The increasing concern over environmental pollution from brake dust and the adverse impacts of conventional brake pad materials, such as metallic, semi-metallic, and ceramic composites, has prompted the exploration of more sustainable alternatives. Traditional brake pads release harmful non-exhaust emissions that contribute to air pollution and wear down quickly, posing both environmental and operational challenges. This study investigates the development and performance evaluation of polymer friction composites enhanced with natural friction modifiers sourced from agricultural waste materials like walnut shell, coconut shell, and groundnut shell powders.

Introduction: Not all wound patients are candidates for surgical debridement. A felted, reticulated open cell foam with an array of 10 mm holes (VFCC) for use with instillation therapy has been used to eliminate non-viable tissue from patient wound beds. The mechanisms for this have not been fully elucidated.

Astringency is a complex oral sensation characterized by dryness and constriction in the mouth. It is typically induced by polyphenol-rich foods and beverages such as wine and tea. The quantitative assessment of astringency intensity has become a prominent research focus in the food science field.

This study introduces a novel heuristic phenomenological model for analyzing the evolution of contact areas on rough surface. Contrasting with traditional methods, it employs a cut-off threshold approach to track numerical and topological metrics across different deformation stages. The model quantifies contact area distributions, nested sub-regions, and self-affine parameters, revealing universal trends across scales spanning nanometers to kilometers.

This study investigates the impact of a sweetened acidic beverage, an apple juice (J) consumption on the tribological properties, viscoelasticity, and protein concentration/ composition of human saliva. Using a combination of tribological measurements, quartz crystal microbalance with dissipation monitoring (QCM-D), and protein analysis, we assessed how J may affect saliva's lubricating behaviour and adsorbed salivary film characteristics compared to water (control). Tribological results revealed that saliva (collected from 32 healthy adults) exposed to water or J exhibited increased friction when compared to unstimulated whole mouth saliva (uWMS), particularly within the boundary lubrication regime.
