Abstract Ternesite (4CaO·2SiO₂·CaSO₄)-Ye’elimite (3CaO·3Al₂O₃·CaSO₄) (simplified as TY) cement clinker was successfully prepared from steel slag at 1200°C in this study. XRD, TG/DSC and SEM were used to analyze the mineral composition and hydration products of the TY clinker. The sintering process and hydration mechanism of the TY clinker were investigated. Results show that a large amount of ternesite and ye’elimite have been formed at 1200°C, while ternesite has not been decomposed. Clinker minerals include ternesite, ye’elimite, gypsum and a small amount of iron phase. Iron phase from steel slag can promote the formation of liquid phase with the presence of gypsum… More >

Abstract CoSbS-based compounds are good thermoelectric materials with low thermal conductivity and good electrical properties, which can effectively be used to improve the efficiency of many thermoelectric conversion processes. In order to improve their properties even more, in this study a series of experiments have been conducted in the frame of the traditional solid-phase synthesis and high-pressure method. It is shown that if the mass fluctuation and stress fluctuation in the considered CoSbS system increase, the scattering probability of phonons is enhanced and the lattice thermal conductivity of the material is reduced. Adding a small amount of Se can simultaneously optimize… More >

Abstract As an innovative theory and technology, quantum network coding has become the research hotspot in quantum network communications. In this paper, a quantum remote state preparation scheme based on quantum network coding is proposed. Comparing with the general quantum remote state preparation schemes, our proposed scheme brings an arbitrary unknown quantum state finally prepared remotely through the quantum network, by designing the appropriate encoding and decoding steps for quantum network coding. What is worth mentioning, from the network model, this scheme is built on the quantum k-pair network which is the expansion of the typical bottleneck network—butterfly network. Accordingly, it… More >

Abstract The NAC (NAM, ATAF, and CUC) superfamily is one of the largest plant-specific families containing transcription factors. An increasing number of studies suggest that NAC1 is involved in plants response to different biotic and abiotic stimulis. Nicotiana benthamiana is a widely used system for evaluating plant-pathogen interactions. In order to study the biochemical function of NbNAC1, NbNAC1 protein and antibody are essential. Therefore, we focused on developing a prokaryotic expression system for producing the Nicotiana benthamiana NbNAC1 protein of in Escherichia coli and the preparation of its polyclonal antibody. Firstly, we constructed two different molecular weight prokaryotic expression vectors: pGE… More >

Abstract A cellular material in the form of 3-layered sandwich structure material was prepared via sole use of mechanical stirring without any use of a foaming agent, while Tween-80 was employed as a foam stabilizer via a developed in-situ mold casting. The resulting structure displayed a good appearance with no visual defects. The 3-layered composition of the sandwish structure, “nonporous resin layer-porous foam layer-nonporous resin layer”, was examined in terms of the microstructure, density & density distribution, pulverization ratio, mechanical strength, insulation and flame retardant performance. It was indicated from the results that the bonding between the resin layer and foam… More > Graphic Abstract

Abstract As additive manufacturing technologies advance, new opportunities are opening up for their application in the furniture industry. Wood remains one of the leading raw materials in the furniture industry; therefore, possible options for combining it with 3D printing have been researched. The bonding of 3D-printed polymer parts with wood or 3D printing with wood-plastic composites is already known, but in our research we attempted to directly 3D print polylactic acid (PLA) on wood surfaces. The effect of printing parameters, as well as the surface preparation of wood on the shear strength of the bond between wood and on-printed material was… More >

Abstract A facile method, focusing on emulsification, chain extension and dispersion process in preparing waterborne polyurethane, was developed to prepare emulsion with rod-like nanoparticles. The facile method involves a water addition procedure by in situ generated water to react with polyurethane prepolymer instead of the external water addition process. As a comparison, waterborne polyurethane was synthesized through the external water addition process. According to the characterization methods including FTIR, ¹H-NMR, TEM and water swelling experiments, it is suggested there are two kinds of hydrogen bonds interactions in hard/soft domain of the novel polyurethane, and the phase separation of hard/soft domains increases… More > Graphic Abstract

Abstract Crumble rubber (CR) can be used to prepare CR and styrene-butadiene-styrene (SBS) composite modified asphalt with a good high-and low-temperature performance, meanwhile the addition of CR could work as the substitute for SBS and help reduce the content of SBS. This study contains three main parts: effect of preparation and effect of material composition as well as rheological performance characterization. Factors during the preparation, including shearing temperature, shearing time, mixing time and swelling time, were selected, while base binder, CR content, CR particle size and SBS content in material composition were considered. The effects of these factors were assessed in… More >

Abstract It is critical to study efficient, stable oxygen reduction reaction (ORR) electrocatalysts due to insufficient stability and expensive price of Pt/C catalysts for Zn-air batteries. Fe–N–C electrocatalysts was synthesized by a facile solvent-green method and the efficiency of Fe–N–C optimized was studied as potential ORR electrocatalysts under alkaline condition. Results indicated that it had excellent ORR activity with E_1/2 of 0.93 V, which was competitive to that of Pt/C-JM under the same conditions. Moreover, the assembled Zn-air battery exhibited discharge potential and charge potential of 1.2 V, 2.32 V at 5 mA cm⁻² with high stability, respectively. Overall, all results illustrated… More > Graphic Abstract
