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. …”

Theoretical insight into effect of cation–anion pairs on CO2 reduction on bismuth electrocatalysts by Sun Hee, Yoon

“…The adsorption energy (Eads) and work function (Wf) of the anions increases with decreasing anion size (i.e., Cl− > Br− > I−). On the other hand, the larger the cation size is, the higher is the Eads (i.e., Li+ < K+ < Cs+) but the lower is the Wf (i.e., Cs+ < K+ < Li+). …”

Spectrofluorometric investigations on the solvent effects on the photocyclization reaction of diclofenac by Abdulilah Dawoud, Bani-Yaseen

“…The solvent effects were qualitatively and quantitatively assessed employing various solvatochromic models, including multi-parameter linear regression analysis (MLRA). Interestingly, the MLRA results (R = 0.99) revealed that the photoconversion rate increases with increasing solvent polarizability (π*) and H-bond donor capability (α), whereas the rate decreases with increasing hydrogen-bond acceptor capability (β). …”

Enhancing oil removal from water using ferric oxide nanoparticles doped carbon nanotubes adsorbents by Fard, Ahmad Kayvani

“…The loading of Fe2O3 nanoparticles on the negative surface of CNT decreases the negative sign and magnitude of the zeta potential by overcoming the repulsive effects of the electrical double layers to allow the finely sized oil droplets to form larger droplets through coalescence. …”

Plasma volume variations in response to high intensity interval training in obese women: The influential role of menopausal status and age by Jabbour, Georges

“…For all women pre- and post-HIIT comparisons revealed significant differences in the extent of PV reduction at all two points (P < 0.01). Multiple linear regression analysis revealed that age was a significant contributor to the decreases in plasma volume (PV) observed both after warm-up and following the supramaximal cycling test - SCT (r = 0.44 and r = 0.57). …”

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. …”
