Establishing robust atomic-level interfaces, particularly through the selective modulation of surface active sites within heterojunctions to achieve superior solar energy conversion, remains largely unexplored. Herein, sulfur vacancy sites (V S ) in ZnIn 2 S 4 (ZIS) are selected, driven by the interaction between unsaturated zinc sites and the nitrogen-rich sites of g-C 3 N 4 , forming a step-scheme (S-scheme) heterojunction. The defect-induced interfacial Zn–N–C bonds not only provide rapid channels at the atomic level, thereby lowering the energy barrier for charge transfer, but also selectively tune the highly active pyrrolic N site to enhance H 2 evolution. Furthermore, molecular dynamics simulations (MD) combined with density functional theory (DFT) calculations reveal that V S regulates the pyrrolic N sites within the heterojunction, leading to a reduction in the Gibbs free energy for hydrogen production. Kinetic analysis by carrier transport activation energy (CTAE) indicates that the charge transfer energy barrier is accelerated, decreasing from 211.20 eV for ZIS/CN-360 % to 155.71 eV for V S -ZIS/CN-360 %. Consequently, the designed catalyst significantly enhances the H 2 yield (27.94 mmol g −1 h −1 ) in the absence of platinum. This work emphasizes the importance of generating defect-induced interfacial atomic channels, as well as changes in the surface microenvironment, which underscore the significance of defect heterostructures in promoting the photocatalytic process.

The treatment of arsenite pollution in water has always been concerned. Oxidation of high toxic As(III) to relatively low toxic As(V) by efficient photocatalytic oxidation technology is a research hotspot. This paper is focused on the active photocatalyst of TiO 2 @Fe 3 O 4 composites synthesized by a simple hydrothermal method for the efficient photocatalytic oxidation of As(Ⅲ). The successful construction of Ti–O–Fe interface bonds between TiO 2 and Fe 3 O 4 significantly promoted the transfer efficiency of photo-generated carriers, and further rapidly improved the photocatalytic oxidation efficiency of As(Ⅲ). The application results showed that the constructed TiO 2 @Fe 3 O 4 photocatalyst with 0.10 g Fe 3 O 4 (TF-0.10) could complete the transformation from As(Ⅲ) (10,000 μg/L) to As(Ⅴ) within 4 min with a high oxidation ratio of 100% and maintained the good properties with unchanged crystal structure after five cycles. Furthermore, the photocatalytic properties of TiO 2 @Fe 3 O 4 composites were still stable under different pH values. Electron paramagnetic resonance (EPR) consequence displayed that the superoxide radical (‧O 2 — ) and hole (h + ) were the main intermediate product in the arsenic photocatalytic oxidation system, and hydroxyl radical (‧OH) had little effect on this oxidation system. The possible mechanism of As(Ⅲ) photocatalytic conversion was further explored based on the results of the data analysis. Furthermore, this work provides a potential new idea for the practicability of efficient photocatalytic arsenic oxidation.

Alloy-type materials have aroused wide concern as potential anodes for Na-ion batteries (NIBs) because of their high theoretical capacities and suitable Na-storage potentials. Fabricating composites with carbon matrixes is the most common strategy to solve their key issues of large volume expansion and sluggish reaction kinetics. However, it is still challenging to achieve strong interfacial interaction between alloy-type materials and carbon matrixes, thus largely improving the buffering effect of carbon matrixes on volume change. Herein, we have developed a SnSb-graphene (SnSb-G) hybrid anode with interfacial Sn/Sb–C bonding via a plasma-assisted mechanochemical method. The Sn/Sb–C bonding can enhance the interfacial interaction between SnSb and graphene, which inhibits the detachment of SnSb nanoparticles from graphene upon cycling and promotes the buffering effect of graphene. Meanwhile, the strong interfacial bonding of conductive graphene network to SnSb nanoparticles can greatly facilitate the Na+ storage/transfer along the SnSb/graphene interface, rendering electrode superior performance at high rates. Therefore, as an anode for NIBs, the SnSb-G composite exhibits superb rate capability (301.5 mAh g–1 at 10.0 A g–1) and cyclic stability (85.8%/89.1% capacity retentions at 1.0/2.0 A g–1 after 1000 cycles). Moreover, the assembled full cell delivers a high energy density of 145 Wh kg–1 and superior cycling performance of 333.6 mAh g–1 after 200 cycles, demonstrating its potential for practical application. This work provides new insight to achieve high-performance alloy-type anodes for practical NIBs.

Achieving atomic-level surface integrity while maintaining a high material removal rate (MRR) remains a fundamental challenge in the polishing of fused silica due to its high hardness and brittleness. This study establishes a novel mechanistic framework for understanding how pH-driven interfacial bond dynamics govern chemo-mechanical polishing processes. By integrating multiscale experimental characterization (XPS, FTIR, Raman spectroscopy) with ReaxFF molecular dynamics simulations, we demonstrate for the first time that the dynamic equilibrium between the formation and rupture of Ce–O–Si interfacial bonds directly control removal efficiency and surface quality. Alkaline conditions enhance OH – activity, facilitating Si–O bond hydrolysis and stable Ce–O–Si linkage formation, resulting in the highest MRR (397.6 nm/min). Acidic environments promote citrate-mediated Ce 3 + complexation and nanocluster dispersion, enabling a rolling mechanism that achieves ultra-smooth surfaces (Sq = 0.086 nm). In contrast, neutral pH conditions suffer from PEG adsorption blocking active sites, leading to a 62 % reduction in MRR relative to alkaline systems. A 12.2-fold increase in MRR compared to SiO 2 abrasives (32.67 nm/min) confirms that chemical interfacial dynamics, rather than mechanical abrasion alone, are critical to material removal. This fundamental advancement provides a broadly generalizable theoretical basis for designing efficient, low-damage precision polishing processes across oxide-based optical materials and beyond.

Engineering interfacial properties of metal-sulfides toward excellent electrochemical capability is imperative for advanced energy-storage materials. However, they still suffer from an unclear mechanism of capacity fading, along with ineffective physical–chemical evolution. Herein, a highly-effective Sb 2 S 3 with double carbon is designed with interfacial Sb C bonds and double carbon, which boosts promoting of ion transferring and alleviates the separation of both active phases (Sb, S). Through “voltage-cutting” manners, the key elements of capacity improvement about phase transitions are further determined. As expected, even at 5.0 A g −1 , the lithium-storage capacity remains about 674 mAh g −1 . Utilized as sodium ion battery (SIB) anode, the rate capacity still reaches up to 366 mAh g −1 at 3.0 A g −1 , much larger than that of Sb 2 S 3 . Obtaining the full cell of Ni–Fe Prussian blue analog versus M-Sb 2 S 3 @DC, the reversible capacity is 330 mAh g −1 at 0.5 A g −1 . Supported by kinetic analysis, the excellent rate properties are determined by the surface-controlling behaviors, mainly resulting from the decreased capacitive resistance and improved ion moving. Furthermore, the reassembling evolution of active phases is revealed in detail by ex situ techniques. This work is expected to offer significant insights into interfacial evolutions toward advanced energy-storage systems.

With the fast growth of wearable intelligent devices, flexible sensors with a broad strain sensing range and high sensitivity are in urgent demand. Furthermore, the sensitivity of flexible wearable electronic devices to various signal capture depends on multiple interfacial bond interactions and a microstructure. However, a flexible sensor without multiple interfacial bonds has poor mechanical properties, low sensitivity/conductivity, and single sensing function to limit commercial sensor application. In this work, the novel dip-coating technique was used to design a flexible sensor based on polyvinyl alcohol with multiple interfacial bond interactions and a microcrack structure. Interestingly, the sensor exhibits high sensitivity with gauge factor > 100, a high conductivity of 356 mS m–1, impressive thermal sensitivity (0.01071 °C–1), a large strain of 344.5%, and excellent wear-resistance and durability. Possible sensing mechanisms under multiple stimuli have been presented. Moreover, flexible sensors with multiple signal monitoring can monitor real-time full-range human body motion and physical signal collection, providing a promising strategy to develop this sensor with outstanding performance in flexible sensor and sporting applications.

Carbon/transition metal oxide composites hold significant promise for energy storage applications; however, achieving precise control over the carbon structure to enhance the electrochemical activity of metal oxides remains a challenge. In this work, we utilized low-cost enzymatic lignin as a carbon source and harnessed the synergistic effects of magnesium oxide templates and potassium acetate activator to synthesize a lignin-derived hierarchical porous carbon (HPLC) characterized by a high specific surface area of 1704 ± 36 m 2 /g, well-ordered nanosheet structures, and hierarchical porosity. The comparative analysis demonstrated that HPLC exhibited superior pore anchoring and enhanced interfacial Mn-O-C bonding interactions with manganese dioxide compared to mesoporous carbon synthesized via magnesium oxide templating and microporous carbon derived from potassium acetate activation. This unique architecture significantly boosted the charge storage capacity of manganese dioxide. The composite showed remarkable electrochemical performance, achieving a specific capacitance of up to 567 F/g at a current density of 0.5 A/g, while also demonstrating excellent rate capability. An asymmetric capacitor constructed with the composite electrode delivered a high energy density of 47.22 Wh/kg and maintained a capacity retention of 85.2 % after 12,000 cycles at 2.0 A/g, illustrating its outstanding cycling stability. Analysis of the energy storage mechanism revealed that the capacity of this material was predominantly attributed to redox reactions involving manganese species induced by potassium ion insertion and extraction, as well as the double-layer capacitance arising from the adsorption and desorption of potassium ions. This work elucidates the crucial influence of carbon structure on the loading of metal oxides, providing a novel strategy for tuning carbon carrier structures aimed at developing high-performance carbon/metal composites.

The integration of ultrathin two-dimensional (2D) semiconductors with other conductive 2D materials to form hybrid electrocatalysts with abundant heterointerfaces can enhance the electrocatalytic activity by facilitating interfacial charge transfer. However, the hybrid electrocatalysts with weak interfacial bonding have limited effect on the electrocatalytic performance because the intrinsic activity of interfacial sites cannot be altered by weak interfacial interactions. As a proof-of-concept, we design ultrathin 2D–2D heterostructures with bridge-bonded Ni–O–Ti ligands based on single-layered Ti3C2Tx MXene and metal hydroxides, and further reveal the structure-activity correlation between interfacial bonding and electrocatalytic oxygen evolution reaction by combining theoretical and experimental studies. Density functional theory calculations reveal the modulation of the electronic structure of interfacial metal sites after the formation of bridged interfacial Ni–O–Ti bonding. Compared with the hydrogen-bond-linked heterostructure, the ultrathin 2D–2D heterostructure with bridge-bonded Ni–O–Ti ligands shows enhanced intrinsic activity and stability towards electrocatalytic oxygen evolution with a very low overpotential of 205 mV at 10 mA cm−2 and the long-term durability. This work provides a new understanding and approach for the design and development of 2D hybrid catalysts with highly efficient electrocatalytic activity.

Emergency prehospital wound closure and hemorrhage control are the first priorities for life-saving. A majority bioadhesives form bonds with tissues through irreversible cross-linking, and the remobilization of misalignment may cause severe secondary damage to tissues. Therefore, developing an adhesive that can quickly and tolerably adhere to traumatized dynamic tissue or organ surfaces in emergency situations is a major challenge. Inspiring by the structure of human serum albumin (HSA), a branched polymer with multitentacled sulfhydryl is synthesized, then an instant and fault-tolerant tough wet-tissue adhesion (IFA) hydrogel is prepared. The adhesive application time is just 5 s (interfacial toughness of ∼580 J/m2) and favorable tissue-adhesion is maintained after 10 cycles. IFA hydrogel remains unchangeable adhesive performance after one month of storage based on the internal oxidation-reduction mechanism. It not only can efficiently seal various organs, but also achieves effective hemostasis in models of the rat femoral artery and rabbit-ear artery. This work also proposes an effective strategy for controllable adhesion, which enables the production of asymmetric adhesives with on-demand detachment. Importantly, IFA hydrogel has sound antioxidation, antibacterial property, hemocompatibility, and cytocompatibility. Hence, the HSA-inspired bioadhesive can emerge as a promising first-aid supply for human-machine interface-based health management and non-invasive wound closure.
