QUANTUM-THEORY OF DIFFUSION - TEMPERATURE DEPENDENCE OF DIFFUSION OF LIGHT INTERSTITIALS IN DEBYE SOLIDS [PDF]
The temperature dependence of the motion of light interstitials is calculated using the quantum theory of Flynn and Stoneham (1970). The results are compared with the asymptotic expressions given previously. They show that the high temperature asymptotic

Overturn of ilmenite‐bearing cumulates in a rheologically weak lunar mantle [PDF]
©2019. American Geophysical UnionThe crystallization of the lunar magma ocean (LMO) determines the initial structure of the solid Moon. Near the end of the LMO crystallization, ilmenite‐bearing cumulates (IBC) form beneath the plagioclase crust.

Dataset of the liquid water distribution in a biomimetic PEM fuel cell
This dataset gathers the initial formation and the evolution of water content and distribution, as well as water evacuation, within a lung-inspired PEM (proton exchange membrane) fuel cell with a 50 cm2 active area for various operating conditions such ...

The Bond-Energy Bond-Order (BEBO) Model of Chemisorption [PDF]
The bond-energy bond-order (BEBO) model of chemisorption allows an estimate to be made of the interaction energy between a gaseous specie and a solid surface as a function of either bond length or bond order, i.e., the length or order of either the gas ...

ACTIVATION ENERGY FOR FISSION [PDF]
The experimentally determined exponential dependence of spontaneous fission rate on Z{sup 2}/A has been used to derive an expression for the dependence of the fission activation energy on Z{sup 2}/A. This expression has been used to calculate the activation energy for slow neutron induced fission and photofission.

Deep Learning of Activation Energies [PDF]
Quantitative prediction of reaction properties, such as activation energy, have been limited due to a lack of available training data. Such predictions would be useful for computer-assisted reaction mechanism generation and organic synthesis planning. We develop a template-free deep learning model to predict activation energy given reactant and product
