An integrated field-effect microdevice for monitoring membrane transport in Xenopus laevis oocytes via lateral proton diffusion. [PDF]

PLoS ONE, 2012
An integrated microdevice for measuring proton-dependent membrane activity at the surface of Xenopus laevis oocytes is presented. By establishing a stable contact between the oocyte vitelline membrane and an ion-sensitive field-effect (ISFET) sensor ...

Proton coupled electron transport of pH sensitive coumarin based ruthenium(II) complex: A functional mimic of photosystem II

Journal of Photochemistry and Photobiology, 2021
In this work, we have explored a new pH sensitive coumarin based ruthenium(II) complex (R1QC) to mimic the role of P680 in donor side of photosystem II in natural photosynthesis.

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.

Measured and simulated transport of 1.9 MeV laser-accelerated proton bunches through an integrated test beam line at 1 Hz

Physical Review Special Topics. Accelerators and Beams, 2010
A laser-driven repetition-rated 1.9 MeV proton beam line composed of permanent quadrupole magnets (PMQs), a radio frequency (rf) phase rotation cavity, and a tunable monochromator is developed to evaluate and to test the simulation of laser-accelerated ...

Sodium and proton transport in Mycoplasma gallisepticum [PDF]

Journal of Bacteriology, 1985
When washed cells of Mycoplasma gallisepticum were incubated at 37 degrees C in 250 mM 22NaCl, the intracellular Na+ increased, and the K+ decreased. The addition of glucose to these Na+-loaded cells caused Na+ efflux and K+ uptake (both ions moving against concentration gradients).
