Published: September 2024

AbstractRechargeable magnesium batteries (RMBs) face with the challenge of interphase passivation between electrolytes and Mg anodes. Compared with ether electrolytes, carbonate solvents possess the superior electrochemical stability at cathode side, but their incompatibility with Mg metal, high viscosity, and desolvation energy barrier restrict their practical utilization in RMBs. Herein, the “unwanted‐impurity” water with high concentration is revisited and employed as multifunctional additive in carbonate electrolyte to improve the reversibility of RMBs. Water additive enables the localized deep eutectic effect, reduces the viscosity of carbonate electrolyte, and improves the Mg ion conductivity. The water molecules also participate the solvation sheath of Mg ions, resulting in the reduction of Mg deposition overpotential and inhibition of parasitic reaction. Furthermore, the co‐intercalated water molecules in V2O5 cathode layers enable the stabilization of intercalation structure and supply of additional magnesiophilic sites. Cooperated with the binder‐decorated Mg powder anode, the propylene carbonate electrolyte with water additive endows Mg||Mg symmetric cells and Mg||V2O5 full cells with satisfactory cycling performance and high‐voltage stability. This work revisits the impact of impurity water and provides a practical strategy for the utilization of conventional low‐cost carbonate electrolyte family, broadening the design and formulation of electrolytes for chlorine‐free and high‐voltage RMBs.

AbstractAqueous flow batteries (AFBs) are promising long‐duration energy storage system owing to intrinsic safety, inherent scalability, and ultralong cycle life. However, due to the thicker (3–5 mm) and heavier (300–600 g m−2) nature, the current used graphite felt (GF) electrodes still limit the volume/weight power density of AFBs. Herein, a lightweight (≈50 g m−2) and ultrathin (≈0.3 mm) carbon microtube electrode (CME) is proposed derived from a scalable one‐step carbonization of commercial cotton cloth. The unique loose woven structure composed of carbon microtube endows CME with excellent conductivity, abundant active sites, and enhanced electrolyte transport performance, thereby significantly reducing polarization in working AFBs. As a consequence, CME demonstrates excellent cycling performance in pH‐universal AFBs, including acidic vanadium flow battery (maximum power density of 632.2 mW cm−2), neutral Zn‐I2 flow battery (750 cycles with average Coulombic efficiency of 99.6%), and alkaline Zn‐Fe flow battery (energy efficiency over 70% at 200 mA cm−2). More importantly, the estimated price of CME is only 5% of GF (≈3 vs ≈60 $ m−2). Therefore, it is reasonably anticipated that the lightweight and ultrathin CME may emerge as the next generation electrode for AFBs.

AbstractThe conventional Slippery Liquid Infused Porous Surface (SLIPS) encounters challenges such as silicone oil leakage and complex manufacturing of rough substrate structures. Thus, it is crucial to develop a lubricant that is highly adaptable and less prone to loss for surface structures; a temperature‐controlled method of infusing oleogel into a superhydrophobic surface (SHS) is presented in this paper. This approach draws inspiration from the characteristics of Nepenthes pitcher plant structures, albeit without the need for intricate pore‐making or nanowire structures. It is demonstrated that this resulting surface has exceptional fog harvesting capability, with a fog harvesting efficiency of 0.3222 g cm−2 min−1, which is twice as high as that of the laser aluminum (Al) sheet (0.1553 g cm−2 min−1). Moreover, the surface exhibits remarkable anti‐icing properties, significantly prolonging the icing time by 21‐fold compared to the pure Al sheet while maintaining a minimal ice adhesion force of only 0.16 N. Additionally, the surface showcases excellent antifouling performance, because contaminated droplets readily slide off without leaving residue. The environmentally friendly and straightforward preparation process ensures that it is suitable for large‐scale industrial applications.

AbstractThe combination of multiple physical properties is of great importance for widening the application scenarios of biomaterials. It remains a great challenge to fabricate biomolecules‐based fibers gaining both mechanical strength and toughness which are comparable to natural spider dragline silks. Here, by mimicking the structure of dragline silks, a high‐performance fluorescent fiber Alg‐TPEA‐PEG is designed by non‐covalently cross‐linking the polysaccharide chains of alginate with AIEgen‐based surfactant molecules as the flexible contact points. The non‐covalent cross‐linking network provides sufficient energy‐dissipating slippage between polysaccharide chains, leading to Alg‐TPEA‐PEG with highly improved mechanical performances from the plastic strain stage. By successfully transferring the extraordinary mechanical performances of polysaccharide chains to macroscopic fibers, Alg‐TPEA‐PEG exhibits an outstanding breaking strength of 1.27 GPa, Young's modulus of 34.13 GPa, and toughness of 150.48 MJ m−3, which are comparable to those of dragline silk and outperforming other artificial materials. More importantly, both fluorescent and mechanical properties of Alg‐TPEA‐PEG can be well preserved under various harsh conditions, and the fluorescence and biocompatibility facilitate its biological and biomedical applications. This study affords a new biomimetic designing strategy for gaining super‐strong, super‐stiff, and super‐tough fluorescent biomaterials.

AbstractDesign and synthesis of highly active and robust bifunctional cathode catalysts for oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) are of vital significance for practical applications of lithium–oxygen (Li–O2) batteries. Herein, a built‐in electric field (BIEF) strategy is reported to fabricate MnTe/MnO heterostructures with a large work function difference (ΔΦ) as a bifunctional cathode catalyst in Li–O2 batteries. The MnTe/MnO heterostructures with nanosheets and microporous structures result in an abundance of exposed active sites and facilitate mass transfer. More importantly, the heterogeneous MnTe/MnO nano‐interface region provides a BIEF that can trigger interfacial charge redistribution, fine‐tune the adsorption energy of oxygen intermediates, and alter the morphology of discharge products to accelerate ORR/OER kinetics. Impressively, the fabricated Li–O2 batteries with MnTe/MnO cathode showcases exhibit excellent electrochemical performances, including low charging overpotential, a high specific capacity of 11930 mA h g−1, and good cycle stability over 350 cycles even with a fixed specific capacity of 500 mA h g−1 at a current density of 500 mA g−1. This work provides an avenue for the rational design of high performance heterostructure electrocatalysts toward practical applications for rechargeable Li–O2 batteries.

AbstractP2‐type Mn‐based layered oxides have emerged as one of the most promising cathode materials for sodium‐ion batteries owing to their advantages of facile preparation and high theoretical capacity. However, challenges such as phase transition and irreversible oxygen release during cycling often lead to rapid structural distortion and the formation of oxygen vacancies, ultimately resulting in rapid capacity decay. Herein, a covalency modulation strategy is adopted to address these challenges and successfully achieved a stable P2‐type Mn‐based layered oxide by introducing strong covalent Ni─O bonds. The robust Ni─O motif plays a crucial role in maintaining the rigidity of transition metal (TM) layered frameworks, which efficiently alleviates the structural distortion and degradation of the coordination environments of local TM sites, thereby achieving durable structural stiffness over extended cycles. In addition, the strong covalent Ni─O bonds can also stabilize the local oxygen environment, effectively suppressing the irreversible oxygen release. Benefiting from these advancements, the as‐designed Na0.6Mg0.15Mn0.7Ni0.15O2 cathode displays a full solid‐solution behavior with a low volume change of only 0.9% and an enhanced reversibility of lattice oxygen redox (OR) reaction. This investigation emphasizes the crucial role of covalency modulation in regulating OR chemistry and structural integrity to achieve high‐energy‐density Mn‐based layered oxides.

AbstractThe development of electrically conductive membranes is essential for advancing future technologies like electronic devices, supercapacitors, and batteries. Newly synthesized doubly interpenetrated 3D‐Cd‐MOF (Metal‐Organic‐Framework) containing angular tetra‐carboxylate is found to display very poor electrical conductivity (10−11 S cm−1). However, it exhibits an exceptional ability to adsorb I2 (I2@Cd‐MOF) which shows increased electrical conductivity of the order of 10−8 S cm−1. Following these results, the Cd‐MOF is integrated into the PVDF‐PVP (Polyvinylidene fluoride‐Polyvinylpyrrolidone) polymeric mixed matrix membrane (MMM) and explores their I2 adsorption capabilities and electrical conductivities before and after I2 adsorption. Four polymeric MMMs with the loading of Cd‐MOF 0, 20, 40, and 50% are tested for their I2 adsorption ability and their respective electrical conductivities. The 50% Cd‐MOF‐loaded MMM is found to exhibit higher adsorption of I2 (685 mg g−1) and significant enhancement in conductivity from 10−11 to 10−4 S cm−1. The raise in the electrical conductivity by 10 million times is attributed to the synergistic interactions between I2, Cd‐MOF, PVDF, and PVP polymers as well as the increase in the concentration of charge carriers (holes) within the frameworks. This work serves as blueprint for controlling charge transfer in MMM to tune their electrical conductivity which opens a large window for advanced device applications.

AbstractAqueous Zn‐ion batteries are promising and efficient energy storage systems owing to their low cost, high safety, and satisfactory capacity. However, the instability of Zn metal anodes, caused by dendritic growth and parasitic side reactions, hinders their practical application. In this study, a nanophase‐separated block copolymer layer that enhances the reversibility of Zn metal anodes is introduced. This layer consists of two components: a high‐performance engineering‐plastic‐based hydrophobic block exhibiting excellent mechanical properties and chemical stability, and a hydrophilic block that significantly improves the interfacial stability of the anode by selectively permeating Zn ions through the separated nanophase channels. Through an improved electrochemical system and scalable fabrication process, this block copolymer provides a feasible approach for the practical application of Zn metal anodes in aqueous energy storage systems.

AbstractINTRODUCTIONSocial connection comprises distinct but interrelated aspects describing how individuals connect to each other. Various measures have assessed multiple aspects of social connection in long‐term care (LTC) home populations, but they use inconsistent terminology, making it unclear what aspects are measured. This scoping review describes how social connection is assessed by measures that have been used in LTC home residents.METHODSThis review followed the Preferred Reporting Items for Systematic reviews and Meta‐Analyses extension for Scoping Reviews (PRISMA‐ScR) guidelines. Two systematic literature searches combining search terms for social connection AND LTC home residents AND measurement properties were conducted in eight electronic databases from inception to April 2022. Included studies reported the development or psychometric testing of measures which assessed social connection in LTC home residents. A content analysis with a deductive‐inductive approach was used to analyze the measures’ content and an adapted Framework Method was used for data management. Findings report each measure's items and the assessed aspects of social connection. Dementia and non‐dementia‐specific measures had content, administration, and scoring compared.RESULTSFrom 8753 records, 58 studies reporting on 14 dementia‐specific and 28 non‐dementia‐specific social connection measures were identified, including complete measures, subscales, and single items. These measures assessed social network (52.4%), social isolation (11.9%), social interaction (47.6%), social engagement (31.0%), social support (33.3%), social connectedness (21.4%), and loneliness (9.5%). A total of 27 (64.3%) of the measures included more than one aspect of social connection. Dementia‐specific measures most often assessed social interaction whereas non‐dementia‐specific measures most often assessed social network, social interaction, and social support. Dementia‐specific measures typically relied on a proxy response, whereas non‐dementia‐specific measures more often used self‐report.DISCUSSIONExisting social connection measures in LTC home settings operationalize seven aspects of social connection and differ according to the target population (dementia or non‐dementia‐specific). These findings will inform future measure selection and development.Highlights

Published: September 2024

AbstractAvailability of safe drinking water is a major concern in many parts of the world. While many filtration units operating on various principles are available to combat this, most require electricity, which may not be consistently available in such areas. In the present study, we have designed and demonstrated a water disinfection system that can operate purely on gravity, without any electricity. For this, a potassium hydroxide modified copper‐impregnated activated carbon (KOH‐Cu‐AC) hybrid was used as a filter medium for disinfection, because it is less expensive, with performance comparable to previously reported hybrids containing silver. To maintain a constant water flow rate under gravity, during disinfection, a Mariotte bottle was used as the reservoir of the contaminated water. Using this and a constant head between the bottle and the treated water exit point, the required water‐filter contact time of 25 min (for decontamination) is maintained in the filter column, regardless of tank‐fill level. The demonstrated lab‐scale system can perform disinfection of simulated contaminated water (with an initial concentration of 104 CFU mL−1 Escherichia coli), for at least 6 h, with a flow rate of 150 mL h−1. The disinfection performance from the gravity‐based filter was further validated with the conventional pump‐driven filter, used for continuous disinfection of drinking water. Equivalence of results between pump‐ and gravity‐driven operations helps us to eliminate the need for power, without any compromise in disinfection efficacy. Finally, copper concentration from treated water (106 ppb at steady state) remains very well within the safe limit (1000 ppb as per USEPA guideline). Hence, the lab‐scale design of gravity‐based packed bed filter will be useful for domestic and community‐based supply of safe drinking water in resource‐constrained areas, because it eliminated electricity requirement of conventional power‐driven systems.Practitioner Points
Cost‐effective KOH‐Cu‐AC hybrid is developed as a disinfection material.
Mariotte bottle used for maintaining constant disinfected water flow rate works without any electrical power supply.
This system can be used for getting on‐spot, continuous disinfected water supply.
The concentration of copper in the treated water is well within the safety limit.
It can be applicable in rural and remote areas (no electric power source) as well as natural calamity‐affected areas.

AbstractBecause of its low‐lying location, urbanization, and inadequate infrastructure, Jakarta (Indonesia) has experienced an increase in annual flooding events, rising from an average of five significant floods per year in the 1990s to over 20 annually (2010–2020). With climate change exacerbating extreme weather events, Jakarta encounters escalating risks of flooding. Although the recurrent flooding is exacerbated by non‐point source (NPS) of pollution such as urban runoff and agricultural discharge that contribute to 40% of total pollutants leading to flood‐related issues in Jakarta, none has investigated this research gap. To reflect its novelty, this work explores the implications of climate change on the annual flooding in Jakarta by focusing on NPS and analyzes their impacts from social perspectives. This work also underscores the implications of flooding on livelihoods, health, and social cohesion in Jakarta. Focus group discussion with affected residents was used to shed light on the coping strategies employed in response to recurrent floods, ranging from community‐based initiatives to reliance on informal networks. The empirical findings show that the implications of flooding extend beyond physical damages. Displacement of communities, loss of livelihoods, disruption of essential services, and increased health risks are among the social impacts experienced by local residents. Vulnerable populations, including low‐income communities residing in informal settlements, bear their consequences. Economic losses from flooding amount to USD 500 million annually, impacting over 1 million residents. However, recent interventions have led to a 15% reduction in peak flood levels and a 20% reduction in flood duration in affected areas. Community resilience has also improved, with a 25% increase in flood insurance coverage and a 20% rise in community response initiatives. Overall, this study highlights that climate change exacerbates annual flooding in Jakarta, significantly impacting vulnerable communities through NPS pollution. Addressing the challenges requires integrated approaches combining effective pollution control, resilient infrastructure, and community engagement to mitigate social and long‐term environmental impacts.Practitioner Points
Climate‐induced flooding disproportionately affects vulnerable communities in Jakarta.
Non‐point source pollution from urban runoff contributes to the severity of flooding in Jakarta.
Waterborne diseases, disruption of livelihoods, and reduced access to clean water are major concerns identified in the study.
The study highlights the importance of community‐based adaptation strategies to mitigate the impact of flooding and pollution.
