Oriented MOF-polymer Composite Nanofiber Membranes for High Proton Conductivity at High Temperature and Anhydrous Condition

The novel oriented electrospun nanofiber membrane composed of MOFs and SPPESK has been synthesized for proton exchange membrane fuel cell operating at high temperature and anhydrous conditions. It is clear that the oriented nanofiber membrane displays the higher proton conductivity than that of the disordered nanofiber membrane or the membrane prepared by conventional solvent-casting method (wi...

Proton conductivity in ampullae of Lorenzini jelly

In 1678, Stefano Lorenzini first described a network of organs of unknown function in the torpedo ray-the ampullae of Lorenzini (AoL). An individual ampulla consists of a pore on the skin that is open to the environment, a canal containing a jelly and leading to an alveolus with a series of electrosensing cells. The role of the AoL remained a mystery for almost 300 years until research demonstr...

Catalytic Olefin Hydroamidation Enabled by Proton-Coupled Electron Transfer

Here we report a ternary catalyst system for the intramolecular hydroamidation of unactivated olefins using simple N-aryl amide derivatives. Amide activation in these reactions occurs via concerted proton-coupled electron transfer (PCET) mediated by an excited state iridium complex and weak phosphate base to furnish a reactive amidyl radical that readily adds to pendant alkenes. A series of H-a...

Stress in LiNbO3 proton-exchanged waveguide layers

Penetration of hydrogen ions in the crystal lattice of LiNbO3 certainly causes stress in the proton-exchanged region, especially when the level of doping is high. In the present study, a correlation between stress and the level of doping (respectively, between stress and the phase composition of the measured layer) has been obtained. Proton-exchanged waveguide layers in X, Y and Z-cut LiNbO3 ha...
