Solvent reorganization energy of charge transfer in DNA hairpins

Article Abstract:

The first calculation of the solvent reorganization energy of charge transfer in deoxyribonucleic (DNA) fragments based on the nonlocal, molecular-based description of the solvent response is reported. The study highlights possible limitations of the Marcus-Levich-Jortner (MLJ) formalism in application to charge transfer (CT) in asymmetric charge-transfer system and stresses the necessity of molecular-based modeling of solvent reorganization in CT.

Control of electron transfer rates in liquid crystalline media

Article Abstract:

The solvent reorganization energy of electron-transfer reactions is calculated for a solvent undergoing a structural phase transition from the isotropic to nematic phase. The calculation is based on the response function of the solvent polarization fluctuations obtained from Monte Carlo simulations of a model fluid of hard dipolar spherocylindersin a range of densities covering both the isotropic and nematic phases.

Liquid crystalline nanosheet colloids with controlled particle size obtained by exfoliating single crystal of layered niobate K4Nb6O17

Article Abstract:

Colloids nanosheet of exfoliated layered niobate K4Nb6O17 with controlled lateral size and fixed thickness of 1.8 nm is constructed and their liquidity crystallinty, which is dependent on the lateral size and concentration of nanosheets, is studied. The conclusion states that colloids with larger lateral sizes stably kept liquid crystalline state even at low concentration, which was much lower than that experienced.
