Protein self-assembly has attracted extensive interest in the field of biomaterials and biomedicine due to its inherent biocompatibility and flexible designability. In this paper, we propose a potential route to generate a photoelectrochemical (PEC) sensing platform through Sn-triggered protein self-assembly. Specifically, Sn2+ ion was used to trigger the self-assembly of bovine serum albumin (BSA) to form in situ Sn/BSA film on the indium tin oxide (ITO) glass. Then, a CdS thin film as a PEC active material was electrodeposited on the Sn/BSA modified ITO electrode. The hybrid Sn/BSA film was demonstrated to stabilize the PEC response of the CdS. A dual-electrode PEC cell comprised a graphene oxide (GO)-modified photocathode and a Sn/BSA hybrid film/CdS-loaded photoanode. Pb2+-response deoxyribozymes (DNAzymes) were hybridized with the substrate strands tagged with Au nanoparticles (Au NPs) and then immobilized on the photocathode. Upon Pb2+-induced cleavage, Au NP-linked oligonucleotide fragment dislocated from the photocathode surface, resulting in a decrease in the PEC response. The present PEC biosensor showed highly sensitive detection of Pb2+ with a wide detection range from 10.0 fM to 0.1 μM and a low detection limit of 4.0 fM. This work demonstrates that the Sn/BSA hybrid film has potential application prospects in PEC sensing, thereby providing a new way of thinking for the design and development of the bioinspired biosensor.

Triacylglycerols (TAG) are differences in fatty acid distributions between infant formula and human milk. In this study, fish oil (Tilapia, Golden pompano, Tiger grouper, and Basa) showed the potential as the source of human milk fat substitutes by comparing TAG profiles with infant formula and human milk. The total lipids and TAG of fish were concentrated in the by-products of fish (head and viscera) and contained high levels of palmitic acid, oleic acid, and linoleic acid. Compared with infant formula, fish oil was closer to human milk in sn -2 fatty acid distribution, and sn -2 palmitic acid level in fish oil exceeded 52 % of total palmitic acid, Golden pompano head was the highest (64.46 %). Further research showed that the content of sn -2 palmitoyl TAG (OPO and OPL dominated) increased from 157.16 mg/g TAG to 305.18 mg/g TAG by isopropanol enrichment (solid–liquid ratio: 1:4, temperature: −12 °C, time: 4 h).

The anode corrosion induced by the harsh acidic and oxidative environment greatly restricts the lifespan of catalysts. Here, we propose an antioxidation strategy to mitigate Ir dissolution by triggering strong electronic interaction via elaborately constructing a heterostructured Ir-Sn pair-site catalyst. The formation of Ir-Sn dual-site at the heterointerface and the resulting strong electronic interactions considerably reduce d-band holes of Ir species during both the synthesis and the oxygen evolution reaction processes and suppress their overoxidation, enabling the catalyst with substantially boosted corrosion resistance. Consequently, the optimized catalyst exhibits a high mass activity of 4.4 A mgIr−1 at an overpotential of 320 mV and outstanding long-term stability. A proton-exchange-membrane water electrolyzer using this catalyst delivers a current density of 2 A cm−2 at 1.711 V and low degradation in an accelerated aging test. Theoretical calculations unravel that the oxygen radicals induced by the π* interaction between Ir 5d-O 2p might be responsible for the boosted activity and durability.

Electrochemical desalination offers a promising route to address water scarcity, but current methods often face limitations in salt removal rate and capacity. This study introduces an ultrafast electrocatalytic desalination system that leverages the electrochemical reduction of CO 2 to formate (CO 2 RR) to drive efficient salt removal. The optimized bimetallic Sn/Cu-based polyphthalocyanine (Sn 2 Cu 1 PPc) exhibits exceptional CO 2 RR performance, achieving a peak FE formate of 90.3 % at −1.0 V vs. RHE and a j formate of 84.8 mA cm −2 . In-situ spectroscopic analysis and density functional theory (DFT) calculations reveal that the incorporation of Cu-N 4 units into the Sn-based polyphthalocyanine (SnPPc) promotes CO 2 adsorption and facilitates active hydrogen provision, leading to the observed enhancement in CO 2 RR activity. Using the Sn 2 Cu 1 PPc catalyst, our system achieves a salt removal rate of 1701.3 μg cm −2 min −1 and a formate production rate of 0.79 mmol h −1 cm −2 when treating natural seawater, resulting in potable water with 99.06 % salt removal efficiency. This performance is enabled by a high current density (∼70 mA cm −2 ) during CO 2 RR, which significantly enhances ion transport across the membranes, making this one of the most effective desalination approaches reported. This work demonstrates the potential of coupling CO 2 RR with desalination for sustainable water production and CO 2 mitigation, while also advancing the design of efficient Sn-based electrocatalysts for formate production.

Finding sodium solid electrolytes (SSEs) with good performance is key to building all-solid-state sodium batteries. In the development of solid electrolytes, halogen doping has been shown to be an effective approach. However, it has rarely been applied to chalcogenide-based SSEs, possibly because of strict structure constraints. In this work, the strategy of halogen doping is successfully demonstrated on Na3.67[Sn0.67Si0.33]0.67P0.33S4, a novel SSE with high structural tolerance. The halogen-doped samples formulated as Na3.57[Sn0.67Si0.33]0.67P0.33S3.9X0.1 (X = Cl, Br, and I) exhibit higher ionic conductivities and lower activation energies than the pristine sample. Na3.57[Sn0.67Si0.33]0.67P0.33S3.9I0.1, the I-doped sample, has the highest ambient ionic conductivity of 1.08 mS cm–1 and the lowest activation energy of 0.24 eV. Structure analysis indicates that the high electronegativity of Cl atoms plays an important role in improving the conduction of Na+ ions in Cl-doped samples. The large atomic radius and high polarizability of I are more important factors to accelerate the transportation of Na+ ions in the I-doped counterpart. Furthermore, the all-solid-state sodium batteries assembled with Na3.57[Sn0.67Si0.33]0.67P0.33S3.9I0.1 as solid electrolytes show decent cyclic stability at 30 °C with a current density of 0.15 A g–1. This work systematically manifests the effect of halogen doping in SSEs, providing a versatile method to develop novel SSEs.

With the unprecedented rise of flexible electronic technology, it is imperative to develop the matched flexible power supply systems. Magnesium ion battery (MIB), as a promising next-generation battery system, shows significant potential as a power source for flexible electronic devices. However, the research on flexible MIB remains in its infancy, and the exploration of novel and reliable flexible electrodes is crucial. Herein, a binder-free and flexible self-supporting electrode with bimetallic Bi–Sn nanoparticles anchored in carbon nanofiber (CNF@Bi-Sn) was fabricated via electrospinning method combined with subsequent calcinations, and applied to MIBs for the first time. The CNF@Bi-Sn simultaneously integrated the advantages of hierarchical porous carbon nanofiber framework, the homodisperse nanosized Bi-Sn particles, and the increased phase/grain boundaries, which were beneficial for improving the structural stability and facilitating Mg 2+ diffusion kinetics. The CNF@Bi-Sn alloy anode demonstrated impressive performance with high initial specific capacity of 738mAh/g, exceptional rate capability and outstanding cycling stability of 150mAh/g at 40 mA g −1 after 100 cycles. Significantly, the quantitative kinetic analysis, ex-situ SEM, TEM and XRD were conducted to reveal the structural evolution during cycling and the magnesium storage mechanism based on reversible two-phase alloying/de-alloying transformation reactions. Furthermore, the full batteries were assembled, demonstrating its potential for practical applications. This protocol sheds light on exploring high-performance flexible self-supporting alloy anode for future flexible power systems.

Electro-catalytic technology is a promising approach for wastewater treatment, owing to its easy operation, minimal generation of secondary pollution, small foot-print and rapid start-up. In this work, the chlorine evolution potential of the Pd-Sn modified ruthenium(Ru)-iridium(Ir) electrode was investigated for the electro-catalytic treatment of high chlorine ammonia-nitrogen wastewater. The effect of reaction conditions on the removal of ammonia-nitrogen, kinetics and apparent activation energy of ammonia-nitrogen removal were studied. The possible denitrification process of high chlorine ammonia-nitrogen wastewater was discussed. The results indicated that the chlorine evolution potential of the Pd-Sn modified Ru-Ir electrode was 1.0956 V(vs. SCE). The electro-catalytic treatment of high chlorine ammonia-nitrogen conformed to zero-order kinetic law, and the apparent activation energy of removal process was 14.089 kJ/mol. With a current was 0.5 A, the removal efficiency of ammonia-nitrogen could achieve 100% at a reaction time of 40 min. Indirect oxidation played an essential role in the electro-catalytic ammonia-nitrogen removal using the Pd-Sn modified Ru-Ir electrode. This paper demonstrated that the electro-catalytic technology was a promising approach for efficiently treating the high chlorine ammonia-nitrogen wastewater.

Coaxial core-shell hierarchical flower-like cobalt oxide@doped-Sn carbon nanofiber (Co3O4@Sn-CNF) prepared by loading Co3O4 shells on Sn-CNF that were synthesized via electrostatic spinning and subsequently thermally treated by electrophoretic deposition were used as the anode material for lithium- ion batteries in this paper. The Co3O4 shells were not solid but flower-like, provided abundant inner space, facilitated the transfer of lithium ions and electrons and the contact with the electrolyte via the increase in space, increased the electrochemical reaction sites, and improved the electrochemical performance. After the initial discharge specific capacity of 1519 mAh g -1 , the discharge specific capacity of the Co3O4@Sn-CNF reached 1000 mAh g -1 without an obvious capacity decay, and the coulombic efficiency reached 98.6%, indicating the excellent cycle stability of this material. In addition, a specific capacity recovery of 90% demonstrated a remarkable rate performance. The improvement in the electrochemical performance was due to the introduction of the Sn-CNF, which had a good electroconductivity and mitigated the volume deformation due to the elastic deformation of the CNF, in addition to the unique and firm structure.

Our study offers a novel sn -1,3 specific lipase MAJ1 from marine member Janibacter sp. strain HTCC2649 for preparing long-medium-long (LML) type structured triacylglycerols (TAGs). Firstly, the resin ECR1030 was selected as a suitable support for the immobilization of lipase MAJ1. An efficient synthesis of LML-type structured TAGs by the immobilized lipase MAJ1-catalyzed interesterification of methyl palmitate and tricaprylin was studied in a solvent-free system. The reaction conditions, including substrate molar ratio, temperature and enzyme loading, were optimized. Under the optimum conditions (immobilized lipase MAJ1 of 45 U/g, substrate molar ratio of 4:1, temperature of 35 °C, reaction time of 24 h), the structured TAGs with double long chains (DLCST) were obtained in a yield of 44.3 mol%. Secondly, multi-dimensional mass spectrometry-based shotgun lipidomics (MDMS-SL) was employed to quantify each TAG positional isomer in DLCST. The content of 1,3-dipalmitoyl-2-capryloyl- sn -glycerol in DLCST was 97.6% determined by the MDMS-SL technology.

Solar-driven water evaporation is a promising solution to water pollution, the energy crisis, and water shortages. However, the approach in which the photothermal film is in direct contact with bulk water for water evaporation may lead to a large amount of heat loss, thereby reducing the light-to-heat conversion efficiency (η) of the photothermal film. Here, a highly efficient solar-driven water evaporation system was developed using a Co–Sn alloy-deposited Teflon (PTFE) film (Co–Sn alloy@PTFE) and super-absorbent polymers (SAPs) supported with a floating foam substrate. The Co–Sn alloy with full-spectrum (200–2500 nm) absorption characteristics is devoted to high light-to-heat conversion, while the porous PTFE with high mechanical performance can support the Co–Sn alloy. We used density functional theory to prove that the Co–Sn alloy had a strong adhesive force with PTFE without surfactants due to the high adsorption energy between the (101) crystal plane of the Co–Sn alloy and the hydroxyl group on the PTFE film. Importantly, via the SAP-based “water pump” design, we improved the η of the Co–Sn alloy@PTFE film to 89%, mainly because the SAP not only effectively performed water transportation but also markedly reduced the heat loss of the Co–Sn alloy@PTFE film. Our work highlights the strong potential of Co–Sn alloy@PTFE-based light-to-heat conversion systems for realizing highly effective solar energy-driven water evaporation.

The development of insertion-type anodes is the key to designing “rocking chair” zinc-ion batteries. However, there is rare report on high mass loading anode with high performances. Here, {001}-oriented BiOCl nanosheets with Sn doping are proposed as a promising insertion-type anode. The designs of cross-linked CNTs conductive network, {001}-oriented nanosheet , and Sn doping significantly enhance ion/electron transport, proved via experimental tests and theoretical calculations (density of states and diffusion barrier). The H + /Zn 2+ synergistic co-insertion mechanism is proved via ex situ XRD, Raman, XPS, and SEM tests. Accordingly, this optimized electrode delivers a high reversible capacity of 194 mA h g −1 at 0.1 A g −1 with a voltage of ≈0.37 V and an impressive cyclability with 128 mA h g −1 over 2500 cycles at 1 A g −1 . It also shows satisfactory performances at an ultrahigh mass loading of 10 mg cm −2 . Moreover, the Sn-BiOCl//MnO 2 full cell displays a reversible capacity of 85 mA h g −1 at 0.2 A g −1 during cyclic test.
