TL;DR: In this article, Monte Carlo simulations of disordered silicon-carbon alloys have been used to obtain detailed information about the structural and compositional short-range order as well as the energetics.
Abstract: Monte Carlo simulations, based on an empirical potential approach, have yielded detailed information about the structural and compositional short-range order as well as the energetics of disordered silicon-carbon alloys. It is found that the network of the amorphous phase deviates from an ideal tetrahedral geometry because a considerable number of carbon atoms are threefold coordinated, especially in the carbon-rich samples. Silicon, on the other hand, retains a coordination number of four. There is no phase separation. Comparing the present results with experimental observations, it is speculated that hydrogenation will promote tetrahedral carbon coordination

TL;DR: The gas phase helium (i) photoelectron spectra of the actinide tetrahalides UF4, ThF 4, UCl 4, and ThCl 4 have been recorded as discussed by the authors.
Abstract: The gas phase helium (i) photoelectron spectra of the actinide tetrahalides UF4, ThF4, UCl4, and ThCl4 have been recorded. The spectra have been interpreted with the aid of nonrelativistic multiple‐scattering SCF‐Xα calculations and are consistent with an effective tetrahedral geometry for these molecules in the gas phase. Both the calculations and the spectra indicate that the 5f electrons in UF4 and UCl4 are essentially localized on the central metal.
