The stress-mediated diffusion of nonequilibrium point defects into the bulk of a semiconductor is investigated by computer simulation.
Our findings have important implications for understanding the microstructure and precipitation behaviour of Ni-based superalloys, suggesting a transition in the mechanism of vacancy-mediated diffusion of Al from intrasublattice exchange at high temperatures to intersublattice antisite-assisted exchange at low temperatures.
Reaction and metabolite counts represent reactions found in the cytosol and periplasm, since EcoCyc 18.0 GEM does not cover porin-mediated diffusion of metabolites into the periplasmic space.
Cr has been shown to more readily access the fetal rodent brain than the mature adult brain, possibly due to non-carrier mediated diffusion [68] and/or higher levels of creatine transporter in endothelial cells of the choroid plexus [69].
For instance, it was shown that expression of Arabidopsis thaliana AtTIP1 1 and AtTIP1 2 genes in yeast cells decreased their survival rate in the presence of H2O2, while blocking this aquaporin-mediated diffusion alleviated the effect of H2O2 (Bienert et al. 2007).
The mechanistic details of this model must be revisited, given our recent identification of a protein-mediated diffusion barrier, which prevents the exchange of both membrane and soluble proteins between the stalk extension and the cell body.
The curve of the intra-particle diffusion model (Fig. 4) indicated the presence of multi-linear features, which confirmed the minor role of intra-particle diffusion of Cu and Zn from the surface of ESP to the inner walls of pores and the major role of film-mediated diffusion.
Our recent discovery of protein (StpABCD -mediated diffuStpABCD -mediatedch compartmentalize the stalk from the cell bodiffusion us to develop hypotheses regarding (1) the rationale barrierstalk architecture and (2) the physiological function of stalk lengthening during phosphate starvation.
In this study we explored cholesterol-mediated binding and diffusion of DNA origami structures on supported lipid bilayer membranes and utilized it to create hierarchical assemblies and arrays of such structures with sizes of several micrometers.
Vitreous body hyaluronic acid decreases histone-mediated toxicity by inhibiting diffusion of histones.
Sustained Ca2+ influx through ionotropic glutamate receptor-dependent calcium signaling increases GABAAR lateral diffusion, thereby causing the dispersal of synaptic GABAAR, while tonic mGluR-mediated IICR restrains the diffusion of GABAAR, thus increasing its synaptic density.
