Self-powered operation and broadband spectral adaptability are critical for the next generation of photodetectors, enabling sustainable performance and multispectral functionality. The broadband wavelength response capability can expand the application scenarios of a photodetector. However, achieving both broadband photoresponse and accurate wavelength recognition remains a significant challenge. Herein, we develop a self-powered photoelectrochemical photodetector based on Bi 2 Te 0.6 Se 2.4 /MoSe 2 heterojunctions, capable of identifying 254, 365, 546, and 650 nm and simulated sunlight with the assistance of machine learning. To achieve precise energy band alignment with MoSe 2 and enhance the heterojunction interface, the selenium content in Bi 2 Te 3-x Se x and the mass ratio of the composite components were systematically optimized. These structural optimizations improve charge carrier separation and transport via band structure engineering and interfacial modulation, resulting in superior photoelectrochemical performance. By integrating material design with machine-learning-assisted wavelength discrimination, this study demonstrates a multidisciplinary approach to broadband detection and highlights the potential of such devices in optical communication, environmental monitoring, and multispectral imaging applications.

The integration of heterostructure engineering with carbon materials exhibits significant advantages in enhancing ion transport efficiency and stability, buffering volume changes, and improving electrochemical lithium/sodium storage performance of transition metal selenide electrodes. In this study, we employ binary metal-organic frameworks as the precursors to successfully prepare rod-shaped composites assembled by carbon-coated bimetallic heterostructure nanoparticles (Cu 2-x Se/Bi 2 Se 3 @C) through a controlled selenization process at varying temperatures. The optimized Cu 2-x Se/Bi 2 Se 3 @C-600 composite demonstrate exceptional lithium storage capabilities, achieving high reversible capacities of 1102.3 mAh g −1 at 0.2 A g −1 after 100 cycles and 640.6 mAh g −1 at 1.0 A g −1 after 500 cycles. Ex-situ XRD analysis and theoretical calculations are utilized to elucidate the electrochemical reaction mechanisms and the benefits of the heterointerface in enhancing performance. The density functional theory calculation results indicate that the heterointerface in Cu 2-x Se/Bi 2 Se 3 reduces diffusion energy barrier of surface Li + ions and enhances electronic conductivity. The unique structure and composition advantages also grant the optimal composite superior sodium storage performance with high specific capacity (442.7 mAh g −1 at 0.2 A g −1 after 100 cycles), exceptional rate capability (297.3 mAh g −1 at 10.0 A g −1 ), and long-term cyclability (254.7 mAh g −1 at 5.0 A g −1 after 500 cycles).

Heterostructured anode materials have garnered significant attention in recent years due to their ability to optimize interfacial structures between different components. This design not only facilitates the formation of stable solid-electrolyte interphase (SEI) films but also enhances the overall electrochemical performance, including battery capacity and cycle stability. In this study, a novel N -doped carbon-modified NiSe 2 /FeSe 2 heterostructure combined with carbon nanotubes (NC@NFS/CNTs) composite was successfully synthesized via co-precipitation and gas-phase selenization. This material was subsequently applied as an anode for Na-ion batteries (NIBs). Based on the synergistic effect of the interfacial properties of the heterostructure and the highly conductive nature of CNTs, the NC@NFS/CNTs composite exhibited excellent electrochemical stability and superior long-term durability. The battery retains a capacity of 332.4 mAh g −1 after 5000 charge/discharge cycles a current density of 5 A g −1 . Moreover, the capacity retention rate remains as high as 77 % even after 10,000 cycles at an ultra-high current density of 40 A g −1 . Ex-situ XPS and XRD analyses, along with low-temperature EIS tests, demonstrate that the Na + storage properties of the NC@NFS/CNTs electrode are significantly enhanced. This improvement is primarily attributed to the heterojunction structure and the presence of highly conductive phases (CNTs and N -doped carbon layers), which effectively improve the electrode’s kinetic performance and enhance the stability of the SEI film.

The development of nickel-based multi-alloy catalytic electrodes for methanol oxidation reactions (MOR) holds significant potential for advancing new energy technologies. The study fabricated a biomorphic Ni 6 MnFeCoCu multi-element porous alloy foil via filter paper template-assisted impregnation and carbonization–reduction. The effect of selenization treatment on the phase composition, microstructure, and MOR performance of Ni 6 MnFeCoCu has been investigated. The results showed that biomorphic nickel-based multialloy foils inherited the porous fibers structure of the filter paper template. The main phase of Ni 6 MnFeCoCu are a face-centered cubic multi-element metallic phase and MnO phase. With increasing selenization temperature, the large particles on the surface of the fiber struts gradually presented; Ni in Ni 6 MnFeCoCu preferentially form NiSe 2 with Se, followed by Cu and Fe, resulting in the formation of biphasic nickel selenide (NiSe 2 and Ni 3 Se 4 ), Cu 2− x Se, and Cu 0.41 Fe 0.60 Se 1.99 at 400 ℃. The locally controlled charge, attributed to the synergistic effect of multi-metals and the incorporation of Se, enabled the optimized Ni 6 MnFeCoCu-Se 350 catalytic electrode to exhibit high methanol oxidation reaction (MOR) catalytic activity and excellent cycling stability. Compared to the current density value (@ 0.8 V) of the porous Ni p , the values of the Ni 6 MnFeCoCu and optimized Ni 6 MnFeCoCu-Se 350 increased by 13.3% and 30.4% for methanol oxidation, respectively. After a chrono-current test of 10,800 s, the current density of the electrode was retained at 92.2% of its original values. These findings provide a strategic pathway for designing lightweight, efficient, and durable multi-metal catalytic electrodes for sustainable energy applications. Graphical

The emergence of multidrug-resistant bacteria and persistent inflammatory responses have exacerbated the therapeutic difficulty of bacteria-infected pneumonia. There is an urgent need to find new strategies for synchronous sterilization and inflammation regulation for pneumonia. Herein, we developed maleimide-modified and alantolactone (Ala)-loaded copper indium selenide nanoparticles (ACIS NPs) to achieve near-infrared II (NIR-II) light-triggered photodynamic immunotherapy for multidrug-resistant Pseudomonas aeruginosa-infected pneumonia. After intranasal administration, they can quickly penetrate the mucus layer and then target P. aeruginosa and attach to its biofilm, achieving bacterial inactivation and biofilm elimination under NIR-II light irradiation. Simultaneously, ACIS NPs can also release Ala at the lesion site. They can not only stimulate the maturation of phagolysosomes in macrophages to increase phagocytosis efficiency but also downregulate the expression of NF-κB to reduce inflammatory cytokines and relieve the inflammatory level, thus promoting the polarization of macrophages toward an anti-inflammatory phenotype. Both in vitro and in vivo experiments have demonstrated that ACIS NPs can accumulate in lung tissues for killing P. aeruginosa and regulating macrophages, exhibiting high therapeutic efficacy against bacteria-infected pneumonia. This study demonstrates the potential of ACIS NPs as an alternative to traditional antibiotics, offers hope against bacterial resistance and the inhibition of biofilm formation, regulates the disordered inflammatory environment of the body, and provides a new strategy for bacteria-infected pneumonia therapy.

Decoupling the interrelated thermoelectric parameters is challenging for developing Ag 2 Se-based room temperature thermoelectrics. In this study, we construct specific grain boundary complexes that contain nano-sized TiO 2 and Au particles in Ag 2 Se through a one-step solvothermal process combined with spark plasma sintering. The decorated Ag 2 Se exhibits enhanced power factor due to the increased carrier concentration and maintained carrier mobility, while the introduced broadband phonon scattering effectively reduced thermal conductivity. The decoupled electrical and thermal transport properties result in a high zT value of 1.19 at 390 K in the Ag 2 Se decorated by 0.4 wt.% TiO 2 and 0.5wt.% Au, along with improved mechanical properties. The device assembled by using the optimal sample shows a maximum output power of 65 mW and a maximum energy conversion efficiency of 2.3% under a temperature difference of 80 K. The aging test results highlight the good stability of our devices. Therefore, constructing grain boundary complexes could be a promising strategy for developing practical Ag 2 Se thermoelectrics.

The pursuit of efficient, durable, and cost-effective oxygen evolution reaction (OER) electrocatalysts is of great significance for advancing sustainable energy technologies. Herein, a three-dimensional hierarchical N-doped carbon nanoflower encapsulated with nickel iron selenide (Ni 3 Se 4 /FeSe HNCNF) was fabricated via selenization of the iron salts decorated nickel coordination polymers. The obtained Ni 3 Se 4 /FeSe HNCNF presents abundant heterogenous interfaces, which effectively optimize the electronic configuration, substantially expediting charge-transfer kinetics. Additionally, the hierarchical nanoflower-like N-doped carbon framework maximizes the exposure of catalytic sites and restrains nanoparticle accumulation and erosion. Benefiting from these structural and compositional advantages, Ni 3 Se 4 /FeSe HNCNF delivers remarkable OER performance in alkaline medium (1.0 M KOH), achieving a low overpotential of 280 mV at 10 mA cm -2 , along with excellent durability exceeding 27 h at 10 mA cm -2 and 100 mA cm -2 . This study highlights the potential of heterostructure engineering and three-dimensional hierarchical design in bimetallic selenides, offering new insights into the development of next-generation high-performance OER electrocatalysts.

As display technologies mature, there is a growing demand for displays that offer superior visual quality. However, the development of high-resolution fabrication processes that are low-cost, simple, and scalable remains a significant challenge. Currently, established techniques like photolithography and inkjet printing face specific challenges. For instance, photolithography inevitably causes film damage during steps such as resist removal and etching, while inkjet printing is constrained by nozzle size and the coffee-ring effect, limiting further resolution improvements. This study employs an indirect transfer printing method, which utilizes a stamp fabricated via a two-step molding process. This stamp exhibits excellent solvent resistance, allowing it to define the pattern of the polymethyl methacrylate (PMMA) insulating layer and thereby indirectly achieve the patterning of the quantum dots. Additionally, a layer of PDMS is incorporated beneath the UV-adhesive stamp to enhance its overall elasticity, ensuring conformal contact with the target substrate during the transfer printing process. Compared to existing techniques for transferring insulating layers, our method significantly streamlines the fabrication workflow while maintaining high pattern fidelity and transfer success rates. Using this approach, we successfully fabricated green high-resolution devices with a resolution exceeding 6000 PPI and a maximum active area of 1 inch. This work provides a viable strategy and paves the way for high-resolution device fabrication.

Phase engineering of transition metal chalcogenides is a promising strategy for optimizing catalytic performance. In this work, we investigate the phase-dependent catalytic properties of NiSe. Using density functional theory (DFT) and Variable-cell nudged elastic band technique, we reveal a metastable intermediate phase (MIS-2′) within the confinement the of interface on the transition path from hexagonal (H–NiSe) to rhombohedral (R–NiSe) structures. Gibbs free energy calculations show that the MIS-2′ phase has superior hydrogen adsorption (ΔG H ∗ = −0.02 eV) compared to H–NiSe and R–NiSe. NiSe catalysts with different phases were synthesized by hydrothermal methods, and electrochemical tests in 1 M KOH show that the sample containing both MIS-2′ and R–NiSe prepared at 150 °C, delivers the best HER performance (η 10 = 105.08 mV, Tafel slope = 121.12 mV dec −1 ). This improvement is attributed to the synergistic effects of the two phases, especially the involvement of MIS. These findings highlight the potential of phase engineering to enhance catalytic activity and offer a new pathway for optimizing transition-metal chalcogenides based electrocatalysts for sustainable energy applications.

To enable fast sodium ion battery charging in a wide temperature range, the local structures of anode materials must be optimized to reduce the Na + diffusion resistance at the interface and inside the electrode. Guided by theoretical predictions, isotropic ReSe 2 with a 1 T phase crystal structure (1 T ReSe 2 ) is developed herein to exhibit enhanced electrical conductivity for efficient charge transfer compared to the 1 T' ReSe 2 phase. Enabled by its metallic characteristic and longer Re─Se bonds, 1 T ReSe 2 achieves a lower Na + diffusion barrier and lower adsorption energy than 1 T' ReSe 2 , facilitating faster Na + storage reaction kinetics. Operando spectroscopy characterization confirms that the 1 T ReSe 2 electrode can directly produce Na x ReSe 2 without undergoing a significant phase transition. This inhibits volume expansion, leading to improved cycling stability. As a result, 1 T ReSe 2 exhibits good fast-charging performance in a wide temperature range. A capacity of 197 mAh g −1 @20 A g −1 is maintained after 8000 cycles at room temperature, and a capacity of 136 mAh g −1 @1 A g −1 (corresponding to a capacity retention rate of 60%) is retained after 465 cycles at −40°C.

Electrocatalytic urea oxidation reaction (UOR) holds great promise in green energy conversion and pollutant degradation with low energy-consumption. Herein, Fe-NiTe/NiSe 2 nanosheets array with super-hydrophilic/aerophobic surface and enhanced built-in electric field is constructed. The surface hydrophilic/aerophobic properties enabling rapid bubble nucleation and efficient detachment, liberating covered active sites, thus improving the surface adsorption kinetics of urea molecular and OH − . Moreover, Fe incorporation accelerates charge transfer and modulates the built-in electric field at the NiTe/NiSe 2 heterojunction interface. This reduces the surface reconstruction potential and optimizes the occupancy of hybrid anti-bonding (d-δ)* orbitals, leading to the formation of electron-rich region (Fe-NiTe) and electron-deficient region (Fe-NiSe 2 ), which preferentially adsorbs the electron-withdrawing (C═O) and electron-donating (─NH 2 ) groups of urea, respectively, thereby optimizing the adsorption energy of urea molecules. Therefore, the Fe-NiTe/NiSe 2 heterojunction exhibits excellent alkaline UOR performance, requiring only 1.447 V RHE to deliver a current density of 100 mA cm −2 , which it can maintain for over 90 h. The Fe-NiTe/NiSe 2 (+) ∥ Pt/C (-) urea electrolyzer can maintain stable for 150 h at 100 mA cm −2 . This work offers a macro- and microscopic coupling engineering strategy to address the surface and intrinsic properties for alkaline UOR, holding significant practical value for advancing energy-efficient hydrogen production and wastewater treatment.

Flexible thermoelectric materials offer a promising route toward self-powered wearable electronics. The emergence of ductile inorganic semiconductors opens a new paradigm for flexible TE technologies, yet their thermoelectric performance remains far from optimal. Herein, we reveal a pronounced phase-transition hysteresis in the Ag 2 (S, Se, Te) system, where the transition temperature during cooling is 20–40 K lower than that during heating. Leveraging this hysteresis behavior, we successfully stabilize different structural phases at ambient conditions simply by varying the thermal treatment protocol. Compared to the monoclinic phase obtained by slow cooling from high temperature, the orthorhombic phase obtained by liquid-nitrogen treatment exhibits worse plastic deformation but much better electrical transport. A maximum power factor of ∼16 µW cm −1 K −2 and a zT of ∼0.5 near room temperature are achieved in the orthorhombic phase, both of which surpass most reported Ag-based ductile thermoelectric materials. This work provides a new pathway for designing high-performance ductile thermoelectrics.
