Interfacial solar steam generation (ISSG) has recently received much attention as a low-carbon-footprint and high-energy-efficient strategy for seawater desalination wastewater treatment. However, achieving the goals of high evaporation rate, ecofriendliness, tolerance to salt ions in brine remains bottleneck. Herein, novel hydrogel-based evaporator effective was synthesized on basis sodium alginate (SA) carboxymethyl chitosan (CMCS) incorporating carbon nanotube (CNT)-wrapped melamine...

Organic cathode materials are widely considered as highly promising for aqueous zinc-ion batteries (AZIBs) due to their tunable properties, low cost, and ease of processing synthesis. Benzothiadiazoles have demonstrated significant potential organic electrode in AZIBs, owing strong electron-accepting capabilities the presence multiple reversible redox sites anthraquinone. In this study, we designed a polymer, poly(2-methyl-6-(7-methyl-5,6-dinitrobenzo[

To explore the key factors on stimuli-responsive behavior of polyamides (PAs), TPA-7-BPT series with TPA-12-BPT for comparison were synthesized by polycondensation two kinds diamines containing benzophenothiazine (BPT) groups fused to triphenylamine (TPA) at different positions and various dicarboxylic acid monomers, respectively. PAs exhibit significant multi-stimuli-response stimulus sources such as 2,4,6-trinitrophenol (TNP), acid, voltage, light. The photoluminescence (PL) TPA-7-BPT-CA...
