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 ...

Absorption of Broadband Low-Frequency Sound Beyond the Thermodynamics Limit: An Acoustic Resonator With Magnetic Bearing. [PDF]
Adv Sci (Weinh)This work presents a magnetic‐bearing acoustic resonator that overcomes the thermodynamics limit of sound absorption. By introducing tunable negative stiffness, it achieves broadband low‐frequency absorption within a compact cavity, far exceeding the performance achievable by classic mass‐tuned designs.

Cavitation induced starvation for piston-ring/liner tribological conjunction. [PDF]
, 2011 The study investigates the mechanism of ring-liner lubrication in the vicinity of the top and bottom dead centres of an internal combustion engine. Predicting lubricant transient behaviour is critical when the inlet reversal leads to thin films and ...

An absolute continuity for positive operators on Banach lattices
International Journal of Mathematics and Mathematical Sciences, 1991 For positive operators on a Banach lattice, absolute contnuity conditions are considered. An operator absolutely continuous with respect to T is compared to sums of compositions of T together with orthomorphisms or in special cases projections ...

Piston rotation and frictional forces between piston and cylinder of piston and motor
Proceedings of the JFPS International Symposium on Fluid Power, 1993 The influence of the piston rotation on the frictional forces between the piston and the cylinder has been studied experimentally for a swash plate type piston pump and motor. In order to measure the rotational speeds of the piston, the capacitance detecting method have been employed for the piston with the slits.
