This paper demonstrates a facile and low-cost carbothermal reduction preparation of monodisperse Fe3O4/C core-shell nanosheets (NSs) for greatly improved microwave absorption. In this protocol, the redox reaction between sheet-like hematite (α-Fe2O3) precursors acetone under inert atmosphere elevated temperature generates NSs with morphology inheriting from α-Fe2O3. Thus, different sizes ( a) nanopolyhedrons are obtained by using precursors. Benefited high crystallinity Fe3O4 core thin...
Fe3O4 and Fe nanowires are successfully fabricated by electrospinning method reduction process. Wiry microstructures were achieved with the phase transformation from α-Fe2O3 to partial full reduction, while still preserving wire morphology. The diameters of approximately 50–60 nm 30–40 nm, respectively. investigation microwave absorption reveals that exhibit excellent absorbing properties. For paraffin-based composite containing 50% weight concentration nanowires, minimum reflection loss...
A facile template-free and one-pot thermal decomposition approach was used for the mass preparation of submicrometer-sized NiO octahedra. Ni octahedra with tailored crystallization texture characteristics are easily achieved through H2-annealing at various temperatures. The good morphology retention is due to principle minimum surface free energy as well similar crystallographic system that NiO. Studies on static magnetic microwave electromagnetic properties reveal relationships among...
Electromagnetic wave (EMW) absorbing materials have attracted much attention in recent years due to the dramatical increase of high-frequency electronic components and devices, which generate electromagnetic (EM) pollution cause serious interference (EMI). Ceramics associated (nano)composites are widely investigated as EMW because their excellent mechanical properties, chemical/thermal stabilities, oxidation/corrosion resistance. In addition outstanding performance, lightweight, flexibility...
Abstract Ti 3 C 2 T x nanosheets have attracted significant attention for their potential in electromagnetic wave absorption (EWA). However, inherent self-stacking and exorbitant electrical conductivity inevitably lead to serious impedance mismatch, restricting EWA application. Therefore, the optimization of matching becomes crucial. In this work, we developed polymethyl methacrylate (PMMA)@Ti @SiO composites with a sandwich-like core-shell structure by coating SiO on PMMA@Ti . The results...
Abstract. There are numerous influencing factors of the risk consequences dam break. The scientific and reasonable index system its weight distribution some key elements for comprehensive evaluation break risk. Taking into consideration 20 factors, including hazards, exposure vulnerability, is constructed. Using Statistical Cloud Model (SCM) to improve entropy method, we establish calculation model consequences. results shows that top five with highest population, flood intensity, alert...
Abstract TaB 2 -SiC coating modified by different content of MoSi was fabricated on graphite substrate with SiC inner liquid phase sintering to elevate the anti-oxidation capability coatings. As compared sample —40wt%SiC coating, exhibited a weight gain trend at lower temperatures, fastest loss rate went down 76%, and relative oxygen permeability value reduced from about 1% near 0. More importantly, large amount SiO glass produced over during oxidation in contact modification , which proved...
Abstract SiBN ceramics are widely considered to be the most promising material for microwave-transparent applications in harsh environments owing its excellent thermal stability and low dielectric constant. This work focuses on synthesis ceramization of single-source precursors preparation as well investigation corresponding microstructural evolution at high temperatures including molecular dynamic simulations. Carbon- chlorine-free perhydropolysilazanes were reacted with borane dimethyl...

On the basis analytical results (Pb) dioxide (PbO2) contents scrap paste, certain amount grid was used as reductant to transform excess PbO2 into sulfate (PbSO4). systematically studies influence concentration sulfuric acid (H2SO4) catalyst reaction temperature on process. The...
Abstract Polysilazane coatings have a broad need in real‐life applications, which require low processing or working temperature. In this work, five commercially available polysilazanes been spin‐coated on polycarbonate substrates and cured ambient environment temperature to obtain transparent, crack‐free, dense films. The degree of crosslinking is found significant impact the hardness Young's modulus polysilazane films but has minor influence film thickness hydrophobicity. Among all...
