Summary: Graphite, a cost-effective and well-developed material, shows promise as an anode material for potassium ion batteries due to its desirable characteristics such as high capacity, tap density, conductivity, and charge curve. However, graphite suffers from capacity fading and poor rate capability. Most research focuses on the electrolyte or binder, aiming for a more robust passivation layer, and modifying graphite directly is not common. This study proposes a strategy of oxidizing graphite to cripple its crystallinity, followed by adjusting coherence length under different pyrolysis temperatures, resulting in improved battery performance.

Summary: Due to its abundant precursors, simple preparation, and environmental friendliness, nitrogen-doped carbon is regarded as a promising anode material for potassium-ion batteries (PIBs). In this study, nitrogen-doped carbon material (NC-2) was synthesized using exfoliated g-C3N4 as a precursor, combined with sucrose, and subjected to hydrothermal and high-temperature pyrolysis. NC-2 exhibited a high nitrogen content, porous layered structure, and large interlayer spacing. As the anode for PIBs, NC-2 demonstrated a high reversible capacity of 261.07 mAh g-1 at 0.1 A g-1 and an impressive rate performance of 153.36 mAh g-1 at 2 A g-1. The excellent performance of NC-2 can be attributed to its porous layered structure, enlarged interlayer spacing promoting ion diffusion, and the presence of abundant active sites due to nitrogen doping. These results indicate the great potential of NC-2 as a PIBs anode material.

Summary: Layered double hydroxides (LDHs) are investigated as anode materials for potassium ion batteries (PIBs), with MgFe-LDH showing higher K+ storage capacity but lower initial Coulombic efficiency compared to MgAl-LDH. The dominant mechanisms for K+ storage in these materials are electrical double layer effect and a faradaic process involving a conversion reaction between Fe3+ and Fe2+. The study suggests the potential of developing LDHs as efficient anode materials for PIBs.

Summary: Most bioadhesives are ineffective on bleeding tissues and postoperative adhesion is a common issue. A three-layer biodegradable Janus tissue patch (J-TP) is developed to efficiently close bleeding wounds, promote clotting, and prevent tissue adhesion. The J-TP's adhesive hydrogel bottom layer forms strong adhesion to bleeding tissues through chemical bonding, while the middle layer improves tensile strength and the top layer prevents postoperative adhesion and inflammation. This J-TP shows promise in the clinical treatment of injured bleeding tissues with inhibited adhesion.

Summary: In this study, a multifunctional decellularized scaffolds (DCS)-based vascular patch with improved mechanical properties and biocompatibility was designed. The surface of the patch was coated with ammonium phosphate zwitter-ion (APZI) and poly(vinyl alcohol) (PVA) hydrogel, followed by the decoration of a heparin (Hep)-loaded metal-organic framework (MOF) to inhibit blood coagulation and promote vascular endothelialization. The obtained artificial vascular patch showed suitable mechanical properties, good biocompatibility, and blood compatibility. It also demonstrated enhanced proliferation and adhesion of endothelial progenitor cells (EPCs). The results from imaging techniques confirmed the patency of the implanted artificial vascular patch.
