Carboxylated alginate hydrogel beads for methylene blue removal: Formulation, kinetic and isothermal studies
( Desalination Publications , 2019 , Article)In this study, carboxylated alginate beads for methylene blue (MB) removal have developed, and the formulation conditions such as alginate concentration, calcium chloride concentration, cross-linking temperature, and beads ... -
Concurrent adsorption of cationic and anionic dyes from environmental water on amine functionalized carbon
( IWA Publishing , 2020 , Article)Amine functionalized carbon (AFC) was synthesized from raw oil fly ash and later utilized it for simultaneous removal of methyl orange (MO) and rhodamine 6G (Rh6G) pollutant dyes from aqueous medium. AFC was analyzed through ... -
Effects of experimental warming on soil respiration and biomass in Quercus variabilis Blume and Pinus densiflora Sieb. et Zucc. seedlings
( Springer-Verlag France , 2016 , Article)Key message: In the open-field warming experiment using infrared heaters, 3C warming affected soil respiration more in the deciduousQuercus variabilisBlume plot than in the evergreenPinus densifloraSieb. et Zucc. plot, but ... -
Highly active, durable and pH-universal hybrid oxide nanocrystals for efficient oxygen evolution
( Royal Society of Chemistry , 2017 , Article)The development of an active, durable, and low-cost catalyst remains hitherto a grand challenge in energy conversion technologies. Herein, hybrid Ptx-NiMnO3 nanocrystals (NCs) (x = 0.1, 0.5, and 1.0 mM) were synthesized ... -
Prevention of barite sag in water-based drilling fluids by a urea-based additive for drilling deep formations
( MDPI , 2020 , Article)Barite sag is a challenging phenomenon encountered in deep drilling with barite-weighted fluids and associated with fluid stability. It can take place in vertical and directional wells, whether in dynamic or static conditions. ... -
Pyrite-scale removal using glutamic diacetic acid: A theoretical and experimental investigation
( Society of Petroleum Engineers (SPE) , 2021 , Article)Iron sulfide scale causes major losses in both upstream and downstream sectors of the hydrocarbon industry. Pyrite is one of the most-difficult forms of iron sulfide scale from a removal point of view. Inorganic acids such ...
