Summary: In this study, the electrochemical performance of Zn metal anode in aqueous batteries was improved by modifying the conventional filter paper separators with chitosan. The chitosan coating allowed preferential adsorptions of proton, zinc ion and sulfate, which suppressed corrosions and hydrogen evolution reactions at Zn electrode. The interactions of zinc ion and sulfate with chitosan regulated the ion transport manner and ensured homogeneous Zn nucleation and growth. With the use of chitosan modified separators, the Zn electrode showed a long cycle life of 2900 h and a high coulombic efficiency of 99.6%. The capacity retention of Zn||MnO2 batteries was also significantly enhanced from 52.8% to 98.4% over 1000 cycles.

Summary: A fluorinated separator interface (PVDF@GF) is constructed by grafting polyvinylidene difluoride (PVDF) onto the graphene surface, enabling high-performance aqueous zinc ion batteries (AZIBs). The strong interaction between CF bonds in PVDF and Zn2+ ions allows for evenly redistributed Zn2+ ions at the electrode interface and faster Zn transportation kinetics, resulting in homogeneous and fast Zn deposition. The electronegative separator interface repels SO42- ions and anchors H+ ions, reducing passivation and corrosion. The PVDF@GF-based Zn|Zn symmetric cell exhibits superior cycling stability and the Zn|VOX full cell demonstrates high capacity retention after multiple cycles, providing new insights for the design of advanced separators for stable and reversible Zn metal anode chemistry.

Summary: A novel bifunctional electrolyte additive thiourea (TU) was introduced to improve the reaction kinetics and cycle stability of aqueous zinc-sulfur (Zn-S) battery. TU can undergo reversible redox reactions, enhancing the reversibility between ZnS and S and providing extra capacities. The mechanism of TU on the S@KB electrode was proposed, involving the interaction between TU intermediates and ZnS to weaken the Zn-S bonds and inhibit the formation of irreversible by-product. The S@KB electrode exhibited excellent cyclic performance with low decay rate of 0.11% per cycle after 300 cycles at 5 A/g.

Summary: We developed a pH-sensitive growth mechanism to form in situ protective layers using glutaric acid (GA) and Zn2+ in the electrolyte solution. By deprotonating GA additives and integrating them with Zn2+ coordination, a thin Zn glutarate layer was formed to prevent hydrogen evolution reaction (HER) and Zn hydroxide sulfate hydrate (ZHS) precipitation. The study demonstrated the effective formation of Zn-organic protective layers for long-term cycling.

Summary: Antibiotic resistance (AR) is a significant environmental hazard in the current age. Antibiotic resistance genes (ARGs) are the fundamental units that spread AR in the environment, potentially transferring from non-pathogenic to pathogenic microbes. China, as the largest producer and consumer of antibiotics, poses a potential threat of developing superbugs and disseminating ARGs. This review comprehensively examines ARGs in China's drinking water sources, evaluating their origin, influencing factors, and the risk posed. It also outlines mitigation strategies. The findings of this review can help policymakers and scientists address this problem urgently.

Summary: Climate warming enhances the threat of antibiotic resistance genes (ARGs) to public health, and this study investigates the relationship between temperature and resistome in a water environment. The results show that temperature significantly influences ARG profiles and diversity, with certain ARGs and mobile genetic elements (MGEs) being sensitive to temperature. High-risk ARGs and opportunistic pathogens are positively correlated with temperature, indicating a potential increase in these biological or genetic pollutants under global warming. This study reveals the predictability of temperature on antibiotic resistance genes and provides a suitable approach to track their fate and spread in water environment under climate warming.

Summary: The relationship between putrescine, cadaverine, and antibiotic resistomes in animal carcass decay is still unclear. Through laboratory simulation experiments, the effects of excess putrescine, cadaverine, and a mixture of both on antibiotic resistance genes (ARGs) and microbiome in aquatic environments were investigated. The results showed that putrescine and cadaverine increased the total carbon and nitrogen levels in water and sediment. In addition, the abundance of mobile genetic elements and ARGs in water was higher than in sediment under the exposure of putrescine and cadaverine. The alpha diversity of microbial communities in water and sediment was significantly reduced by putrescine and cadaverine, while the microbial community structures were also greatly affected. Moreover, putrescine and cadaverine led to an increase in high-risk ARGs and opportunistic pathogens in sediment, promoting the prevalence of antibiotic resistant bacteria. Overall, our findings provide important insights into the impact of main metabolites in carcass decay on microbiome and resistomes, and offer references for risk assessment and pollution management.

Summary: By using in situ transmission electron microscopy and in situ X-ray diffraction, it has been discovered that the irreversible conversion of NiCoP@C in sodium-ion batteries is caused by the rapid migration of P in the carbon layer and preferential formation of isolated Na3P during discharge. The modification of the carbon coating layer inhibits the migration of Ni/Co/P atoms, resulting in improved initial coulombic efficiency (ICE) and cycle stability. This inhibition of fast atom migration could be applied to various electrode materials and guide the development of advanced sodium-ion batteries.

Summary: The cathode electrolyte interphase (CEI) layers, derived from the oxidative decomposition of electrolyte, can protect the cathode surface and prevent contact with the electrolyte. The CEI layer consists of an inorganics-dominated inner solid electrolyte layer (SEL) and an organics-rich outer quasi-solid-electrolyte layer (qSEL), which merge without a clear boundary. However, the traditional characterization method can dissolve the qSEL and destroy the SEL, leading to overanalysis and misassignment of CEI architecture. In this study, we established a comprehensive characterization paradigm and successfully reconstructed the original CEI layer model using various technology.

Summary: This study analyzed the levels, sources, and hazards of heavy metals (HMs) and magnetic minerals in street dust and sand-dust storm from Dunhuang, an extremely arid city in northwest China. The results showed that HM enrichment levels in street dust were higher than in urban topsoil and background values, with both natural and anthropogenic sources. Magnetic parameters indicated the presence of pollutants containing coarse pseudo single-domain and multidomain ferromagnetic minerals. Industrial and traffic emissions were major sources of HMs, while coal mining and combustion contributed to the presence of Pb and Co. The ecological and non-carcinogenic risks of HMs were moderate, with Cd being the main driver of risk.

Summary: Based on previous work, this study reveals a fundamental difference in the decomposition pathway of the electrolyte under XFC conditions compared to the enhanced reactivity between the oxide and electrolyte caused by Ni content. The presence of Ni catalyzes solvent dehydrogenation, leading to the formation of protic species that can attack the intermediate, PF5, thereby promoting the decomposition/hydrolysis of LiPF6. However, in XFC conditions, the reaction time of dehydrogenation conducted at high voltages is significantly reduced, while conversion of LiPF6 to PF5 lasts throughout the discharging process. Greater accumulation of PF5 as a new initiator changes the solvent decomposition pathway, leading to different cathode-electrolyte interface layers.

Summary: When an ionic crystal dissolves in a solvent, the associated positive and negative ions are released. However, the understanding of the form, interaction, and dynamics of ions in real solution is limited due to experimental challenges. Using liquid phase transmission electron microscopy, we observed the diffusion and aggregation of POM ions in water. Real-time observation revealed unexpected local reciprocating hopping motion of ions, possibly due to short-range polymerized bridges of water molecules. Ion oligomers in dilute solution undergo frequent splitting, aggregation, and rearrangement, indicating weak counterion-mediated interaction. Furthermore, POM ions with tetrahedral geometry exhibit directional interaction and structure-dependent dynamics compared to spherical ions.
