Abstract Direct seawater electrolysis at industrially relevant current densities is constrained by chloride adsorption, competing chlorine oxidation, and accelerated anode corrosion. Here, we identify interfacial stannate formed during anodic operation as a key species responsible for suppressing Cl– adsorption and competing chlorine evolution. Operando Raman spectroscopy, inductively coupled plasma mass spectrometry, and time-of-flight secondary ion mass spectrometry reveal the partial dissolution of incorporated Sn species and the enrichment of stannate at the reconstructed catalyst–electrolyte interface, while density functional theory calculations further support its role in weakening Cl– adsorption. The resulting Sn-containing NiFe anode requires an overpotential of 377 mV to reach 1 A cm–2 and sustains operation at 1 and 2 A cm–2 for 1500 and 850 h, respectively. An anion-exchange-membrane electrolyzer further delivers 1 and 4 A cm–2 at cell voltages of 1.90 and 2.54 V at 80 °C, operates continuously for 1000 h at 1 A cm–2, and withstands 4500 start–shutdown cycles over 250 h. These results establish a direct link between working-state stannate chemistry and long-term chloride resistance under ampere-level seawater electrolysis.

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.

Thermal energy, encompassing both heating and cooling demands, accounts for the largest share of global energy consumption. Harvesting thermal energy from the environment, including the Sun and darkness, holds promise for decarbonizing thermal sectors, but suffers from low efficiency and intermittency. Here, inspired by ginkgo leaves featuring wax-coated vertical palisade cells, a 24-h bidirectional thermal energy harvesting approach is developed by integrating spectrally selective aerogels with anisotropic composite phase change materials (CPCMs). During daytime, sunlight is captured, converted into heat, and stored in anisotropic CPCMs with high axial thermal conductivity (24.16 W·m −1 ·K −1 ) and an anisotropy ratio of 3.7. Under one-sun irradiation, a high solar thermal energy storage efficiency of 87.5% with a peak temperature of 382.3 K is achieved by leveraging spectrally selective aerogels exhibiting “greenhouse effects”. At night, a maximum radiative cooling power of 118.8 W·m −2 is attained, enabling cold energy storage at a temperature 4.0 K below ambient. The proposed leaf-inspired device operates continuously over 24 h, delivering annual thermal energy savings of 5321.4 MJ·m −2 ·yr −1 , outperforming standalone solar thermal and radiative cooling systems by 44.8% and 223.3%, respectively. This bioinspired bidirectional energy harvesting strategy employing both solar and outer space resources, establishes a promising approach toward a carbon-neutral thermal energy supply.

Site-selectively chemical bioconjugation of peptides and proteins can improve the therapeutic exploration of modified protein drugs. Only 3.8% natural abundance of phenylalanine in protein and nearly 90% of proteins contain at least one phenylalanine residue in their sequenced, showing the potential in biopharmaceutical utility of the phenylalanine bioconjugation. However, the covalent bioconjugation of native phenylalanine is one of the most challenging problems in protein modification. Herein, an approach to protein modification is described that relies on a photoredox method for the site-selective bioconjugation of phenylalanine. This methodology has been validated on peptides as well as protein insulin using a straightforward and mild condition. In addition, based on characterization by near-UV CD spectroscopy and small angle X-ray scattering (SAXS), this pyrazole labeling approach permitted the insulin hexamer to completely dissociate into the monomeric form, thus making it a potential candidate for use as rapid-acting insulin for the treatment of diabetes.

The diffusion of generated H + ions in glucose sensing process is critical for the sensitivity of sensor. Although many glucose sensors assembled by two dimensional (2D) materials (MXene, graphene, MoS 2 et al.) have been extensively studied, the detailed analyses about the diffusion of H + ions are still rarely reported. Herein, hybrid Ti 3 C 2 -rGO film is fabricated by electrostatic self-assembly utilizing the 2D Ti 3 C 2 and graphene sheets to focus on the H + ion’s diffusion dynamic properties related to the sensing performance. Through controlling the graphene content, this hybrid Ti 3 C 2 -rGO film provide the effective H + ion diffusion channels. Based on the comprehensive analyses of cyclic voltammogram (CV) and electrochemical impedance spectroscopy (EIS), the corresponding localized conduction and enzymatic reaction at interfaces between the Ti 3 C 2 -rGO electrodes and glucose solution were investigated. According to the Warburg impedance in Nyquist plot from EIS, it is certified that the H + ion diffusion in low frequency range may play a significant role in the sensing mechanism of the glucose sensor. Moreover, the relationship derived from the interaction including interlayer spacing, H + ion diffusion and the sensing performance further reveal the H + ion diffusion as the dominant origin of the enhanced glucose sensitivity. This analysis will provide fundamental insight into the electrode structures assembled with 2D materials to optimize the sensor design in terms of ion transport dynamics.

Photocatalytic water splitting for hydrogen evolution (PHE) is an effective and sustainable strategy to alleviate energy shortages and environmental issues. However, active hydrogen (H*), as a critical intermediate, has low generation and desorption rates that limit the development of PHE. Herein, a ZnCdS/MoO 3-x heterojunction is prepared by a two-step solvothermal method and applied to a photocatalytic hydrogen evolution reaction under visible light conditions. The band structure and electron spin resonance (ESR) confirm the formation of an S-scheme heterojunction in ZnCdS/MoO 3-x , promoting the utilization of photo-generated carriers and thereby enhancing H* generation on ZnCdS. Furthermore, in-situ ESR, quasi in-situ Raman spectroscopy and in-situ DRFTIRS spectroscopy demonstrate that the H* is subsequently transferred from ZnCdS to MoO 3-x via the hydrogen spillover effect. The H* is then confined within the lattice of MoO 3-x and forms H x MoO 3-x in situ. Finally, the electrochemical tests and DFT calculations demonstrate that the H x MoO 3-x acts as a “hydrogen pump”, lowering the H* desorption barriers and ultimately enhancing the hydrogen evolution of the system. Therefore, the optimum hydrogen evolution rate of ZnCdS/MoO 3-x reaches 7.9 mmol·g −1 ·h −1 , which is 26.3 times higher than that of pure ZnCdS, along with a hydrogen storage capacity of 0.36 wt%. This work offers a novel approach for achieving efficient and sustained PHE reactions by modulating the generation and desorption rates of the intermediate H*.

The lithium-ion sieve primarily exists in powder form, which poses challenges such as poor fluidity and permeability, as well as difficulties in recovery. The H₂TiO₃ (HTO) particles were introduced into polyacrylamide (PAM) via in situ polymerization to prepare a tough and porous nanocomposite hydrogel (HTO@PAM). This method effectively addresses the recovery difficulties associated with powdered lithium-ion sieves and, due to the hydrophilic groups in polyacrylamide, enhances the desorption of Li + and improves the adsorption performance. The results show that HTO@PAM-4 is the optimal ratio, with an adsorption performance of 32.8 mg/g. Tensile strength tests using a universal testing machine indicated that HTO@PAM-4 has a tensile strength of 0.19 MPa, demonstrating excellent mechanical properties. Infrared spectroscopy detected the presence of hydrophilic groups (-CONH 2 ) in HTO@PAM, and surface tension measurements showed a water contact angle of 8.9 °, indicating good hydrophilicity. The recyclability of HTO@PAM-4 was investigated, and after six cycles, the adsorption capacity was 25.4 mg/g, which is 77 % of the maximum adsorption performance, demonstrating recyclability. The results indicate that HTO@PAM exhibits excellent mechanical properties, adsorption performance, and recyclability, making it a material with promising practical applications.

The immobilisation mechanism of Pu(IV) by Portland cement-based material is not well understood. This study aims to reveal the immobilisation mechanism and occurrence status of Ce(IV) (chemical analogue of Pu(IV)) in Portland cement paste. The addition of Ce(NO 3 ) 4 first slightly retarded then accelerated the early-age hydration of Portland cement , thereby resulting in an increase of compressive strength by 29 %. The main contributor to immobilisation of Ce is Portland cement rather than zeolite . The hydration products were not altered by Ce(NO 3 ) 4 addition, whereas the hydration degree and mean chain length of C-(Al/Ce)-S-H increased. Over 99.99 % of Ce was immobilised by synthesised C-S-H. A analysis of the synthesised C-S-H confirmed the formation of C-Ce-S-H, where Ce tetrahedra took the bridging site of silicate chain of C-Ce-S-H. Nano-crystalline CeO 2 grains were identified, which intermixed with C-Ce-S-H. Approximately 90 % of Ce were immobilised by C-Ce-S-H, and the rest exist as nano-crystalline CeO 2 grains.

An efficient one-pot synthesis of 1,1′-biisoquinolines by a three-component reaction of commercially available raw materials (benzils, NH4OAc, and alkynes) is disclosed. This complicated reaction involves in situ diimine formation via benzil-NH4OAc condensation, Rh(III)-catalyzed 2-fold imine-directed C–H activation, and annulation with alkynes. Both symmetric and unsymmetric 1,1′-biisoquinolines could be assembled in moderate to high yields. The reaction mechanism is supported through ESI-MS, in which Cp*ClRh+, Cp*(OAc)Rh+, Cp*(OPiv)Rh+, and two rhodacycle intermediates are successfully detected to explain the evolution of rhodium species.

Nanoimmunotherapy, the application of nanotechnology for sustained and targeted delivery of antigens to dendritic cells (DCs), has attracted much attention in stimulating antigen-specific immune response for antitumor therapy. In order to in situ deliver antigens to DCs for efficient antigen presentation and subsequent induction of strong cytotoxic T lymphocytes (CTL) response, here we developed a multi-peptide (TRP2 180–188 and HGP100 25–33 ) and toll-like receptor 4 agonist (monophosphoryl lipid A) codelivery system based on lipid-coated zinc phosphate hybrid nanoparticles (LZnP NPs). This delivery system equips with the chelating property of zinc to realize the high encapsulation efficiency with antigenic peptides and the influence on immune system with adjuvant-like feature. The combination of H-2K b and H-2D b -restricted peptides could provide multiple epitopes as the target of specific MHC alleles, making tumor more difficult to escape from the surveillance of immune system. The formulated LZnP nano-vaccine with the size of 30 nm and outer leaflet lipid exhibited antitumor immunity as the secretion of cytokines in vitro and increased CD8 + T cell response from IFN-γ ELISPOT analysis ex vivo . The antitumor effects were further evidenced from the prophylactic, therapeutic and metastatic melanoma tumor models compared with free antigens and single peptide-loaded nano-vaccines. These results validate the benefit of LZnP-based vaccine for antitumor immunity and indicate that co-delivery of tumor antigens along with adjuvant may be an optimized strategy for tumor immunotherapy .

Silicon (Si)-based materials have been identified as next-generation preferred anode materials owing to their ultra-high specific capacity, environmental friendliness and low price. However, the defects in Si-based materials ( e.g., the large volume change with unstable solid electrolyte interface during repeated lithiation/delithiation processes and low intrinsic conductivity), will significantly destroy the integrity of electrode structure and get slow dynamic performance, resulting in a fast capacity fading. Herein, we prepared various silicon‑aluminum‑copper dendrites (named SCD-1/2/3) via a two-step displacement dealloying process, which was devoted to simultaneously improving structural instability, low ionic/electronic conductivity of Si crystals. Therefore, the SCD-2 anode possessed an initial Coulombic efficiency of 80 % and exhibited a superior capacity of 1851.7 mA h g −1 at 1 A g −1 after 100 cycles. This paper provides a simple method to gain the Si anodes with high initial Coulombic efficiency, relieved volume expansion and long cycling life.

Aqueous zinc-ion batteries (AZIBs) have recently been paid great attention due to their robust safety features, high theoretical capacity, and eco-friendliness, yet their practical application is hindered by the serious dendrite formation and side reactions of Zn metal anode during cycling. Herein, a low-cost small molecule, nicotinamide (NIC), is proposed as an electrolyte additive to effectively regulate the Zn interface, achieving a highly reversible and stable zinc anode without dendrites. NIC molecules not only modify the Zn 2+ solvation structure but also preferentially adsorb on the Zn surface than solvated H 2 O to protect the Zn anode and provide numerous nucleation sites for Zn 2+ to homogenize Zn deposition. Consequently, the addition of 1 wt% NIC enables Zn||Zn symmetric cells an ultra-long lifespan of over 9700 h at 1 mA cm −2 , which expands nearly 808 times compared to that without NIC. The advantages of NIC additives are further demonstrated in NaVO||Zn full cells, which exhibit exceptional capacity retention of 90.3 % after 1000 cycles with a high Coulombic efficiency of 99.9 % at 1 A/g, while the cell operates for only 42 cycles without NIC additive. This strategy presents a promising approach to solving the anode problem, fostering advancements in practical AZIBs.
