Synthesis, Study, and Discrete Dipole Approximation Simulation of Ag-Au Bimetallic Nanostructures
Water-soluble Ag-Au bimetallic nanostructures were prepared via co-reduction and seed-mediated growth routes employing poly-(4-styrenesulfonic acid-co-maleic acid) (PSSMA) as both a reductant and a stabilizer. Ag-Au alloy nanoparticles were obtained by the co-reduction of AgNO3 and HAuCl4, while Ag-Au core-shell nanostructures were prepared through seed-mediated growth using PSSMA-Au nanopartic...

متن کاملAg dendrite-based Au/Ag bimetallic nanostructures with strongly enhanced catalytic activity.
Dendritic Ag/Au bimetallic nanostructures have been synthesized via a galvanic replacement reaction (GRR) of Ag dendrites in a chlorauric acid (HAuCl4) solution. After short periods of time, one obtains structures with protruding flakes; these will mature into very porous structures with little Ag left over. The morphological, compositional, and crystal structural changes involved with reaction...
متن کاملTHREONINE AMINO ACID MEDIATED PHOTOCHEMICAL SYNTHESIS OF Au, Ag AND BIMETALLIC Au-Ag NANOPARTICLES WITH ANTIBACTERIAL ACTIVITY
Controlled synthesis of metal and bimetallic alloy nanoparticles has gained significant attention due to their unique physico-chemical properties and their potential important applications in the area of medicinal microbiology, drug and DNA delivery, optics and electronics etc. Most of these synthesis routes typically employ toxic chemicals and organic solvents for their synthesis, which limit ...
متن کاملInvestigation of extinction spectra of THTS Mn thin films and comparsion with discrete dipole approximation simulation results
In this work, the extinction spectra of the nano-structure of the Tilt Helical and Stair-like Towers of Mn thin films were obtained using discrete dipole approximation (DDA) simulation for both s-and p-polarization at two incident light angles of 10°, and 60° at different azimuthal angles for the there samples with different tilt. Obtained results are compared with the experimental optical exti...
