Chemistry – A European Journal, EarlyView.The energetics of the addition reaction of P‐centered radicals onto alkenes are primarily ruled by the stability of the attacking radical, as outlined by the computational screening of a wide range of reactions. In addition, donor‐acceptor substituents at the olefin have an important tuning role.

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.The ionization of anthracene, acridine, and phenazine has been explored, along with the removal of one and two hydrogen atoms, to provide valuable information for astrochemists and to understand the behavior of the resulting structures and their electronic reorganization. Abstract In this study, we systematically explored the stability and isomerism of

CN and HCN in Dense Interstellar Clouds
, 2005 We present a theoretical investigation of CN and HCN molecule formation in dense interstellar clouds. We study the gas-phase CN and HCN production efficiencies from the outer photon-dominated regions (PDRs) into the opaque cosmic-ray dominated cores.

Confined Hot Carrier Cooling Via Excited‐State Energy Gap Engineering in Graphyne Carbon Allotropes
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.The excited‐state energy gap (EEG), regulated by the concentration of sp‐hybridized carbon, provides an effective handle for tuning electron–phonon coupling behavior. This design enables long‐lived confinement of hot carriers near the top of the EEG with controllable energy levels.
