscope photo.
