Production of ultrafine ag nanoparticles by laser ablation in diluted sodium borohydride
solution and their antibacterial properties.
(6-8) In past years, several agents, such as ammonia-ethanol, borohydride
, and Sudan Black B, were used to reduce the AF of FFPE tissues.
Unused reductant 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).
The silver nanotriangles were synthesized by reducing silver nitrate (0.14 mM, 50 mL) with sodium borohydride
(0.21 M, 250 [micro]L) in the presence of sodium citrate (30.2 mM, 3mL) and 120 [micro]L of [H.sub.2][O.sub.2] (Golden Bell, 30%), in this order of addition, under magnetic stirring at room temperature to 1500 rpm; physical changes were transparent coloration change to a yellow tone and immediate change to blue tone indicative of the formation of silver nanotriangles (Ag NTs); after that, the reaction was completed, obtaining a final concentration after dilution of 2.65 x [10.sup.-5] M.
Analytical grade low molecular weight chitosan (75-85% deacetylated), titanium tetra isopropoxide (TTIP, 97% assay), sodium borohydride
, glutaraldehyde (25% in [H.sub.2]O), acetic acid, and NaOH were purchased Sigma-Aldrich.
CO2 can be converted to alternate fuel by first reacting it with freshly prepared methyl magnesium bromide, CH3MgBr (Grignard's reagent) and then reducing the resultant product into Ethanol (C2H5OH) by using Sodium Borohydride
(NaBH4) along with other electrophiles.
Iron (II) chloride tetrahydrate (Fe[Cl.sub.2]*4[H.sub.2]O), sodium borohydride
(NaB[H.sub.4]) and ethanol were supplied by Sigma Aldrich.
In short, disulphide bonds were first reduced to form-free functional thiol groups with sodium borohydride
. Unused reductant sodium borohydride
was consumed and removed with formaldehyde to prevent reduction of 5,5'-dithiobis-(2-nitrobenzoic acid), and all of the thiol groups, including reduced and native thiol groups, were determined after the reaction with 5,5'-dithiobis-(2-nitrobenzoic acid).
We have for the first time synthesized Ag NPs by [gamma]-radiation method and investigated them as electrocatalysts for the oxygen reduction and borohydride
oxidation reactions .
(iv) Colloidal dispersion of copper nanoparticles: the particles were prepared in the aqueous phase by a chemical reduction of copper chelate complex solution using sodium borohydride
AgNPs were synthesized by reduction of silver nitrate (AgN[O.sub.3]) with sodium borohydride
(NaB[H.sub.4]) using a modified version of the procedure described in Ref.
