TL;DR: In this paper, a modified version of Hillert's grain growth model is presented, in which two distinct types of grains are present, and anisotropic grain boundary energies are modeled by assigning a higher energy to boundaries between like type than to boundaries of unlike type.

TL;DR: In this article, the catalytic behavior of silica-supported Group VIII metals in the COH2 synthesis reaction has been determined and compared to that of alumina-supported metals, and the most recent values for CO heats of adsorption on these metal surfaces were utilized to obtain this volcano plot and verify the correlation between activity and ΔH(ad) observed earlier with aluminasupported metals.

TL;DR: In this article, a number of new semiconductors with smaller band gaps, such as Fe2O3, WO3 and p-GaP, are studied for hydrogen production in sunlight.

TL;DR: In this article, coal was converted to benzene-soluble, liquid products through a reaction path which appears to involve thermal cleavage of chemical bonds in the coal (so-called depolymerization), and free radicals formed pyrolytically were stabilized in the early stages by autogenous hydrogen transfer, and in later stages by abstraction of hydrogen from the hydrogen-donating tetralin.

TL;DR: In this paper, the microstructure of polycrystalline materials is digitized by dividing the polycrystaline material into small volume elements and storing the spatial location and crystallographic orientation of each element.
Abstract: Computer modelling has been carried out to study normal grain growth in three dimensions. The approach consists of digitizing the microstructure by dividing the polycrystalline material into small volume elements and storing the spatial location and crystallographic orientation of each element. An energy is assigned between each element and its neighbours, such that neighbours having unlike orientations provide weaker bonding than neighbours of like orientations. The annealing treatment during which grain growth occurs is simulated using a Monte Carlo technique in which elements are selected at random and thermally activated transitions to other orientations are attempted. With time, the system evolves so as to reduce the total grain interface area. The microstructures produced are in good correspondence to observations of pure metals and ceramics which have undergone grain growth. Power-law kinetics ([Rbar] = ct n) are observed, with a growth exponent in three dimensions of n = 0·48 ±0·04 in the...
