Published in 2018 at "Russian Physics Journal"

DOI: 10.1007/s11182-018-1312-y

Abstract: A spatiotemporal kinetics of the active medium of a copper vapor brightness amplifier is described that allows gain characteristics to be investigated during the pump pulse. Model calculations show that changing the discharge parameters allows… read more here.

DOI: 10.1016/j.jorganchem.2021.121910

Abstract: Abstract Based on triethoxy(3-(1,1,1,2,5,5,5-hepatfluoro3 - (perfluoropropan-2-yl) - 4-(trifluoromethyl)pent-3-en-2-yl) oxy)propylsilane, obtained from the commercially available trimer hexafluoropropylene, branched oligosiloxanes were synthesized by hydrolytic polycondensation in the active medium . The resulting polymers were studied by NMR… read more here.
