In Table I, the values of the equilibrium separation ${d}_{\mathrm{eq}}$ for the graphene on Al, Ag, Cu, and Au surfaces are erroneously taken from those obtained by Khomyakov et al. [Phys. Rev. B 79, 195425 (2009)]. Our results for these surfaces, which are 3.49, 3.35, 3.31, and 3.35 \AA{}, respectively, are slightly…

Thermodynamic data are essential for understanding and evaluating geochemical processes, as by speciation-solubility calculations, reaction-path modeling, or reactive transport simulation. These data are required to evaluate both equilibrium states and the kinetic approach to such states (via the affinity term or its…
Historically, the GW approach was put forward by Hedin as the simplest approximation to the so-called Hedin equations. In Section 2, we will derive these Hedin equations from a Feynman-diagrammatical point of view. Section 3.1 shows how GW arises as an approximation to the Hedin equations. In Section 3.2, we briefly p…
This thesis has presented the results and findings of a study carried out into the effects \nof fibre pre-stressing on the impact performance of composite laminates. Fibre prestress \nhas been explained as a way of mechanically altering the internal residual stress \nstate of a composite, which typically is a result o…
Silicon nitride (Si3N4) is one of the most attractive materials for wear applications because it has excellent wear resistance and offers advantages such as light weight, higher strength and toughness, and good corrosion resistance. In 1984, Materials Div., Toshiba Corp. (today, Toshiba Materials Co., Ltd.) and Koyo S…

We describe procedures to obtain the electronic structure of disordered systems using either tight binding like models or quite directly from ab inito density functional band structure calculations. The band structure is calculated using super cells much larger than those containing a single minority component atom. W…

Pressure dependence of Extended X-ray Absorption Fine Structure (EXAFS) cumulants of silicon and germanium have been investigated using the statistical moment method (SMM). Analytical expressions of the first and second cumulants of silicon and germanium have been derived. The equations of states for silicon and germa…

Abstract Mixed Ce—W oxide catalysts (Ce2WOx, CeWOx, CeW2Ox) are prepared by homogeneous precipitation from aqueous solutions of Ce(NO3)3, (NH4)10W12O41, and (COOH)2 using urea (90 °C, 12 h) followed by calcination in air (500 °C, 5 h).

The dehydration of ethyl alcohol in atmospheric isothermal vapor phase to produce both ethylene and ether was studied in fixed bed reactor (2.54 cm inside diameter and 110 cm height). Two temperature ranges were used according to catalyst type, these are 250-350 0C for both alumina and zeolites (4A and 5A) and 90-120…
