The uses cyclic voltammetry, in situ Raman spectra, polarization curves, and FTIR analysis determine optimal composition gold palladium enhancing process. results demonstrate potential utilizing as a feedstock producing sustainable energy sources. Pd75Au25/ATO electrode exhi...

Palladium doped iron rhodium is a magnetic material of significant interest for it's close to room temperature magnetostructural phase transition from antiferromagnetic (AF) to ferromagnetic (FM) ordering. Here we report on the peculiarities of the magnetization distribution in thin films of FeRh(Pd) probed by Polarized Neutron Reflectometry. Remarkably, we've found thin interfacial regions wit...

Semiconducting molybdenum disulfphide has emerged as an attractive material for novel nanoscale optoelectronic devices due to its reduced dimensionality and large direct bandgap. Since optoelectronic devices require electron-hole generation/recombination, it is important to be able to fabricate ambipolar transistors to investigate charge transport both in the conduction band and in the valence ...

A method for rapid screening of photocatalysts employing a form of scanning electrochemical microscopy (SECM) is described. A piezoelectric dispenser was used to deposit arrays composed of approximately 300-microm-size photocatalyst spots with different compositions onto conducting glass, fluorine-doped tin oxide substrate. The scanning tip of the SECM was replaced by a fiber optic connected to...

Abstract: This paper presents a highly sensitive fiber-optic oxygen sensor. The sensor was fabricated using palladium (II) meso-tetrakis (pentafluorophenyl) porphyrin (PdTFPP) and porous silica nanoparticles embedded in a tetraethylorthosilane (TEOS)/n-octyl-triethoxysilane (Octyl-triEOS) composite xerogel present as a coating on the end of the fiber. Sensitivity is quantified in terms of the r...

SLAC-PUB-1667 (Rev.) November 1975 Revised May 1976 (1) ELECTROLYTIC CONDUCTIVITY DETECTOR FOR TRACE ANALYSIS OF HZ, HD, D2, AND NEON IN HYDROGEN AND DEUTERIUM” E. L. Garwin and A. Roder Stanford Linear Accelerator Center Stanford University, Stanford, California 94305 A gas chromatograph has been developed to detect traces of H2, HD, D2, and neon in hydrogen or deuterium. It uses a stainless s...

A novel class of dibenzo-fused 1,9-diaza-9a-boraphenalenes featuring zigzag edges with a nitrogen-boron-nitrogen bonding pattern named NBN-dibenzophenalenes (NBN-DBPs) has been synthesized. Alternating nitrogen and boron atoms impart high chemical stability to these zigzag-edged polycyclic aromatic hydrocarbons (PAHs), and this motif even allows for postsynthetic modifications, as demonstrated ...

Renewable methanol, obtained from CO2 and hydrogen provided renewable energy, was proposed to close the loop. In industry, methanol synthesis using catalyst CuO/ZnO/Al2O3 occurs at a high pressure. We intend make certain modification on traditional work lower pressure, maintaining selectivity. Therefore, three heterogeneous catalysts were synthesized by coprecipitation improve activity selectiv...

Abstract Anode processes on SnO 2 ‐based electrodes in low‐concentrated NaCl solutions have been investigated. The current‐voltage curves for 25 tin oxide anodes doped with various amounts of platinum group metals 0.5 M NaClO 4 and + analyzed. correlation criterion between the catalytic activity coating relation to reaction synthesis NaClO, 3 from solutions, oxygen evolution overpotential was f...

Due to the high cost of polymer electrolyte fuel cells (PEFCs), replacing platinum (Pt) with some inexpensive metal was carried out. Here, we deposited palladium nanoparticles (Pd-NPs) on nanoporous carbon (NC) after wrapping by poly[2,2'-(2,6-pyridine)-5,5'-bibenzimidazole] (PyPBI) doped with phosphoric acid (PA) and the Pd-NPs size was successfully controlled by varying the weight ratio betwe...
