Flexural behavior of reinforced concrete beams prepared with treated Wastewater, recycled concrete Aggregates, and fly ash by Abushanab, Abdelrahman

“…Utilizing treated domestic wastewater (TWW), recycled concrete aggregates (RCA), and fly ash (FA) in reinforced concrete (RC) structures is of great interest from a sustainability perspective. In this study, four RC beams (180 x 250 x 2000 mm) were fabricated and tested under a four-point bend flexure until failure. …”

Combined influence of temperature and flow rate of feeds on the performance of forward osmosis by Hawari, Alaa H.

“…It was also found that when increasing the draw solution (DS) temperature from 20 °C to 26 °C the flux increased linearly and then started decreasing when temperature increased over 26 °C due to the development of a temperature gradient. …”

Impacts of rural tourism-driven land use change on ecosystems services provision in Erhai Lake Basin, China by Li, Jinghui

“…With these land changes, ecosystem services also changed greatly, to the detriment of ELB as a whole and especially the lakeside zone. By 2015, soil retention had decreased and nitrogen and soil export had increased, compared with the levels in 2000, while there was only a slight fluctuation in carbon storage and water yield. …”

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). …”
