NUMERICAL ANALYSIS OF GAS-DROPLET CHEMICAL PLUG-FLOW REACTOR OPERATING MODES
Вестник Донского государственного технического университета, 2018 A one-dimensional model and numerical solution of the non-stationary modes of the adiabatic gas-droplet chemical plug-flow reactor are considered. The developed approach permits to investigate processes of heat and mass transfer in the laminar flow of ...

Enhancing Triplet Excitons Lifetime Through Controlled Intermolecular Interactions
Advanced Optical Materials, EarlyView.Singlet fission (SF) is investigated in pentacene embedded in a surface‐anchored metal–organic framework, enabling a molecular arrangement inaccessible in pure organic crystals. This architecture changes the singlet fission dynamics significantly and enhances the triplet lifetime by almost four orders of magnitude.
