Efficient and corrosion-resistant electrocatalysts are essential for the oxygen evolution reaction (OER), particularly in chloride-containing electrolytes such as seawater. Herein, a self-supported NiS 2 –MnS heterostructured catalyst grown on nickel foam (NiS 2 –MnS/NF) was fabricated through a combined electrodeposition–sulfidation strategy. Structural characterizations reveal the formation of a nanosheet-based heterostructure with uniformly distributed elements and abundant exposed active sites. In 1 M KOH electrolyte, the NiS 2 –MnS/NF electrode requires overpotentials of 269 and 355 mV to achieve current densities of 20 and 100 mA cm −2 , respectively, together with a small Tafel slope of 36 mV dec −1 and stable operation for 100 h. In simulated seawater electrolyte containing 1 M KOH and 0.5 M NaCl, the catalyst still maintains excellent OER activity, delivering overpotentials of 236 and 320 mV at the same current densities. The improved catalytic performance is attributed to the electronic interaction between NiS 2 and MnS phases and the structural evolution of the catalyst during OER. Post-OER characterizations indicate that the sulfide precursor undergoes in situ reconstruction to form NiOOH and MnOOH active species, which contributes to the enhanced catalytic activity. This work provides a promising strategy for designing efficient and corrosion-resistant electrocatalysts for seawater electrolysis.

In this paper, the successful fabrication of NiMoO4/MnS composite electrodes was in situ growth on nickel foam (NF) substrates via a two-step hydrothermal methods. The in situ growth strategy effectively maintains integrity of the structure while eliminating interfacial contact resistance, significantly enhancing the material’s electrical conductivity. This structural design strategically integrates the high theoretically capacitance of NiMoO4 with the superior conductive properties of MnS, creating abundant electrochemical active sites and synergistic effects. Consequently, the NiMoO4/MnS/NF electrode achieves a remarkable 9225.6 mF cm–2 areal capacitance at a current density of 4 mA cm–2, significantly surpassing the performances of individual NiMoO4/NF (2667.6 mF cm–2) and MnS/NF (492.8 mF cm–2) electrodes. Furthermore, the assembled asymmetric supercapacitor (ASC) device delivers a high energy density of 0.26 mWh cm–2 at a power density of 3 mW cm–2. This study not only provides an innovative design concept for constructing heterogeneous transition metal composite materials but also establishes a scalable application foundation for developing future high-efficiency energy storage technologies.

As a potential cathode material, manganese-based sulfide has recently attracted increasing interest due to its many advantages in aqueous zinc-ion storage. Unfortunately, some challenges such as sluggish kinetics, unstable structure, and controversial phase transition mechanism during the energy storage process hinder its practical application. Herein, inspired by density functional theory (DFT) calculations, a novel 3D sulfur vacancy-rich and heterostructured MnS/MXene aerogel is designed, and used as a cathode for aqueous Zn-ion batteries/hybrid capacitors (ZIBs/ZICs) for the first time. Thanks to the synergistic modification strategy of sulfur vacancies and heterostructures, the as-constructed MnS/MXene//Zn ZIBs exhibit significantly enhanced electrochemical properties, especially outstanding rate capability and cyclic stability. More encouragingly, the as-assembled MnS/MXene//porous carbon (PC) ZICs exhibit an ultrahigh energy density, a high power density, and a splendid cycling lifespan. Most notably, systematic kinetic analyses, ex situ characterizations, and DFT calculations illustrate that MnS/MXene first irreversibly converts into MnO x @ZnMnO 3 /MXene, and then undergoes a reversible conversion from MnO x @ZnMnO 3 /MXene to MnOOH@ZnMn 2 O 4 /MXene, accompanied by the co-insertion/extraction of H + and Zn 2+ . The synergistic modification strategy of sulfur vacancies and heterostructures and the thorough mechanistic study proposed in this work offer valuable guidance for designing and exploiting high-performance cathodes in aqueous zinc-based energy storage devices.

Supercapacitor is one of well-known energy-storage devices. However, the electrode materials still restrict its performance and reduce its practical value due to low capacitance or high cost. Therefore, it is of vital importance to pursue the cheap electrode materials with high performance for the next generation supercapacitor. Herein, a series of bimetal sulfide MnS/Cu 2 S/C composite materials were synthesized by hydrothermal reaction and the subsequent calcination with expired manganese gluconate and copper gluconate as the starting materials. Moreover, the effect of Cu 2 S's content on the microstructure and capacitance of MnS/Cu 2 S/C bimetal sulfides was further investigated. All the composites showed the well-organized morphology of about 3 nm metal sulfide nanoparticles embedded in the carbon microspheres with a diameter of about 6 μm. When the feeding ratio was 2:1, the reversible specific capacitances of 2MnS/Cu 2 S/C (MCS-2) in the three-electrode and two-electrode systems were as high as 1206 F/g and 116 F/g at 1.0 A/g, respectively, higher than those of other samples. The synergistic effect of the bimetal sulfides and the joint contributions of high conductivity and low capacitance of Cu 2 S may be responsible for the desirable high supercapacitance. Additionally, the successful conversion of expired gluconates to the useful electrode materials in this work highlighted the ecological benefits and the positive effect on the environmental protection and the resource conservation.

α- and γ-MnS materials were successfully prepared by a simple hydrothermal method. A thorough investigation was conducted into the phase evolution, morphology, and electrochemical performances. It is found that excessive water shifts the growth of MnS powders to thermodynamic regimes, and the Ostwald ripening process favors the formation of thermodynamically stable α-MnS, while pure γ-MnS can only be prepared with a mixture of ethylene glycol (EG) and water. Both α- and γ-MnS electrodes deliver remarkable electrochemical performances, demonstrating specific capacities of 320 and 477 F/g at 1 A/g and capacity retention rates of 90 and 72% after 3000 cycles at 5 A/g, respectively, outperforming the electrochemical performances of α- and γ-MnS electrodes reported in former literature. The superior specific capacity of γ-MnS to that of α-MnS can be ascribed to its stacked layered structure, which is more conducive to the accommodation of ions.

The search of an efficient and stable electrode material has led to the growing interest in using transition metal-based nanocomposites in supercapacitors. In this work introduces the NiSe 2 -MnS hybrid material synthesized by a low-cost solution to overcome the shortcomings of single-component systems to exploit dual-phase synergy. MnS was incorporated in NiSe 2 , which has good conductivity of electricity, and the combination of both leads to an electrochemical compound having enhanced performance. Effective formation of the NiSe 2 -MnS nanostructure with good integration was confirmed by careful structural and morphological studies. Electrochemical analysis revealed that the composite had a spectacular specific capacitance of 835 F/g in three- electrode system and 134 F/g in two- electrode set up. Interestingly, the electrode still had 85.1%, After 5,000 consecutive charge -discharge cycles at a current density of 8 A/g, the material still had a considerable fraction of its initial capacitance, which shows its excellent cycling stability. In general the NiSe 2 -MnS hybrid system is a cost effective but very efficient pathway to the future of energy storage.

In the present work, three kinds of γ-MnS with different morphologies were prepared by solvothermal method and employed to improve the hydrogen storage properties of MgH 2 . It was found that spherical γ-MnS had the best catalytic activity. The influences of γ-MnS content and milling time on the hydrogen storage performance of MgH 2 were investigated. The initial hydrogen release of MgH 2 -5(γ-MnS)-5 h composite started at 241 ℃, 4.61 wt% of hydrogen was desorbed within 20 min at 270 ℃, and 4.24 wt% of hydrogen was absorbed within 10 min at 150 ℃. The apparent activation energies of hydrogen absorption and desorption of MgH 2 -5(γ-MnS)-5 h composite decreased to 45.1 and 63.6 kJ/mol, respectively. In addition, the composite also exhibited good cycle performance, which could keep stable in 60 cycles. The results of SEM and TEM declared that the catalyst was uniformly distributed on the matrix during the cycling process, and the worm-like morphology of the sample also had a positive effect on the stability of kinetics. XPS analysis of Mn 2p in the samples showed that only characteristic peaks of γ-MnS 2p were observed in the ball-milled samples, but the characteristic peaks of Mn 2p and α-MnS 2p were observed in the first and tenth hydrogenated samples, while only the peaks of Mn 2p were observed in the sixtieth hydrogenated sample. The formation of Mn not only greatly weakened the Mg-H bond, but also led to a slight increase in cycle capacity. Therefore, γ-MnS-doped MgH 2 manifested a good comprehensive hydrogen storage performance.

Lithium‑carbon dioxide (Li-CO 2 ) batteries, combining high energy density with carbon dioxide conversion capability, were recognized as a promising next-generation energy storage system. However, their practical application is still hindered by the sluggish kinetics of the carbon dioxide reduction reaction (CO 2 RR) and the carbon dioxide evolution reaction (CO 2 ER). Herein, a self-supporting heterostructure catalyst composed of amorphous CoS x and crystalline MnS (a-CoSₓ/c-MnS) has been designed based on an amorphous/crystalline interface synergistic strategy. This unique interface induces strong electronic coupling and charge redistribution, which optimizes the adsorption of reaction intermediates and thereby significantly enhances the bifunctional activity for both CO 2 RR and CO 2 ER. Simultaneously, the three-dimensional (3D) urchin-like open architecture provides multi-level channels for electron, ion, and gas transport. The interface regulates Li 2 CO 3 discharge products into a loose, porous network of blocky crystal clusters effectively, enabling easier decomposition and mitigating passivation. The Li-CO 2 battery based on the a-CoSₓ/c-MnS cathode exhibits an ultra-low overpotential of 0.22 V, a high Coulombic efficiency of 98.62% and an energy efficiency of 91.38%. Furthermore, the battery demonstrates stable cycling for over 2000 h at a limited capacity.

To break through the inherent limitations of the energy density of supercapacitors, this study innovatively adopted the metal-organic framework (MOF) template-guided strategy to synthesize the Mn/Co-BTC precursor by solvothermal method. Heterostructured MnS@Co 1-x S bimetallic sulfide composites were successfully prepared by two-step vulcanization calcination. The material fully combines the structural advantages derived from MOF with the bimetallic synergistic effect: on the one hand, the atomically dispersed Mn/Co ions in the precursor form a heterojunction with a tight interface contact after sulfidation. The built-in electric field significantly accelerates charge transfer and enhances the pseudocapacitance contribution through the synergistic reaction of biredox pairs. On the other hand, the 3D multi-level pore channel structure inherited from MOF significantly increases the specific surface area and promotes the kinetics of electrolyte wetting and ion diffusion. Electrochemical tests show that in the three-electrode system, the material achieves a high specific capacitance, which is significantly better than the single-metal sulfide control group. This research lays a theoretical foundation for the development of energy storage devices with both high energy density and long lifespan through the synergistic mechanism of heterojunction interface engineering and pore structure regulation. Graphical The high energy density and power density of MOF-derived MnS@Co 1-x S bimetallic sulfides can meet high demand scenarios such as fast charging for electric vehicles and frequency regulation for smart grids. This work provides new ideas for the development of high-performance energy storage devices and the design of bimetallic sulfides electrode.

Obesity is not only a direct cause of health problems, but is also closely related to the incidence rate of a variety of noncommunicable diseases. Intervention for obesity requires high self-discipline and compliance from individuals, which often makes weight loss less smooth and prone to rebound. In this study, we prepared a dissolving microneedle (MN) loaded with compound traditional Chinese medicine (TCM). The base material was composed of a mixture of polyvinyl alcohol (PVA) and polyvinyl pyrrolidone (PVP), which met the requirements of solubility and sufficient mechanical properties. For the drug, we chose the Huatanqushi formula, which has a clear fat-reducing effect in clinical practice and is food and medicine homology. The results showed that the MN can penetrate the stratum corneum , rapidly release drugs in the dermis of the abdominal wall, alleviate the inflammatory state of local adipose tissue, regulate systemic lipid metabolism, and ultimately achieve weight loss. This MN patch is suitable for busy office workers to use conveniently, avoiding the discomfort of oral medication and the drawbacks of a large dosage and long medication time. It can effectively intervene in obesity with a minimal effect on the body. Graphical abstract

We demonstrate a strategy for the growth of Mn2+ ion doped cadmium based II–VI semiconductor quantum dots (QDs) with a designed buffer layer of ZnS (MnS/ZnS/CdS or Mn:CdS QDs), which aims to meet the challenge of obtaining highly efficient and well-resolved Mn2+ ion emission. First, small, high quality MnS cores are obtained by using thiols to replace conventional alkyl amines as capping ligands. Then a buffer layer of ZnS with a tailored thickness is introduced to the QDs before the growth of CdS shells to reduce the size mismatch between the Mn2+ (dopant) and Cd2+ (host) ions. The fabricated MnS/ZnS/CdS core/shell QDs exhibit a high PL QY of up to 68%, which is the highest ever reported for any type of Mn2+ ion doped cadmium based II–VI semiconductor QD. The photoluminescence (PL) of the QDs consists of well-resolved Mn2+ ion emission without any detectable emission from the CdS band edge or surface defects. In addition, our MnS/ZnS/CdS QDs cannot only be made water-soluble, but can also be coated by ligands with short carbon chain lengths, nearly without cost to the PL QY, which could make them strong candidates for practical applications in biology/biomedicine and opto/electronic devices.
