A new chelating sorbent was synthesized by covalently linking carbon nano-fiber with ion exchange polyurethane foam (CNF-PUFIX). CNF-PUFIX was characterized using different tools e.g. elemental analysis, IR spectrum and SEM. The functional groups of PUF have disappeared. The phenolic, carboxylic, quaternary ammonium salt and tertiary amine groups are detected in the CNF-PUFIX. The sorption prop...

Binary nano-composites of Pt and nano-carbon (NC) and Pt and multiwalled carbon nanotube (MWCNT) have been prepared with varied compositions ranging between 20 and 80wt% Pt and investigated them as electrocatalysts for methanol oxidation. The study shows that with the increase in wt% of NC, the apparent electro-catalytic activity of the composite catalyst increases initially, reaches maximum at...

High-Z nano materials have been previously shown to increase the amount of dose deposition within the tumour due to an increase in secondary electrons. This study evaluates the effects of high-Z nano materials in combination with protons, and the impact of proton energy, nanoparticle material and concentration. These effects were studied in silico through Monte Carlo simulation and experimental...

Green hydrogen produced by water electrolysis in combination with renewable energy is expected to become a key enabler for decarbonization of and transportation sectors as well hard-to-abate industries, contributing the achievement carbon neutrality. Compared conventional alkaline technology, proton exchange membrane (PEMWE) possesses many advantages green production, but currently relies heavi...

Hydroquinone (HQ) was electrochemically measured using convolutive cyclic voltammetry and differential pulse (DPV) on a nano-architecture mesoporous platinum film grown from hexagonal liquid crystalline template of C16EO8 surfactant in 1.0 mol/l HClO4. The HQ voltammograms produced one oxidative peak the forward sweep potential reductive reverse sweep. effect concentration investigated differen...

Abstract In the present investigations platinum nano-particles in range of ≤ 20 nm were carefully ball milled with nominal composition hollow carbon nano-spheres to apply as a softener ductile mechanical tensile promoter for 2212-PBSCCO superconductor. The samples general formula Pb 1+x (HCNs/Pt) x BiSr 2 CaCu O 8 where (x = 0.1,0.2 and 0.4 mol) synthesized via solid state reaction route certai...
