Got to fix another piece of neon to an "NYC Institution" today- Trash and Vaudville.
Although I have never actually been- I did find a photo of where the neon goes online- looks like near the back of the store.
This one was "natural" tube death from sputtered electrodes. They used super tiny electrodes, which run hot and flake off their metal from the electrons running into them. This also reduces the pressure in the tube leading to even more sputtering. Those old blackened shiny electrodes have been on and sputtered for awhile. Probably about a decade or two or even more.
I fixed it by replacing its electrodes, repumping it, and repainting. Took me one hour.
I replaced the electrodes for ones with the shells twice as big. Should be good for decades more. Fixing red neon tubes brings a strange satisfaction, especially when they are ruby red.

What you can see here is the glowing of the argon #plasma during a DC #sputtering process.
The argon ions inside the plasma are accelerated by a high voltage (multiple hundred volts) and collide with the metal target. These impacts throw out some atoms of the target, which then get deposited on the small substrates you can see at the bottom. That way you can create thin metal layers with just a few hundred nanometer thickness or less.
Phase change memory is a type of nonvolatile memory that utilizes the capability of phase change materials (PCM) to transition between an amorphous state, where atoms are scattered, and a crystalline state, where atoms are closely aligned. This change produces a reversible electrical property that c
This method offers a solution for those working on #QuantumTech hardware, as it presents a new alternative to chemical-based copper plating. The procedure is simple and efficient and leads to a uniform metal coating. #Sputtering
The magnetron-sputtered coating in our preprint did not show delamination from the glass substrate, even at a critical load of 60 N. This demonstrates the strong adhesion thanks to the unique surface structure created by the laser. #SurfaceEngineering

Our team at #Matfyz Charles University, #HiLASE Centre & #CVUT have collaborated to bring this innovation to life using laser microstructuring at ambient conditions. The result is a thick layer of the metal film with high adhesion strength & low surface roughness.
This method offers a solution for those working on #QuantumTech hardware, as it presents a new alternative to chemical-based copper plating. The procedure is simple and efficient and leads to well-defined grains and grain boundaries in the metal film. #Sputtering
