The development of fluorescent probes for detecting nerve agents has been the main concern focus research because their lethal toxicity humans. Herein, a probe (PQSP) based on quinoxalinone unit and styrene pyridine group was synthesized could visually detect sarin simulant diethyl chlorophosphate (DCP) with excellent sensing properties in solution solid states. Interestingly, PQSP showed an apparent intramolecular charge-transfer process by catalytic protonation after reacting DCP methanol,...
Zirconium-based metal–organic frameworks (Zr-MOFs) have been considered as prospective materials for the degradation of nerve chemical warfare agents (CWAs) but show poor catalytic performance toward blister agents. Moreover, powder issues and adsorption capability also remain major challenges application Zr-MOFs in practical CWA detoxification. Herein, a series defected granular UiO-66-NH2 gels are synthesized via adjusting amount added concentrated hydrochloric acid decontamination...
Photoluminescence efficiencies of covalent organic frameworks (COFs) are significantly restricted by electron delocalization and charge transfer among the conjugated skeletons. Two nanofilms using tetraphenylethylene benzo[c][1,2,5]thiadiazole as building blocks were facilely prepared via an interfacially confined condensation strategy. The distinct dipole moment orientations imine linkages involved in π-delocalization donor-acceptor systems diversely. They also played critical roles...
Zirconium-based metal-organic frameworks have emerged as promising materials for detoxifying chemical warfare agents (CWAs) due to their remarkable stability and porosity. However, practical application is hindered by issues with powder form poor catalytic performance in solid-phase degradation. To address these challenges, herein, a granular MOF-808 gel (G808) prepared under optimized conditions degradation of the simulant 2-chloroethyl ethyl sulfide (2-CEES), blister agent, neat state...
Mustard gas (HD) is a well-known chemical warfare agent, recognized for its extreme toxicity and severe hazards. Metal–organic frameworks (MOFs), with their unique structural properties, show significant potential HD adsorption applications. Due to the hazards of HD, most experimental studies focus on simulants, but molecular simulation research these simulants remains limited. Simulation analyses can uncover structure–performance relationships enable validation, optimizing methods,...
High temperature and humidity conditions can lead to metabolic disorders in the human body, equipment corrosion, bacterial growth. Therefore, development of efficient, reusable, biofriendly dehumidifying materials is urgently needed. For this purpose, we developed a humidity-sensitive polyacrylamide composite hydrogel film aimed at effectively regulating skin surface temperature, which enhanced comfort thermal safety high-temperature environments. Comprising poly(vinyl alcohol),...
Pistacia Chinensis is a potential and suitable non-edible feedstock for biodiesel production in China. In the present paper, three extraction methods to obtain seed oil of were compared Soxhlet was found as most effective one. Two kinds biodiesels produced catalyzed homogeneously by sodium hydroxide from crude Hebei province Jiangsu province. Fourier transform infrared spectroscopy used compare alterations functional groups oils their products after transesterification, gas...
For the first time, we report hierarchically porous monolithic UiO-66-X xerogels for ultra-fast destruction of chemical warfare agents. The half-lives vesicant agent sulfur mustard (HD) and nerve VX are as short 14.4 min 1.5 min, respectively.
Rhodamine phenol-based fluorescent probes have been synthesized. The probe <bold>RBNP </bold>demonstrates a rapid response and extreme low limit detection to diethylchlorophosphate can rapidly visually detect real nerve agent GB in vapor.
Chemical protective clothing (CPC) is major equipment to protect human skin from hazardous chemical warfare agents (CWAs), especially nerve and blister agents. CPC performance mainly dominated by the material, which needs meet various requirements, such as mechanical robustness, properties, physiological comfort, cost-effectiveness, dimensional stability. In this study, polyvinylidene fluoride (PVDF) based sodium sulfonate membranes with different ion exchange capacities (IECs) are prepared...

This study...
To improve the poor thermal conductivity of microencapsulated phase change materials (MPCMs), a strategy was designed with effective combinations between graphene nanosheets (GNs) and shells to prepare thermally conductive MPCMs–GNs by using cellulose nanofibers (CNFs) assist GN dispersion. The experiments theoretical calculations both illustrated that CNFs effectively prevented GNs from aggregating due strong Van der Walls interactions GNs. morphologies structures MPCMs without were...
