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. …”

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. …”

Mixed siliciclastic-carbonate-evaporite sedimentation in an arid eolian landscape: The Khor Al Adaid tide-dominated coastal embayment, Qatar by John M., Rivers

“…Three depositional sectors are delineated: 1) an energetic, linear, fault-controlled Entrance Channel into which the eolian dunes spill directly; 2) a relatively deep (up to 20 m) Outer Lagoon, interpreted to represent a flooded karst-collapse structure; and 3) a sprawling, low-energy, shallow (<2 m) Inner Lagoon occupying low-lying areas between deflated eolian dunes.Physical oceanographic modeling, integrating multi-seasonal current meter and tidal gage measurements, demonstrates tidal current flow velocities are relatively high in both the Entrance Channel and at the constricted entrance to the Inner Lagoon. …”

Electrical characteristics and density of states of thin-film transistors based on sol-gel derived ZnO channel layers with different annealing temperatures by Wang S.

“…We report on the fabrication and electrical characterization of bottom gate thin-film transistors (TFTs) based on a sol-gel derived ZnO channel layer. The effect of annealing of ZnO active channel layers on the electrical characteristics of the ZnO TFTs was systematically investigated. …”

Changes in expression of Kv7.5 and Kv7.2 channels in dorsal root ganglion neurons in the streptozotocin rat model of painful diabetic neuropathy by Laiche, Djouhri

“…We found 35 days post-STZ: (1) a significant decrease in Kv7.5-immunoreactivity in small (<30 μm) DRG neurons (both IB4 positive and IB4 negative) and medium-sized (30−40 μm) neurons, and (2) a significant increase in Kv7.2-immunoreactivity in small (<30 μm) neurons, and a non-significant increase in medium/large neurons. …”

Influence Of Surface Finish Parameters On Corrosion Of Zinc by Mourad, M. Y. [ممدوح درويش الديري]

“…Also, it was found that the increase in surface roughness has two connecting effects. The first leads to a decrease in corrosion potential due to a decrease in the cathodic surface area while the second leads to an increase in corrosion potential due to a decrease in the peak to valley distances of surface irregularities…”

Roadmap toward energy-positive upfront nitrogen removal process in baseload LNG plant by Mkacher, Hajer

“…The use of liquefied natural gas (LNG) has grown over the last decade owing to an increase in the global energy demand. This work presents a pioneering approach for rigorous simulation of an actual cold section of an LNG plant and provides a potential process optimization to achieve a higher production rate (PR) while reducing the specific power consumption (SPC). …”

Towards energy efficient and quality of service aware cell zooming in 5G wireless networks by Lateef, Hafiz Yasar

“…The exponential growth of mobile data traffic would lead to dense deployment of small base stations and eventually higher energy consumption in Fifth Generation (5G) wireless networks. We formulate a dynamic cell zooming and base stations sleep optimization algorithm for dense heterogeneous networks as a Linear Programming (LP) problem in order to not only minimize the system power consumption but also to guarantee the quality of service to end user. …”

Asymmetric effects of oil price shocks on the demand for money in Algeria by Amirouche, Chelghoum

“…This paper investigates the symmetric and asymmetric effects of real oil prices on real money demand in Algeria over the period 1999:Q1–2020:Q1. Using a linear autoregressive distributed lag model (ARDL), and a nonlinear autoregressive distributed lag model (NARDL), we find no evidence of a long-term relationship among the variables. …”

Enhancing the production of biogas through anaerobic co-digestion of agricultural waste and chemical pre-treatments by Almomani F.

“…The results revealed that the highest cumulative methane production (CMP) of 297.99 NL/kgVS can be generated by co-digestion of ASWs and CD at a ratio of 60:40. Further improvement was achieved via alkalinity treatment with 1.0 g of NaHCO3/gVS leading to decrease in lignin, cellulose, and hemicellulose contents of feedstock by 3.5%, 10.5% and 15.9%, respectively, converting them to soluble fractions and improving the CMP by 11.2–29.7% based on substrate quality. …”

Cultivating microalgae in desert conditions: Evaluation of the effect of light‐temperature summer conditions on the growth and metabolism of nannochloropsis qu130 by Jabri, Hareb Al

“…In the Qatar desert the temperature varies widely, typically between 10° and 45 °C There are also wide variations in light intensity, with values of over 1500 μmolhν.m−2s−1 in summer. A study of the effects of these thermal and light fluctuations is therefore essential for large‐scale outdoor production systems, especially during the summer when temperature and light fluctuations are at their highest. …”
