"polymer adhesives in chip/ optical fiber connection cracks in extreme cold, degrades under radiation/ heat, fails in vacuum, overcome using hydroxide catalysis bonding creating glass-like molecular bond... quantum computing systems (ultracold + vacuum), space missions, nuclear reactors, industrial/ energy applications... limitation: bonding currently takes several days, but with engineering likely sped up for mass production... high-speed, energy-efficient photonic chip operation in extreme environments"
