Chemical-Physical Synergistic Assembly of MXene/CNT Nanocoatings in Silicone Foams for Reliable Piezoresistive Sensing in Harsh Environments.

Owing to their high sensitivity across a wide stress range, mechanical reliability, and rapid response time, flexible polymer foam piezoresistive sensors have been extensively used in various fields. The reliable application of these sensors under harsh environments, however, is severely limited by structural devastation and poor interfacial bonding between polymers and conductive nanoparticles. To address the above issues, robust MXene/CNT nanocoatings on the foam surface, where the chemical assembly of MXene nanosheets and the physical anchoring of CNTs lead to strong interfacial bonding, are designed and described, which endows foams with structural reliability and unexpected multi-functionalities without compromising their instinct properties.

Facile and Efficient Synthesis of Fluorosilicone Polymers by Using an Optimized Gradient Ring-Opening Reaction.

Fluorosilicone rubber is essential for sealing in extreme temperatures and non-polar environments due to its exceptional adaptability. However, achieving a high yield of fluorosilicone polymers with medium and high fluorine content remains a challenge. Herein, a facile gradient strategy is developed that involves modifying the method of cyclic monomer addition based on the rate of ring-opening polymerization (ROP), to improve yield and adjust fluorine content precisely.

A novel "target constituent knock-out" strategy coupled with TLC, UPLC-ELSD and microcalorimetry for preliminary screening of antibacterial constituents in Calculus bovis.

A novel "target constituent knock-out" strategy was proposed and applied for preliminary screening of antibacterial constituents in Calculus bovis (C. bovis). This strategy was accomplished through the following steps: (1) the single constituents (A-F) in C.
