Seyedali Emami、Filipe A. Almeida Paz、Adélio Mendes 等 4 位作者2014-07-25Crystal Growth & Design

Single amino acids have been vastly used to generate metal–biomolecule frameworks. Three-dimensional (3D) frameworks based on di- and tripeptide frameworks remain nevertheless quite scarce. We report the preparation of unique 3D dipeptide–metal frameworks in which both amino acid residues participate in metal coordina…

One pot synthesis of nanoscale phase-segregated PdPt nanoarchitectures via unusual Pt-doping induced structural reorganization of a Pd nanosheet into a PdPt nanotent

Jong‐Sik Park、Aram Oh、Hionsuck Baik 等 6 位作者2014-07-25Nanoscale

Pt-doping of an ultrathin Pd nanosheet results in the unprecedented structural rearrangement of a Pd nanosheet into a PdPt nanotent structure, in which a tripod stands on a triangular nanosheet. Further growth of Pt phase on this nanotent structure is dependent on the presence of surface-stabilizing CO molecules, lead…

Organic magnetoresistance from deep traps

N. J. Harmon、M. E. Flatté2014-07-25Journal of Applied Physics

We predict that singly occupied carrier traps, produced by electrical stress or irradiation within organic semiconductors, can cause spin blockades and the large room-temperature magnetoresistance known as organic magnetoresistance. The blockade occurs because many singly occupied traps can only become as doubly occup…
