The thermo-responsive hydrogels poly(N-isopropylacrylamide) (PNIPAm) were synthesized by frontal polymerization (FP) in dimethylsulfoxide (DMSO) and ethanol mixture. The effects of composition of synthesis-solvent on FP feature and porous morphologies as well as their response behavior of the final products were studi…
Summary form only given. Metamaterials, which are composed of small periodic microstructures, are functional media with extraordinary properties for electromagnetic waves. When a metamaterial includes plasmas in its main part, which we refer to as a “plasma metamaterial,”1it can provide a novel field where plasmas and…

We consider systems of particles in two dimensions with negative dielectric permittivity and sharp corners. The field divergences near the corners of the inclusions are non-square-integrable for negative permittivities in a range depending on the corner angle, and the leading term for small distances is provided by th…
The monitoring of the state of the insulation and it's interpretation is an important and challenging task. In order to monitor the state of the insulation after application of various voltages under DC and AC conditions, the samples of the paper insulating material Leatherite paper was observed under Scanning Electro…
Summary form only given. A requirement for the development of EUV (5–50 nm) laser applications is a pulse power driver system that can deliver high peak currents and fast rise-times in order to be able to pump these lasers effectively. We report here the initial results in the development of a high current driver that…
Nowadays in China, excessive import of boron isotope has always been the bottleneck to its industrial applications in nuclear, mechanical, steel and electronic fields. To pull the boron industry out of the mire of import, it is prerequisite to study the enriching and refining of boron isotope. In this work, we present…
Summary form only given. Metal puff Z pinch is a novel and promised way to produce soft X-ray radiation sources based on Z pinchespp]1|. Authors of Ref.2 has been studied the performance of a metal double puff Z-pinch system (450 kA, 450 ns). In this type of system, the outer and inner cylindrical shells were produced…
Effects of the water temperature, water addition, sucrose and the phosphate monoester starch on the transparency of corn starch dumpling wrappers were investigated by orthogonal experimental design method. Range analysis and variance analysis methods were carried out to analyse the test results. The results showed tha…
Flexible displays, flexible paper related electronic products are important development tendency in micro-electronics industry. At present, increase the adhesive strength between flexible organic substrates and ITO film quickly and efficiently and ensure the reliability of the adhesive between them is a burning questi…
In 2012, the Journal of Natural Products has reached a major milestone, through the publication of volume 75. The journal first appeared in 1938 under the title Lloydia , and was published by the Lloyd Library and Museum, Cincinnati, Ohio. The founding Editor of Lloydia was Theodor K. Just, who continued in this posit…
Heteropoly acide(HPA), as one kind of solid-super acid catalysts, has been researched and applied extensively. Using SBA-15 and ZSM-5 as carriers, HPA catalysts with different types and contents were applied in this work for the hydrolysis of dimethyl ether(DME). It had been found that ZSM-5 was a proper carrier, and…

With the increasing demand for light-weight materials to reduce fuel consumption, the automobile industry has extensively studied magnesium alloys which are light weight metals. The intrinsic poor formability and poor ductility at ambient temperature due to the hexagonal close-packed (HCP) crystal structure and the as…
It is impossible to inspect contact/via hole on wafer through optic inspection system because of resolution. Now, Single-electron beam inspection system is used for it. But sample test below 10% is done because this method is quite slow on inspection. Micro-column is available in multi column array, high speed inspect…
Summary form only given. Flashover phenomena in vacuum restrict the performance of insulation system, which has been paid much attention by many researchers. However, due to the rapidity and complexity of flashover development process, the mechanism of surface flashover phenomena is still not fully understood. In this…
An efficient power pattern synthesis of contoured beam reflectarrays is presented. Using the presented synthesis technique, an offset dual-polarized contoured beam reflectarray to cover an European region with cross-polar and sidelobe suppression has been designed. Simulations show that the presented technique allows…
In this communication, Artificial Impedance Surfaces (AIS) based on patches from High Impedance Surface (HIS) are considered. The possibility to use the patch width as an additional degree of freedom for antennas design is investigated. Within the limitation of a single linear polarization, rectangular patches of this…
Numerical simulation of the die for cylinder upsetting is done by Marc AutoForge software on base of elastic-plastic theoretical mechanical model to analyze transient temperature field, equivalent total strain field and thermal strain field. Then qualitative and quantitative relationship is found between these Factors…
Using fractal theory simulation of dendrite crystal DLA growth model of pure substance, the undercooling during solidification process of crystal nucleation is simulated; and then in the crystal nuclei are formed on the basis of a pure substance, the phase field model and combined with the finite difference method fur…
