Abstract: X‐ray diffraction methods for estimating the metamorphic grade of diagenetic, anchizone and epizone in metapelites are reviewed and applied to samples from a 7000 m+ borehole in western China and surface samples from the surrounding Zoigê area. Kübler's illite crystallinity (IC) measurements provide more con…
Based on the analysis of the interaction of the nano-particles and the matrix interface layer, assuming when the elastic properties of the interface layer change the total energy difference arising from it transfer to the nanoparticle surface, the effective elastic moduli of the nanoparticles with interface equilibriu…
Abstract Summary: The micro‐structure evolution of isotactic polypropylene‐1‐butene (iPPBu) and polypropylene‐ethylene (iPPEt) random copolymers with 4 mol% of 1‐butene and ethylene was respectively investigated by differential scanning calorimetry (DSC) and in‐situ small angle X‐ray scattering (SAXS) techniques durin…
Due to unavoidable tolerances in components construction and assembly, the actual magnetic field in Tokamak devices differs from the nominal one. The experimental studies nowadays available indicate a strong impact of the error fields on the plasma stability in next generation, large size, devices. Therefore, a carefu…
Abstract Fluorine‐containing polyester (FPE) was synthesized by the reaction of phthalic anhydride, epichlorohydrin, and 2,2,3,3‐tetrafluoropropyl glycidyl ether (TFGE) at the catalysis of tetraethylammonium bromide using 1,4‐butanediol as the initiator. The structure of FPE was characterized by 1H NMR and 19F NMR, an…
The effect of vinyl acetate (VA) content on the Properties of Intumescent flame retardant ethylene-vinyl acetate copolymer (IFR EVA) material was studied. Ammonium polyphosphate and pentaerythritol (APP/PER) was used to prepare the IFR EVA materials. The burning behavior, thermal stabilization, and mechanical properti…
Benziphthalocyanine (bzpc) and dicarbahemiporphyrazine (dchp) are phthalocyanine analogs where one and two of the isoindoline units have been replaced with benzene rings. In this report, we present dchp and bzpc analogs 1 and 2 where CF3 groups have been placed on the 5-position of the benzene rings. Compounds 1 and 2…
One approach had been developed for the covalent modification of graphene sheets: amidation and esterification of graphene oxide (GO). Graphene oxide was synthesized by oxidizing graphite in strong acid and lots of oxygen-containing groups, such as hydroxyl and carboxyl processed in the carbon layers, made GO strongly…
In this study, biomimetic synthesis of hydroxyapatite (HAp) nanocomposites based on bacterial cellulose (BC) with sodium alginate (SA) surface modification was studied. The results showed that SA treatment promoted the apatite nucleation ability of BC in SBF solution. The FE-SEM images demonstrated that HAp nanopartic…
The manufacturing process of particle composite for furniture, made of waste paper and wood particle, was studied and discussed in this paper, and an ornament cabinet and a Chinese style teapoy were assembled in the laboratory with the composite. The results showed the mechanical properties of composite made of waste…
This paper presents results on the generation of molecular phosphorus ion beams in a hot filament ion source. Solid red phosphorous is evaporated mainly as tetra-atomic molecules up to a temperature of 800°C. Thus, one of the main conditions for producing maximum P(4)(+) fraction in the beam is to keep the temperature…
Non-conductive substrates, such as silicon wafers, have usually been used to synthesise carbon nanotubes (CNTs). However, in applications such as electrodes, it is desirable to have CNTs grown on conductive buffer layer and conductive substrates. Vertically aligned multiwall CNTs were grown on Ni/TiO2/Ti substrates by…
To remanufacture hard chromium-plated workpiece, nano-Al2O3/Ni-Co composite coatings and Ni-Co alloy coatings are developed using electric brush plating technology. Scanning electron microscopy (SEM) and transmission electron microscope (TEM) are used to analyze the surface morphology, phase structure and wear propert…
The structure of the synthesized title compound is characterized by IR, UV-visible spectroscopy, and single crystal X-ray diffraction (XRD). The new compound (C 18 H 23 NS) crystalizes in the monoclinic P 2 1 / c space group. In addition to the crystal structure from the X-ray experiment, the molecular geometry, vibra…
The presence of long-lived radionuclides is a challenge to the management of high level liquid waste (HLLW). Separation of minor acitinides and long-lived fission products from the HLLW by partitioning process has the potential of significantly decreasing the costs of the immobilization and disposal of the radioactive…
We report on the results of experimental and theoretical investigation of the shape of an acoustic pulse generated in alkali-halide crystals by a pulsed electron beam with a maximal electron energy of 0.28 MeV and an energy density of 0.10–0.65 J/cm 2 . It is found that the shape of the acoustic pulse for the given be…

All the material components have been synthesized using the sol-gel method. The…
The rice husk ash/natural rubber (RHA/NR) composites were prepared by latex blending process using the RHA modified with silane coupling agent. The structure and morphology of modified RHA were studied. The dispersing performance of modified RHA in the composites was evaluated from the structure and thermal properties…
The spectrum of surface polaritons in an antiferromagnetic material with a spiral magnetic structure and spin-induced electrical polarization at a boundary with a metal in a magnetic field is analyzed.
