Battery-type faradaic materials are considered a class of promising electrodes for capacitive deionization (CDI) due to their superior ability store ions through redox reactions. However, the desalination potential such electrode has not been fully explored subject accessibility, conductivity, stability, etc. Herein, embedded battery material Ag nanoparticles is designed in capsule-structural units composed graphene and constructed freestanding composite CDI. Particularly, these confined interconnected capsules can be both efficiently accessed by electrolyte rationally protected capsule networks, significantly unlocking as materials. Impressively, optimized Ag-involved anodes achieve an ultrahigh NaCl capacity ≈360 mg g

Abstract Silver (Ag) is deemed a promising anode material for capacitive deionization (CDI) due to its high theoretical capacity and efficient selectivity Cl − . However, the strong volume change during conversion reaction significantly undermines cycling performance of Ag electrode. Additionally, achieving well‐dispersed in active matrix challenging, as electrodes prepared by conventional thermal reduction tend agglomerate. Herein, organic linker confinement strategy proposed, applying metal–organic framework (MOF) chemistry between nodes ligands construct Ag‐based MOF. The uniform dispersion at molecular level, confined matrix, efficiently enhances utilization sites, strengthens interfacial stability Ag. Consequently, Ag‐MOF CDI exhibits an excellent removal 121.52 mg g −1 20 mA 500 L NaCl solution, rate 60.54%. After 100 cycles, retention 96.93% achieved. Furthermore, capture mechanism elucidated through density functional theory (DFT) calculations, ex situ XRD, Raman XPS. This ingenious electrode design can offer valuable insights development high‐performance applications.

Detecting and quantifying mycotoxins using LFIA are challenging due to the need for high sensitivity accuracy. To address this, a dual-mode colorimetric-SERS was developed detecting deoxynivalenol (DON). Rhodium nanocores provided strong plasmonic properties as SERS substrate, while silver nanoparticles created electromagnetic "hotspots" enhance signal sensitivity. Finite element modeling optimized field intensity, Prussian blue generated distinct at 2156 cm-1, effectively reducing background interference. This achieved detection limit of 4.21 pg/mL, 37 times lower than that colloidal gold-based (0.156 ng/mL). Machine learning algorithms, including ANN KNN, enabled precise classification quantification contamination, achieving 98.8% accuracy an MSE 0.57. These results underscore platform's potential analyzing harmful substances in complex matrices demonstrate important role machine learning-enhanced nanosensors advancing technologies.

Abstract Unraveling the fundamental mechanisms of sodium ion adsorption behavior is crucial for guiding design electrode materials and enhancing performance capacitive deionization systems. Herein, optimization systematically investigated through robust d–d orbital interactions within zinc‐doped iron carbide, facilitated by a novel liquid nitrogen quenching treatment. Liquid treatment can enhance coordination number, strengthen interactions, promote electron transfer, shift d‐band center Fe closer to Fermi level, thereby ions energy. Consequently, obtained material achieves superior gravimetric capacity 121.1 mg g −1 attractive cyclic durability. The highly competitive compared vast majority related research works in field deionization. Furthermore, adsorption/desorption are substantiated ex situ techniques, revealing dynamic atomic electronic structure evolutions under operational conditions. This work demonstrates that optimizing via modulation enabled an effective approach developing efficient materials.
