The vaporization-condensation-conversion method is the prominent technique used for synthesizing red phosphorus/carbon (P/C) composites. However, its practical application is limited by the inevitable formation of toxic white phosphorus (WP) residues, posing severe safety concerns. Theoretical calculations of the WP polymerization process performed in this study revealed that the introduction of iodine can considerably accelerate the polymerization of WP molecules, yielding P/C composites free of WP residues. Furthermore, in the resulting iodine-doped P/C (I-P/C) composites, iodine forms I-P bonds, considerably enhancing electronic conductivity and promoting faster Na-P redox kinetics compared to those in the original P/C composites. Consequently, an I-P/C electrode exhibited a capacity of 1193 mA h g⁻ 1 , retaining 100 % of its capacity after 100 cycles at 0.2 A g⁻ 1 . Furthermore, an assembled I-P/C||Na 3 V 2 (PO 4 ) 2 F 3 full cell retained 91.9 % of its capacity after 200 cycles at 0.5 A g⁻ 1 . Additionally, the full cell exhibited a high energy density of 132.2 W h kg⁻ 1 at a power density of 9942.1 W kg⁻ 1 , demonstrating potential to complete charging or discharging within ∼57 s. Finally, an I-P/C||Na 3 V 2 (PO 4 ) 2 F 3 pouch cell, with a capacity of 0.36 A h, demonstrated excellent cycling performance even after 150 cycles at 0.05 A g⁻ 1 .

With the aging global population and a progressive annual rise in chronic diseases, the incidence of chronic skin trauma has increased significantly. Chronic skin wounds, which often remain unhealed for extended periods, are highly susceptible to bacterial infections. Consequently, the use of antibacterial dressings has become a crucial strategy for preventing and managing such infections. These dressings not only serve as a physical barrier protecting wounds from external contaminants, but also regulate the healing microenvironment, promote tissue regeneration, and accelerate the healing process. In this study, we designed a wound dressing with Janus structure by electrospinning technology. The inner layer consists of hydrophilic cellulose acetate (CA) incorporated with polylysine (ε-PL) to maintain a moist, bacteriostatic environment, while the outer layer is composed of hydrophobic polycaprolactone (PCL) integrated with tannic acid (TA)-modified black phosphorus (BP) to prevent microbial adhesion. The combination of the antibacterial activity of ε-PL and the photothermal effect of TA-modified BP (TABP) endows the Janus nanofiber membrane with a potent synergistic antibacterial capability. In vitro experiments demonstrate that the dressing exhibits excellent surface wettability and permeability, enhanced mechanical strength, potent antibacterial activity, and mild photothermal effects that help alleviate inflammatory responses. This Janus nanofiber membrane represents a promising strategy for enhancing and accelerating wound healing.

Coupling solar-powered CO 2 conversion with pollutant removal via Z -scheme heterojunctions offers a promising strategy to simultaneously address energy and environmental challenges. However, achieving efficient charge separation and optimizing active sites for both reduction and oxidation reactions are still significant challenges. Herein, a Z -scheme heterojunction photocatalyst with spatially separated dual active sites (hydroxyl-functionalized red phosphorus (HRP) and amino-functionalized graphitic carbon nitride (ACN)) was developed to enable the concurrent photoreduction of CO 2 and photooxidation of tetracycline (TC). The optimized heterojunction, incorporating 1.25 wt% HRP, achieved a 4.96-fold increase in CO yield and 1.09-fold improvement in TC degradation compared with a red phosphorus/graphitic carbon nitride (RP/CN) system without surface functionalization. Density functional theory calculations and experimental analyses confirmed a Z -scheme charge transfer mechanism wherein hydroxyl groups facilitated hole-mediated TC oxidation and amino groups promoted electron-driven CO 2 reduction. The 1.25HRP/ACN photocatalyst demonstrated an electron transfer efficiency of 87.8 %, significantly surpassing the 64.9 % observed for 1.25RP/CN, highlighting the synergistic benefits of dual-site engineering. This study provides detailed insights into dual-functionalized Z -scheme heterojunctions with spatially separated redox-active sites, advancing the design of integrated systems for solar fuel generation and environmental remediation.

Interfacial modification strategies for lithium metal anodes have emerged as a promising method to improve cycling stability, suppress lithium dendrite growth, and increase Coulombic efficiency. However, the reported chemical synthesis methods lead to side reactions and side products, which hinder their electrochemical performance. In this study, we propose a novel and facile red phosphorus-assisted solid-state friction method to in situ fabricate a uniform Li3P interphase directly on the surface of lithium metal. Interestingly, the as-formed artificial Li3P interphase with high ionic conductivity and lithium affinity features significantly enhanced interfacial stability and electrochemical kinetics. The symmetric cells based on Li@P with the Li3P interphase achieved a prolonged lifespan, over 1000 h, at 1 mA/cm2with low polarization. When paired with a high-loading LiFePO4cathode (10.5 mg/cm2), the Li@P||LiFePO4full cell retained 88.9% of its capacity after stable cycling for 550 cycles at 2 C and further demonstrated the excellent performance and stability of the Li@P‖LiCoO2full pouch cell. This study provides an efficient and scalable strategy for stabilizing lithium metal anodes, expanding new ideas for the development of next-generation high-energy-density batteries.

The high recurrence and metastasis rates of renal cell carcinoma (RCC) necessitate novel therapeutic strategies. Although chemotherapy is widely used, it often leads to systemic toxicity and acute kidney injury (AKI). This study developed a near-infrared (NIR)-responsive two-dimensional black phosphorus (BP) nanosheet drug delivery system loaded with doxorubicin (DOX) for photothermal therapy (PTT) of RCC, aiming to reduce nephrotoxicity. BP nanosheets exhibit excellent photothermal conversion efficiency under NIR irradiation, enabling localized hyperthermia for tumor ablation and triggering DOX release. Both in vitro and in vivo experiments demonstrated that BP-DOX induces apoptosis in RCC cells and suppresses tumor growth upon NIR irradiation. This study further revealed that this nanocomposite alleviates oxidative stress and inflammation in renal tissues, thereby preserving renal function. This work highlights the potential of the BP nanoplatform for synergistic chemotherapy–photothermal therapy in RCC while mitigating kidney damage, offering a new approach to overcome chemotherapy-related complications.

Renewable-powered electrochemical CO2 reduction (ECO2R) provides a sustainable route to convert CO2 into valuable fuels and chemicals. However, conventional ECO2R systems face high energy costs due to the sluggish oxygen evolution reaction (OER) at the anode. Replacing the OER with biomass electrooxidation (e.g., glycerol oxidation reaction, GOR) can lower energy consumption while coproducing high-value chemicals. However, the construction of an efficient and cost-effective bifunctional catalyst remains a challenge. Herein, we design a low-cost, bifunctional Ni12P5@NCNT catalyst with a bamboo-like nanotube morphology for coupled ECO2R and GOR. The Ni12P5@NCNT exhibits exceptional performance, achieving 82% CO selectivity at −0.7 V vs RHE in ECO2R and a 95% Faradaic efficiency for formate production in GOR. The integrated system significantly reduces overpotential (219 mV) compared to conventional ECO2R //OER setups. Experiments reveal that the strong electronic interaction between Ni12P5 and NCNT enhances the CO2/glycerol adsorption and accelerates charge transfer, boosting both ECO2R and GOR activity. This work provides a promising strategy for co-upgrading CO2 and glycerol into valuable products using nonprecious metal catalysts.

Phosphorus nanoribbons combine the tunable bandgap and high mobility with the inherent anisotropy of one-dimensional systems, offering promise for functional electronics, but their intrinsic low stability hinders practical applications. Here, we report phosphorus-lithium double-helix nanoribbons with a well-ordered helical architecture and high structural stability under harsh conditions such as in air up to 225°C, water, and even acidic solutions. Comprehensive experimental characterizations and theoretical analyses show that the stability arises from a synergistic combination of Zintl phase formation between phosphorus and lithium atoms, noncovalent interhelical interactions, and geometric protection offered by the distinctive helical architecture. The nanoribbons show tunable optical properties dependent on temperature, thickness, and polarization state. It is demonstrated that these properties enabled nanoribbon-based hydrogels with self-healability and highly efficient photothermal conversion, showing a general approach for stabilizing active low-dimensional materials and paving the way for applying phosphorus-based nanostructures in biomedical engineering and quantum technologies.

The call for green economy has accelerated the research development of energy-saving optoelectronic devices. The choice of photoelectric material and the design of device configuration are crucial for achieving high device performances. In this study, we investigated the photoelectric response behaviors of van der Waals (vdW) heterostructure photodetectors by employing a type-II MnPSe 3 /MoS 2 heterojunction for charge carrier transport. Two types of device architectures were designed, one has a vertically stacked heterostructure with the photogenerated carriers transferring in an out-of-plane direction in the overlapped area of both materials; the other utilized the photogating effect using the top MoS 2 as the photogate for the carrier distribution modulation and MnPSe 3 at the bottom as the carrier transport channel. Both PDs demonstrated a broadband photoelectric response in the range of 254-1020 nm under the biased condition. Besides, the former device demonstrated a distinct self-powered behavior with the spectral detection range spanning from 365 nm to 635 nm, which was ascribed to higher charge carrier separation efficiency by the built-in electric field of the MnPSe 3 /MoS 2 heterojunction and the asymmetric barrier heights between two metal-semiconductor interfaces. This study reveals the possibility for harnessing the MnPSe 3 /MoS 2 hybrid vdW in low-power consuming optoelectronic devices and its application potential in broadband photoelectric detection.

Spin Seebeck effect refers to the creation of spin currents due to a temperature gradient in the magnetic materials or across magnet-normal metal interfaces, which can be electrically detected through the inverse spin Hall effect when in contact with heavy metals. It offers fundamental insights into the magnetic properties of materials, including the magnetic phase transition, static magnetic order, and magnon excitations. The behavior of the spin Seebeck effect across the spin-flop transition has been extensively studied, whereas the spin Seebeck effect across the spin-flip transition remains poorly understood. Here, we demonstrate the spin Seebeck effect in a weakly exchange-coupled van der Waals antiferromagnet CrPS 4 . The spin Seebeck effect increases as the magnetic field increases before the spin-flip transition due to the enhancement of the thermal spin current as a function of the applied field. A peak of spin Seebeck effect is observed at the spin-flip field, which is related to the magnon mode edges across the spin-flip field. Our results extend spin Seebeck effect research to van der Waals antiferromagnets and demonstrate an enhancement of spin Seebeck effect at the spin-flip transition.
