Channeling studies of the location of zinc in GaAs
… with the ALCHEMI technique (Atom Location by CHanneling Enhanced Microanalysis) in a Transmission Electron Microscope (TEM). This required substantial enhancements to the x-ray microanalytic abilities of the TEM along with an improved understand of the nature of the illumination in the …

Channeling studies of the location of zinc in gallium-arsenide
The diffusion of zinc in GaAs is highly anomalous in that the diffusion coefficient (D) is proportional to the zinc concentration squared in marked contrast to Fick's law which predicts that D is concentration independent. D is also very sensitive to the ambient conditions during diffusion, …

Experiments and simulation of transverse cooling and heating in ion channeling
Within the theory of ion channeling in single crystals the so-called rule of reversibility claims equal probabilities for de- and rechanneling. However, the experimental study of this work shows a strong violation of this rule. Specially developed computer simulations provide the explanation of …

Investigation of Planar Channeling Radiation on Diamond and Quartz Crystals at Electron Energies between 14 and 34 MeV and Probing the Influence of Ultrasonic Waves on Channeling Radiation
The first measurements of CR at the Radiation source ELBE of the Forschungszentrum Dresden-Rossendorf have been performed in the fall of 2003, where the most important attempt for an application of CR in radiobiological research was the optimization of its yield and spectral line width as well. …

The role of coastal defence structures in channeling production in coastal ecosystems
This study assessed the interaction of coastal defence structures (CDSs), namely shore-parallel<br/>‘low crested breakwater structures’ (LCSs), design features and hydrodynamic regime on the<br/>quantity and timings of macroalgae deposition. The employed sampling strategy comprised a<br/>spatially …

A backscattering ion channeling study of the lattice site location of the constituents of two systems
Backscattering ion channeling measurements were performed to determine the lattice site location of the constituents of two systems. For (GaSb) 1_x(Ge2)x spectra were obtained at a set of incident beam orientations along an angular scan through the [110] direction and nearly parallel to the [110) …

The Mental Health Of Athletes: Channeling Frustration, Aggression, Internal/External Behaviors In The Real World To Improve Performance
<p>This qualitative study examined how college athletes, 18 years and older, experience and interpret internalizing behaviors and externalizing behaviors within contact and non-contact sports, and how those experiences are shaped by gender, racial/ethnic background, and socioeconomic status. The …

Investigation of implantation damage in aluminum gallium arsenide/gallium arsenide heterostructures using ion channeling and transmission electron microscopy
… Rutherford backscattering spectrometry ion channeling and room-temperature transmission electron microscopy techniques. In all implantations the level of damage produced in these structures was found to increase with depth, and the damage state produced in samples containing single- and …

Channeling in purine biosynthesis : efforts to detect interactions between PurF and PurD and characterization of the FGAR-AT complex
… one strategy cells could employ is channeling-the direct transfer of a metabolite between enzyme active sites without diffusion into the bulk media. While kinetic evidence for channeling of PRA has been reported between phosphoribosylpyrophosphate amidotransferase (PurF) and …

X-Ray Generation by Mev Electrons in Silicon: Temperature, Tilt and Thickness Dependence
… crystal lattice. The other type of radiation is channeling radiation. The electrons channeling near major crystal axes enter quantized orbits and emit x-ray photons as a consequence of transitions between orbits.

On the length-scale and location of channel nucleation in directional solidification
… of the length scale D/ V, where it is shown that channeling can be turned on or off simply by changing this length scale. This work also validates a finite element model of dendritic solidification by comparing predicted results to data resulting from eleven directionally solidified hypoeutectic …
