Hydrogenation of benzoic acid using monoand bimetallic catalyst of Ru, Pd, Co, and Re yielded different products. It was observed that 5% Ru/C was an active catalyst for hydrogenation of both aromatic ring and carboxylic group, while Pd/C catalyst hydrogenated only aromatic ring. Ru-Sn/Al2O3 is a chemoselective catalyst for hydrogenation of –COOH group of benzoic acid.

Magnetic parameters of magnetosomes inside the bacteria MSR-1, LBB-42, AMB-1, SP-1, BB-1, and SO-1 strains genus Magnetospirillum fixed by 5% formalin in nutrient medium were estimated measurements nonlinear longitudinal response to a weak ac magnetic field (NLR-M2) at room temperature. For AMB-1 strains, electron resonance (EMR) spectra with special X-band spectrometer for wide-line registrati...

a green, efficient and selective approach for the oxidation of sulfides to sulfoxides and sulfones with uhp at room temperature is reported. the reaction is performed in the presence of vanadia catalyst supported on mesocellular silica foam (mcf) with a v content ranging from 2% to 10% as heterogeneous and reusable catalyst. the structural and textural characterization of this catalyst were don...

Increase surface area of the 3M-patented, nanostructured, thin-film catalyst support system consistent with high-volume manufacturing process. Develop anode catalyst compositions and structures with higher reformate tolerance and/or a non-precious metal replacement for Ru by using a catalyst deposition process that easily generates new compositions and structures. Investigate catalyst compositi...

The goal of the present thesis is to treat a wide diversity of problems in magnets by the tools of the modern computational micromagnetism. As an application of the self-elaborated numerical techniques this thesis includes a phenomenological description of magnetic phenomena in magnets with different geometry on nanoscale (part I) and in non-centrosymmetric magnets with chiral Dzyaloshinskii-Mo...

For the development of highly active and robust catalysts for dehydrogenation of ethylbenzene (EBDH) to produce styrene; an important monomer for polystyrene production, perovskite-type oxides were applied to the reaction. Controlling the mobility of lattice oxygen by changing the structure of Ba1 - x SrxFe y Mn1 - y O3 - δ (0 ≤ x ≤ 1, 0.2 ≤ y ≤ 0.8), perovskite catalyst showed higher activity ...

Biodiesel production is worthy of continued study and optimization of production procedures due to its environmentally beneficial attributes and its renewable nature. Heterogeneous transesterification is considered to be a green process. The process requires neither catalyst recovery nor aqueous treatment steps and very high yields of methyl esters can be obtained, close to the theoretical valu...

bis-(l-tyrosinato)copper(ii) was reacted with 3-(chloropropyl)-trimethoxysilane functionalized silica that has infused magnetite to yield a magnetically separable catalyst in which the copper carboxylate is covalently linked to the silica matrix through the silane linkage. the immobilized catalyst has been characterized by spectroscopic studies (such as ft-ir, epr, magnetic measurement, sem) an...
