Maximizing Free Energy Gain [PDF]

open access: yesEntropy
Maximizing the amount of work harvested from an environment is important for a wide variety of biological and technological processes, from energy-harvesting processes such as photosynthesis to energy storage systems such as fuels and batteries. Here, we

DISORDER SOLUTIONS FOR GENERALIZED ISING AND POTTS MODELS WITH MULTISPIN INTERACTION

open access: yesСовременные информационные технологии и IT-образование, 2019
In this work, a special elementary transfer matrix is constructed for generalized Ising models and Potts models with the general form of a finite Hamiltonian with a multi-spin interaction in a space of arbitrary dimensionality, the Napierian logarithm of

How to analyse the performances of innovative variable diffusivity membranes integrated within prefabricated timber facades Compute

open access: yesJournal of Facade Design and Engineering, 2018
Vapour barriers and retarders are often needed to improve the hygro-thermal performance of the building envelope. Their use is particularly important in prefabricated timber façades, especially when critical boundary conditions occur.

Molecular thermal motion harvester for electricity conversion via triboelectrification [PDF]

open access: yesAPL Materials
Molecular thermal motion is ubiquitous, and in theory, the energy of which could be converted into electrical energy. However, not until recently, the conversion of molecular thermal motion into electricity was demonstrated feasible for the first time ...

Free Magnetic Energy in Solar Active Regions above the Minimum-Energy Relaxed State [PDF]

open access: yes, 2007
To understand the physics of solar flares, including the local reorganization of the magnetic field and the acceleration of energetic particles, we have first to estimate the free magnetic energy available for such phenomena, which can be converted into ...

Simulation of time-resolved x-ray absorption spectroscopy of ultrafast dynamics in particle-hole-excited 4‐(2-thienyl)-2,1,3-benzothiadiazole

open access: yesStructural Dynamics, 2020
To date, alternating co-polymers based on electron-rich and electron-poor units are the most attractive materials to control functionality of organic semiconductor layers in which ultrafast excited-state processes play a key role.
