Collisions of Nucleons with Atoms: Calculated Cross Sections and Monte Carlo Simulation

Frontiers in Physics, 2021
After a summary description of the theory of elastic collisions of nucleons with atoms, we present the calculation of a generic database of differential and integrated cross sections for the simulation of multiple elastic collisions of protons and ...

Cryo-EM structure of the lysosomal chloride-proton exchanger CLC-7 in complex with OSTM1

eLife, 2020
The chloride-proton exchanger CLC-7 plays critical roles in lysosomal homeostasis and bone regeneration and its mutation can lead to osteopetrosis, lysosomal storage disease and neurological disorders.

Lactate-proton co-transport and its contribution to interstitial acidification during hypoxia in isolated rat spinal roots [PDF]

, 1993
Exposure of nervous tissue to hypoxia results in interstitial acidification. There is evidence for concomitant decrease in extracellular pH to the increase in tissue lactate.

How dynamics in hydrogen-bonding networks define proton channel selectivity and conductivity [PDF]

Structural Dynamics
The precise transport of protons across cellular membranes is key for many biocatalytic and bioenergetic processes. Proton channels facilitate the selective and efficient movement of protons for all necessary functions while maintaining membrane fidelity

Electron and proton heating by solar wind turbulence [PDF]

, 2009
Previous formulations of heating and transport associated with strong magnetohydrodynamic (MHD) turbulence are generalized to incorporate separate internal energy equations for electrons and protons. Electron heat conduction is included.

Transport of Solar Wind Fluctuations: A Two-Component Model [PDF]

, 2011
We present a new model for the transport of solar wind fluctuations which treats them as two interacting incompressible components: quasi-two-dimensional turbulence and a wave-like piece.

Surface proton transport of fully protonated poly(aspartic acid) thin films on quartz substrates [PDF]

, 2014
Thin film structure and the proton transport property of fully protonated poly(aspartic acid) (P-Asp100) have been investigated. An earlier study assessed partially protonated poly(aspartic acid), highly oriented thin film structure and enhancement of ...

Charge transport along proton wires [PDF]

Biointerphases, 2013
Abstract Using density functional theory we look at the quantum mechanics of charge transport along water wires both with free ends and donor/acceptor terminated. With the intermediate geometries in the DFT iterations we can follow the charge transfer mechanism and also construct the energy landscape explicitly.
