Driven by the escalating demand for cutting-edge materials in interactive encryption and customized display, the optimization of excitonic coupling mechanisms in perovskite-based luminescent systems has emerged as a pivotal focus in advanced materials research. Inspired by synergistic doping (SD), a photoswitchable energy transfer channel is realized utilizing the UV-responsive Cs 2 NaInCl 6 : Sb 3+ -Ho 3+ (CNIC: Sb-Ho) phosphor. Benefiting from the self-trapped exciton of Sb 3+ , the visible blue luminescence of Ho 3+ achieves excitation reconstruction through SD, with a sensitization coefficient from Sb 3+ to Ho 3+ in CNIC reaching two orders of magnitude. Notably, CNIC: Sb-Ho quantum dot is embedded into polyacrylonitrile (PAN) and polymethyl methacrylate (PMMA) fibers, respectively, and distinct color coordinate channels are created by altering the doping concentration and fiber matrix, thereby enabling the personalization and the customization of the desired colors with enhanced precision. Furthermore, excellent read-in performance under UV irradiation is achieved by screen-printing CNIC: Sb-Ho microcrystal on nanofibers and combining it with ACSII code, which endows nanofibers with UV-induced controllable shape programming behavior for interactive multidimensional information encryption. This work establishes an enhanced visual interaction framework through effectively integrating perovskite fluorescence tunability and nanofiber adaptive structures, thus opening new possibilities for the smart application of next-generation optical encryption technology.

Herein, using three-dimensional interconnected bacterial cellulose (BC) as substrate, we prepare a wearable polyaniline (PANI)-based ammonia sensor via co-doping method with sulfosalicylic acid (SSA) and poly(2-acrylamido-2-methyl-1-propane sulfonic acid) (PAMPS). The introduction of SSA is intended to improve the intrachain carrier mobility of PANI, while the simultaneous doping of PAMPS is responsible for efficient interchain charge transfer, resulting in a significant synergy in carrier mobility and sensitivity enhancements. Moreover, with high specific surface area and 3D network, BC substrate is beneficial to enhance the contact area with detected gas as well as the mechanical tolerance during the practical utilization. Consequently, our PANI-SSA/PAMPS-based sensor performs a high response (21.3 for 50 ppm ammonia), quick response and recovery time (4.1 s/16 s). Furthermore, the sensor also demonstrates excellent ammonia selectivity among different interfering agents, with a lower detection limit (LOD) of 10 ppb at room temperature , and the limit sensing temperature even below -10 °C. Our work provides more opportunities for the design of flexible gas sensor in sensing application.

The development of non-precious metal electrocatalysts with remarkable activity is a major objective for achieving high-efficiency hydrogen generation. Here, a trimetallic electrocatalyst with a dendritic nanostructure, which is denoted as NiMoCu-NF, was fabricated on nickel foam via a gas-template electrodeposition strategy. By virtue of the metallic doping and structural optimization, NiMoCu-NF exhibits superior HER electrocatalytic activity with an overpotential of 52 mV at 10 mA cm−2. Additionally, the NiMoCu-NF-derived nickel-based (oxy)hydroxide species in the oxidation operating state deliver considerable electrocatalytic urea oxidation reaction (UOR) performance to match the efficient H2 generation, with a low voltage of 1.54 V to realize overall electrolysis at 50 mA cm−2. Impressively, combined experimental and simulation analysis demonstrate that the NiMoCu-NF with a favorable 3D nanostructure feature effectively regulates the heterogeneous interface states, inducing a “Gas Microfluidic Pumping” (GMP) effect that improved electron–mass transfer properties to accelerate the electrocatalytic reaction kinetics of either the HER or UOR.

The liquid mineral intermediates are very important for the formation of different biominerals in biological systems. However, the detail growth mechanisms of these amorphous phases in complicated biochemical condition, such as organic frameworks, special interfaces and compartmented cells, are still incomplete understand. To gain a better understanding of the evolution of the polymer-induced liquid mineral precursor (PILP) in the special microenvironments, the nanopores of track etch (TE) membranes have been applied. Simultaneously, several synergetic ions of Sr 2+ , Mg 2+ and Ba 2+ were introduced to tune properties (nucleation time, lifespan and flowability) of liquid mineral phases. Simultaneously, the titration experiments have also been performed to track the crystallization processes. Experiments have shown that the nanopores could effectively stabilize the metastable vaterite crystals. Under the influences of polymer, nanopores and synergetic doping ions, mono- and polycrystalline nanorods could be synthesized. Doping ions in a certain concentration rang could effectively postpone the nucleation time and prolong the lifespan of liquid mineral precursor. Our study will be helpful to understand the crystallization process of different amorphous phases in the complicated biological microenvironments.

Layered oxide cathode materials may undergo irreversible oxygen loss and severe phase transitions during high voltage cycling and may be susceptible to transition metal dissolution, adversely affecting their electrochemical performance. Here, to address these challenges, we propose synergistic doping of nonmetallic elements and in situ electrochemical diffusion as potential solution strategies. Among them, the distribution of the nonmetallic element fluorine within the material can be regulated by doping boron, thereby suppressing manganese dissolution through surface enrichment of fluorine. Furthermore, in situ electrochemical diffusion of fluorine from the surface into the bulk of the materials after charging reduces the energy barrier of potassium ion diffusion while effectively inhibiting irreversible oxygen loss under high voltage. The modified K0.5Mn0.83Mg0.1Ti0.05B0.02F0.1O1.9 layered oxide cathode exhibits a high capacity of 147 mAh g–1 at 50 mA g–1 and a long cycle life of 2200 cycles at 500 mA g–1. This work demonstrates the efficacy of synergistic doping and in situ electrochemical diffusion of nonmetallic elements and provides valuable insights for optimizing rechargeable battery materials.

Copper-based materials have emerged as promising anode candidates for next-generation lithium–ion batteries owing to their high theoretical capacity. However, their practical implementation remains fundamentally constrained by inherent semiconducting characteristics and sluggish reaction kinetics. To address these limitations, we develop a universal low-temperature multimetal synergistic doping strategy to construct a high-entropy Cu-based material library (HE-CBMs) encompassing 54 distinct compositions. Through precise modulation of coordination environments and stoichiometric ratios across eight transition metals (Cr, Mn, Fe, Co, Ni, Cu, Zn, and Cd), we first synthesized HE-doped Cu2O (HE-Cu2O) nanospheres via a solvothermal approach, followed by low-temperature reduction to achieve HE-doped metallic Cu (HE-Cu) nanospheres. The multimetal synergy induces lattice distortion and electron-deficient states, synergistically reducing Li+ diffusion barriers while optimizing interfacial charge transfer kinetics. The optimized octonary HE-Cu anode (CrMnFeCoNiCuZnCd) demonstrates exceptional electrochemical performances, delivering a high reversible capacity of 2211.2 mAh g–1 after 250 cycles at 1 A g–1 and retaining 1270.4 mAh g–1 over 900 cycles at 5 A g–1, outperforming most current Cu-based anodes. This work establishes a scalable combinatorial platform for HE material synthesis under mild conditions while elucidating fundamental principles of multimetal synergy for next-generation energy storage systems.

The crystalline morphology of perovskite film plays a key role in determining the stability and performance of perovskite solar cells (PSCs). In addition, the work function and conductivity of hole transport layer (HTL) have a great influence on the effciency of PSCs. Here, we develop a synergistic doping strategy to fabricate high-performance inverted PSCs, doping a functional nanographene (C78-AHM) into the poly[bis(4-phenyl)(2,4,6-trimethylphenyl)amine (PTAA) HTL, thus forming an HTL with higher conductivity, lower roughness, and frontier energy levels matching the perovskite absorber work function. On this basis, thiosemicarbazide (TSC) was doped into the precursor solution of perovskite as the grain and interface modifier to further improve the crystalline morphology of perovskite film. Compared with the current single passivation method, this codoping strategy can simultaneously reduce the surface and bulk defects of perovskite film and reduce the interface energy barrier. Eventually, high-quality TSC-doped perovskite films based on C78-AHM-doped PTAA HTL are obtained with over 2 μm sized grains, pinhole-free, and improved crystallinity. As a result, this synergistic doping strategy increases the efficiency of the device from 20.27% to 23.28%. Furthermore, the environmental and thermal stabilities of the devices are significantly improved. Therefore, this work provides a simple way for the preparation of other efficient optoelectronic devices.

Accurate measurement of hydrogen peroxide is of great significance in monitoring human diseases and environmental safety. At present, there are a variety of testing methods, among which the use of electrochemical sensors to accurately measure hydrogen peroxide has gradually become a research hotspot. In this article, phytic acid (PA) with dual functions of doping and cross-linking and HCl with strong ionization capacity was introduced as dopants to co-doping polyaniline, and polyaniline hydrogel with a three-dimensional network structure was prepared. The influence of the HCl/PA co-doping ratio on conductive polyaniline hydrogel (CPAniH) was explored. The synthesis process and mechanism of HCl/PA-CPAniH were analyzed and explained. In addition, the conductivity and mechanism of HCl/PA-CPAniH, as well as the hydrogel characteristics were characterized and studied. A new electrochemical sensor based on polyaniline hydrogel and silver nanoparticles was constructed to detect hydrogen peroxide. The sensor has a good linear relationship, a wide linear range, and a high-detection limit for H 2 O 2 . In addition, it also shows that HCl/PA-CPAniH is a good interface material for electrochemical sensors and has a certain application potential.

Among some practical O3-type layered oxide cathodes, NaNi 1/3 Fe 1/3 Mn 1/3 O 2 (NFM) features a high specific capacity and moderate cyclability. However, sluggish Na + transfer kinetics, low structural stability, and rapid capacity loss during long-term cycling, are still posing a challenge to commercial applications of this material. In this work, we propose a Mg and Cu co-doped O3-type NaMg 0.02 Cu 0.02 Ni 0.33 Fe 0.27 Mn 0.36 O 2 (MC-NFM) with a stable structure and good cycling stability. It was found that the Mn O bonds in MC-NFM are obviously reinforced by synergistic doping with small amounts of Mg and Cu, leading to enhanced structural robustness, decreased Na + migration barrier, and delayed O3-P3 phase transition. As a result, longer cycle life and enhanced rate performance are achieved. MC-NFM can yield a specific capacity of 142.1 mAh g −1 at 0.1C and 116.0 mAh g −1 at 5C, and maintain 83.6 % of its initial capacity after 400 cycles at 1C. This work provides a promising design of O3-type cathode for sodium-ion batteries.

Herein, we synthesized well-dispersed N and Fe-doped CoS 2 (FNCS) with stable sulfur vacancies (S V ) for Fenton-like reaction. The characterization, experimental, and calculation results jointly unveiled the synergistic modification of heteroatoms and defects within FNCS constructed unique Co−N−Fe···S V sites, enabling synchronous activation of peroxymonosulfate (PMS) and dissolved oxygen (DO). Optimized S 3p-Co 3d orbital hybridization facilitated efficient electron cycling, generating both SO 4 •− radicals and singlet oxygen ( 1 O 2 ) at Co−N−Fe···S V sites. Consequently, the FNCS/PMS system, operating via a radical-nonradical synergistic mechanism, achieved an ultra-high pollutant degradation rate constant of 2.71 min⁻¹ , 3.77 times higher than radical-dominated CoS 2 /PMS, while retaining over 90 % of its initial activity after 10 h of operation with strong interference resistance. This work provides a clear perspective on regulating the electronic structure of active sites to synergistically activate multiple oxidants for enhanced Fenton-like catalysis.

Metal–organic framework (MOF) nanosheets with attractive chemical and structural properties have been considered as prominent oxygen evolution reaction (OER) electrocatalysts, while the insufficient exposed active sites and low electrical conductivity of MOFs limit their electrocatalytic activity and further industrial applications. Herein, a unique strategy to remarkably boost electrocatalytic OER activity of one Ni-based MOF is developed by the simultaneous incorporation of Fe3+ ions and BF4– anions within its layer structure. The optimized electrocatalyst NiFe-MOF-BF4–-0.3 NSs shows superior OER activity with a required ultralow overpotential of 237 mV at 10 mA cm–2, a small Tafel slope of 41 mV dec–1, and outstanding stability in an alkaline medium. The experimental and density functional theory (DFT) calculation results verify that the interactions between metal (M) ions and BF4– anions (defined as M···F, M = Ni or Fe) in this catalyst can adjust the adsorption abilities of oxygen intermediates and lower the free energy barrier of the potential-determining step by tailoring its electronic structure, thereby remarkably boosting its OER activity. This protocol provides new insights into surface and structure engineering of 2D MOFs, leading to greatly enhanced electrocatalytic OER performance.
