Alumina-supported palladium and palladium/copper catalysts: Characterization and use for selective hydrogenation of 1,3-butadiene
… a considerable economic incentive to improve the currently employed palladium-based catalysts. The purpose of this research has been to investigate the effects of adding copper to alumina-supported palladium to enhance the selectivity of palladium for butadiene hydrogenation. 1,3-Butadiene …

Removal of Per- and Poly-fluoroalkyl Substances (PFAS) from Water: A Computational Approach
… density functional theory (DFT) calculations with data-driven machine learning (ML) approaches. DFT investigations reveal that PFAS adsorption on transition metal surfaces is primarily governed by interactions between functional head groups and the adsorbent, with protonated sulfonic …

Applications of lattice dynamics theory : calculating vibrational entropy in alloys and dielectric losses in ceramics
… ordered-L12 and disordered phases in the Au3Cu, Cu3Au, Cu3Pd, Pd3Cu, Cu3Pt, Au3Pd, and Pd3Au systems are calculated. This study was done using first-principles energy calculations and the supercell method. Calculated values of ASÊ»rder-disorder ranged between -0.05 - 0.07 kB. Length-dependent …

Study of diffusion damage in the copper-nickel system
Study of prolonged diffusion in Cu-Au and Cu-Pd systems has revealed that the diffusion generated misorientations tend to mend themselves because of reduced concentration gradients. Previous studies of the Cu-Ni system in which a 8.0 micron nickel plated single crystal copper was diffused up to 5 …

Novel electrode fabrication and reactor design for electrocatalytic nitrate and nitrite reduction in drinking water treatment
… water sources and posing health risks to humans. Current go-to technologies like ion exchange (IX) and reverse osmosis (RO) produce concentrated NO₃⁻ brines that require further treatment and/or disposal, and alternatives like catalytic reduction suffer from gas-liquid mass transfer limitations …

Kinetics of Buffer-Layer-Assisted Nanostructure Growth
… or the particle or both. In order to circumvent these obstacles, the technique of buffer-layer-assisted growth (BLAG) was introduced by our research group during the 1990’s. In this technique, physical vapor deposition is done on a thin film buffer of condensed rare gas solid, where …

Photoelectrochemical and Chemoenzymatic Reforming for Sustainable Fuel Production
… atmospheric greenhouse gas concentrations and accumulation of persistent waste have attracted the attention of scientists, policy-makers and global organisations to come up with effective and expeditious solutions to address these challenges. In this context, the development of sustainable …

Preparation, Characterization and Evaluation of Bimetallic Catalysts Prepared by Electroless Deposition Methods
… and catalyst composition very difficult. Electroless deposition (ED) is one of the preparative methodologies that provides a way to catalytically deposit in a controlled manner, a second metal only on the surface of a pre-existing metallic surface (i.e., not on support). Thus, …
