A large number of experimental studies have been devoted to quantifying the interaction between transmembrane (TM) helices in detergent micelles and, more recently, in bilayers. Theoretical calculation of association free energy of TM helices would be useful for predicting the propensity of given sequences to oligomerize and for understanding the difference between association in micelles and i...

Vibrational and rotational energy relaxation in liquids are studied by means of computer simulations. As a precursor for studying vibrational energy relaxation of a solute molecule subsequent to the formation of a chemical bond, the validity of the classical Bersohn-Zewail model for describing the intramolecular dynamics during photodissociation is investigated. The apparent agreement with quan...

A novel concept for the deflection of rotating asteroids is presented, based on conversion asteroid rotational kinetic energy into translational energy. Such achieved using an orbital siphon, a tether-connected chain masses, arranged vertically from surface, which exploits rotation delivery mass to escape. Under conditions be discussed, siphon can initiated ensure self-sustained flow This mecha...

Energy harvesting from vibration for low-power electronics has been investigated intensively in recent years, but rotational energy harvesting is less investigated and still has some challenges. In this paper, a methodology for low-speed rotational energy harvesting using piezoelectric transduction and frequency up-conversion is analysed. The system consists of a piezoelectric cantilever beamwi...

Recent modeling of thermal nonequilibrium processes in simple molecules like hydrogen and nitrogen has indicated that rotational nonequilibrium becomes as important as vibrational nonequilibrium at high temperature. In this study, to analyze rotational nonequilibrium, the rotational mode is separated from the translational-rotational mode that is usually considered in two-temperature models. Th...

The dynamics of the hydrogen abstraction reaction between methane and hydroxyl radical is investigated using an initial state selected time-dependent wave packet method within a six-dimensional model. The ab initio calibrated global potential energy surface of Espinosa-García and Corchado was used. Integral cross sections from several low-lying rotational states of both reactants have been obta...
