Journal of Crystal Growth, 1973
Abstract FeCr 2 S 4 single crystals were grown by vapor transport in a closed system using first Cl 2 and a mixture of HCl+Cl 2 . Thermodynamic calculations show that chemical transport is only possible using HCl+Cl 2 as transport agent. Composition of the gas phase in equilibrium with the solid is derived from thermodynamic calculations.

The use of chemical restraint in helicopter transport
Air Medical Journal, 1999Helicopter transport of the combative patient is a major safety hazard facing air medical teams. Although physical restraints alone are helpful, the addition of chemical restraint (CR) often is necessary to control these patients while in flight.A survey was conducted to determine the current practices of using nonparalyzing CR in air medical transport

Chemical enhancers for transdermal drug transport
European Journal of Drug Metabolism and Pharmacokinetics, 2001In its first part, this review paper discusses skin morphology and barrier function of the stratum corneum for drug permeation after its transdermal administration or topical application. Further, the paper presents the main methods for overcoming the skin permeation barrier, which plays an important role for transdermal drug administration.

Chemical neuroanatomy of the vesicular amine transporters
The FASEB Journal, 2000ABSTRACT Acetylcholine, catecholamines, serotonin, and histamine are classical neurotransmitters. These small molecules also play important roles in the endocrine and immune/inflammatory systems. Serotonin secreted from enterochromaffin cells of the gut epithelium regulates gut motility; histamine secreted from ...

Characterization of chemical agent transport in paints
Journal of Hazardous Materials, 2013A combination of vacuum-based vapor emission measurements with a mass transport model was employed to determine the interaction of chemical warfare agents with various materials, including transport parameters of agents in paints. Accurate determination of mass transport parameters enables the simulation of the chemical agent distribution in a material

Rail tankcar chemical spills continue to draw public and government concern. California was hit last week with its second rail accident releasing a hazardous chemical in less than a month, when 14 container cars of a Southern Pacific train derailed on July 28 in Sea Cliff.

Chemical transport ofβ-Ga2O3 using chlorine as a transporting agent
Journal of Materials Science, 1986The chemical transport of Ga2O3 with chlorine as a transporting agent has been investigated. Thermochemical properties of gallium chlorides have been considered on the basis of literature data. Thermodynamic analysis of transport reactions at 600 to 1500 K has been performed and GaCl3 was found the predominant gallium chloride in the vapour phase.

Charge Transport in Chemically Doped 2D Graphene
Physical Review Letters, 2008We report on a numerical study of electronic transport in chemically doped 2D graphene materials. By using ab initio calculations, a self-consistent scattering potential is derived for boron and nitrogen substitutions, and a fully quantum-mechanical Kubo-Greenwood approach is used to evaluate the resulting charge mobilities and conductivities of ...

A model in the here discussed form is first of all a description of complex processes in nature. This starts with a description by words or graphics (conceptual model) and goes up to complex mathematical or numerical simulation models that run on supercomputers. The complexity of a model is determined by several factors.
