Lubrication Modeling of the Reciprocating Piston with High Lateral Load and Various Conditions in a Swash Plate-Type Piston Pump

Lubricants
Most asymmetrical lateral forces occur in the reciprocating piston mechanism, which is widely applied as a major component of power equipment. When this lateral force greatly acts on the piston, it comes into contact with the cylinder.

Effect of UHMWPE Incorporation on the Tribological Performance of Carbon Fiber‐Reinforced PEEK Nanocomposites

Journal of Applied Polymer Science, Volume 143, Issue 44, November 20, 2026.
UHMWPE provides interfacial lubrication, improving tribological performance of PEEK‐based sliding bearing bushings. ABSTRACT Ultra‐high molecular weight polyethylene (UHMWPE) was incorporated into a PEEK‐based hybrid material as a lubrication additive to improve the friction and wear performance of the composite due to its superior lubricity ...

Analysis of Under-Lubricated Condition for Journal Bearing with Coupled Tribological Behavior

Lubricants
Journal bearings are prone to failure due to lubrication state degradation under extreme operating conditions. To address the unclear transition mechanism and undefined state boundaries under insufficient lubrication, a coupled tribological model of ...

Integrated microanatomy and microstructure of the maxillary tooth plate reveal a reinforced feeding system and tougher diet in Late Triassic Hyperodapedontinae (Rhynchosauria, Archosauromorpha)

The Anatomical Record, EarlyView.
Abstract Hyperodapedontine rhynchosaurs possessed a unique oral apparatus, long interpreted as an adaptation for processing abrasive and resistant plant material. However, the microanatomical and histological evidence supporting this interpretation remains poorly documented.

Comparative histological, histochemical, and histometric evaluation of the esophagus in two avian species with different feeding habits (Ciconia ciconia and Buteo buteo)

The Anatomical Record, EarlyView.
Histological structure of esophagus. Abstract The aim of this study was to conduct a comparative evaluation of the histological and histochemical organization of the esophagus in two avian species with different feeding ecologies. A total of 6 individuals were used for this purpose (3 storks, 3 common buzzards).
