Powder-based fire extinguishing agents have become a kind of promising substitutes for halon extinguishing agents in civil aircrafts. However, their storage lifespan, significantly influenced by the thermal aging, emerges as a crucial yet overlooked aspect for aviation use. This study investigates the effects of thermal aging cycles on various parameters of ordinary dry powder extinguishing agent (ODPEA) and novel superhydrophobic and oleophobic ultra-fine dry powder extinguishing agent (SHOU DPEA), including surface microscopic morphology, D90 (the diameter at which 90% of the cumulative volume of particles are equal to or smaller than this value), chemical structure, hydrophobic and oleophobic angles, flowability, extinguishing time and effectiveness.

Hepatocellular carcinoma (HCC) is the most prevalent form of primary liver cancer, notoriously refractory to conventional chemotherapy. Historically, sulfane sulfur-based compounds have been explored for the treatment of HCC, but their efficacy has been underwhelming. We recently reported a novel sulfane sulfur donor, PSCP, which exhibited improved chemical stability and structural malleability.

Potency optimization of macrocyclic peptides can include both modifying intermolecular interactions and modifying the conformational stability of the bioactive conformation. However, the number of possible modifications is vast. To identify modifications that enhance the stability of the binding conformations in a cost-effective manner, there is a need for a high-throughput in-silico method that scores the conformational stability of these modified molecules.

Formamidopyrimidine DNA glycosylase (Fpg) and flap endonuclease 1 (FEN1) are essential to sustaining genomic stability and integrity, while the abnormal activities of Fpg and FEN1 may lead to various diseases and cancers. The development of simple methods for simultaneously monitoring Fpg and FEN1 is highly desirable. Herein, we construct a multiple cyclic ligation-promoted exponential recombinase polymerase amplification (RPA) platform for sensitive and simultaneous monitoring of Fpg and FEN1 in cells and clinical tissues.

Recently, multi-enzyme cascade catalysis has attracted increasing attention due to the advantages of integrating multiple enzymes, few side reactions and high catalytic efficiency. Herein, a novel dual-enzyme cascade system (GOx-FMt-HRP) was developed through cofactor-directed orientational co-immobilization of glucose oxidase (GOx) and horseradish peroxidase (HRP) onto functional montmorillonite (FMt). The presented method realizes the reconstitution of cofactors and apo-enzymes (enzymes without cofactors), which enables enzymes to be immobilized in specific orientations on the support, thereby effectively reducing changes in their conformation.
