An investigation into the oil transport and starvation of piston ring pack
In order to accurately predict the lubricant film thickness and generated friction in any tribological contact, it is important to determine appropriate boundary conditions, taking into account the oil availability and extent of starvation.

An extended Elrod-Adams model to account for backpressure and blow-by inception [PDF]
The Piston-Ring-Liner system is the main tribological component of internal combustion engines. The Elrod-Adams model is customarily used to numerically assess the hydrodynamics of different ring designs and liner surface treatments. However, that model does not incorporate the backpressure boundary condition, which in this case corresponds to the ...

Development of multiparametric bioprinting method for generation of 3D printed cell‐laden structures
Abstract The organ transplantation field requires new approaches for replacing and regenerating tissues due to the lack of adequate transplant methods. Three‐dimensional (3D) extrusion‐based bioprinting is a rapid prototyping approach that can engineer 3D scaffolds for tissue regeneration applications. In this process, 3D printed cell‐based constructs,

SAAP‐148 Oligomerizes into a Hexamer Forming a Hydrophobic Inner Core
The highly cationic and hydrophobic antimicrobial peptide SAP‐148 effectively eradicates multidrug‐resistant bacteria, persistent cells, and biofilms without inducing resistance. Its efficiency is likely due to its ability to disrupt bacterial membranes as an oligomer, forming a stable alpha‐helical hexameric bundle with three parallel dimers that ...

Measure solutions of one-dimensional piston problem for compressible Euler equations of Chaplygin gas [PDF]
We are concerned with the one-dimensional piston problem for the compressible Euler equations of Chaplygin gas. If the piston moves at constant subsonic speed to the uniform gas, there exists an integral weak solution for the piston problem, consisting of a shock separating constant states ahead of the piston.

Influence of Pd/AC Catalytic Properties on the Continuous Production of Hydrogen from Formic Acid
A highly efficient palladium/activated carbon (Pd/AC) catalyst, prepared with PdCl₂ and nanopowdered AC via wet impregnation without stabilizing agents, achieves superior Pd dispersion, and doubling hydrogen yields compared to commercial catalysts. This advancement improves durability, minimizes regeneration frequency, and enables scalable hydrogen ...

A Piston-Rotaxane with Two Potential Stripes: Force Transitions and Yield Stresses
We examine a rod piston-rotaxane system, where the positions of several mobile rings on the axle are controlled by an external force acting on one of the rings. This allows us to access the translational entropy of the rings.
