Modulating hot carrier dynamics is crucial in tin halide perovskite photovoltaics, particularly under indoor illumination with limited photon flux. Herein, a fullerene derivative bearing four piperazine groups (denoted as TPPC) is synthesized to engineer the perovskite/C 60 interface. The TPPC molecule exhibits a dipole moment of 1.97 Debye, leading to enhanced adsorption energy on perovskite surface and robust interfacial interaction. The newly formed surface dipole optimizes the interfacial energy level alignment via a cascade gradient, enabling modulation of interfacial hot carrier dynamics. Consequently, TPPC-treated photovoltaic devices achieve a champion power conversion efficiency (PCE) of 22.49% and a maximum output power density ( P out ) of 64.1 μW cm -2 under white light-emitting diode illumination (3000 K, 1000 lux, 285 μW cm -2 ). Large-area (1.21 cm 2 ) devices attain a PCE of 17.94% (certified: 15.93%) and a maximum P out of 51.2 μW cm -2 under the same illumination conditions.

Thermoelectric (TE) materials, owing to their capability of direct heat-to-electricity interconversions, hold great potential in constructing smart buildings. However, reports on their integration into smart buildings remain scarce. In this work, we prepared biobased composite TE films. Their excellent photothermal conversion capability facilitates efficient absorption of solar energy and conversion into heat, establishing a large and stable temperature gradient, thereby synergistically achieving higher TE performance. Inspired by the unique overlapping and interlocking design of tiles in typical Chinese and oriental ancient architectures, where the curved tile surface enhances solar capture and the formed porous structures ensures efficient heat sink, we ingeniously designed and fabricated tile-shaped TE devices. Benefiting from the film’s photothermal effect, the prepared devices achieve a large temperature difference of nearly 60 K under solar irradiation. A device consisting of 20 TE legs generates an output voltage of 60 mV and a maximum output power of 11.9 µW, demonstrating excellent building-integrated TE energy harvesting performance. Furthermore, the TE system exhibits rapid fire warning capability, thereby providing fire protection for buildings. This work not only opens a novel avenue for achieving simultaneous harvesting of solar energy and self-powered fire warning, but also provides pioneering insights into green smart buildings and the protection of ancient architectures and cultural relics.

A ternary Z-scheme heterojunction photocatalyst, BiOBr/TiO 2 /NH 2 -UiO-66(Zr), was constructed to enhance the visible-light-driven degradation of tetracycline (TC). This composite material was synthesized via hydrothermal and in situ growth methods, and its microstructure and properties were analyzed through a series of systematic characterizations. The introduction of NH 2 -UiO-66 significantly increased the specific surface area and visible light absorption while promoting the separation and transport of photogenerated charge carriers. Under visible light irradiation, the optimal composite (BTU-2) achieved a TC degradation rate of 96.3% within 80 min, with a reaction rate constant 9.41, 12.03, and 8.58 times higher than those of pure BiOBr, TiO 2 nanowires (NWs), and NH 2 -UiO-66, respectively. Trapping experiments and electron paramagnetic resonance (EPR) analysis confirmed that h + and ‧O 2 − were the dominant active species. Liquid chromatography–mass spectrometry (LC–MS) further elucidated the possible TC degradation pathways. This work provides a feasible strategy for designing efficient visible-light-responsive photocatalysts for antibiotic wastewater treatment. Graphical abstract

Bottom-up construction of artificial cells helps elucidate the working mechanism of cells. Signal transduction from extracellular to intracellular artificial cells is essential for autonomous artificial cells. It remains highly challenging to reconstitute G protein-coupled receptor (GPCR) signaling pathways to regulate downstream metabolism in artificial cells. Here, we reconstitute β2-adrenergic receptor, Gs subunit α and adenylate cyclase V into artificial cell membranes to enable signal transduction from extracellular isoproterenol (ISO) to intracellular cAMP (visualization via Epac1-cAMP probes). cAMP production is ISO dose-dependent, with a maximum amplification fold of 22.45 ± 2.14. By encapsulating the glycogenolytic pathway, cAMP activates protein kinase A, triggering phosphorylation of phosphorylase kinase and glycogen phosphorylase to convert glycogen to glucose-1-phosphate (G-1-P). G-1-P is further converted to 6-phosphogluconolactone accompanying with NADPH. ISO stimulation induces G-1-P and NADPH generation, achieving progressive signal amplification. The successful reconstitution of GPCR-mediated signaling pathway in artificial cells paves the way for developing autonomous artificial cells.

Magnetic loss is a key factor limiting the application of nanocrystalline soft magnetic composite materials (n-SMCs) in high-frequency environments, and insulative coating and annealing treatment are important methods to reduce magnetic loss. In this study, a nano-La₂O₃ insulative coating was applied to the surface of FeSiBNbCu nanocrystalline magnetic powder via physical grinding combined with ultrasonic vibration. The effects of nano-La₂O₃ coating content (0–1 wt%) and annealing temperature (455–530 ℃) on the soft magnetic properties of the magnetic powder core were systematically investigated. The results showed that the nano-La₂O₃ coating could significantly improve the insulative performance between magnetic powders and effectively reduce the P e of n-SMCs. With the increase of nano-La₂O₃ content, the P e showed a trend of first decreasing and then increasing, reaching the lowest at 0.75 wt%. The P e decreases from 193.43 mW/cm 3 (with 0.0 wt% La₂O₃) to 142.537 mW/cm 3 (with 0.75 wt% La₂O₃ at f = 1 MHz), representing a reduction of 26.3%. Meanwhile, by optimizing the annealing process, the residual internal stress in the magnetic powder core induced during compaction is effectively relieved, leading to a significant decrease in hysteresis loss. As the annealing temperature increases, the hysteresis loss of the magnetic powder core reaches its minimum at 505 °C. When the nano-La₂O₃ content was 0.75 wt% and the annealing temperature was 505 ℃, the prepared nanocrystalline magnetic powder core exhibited optimal soft magnetic properties: a stable effective permeability (22.47) and the lowest total loss (230.4 mW/cm 3 at f = 1 MHz, B m = 20 mT), which was 22.89% lower than that of the untreated sample. This study provides a new process scheme for the development of high-performance low-loss n-SMCs.

Hierarchical zeolites can provide multidimensional spatial networks, thereby holding significant potential as catalysts for BTX production from biomass pyrolysis. In this study, nano-ZSM-5 zeolite (Z X-X ) with a hierarchical pore structure was synthesized using glycine as a growth inhibitor. Due to the exceptional ability of Ni to cleave C–C and C–H bonds, Ni modification was performed on the Z 30-0.2 catalyst. The effects of glycine and Ni loading on the morphology and pore structure of the zeolites were systematically investigated using scanning electron microscopy (SEM), transmission electron microscopy (TEM), and N 2 adsorption–desorption. The results demonstrated that the particle size of 10 wt% Ni-Z 30-0.2 zeolite ranged from 200 to 300 nm, with a BET surface area of 314 m 2 /g and abundant mesopores. The NH 3 -TPD results showed that the acid amount of 10 wt% Ni-Z 30-0.2 was 0.72 mmol/g. The prepared zeolite was employed in a fixed-bed reactor to catalyze the pyrolysis of oleic acid for the production of benzene, toluene, and xylene (BTX). The introduction of metal Ni significantly enhanced the BTX yield. At 500 ℃, the average BTX yield achieved with the 10 wt% Ni-Z 30-0.2 catalyst was 19.4 wt%, which was higher than that of the zeolite without Ni loading.

Background Obesity, characterized by lipid accumulation, oxidative stress, and inflammation, remains a major public health challenge. This study aimed to investigate the therapeutic efficacy of diosgenin-loaded silver nanoparticles (Dio-AgNPs) in modulating obesity-induced metabolic and molecular dysfunction through integrated biochemical, gene expression, and molecular docking approaches. Methods Male albino rats were randomly assigned to control and experimental groups, with Dio-AgNPs administered at two distinct doses. Dio-AgNPs were synthesized and characterized using UV-Vis spectroscopy, TEM, DLS, and zeta potential measurements to confirm particle size and stability. Biochemical analyses included serum lipid profile (triglycerides, total cholesterol, LDL-c, HDL-c), fasting glucose, insulin levels, and HOMA-IR for insulin sensitivity. Oxidative stress markers (MDA) and antioxidant enzymes (SOD, CAT, GPx) were measured spectrophotometrically. Inflammatory cytokines (TNF-α and IL-6) were quantified by ELISA. Gene expression of lipogenic enzymes ( ACC and FAS ) and antioxidant-related genes was assessed using quantitative real-time PCR (qRT-PCR). Molecular docking simulations were performed to evaluate diosgenin’s binding affinities and interactions with ACC and FAS enzyme active sites. Results Dio-AgNP-treated rats showed significant reductions in serum triglycerides, total cholesterol, LDL-c, and fasting glucose compared to controls, while HDL-c and insulin sensitivity were markedly improved. Antioxidant enzyme activities (SOD, CAT, GPx) increased significantly, and MDA levels decreased, indicating oxidative stress attenuation. ELISA confirmed reduced levels of TNF-α and IL-6, revealing anti-inflammatory effects. Gene expression analysis demonstrated dose-dependent downregulation of ACC and FAS , along with upregulation of antioxidant and insulin-responsive genes. Molecular docking results revealed strong binding interactions of diosgenin with both ACC and FAS enzymes, supporting enzymatic inhibition and the transcriptional trends observed. Silver nanoparticle delivery enhanced bioavailability and target specificity. Conclusion This is the first report, to our knowledge, that combines biochemical, gene expression, and molecular docking data to investigate Dio-AgNPs’ anti-obesity effects. The findings highlight a promising nanomedicine-based approach for metabolic regulation and pave the way for further research in therapeutic nanoparticle design and application.

A novel N -halamine precursor with tertiary amino group (5,5-dimethylhydantoinyl-3-ylethyl)-dimethylamine (DEADH), was synthesized and then covalently bonded onto cotton fabrics modified by 3-chloropropyltrimethoxysilane to form quaternarized N -halamine precursor grafted cotton fabrics which could be transferred to N -halamine structure upon exposure to dilute sodium hypochlorite solution. The grafted cotton fabrics were characterized by FT-IR, X-ray photoelectron spectroscopy, and field emission scanning electron microscope. The antimicrobial test showed that the cotton fabrics grafted with the quaternarized N -halamine were capable of 7-log inactivation of Staphylococcus aureus and Escherichia coli O157:H7 within 1 min of contact time. Very interestingly, it was found that the grafting process and following chlorination had almost no adverse effect on the tensile strength of cotton fabrics. Furthermore, the antimicrobial cotton fabrics exhibited good washing durability and stability.

With high capacity and low redox potential, Sn-based materials represent promising anodes for sodium-ion batteries (SIBs). However, the large volume expansion during the cycling process limits their application. Herein, we report a cost-effective, simple, and non-toxic SbSn/SP@C electrode for SIBs via ball milling process and sucrose reduction method. The SbSn/SP@C electrode exhibits high cycle stability and good reversible capacity for SIBs (400.3 mAh g −1 after 100 cycles). Consequently, SbSn/SP@C electrode can afford an effectively carbon-based conductive system, which buffers large volume change of SnSb alloy during the cycling process and provides promising electrochemical performance in Na storage.

In this study, hydrochloric acid solution concentration-controlled micro/nanostructured mixed crystalline phase of TiO 2 coated with graphene was prepared via a one-step hydrothermal method to improve photocatalytic degradation of organic pollutants. By several characterization methods such as X-ray diffraction, scanning electron microscopy, transmission electron microscopy, we demonstrate that the mixed crystal phase of TiO 2 (2–5 nm) evenly distributed among the thin graphene layers when the concentration of hydrochloric acid solution is 3 mol/L. Compared with the bare P25, the photocatalytic activity and adsorption capacity of the composites were much enhanced, resulting from the involving of graphene sheet as chainmail, which facilitates the charge separation, suppresses the recombination of electron–hole pairs, and improves light conversion efficiency of catalysts. In addition, the degradation rate of micro/nanostructured TiO 2 /GN (graphene) composite under ultraviolet light irradiation was much higher than pure TiO 2 . After 40 min irradiation, the degradation rate of RhB reaches 97.2%. It is expected that this synthetic strategy may provide a new pathway for the fabrication of various GN-based hybrids with multi-dimensional micro/nanostructures.

The microstructure of bituminous coal can be changed significantly due to injection of CO 2 foam fracturing fluid into the coal seam, affecting CBM production efficiency. To investigate the microstructural change characteristics of bituminous coal treated with high-pressure CO 2 foam fracturing fluid at different treatment times (0–24 h), medium-rank bituminous coal was selected as the research object. X-ray diffraction, Fourier transform infrared spectroscopy, and low-temperature N 2 adsorption tests were carried out to study the changes in mineral components, functional groups, micropore structure, respectively. It was found that the pore structure of bituminous coal can be changed by CO 2 foam fracturing fluid. With increase in modification time, the proportion of macropore (> 50 nm) volume of bituminous coal increased gradually, while the proportion of pore (2–5 nm) volume showed a trend of “increase rapidly–decrease rapidly–decrease slowly.” When the modification time was within 6–24 h, the average pore size showed a quadratic polynomial positive correlation with treatment time, the seepage pore fractal dimension ( D 1 ) decreased linearly with increase in modification time, and the adsorption pore fractal dimension ( D 2 ) showed the opposite trend. Moreover, with increase in modification time, the infrared peak area of oxygen-containing functional groups and aromatic, aliphatic, and hydroxyl structures of bituminous coal showed a trend of “decrease rapidly–decrease slowly,” the aromaticity and degree of aromatic ring condensation showed “decreasing–increasing–decreasing” trends, and the aliphatic chain length and oxygen-containing functional groups fluctuated and increased. CO 2 foam fracturing fluids significantly dissolve clay and carbonate minerals in bituminous coal. Coal microstructure can be changed by CO 2 foam fracturing fluid through hydrocarbon extraction and transport, differential swelling, and mineral dissolution. The findings showed that 18–24 h was the optimal time range for fracturing fluid flowback after performing CO 2 foam fracturing measurements. The research results are significant for selecting CO 2 foam fracturing fluid flowback time and improving CBM recovery.
