Hybrid shell microcapsules containing isophorone diisocyanate with high thermal and chemical stability for autonomous self-healing of epoxy coatings
(
John Wiley and Sons Inc.
, 2019 , Article)
Silica-polyurea/polyuretane hybrid shell microcapsules (MCs) loaded with isophorone diisocyanate (IPDI) with long shelf-life and high thermal and chemical stability are prepared via emulsification followed by interfacial ...
Desorption of chloramphenicol from ordered mesoporous carbon-alginate beads: Effects of operating parameters, and isotherm, kinetics, and regeneration studies
(
Elsevier Ltd
, 2021 , Article)
This study has investigated the desorption of an emerging contaminant, known as chloramphenicol (CPC), from ordered mesoporous carbon (OMC)-alginate beads. The effects of initial concentration, operating temperature, and ...

This research focus onto batch adsorption of nickel ions (Ni(II)) onto husk of Oryza sativa (HOS) from aqueous solution at room temperature. Several techniques such as Fourier transform infrared, scanning electron microscopy ...
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. ...
Development of a New Borax-Based Formulation for the Removal of Pyrite Scales
(
American Chemical Society
, 2020 , Article)
In the oil and gas industry, pyrite forms one of the most hardened scales in reservoirs, which hinders the flow of fluids. Consequently, this leads to blockage of the downhole tubular, formation damage, and complete shutdown ...
Solar thermochemical ZnO/ZnSO4 water splitting cycle for hydrogen production
(
Elsevier Ltd
, 2017 , Article)
In this paper, solar reactor efficiency analysis of the solar thermochemical two-step zinc oxide-zinc sulfate (ZnO-ZnSO4) water splitting cycle. In step-1, the ZnSO4 is thermally decomposed into ZnO, SO2, and O2 using solar ...
Thermodynamic evaluation of hydrazine assisted glycerol reforming for syngas production and coke inhibition
(
Elsevier Ltd
, 2018 , Article)
Thermodynamic investigation of glycerol reforming has been performed to study hydrogen production, carbon dioxide evolution and coke formation. Gibb's free energy direct minimization procedure was used to calculate the ...
Smart non-woven fiber mats with light-induced sensing capability
