Generalized gradient approximations (GGA's) for the exchange-correlation energy improve upon the local spin density (LSD) description of atoms, molecules, and solids. We present a simple derivation of a simple GGA, in which all parameters (other…

A self-assembled monolayer of 1-octanethiol was prepared on a Au(111) surface via liquid-phase adsorption. An investigation of the surface using ultrahigh-vacuum scanning tunneling microscopy revealed a striped phase of the octanethiol molecules…

A Second Generation Force Field for the Simulation of Proteins, Nucleic Acids, and Organic MoleculesWe present the derivation of a new molecular mechanical force field for simulating the structures, conformational energies, and interaction energies of proteins, nucleic acids, and many related organic molecules in condensed phases. This effective…

We tested the hypothesis that single nucleotide polymorphisms (SNPs) within genes of the NF-κB pathway are associated with altered clinical outcome of septic shock patients. We genotyped 59 SNPs in the NF-κB pathway in a discovery cohort of septic…

The dependence of the optical properties of spherical gold nanoparticles on particle size and wavelength were analyzed theoretically using multipole scattering theory, where the complex refractive index of gold was corrected for the effect of a…

The extinction coefficient per mole of nanocrystals, epsilon, for cadmium chalcogenides nanocrystals was found to be dependent on the size of the nanocrystals, between a square and a cubic dependence, although existing theories predict a…

A simple route to the production of high-quality CdE (E = S, Se, Te) semiconductor nanocrystallites is presented. Crystallites from approximately 12 angstrom to approximately 115 angstrom in diameter with consistent crystal structure, surface…

Nanocrystals are fundamental to modern science and technology. Mastery over the shape of a nanocrystal enables control of its properties and enhancement of its usefulness for a given application. Our aim is to present a comprehensive review of…

Cysteine is commonly used to attach peptides onto gold surfaces. Here we show that the inclusion of an additional linker with a length of four residues (-PPPPC) and a rigid, hydrophobic nature is a better choice for forming peptide self-assembled…

THE synthesis of molecular carbon structures in the form of C60 and other fullerenes 1 has stimulated intense interest in the structures accessible to graphitic carbon sheets. Here I report the preparation of a new type of finite carbon structure…

This paper deals with the ground state of an interacting electron gas in an external potential v(r). It is proved that there exists a universal functional of the density, Fn(r), independent of v(r), such that the expression Ev(r)n(r)dr+Fn(r) has as…

Colloidal nanocrystals are solution-grown, nanometre-sized, inorganic particles that are stabilized by a layer of surfactants attached to their surface. The inorganic cores possess useful properties that are controlled by their composition, size and…

The needle trap device (NTD) is an extraction trap that contains a sorbent inside a small needle, through which fluid can be actively drawn into and out of by a gas-tight syringe or pump, or analytes can be introduced passively to the trap by…

THE large-scale use of photovoltaic devices for electricity generation is prohibitively expensive at present: generation from existing commercial devices costs about ten times more than conventional methods 1. Here we describe a photovoltaic cell,…

The optical properties of metal nanoparticles have long been of interest in physical chemistry, starting with Faradays investigations of colloidal gold in the middle 1800s. More recently, new lithographic techniques as well as improvements to…

For binary mixtures the phase separation depends on various typical parameters like pressure and temperature. In addition, in 1965 Debye and Kleboth showed that it can also be influenced by external electric fields. They found that a moderate…
