Crafting photoelectrocatalytic materials with robust oxidation-reduction properties for simultaneous hydrogen evolution and pollutant degradation poses a formidable challenge. In this study, a pg-C3N4/β-FeOOH S-scheme heterostructure with a special energy band structure was developed by anchoring porous pg-C3N4 on needle shaped β-FeOOH. Functioning as a hole extraction layer, needle-leaf-like β-FeOOH can facilitate efficient hole migration and enhance charge transport. Remarkably, the optimized 0.2-pg-C3N4/β-FeOOH could degrade 78% of ofloxacin (OFLO) in 90 min. The organic pollutants could absorb a large number of holes, which prompted a greater proportion of photogenerated electrons to actively participate in the hydrogen evolution reaction at the cathode. Consequently, the hydrogen production of 0.2-pg-C3N4/β-FeOOH reached 1452.88 µmol cm−2 h−1, exhibiting a notable increase of 61.81–165.12 µmol cm−2 h−1 compared with that in the absence of pollutants. Experimental and theoretical calculation results underscore that this investigation is grounded in a distinctive electron and hole dual channel transfer mechanism. These findings offer novel insights for the future development of S-scheme heterojunction photoelectrocatalytic materials capable of concurrently degrading pollutants and promoting hydrogen evolution.

The anticoagulant properties of materials are easily affected by the surface properties, which provide belief for designing and developing effective anticoagulant materials to achieve long‐term stable application of blood‐contacting implants and devices. Here, various nanocone‐shaped ZnO films were prepared by simple electrochemical deposition followed by hydrothermal method, and modified with polyethylene glycol (PEG10000, a hydrophilic substance). The influence of surface morphology and surface free energy on the anticoagulant properties of ZnO nanofilms was explored. Both hydrophilic (CA < 40°, surface modified with PEG10000) and superhydrophobic (CA > 150°, surface with rough needle‐like structure) ZnO nanofilms have good anticoagulant properties. Compared with the free energy of the film surface, the surface microstructure of ZnO nanofilms has a greater impact on the anticoagulant properties. After the ZnO nanofilms were modified with PEG, the contact model of water on the surface conforms to the Wenzel model instead of the Cassie model. The number of adhesive platelets was largely reduced, and the hemolysis rate is less than 5%, indicating the better blood compatibility. These characteristics are of special significance for the development of nanomaterials with good anticoagulation. [ABSTRACT FROM AUTHOR]

With the continuous development of bionics, such as, geckos and virginia creeper with both superhydrophobic and super‐adhesive, the surface wetting and super‐adhesive properties of various porous materials have attracted extensive attention of the scientific and medical communities. Here, the honeycomb polyurethane (PU) porous films with strong adhesion were successfully prepared by microphase separation method and the effects of growth parameters on their microstructure and adhesive strength to ice were investigated. It was found that a high relative humidity (e.g., 100%) and a low solution concentration (e.g., 2%) facilitated the formation of ordered honeycomb PU porous films, and as‐prepared PU pores with average pore diameter as small as 5 μm are better ordered and more uniform than these in related documents. Although the contact angle of water droplets on the surface of PU porous films increased from the premodification value of 85–130° to more than 160° after surface modification with polydopamine (PDA), the corresponding rolling angle remained approximately constant (180°), indicating that the surface of PU porous films has strong adhesion similar to geckos and virginia creeper. Furthermore, at lower temperature, the PU porous films exhibited the high adhesive strength of 142.13 kPa on ice, which was strongly dependent on the porous microstructures and surface compositions. The improved adhesive behavior to ice of honeycomb PU porous films modified with PDA provides new strategies for surface modification of materials and potential applications in medical domain.

In this work, sulfation effect on NH3-SCR performance over CeO2 with different morphology (nanocubes and nanorods) was carefully studied. A morphology-sensitive sulfation effect on NH3-SCR activity was observed on CeO2. Interestingly, the NO removal efficiencies of CeO2 nanocubes and CeO2 nanorods got greatly enhanced after the sulfation at low-temperature range (< 350 °C). CeO2 nanorods exhibited a much higher NH3-SCR activity than that of CeO2 cubes. However, compared to CeO2 nanocubes, CeO2 nanorods suffered from a severe deactivation when sulfated at higher temperatures (> 350 °C). A series of characterizations such as N2 adsorption–desorption, XRD, HR-TEM, TG–DTA, Raman and in situ DRIFTS of SO2 + O2 adsorption were conducted to investigate the interactions between SO2 and nano-shaped CeO2. It was revealed that the morphology of CeO2 nanorods was damaged severely when sulfated at high temperature (> 350 °C), while the structure of CeO2 nanocubes was relatively stable under the same condition. Furthermore, more sulfate species were found on CeO2 nanorods than on CeO2 nanocubes, in particular of bulk like sulfate species. As a result, the NO removal efficiency of CeO2 nanorods declined greatly when sulfated at high temperature. [ABSTRACT FROM AUTHOR]

Numerous studies have reported that long noncoding RNA (lncRNA) dysregulation is involved in the progression of many malignant tumors, including glioma. The lncRNA ZNFX1 antisense RNA 1 (ZFAS1) plays an oncogenic role in various malignant tumors, such as gastric cancer and hepatocellular carcinoma. However, the underlying molecular mechanism of ZFAS1 in glioma has not been fully clarified. In this study, we found that the expression of ZFAS1 was upregulated in both glioma tissues and cell lines. Functional experiments revealed that ZFAS1 promoted glioma proliferation, migration and invasion, and increased resistance to temozolomide in vitro. By using online databases, RNA pull‐down assays and luciferase reporter assays, ZFAS1 was demonstrated to act as a sponge of miR‐150‐5p. Furthermore, proteolipid protein 2 (PLP2) was shown to be the functional target of miR‐150‐5p. Rescue experiments revealed that ZFAS1 regulated the expression of PLP2 by sponging miR‐150‐5p. Finally, a xenograft tumor assay demonstrated that ZFAS1 promoted glioma growth in vivo. Our results showed that ZFAS1 promoted glioma malignant progression by regulating the miR‐150‐5p/PLP2 axis, which may provide a potential therapeutic target for the treatment of glioma.

Bimetallic AgPd nanoparticles have been synthesized before, but the interfacial electronic effects of AgPd on the photocatalytic performance have been investigated less. In this work, the results of hydrogen evolution suggest that the bimetallic AgPd/g‐C3N4 sample has superior activity to Ag/g‐C3N4 and Pd/g‐C3N4 photocatalysts. The UV/Vis diffuse reflectance spectroscopy, X‐ray photoelectron spectroscopy, CO adsorption diffuse reflectance FTIR spectroscopy, and FTIR results demonstrate that in the AgPd/g‐C3N4, the surface electronic structures of Pd and Ag are changed, which is beneficial for faster photogenerated electron transfer and greater H2O molecule adsorption. In situ ESR spectra suggest that, under visible light irradiation, there is more H2O dissociation to radical species on the AgPd/g‐C3N4 photocatalyst. Furthermore, DFT calculations confirm the interfacial electronic effects of AgPd/g‐C3N4, that is, Pdδ−⋅⋅⋅Agδ+, and the activation energy of H2O molecule dissociation on AgPd/g‐C3N4 is the lowest, which is the main contributor to the enhanced photocatalytic H2 evolution. Bimetallic photocatalysts: Bimetallic AgPd nanoparticles are loaded on g‐C3N4 for photocatalytic H2 evolution. The resultant AgPd/g‐C3N4 shows superior activity to the monometallic Ag/g‐C3N4 and Pd/g‐C3N4. The interfacial interaction between the metals is beneficial in accelerating photogenerated electron transfer, H2O molecule adsorption, and H2O dissociation, leading to enhanced photocatalytic H2O reduction to H2.
