Phenanthro[9,10-d]-imidazole( PI) unit has attracted extensive attentions in organic optoelectronic field due to its intrinsic wide band gap,high luminescence efficiency,good thermal stability,balanced charge carrier injection and transport property as well as low fabrication cost. In this manuscript,the recently repo…
A series of ammonium oxidative-thermoregulated bifunctional ionic liquids (ILs) have been synthesized by introducing the thermoregulated structural unit (PEG chain) into ammonium cation and using heteropolyanion as catalytic oxidation group. The prepared ionic liquids have the thermoregulated solubility in toluene/n-d…
The split Hopkinson pressure bar(SHPB) technique and the wave propagation inverse analysis(WPIA) technique are both extensively used to experimentally investigate the impact behavior of materials, although neither of them alone provides a fully satisfactory analysis. In the present paper, attention is given to new exp…
Nano melamine cyanurate(NMC) was synthesized by a solvothermal method,and characterized by FTIR,XRD and SEM.The effect of solvents,surfactants,reaction-temperature and-time on the particle size of the product were investigated.NMC can be only obtained by using distilled water as a solvent,and of which the average part…
Paint coating thickness uniformity is investigated with a double beta spray gun model to investigate the coating thickness distribution assuming that the robot spraying coating shape is oval. Then,the coating mechanism is analyzed for the spray gun model. The relationship between the coating thickness variation and th…
Understanding cell interaction with one-dimensional nanomaterials, including nanotubes, nanowires, nanofi bers, fi lamentous bacteria, and certain nanoparticle chains, has fundamental importance to many applications such as biomedical diagnostics, therapeutics, and nanotoxicity. Here, we show that cell uptake of one-d…
A novel method for detecting Cu2 +ion was developed based on the fluorescence quenching effect of copper ion on carbon dots( CDs). The fluorescent probe was prepared by grafting reduced carbon dots( rCDs) in calcium alginate to form a calcium alginate film( CA-rCDs). Fluorescence characteristics of the probe and inter…
Low-foam penetrating agents have been sought after for many industrial applications. In this paper, we were aiming at a low-foam penetrating agent with excellent wetting ability and hydrolysis resistance, various silicon- terminated penetrating agents were designed and synthe- sized starting from a popular commercial…
The low-cycle fatigue tests have been conducted for the Mg-7%Zn-0.6%Zr-0.5%Y alloys(mass fraction) subjected to extrusion, aging(T5) and solution plus aging(T6) treatment, respectively. The influence of heat treatment on the fatigue deformation behavior of the alloy has also been systematically investigated. The resul…
Well organized Cu-Ti-O nanotube arrays with enhanced visible light response were prepared on Cu30Ti70 alloy substrate by anodization. The influences of anodization time on the morphology, crystalline structure and photocatalytic activity of Cu-Ti-O nanotube arrays were further investigated. The results show that the s…
通常生产的 35CrMo 寒冷标题钢必须经历在冷标题过程前退火的 spheroidization。在这份报纸，有各种各样的控制冷却时期的变丑过程的不同类型被操作用 Gleeble-3500 模拟技术完成联机球状的渗碳体。根据测量动态铁酸盐转变温度(Ad3 ) ，变丑能被划分成二种类型：在 810 和 780 点的低温度变丑？
In order to recover the additive lithium chloride in the polyphenylene sulfide production,the disolution of lithium chloride and sodium chloride in solvent N-methyl pyrrolidone(NMP) was studied.By using laser diffraction assistance method,solubility data of lithium chloride and sodium chloride in NMP were measured bet…
The microstructural characteristics and formability at the edges of low carbon pickled steel sheets have been investigated based on the generation of earing and cracking defects while drawing. The microstructure of the edge features coarse grains and mixed sized grains. The strength of the sheet edge is slightly lower…
A new kind of bio-inspired, lightweight structure was designed and built from carbon fibre prepreg based on the cross-sectional microstructure of a beetle’s elytra. The compression strength and failure process of the resulting structure was analysed using the finite element method; while at the same time, a quasi-stat…
Cold-drawn pearlitic steel wires exhibit ultrahigh strength and have important applications where high strength and wear resistance are required.The hypereutectoid compositions present a promising potential for increasing the mechanical properties,especially the strength.The austenitization process strongly influences…
In order to understand the effect of thermo hydrogen treatment(THT) on high temperature tensile behavior of a Ti2AlNb based alloy plate, high temperature tensile tests of Ti-22Al-25Nb alloy plates without and with 0.2%H(mass fraction) charging were conducted with strain rate of 2.5×10- 2s- 1at 870, 900, 930 and 990℃ r…
The thermal scratch seriously affects the surface quality of the cold rolled stainless steel strip. Some researchers have carried out qualitative and theoretical studies in this field. However, there is currently a lack of research on effective forecast and control of thermal scratch defects in practical production, e…
Aiming at the characteristics and current status of refineries' odor pollution, the sulfur containing odor gas-hydrogen sulfide was chosen as a typical object and treated by using the adsorption-catalytic oxidation method in the laboratory. This research focused on the preparation of adsorptive catalyst with high sulf…
By using nonequilibrium Monte Carlo simulation approach,the shearing effects on the sol-gel transition of ABA telechelic triblock copolymers in a B block selective solvent were investigated. The simulation results show that the shear makes the sol-gel transition concentration area shifting to lower concentrations. Mic…
Laryngeal carcinoma is poor prognosis and patients with laryngeal carcinoma usually present late leading to the reduced treatment efficacy and high rate of recurrence. Incidence and mortality rates of laryngeal carcinoma are equivalent,suggesting a failure of current therapies,despite the variety of combined modality…
