Proton conductivity in borax, Na2[B4O5(OH)4]-8H2O

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...

Defect Chemistry and Proton Conductivity in Ba-based Perovskites

The site incorporation mechanism of M dopants into ABO3 perovskites controls the overall defect chemistry and thus their transport properties. For charge balance reasons, incorporation onto the A site would require the creation of negatively charged point defects, such as cation vacancies, whereas incorporation onto the B site is accompanied by the generation of positively charged defects, typi...

Enhanced Proton Conductivity in Y‐Doped BaZrO3 via Strain Engineering

The effects of stress-induced lattice distortions (strain) on the conductivity of Y-doped BaZrO3, a high-temperature proton conductor with key technological applications for sustainable electrochemical energy conversion, are studied. Highly ordered epitaxial thin films are grown in different strain states while monitoring the stress generation and evolution in situ. Enhanced proton conductivity...

Respiratory effects of borax dust.

The relation of respiratory symptoms, pulmonary function, and abnormalities of chest radiographs to estimated exposures of borax dust has been investigated in a cross sectional study of 629 actively employed borax workers. Ninety three per cent of the eligible workers participated in the study and exposures ranged from 1.1 mg/m3 to 14.6 mg/m3. Symptoms of acute respiratory irritation such as dr...
