Pyrite is an excellent reductant
, and consequently in many places the pyrite has been completely replaced by chalcopyrite, bornite and chalcocite (see figures 5 and 6).
More than 40% of that cost is directly attributable to the 6+ metric tonnes of raw material (silicon dioxide and reductant
) needed to produce 1 MTof metallurgical grade silicon metal.
But by using fenugreek seed extract as reductant
Cu NPs were not oxidized to CuO NPs.
But surely AW, anyone made reductant
after Brexit will be able to 'adapt' using their acquired Brexit freedoms to create new jobs by accessing the wider and growing markets outside of the EU?
 Redox photosensitizer: A component that initiates the photochemical one-electron transfer from a reductant
to a catalyst.
sodium borohydride was consumed and removed with formaldehyde, and all thiol groups, including reduced and native ones, were detected after reaction with 5, 5'-dithiobis-(2-nitrobenzoic) acid (DTNB).
Urea-SCR, which uses ammonia as the reductant
, is considered a promising and arguably necessary technology to selectively reduce NOx present in the diesel exhaust .
To establish the best condition for biofabrication of nano-Ag to get the large mass weight of nano-silver, the biofabrication reactions set up were prepared by using the different concentration of the precursor (0.5, 1.0, 2.0M) which prepared and added to the different reductant
concentration (0.5, 5.0, 10.0 % v/v), then these mixtures were incubated at different temperature (30, 40 and 50[degrees]C) in ranges of pH (5.5-6) in light or dark conditions (Table 3), Box-Behnken modeling and the final results analysis were carried out using the Microsoft Excel 2007 and essential experimental design software by multiple regression analysis to evaluate the analysis of variance (ANOVA).
This technique promotes the formation of volatile species of As[H.sub.3], Sb[H.sub.3] and Se[H.sub.2], using borohydride as a reductant
(Ranesh and Riyazuddin, 2005).
This carbon char has application as a carbon reductant
in the steel and alloy industry, a carbon injection application and further converted into coke briquettes.
The oxidative composition has a pH less than 7.5 and a reductant
composition has a pH greater than 7.
(Milan, Italy) and the composition of the studied blend is 25 wt% of SnS and 65 wt% of Sn[S.sub.2], and the remaining is a 10wt% of natural graphite (introduced in the synthesis blend to create a reductant
and lubricant medium and the same used to make the studied blends) with particle size D10, D50, and D90 of 4, 20, and 52 [micro]m, respectively.
