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...

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...

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)...

Abstract This study presents the first application of a lab-scale Sponge-Membrane Bioreactor (Sponge-MBR) for treating wastewater containing 3,4-dichlorophenol (3,4-DCP). The effects of hydraulic retention time (HRT) were initially evaluated at three levels (5, 10, and 15 h) to identify an optimal operating condition based on chemical oxygen demand (COD) and 3,4-DCP removal performance. Accordingly, an...

Abstract Camellia Chrysantha (Hu) Tuyama (CCT) is a valuable medicinal herb containing bioactive compounds with inhibitory activities against 3CLpro/Mpro of COVID-19. In this study, silver nanoparticles (AgNPs) were synthesized using the aqueous extract of CCT, and the role of CCT compounds in nanoparticle formation was investigated through combined experimental and computational approaches. Specifically, twelve major...

Abstract This study explores the crack opening dynamics in Mode-I fracture of pre-stretched viscoelastic elastomer sheets under varying strain energy release rate (Γ). The degree of viscoelasticity was widely tuned by altering the mixing ratio of telechelic precursor chains and a tri-functional cross-linker, producing elastomers with different amounts of relaxation components such as dangling chains...
