Superhydrophilic/submerged superoleophobic cotton fabrics with antibacterial properties were obtained by loading SiO 2 nanoparticles and Ag + on the surface of cotton fabrics through SiO 2 –Ag + composite sols, followed by the modification of the cotton fabrics with dopamine methacrylamide (DMA) and [2-(methacryloyloxy)ethyl]dimethyl-(3-sulfopropyl)ammonium hydroxide (SBMA). The surface morphology and wettability of the modified fabrics were characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), thermogravimetric/differential thermal analysis (TG), and contact angle measurement. The underwater contact angle and surface wettability analysis showed that the modified cotton fabric had an underwater oil contact angle of 166.5°. The prepared fabric can be used as an effective medium for the gravity-driven separation of oil/water mixtures. The modified fabrics showed resistance to sparing of vegetable oils or different organic solvents, and the average separation efficiency was better than 93% for all types of oil/water mixtures and up to 97%. In addition, the modified fabrics successfully inhibited the growth of Escherichia coli and Staphylococcus aureus with excellent antimicrobial properties.

Photocatalysis can directly convert solar energy into chemical energy, has shown unique advantages in solving environmental and energy problems. In this paper, novel UiO-66/p-BN (UBN) heterojunction photocatalysts were successfully prepared by a simple solvothermal method. UBN-6 achieved a degradation efficiency of up to 93.8 % for 30 mg/L tetracycline under 180 min of visible light irradiation, which was 2.46 and 3.25 times higher than that of pure UiO-66 and p-BN, respectively. The enhancement of UBN photocatalytic activity stemmed from the incorporation of p-BN, which increased the specific surface area to expose more active sites, broadened the visible light absorption range, and promoted the separation of photogenerated carriers through the formation of heterojunctions. Free radical trapping experiments showed that ·O 2 - , ·OH and h + played important roles in the photocatalytic degradation of tetracycline pollutants. In addition, the photocatalytic mechanism of UBN was revealed by analyzing the degradation intermediates of TC by LC-MS. This work provides an effective strategy for designing visible light responsive photocatalysts to degrade pollutants.

Inflammation is the main driver of the aggravation of arteriosclerosis, and the complex inflammatory response in plaque is usually the result of the interaction of various cells and cytokines. Therefore, it is difficult to comprehensively regulate the inflammatory process of arteriosclerosis by intervening a single target, resulting in the poor effect of existing treatment method. Based on our clinical findings that P-selectin stably and highly expressed in patients’ plaque endothelial cells, the programmed prodrug, low molecular weight heparin-indomethacin nanoparticles (LI NPs), were established as anti-inflammatory agent to multiphase inhibit arteriosclerosis by cascade interference of P-selectin. Structurally, LI NPs was obtained by simple esterification of low molecular weight heparin and indomethacin without any additives, guaranteeing the biocompatibility and applicability of LI NPs. Functionally, LI NPs could interfere with P-selectin in the inflammatory process, such as inhibiting macrophage adhesion, reducing the secretion of inflammatory factors, and inducing macrophage apoptosis. In the arteriosclerosis mice model, LI NPs significantly reduced the plaque area and showed satisfactory curative effect, which is related to the intervention of the multiphase inflammation between endothelial cells and macrophages. In conclusion, the programmed prodrug LI NPs offered a promising approach for the clinical therapy of arteriosclerosis.

Piezoelectric poly(vinylidene fluoride-trifluoroethylene) has demonstrated an ability to promote osteogenesis, and biomaterials with a chirality-patterned topological surface could enhance cellular osteogenic differentiation. In this work, we created a chirality-patterned surface potential distribution of CoFe2O4/poly(vinylidene fluoride-trifluoroethylene (CFO/P(VDF-TrFE)) membranes to explore their osteogenic response under no change in surface chemical and topology, attempting to further strengthen the ability of the membranes to promote osteogenesis. The chirality-patterned surface potential distribution was established by microdomain contact polarization with the help of sinistral/dextral-patterned ITO interdigital microelectrodes. In the in vitro evaluations, the mesenchymal stem cells showed a positive response in osteogenic differentiation to CFO/P(VDF-TrFE) membranes with both sinistral- and dextral-patterned surface potential distributions, however, the dextral-patterned distribution gave a stronger response than the sinistral-patterned one. And the in vivo evaluation showed a response tend in new bone tissue formation similar to the in vitro evaluations. The stronger response in osteogenic differentiation and osteogenesis for the CFO/P(VDF-TrFE) membrane with the dextral-patterned distributions may be attributed to that the intense interaction of the cells with the electrophysiological microenvironment appears due to a correspondingly higher expression of integrin α5β1, which significantly up-regulates the Arp2/3 complex expression, a crucial factor for cytoskeleton reorganization, possibly increases cytoskeleton contractility, and strengthens the transduction of the osteogenesis-related signaling cascade. This work proves that the chirality-patterns in surface potential distributions could provide an osteogenic response similar to a chirality-patterned topological surface.

Development of highly-efficient heterostructured photocatalysts capable of fully utilizing full solar spectrum has emerged as a focal point in photocatalytic H 2 evolution from water splitting. Herein, Mn 0.2 Cd 0.8 S/MoSe 2 composite was successfully constructed by attaching full-spectrum responsive MoSe 2 nanospheres on surface of Mn 0.2 Cd 0.8 S polyhedra via in-situ hydrothermal process. The optimal Mn 0.2 Cd 0.8 S/MoSe 2 -5wt% composite photocatalyst yielded the H 2 evolution rate of 34.31 mmol g –1 h –1 under full-spectrum light, significantly surpassing the activities obtained under near-infrared (NIR), ultraviolet (UV), visible (Vis), Vis-NIR and UV-Vis light alone. This outstanding property could be attributed to the synergetic effects of p−n heterojunction and photothermal effect, effectively accelerating interfacial charge transfer, elevating reaction system's temperature and expediting surface reaction, thereby promoting the photocatalytic reaction of Mn 0.2 Cd 0.8 S. This study offers a valuable perspective on utilizing MoSe 2 to construct an efficient photothermal-assisted photocatalysis system.

The electrodeposition of Ni–P–PTFE nanocomposites offers an effective approach to reduce mold–polymer interface adhesion and improve the replication of polymer micro features in injection molding. However, it is still challenging to fabricate Ni–P–PTFE nanocomposites with low internal stress and nanoscale surface roughness in electrolytes containing high PTFE concentrations. In this study, cetyltrimethylammonium bromide was introduced into the electrolytes to achieve a good dispersion of PTFE nanoparticles. Ni–P–PTFE nanocomposites with various compositions were successfully electrodeposited, and their tribological properties were analyzed. The electroformed Ni–P–PTFE nanocomposites with high PTFE and phosphorus contents showed a low surface roughness and surface energy compared to nickel electrodeposits. Ni–P–PTFE nanocomposites also exhibited a low coefficient of friction (COF) and wear loss when electroformed from an electrolyte containing 32 g/L phosphorus acid and 5 g/L PTFE nanoparticle. The COF of Ni–P–PTFE against stainless steel and poly(methyl methacrylate) was 0.2 and 0.12, respectively, representing a decrease of 80% and 85% compared to nickel electrodeposits. These enhancements in self-lubricating performances were primarily attributed to the low surface roughness and a shift in wear modes from adhesive wear to predominantly mild abrasive wear.

FeVO 4 is recognized as a potential photoelectrode material on account of its relatively narrow bandgap and suitable conduction and valence band positions. However, its photoelectrochemical water splitting performance remains unsatisfactory owing to rapid carrier recombination and poor charge transport capabilities. Herein, a novel p-n FeVO 4 /AgVO 3 heterostructure photoanode was developed by depositing p-type AgVO 3 nanowires onto n-type FeVO 4 nanoporous structures, boosting the PEC properties of the base material. The incorporated AgVO 3 nanostructures enhance light absorption in the visible spectrum, facilitate effective electron-hole separation through optimized interfacial charge transport pathways, and simultaneously extend the carrier lifetime. The built-in electric field in the p-n heterostructure promotes more effective separation and directional motion of photoinduced charge carriers. As a result, the transient photocurrent density of the FeVO 4 /AgVO 3 heterojunction photoanode reaches 0.22 mA cm −2 , which is 3.35 times that of bare FeVO 4 (0.06 mA cm −2 ). Notably, the incorporation of AgVO 3 nanowires significantly improves the photostability of the FeVO 4 photoanode. This work provides a feasible strategy from the perspective of interface engineering for designing high-performance FeVO 4 -based photoelectrodes to enhance photoconversion efficiency.

p -Cresol has been identified as a key odorant that is responsible for the characteristic flavor of fermented bamboo shoots. Although it is known to play a significant role in bamboo shoot fermentation, the microbial sources and biosynthetic pathways of p -cresol is still poorly characterized. The relationship between the microbiota and flavor profiles in fermented bamboo shoots was systematically investigated in this study via metagenomics and gas chromatography–mass spectrometry (GC–MS). The results demonstrated that Lactobacillus and Kazachstania represented the dominant microbial genera, with Lactobacillus acetotolerans identified as the most abundant bacterial species. Phenols and acids were identified as the primary flavor components, and p -cresol was found to be the dominant flavor compound. Correlation analysis was further found to reveal significant positive associations between specific microorganisms (e.g., L. acetotolerans ) and key flavor compounds (including p- cresol). The formation of the main characteristic flavors in fermented bamboo shoots was closely associated with carbohydrate and amino acid metabolism pathways. Tyrosine was first converted to 4-hydroxyphenylacetate via transamination, followed by subsequent decarboxylation to p -cresol catalyzed by the enzyme 4-hydroxyphenylacetate decarboxylase. This study provides insights into the microbial mechanisms underlying the formation of the stinky flavor in fermented bamboo shoots.

This report reveals that the hydrogen evolution activity of VS 2 can be effectively strengthened by inducing the surface charge redistribution of VS 2 via P non-metal doping. The XRD, TEM, GPA, EDS and XPS characterizations confirm that the P atoms are successfully doped into the VS 2 /CC matrix by substituting S atoms, resulting in lattice tensile strain and charge redistribution. The optimal P-doped VS 2 on carbon cloth (P-VS 2 /CC) exhibits a low overpotential of 274 mV at − 50 mA cm −2 and a small Tafel slope of 65.4 mV dec -1 , much lower than those of VS 2 /CC counterpart (622 mV and 120.1 mV dec −1 , respectively). Moreover, the P-VS 2 /CC delivers a long-term stability for 55 h without decay at 10 mA cm −2 , outperforming the VS 2 /CC. Density functional theory calculations suggest that P doping can induce the charge transfer from S and V to nearby P atoms, resulting in the decrease of hydrogen adsorption free energy at the S and V sites and the increase of total density of states at the Fermi level, thus far super hydrogen evolution activity. This work provides a hopeful new route for strengthening the HER activity of VS 2 , and offers a new perspective for developing advanced transition-metal chalcogenides electrocatalysts.

Gallium oxide (Ga 2 O 3 ) film exhibiting the solar-blind absorption cutoff characteristic holds considerable potential for application in UV photodetectors . The material defects in the device will introduce the recombination region for the photodetector, especially at the interface of the Ga₂O₃ heterojunction . The photogenerated carriers , generated within the Ga 2 O 3 film, will inevitably be influenced by these high recombination centers during their transportation. Avoiding or minimizing this region can improve the performance of the photodetector. The p-n junction, with its depletion region , generates an electric field that drives the carriers away from the recombination region. However, due to the Ga 2 O 3 p-type doping difficulty, our work focuses on the growth of single-crystal NiO/β-Ga₂O₃ films by Mist-CVD and the fabrication of field-controlled photodetectors. The hole concentration in the NiO film is adjusted by doping with different concentrations of Li⁺. Compared with a photodetector without the NiO interlayer, the performance of the photodetector with the structure of NiO (1 % Li⁺-doped)/β-Ga₂O₃ exhibits a significant improvement, which achieved the maximum responsivity of 1002.5 A/W, and a high peak detectivity of 3.31 × 10 15 Jones.

Intercalation pseudocapacitance is the key point to achieving the balance between the volumetric capacitance and the rate performance of energy storage. However, the low pseudocapacitive reactivity of the active center still limits the energy density of the pseudocapacitance devices. Herein, we propose a strategy that regulates the p - d hybridization of confined MXene via the co-doping of B and O atoms (BO-MXene) for outstanding electrochemical performance. Both experiments and density functional theory (DFT) reveal that the inner doped O atoms in low 2 p orbital energy strengthen the hybridization of Ti and electron-deficient B in MXene for high retention of B atoms, weaken the Ti-O covalency in MXene. As a result, the weakened p - d hybridization of Ti and O for the outer surface and strengthened p - d hybridization of Ti and B for the inner, promote the adsorption of protons and electron transfer, respectively. Further, the BO-MXene-based hybrid supercapacitors achieve a significant volumetric energy density of 56.86 Wh L -1 at 25.6 kW L -1 . This electronic structure via tuning the p - d hybridization in MXene proposes a new path for designing proton-confined intercalation pseudocapacitance.

Ammonia (NH3), the second most produced chemical in the world, is predominantly utilized in fertilizer production to underpin modern agriculture and has recently attracted interest as an energy-dense source of renewable energy. Herein, an amorphous CuTe porous nanonets (CuTe PNs) catalyst with p-d orbital hybridization was designed and prepared for NH3 synthesis via the nitrite reduction reaction. The porous and amorphous structure of CuTe PNs provides sufficient channels for molecular penetration and enhances active site accessibility through its abundant defects and vacancies, facilitating electrochemical reactions. The CuTe PNs exhibit excellent nitrite reduction reaction performance (NH3 yield: 633.7 μg h–1 mgcat–1, Faradaic efficiency: 91.41%, NH3 selectivity: 92.2%). This work describes a powerful pathway for the fabrication of p-d orbital hybrid amorphous porous nanonets catalysts and also provides a new possibility for the electrochemical synthesis of NH3.
