The development of aqueous zinc-ion batteries is crucial for advancing sustainable energy storage technologies. However, their widespread application is hindered by Zn corrosion and uncontrolled Zn dendrite growth. One promising approach involves creating a functional organic-inorganic interface on the Zn surface. Traditional binders, such as polyvinylidene fluoride (PVDF), fail to regulate water activity and ion migration, limiting the effectiveness of the interface. Herein, we introduce an aqueous dual ionic/electronic conducting binder, poly(3,4-ethylenedioxythiophene): polystyrene sulfonate (PEDOT:PSS), to build a water-scarce, Zn 2+ -enriched interface. Our findings demonstrate that PEDOT:PSS not only facilitates uniform distribution of inorganic fillers, forming a cohesive and compact interface, but also significantly enhances mechanical integrity. Additionally, the sulfonate groups within the binder matrix disrupt the hydrogen bond network of water molecules, reducing water activity and lowering the desolvation energy barrier of Zn(H 2 O) 6 2+ clusters. Therefore, the transference number of Zn 2+ is elevated to 0.81 (compared to 0.61 with PVDF), mitigating undesirable side reactions and enabling dendrite-less Zn deposition. Consequently, symmetrical Zn||Zn cells with PEDOT:PSS binder demonstrate a lifetime with 4.2 times longer than those with PVDF. This work underscores the critical role of binder chemistry in stabilizing metal anodes for aqueous batteries.

The abiotic interaction between ferric phosphate and major macromolecular organics (protein, saccharide, humic substance) in waste activated sludge (WAS) were studied, and the effect of phosphate on protein and the reaction mechanism were discussed in particular. With the addition of ferric phosphate, the concentration of protein was greatly reduced with a removal efficiency of 77.3%, accompanied by a remarkable increment of NH 4 + -N concentration (13.5 mg/L) when the release efficiency of NH 4 + -N reached 52.7%, while fulvic acid (FA) and glucose barely changed. PO 4 3 ‐ was the functional ion dominating the protein decomposition and NH 4 + -N release. The maximal release efficiency of NH 4 + -N (66.9%) occurred at pH 7, and the NH 4 + -N concentration mainly depended on the protein concentration, while the presence of FA and glucose would interfere the decomposition of protein. The analytical results of circular dichroism (CD) suggested that the reaction went through two stages: firstly, the process was relatively stable and phosphate showed a tendency to facilitate the transition from helices to β-sheets; then peptide chains on the helices were broken and deamination of amino acid residues occurred. Due to the loss of hydrophilic groups, hydrophobicity of the residue was further enhanced, resulting in its co-precipitation with protein. The results are applicable to proteins with similar structures to bovine serum albumin (BSA). This study provides a novel insight into the transformation of organic matters and phosphorus (P) in the anaerobic treatments of WAS.

Antibiotics significantly impact the anaerobic fermentation of waste activated sludge (WAS). However, only a few studies have been conducted on the influence of ofloxacin (OFL) on the production of short-chain fatty acids (SCFAs) and its underlying mechanisms during WAS anaerobic fermentation. This study aimed to elucidate the impact of OFL on SCFA production from alkaline-pretreated WAS fermentation. The results showed that the addition of 10 mg OFL/kg SS led to a peak concentration of 2931.85 mg COD/L, resulting in a 1.1-fold increase in SCFA production compared to the control group. Further exploration revealed that OFL simultaneously promoted WAS solubilization, hydrolysis and acidification. Additionally, a low concentration of OFL increased the abundance of hydrolytic acidifying bacteria but decreased the abundance of SCFA-consuming bacteria. Metagenomic analysis revealed an enhanced abundance (103.76–134.56%) of critical genes related to extracellular hydrolysis (i.e., malZ , bglX , and degP ), membrane transport (i.e., msmX , gtsA , and gltI ), substrate metabolism (i.e., glk , glnA , and gdhA ), and SCFAs biosynthesis (i.e., ackA and fabG ) in the presence of low OFL concentration. These findings broadened our understanding regarding the influence exerted by OFL on WAS anaerobic fermentation.

Medium chain fatty acids (MCFAs) production from waste activated sludge (WAS) is restricted by poor biodegradability of WAS and low electron transfer efficiency. Herein, a novel ferroferric oxide (Fe 3 O 4 ) technique was proposed. Results indicated that the MCFAs yield and selectivity were respectively enhanced by 155.4% and 66.7% in the Fe 3 O 4 -mediated WAS. Mechanistic studies disclosed that Fe 3 O 4 promoted substrates degradation through conducting dissimilatory iron reduction (DIR) and stimulating hydrolase activity, providing precursors for chain elongation (CE). Generally, Fe 3 O 4 improved the key processes for MCFA production at different degrees, i.e., hydrolysis, acidification and CE. Interestingly, MCFAs yield enhancement was primarily ascribed to facilitated electron transfer rather than DIR or produced ferrous iron, which could be supported by the analyses of electrochemical properties, electron transfer system activity and morphology. Further, Fe 3 O 4 shifted the key microorganisms in favor of MCFAs production. Overall, this strategy could improve MCFAs production, sludge dewatering and phosphorus removal, concurrently.

Aqueous zinc metal batteries are ideal candidates for grid storage applications. However, their practical application is hindered by a narrow operating temperature range and a limited electrolyte electrochemical stability window, both of which can be attributed to the water activity. Here, to minimize water activity in the electrolyte solution, we introduce a nanoengineered approach in which the water molecules are confined within a hydrophilic–hydrophobic water solvation sheath. The hydrogen-bond interaction with the hydrophilic groups in the inner solvation layer effectively suppresses water decomposition, and the hydrophobic solvents in the outer solvation layer establish a repulsive effect against water molecules. As a proof of concept, a hydrophobic and non-polar hydrofluoroether cosolvent is introduced into a Zn-ion aqueous electrolyte solution and tested together with various fluorinated hydrotrope molecules to favour the compatibility of the cosolvent with water. By such a water confinement strategy, an average Zn plating/stripping reversibility of 99.92% is achieved for over 4,000 cycles at 2.0 mA cm −2 and 2.0 mAh cm −2 in a Zn||Cu coin cell configuration. When tested in a Zn||VOPO 4 ·2H 2 O lab-scale cell configuration, the selected aqueous-hydrotrope hybrid electrolyte solution enables long-lasting and highly reversible battery performance across temperatures from −80 °C to +60 °C.

Hydrogen evolution reaction and Zn dendrite growth, originating from high water activity and the adverse competition between the electrochemical kinetics and mass transfer, are the main constraints for the commercial applications of the aqueous zinc-based batteries. Herein, a weak H-bond interface with a suspension electrolyte is developed by adding TiO2 nanoparticles into the electrolytes. Owing to the strong polarity of Ti–O bonds in TiO2, abundant hydroxyl functional groups are formed between the TiO2[110] active surface and aqueous environment, which can produce a weak H-bond interface by disrupting the initial H-bond networks between the water molecules, thereby accelerating the mass transfer of Zn2+ and reducing the water activity. In consequence, the Zn||Zn symmetrical cells display reversible Zn plating/stripping behaviors with a high Coulombic efficiency of 99.7% over 700 cycles. Moreover, the TiO2-based suspension strategy is also applicable to other zinc salt systems and exhibits fast plating/stripping behaviors. The suspension electrolyte enables long-term full cells, including Zn||PANI hybrid capacitors and Zn||ZnVO full batteries.

The employment of aqueous zinc salt solutions as electrolytes confers cost and safety advantages to aqueous zinc-ion capacitors (ZICs). However, the high chemical H 2 O with low boiling point in typical aqueous zinc sulfate (ZS) electrolyte greatly restricts the performance of ZICs in high-temperature conditions. Herein, a ternary deep eutectic solvent (DES) electrolyte capable of withstanding extreme high temperatures of up to 80 °C is synthesized for the first time by utilizing inter-component hydrogen bonding. The DES with optimized component ratios allows long-term stable cycling of Zn||Zn cells for >1200 h with nearly 100 % Coulombic efficiency. When used as the high-temperature electrolyte, ZICs at 80 °C yield a much higher specific capacitance of up to 247 F g −1 than at room temperature, while those with ZS as the electrolyte hardly work properly under this condition. The hydrogen bonding system reconfigured by ligand competition in DESs effectively inhibits Zn dendrite formation and the activity of H 2 O, thus endowing ZICs up to 10000 cycles at 80 °C. This ternary DES not only opens the way for the design of high-temperature electrolytes for ZICs, but also offers new possibilities for the development of other energy storage devices that need to be adapted to extreme operating environments.

Aqueous zinc-ion batteries (AZIBs) are promising candidates for next-generation energy storage due to their intrinsic safety and environmental compatibility. However, parasitic reactions induced by active water molecules in conventional aqueous electrolytes severely degrade electrochemical performance and cycling stability. Herein, a stretchable, adhesive, anti-freezing hydrogel electrolyte with dual-functional water regulation is synthesized via a one-pot radical polymerization strategy, where acetate (Ac − ) anions and hydrophilic amide (─CONH 2 ) groups on polyacrylamide (PAM) chains synergistically regulate water activity. This design disrupts water's intrinsic hydrogen bond network and suppresses interfacial side reactions, enabling stable AZIBs operation across a wide temperature range (−20 to 100 °C). Consequently, Zn||Cu cells employing PAM-Zn(Ac) 2 -4KAc (denoted PAM-ZnK4Ac) hydrogel electrolyte achieve an average Coulombic efficiency of 99.7% over 500 cycles, demonstrating outstanding reversibility. Meanwhile, Zn||polyaniline (PANI) cells retain 81.4% capacity after 1100 cycles at −20 °C and operate effectively up to 100 °C. This work establishes a facile yet effective strategy for preparing hydrogel electrolytes, advancing all-climate AZIBs toward extreme-environment energy storage and flexible electronics.

Exogenous contaminants often co-occur in waste-activated sludge (WAS), but their potential mutual interactions and joint effects on the WAS treatment are less concerning. This work revealed that surfactants induced and aggravated the toxicity of Fe2O3 nanoparticles (NPs) in volatile fatty acids (VFAs)’ biosynthesis during WAS anaerobic fermentation. The VFA production exhibited a 40.1 and 20.3% inhibition compared to the individual LAS and CTAB reactors, respectively. A mechanistic exploration implied that the WAS solubilization, hydrolysis, and acidification steps during VFA generation were restrained. Moreover, the Fe2O3 NPs’ and surfactants’ coexistence suppressed the acid-forming bacteria (i.e., Saprospiraceae_uncultured, Bacteroidetes vadinHA17_norank) and the homologous metabolic functions responsible for substrate hydrolysis (e.g., malZ and pepD), intracellular metabolism (e.g., pfkA and gdhA), VFAs’ biosynthesis (e.g., bkdA and ackA), and ATP generation (e.g., atpE and atpH), resulting ultimately in VFAs’ reduction. Furthermore, the surfactants contributed to the dispersibility of coexisting Fe2O3 NPs to maintain the high reactivity of NPs. Besides, the WAS disintegration triggered by surfactants increased the interactions between Fe2O3 NPs and microorganisms, thereby aggravating toxicity. Our study provides novel insights into environmental behaviors of co-occurring contaminants in the anaerobic environment and provides in-depth guidance for practical WAS treatment.

The rich valence states (−2 to +6) make elemental Te become a high-capacity electrode in aqueous batteries. The conversion process (Te to TeO 2 ) generates soluble Te 4+ species in aqueous electrolyte. The suppression of conversion process enables a long-term Te electrode at the cost of a partial storage capacity. Herein, a polyethylene glycol additive is introduced to regulate the electrolyte environment. The low H 2 O activity hinders Te 4+ species formation and therefore leads to the insertion-type Te electrode. The reshaped NH 4 + solvation structure facilitates the fast H 2 O removal and firm PEG adsorption on the electrode surface, also improving water-induced side reactions. This, coupled with the introduction of carbon host, contributes to a high-stability Te electrode. Theoretical and experiment studies reveal the reshaped NH 4 + solvation structure/hydrogen-bond network, the strong adsorption capability of B-doped carbon, and the inhibited Te dissolution. Additionally, a series of in/ex-situ characterizations prove the intercalation-type mechanism and the enhanced cycling stability. As a result, this elaborate electrode delivers a high reversible capacities of 376 mA h g −1 at 0.05 A g −1 and a long-term cycling stability with 73.8 % capacity retention at 5 A g −1 after 4500 cycles. This work provides a reference for the storage mechanism regulation in aqueous battery.

The natural reactivity of Zn metal in aqueous environments leads to surface deterioration and uncontrolled dendrite growth, posing challenges in the advancement of Zn-ion batteries. In this research, we introduce an environmentally friendly and cost-effective electrolyte additive, ammonium oxalate (AO), to significantly extend the cycle life of Zn-ion batteries with minimal usage. Oxalate ions within AO actively participate in the solvation of hydrated Zn ions and attach to the Zn anode surface prior to H 2 O molecules, creating a robust solid-electrolyte interface (SEI) layer. This SEI layer serves a dual purpose: it inhibits further reactions with H 2 O and restricts the two-dimensional movement of Zn ions, promoting the preferential growth of the (0 0 2) crystal plane. Consequently, Zn||Zn cells exhibit an impressive lifespan surpassing 1800 h (at 1 mA cm −2 , 1 mAh cm −2 ), and Zn||Cu cells experience a tenfold increase in cycling life. Moreover, Zn||MnO 2 full cells, incorporating this low-cost and highly efficient inorganic additive, maintain an outstanding 80.84 % capacity retention after 1200 cycles at 1 A g −1 . This breakthrough with AO offers a promising avenue for the practical implementation of Zn-ion batteries, emphasizing their cost-effectiveness and environmental sustainability.

New approaches for the engineering of well-defined, pore modality, and multi-chemical functionality nanocomposites are crucial to generate the next generation of functional materials with recoverable and easy preparation properties. Here, a catalyst and heat free polymerization reaction is exploited and fabricated zwitterionic system around magnetic nanoparticles. N-aminoethyl piperazine propane sulfonate (AEPPS) and dopamine (DA) are introduced as the zwitterionic system, which provided abundant zwitterionic groups (NH 2 , SO 3 − , N + ) and strong adhesion and various oxidation state properties. And that, the zwitterionic engineering will assemble between AEPPS and DA whereby Schiff base formation or Michael type addition. Whereafter, a series of sophisticated array of microscopic, spectroscopic, and structure techniques verify the formation of highly crosslinking internal zwitterionic architectures, well-defined core–shell structure, and better porosity. The zwitterionic structure–function relationships and striking porous structure are explored in a multi-interaction adsorption assay. The adsorption capacity of the magnetic nanocomposites was 1065.8 mg/g. And that, the system exhibited with hydrophilic-hydrophobic activity towards glycoprotein and better performance to bioactive protein (Ig-G) isolation form human whole blood sample. The synergistic enhancement interaction in hydrophilic target enrichment, easy preparation, and soft substrate properties of the AEPPS-DA zwitterionic materials make them intriguing candidates for sustainable biomedical loading and chromatographic separation.
