Lithium-ion batteries (LIB) have developed into the mainstream power source of energy storage devices due to their advantages: high power density, high power, long service life, and less pollution. This materials development for LFP batteries was considered successful in synthesizing powder. Here we show that three synthesis conditions were performed. LFP doped NiO, NMC, and (NH4)2HPO4 were synthesized by the nitrogen gas flow method. LFP-doped NiO was burned at 600 °C and 700 °C for five h. NMC doped with LFP burned at 550 °C for five h, and NMC-doped LFP and (NH4)2HPO4 were burned at 550 °C and 600 °C for five h. The structure and morphology of the material were examined by X-ray diffraction (XRD) and scanning electron microscopy (SEM). © 2022

Hydrogen-treated CoCrMo alloy: a novel approach to enhance biocompatibility and mitigate inflammation in orthopedic implants

In recent decades, orthopedic implants have been widely used as materials to replace human bone tissue functions. Among these, metal implants play a crucial role. Metals with better chemical stability, such as stainless steel, titanium alloys, and cobalt-chromium-molybdenum (CoCrMo) alloy, are commonly used for long-term applications. However, good chemical stability can result in poor tissue integration between the tissue and the implant, leading to potential inflammation risks. This study creates hydrogenated CoCrMo (H-CoCrMo) surfaces, which have shown promise as anti-inflammatory orthopedic implants. Using the electrochemical cathodic hydrogen-charging method, the surface of the CoCrMo alloy was hydrogenated, resulting in improved biocompatibility, reduced free radicals, and an anti-inflammatory response. Hydrogen diffusion to a depth of approximately 106 ± 27 nm on the surface facilitated these effects. This hydrogen-rich surface demonstrated a reduction of 85.2% in free radicals, enhanced hydrophilicity as evidenced by a decrease in a contact angle from 83.5 ± 1.9° to 52.4 ± 2.2°, and an increase of 11.4% in hydroxyapatite deposition surface coverage. The cell study results revealed a suppression of osteosarcoma cell activity to 50.8 ± 2.9%. Finally, the in vivo test suggested the promotion of new bone formation and a reduced inflammatory response. These findings suggest that electrochemical hydrogen charging can effectively modify CoCrMo surfaces, offering a potential solution for improving orthopedic implant outcomes through anti-inflammatory mechanisms. © 2024 The Royal Society of Chemistry.

Quaternary Ammonization Treatment Enhances the Antifouling Activities of the Capsaicin-Based Polybenzoxazine Coatings

SSRN

作者： Yang, Hao Liu, Yi Chen, Hao Li, Hua Zhejing-Japan Joint Laboratory for Antibacterial and Antifouling Technology Zhejiang Engineering Research Center for Biomedical Materials Cixi Institute of Biomedical Engineering Ningbo Institute of Materials Technology and Engineering Chinese Academy of Sciences Ningbo315201 China Department of Mechanical Materials and Manufacturing Engineering University of Nottingham Ningbo China Ningbo315100 China Center of Materials Science and Optoelectronics Engineering University of Chinese Academy of Sciences Beijing100049 China

Marine biofouling is an important factor that affects the service life of marine equipment. Benzoxazine is a thermosetting resin with flexible molecular design and waterproof properties, which has great potential for the marine antifouling applications. In this work, phenol source capsaicin mimicking N-(4-hydroxy-3-methoxy-benzyl) acrylamide (HMBA), two amine sources 3-aminopropyltriethoxysilane (APTES) and furfurylamine (FFA) together with paraformaldehyde were used for preparing two benzoxazine coatings HMBA-APTES (HA) and HMBA-FFA (HF). By reacting with iodomethane, quaternary ammonium group was introduced into the N-position of oxazine ring. The quaternary ammonified benzoxazine coatings HMBA-APTES-IM (HAI) and HMBA-FFA-IM (HFI) show exciting antibacterial performance as compared to the untreated benzoxazine coating. In particular the HFI coating exhibited 93.8%, 96.4%, 99.9%, and 99.9% killing rates for E Coli, S. aureus, P. aeruginosa, and B. subtilis, respectively. The quaternary ammonization treatment also brought about further enhanced anti-algae activity and excellent real-sea antifouling performances. However, introduction of the ionic groups hindered the thermal polymerization process of benzoxazine, leading to more defects on the coating surface, resulting in poorer corrosion resistance than HA and HF as detected from electrochemical corrosion and neutral salt spray experiments. The corrosion current density of the P(HA) and the P(HF) coatings is two orders more than that of the P(HAI) and the P(HFI) coatings. Our results would shed light on developing new quaternary ammonization treatment routes for polymeric coatings for desired functions. © 2024, The Authors. All rights reserved.

Due to extraordinary electronic and optoelectronic properties, large-scale single-crystal two-dimensional (2D) semiconducting transition metal dichalcogenide (TMD) monolayers have gained significant interest in the development of profit-making cutting-edge nano and atomic-scale devices. To explore the remarkable properties of single-crystal 2D monolayers, many strategies are proposed to achieve ultra-thin functional devices. Despite substantial attempts, the controllable growth of high-quality single-crystal 2D monolayer still needs to be improved. The quality of the 2D monolayer strongly depends on the underlying substrates primarily responsible for the formation of grain boundaries during the growth process. To restrain the grain boundaries, the epitaxial growth process plays a crucial role and becomes ideal if an appropriate single crystal substrate is selected. Therefore, this perspective focuses on the latest advances in the growth of large-scale single-crystal 2D TMD monolayers in the light of enhancing their industrial applicability. In the end, recent progress and challenges of 2D TMD materials for various potential applications are highlighted. © 2023 The Authors. Advanced science published by Wiley-VCH GmbH.
