49. Research on micro-grinding performance of 2.5D Cf/SiC composites.

Abstract

In order to improve the micro-grinding quality of 2.5D carbon fiber-reinforced silicon carbide ceramic matrix (2.5D Cf/SiC) composite materials, their characteristics under different grinding parameters were investigated in this study. Firstly, theoretical models for the undeformed chip thickness and micro-grinding force were established. Then, orthogonal and single-factor experiments were conducted using 0.9-mm-diameter micro-grinding tools electroplated with 500# diamond abrasive particles. Through the range and variance analysis of the orthogonal experimental results, the order in which grinding parameters affect the grinding performance of 2.5D Cf/SiC composites was obtained. Single-factor experimental results indicate that the theoretical model of the micro-grinding force shows consistent trends with the experimental results. As the grinding depth ap and the feed speed vw increase, the grinding force, the surface roughness Ra, and surface defects after micro-grinding also increase, indicating that the grinding performance of 2.5D Cf/SiC composites gradually deteriorates. On the contrary, increasing the grinding speed vs can improve their grinding performance. Based on the established theoretical model, the reasons for the variation of grinding force, surface morphology, and surface roughness with grinding parameters were elaborated. This research would supply a basis for understanding the micro-grinding performance and provide guidance for improving the micro-grinding quality of 2.5D Cf/SiC composites. [ABSTRACT FROM AUTHOR]

50. Microenvironment‐Adaptive Metallo‐Polymeric Nanodecoys via Subcomponent Coordination for Bacterial Biofilm Eradication and Immunomodulation.

Abstract

Biofilm‐associated infections pose complex challenges that require addressing the multifaceted requirements of biofilm disruption, bacterial killing, and immunomodulation. In this study, microenvironment‐adaptive metallo‐polymeric nanodecoys (MPNs) are synthesized through one‐pot subcomponent coordination in aqueous solution, effectively eradicating bacterial biofilms and modulating immune response. Within the acidic microenvironment of biofilms, the positively charged MPNs demonstrated the ability to interact with and eliminate bacteria while facilitating a Fenton‐like reaction for efficient eradication of bacterial biofilms. As the local microenvironment shifted from a neutral to a basic state during subsequent tissue healing processes, the MPNs adaptively harness the multiple properties to bind pathogen‐associated molecular patterns, scavenge reactive oxygen species, thereby modulating the immune response, alleviating inflammation, and promoting tissue healing. This study presents an efficient strategy for preparing enzyme‐mimicking materials that closely resemble natural metalloenzymes, and the MPNs offer an efficient alternative to current antibiotic treatments for biofilm‐associated infections.
