Magnetoelectronics
An approach to electronics is emerging that is based on the up or down spin of the carriers rather than on electrons or holes as in traditional semiconductor electronics. The ph...
Crystal Structure and Pair Potentials: A Molecular-Dynamics Study
With use of a Lagrangian which allows for the variation of the shape and size of the periodically repeating molecular-dynamics cell, it is shown that different pair potentials l...
Self-Assembly and Mineralization of Peptide-Amphiphile Nanofibers
We have used the pH-induced self-assembly of a peptide-amphiphile to make a nanostructured fibrous scaffold reminiscent of extracellular matrix. The design of this peptide-amphi...
Perspectives on the Physical Chemistry of Semiconductor Nanocrystals
Semiconductor nanocrystals exhibit a wide range of size-dependent properties. Variations in fundamental characteristics ranging from phase transitions to electrical conductivity...
Single Sheet Functionalized Graphene by Oxidation and Thermal Expansion of Graphite
A detailed analysis of the thermal expansion mechanism of graphite oxide to produce functionalized graphene sheets is provided. Exfoliation takes place when the decomposition ra...
Engineering Flows in Small Devices: Microfluidics Toward a Lab-on-a-Chip
Microfluidic devices for manipulating fluids are widespread and finding uses in many scientific and industrial contexts. Their design often requires unusual geometries and the i...
Metal-organic frameworks
Metal-organic frameworks are a recently-identified class of porous polymeric material, consisting of metal ions linked together by organic bridging ligands, and are a new develo...
Monitoring dopants by Raman scattering in an electrochemically top-gated graphene transistor
The recent discovery of graphene has led to many advances in two-dimensional physics and devices. The graphene devices fabricated so far have relied on SiO(2) back gating. Elect...
