Mathematical Model of Piston Ring Sealing in Combustion Engine
Polish Maritime Research, 2015 This paper presents a mathematical model of piston-rings-cylinder sealing (TPC) of a combustion engine. The developed model is an itegrated model of gas flow through gaps in TPC unit, displacements and twisting motions of piston rings in ring grooves as ...

Non-equilibrium dynamics of the piston in the Szilard engine
, 2018 We consider a Szilard engine in one dimension, consisting of a single particle of mass $m$, moving between a piston of mass $M$, and a heat reservoir at temperature $T$. In addition to an external force, the piston experiences repeated elastic collisions

Advanced Healthcare Materials, EarlyView.The pyrogallol‐conjugated carboxymethylcellulose (CMC‐PG) hydrogel is applicated as a filler for the treatment of presbylaryngis, a vocal fold atrophy. CMC‐PG provides a bulking effect to the vocal folds. CMC‐PG is readily injectable and tissue adhesive, enabling sustained release of growth factor over long period.

The Promise of Solid Lubricants for a Sustainable Future
Advanced Materials, EarlyView.Lubricants are vital for technology, saving energy and resources. The industry seeks sustainable solutions beyond fossil fuels. Solid lubricants offer extremely low friction and reduce environmental impact, especially in harsh conditions. Can these solids truly replace liquid lubricants, or are they limited to extreme applications?
