Stannous sulfide (SnS) with low-cost and high theoretical specific capacity possesses enormous potential in the application of lithium-ion batteries (LIBs). However, the sluggish Li ion diffusion kinetics and severe volume variation of SnS, result in inferior rate capability and poor cycling stability. Hollow SnS microflower spheres coated with N, S dual-doped carbon (H-SnS@NSC) are constructed through a facile hydrothermal reaction , polydopamine encapsulation and subsequent carbonization process. Such rational hollow structure is conducive to enhance the structural stability of the material. More importantly, N, S dual-doped carbon is synergistically coupled with SnS, which can greatly improve the electrons/ions kinetics and mitigate the volume expansion. As consequence, the H-SnS@NSC composite electrode exhibits an admirable specific capacity of 778.5 mAh g −1 at 0.5 A g −1 after 400 cycles. It still remains a specific capacity of 633.8 mAh g −1 after 800 cycles even at 1.0 A g −1 , corresponding to 81.7% of initial capacity. After being assembled into a full cell, the device delivers a stable capacity of 317 mAh g −1 at 0.1 A g −1 . This work manifests that morphology and structure engineering have bright prospects in promoting the practical applications for metal sulfides.

An excellent bioinspired, defect-engineered RPS–SnS₂ SERS was developed. • The method exhibited good linearity, low LOD, trueness and precision. • Selective detection of ACE and its plausible mechanism was investigated. • The ongoing residue monitoring for ACE in agricultural products is needed. Acetamiprid (ACE), a widely used neonicotinoid insecticide (NEO), poses potential health risks due to residue accumulation in fruits and vegetables. Herein, we report a SnS₂ microsphere semiconductor SERS substrate with abundant sulphur vacancies for rapid and highly sensitive ACE detection. The microspheres, formed via spontaneous self-assembly of nanosheets under solvothermal conditions, exhibit a rose-petal-like morphology (RPS–SnS₂) exploited as a bioinspired architecture for enhanced SERS performance. This hierarchical structure potentially facilitates molecular enrichment through capillary effects, while sulphur vacancies may promote charge transfer for SERS enhancement. Under optimised conditions, this method exhibits excellent linearity from 1.00 to 100 μg/kg, a low detection limit of ppb levels, and satisfactory recoveries (RSD < 3.44%). The substrate performance was validated in typical actual vegetables (Chinese cabbage, radish, broccoli, cauliflower, green onion) and fruits (apple and pear), demonstrating reliable, selective, and reproducible ACE detection. Comparison with LC-MS/MS showed no significant difference at the 95% confidence level. This bioinspired, sulphur-vacancy-rich SERS platform provides a validated approach for ACE screening in selected vegetable and fruit matrices, supporting further assessment of its broader applicability.

Multicolor photodetection, essential for applications in infrared imaging, environmental monitoring, and spectral analysis, is often limited by the narrow bandgaps of conventional materials, which struggle with speed, sensitivity, and room-temperature operation. We address these issues with a multicolor uncooled photodetector based on an asymmetric Au/SnS/Gr vertical heterojunction with inversion-symmetry breaking. This design utilizes the complementary bandgaps of SnS and graphene to enhance the efficiency of carriers' transport through consistently oriented built-in electric fields, achieving significant advancements in directional photoresponse. The device demonstrates highly sensitive photoelectric detection performance, such as a responsivity ( R ) of 55.4–89.7 A W –1 with rapid response times of approximately 104 μs, and exceptional detectivity ( D* ) of 2.38 × 10 10 Jones ~8.19 × 10 13 Jones from visible (520 nm) to infrared (2000 nm) light, making it suitable for applications demanding an imaging resolution of ~0.5 mm. Additionally, the comparative analysis reveals that the asymmetric vertical heterojunction outperforms its counterparts, exhibiting approximately 9-fold the photoresponse of symmetric vertical heterojunction and almost 100-fold that of symmetric horizontal heterojunction. This highly sensitive multicolor detector holds significant promise for applications in advanced versatile object detection and imaging recognition systems.

Although layered tin sulfide (SnS) nano-architectures are drawing much attention as anode materials in lithium ion batteries (LIBs) because of the high theoretical capacity, there are drawbacks such as the large volume expansion and low conductivity. To overcome these difficulties, attempts have been made to prepare tin sulfide/carbon (SnS/C) nano-hybrids by anchoring/coating nanostructured SnS on/in nano-sized carbon. However, the commonly reported SnS/C composites still suffer from initial Coulombic efficiency (ICE), high electrode swelling, and inferior long-term stability because of weak chemical affinity , and limited contacting interface between SnS and carbon specially at high SnS mass percentage. Herein, we report hierarchical micro-flowers self-assembled from SnS monolayers and nitrogen-doped graphene (NG) lamellar nanosheets (NG-SnS) which are suitable for LIBs anode. The NG-SnS with a high SnS mass percentage (93.9 wt%), obvious C–S bond, and increased contact provide to boost activity, utilization, conductivity, and reversibility of Li storage. Moreover, the elastic NG layers work as a mechanical supporter to decrease the outer volumetric expansion and restrain electrochemical agglomeration of SnS during (de)lithiation processes. The molecular engineered NG-SnS hybrid shows a high initial Coulombic efficiency of 88.2%, robust cycle stability with a high capacity of 790 mAh g −1 after 900 cycles at 0.5 C, considerable rate performance, and small electrode swelling of 12%.

The emergent two-dimensional (2D) material, tin diselenide (SnSe2), has garnered significant consideration for its potential in image capturing systems, optical communication, and optoelectronic memory. Nevertheless, SnSe2-based photodetection faces obstacles, including slow response speed and low normalized detectivity. In this work, photodetectors based on SnS/SnSe2 and SnSe/SnSe2 p−n heterostructures have been implemented through a polydimethylsiloxane (PDMS)−assisted transfer method. These photodetectors demonstrate broad-spectrum photoresponse within the 405 to 850 nm wavelength range. The photodetector based on the SnS/SnSe2 heterostructure exhibits a significant responsivity of 4.99 × 103 AW−1, normalized detectivity of 5.80 × 1012 cmHz1/2W−1, and fast response time of 3.13 ms, respectively, owing to the built-in electric field. Meanwhile, the highest values of responsivity, normalized detectivity, and response time for the photodetector based on the SnSe/SnSe2 heterostructure are 5.91 × 103 AW−1, 7.03 × 1012 cmHz1/2W−1, and 4.74 ms, respectively. And their photodetection performances transcend those of photodetectors based on individual SnSe2, SnS, SnSe, and other commonly used 2D materials. Our work has demonstrated an effective strategy to improve the performance of SnSe2-based photodetectors and paves the way for their future commercialization.

Ethnopharmacological relevance Ulcerative colitis (UC) is widely believed to be a leading risk factor of colorectal cancer . Gut microbiota is a known vital player in the progression of UC. Si–Ni-San (SNS) has been considered to effectively treat colitis in clinical practice during thousands of years, yet whether SNS ameliorated acute colitis mouse model by modulating intestinal flora has not been distinctly elucidated. Aim of the study Our study aimed to elucidate the effect of SNS against acute murine colitis and focused on the underlying mechanisms of SNS targeting gut microbiota . Materials and methods 16S RNA sequencing, molecular biological analysis, and fecal microbiota transplants (FMT) were conducted to reveal the mechanisms of SNS in regulating gut microbiota. Results In our study, SNS dramatically inhibited DSS-induced acute inflammatory responses by improving gut microbiota dysbiosis , as evidenced by decreased abundance proinflammatory species, upregulated abundance of anti-inflammatory species and potentially altered microbiota metabolite metabolism. Additionally, intestinal flora knockout and FMT experiments confirmed that the therapeutic effect of SNS on colitis was dependent on gut microbiota, and specifically on favoring the growth of potential probiotics , Akkermansia genus. Furthermore, we found that SNS alone and SNS combined with Akkermansia muciniphila ( A. muciniphila ) increased Mucin 2 (MUC2) production, thus enhancing the competitive edge of A. muciniphila among pathogenic gut microbiota. Conclusion Our study shed lights on the underlying mechanism of SNS in attenuating acute murine colitis from the perspective of intestinal flora and provides novel insights into the discovery of adjacent therapeutic strategy against colitis based on SNS and probiotics.

Background Metabolic associated fatty liver disease (MAFLD) is a chronic disease characterized by excessive lipid deposition in the liver without alcohol or other clear liver-damaging factors. AMP-activated protein kinase (AMPK)/silencing information regulator (SIRT)1 signaling pathway plays an important role in MAFLD development. Si-Ni-San (SNS), a traditional Chinese medicine, has shown reducing hepatic lipid deposition in MAFLD rats, however, the underlying mechanisms of SNS are barely understood.Purpose The aim of this research was to investigate the mechanisms of SNS in reducing hepatic lipid deposition in MAFLD rats by regulating AMPK/SIRT1 signaling pathways.Methods The components of SNS were determined by high performance liquid chromatography with mass spectrometry (HPLC-MS) analysis. MAFLD rats were induced by high-fat and high-cholesterol diet (HFHCD), and treated by SNS. SNS-containing serum and Compound C (AMPK inhibitor) were used to treat palmitic acid (PA)-induced HepG2 cells. To elucidate the potential mechanism, lipid synthesis-related proteins (SREBP-1c and FAS), fatty acid oxidation (PPARα and CPT-1), and AMPK/SIRT1 signaling pathway (p-AMPK and SIRT1) were assessed by Western blot.Results SNS improved serum lipid levels, liver function and reduced hepatic lipid deposition in MAFLD rats. SNS-containing serum reduced lipid deposition in PA-induced HepG2 cells. SNS could up-regulate protein expressions of PPARα, CPT-1, p-AMPK and SIRT1, and down-regulate protein expressions of SREBP-1c and FAS. Similar effects of SNS-containing serum were observed in PA-induced HepG2 cells. Meanwhile, Compound C weakened the therapeutic effects of SNS-containing serum on lipid deposition.Conclusion SNS could reduce hepatic lipid deposition by inhibiting lipid synthesis and promoting fatty acid oxidation, which might be related with activating the AMPK/SIRT1 signaling pathway. This study could provide a theoretical basis for the clinical use of SNS to treat MAFLD.

A novel La/O co-doped SnS oxysulfide catalyst (labeled SnLaOS) with heterovalent tin states and sulfur vacancy defects is successfully synthesized for effective catalytic reduction of toxic organics heavy metal ions with NaBH 4 in the dark. La/O co-doped and hydrogen peroxide-driven SnLaOS catalyst with suitable heterovalent Sn 2+ /Sn 4+ states and sulfur vacancy defects exhibited excellent catalytic reduction capability. The 100 mL 20 ppm of 4-nitrophenol (4-NP) and 50 ppm of rhodamine-B (RhB), methylene blue (MB), methyl orange (MO), and Cr(VI) solution are entirely reduced by 5 mg SnLaOS-3 within 10, 12, 12, 16, and 14 min, respectively, with durable stability. Synergistic transition metal La 3+ -cation and O 2− -anion co-doped SnS adjusted the energy bandgap and introduced sulfur vacancy defects, and the hydrogen peroxide-driven regulated the SnLaOS with suitable Sn 4+ /Sn 2+ states ratio. The sulfur vacancies in SnLaOS provide active sites for adsorbed proton for pollutants reduction, and heterovalent Sn 2+ /Sn 4+ states in SnLaOS facilitates electrons efficient transfer through electron hopping between Sn 2+ and Sn 4+ for pollutants reduction. This study provides a novel efficient catalyst for the water pollutants treatment.

The exploitation of high-performance anode materials is one of the key challenges for the development of lithium-ion batteries. Herein, we report a micro-nano structured (SnS–SnS2–S)/FLG (few-layer graphene) composite in which the in situ formed SnS, SnS2 and S nanoparticles are tightly supported by the in situ exfoliated FLG. The multi-phase structure could induce the formation of a high fraction of interfaces, enabling the interface-controlled lithiation/delithiation, which is characterized by large interfacial storage and fast interfacial diffusion, and boosting the electrode performance at high rates greatly. On the other hand, the step-wise lithiation/delithiation of S, SnS2 and SnS can offer nano-spatial confinement effects to accommodate the volume expansion and particle aggregation, and thus enhance the structural stability of the electrode. Meanwhile, the FLG matrix can serve as a robust layer to further maintain the structural integrity of the electrode. As an anode for lithium-ion batteries, the composite exhibits an ultrahigh gravimetric/volumetric capacity (1062.2 mA h g−1/2018 mA h cm−3 at 0.2 A g−1), ultrahigh rate (842/756 mA h g−1 even at 5.0/10.0 A g−1) and ultrastable cyclability (100%/93.6% capacity retention after 1000/2000 cycles at 1.0/10.0 A g−1). Even in full-cells and sodium-ion batteries, superb comprehensive performance is demonstrated. Therefore, the (SnS–SnS2–S)/FLG composite could be a new promising anode material for application in batteries.

Invasive bacterial infection interferes the normal orchestrated course of healing cascades during cutaneous regeneration. Hypoxia in the deep-seated infection microenvironment (IME) considerably precludes photonic disinfection efficacy, especially antibacterial photodynamic therapy (aPDT). Herein we develop IME-unlocked oxygen-evolving bio-catalytic fabrics composed of electrospun poly(ε-caprolactone) scaffolds, MXene/SnS 2 bio-heterojunctions (MX/SnS bio-HJs), and lactate oxidase (LOx) for deep-seated bacteria-infected cutaneous regeneration. LOx can deplete lactic acid produced by bacteria at infected site and yield hydrogen peroxide (H 2 O 2 ). The MX/SnS bio-HJs not only catalyze H 2 O 2 to produce hydroxyl radicals (·OH) through Fenton-like reaction, but also generate oxygen (O 2 ) to fortify aPDT under Near-infrared (NIR) light irradiation, consequently, expeditious disinfection is achieved. Moreover, in vivo results reveal that the bio-catalytic fabrics exert benign cutaneous regeneration ability by slaughtering bacteria, promoting hemostasis and collagen deposition. This work provides a tactic to instill fabrics with an IME-unlocked catalytic sterilization capability through endogenous O 2 evolution for remedying infected wounds.
