Molecular dynamics of CH4/CO2 on calcite for enhancing gas recovery by Carchini, Giuliano

“…In fact, from pure methane to 20/80 CO2/CH4, methane adsorption increases linearly with pressure. For gas mixtures with a CO2 concentration higher than 40%, higher pressure has less impact on methane adsorption. …”

Investigation of Spatiotemporal Variability of Microplastics in Qatar's Cstal Environment by Ben-Hamadou, Radhouane

“…Adsorbed PCBs and PAHs concentration showed a steady decrease with time, suggesting that contaminated pellets ending in the marine environment release their adsorbed contaminants in less contaminated seawaters revealing a complex OPs dynamic between plastics an seawater as a function of differential concentrations of pollutants and environmental conditions. …”

Experimental results and modelling of corrosion-damaged concrete beams strengthened with externally-bonded composites by Elghazy M.

“…The FE models were able to capture the non-linear behavior of the strengthened beams. The interfacial bond stress-slip models at the fabric/matrix and composite/concrete interfaces and the number of composite layers had the most significant impact on the predicted response of the strengthened beams whereas the corrosion level, modeled as a reduction in the steel reinforcement cross-section, showed a slight effect on their performance. …”

Modelling the asymmetric responses of price level to oil price changes in Qatar by Mrabet, Zouhair

“…Moreover, we find that price responses to negative changes in oil price is greater than its response to positive changes. Given Qatar's economic features, a decrease in oil price could cause lower imports and production prices and consequently a substantial influence on domestic prices level. …”

High temperature thermal stability of innovative nanostructured thin coatings for advanced tooling by Cabibbo, Marcello

“…The main problem with steel, isthat itexhibits a relatively low hardness (below 10 GPa) which strongly decreases upon annealing above about 600 K.Thus, the majority of modern tools are nowadays coated with hard coatings that increase the hardness, decrease the coefficient of friction and protect the tools against oxidation. …”

Modification of Pd/CeO2 catalyst by Atomic Layer Deposition of ZrO2 by Onn, Tzia Ming

“…Calcination of the unmodified Pd/CeO2, prepared by precipitation of aqueous Ce(NO3)3 solutions, with Pd added by impregnation, caused a large decrease in surface area and an increase in crystallite size between 673 K and 1073 K; however, catalysts modified by 0.4 nm ZrO2 films showed no change in either surface area or CeO2 crystallite size upon calcination to 1073 K. …”
