TiO2-based materials are important photocatalysts but the rapid recombination of photoexcited electron-hole pairs and the wide band gap both limit their photocatalytic activities. In this work, combining p-type phosphorus-doped graphene quantum dots (P-GQDs) and n-type silver iodide (AgI) with n-type TiO2, a novel ternary photocatalyst TiO2/P-GQDs/AgI with n-p-n heterojunctions was synthesized by a facile precipitation process. Morphologies, structures, optical properties, and chemical environments of photocatalysts were studied carefully. The ternary photocatalyst exhibited enhanced visible photocatalytic activity to degrade methyl orange (MO). TiO2/GQDs with an n-n single heterojunction, TiO2/P-GQDs with a p-n single heterojunction, and TiO2/GQDs/AgI(30%) with an n-n-n dual heterojunction, show 4.4-fold,5.3-fold and 14.2-fold of the bare TiO2. By contrast, the TiO2/P-GQDs/AgI (30%) with an n-p-n dual heterojunction has a more improvement show 70.4-fold of the bare TiO2. By electrochemical and optical measurement, the enhanced photocatalytic activity can be ascribed to promote the charge carrier separation by n-p-n heterojunctions and enhanced absorption in the visible region. Overall, the new band structure of two connected in series p-n heterojunctions looks promising as a highly efficient photodegradation system for future use to decontaminate polluted water. © 2022, The Authors.

The development of biodegradable and robust dielectric capacitors with high breakdown strength and energy density are indispensable. Herein, the high strength chitosan/edge hydroxylated boron nitride nanosheets (BNNSs-OH) dielectric film was fabricated via combining the dual chemically-physically crosslinking and the drafting orientation strategy, which could induced BNNSs–OH and chitosan crosslinked network alignment within the film via covalent and hydrogen bonding interaction, leading to the comprehensive reinforcement of tensile strength from 126 to 240 MPa, the E b from 448 to 584 MV m -1 , the in-plane thermal conductivities from 0.89 to 2.46 W m -1 K -1 and energy storage density from 7.22 to 13.71 J cm -1 , superior than the comprehensive evaluation of the reported polymer dielectrics. The dielectric film could be completely degraded in soil in 90 days, which opened a new path for the development of next-generation environment-friendly dielectrics with excellent mechanical and dielectric properties. © 2022, The Authors.

A novel electrochemical sensor for dopamine (DA) is developed based on heteroatom-doped carbon nanotubes derived from polypyrrole. X-ray diffraction, X-ray photoelectron spectroscopy, scanning electron microscopy, transmission electron microscopy, specific surface analyzer, and cyclic voltammetry are employed to characterize the microstructure and property of the products. The electrochemical catalytic activities of heteroatom-doped carbon nanotubes modified glassy carbon electrode (GCE) towards DA are further investigated by cyclic voltammetry, amperometry, and differential pulse voltammetry. The results indicate that heteroatom-doped carbon nanotubes prepared by pyrolysis of polypyrrole nanotubes at 800 oC possessed higher specific surface area and better electrochemical activity compared with others obtained at different temperatures. Therefore, the electrochemical sensor fabricated by the heteroatom-doped carbon nanotubes shows excellent detection ability towards DA as well as remarkable anti-interference ability and stability. These features collectively endow the polypyrrole-derived carbon nanotubes with a promising application for the fabrication of electrochemical sensors. © 2022, The Authors. All rights reserved.

Phase field simulation of liquid-solid-eutectoid multiple phase transformations of a Fe-C binary alloy

A new continuous multi-phase transformation field model was established for liquid-solid-eutectoid transformation. Taking Fe-C alloy as an example, the model was used to simulate the evolution of the micro-morphology of the liquid-solid phase transition, and the effects of temperature, solute and free energy on the nucleation of pearlite after the liquid-solid phase transition were analyzed. The micro-morphology of pearlite was simulated. The simulation results show that the austenite structure has hereditary effect on the pearlite, the morphology of pearlite structure was similar to that of the parent austenite. The eutectoid structure at the front of pearlite grows toward the interior of austenite grains in a bifurcation manner and in the spherical coronal shape. In addition, the growth rate of pearlite was related to the shape of concave-convex interface at the nucleation site, and the growth rate at the convex interface was faster than that at the concave interface.

Antimony selenide (Sb2Se3), a promising low-cost absorber material, is highly attractive in thin film solar cells due to its extraordinary optoelectronic properties. To replace commonly used expensive gold (Au) electrode, the electric properties between Sb2Se3 and aluminum (Al) interface are investigated in detail. We demonstrate that exposure to air generates a Schottky solar cell by formation of the oxides on Sb2Se3 surface and the device performance strongly depends on the oxidation thickness. An optimal PCE of 1.4% is achieved for the first time. X-ray photoelectron spectroscopy (XPS) measurements of the back surface reveal that the oxidation is consisted of amorphous Sb2O3, Se and SeOx. Conversely, the full vacuum device exhibits Ohmic behavior. Moreover, the removal of oxides results in a transition from Schottky to Ohmic contact. Our results indicate that the oxides play a crucial role at Sb2Se3/Al interface, which effects severely the transport of electrons. This study opens up an opportunity for fabricating low-cost high-performance Sb2Se3-based devices with alternative Al back contacts. © 2023, The Authors. All rights reserved.

This paper presents a new method for the efficient preparation of continuous carbon fibers reinforced SiC ceramic (Cf/SiC) composites using material extrusion (MEX) and reactive melting infiltration (RMI). A slurry with the ability to produce stable filaments with good surface quality has been obtained by comparing the rheological behavior. The resin impregnation-carbonization and RMI processes were used for densification to obtain Cf/SiC composites. The effect of the number of impregnation-carbonization on the properties and microstructure of the sintered bodies has been studied. When the impregnation-carbonization was used for 1 time, the specific strength of the sintered body reached the highest value of 4.5 [[EQUATION]] 10 4 N·m/kg and the bending strength reached 93.1±4.3 MPa. In addition, Cf/SiC with complex structures were prepared using this method. This new approach reveals significant potential for MEX printing technology to prepare Cf/SiC composites with complex and lightweight structures. © 2022, The Authors. All rights reserved.
