Summary Sodium-ion batteries (SIB) have been becoming a promising candidate for future energy storage and conversion owing to the abundant sodium sources and availability of their featured materials for solving the planet’s sustainability issues, which is recently a global overriding concern. The development of low-cost, sustainable, compatible, and stable anode materials should be parallel driven in coherent with the great efforts dedicated to the cathode materials research. Through the process of surface activation and subsequent heat treatment, herein, we explored a facile and effective in combining both silica and organic components contained rice husks (RH) to synthesize a high-performance C/SiO2 anode...

Abstract Bovine bone-derived hydroxyapatite (BBHAp) has been reported to be a biocompatible and efficient bone graft substitute. In this study, hydroxyapatite (HAp) was produced by combining the cleaning process with alkali and thermal treatment of bovine bone. The calcination temperature was 700°C. The functionality of the BBHAp scaffold as a bone graft substitute was determined by its physicochemical properties and in vitro biocompatibility. Physicochemical properties such as mechanical properties, degradation, ion composition, crystallinity, crystallite size, surface characteristics, and porosity were characterized using several analytical tools, including X-ray diffraction analysis (XRD), Fourier transform infrared spectroscopy, scanning electron microscopy (SEM), transmission electron...

Abstract Particulate-bound mercury (PBM) plays a critical role in atmospheric mercury (Hg) cycling, yet its complex spatiotemporal variability and potential driving factors remain insufficiently understood, particularly in the Southeast Asia (SEA) region. This study reported year-round (May 2022 to April 2023) data of PBM at an urban (Nguyen Van Cu: 59.81 ± 29.15 pg m−3) and a suburban site (Can Gio: 26.4 ± 9.59 pg m−3) in southern Vietnam. Distinct seasonal trends were observed at both sites, with elevated PBM concentrations in the dry season (November–February), likely driven by changes in the source origin and transport paths of air masses....
