Prevention of gallium arsenide photocorrosion by an epoxy adhesion layer by Alqaradawi, Siham Y.

“…The room temperature electrical conductivity of the epoxy films increased from 10−8 to 10−4Ω−1cm−1 due to gold impregnation. Enhancement of the photocurrent due to gold impregnation is attributed due to better conduction of the photogenerated holes into the electrolyte, also due to activating the adsorption of electrolyte ions.Several parameters are studied with the objective of determining the stability of epoxy films: these are continuous current–voltage (I–E) scans, prolonged illumination, weight changes and surface topography by scanning electron microscopy. …”

Microbial electrosynthesis feasibility evaluation at high bicarbonate concentrations with enriched homoacetogenic biocathode by Gunda, Mohanakrishna

“…The acetate production rate was found to increase with the increase in the bicarbonate concentration and evidenced a maximum production rate of 260 mg/L d−1 (15 g HCO3−/L). On the contrary, carbon conversion efficiency decreased with the increase in the bicarbonate concentration, which evidenced a maximum at 2.5 g HCO3−/L (90.16%). …”

Ratings of perceived exertion misclassify intensities for sedentary older adults during graded cycling test: Effect of supramaximal high-intensity interval training by Jabbour G.

“…The intervention elicited physiological changes at rest and submaximal intensities, while no improvements were noted for both groups in aerobic fitness (i.e., V?O2peak). For both groups, RPE decreases with SCE at 10 min following graded test correlated significantly to V?…”

Effect of Fluid Viscosity and Fiber Length on the Performance of Fibrous Fluid in Horizontal Well Cleanout by Mendez, Michael

“…Various methods have been developed to improve hole cleaning, but their effectiveness decreases as the wellbore inclination increases. One way to solve this issue is to add fibers to the drilling fluid and reduce the settling velocity of the solids to improve the fluid's lifting capacity. …”

Active Power Filtering Solution for Improving Power Quality in Cold Ironed Electric Ships by Rahman, Syed

“…However, there are some concerns with the ability to charge batteries during long voyages and the weight addition that large batteries would bring. One way to reduce GHG emissions in port is by cold ironing a ship or plugging in a ship to an onshore power source instead of using onboard diesel generators when ships are at port. …”
