The synthesis that is described in this study is for the preparation of silver nanoparticles of sizes ranging from 10 nm to 30 nm with a defined shape (globular), confirmed by UV-vis, SEM, STEM and DLS analysis. This simple and favorable one-step modified Tollens reaction does not require any special equipment or other stabilizing or reducing agent except for a solution of purified mesquite gum...

We synthesize Au@Ag core/shell nanoparticles (NPs) using a Au NP assisted Tollens reaction. The as-synthesized NPs are used for the colorimetric cyanide sensing with a detection limit of 0.4 μM. The bimetallic NPs are immobilized into agarose gels as portable "test strips".

This paper is devoted to the study of discrete implications that satisfy modus ponens (MP), modus tollens (MT) or both (MPT). The main goal is to characterize all R, S, QL and D-implications on a finite chain L satisfying these properties for a given smooth t-norm T1. The non-smooth case is also discussed for a special family of t-norms.

Based on our previous researchs about generalized modus ponens (GMP) with linguistic modifiers for If ... Then rules, this paper proposes new generalized modus tollens (GMT) inference rules with linguistic modifiers in linguistic many–valued logic framework with using hedge moving rules for inverse approximate reasoning.

This paper is devoted to the research of full implication triple I method under Pythagorean fuzzy environment. We first propose concepts t-norm, t-conorm, residual operator (RPFIO) and biresiduum. The for modus ponens (PFMP) tollens (PFMT) are also established. In addition, properties PFMP PFMT models including robustness, continuity reversibility analyzed. Finally, a practical problem discusse...

Nanosilver (nAg) was prepared via Tollens method using dextrin as stabilizer. The morphology, size distribution and average size of the obtained nAg were characterized using Transmission electron microscope (TEM) and Dynamic light scattering (DLS) technique. A kinetic study of toxicity of nAg on Escherichia coli (E. coli) was determined. The obtained results showed that nAg exhibits spheric sha...

This review presents an overview of silver nanoparticles (Ag NPs) preparation by green synthesis approaches that have advantages over conventional methods involving chemical agents associated with environmental toxicity. Green synthetic methods include mixed-valence polyoxometallates, polysaccharide, Tollens, irradiation, and biological. The mixed-valence polyoxometallates method was carried ou...

Holographic reduced representation is based on a suitable distributive coding of structured information in conceptual vectors, which elements satisfy normal distribution N(0,1/n). Existing applications of this approach concern various models of associative memory that exploit a simple algebraic operation of scalar product of distributed representations to measure an overlap between two structur...

A transparent conducting film composed of regular networks of silver nanowires is obtained by combining a soft solution process (Tollens' reaction) and nanoimprint lithography. The solution-grown nanowire networks show a threefold higher conductivity than grids obtained by metal evaporation. This is due to the larger grain size in the solution-grown nanowires, which results in a strong reductio...
