Structural Effects of Tungsten Oxide Electro-Catalyst Towards High Stable CO Tolerance Mechanism

the effects of high non fibrous carbohydrates diet on milk production, inflammation and molecular mechanism of innate immunity in lactating dairy cows

پژوهش حاضر با هدف بررسی اثر جیره حاوی کربوهیدراتهای غیرالیافی زیاد و بروز التهاب در گاوهای شیرده در دو آزمایش جداگانه انجام شد. در آزمایش اول 20 رأس گاو مبتلا به ورم پستان از دو گروه کم تولید و پرتولید (هر کدام 10 رأس) و 20 رأس گاو سالم از دو گروه کم تولید و پرتولید (هر کدام 10 رأس) انتخاب شدند. همه گاوها در دوره دوم و یا سوم شیردهی و در روزهای 80-120 پس از زایش بودند. میانگین تولید شیر در گروه...

Structural and mechanical properties of nanostructured tungsten oxide thin films

This study presents structural and mechanical properties of WO3 thin films deposited on glass substrates at different temperatures by radio frequency reactive magnetron sputtering. WO3 films deposited at temperatures up to 200uC are found as amorphous, but crystalline at 300 and 400uC. Chemical analysis reveals the overstoichiometry of the films. The diffusion of sodium ions from glass substrat...

Effects of Excess Cobalt Oxide Nanocrystallites on LaCoO3 Catalyst on Lowering the Light off Temperature of CO and Hydrocarbons Oxidation

Catalysts with the formula of LaCo(1+x)O(3+δ), where 0 ≤ x ≤ 1, were studied for oxidation of CO and C2H6 in a synthetic exhaust gas, comprising 6.0 % CO and 0.2 % C2H6 in Ar. Ethane was selected as a model for hydrocarbons in the exhaust gas. The performance of catalysts is correlated to their properties, particularly their ...

Distinction of electron pathways at titanium oxide/liquid interfaces in photocatalytic processes and co-catalyst effects.

Photocatalytic reactions include several different steps and routes for photoexcited carriers, and each dynamic is closely related to the reaction efficiency. Although commonly used time-resolved techniques can reveal the kinetics of photoexcited carriers, the reaction pathways are difficult to distinguish due to decay kinetics extending over many temporal orders and various contributions from ...
