“…Silver dendrites have been synthesised by various techniques, including template method (where poly (vinyl alcohol), poly (vinyl pyrrolidone), Raney Nickel and monocrystalline silicon serve as templates), template less direct growth (aging a silver salt with reducing agent), electrochemical method (electrochemical reduction of Ag+ ions), electroless metal deposition/galvanic displacement (micro electrochemical redox reaction on Si wafer, Cu and Al foil substrates), sonoelectrochemical method (applying ultrasound to the electrochemical method), microwave, photoreduction, and wet‐chemical route (reduction of silver ions in solution with soluble reducing agents) . However, the disadvantages including unwanted by‐product formation and difficulty to avoid contamination in the template method, immature dendrites due to low reaction progress in the template less direct growth method, morphological transition due to relaxation process in electrochemical method are notable .…”

Benzene centered tris-alkylimidazolium bromide salts, denoted as BTIm(R) 3 Br 3 ; where R = C 12 H 25 and C 14 H 29 have been prepared and structurally characterised. The hydrogelation ability and stabilizer role of these salts for the synthesis of silver nanoparticles (AgNPs) via chemical reduction method is described. A worth note that the BTIm(C 12 ) 3 Br 3 compound could lead a thermoreversible fibrous-hydrogel in water, which plays a dual role as stabilizer and directing agent for silver dendritic nanostructures. While the partial-hydrogel of BTIm(C 12 ) 3 Br 3 contributes silver nanospheres. The non-gel solutions of BTIm (C 12 ) 3 Br 3 in dichloromethane, and BTIm(C 14 ) 3 Br 3 in water as stabilizers did not show control over the shape of AgNPs, and they lead mixed morphology. The experimental conditions, i. e. temperature, heating-cooling process and the physical state of the stabilizer play a key role in the thermoreversible hydrogel and partial-hydrogel control over the morphology of Ag nanostructures. Overall, the outcome of the present study provides new possibility for the use of thermoreversible fibrous gels to prepare Ag dendrites.[a] Dr.

“…Other peel extracts including Carica papaya were also employed in the Ag nanoparticle synthesis (Balavijayalakshmi & Ramalakshmi, 2017). The development of green synthesis for conductive inks will be advantageous for both industrial and environmental points of view (Supraja et al, 2018;Wang et al, 2017).…”

Silver (Ag) nanospheres were chemically reduced from 1 mM silver nitrate (AgNO3) solutions using mulberry (Morus alba Linn.) leaf extracts. The increase of pH in the synthesis from 9 to 13 modified the surface plasmon resonance peak in UV-Vis spectra relating to the particle diameter around 20 nm. Smaller nanoparticles were obtained from the syntheses at pH 7.4-7.7 and their density was slightly increased with the increase in synthesis temperature from 25 °C to 90 °C. The particle size was increased with increasing AgNO3 concentration from 0.1 to 0.5 M but the mixed phases were obtained from the 0.5 M AgNO3 precursor. After storing for 10 months at room temperature, the nanosuspensions remained without Ag sediment but their colors had significantly changed due to particle agglomerations. The colors were characterized by the smartphone colorimetry according to the RGB, CIE space, as well as chroma and hue angle. Based on the chroma and CIE b* values, the effect of synthesis pH in the stored nanosuspensions was comparable to that before the storage. Although the temperature had only moderate effects, nanosuspensions synthesized at 25 °C, 80 °C, and 90 °C were clearly distinguished by the hue and CIE b* values.
