Summary: Fluorinated solid-state electrolytes (FSSEs) have been widely used in all-solid-state lithium batteries (ASSLBs) due to their good compatibility, wide electrochemical windows, and stable chemical stability. However, challenges such as ionic conductivity, chemical stability, and current limitation hinder the practical application of fluorinated solid electrolytes. This review discusses the development history of FSSEs, analyzes recent advances in improving ion conductivity, chemical stability, and current limit through structural design, interface regulation strategies, etc., and prospects the design requirements for future generations of FSSEs, focusing on simple one-step synthesis methods, room temperature ionic conductivity improvement, and optimization of the electrochemical stability window of FSSEs.

Summary: In this study, a 3D numerical model and quantitative parameters were established to investigate the liquid flow uniformity in a concave-convex bi-polar plate (CCBP) electrolyzer. The simulated velocity field revealed significant non-uniform flow in the CCBP electrolyzer, which was validated by a flow visualization experiment. The residence time distribution (RTD) analysis using the CFD coupled particle tracing method can be applied as a criterion for electrolyzer structure design, operation optimization, and scale-up.

Summary: In recent years, there has been a rapid increase in interest for wearable and stretchable multifunctional sensors. The development of practical and versatile devices has faced challenges in achieving self-healing and adhesion to target objects. This study prepared a hydrogel (LM-SA-PAA) with ultrastretchable, self-healing, self-adhesive, and high-sensitivity sensing capabilities, allowing for conformal contact with the skin during dynamic movements. The hydrogel's excellent self-healing properties arise from its double cross-linked networks, and its adhesion is ensured by the microgel shell formed by alginate. The hydrogel showed strain sensitivity and the ability to detect various human motions and electrocardiographic monitoring, making it a promising option for human-machine interface compatibility and medical monitoring.

Summary: In this work, a method is proposed to find hosts that produce broadband NIR Cr3+ emission by screening Ce3+-doped phosphor hosts, allowing Ce3+ and Cr3+ to occupy the same crystallographic site. A NIR phosphor Ba3Sc4O9:Cr3+ is obtained with an emission peak at 835 nm and a FWHM of 188 nm, where Ce3+ or Cr3+ is accommodated at the same Sc3+ site. By following this method, two broadband NIR phosphors Li3Sc2(PO4)3:Cr3+ (lambda(em) = 1000 nm, FWHM = 223 nm) and Na3Sc2(PO4)3:Cr3+ (lambda(em) = 895 nm, FWHM = 184 nm) are discovered.

Summary: Tin bronze was cladded on bare steel and nickel-plated steel to fabricate bimetallic materials. The interfacial microstructures and infiltrated cracks were investigated. Infiltrated cracks originated from the interface and propagated into the interior of the steel along the grain boundaries. When tin bronze was cladded on nickel-plated steel, a transition layer with BCC-Fe structure was also generated and the infiltrated cracks were eliminated.

Summary: Adsorption of Cd(II) on serpentine was investigated under typical environment conditions, involving common environmental anions and cations. The adsorption was negligibly affected by anion type, but was specifically modulated by cations. Mono- and divalent cations enhanced the adsorption by weakening electrostatic double layer repulsion, while trivalent cations suppressed the adsorption due to competitive adsorption. Fe3+ and Al3+ prevented Cd(II) adsorption by binding surface active sites, forming more stable inner-sphere complexes. This study provides insights into the influence of interfacial ion specificity on Cd(II) adsorption in terrestrial and aquatic environments.
