CH₄ as the paramount ingredient of natural gas plays an eminent role in C1 chemistry. CH₄ catalytically converted to syngas is a significant route to transmute methane into high value-added chemicals. Moreover, the CO/CO₂ methanation reaction is one of the potent technologies for CO₂ valorization and the coal-derived natural gas production process. Due to the high thermal stability and high ext...

The chemical reduction progression behaviour of transition metals (Mo, Zr, W, Ce, and Co) doped on NiO was studied using temperature programmed (TPR) analysis. A wet impregnation method applied to synthesise the series catalysts. progress catalysts attained by a reductant gas at concentration 40% v/v CO/N2. X-ray diffraction (XRD) employed determine composition reduced phases. Undoped 384℃ obta...

BACKGROUND An in-vitro setup was established in order to determine a) the diffusion activities of eight otic preparations (Aurizon®, Eas Otic®, Epi Otic®, Otifree®, Otomax®, Panolog®, Posatex®, Surolan®) through synthetic cerumen, and b) the ceruminolytic capacity and impregnation effects of these products. The main lipid classes of canine cerumen produced with moderate, non-purulent otitis ext...

Nanocrystalline ceria has been considered as support for carbon monoxide preferentially oxidation. In this study ceria was prepared by precipitation method and the effects of preparation conditions, such as pH of solution (8-10), aging time (1-12 hr), drying temperature (80-120 °C), calcination time (2-6 hr) and temperature (400-600 °C) were investigated on ceria synthesized powders properties....

Leptospires are difficult to stain with the usual bacterial stains; many different stains have been proposed, most of which are designed for staining of tissue sections. Silver stains that are available for smear preparations yield variable, unreliable results. Staining of bacterial flagella is often avoided because of difficulties involved. There exists a need for a simple technique which does...

Bimetallic AuPd nanoparticles supported on TiO2 are known to catalyze the reduction of NO with CO. Here, we investigated effects addition lanthanum oxide a AuPd/TiO2 catalyst particle size 2.1–2.2 nm. The La2O3 enhanced catalytic activity; for example, at 250 °C, there was 40.9% conversion and 49.3% N2-selectivity AuPd/TiO2, 100% AuPd-La (1:1)/TiO2. temperature requiring dropped from 400 °C 200...
