If surface energy is decreased to below 60 mN m-1 by adding more propanol to the water/propanol mixture used as substrate, molecules with long side chains (n = 140) that readily break on a 99.8/0.2 wt/wt% water/propanol surface (γ = 69 mN m-1) remain intact.
The catalytic activity expressed as the intrinsic rate of CH4 conversion increased by adding Mn to the CuZnMgAl mixed oxide calcined at 650 °C and by increasing its content.
Plates were then incubated with streptavidin (RD Systems, Minneapolis, MN, USA) and revealed by adding H2O2 and orthophenylenediamine (Sigma Aldrich, St . Louis MO, USA).
Remediation strategies for sites contaminated with redox sensitive metals can benefit from the results of this study by realizing that the oxidation capacity of Mn-oxides can be bolstered by adding sulfur or lime amendments to adjust soil pH.
The Cu/ZnO/Al2O3 catalysts, prepared by co-precipitation method, have been modified by adding small amount of Mn, Mg, Zr, Cr, Ba, W and Ce oxides using design of experiments (1/16 full factorial design).
Briefly, the stock solution was prepared by adding Zn(CH3COO 2·2H2O and Mn(CH3COO 2·2H2O into 100 mL 0.12 M TGA aqueous solution respectively.
After 30 mn incubation at 37°C, reactions were stopped by adding 2 μl of 6× loading buffer (0.025% Bromophenol blue; 0.025% xylene cyanol; 60% glycerol; 1% SDS; 100 mM EDTA) and inactivation for 10 mn at 70°C.
The modification of Cu/ZSM-5 by adding different transition metals (Co, Mn, Cr and Fe) to improve the efficiency of NO conversion was studied.
This alloy was fabricated by adding 1.0% excess Cu, 0.24% Mn, and 0.16% Zr to the standard composition.
A slight enhancement effect was observed by adding K or Ca. By adding Mn on Ni/dolomite, the better toluene conversion efficiency to CO and CO2 was obtained than K and Ca and maintained constantly because of the resistance of carbon deposition.
