The simultaneous detection and removal of Ag from drinking water was crucial for preventing human health, while it was also extremely challenging due to bifunctional materials that combine both Ag adsorption and detection functions rarely being explored. In this study, a benzotrithiophene-based covalent organic framework (TAPA-BTT) was synthesized and applied to detect and remove Ag. TAPA-BTT exhibited high crystallinity, a large specific surface area, and good thermal stability.

Thorium-227 (Th) is an α-emitting radionuclide currently under investigation for targeted alpha therapy. Available chelators used for this isotope suffer from challenging multistep syntheses. Here, we present the synthesis and preclinical evaluation of a novel bifunctional chelator, SCN-Bn-DOTHOPO, which contains an isothiocyanate group that is suitable for conjugation to biological molecules.

"Green chemistry" describes the development of new technologies that reduce or eliminate the need for hazardous compounds or the production of them. In order to accomplish this goal, we have developed a new magnetic recyclable biocatalyst in this study by successfully applying aspartic acid to magnetic nanoparticles. Aspartic acid's molecular makeup made it possible for it to stabilize on magnetic nanoparticles using a straightforward method.

Article Synopsis
- Proton exchange membrane fuel cells (PEMFCs) face challenges due to the limitations of Nafion membranes, which can degrade when exposed to strong oxidizers, prompting the need for new stable proton-conductive materials.
- A novel material, Htimb-based PMo-based POMOFs (CUST-577), was synthesized, demonstrating excellent proton conductivity and longevity, with a proton conductivity of 8.9 × 10 S cm at 80 °C and 98% relative humidity.
- CUST-577 also showed impressive capacitance properties in a three-electrode system, with a high specific capacitance of 308 F/g and strong retention after extensive cycling, indicating its potential

Dysfunction in the SHP1 enzyme can cause cancers and many diseases, so it is of great significance to develop novel small molecule SHP1 inhibitors. Through continuous monitoring of metabolic and targeted processes of SHP1 inhibitors in real-time, we can evaluate the effectiveness and toxicity of the inhibitors, further optimize drug design, and explore SHP1 biology. Indoloquinoxaline is an important class of N-containing heterocycle, which has been studied and applied in the pharmacological field and in optoelectronic materials.
