Self-Standing Pd-Based Nanostructures for Electrocatalytic CO Oxidation: Do Nanocatalyst Shape and Electrolyte pH Matter?
( Multidisciplinary Digital Publishing Institute (MDPI) , 2023 , Article)Tailoring the shape of Pd nanocrystals is one of the main ways to enhance catalytic activity; however, the effect of shapes and electrolyte pH on carbon monoxide oxidation (COOxid) is not highlighted enough. This article ... -
Settling behavior of fine cuttings in fiber-containing polyanionic fluids for drilling and hole cleaning application
( Elsevier B.V. , 2021 , Article)For efficient drilling operations, cuttings transport within the oil and gas wellbore is fundamental. Inadequate hole cleaning results in many problems including reduced rate of penetration, increased torque, bit wearing, ... -
Simulation study of Schottky contact based single Si wire solar cell
( IEEE , 2014 , Conference Paper)We model single silicon nanowire (SiNW) solar cells with dissimilar work function metal contacts. Both short circuit current (ISC) and open circuit voltage (VOC) have been investigated. Effects of nanowire dimension, ... -
Simultaneous removal of Congo red and cadmium (II) from aqueous solutions using graphene oxide–silica composite as a multifunctional adsorbent
( Chinese Academy of Sciences , 2020 , Article)Graphene oxide is a very high capacity adsorbent due to its functional groups and π−π interactions with other compounds. Adsorption capacity of graphene oxide, however, can be further enhanced by having synergistic effects ... -
Simultaneous treatment of reject brine and capture of carbon dioxide: A comprehensive review
( Elsevier B.V. , 2020 , Article Review)The ongoing expansion of industries results in the increased emission of various pollutants into the environment, contributing to the rapid deterioration of air, water, and soil quality. Notable pollutants addressed in ... -
Size-And Wavelength-Dependent Two-Photon Absorption Cross-Section of CsPbBr3 Perovskite Quantum Dots
( American Chemical Society , 2017 , Article)All-inorganic colloidal perovskite quantum dots (QDs) based on cesium, lead, and halide have recently emerged as promising light emitting materials. CsPbBr3 QDs have also been demonstrated as stable two-photon-pumped lasing ... -
Solar photocatalytic degradation of 2-chlorophenol with ZnO nanoparticles: optimisation with D-optimal design and study of intermediate mechanisms
