The renewable energy powered electrochemical CO 2 reduction (ECO 2 R) to the value-added chemicals is not only conducive to store intermittent renewable energy but also to reduce CO 2 emission, leading to a carbon neutral society. Herein, novel SnO nanodisks have been developed for highly selective formate production by ECO 2 R. The Faraday efficiencies of formate on SnO nanodisks all exceed 90% with the partial current density of formate ranging from 9.0 to 300.4 mA cm -2 , which is one of the widest potential range for highly selective formate production. In addition, the energy efficiency of formate production reaches 61% in a gas diffusion full cell. Electrochemical tests indicate that the morphology and the electronic structure of SnO nanodisks both contribute to the weakening of the binding of *CO 2 − intermediate. The density functional theory simulations indicate that the Sn 2+ sites weaken the binding of *OCHO intermediate than Sn 0 and Sn 4+ sites. The decreased binding property of *CO 2 − and *OCHO intermediates on SnO nanodisks promotes their protonation and the desorption of formate, thus reducing the overpotential for formate production and boosting the kinetics for ECO 2 R.

Nitric oxide (NO) and S-nitrosothiol (SNO) are signal molecules and the products of nitrogen metabolism. Nitrate (NO 3 − ) is the main nitrogen source, and nitrate transporters (NRTs) are responsible for NO 3 − absorption or transport. However, the interactive effect between NO 3 − /NRT and NO/SNO in tree plants remains ambiguous. In the present study, 25 mmol L −1 NO 3 − and 1 mmol L −1 NO donor sodium nitroprusside (SNP) treatment that was conducted for 24 h enhanced NO/SNO and NO 3 − metabolism, whereas 2.5 mmol L −1 NO 3 − and 80 μmol L −1 N6022 (a compound that increases SNO content) treatment reduced them in seedling leaves of Fraxinus mandshurica and Betula platyphylla . Among the nine NRT family members examined, the gene expression level of NRT2.1 had a greater response to NO/SNO and NO 3 − treatment in the seedling leaves of F. mandshurica and B. platyphylla . Meanwhile, FmNRT2.1 mediated NO and SNO production in seedling leaves of F. mandshurica using Agrobacterium -mediated transient transformation. These findings shed light on the reciprocal regulation between NO 3 − and NO/SNO in seedlings of F. mandshurica and B. platyphylla , and NRT2.1 may act as a key regulatory hub.

Large capacity, high rate, and long-term cycling stabilities have always been pursued by lithium-ion batteries (LIBs). In this work, the straightforward hydrothermal and high-speed ball milling programs were employed to create the SnO 2 -NiO-C anode material. NiO nanoparticles with unique hexagonal crystal structure are an ideal choice for ion cycling and embedding, which can stabilize the structure and prevent SnO 2 from becoming coarser. The graphite encapsulated in the outer layer can effectively prevent volume expansion during the cycling as well. From the research results, SnO 2 -NiO-C exhibits a significant reversible capacity of 1224.3 mAh g −1 after 300 cycles at 0.2 A g −1 , and after the fourth cycle, the coulombic efficiency remains above 97%. And it also possesses a long-term cycling stability of 820.1 mAh g −1 after 1000 cycles at 1.0 A g −1 . Also, a significant rate property can reach 507.1 mAh g −1 even at 5.0 A g −1 . Therefore, the SnO 2 -NiO-C anode material for LIBs is promising because of its excellent electrochemical performance.

The severe non-radiative recombination loss caused by SnO 2 /perovskite interface defects greatly hinders the further improvement of the performance and stability of flexible perovskite solar cells (PSCs). Herein, a series of halides KM (M = F, Cl, Br, I) were inserted as interface layers to modulate the SnO 2 /perovskite interface. Both experimental and theoretical calculation demonstrated that F − exhibited stronger interface coupling effect between the SnO 2 and perovskite than other halide ions (Cl − , Br − , I − ). The F − had unique effects in effectively depressing SnO 2 /perovskite interface defects ascribed to the simultaneous formation of Sn F bonds and hydrogen bonds , resulting in reduced non-radiative recombination and improved interfacial contact. In consequence, the champion KF-modified flexible and rigid PSCs delivered outstanding PCE of 18.16 % and 21.36 %, accompanied by the enhanced V OC of 1.14 V and 1.16 V, respectively. Meanwhile, the stability of flexible PSCs was significantly ameliorated after KF modification, and about 84 % of the original efficiency could be retained even after 3000 bending cycles. This work provides a facile and efficient strategy for interface modulation to achieve high-performance and stable flexible PSCs.

Electrodeposition of Sn within porous anodic aluminum oxide (AAO) template was used to synthesize Sn nanowires. Ag seed layer was sputtered upon AAO template firstly, then the Sn nanowires were electroplated upon the seed layer. After electrodeposition the Ag seed layer was removed and the AAO template was dissolved in order to obtain Sn nanowires finally. The diameter of Sn nanowires was about 200 nm, being consistent with the template pore size, while the length of nanowires had a linear growth rate of approximately 2.49 μm/min. X-ray diffraction (XRD) and electron diffraction revealed that individual Sn nanowire was single crystal without preferential growth direction. The surface of the nanowire was wrapped by a thin SnO film (~5 nm thick), as verified by transmission electron microscopy (TEM) observation and X-ray photoelectron spectrometer (XPS) analyses. The synthesized Sn nanowire powders had a dark brown color, which comes from the surface SnO layer. Through the differential scanning calorimetry (DSC) analysis, the melting point of Sn nanowires was determined as 231.73 °C, which is about 2.7% lower than the pure Sn particles. Fabrication of Sn nanosolders from Sn nanowires was tried using liquid bath melting method. It was found that Sn nanowires could convert into spheroidal nanosolder in liquid paraffin, which demonstrated a novel technology to fabricate nanosolders used for nanoscale interconnections.

To develop high-performance non-precious metal-based electrocatalysts for oxygen reduction reaction (ORR) is an urgent demand. We herein report an ingenious strategy to develop highly selective and competitive precious metal-free ORR electrocatalyst Co/CoO/SnO encapsulated in N-rich mesoporous carbon (CCS@NPC) nanocubes, via a simple one-step introduction of all functional components. Atomically mixed composites with significantly enhanced catalytic activity were obtained by adopting amorphous mesoporous ternary metal oxides CoSnO 3 nanocubes as precursor and template. The synergistic effect of the triphase nanohybrids (Co, CoO & SnO) anchored in nitrogen-doped mesoporous carbon nanocubes promoted the catalytic reactions , owning to the anisotropic morphology, great heterojunction interfaces, and structural stability. The large-scale prepared CCS@NPC exhibited excellent electrocatalytic activity toward ORR with an admirable onset potential (1.01 V) and diffusion-limited current density (5.88 mA cm −2 ). The CCS@NPC showed stronger stability (20 h) and higher methanol tolerance with the concentration up to 8.0 M, compared to that of commercial Pt/C.

A highly flexible lignin-based carbon nanofibrous membrane functionalized with SnO 2 /BiOBr core-shell heterostructure (CNFs@SnO 2 /BiOBr) was fabricated via coaxial electrospinning and solvothermal synthesis. By positioning the SnO 2 precursor in the shell layer during electrospinning, rapid and stable stabilization of the lignin nanofiber at a rate of 1°C/min was achieved, significantly reducing the high-energy consumption constraints of traditional preparation processes. Experimental results demonstrated that the CNFs not only enhance light absorption capacity and promote electron transfer but also effectively suppress the recombination of electron-hole pairs at the SnO 2 /BiOBr heterojunction, thereby improving charge separation efficiency. Under LED light irradiation, the CNFs@SnO 2 /BiOBr membrane exhibited a degradation efficiency of 87.3% for Rhodamine B within 100 min with optimal performance at natural pH (6.2), increasing to 93.0% at pH 3.5. Additionally, the composite membrane maintained a stable efficiency of 84.5% after five cycles at pH 6.2, owing to its outstanding photocatalytic performance and self-supporting structure (tensile strength of 0.601 MPa and elongation at break of 6.10%). This research offers a sustainable approach to designing flexible photocatalytic membranes for wastewater treatment, emphasizing environmental and green significance while enhancing biomass resource efficiency. By improving heterojunction catalytic efficiency and addressing the challenge of recovering traditional powders, it demonstrates promising applications in advancing sustainable wastewater treatment solutions.

Periodontal disease is one of the most common oral infectious diseases and closely related to many systemic diseases which is in urgent need of novel and effective drugs. In particular, the problems of deep lesion location and synchronization of antibacterial and anti-inflammatory needs to be addressed. Herein, near infrared (NIR) light triggered nanoplatform with antibacterial and anti-inflammatory dual-functions by antibacterial photodynamic therapy (aPDT), photothermal therapy (PTT) and gas therapy was realized by loading S-nitrosothiols (SNO) and ICG into mesoporous silica-coated gold nanorods . Using a single 808 nm NIR light, the excellent antibacterial efficacy can be achieved not only by aPDT-induced bacteria killing but also by PTT-triggered biofilm dispersal. Furthermore, SNO molecules would also be thermally activated to release nitric oxide (NO) gas molecules at the site of periodontal disease, exerting inflammation inhibition by suppressing the assembly of pro-inflammatory factors and NLRP3 inflammasome. Additionally, such nanoplatform could validly combat pathogenic bacterial biofilm, and modulate the inflammatory immunity, leading to favorable therapeutics on animal models with periodontal diseases. Hence, this design provides an effective solution to solve the problems of deep tissue treatment along with simultaneously antibacterial/anti-inflammatory capabilities, which provides a bright prospect for clinical treatment of periodontal diseases, even extended to other refractory infections in deep sites.
