A novel multibranched chromophore containing carbazole moiety，4, 4´, 4´´-tris(9-carbazyl-trans-styryl) triphenylamine (TCSTPA)，was synthesized and characterized by 1HNMR and elemental analysis. A larger two-photon absorption (TPA) cross section of the chromophore was obtained as high as 2350 GM compared to that of the…
In this paper, nonlinear dynamic buckling of FGM shallow conical shells under the action of triangular pulse impact loads are investigated. The nonlinear dynamic governing equation of symmetrically FGM shallow conical shells is built. Using Galerkin method, the nonlinear dynamic governing equation is solved, and the n…
Retained austenite of Q&P (Quenching and Partitioning) processed 0.2C-1.51Si-1.84Mn steel heated in intercritical region and full austenite region are investigated. The results show that the maximum volume fraction of retained austenite heated in intercritical and full austenite region is 13.39% and 5.23% respectively…
A method to estimate the thermodynamic properties of Multi- component white gold alloys from those of constitutive binary alloys was proposed. The Miedema's theory and Chou model. were used to calculate the formation enthalpies of Au–Cu–Ag-Zn-RE alloys. The agreement between the calculation and experiment is reasonabl…
The compression behavior of closed cell aluminum foams with different density has been examined. Stress-strain curves were obtained. The microstructure evaluation of cell walls was investigated using X-ray computer tomography. A series of images of internal microstructures were given, the structural deformation evolut…
In this paper, density functional theory calculation combined with period slab models were used to investigate the interaction between fuel gas CO and different active site in Mn3O4(001) surface, the formation of bidentate carbonate species, the breakage of old bond along with generation of new bond in CO oxidation pr…
Preparing composites of broken glass and waste aluminum is one of the effective methods, which are high-added value utilizations of both wastes. It is an original thought which is used to develop circular economy and vein industry in china. The combination of aluminum’s toughness and glass’s hardness is the advantageo…
The hydrogel of the mixed oxide Al 2 O 3 -30% Y 0.1 Zr 0.9 O 2 was prepared by precipitation of ammonia from a water-alcohol mixture (1 : 5). The Al 2 O 3 -30% Y 0.1 Zr 0.9 O 2 compound thus synthesized was characterized using differential scanning calorimetry, transmission electron microscopy, and the BET adsorption…
Multi cage-like zinc oxides were prepared via a facile hydrothermal method. The as-synthesized materials were characterized by means of XRD, TG-DTA, SEM, EDS, and N2 adsorption. The results indicate that the molar ratio of glucose to zinc cation has a significant effect on the morphology, surface area, pore size and d…
This work compares the effects of SiN and Ta2O5barrier layers in a multi-level phase change random access memory (PCRAM) cell. The PCRAM cell comprises a phase change material stack between a top and a bottom electrode. The phase change material stack comprises a nitrogen-doped Ge2Sb2Te5(NGST) layer on top of a thin b…
Nanocrystalline porous silicon (nc-PSi), a material already widely studied for application in photonics, optoelectronics and sensing devices, is currently under investigation as an active element in photodetection and photovoltaic application as well. Thanks to its unusual properties such as a band gap widening compar…
Nickel(II) thiostannate is prepared in the NiCl 2 -SnS 2 -H 2 O system by precipitation from solutions. Its formation temperature and homogenization time are determined. The synthesis of NiSnS3 from the ammonium acetate buffer solution is found to last 6–8 h at 80–90°C. The elemental composition of ternary nickel(II)…
The research reported in this article is based on an NSF (National Science Foundation) project aimed at advancing the structural use of earth-based technologies through addressing durability concerns within the hot and humid context. This article focuses on one aspect of the research directed at developing an enhanced…
New composite electrochromic systems combining the advantages of low-molecular-mass organic electrochroms—high molar-absorption coefficients in the colored state and high switching rates—with good properties of polymers—such as mechanical strength and film-formation ability—are prepared through the incorporation of lo…
The paper shows the constituents and technical properties of low calcium aluminates cement concretes with ultra dispersed mineral powders and admixtures.
A plasma source is developed using a coaxial shunting arc plasma gun to extract a pure carbon ion beam. The pure carbon ion beam is a new type of deposition system for diamond and other carbon materials. Our plasma device generates pure carbon plasma from solid-state carbon material without using a hydrocarbon gas suc…
Intermittent changes in the number of pulsating bubbles under ultrasound are studied experimentally. The peak-to-trough intensity of the waveform of scattered light from cavitation bubbles corresponds to the number of pulsating bubbles. It is shown that the brightness of the illuminated bubbles in the captured images…
The theoretical basis of the method of accelerated life tests of nickel-cadmium batteries have been considered. The effect of self-discharge of a resource of nickel-cadmium batteries running in standby mode is shown. The effect of temperature on the rate of self-discharge Ni-Cd batteries is shown.
The structure and properties of iron-rich magnesia-spinel composite prepared using sintered iron-rich magnesia and MgO-rich spinel for burning zone of cement rotary kiln were analyzed. The results show that fine-grained magnesioferrite precipitation and magnesiowustite improved the flexibility of magnesia. The formati…
