Title: Ex-situ doped semiconductor transport layer

Abstract

A method of making an ex-situ doped semiconductor transport layer for use in an electronic device includes: growing a first set of semiconductor nanoparticles having surface organic ligands in a colloidal solution; growing a second set of dopant material nanoparticles having surface organic ligands in a colloidal solution; depositing a mixture of the first set of semiconductor nanoparticles and the second set of dopant material nanoparticles on a surface, wherein there are more semiconductor nanoparticles than dopant material nanoparticles; performing a first anneal of the deposited mixture of nanoparticles so that the organic ligands boil off the surfaces of the first and second set of nanoparticles; performing a second anneal of the deposited mixture so that the semiconductor nanoparticles fuse to form a continuous semiconductor layer and the dopant material atoms diffuse out from the dopant material nanoparticles and into the continuous semiconductor layer.

Method for in situ or ex situ bioremediation of hexavalent chromium contaminated soils and/or groundwater

Patent Turick, Charles E [Idaho Falls, ID]; Apel, William W [Idaho Falls, ID]

A method of reducing the concentration of Cr(VI) in a liquid aqueous residue comprises the steps of providing anaerobic Cr(VI) reducing bacteria, mixing the liquid aqueous residue with a nutrient medium to form a mixture, and contacting the mixture with the anaerobic Cr(VI) reducing bacteria such that Cr(VI) is reduced to Cr(III). The anaerobic Cr(VI) reducing bacteria appear to be ubiquitous in soil and can be selected by collecting a soil sample, diluting the soil sample with a sterile diluent to form a diluted sample, mixing the diluted sample with an effective amount of a nutrient medium and an effectivemore » « less

A method and apparatus for ex-situ nuclear magnetic resonance spectroscopy for use on samples outside the physical limits of the magnets in inhomogeneous static and radio-frequency fields. Chemical shift spectra can be resolved with the method using sequences of correlated, composite z-rotation pulses in the presence of spatially matched static and radio frequency field gradients producing nutation echoes. The amplitude of the echoes is modulated by the chemical shift interaction and an inhomogeneity free FID may be recovered by stroboscopically sampling the maxima of the echoes. In an alternative embodiment, full-passage adiabatic pulses are consecutively applied. One embodiment of themore » « less
