Summary: In this study, silver nanowires were synthesized efficiently using the polyol-microwave method, with optimal conditions obtained at 210 seconds of microwave irradiation time. Characterization results showed that silver nanowires with an average diameter of 80 nm and length of 20 µm could be produced efficiently under these optimal conditions.

Summary: This paper presents a study on the synthesis of silver nanowires using the polyol process by conventional and microwave heating. Various polyols with different viscosities and dielectric properties were used as reductants, resulting in nanowires with an average diameter of 119-198 nm. The heating method had a limited effect on the average diameter and length value of the final product, in contrast to the viscosity and dielectric constant of the alcohol used. The performed studies indicate an optimal strategy for fabricating one-dimensional silver nanostructures using the polyol method.

Summary: This study synthesized AgNWs at different quenching temperatures and found that lower quenching temperatures resulted in shorter lengths and higher mechanical strength of AgNWs. UV-Vis and thermogravimetric analysis revealed that AgNWs quenched at -80 degrees Celsius exhibited better thermal stability compared to those quenched at higher temperatures.

Summary: In this study, a cesium silver bismuth bromide (Cs2AgBiBr6) perovskite was synthesized using a microwave-assisted solvothermal method, which offers a simple and rapid sample synthesis. The obtained bismuth-based perovskites showed high purity under non-inert conditions, as confirmed by X-ray diffraction and Raman spectroscopy. The synthesized material exhibited favorable moisture and thermal stability, and its electronic structure and carrier lifetime were characterized by ultraviolet-visible spectroscopy and temperature-dependent photoluminescence spectroscopy, respectively. These findings demonstrate a feasible method for the production of Cs2Ag-BiBr6 perovskite nanoparticles.

Summary: A new polyol-based method for the synthesis of silver nanorings was reported, with the effects of PVP molecular weight, KBr concentration, reaction time, and stirring speed on the morphologies studied. The silver nanorings obtained had a ring diameter of around 10 µm and wire diameters in the range of 20-40 nm, showing great potential for applications in nanoscale photonics, plasma devices, and optical manipulation.

Summary: Ag nanocubes were synthesized using a sodium sulfide assisted solvothermal method, achieving different refractive index sensitivities under varying conditions. By utilizing the interaction of 4-aminothiophenol immobilized on the nanocubes with formaldehyde, successful detection of formaldehyde in water and milk samples was achieved.

Summary: This study investigates the roles of polyvinyl-pyrrolidone (PVP) and bromide (Br-) in the anisotropic growth of Ag nanocubes using seed-mediated growth, single-crystal electrochemistry, and surface-enhanced Raman spectroscopy (SERS). The results show that Ag nanocubes can only form in the presence of both PVP and sufficiently high concentrations of Br-. Truncated octahedra form in the presence of PVP alone, and truncated cubes form in the presence of Br- alone. The study suggests that the chemisorption of Br- beneath a physisorbed layer of PVP creates a unique condition for the growth of Ag nanocubes.

Summary: This study successfully synthesized g-C3N4 and nanostructures of silver nanocubes with cobalt ferrite, and tested their catalytic activity for hydrogen and oxygen evolution reactions. It was found that Ag@CoFe2O4/g-C3N4 exhibited the highest catalytic activity and the lowest overpotential for HER, making it a promising candidate for practical applications.

Summary: In this study, polyvinylidene fluoride (PVDF) membrane was modified with silver nanoparticles (AgNPs) embedded on cellulose nanocrystals (CNCs) to improve their antibacterial properties. The CNC-capped AgNPs were synthesized via microwave assisted methods and then embedded into PVDF membrane using the phase-inversion technique. The modified PVDF membrane showed strong antibacterial activity, reducing the number of live cells by up to 98%.

Summary: Water pollution poses a serious threat to life on earth, and urgent attention should be given to the presence of hazardous organic dyes in industrial effluents. Nanocatalysts can effectively photodegrade these dyes, and metal-based nanocatalysts are preferred due to their high surface area and suitable energy band gap. In this study, silver nanoparticles (AgNPs) with different morphologies (cubic and rod shapes) were synthesized using the polyol reduction method, and their effects on photocatalytic degradation of dyes and antibacterial properties were evaluated.
