Pressure-induced amorphization of a dense coordination polymer and its impact on proton conductivity

APL Materials, 2014
The proton conductivity of a dense coordination polymer (CP) was investigated under high-pressure conditions. Impedance measurements under high pressures revealed that the proton conductivity of the CP decreased more than 1000-fold at pressures of 3–7 ...

Structural mechanism of proton conduction in otopetrin proton channel

Nature Communications
AbstractThe otopetrin (OTOP) proteins were recently characterized as extracellular proton-activated proton channels. Several recent OTOP channel structures demonstrated that the channels form a dimer with each subunit adopting a double-barrel architecture.

Patient-specific stopping power calibration for proton therapy planning based on single-detector proton radiography. [PDF]

, 2015
A simple robust optimizer has been developed that can produce patient-specific calibration curves to convert x-ray computed tomography (CT) numbers to relative stopping powers (HU-RSPs) for proton therapy treatment planning.

Sulfophenylated centimeter-sized graphene membrane in a direct methanol fuel cell

Nature Communications
An ideal proton exchange membrane should only allow protons to pass and remain impermeable to fuels, as required in fuel cell applications. In methanol fuel cells, high proton conductivity enables high power density, whereas methanol crossover between ...

Dendritic phytic acid as a proton-conducting crosslinker for improved thermal stability and proton conductivity

Communications Materials
There is growing interest in materials that exhibit enhanced proton conductivity at elevated temperatures without the need for humidification. Here, we develop a dendritic proton-conducting dopant for proton exchange membranes based on phytic acid (PhA ...
