Efficiency of plasmochemical production of hydrogen from propane under the influence of laser radiation

Autor: Tveryanovich, Yu. S., Povolotskiy, A. V., Lunkov, S. S.

The plasma-chemical process of producing hydrogen from propane under the excitation by laser radiation has been studied. The study was carried out using femtosecond (35 fs) and nanosecond (7 ns) pulsed laser radiation sources. Experimental dependence

Publikováno v: Phys. Rev. Lett. 132, 056902 (2024)

We synthesize a thin film composed of long carbyne chains terminated by gold clusters and study its optical properties. The presence of gold particles stabilizes longer chains and leads to their alignment. We show that the gold clusters also act as a

Report

Light-induced injection of hot carriers from gold nanoparticles to carbon wire bundles

Autor: Kutrovskaya, Stella, Chestnov, Igor, Osipov, Anton, Samyshkin, Vlad, Lelekova, Anastasya, Povolotskiy, Alexey, Zhou, Xiaoqing, Kavokin, Alexey, Kucherik, Alexey

We observed a light-induced enhancement of the tunneling current propagating through an array of parallel carbon chains anchored between gold nanoparticles (NPs). In the presence of laser radiation characterized by a wavelength close to the plasmon r
