Summary: A double-wrapped binder with high Young's modulus polyacrylic acid (PAA) inside and low Young's modulus bifunctional polyurethane (BFPU) outside has been designed to address large inner stress of silicon anode during cycling. The binder utilizes a gradient distribution strategy to dissipate stress, with PAA as a protective layer and BFPU as a buffer layer, ensuring the integrity of the silicon anode and enhancing cycling life.

Summary: Stainless steel alloys are commonly used in biomedical applications but surface degradation and wear can lead to failure of bioimplants. This research develops a novel approach using high-energy ion implantation to embed a tracer in the alloy for detecting and monitoring degradation. Accelerated and normal immersion tests show a correlation between isotopic tracer releases and material degradation. Electrochemical tests demonstrate similar corrosion resistance between ion-implanted and bare specimens, and cytotoxicity assays show no significant difference. Osteoblast cells cultured on ion-implanted SS316L show an enhancement in osteocalcin production.

Summary: In this study, a low-cost and multi-function electrolyte additive, cetyltrimethyl ammonium bromide (CTAB), is presented to address the challenges associated with zinc anodes in aqueous zinc ion batteries (AZIBs) for large-scale energy storage. CTAB adsorbs onto the zinc anode surface, regulating Zn2+ deposition and inhibiting dendrite formation. It also modifies the solvation structure of Zn2+ to reduce water reactivity and optimize key physicochemical parameters of the electrolyte, enhancing the stability of the electrode/electrolyte interface and promoting reversibility in AZIBs. The use of CTAB in AZIBs shows promise for improving their performance and practicality in large-scale energy storage applications.

Summary: Nickel implanted silicon substrate has the potential for various applications such as infrared detectors, solar cells, spintronic devices, and the synthesis of nickel silicide layer in Si substrates. This study investigates the distribution profile of Ni ions and structural changes before and after annealing process in crystalline silicon substrates implanted with Ni ions. The results show significant changes in the in-depth concentration profile of Ni ions due to the inward and outward diffusion of Ni atoms during the annealing process, and the formation of NiSi2 phase around Ni atoms in the implanted region.

Summary: A novel broad-band excitation yellow phosphor Ba0.985Al4Sb2O12:0.015Eu(2+) (BASO:Eu2+) with high thermal stability (423 K, 94%) and internal quantum efficiency (96.7%) was synthesized by solid-state reaction at high temperatures in air. Structural and spectral analyses revealed that the Eu2+ ions in BASO occupied [BaO8] hexahedra, forming a single luminescence center. This study provides a reliable direction for the facile synthesis of high-performance Eu2+-doped phosphors in air.
