Engineered porous Co–Ni alloy on carbon cloth as an efficient bifunctional electrocatalyst for glucose electrolysis in alkaline environment

, 2020
Toward water splitting, the cell voltage is limited by the sluggish anodic oxygen evolution reaction (OER), requiring a much higher overpotential than cathodic hydrogen evolution reaction (HER).

Quantitative phase analysis of slag hydrating in an alkaline environment

, 2020
An X-ray diffraction (XRD)-based evaluation of the crystalline and amorphous phases in slag hydrating in an alkaline environment is presented. A method is developed for the quantification of the amorphous phases present in hydrating slag in a sodium ...

Selenium biomethylation in an Alkaline, saline environment

Water Research, 1991
Abstract Biomethylation of Se in evaporation pond water was studied and optimized in laboratory-incubated mesocosms. Methylating microorganisms were present in all pond waters collected from the San Joaquin Valley, Calif. and were inhibited by bactericides (10 mg 1−1 crystal violet, 100 mg 1−1 penicillin G, and a 1:1 mixture of 50 mg 1−1 penicillin G

Isopranylglycerol diethers in non-alkaline evaporitic environments

Geochimica et Cosmochimica Acta, 1993
Abstract Gas chromatographic-mass spectrometric analyses of Tertiary and recent halite samples using high-temperature gas Chromatographic columns have shown that O-phytanyl-O-sesterterpanylglycerol and bis-O-phytanylglycerol are common constituents in halites deposited in non-alkaline systems.

Behavior of Basalt Fibers in an Alkaline Environment

Solid State Phenomena, 2022
The article presents experimental studies of the composite binders modification with basalt fibers waste. The introductory part provides studies overview of basalt fibers resistance in various aggressive environments. It was revealed that the most aggressive environment in relation to basalt fibers and other products based on them is alkaline. Also, it

Lamellar platinum–rhodium aerogels with superior electrocatalytic performance for both hydrogen oxidation and evolution reaction in alkaline environment

Journal of Power Sources, 2019
Hydrogen oxidation and evolution reactions (HOR and HER) in alkaline media are very kinetically sluggish, which becomes one of major barriers for the breakthrough of anion exchange membrane fuel cells.

Alkaline, Evaporative Environment

1989
Alkaline and evaporative sedimentation usually corresponds to lacustrine or restricted marine environments, characterized by the active formation of carbonate or saline minerals. In Quaternary and present-day sediments, these environments display mainly detrital clay suites, as documented by most lakes, coastal marshes, lagoons, and basins (4.4.1 ...
