Silver nitrate is a moderately strong oxidant that can be reduced by a number of moderately strong or strong reducing agent to become elemental silver. Hydrazine (N2H4) and phosphorous acid and reduce Ag+ to metallic silver with the reaction equation: (1) N2H4 + 4AgNO3─ → 4Ag + N2 + ...
Chitosan (Cs) with a molecular weight of 100.000–300.000 and degree of deacetylation more than 85% (Acros, Belgium), Acrylamide (AAm) with a purity of 99.9% (Merck, Germany), Silver nitrate (AgNO3) and Sodium borohydride (NaBH4) (Qualikems Fine Chem., India), Gold (III) chloride (AuC...
The reduction of Ag+ ions to Ag° nanoparticles was indicated by changing the color of any given solution mixture to yellowish–brown gradually increasing to deep brown color depending on both concentration of silver nitrate and the reducing agent. Authors use a wide range of AgNO3concentration in...
Using 1 mM silver nitrate, the cell-free fungal supernatant was utilized to synthesize silver nanoparticles. The filtrate was added to silver nitrate solution by a ratio of 1:1 and left at room temperature (25 ºC) for 24 h, in the dark. Following incubation, the produced silver ...
The average crystallite size of synthesized AgNPs was evaluated by using Scherrer’s formula (as shown in Equation (1)). (1) where D: the crystallite size K: the dimensionless shape factor (0.9) λ: the X-ray wavelength (1.5418 Å for CuKα) β: the line broadening at half ...

The fluorescence-quenching constants kq for SA, obtained using the Stern–Volmer equation (Equation (4)) and the corresponding plots (Figures S8 and S9), were found to fall in the range of 1011-1012 M−1s−1 (Table 5), suggesting a static emission-quenching mechanism due to the potenti...
Aqueous silver nitrate solution (AgNO3, 1 mM) was stored in a cold, dark place. Then, ELLE (10 mL) was added to AgNO3 solution (90 mL), and the mixture was incubated overnight in a dark environment to reduce Ag+ ions. The formation of a yellowish-brown tint suggested the production ...
Finally, the volumes and size distributions of the pores were calculated using the Washburn equation [59], which is as follows: 𝑃𝐶=2𝜎cos𝜃𝑟PC=2σcosθr (3) where PC—capillary pressure σ—mercury interfacial tension θ—contact angle r—pore radius. The samples were also ...
TTIP (27 mmol) into ethanol (60 mL) under vigorous stirring (300 rpm). Then, citric acid (54 mmol) was added in a molar ratio of 2:1 with respect to Ti4+ions. On the other hand, solution B was prepared by dissolving a stoichiometric amount of silver nitrate (4 mmol) and strontium...
