The fun fact about #LK99 is that the basic ingredient should be (IMHO) easy to find in corroded lead acid batteries used in generic cars.

BTW, today it has been reported (on Twitter/X - not referenced here) that Department of condensed matter at the Faculty of Mathematics and Physics of Charles' University, Prague #praha #matfyz is attempting their own #LK99 synthesis! #alchemy

So stay tuned for ongoing room temperature superconductor rush 😉

Excited to share our latest preprint on #LaserAssisted Two-Step Glass Wafer Metallization! A simple & efficient solution for improved compatibility between glass & metallic films. #MaterialsScience
https://dx.doi.org/10.2139/ssrn.4343362

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 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

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 of the metal film to the glass substrate, thanks to the unique surface structure created by the laser. #SurfaceEngineering

This method of glass metallization will be a game-changer for those in the field of high-frequency electronic devices. The preprint outlines a practical solution for the realization of glass-based circuit materials, offering a more cost-effective alternative to chemical-based copper plating.
