WorldView-3 mapping of Tarmat deposits of the Ras Rakan Island, Northern Coast of Qatar: Environmental perspective
(
Elsevier
, 2021 , Article)
This study characterizes the spectral behavior of tarmats and maps the tarmat deposits found along the coast of Ras Rakan Island off Qatar using WorldView-3 (WV-3) sensor data. The laboratory spectra of tar materials showed ...
Fabrication of H2S sensitive gas sensors formed of SnO2–Fe2O3 composite nanoparticles
(
Elsevier B.V.
, 2021 , Article)
Nanocomposites of metal oxide are considered promising candidates for developing novel gas sensors of exceptional performance. Composite SnO2–Fe2O3 nanoparticles are produced in this work by a modified sole-gel method, and ...
Dual cationic modified high Ni-low co layered oxide cathode with a heteroepitaxial interface for high energy-density lithium-ion batteries
(
Elsevier
, 2021 , Article)
Lithium-ion batteries (LIBs) with high energy density, safety with longer service life, cost-effectiveness, and superior cycling stability is a demand to achieve the driving range of 300 miles per charge in electric vehicles ...
Thermo-osmosis-Coupled Thermally Regenerative Electrochemical Cycle for Efficient Lithium Extraction
(
American Chemical Society
, 2021 , Article)
Lithium (Li) production based on the soda evaporation process is time-consuming and unsustainable. The emerging electrochemical Li extraction is time-efficient but requires high-concentration Li sources and significant ...
Electrocatalytic activity of nanoparticulate TiO2 coated onto Ta-doped IrO2/Ti substrates: Effects of the TiO2 overlayer thickness
(
Elsevier
, 2021 , Article)
The trade-off between short-term efficiency and long-term durability in electrocatalysis has always been a tough choice. This study examines the electrocatalytic activity of double-layered oxide electrodes comprising a ...
Electrocatalytic arsenite oxidation in bicarbonate solutions combined with CO2 reduction to formate
(
Elsevier
, 2020 , Article)
Sunlight-driven water-energy nexus technologies are receiving increasing attention. This study presents a hybrid electrochemical system that catalyzes the oxidation of As(III) to As(V) with a nanoparticulate TiO2 electrocatalyst ...
Control of the antagonistic effects of heat-assisted chlorine oxidative degradation on pressure retarded osmosis thin film composite membrane surface
(
Elsevier
, 2021 , Article)
During pressure retarded osmosis (PRO) operation, thin film composite (TFC) membranes are continuously exposed to chemicals present in the stream that can deteriorate the membrane's selective layer with exposure time. ...
In Situ-Generated Reactive Oxygen Species in Precharged Titania and Tungsten Trioxide Composite Catalyst Membrane Filters: Application to As(III) Oxidation in the Absence of Irradiation
(
American Chemical Society (ACS)
, 2020 , Article)
This study demonstrates that in situ-generated reactive oxygen species (ROSs) in prephotocharged TiO2 and WO3 (TW) composite particle-embedded inorganic membrane filters oxidize arsenite (As(III)) into arsenate (As(V)) ...
Facile Electrochemical Synthesis of Highly Efficient Copper-Cobalt Oxide Nanostructures for Oxygen Evolution Reactions
(
Electrochemical Society
, 2020 , Article)
Nanostructured copper-cobalt oxide (CuxCo3-xO4, CCO) electrodes are grown directly on conducting substrates via electrochemical deposition; then, various factors (e.g., oxygen vacancies, electrochemically active surface ...
Electrocatalytic arsenite oxidation using iron oxyhydroxide polymorphs (α-, β-, and γ-FeOOH) in aqueous bicarbonate solution
(
Elsevier
, 2020 , Article)
α-, β-, and γ-FeOOH polymorphs have been synthesized and used for electrocatalytic As(III) oxidation into less toxic As(V) in aqueous bicarbonate solution. As-synthesized FeOOH electrodes exhibit unique crystalline structures ...
