A Thirty-Year Gap: Reviving All-Nitride Glasses as Processable, High-Performance Materials. [PDF]
Adv Sci (Weinh)Oxygen‐free all‐nitride glasses are revisited in light of new avenues of synthesis, raw material availability, and applications. A semi‐empirical analysis predicts mechanical performance achieving the level of engineering ceramics while maintaining visual transparency, and significant potential regarding optical properties into the infrared spectral ...

Development of Hydrogen-Free Diamond-Like Carbon Coating for Piston Rings
Tribology Online, 2017 The first piston ring application of a hydrogen-free diamond-like carbon (H-free DLC) coating to a mass-production gasoline engine reduces friction. It is found that the friction reduction effect between the cylinder bore and piston is 18%.
