A Critical Evaluation of the Role of the Precursor Complex and Counterions in Synthesis of Gold Nanoparticles in Micellar Media [PDF]

open access: yesarXiv, 2016
We demonstrate here that the gold nanoparticles (AuNPs) obtained in micellar solutions are susceptible to the precursor complex nature and specific counterion effects controlling the reaction kinetics, particles size and shape. The tested approach consisted in reducing the HAuCl4 complex with ascorbic acid or citric acid in dodecyltrimethylammonium ...

Behavior of aqueous Tetrabutylammonium bromide - a combined approach of microscopic simulation and neutron scattering [PDF]

open access: yesarXiv, 2016
Aqueous solution of tetrabutylammonium bromide is studied by quasi-elastic neutron scattering, to give information on the dynamic modes involving the ions present. Using a careful combination of two techniques, time-of-flight (TOF) and neutron spin echo (NSE), we de- couple the dynamic information in both the coherently and incoherently scattered ...

High-End State-of-Art Copper Bromide Vapor Lasers: Optical, Electric and Thermal Properties [PDF]

open access: yesarXiv, 2017
Copper bromide vapor laser is the most successful sealed-off version of a plenty of copper vapor lasers launched, studied and produced for the last half of century. Being first reported in 1975, it became the leading and long-lasting R&D&T project followed by the Laboratory of metal vapor lasers in Institute of solid state physics of the Bulgarian ...

Liquid-like Free Carrier Solvation and Band Edge Luminescence in Lead-Halide Perovskites [PDF]

open access: yesarXiv, 2018
We report a strongly temperature dependent luminescence Stokes shift in the electronic spectra of both hybrid and inorganic lead-bromide perovskite single crystals. This behavior stands in stark contrast to that exhibited by more conventional crystalline semiconductors.
