Reactive oxygen species (ROS) are highly prevalent in skin-related impairments and accelerate chronic ulcer progression. The routine subcutaneous administration approaches combining drug delivery with microenvironment intervention are widely developed for skin-related treatment but lack effective outcomes. Herein, we present a cuttlefish ink-derived nanoparticles (CNPs)-integrated microneedles patch, silk fibroin and cuttlefish ink-derived melanin nanoparticles (SC-MNs), that can easily be inserted into the skin and alleviate ROS. The microneedle tips, formed from silk fibroin and treated with methanol vapor annealing, turn to increased β-sheet and enhanced mechanical strength. Meanwhile, the tips can rapidly detach from SC-MNs in mildly acidic conditions due to the introduction of NaHCO 3 . SC-MNs also exhibited a unique ROS obliteration capacity. Furthermore, under near-infrared irradiation, SC-MNs triggered photothermal performance, which elicited reliable tumor cell-killing effects. Collectively, these SC-MN patches described here can provide a promising platform for combined ROS-scavenging and photothermal therapy, which makes them a potential candidate in skin-related disease management.

Replacing anodic oxygen evolution reaction with 3,5-diamino-1,2,4-triazole oxidative coupling enables ultra-low-voltage (0.96 V @10 mA cm − 2 ) dual-electrode H 2 production and simultaneous synthesis of energetic 5,5′-diamino-3,3′-azido-1H-1,2,4-triazole (DAAT), achieving 35.8% energy savings.
A Pt single-atom/nanoparticle hybrid on NiS 2 nanosheets (Pt s,n @NiS 2 @CC) exhibits exceptional alkaline hydrogen evolution reaction performance and stability via optimized H* adsorption.
Anodic DAAT formation proceeds via an OH*-mediated N–N coupling pathway, enabling stable (> 300 h @500 mA cm − 2 ), industrial-scale bipolar H 2 production coupled with green DAAT synthesis in an anion-exchange membrane water electrolyzer.

Fresh Ginkgo biloba seed kernels are nutritious but contain toxic ginkgotoxin (MPN) and its 5′-glucoside (MPNG), limiting their safe consumption. Existing detoxification methods mostly target powdered/homogenized kernels, which are unsuitable for whole-kernel food products. In this study, ultrasound-assisted, microwave-assisted, and static water bath methods were compared and evaluated for the removal of MPN and MPNG from fresh whole Ginkgo biloba seed kernels. Among the three methods, the static water bath method exhibited higher detoxification efficiency (i.e., higher removal rates of MPNG, MPN, and TMPN (the sum of MPN and MPNG)) while better maintaining the integrity of whole seed kernels. Under the selected conditions of the static water bath method (material-to-liquid ratio of 1:20, temperature of 60 °C, duration of 27 h), the removal of MPNG, MPN, and TMPN of ‘Da Fozhi’ variety reached 87.51 ± 1.62%, 91.73 ± 4.69% and 87.87 ± 1.14%, respectively. Additionally, under the same selected conditions, the TMPN removal rates in two other varieties (‘Fo Shou’ and ‘Da Maling’) reached 79.01 ± 3.10% and 70.57 ± 5.67%, respectively. The static water bath method is convenient and low-complexity, achieving a relatively satisfactory detoxification effect for whole Ginkgo biloba seed kernels. This method lays the foundation for the detoxification of Ginkgo biloba seed whole kernels and also provides low-toxic Ginkgo biloba seed whole kernel raw materials for the food processing industry.

Aqueous zinc-ion batteries (AZIBs) hold great promise for next-generation energy storage but face challenges such as Zn dendrite growth, side reactions, and limited performance at low temperatures. Here, we propose an electrolyte design strategy that reconstructs the hydrogen-bond network through the synergistic effect of glycerol (GL) and methylsulfonamide (MSA), enabling the formation of a (100)-oriented Zn anode. This design significantly broadens the operating current and temperature windows of AZIBs. As a result, Zn||Zn symmetric cells exhibit remarkable cycling stability, achieving 4,000 h at 1 mA cm −2 and 600 h at 40 mA cm −2 (both at 1 mAh cm −2 capacity); even at −20 °C, Zn||Zn symmetric cells deliver ultra-stable cycling for over 5,400 h. Furthermore, Zn||VO 2 full cells retain 77.3% of their capacity after 2,000 cycles at 30 °C with a current density of 0.5 A g −1 and 85.4% capacity retention after 2,000 cycles at −20 °C and 0.25 A g −1 . These results demonstrate a robust pathway for enhancing the practicality and low-temperature adaptability of AZIBs.

A novel Al 2 O 3 –PDA–MoS 2 nanohybrid was synthesized by depositing Al 2 O 3 nanoparticles on the surface of molybdenum disulfide (MoS 2 ) sheets covered with polydopamine (PDA). Many characterizations demonstrated that the Al 2 O 3 was successfully deposited on the surface of MoS 2 . It was found that when the mass ratio of PDA–MoS 2 to Al 2 O 3 was 1.5:1, the nano-hybrid filler showed good dispersion performance. Then, the composite coating samples were prepared by adding Al 2 O 3 –PDA–MoS 2 (1.5:1) hybrid to waterborne epoxy resin. The effects of Al 2 O 3 , MoS 2 , and PDA–MoS 2 on the corrosion resistance of epoxy coating were also investigated. The potentiodynamic polarization test demonstrated that Al 2 O 3 –PDA–MoS 2 nanohybrids had excellent corrosion inhibition properties. The results of electrochemical impedance spectroscopy also revealed that the impedance modulus of Al 2 O 3 –PDA–MoS 2 /EP composite coating was nearly two orders of magnitude higher than that of pure epoxy resin after immersion in saline for 21 days. This study confirmed that Al 2 O 3 –PDA–MoS 2 nanosheets had better barrier properties and corrosion inhibition properties, and provided a new idea for the wide application of nanofillers in the field of anticorrosion.

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.

To study the electrochemical properties of Yb-doped CaZrO 3 in more detail, the CaZr 1 −x Yb x O 3 −δ ( x = 0.000, 0.025, 0.050, 0.075, and 0.100) solid electrolyte specimens were prepared by high-temperature solid-state method at the temperatures of 1523 K and 1873 K for 8 h. XRD, SEM, EDS, and electrochemical workstation were used to test the micromorphology and electrochemical performance of the electrolyte samples. When the doping amount of Yb is 0.05, the electrolyte sample has excellent electrical properties. The total conductivity of electrolyte CaZr 0.95 Yb 0.5 O 3 − δ is 1.13 × 10 −5 to 1.28 × 10 −3 S/cm and the conductivity activation energy falls in 0.69–1.34 eV in hydrogen and oxygen atmosphere at 973–1173 K. The chemical diffusion coefficient of hydrogen in CaZr 0.95 Yb 0.05 O 3 −δ electrolyte is between 1.55 × 10 −6 and 5.82 × 10 −6 cm 2 /s in the temperature range of 973 to 1373 K, and the diffusion activation energy is 12,278 kJ/mol.

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.

In this investigation, MgO-doped BaTiO 3 (BT) ceramics were prepared by a conventional solid-state sintering method. Perovskite-structure was identified by an X-ray diffraction method. Relatively high volume density and relative density were achieved with appropriate MgO contents. With MgO doping, the temperature stability of the dielectric constant of BT samples was drastically improved when the temperature is below their Curie temperatures. It is very interesting that both the energy storage density and breakdown electric field are enhanced by MgO doping compared to that of undoped BT. Particularly, a high energy storage density ( W c ) of 0.9 J/cm 3 can be achieved at 130 kV/cm with a high energy storage efficiency ( η ) of 73.3% in 0.25 wt% MgO doped composition. The detailed investigation and analysis can be found in the study.

Co doped BaSnO 3 films [BaSn 1 − x Co x O 3 (0 ≤ x ≤ 0.50), i.e., BSCO] have been grown on MgO single-crystal substrates via pulsed laser deposition. Effects of the Co-doping level on the crystallinity, the microstructure, and optical properties of the BSCO films are investigated. All the BSCO films are of high crystallinity and grown epitaxially on MgO substrates. The lattice parameter of the (200) plane drops linearly with the increase of the ‘ x ’ value. The Co doping is found to increase the film roughness and the grain size, and a RMS roughness of 8.33 nm and grain size up to 100 nm are observed in the film with x = 0.50. The low Co-doping level ( x = 0.05, 0.1) has slight anti-reflection effects on the incident visible light, and the Co-doping level higher than 0.2 reduces the optical transmittance significantly. The optical bandgap shows a first-rising then falling trend with the increase of the Co content, and the lowest bandgap of 1.94 eV is realized in the BSCO film with x = 0.50.
