In this work, a series of novel bipolar copolymers containing 8-hydroxyquinoline aluminum (Alq3) and carbazole had been synthesized by copolymerization of a novel Alq3 complex monomer and N-vinylcarbazole (NVK), and characterized by Fourier transform infrared spectra (FTIR), gel permeation chromatography (GPC) and dif…
Liquid energetic materials were not tested through traditional test methods for thermal sensitivity. Accelerating Rate Calorimeter (ARC) was scientific to test thermal sensitivity of energetic materials. The decompositions of Hexogen (RDX), Octogen (HMX), 2,4,6-Trinitrotoluene (TNT), Nitromethane (NM), Iso-propyl Nitr…
The Flexible Intermediate Bulk Container (FIBC) is a flexible transportation packaging container that is weaved by polyolefin plastic ribbon-like filament, which is widely used in the storage and transportation of granular and powder materials. When the FIBC was affected by environment factors synthetically under usin…
A novel magnetic bearing system for gas turbine generators of next generation nuclear power plant is proposed. This system newly adopts saturated coils for generating main bias force and small size linear auxiliary coils for stabilizing the suspension. The saturated coils operate in the region of magnetic saturation i…
We reported that titania ceramic coating loaded with palladium catalyst worked as an optical hydrogen gas sensor at room temperature. The palladium metal of this sensor worked as a catalyst not only for room-temperature operation but also for high selectivity to hydrogen gas. Precise control of metal/ceramic interface…
Features of the preparation of magnetic semiconductor films with the composition Mg(Fe0.8Ga0.2)2O4−δ on a 200-nm-thick silicon substrate are presented. Both a pure substrate surface and one with protective TiO x layers with a crystallization temperature of 900–1000°C for 30 min were used. The effect of the protective…
The polysulfone membranes surface modification by the low temperature air plasma for the study. The PS membranes surface composition, filtration, antifouling characteristics with the modification was characterized by water contact angle, water fluxes, interception rate. Polysulfone membranes hydrophilic has been great…
Coir mat reinforced unsaturated polyester composites have been prepared and the impact toughness has been researched, and the impact toughness model has been established based on the coir weight percentage content, the change laws of each mechanical index have been detailed, thus the optimal solutions have been put fo…
We propose that the product of the density by the square of the rms velocity of strain waves, which exhibits the features typical of elastic moduli, be referred to as effective (or characteristic) elastic modulus. The ratio of the bulk compression modulus to the effective elastic modulus is a single-valued function of…
We investigated the structure transition and the electrocaloric effect in PbZr1-xTixO3 (PZT) with x=0.7, 0.8 and 0.9. The results show that 50 MV/m can make the structural transition be a continuous one. When x=0.7, 0.8 and 0.9 at the zero field, the first order structural transition occurs at T0=685, 687, and 698 K,…
In this paper, a technology of determining the melt viscosity of a polystyrene(PS)/supercritical CO2solution using a linear capillary tube die mounted on a foaming dynamic extruder is presented. CO2was injected into the dynamic extrusion barrel. Single-phase PS/CO2solutions were formed using a microcellular extrusion…
Traditionally, materials characterization instrumentation has focused mainly on particles. However, for a better fundamental understanding and various potential applications, it requires an increase in the ability of instrumentation to observe.Characterization and manipulation requires not only extreme sensitivity and…
The low-temperature chemical crosslinking of a copolymer of vinylidene fluoride and tetrafluoroethylene was studied through various physicochemical methods. The reaction was conducted in solution in the presence of diethylenetriamine as a crosslinking agent. The penetration of the mixture molecules and the crosslinkin…
In this study, we aimed at exploring a layer of radio frequency (RF) sputtered titanium dioxide (TiO2) film on a sputtered ZnO film treated by hydrothermal reaction and then conducted characterization of the film. The main objective was to discuss characteristics of the fabricated TiO2 films under conditions of differ…
In this work we describe the studies of preparation and stability of liposomes formed by 1,1'-[(3,5-didodeciloxycarbonyl-4-phenyl-1,4-dihydropyridine-2,6-diil) dimethylebispyridinium dibromide, novel lipid-like compound. The influence of the amount of amphiphilic compound, solvent and sonication time was studied. Lipo…
Design a practical and effective hydrodynamic cavitation experimental apparatus, the establishment of cavitation radical scavenging method, the use of methylene blue to study the relationship of the hydroxyl radical production and cavitation cavitation intensity, the study of the various factors of cavitation radical…
Radio interference (RI) of DC transmission lines due to the corona discharge has become a restraining factor of power grids design and operation, so the suppression of RI is very important. In this paper, a new idea for suppressing RI by mounting ferrite cores on the conductor is proposed. By measuring and comparing R…
CZTS thin films were fabricated through sulfurization of sputtered alloy precursors. The properties of CZTS films obtained at sulfurization time of less than 2 hours and at H2S concentrations of higher than 15% were investigated. Sulfurization time of 30 min, 60 min and 90 min and H2S concentrations of 20%, 40% and 60…
Finite-element time-domain simulations of nonlinear eddy current problems require many solutions of large, sparse systems of equations. Modelorder reduction in connection with some suitable approximation to the nonlinearity is a powerful strategy for reducing the computational effort for such systems. This paper shows…
Serpin (Serine Protease Inhibitor) widely distributes in animals, plants, protozoan, prokaryotes and viruses. Serpin-6 belongs to the superfamily of serine protease inhibitor. In this study, we constructed a prokaryotic vector - pET28a-serpin-6, and used IPTG (isopropyl thiogalactoside) to induce serpin-6 protein expr…
