Using Electrolysis for More Than Just Generating Hydrogen

Last night I bombarded the fattest tube I have ever pumped. At 100mm diameter, 3mm wall thickness and about 5 feet long, its big.
This one is #borosilicate so I had a boro worker shrink it down and make the seals on a glass lathe.Bombarding this is tricky, as the 19mm electrode glass is only 1.5 mm thick and will heat up more rapidly than the diffuse arc in the larger, thicker tube. To aid in the process, I wrapped the thick tube in the carcinogenic (but oh so insulative) frax blanket- which helped keep the heat in the middle like a jacket while the exposed #electrode extremities could cool down in between blasts from the bombarder.
I started with sorta normal pressures and currents (about 450ma current at about 5 torr of air) and then eventually ramped up to bombarding with about 1100ma of current at up to 17 torr of pressure! The outside took awhile to cool off and #vacuum out.
Gosh I wanna make one with xenon!

#1N5817 Schottky Barrier Rectifying #Diode is one of many #semiconductors powering modern #technology.
#Faroese word for it is #hálvleiðari (#hálv - half-way + #leiðari - conductor), while #electrode is called #kleiv - a word that originally meant a "narrow cleft".

A paper with a long and tortuous journey has finally found its home. It has been a pleasure to work with all my colleagues at both Freie Universität Berlin and St. Petersburg State University and to put the article together, method by method. All to underline the importance of finding a match in the interactions of the backbone and the #redox species in a polymeric #electrode material, and shown how an assortment of approaches builds up to a nice description of an object.

Decoding of #electrical #brain activity continues to make great progress. The currents, measured by direct #electrode attachment to the brain, are now being translated into text, audio, and facial avatar #animations by #deeplearning models. A new #work succeeded in enabling precise expressiveness at sufficient speed and providing an approach to full embodied #communication.

A promising #material for #hydrogen #energy devices. The new material has high #proton #conductivity and unusual properties (depending on the degree of doping). It can be used as an #electrolyte (at high doping levels) and as an #electrode (at low doping levels) in solid oxide #fuel #cells and electrolyzers.
