    Microdetermination of proteins by enhanced Rayleigh light scattering spectroscopy with morin (1999)
    Springer
    Fresenius' journal of analytical chemistry 364 (1999), S. 560-564

    Notes: Abstract Under acidic conditions, the reaction between 3,5,7,2′,4′-pentahydroxyflavone (morin) and proteins enhances the weak light scattering of morin drastically. The enhanced light scattering intensity is proportional to the content of proteins. This fact is the basis of a new method for the quantitative analysis of proteins. The linear range is 0.45–7.15 and 0.46–11.14 μg/mL for BSA and HSA, respectively. The relative standard deviation is 3.76% (n = 12) for BSA in the middle of the linear range. The results of this assay for human serum samples were comparable with those from the traditional method (CBB method). There is almost no interfere from amino acids and most of the metal ions. The scattering spectrum of morin was also discussed.

    Notes: Based on the favorable effect of the elements Al and Si on the improvement in reducing hydrogen permeability, a new combined process of simultaneous aluminizing and siliconizing, followed by oxidizing treatments using double glow plasma technology on 316L substrate was developed in this work. Microstructure and phase structure of as- prepared coating was examined by scanning electronic microscopy (SEM), X-ray diffraction analysis (XRD), transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS), respectively. The results showed that the simultaneous aluminizing and siliconizing coating consisted of an outer aluminide layer (dissolved Si) and a diffusion zone. After a combined process, a continuous and compact Al2O3-rich coating was formed at the outermost surface. SiO2 was also detectable in the oxide coating

    Notes: In cement industry, many grinding up systems are on operating now. The tradition process of tube mill grinding system is high energy consumption, so it’s low efficiency, especially in the final cement grinding process. The value and advantage of slag is recognized more and more, but it’s difficult to be grinded up. Furthermore, the disadvantage and shortages to grind up clinker compounded with slag to produce cement are obvious and adopted. The best process is to grind up slag, clinker separately. Then, these two kinds of powder are compounded by a mixer. Hereby, it introduces a design of the process to grind up clinker, slag by one roller mill

    Notes: We report for the first time on RF SiC BJTs fabricated on semi-insulating (SI) substrateswith L-band performance. Small-periphery (4x150μm) devices were tested using on-wafer load-pullmeasurements up to 1.5GHz. Under pulsed conditions, the devices exhibited 10dB of power gain at1GHz and a peak power density of 2.3W/mm (1.4W) with a 100μs pulse width and a 1% duty cycle.The power gain decreased to 8dB at 1GHz under CW conditions at a power density of 1.6W/mm(1W). The load-pull measurements were performed up to 125oC, which resulted in a 1 dB reductionof power gain compared to the room temperature performance. Results at 0.5 and 1.5 GHz arepresented as well

    Notes: Dyes are colored organic compounds that are used to pigment fiber or other materials. Dyes aremainly calssified into natural and synthetic dyes in terms of the origin. Natural dyes include animaldyes, plant dyes and mineral dyes with such defects as incomplete chromatogram, inconvenient useand color fading, and thus have been gradually eliminated. In 1856, the 18-year-old young Britishscientist Perkin successfully invented the world's first synthetic dyes. He built his own factory andindustrialized synthetic dye production. Over 100 years since then, dye industry has undergonerapid development, and by 2001 synthetic dyes already have been up to nearly 10,000 varieties. In2004, the output of total dyes in the world has reached 900,000 tons. Synthetic dyes are usedcomprehensively, not only to dye synthetic fibers, but also natural fibesr, fur, leather and man-madefibers

    B–Hδ−σ bond as dihydrogen bond acceptor: Some theoretical observations and predictions (2002)
    College Park, Md. : American Institute of Physics (AIP)
    The Journal of Chemical Physics 116 (2002), S. 25-32

    Notes: BH3NH3 dimer and BH3NH3 complexes of methane, hydrogen cyanide, ammonia, water, methanol, and hydrogen fluoride, are studied using the Møller–Plesset second-order perturbation theory and the 6-31++G** basis set to understand the features of dihydrogen bond. Complex binding energy is corrected for the basis set superposition error with the counterpoise method and for the zero point energy. Natural bond orbital analysis is used to discuss the charge transfer. Computed results indicate that dihydrogen bond does not occur in both BH3NH3...CH4 and BH3NH3...NH3 complexes. Apart from the B–Hδ−...H–N hydrogen bond (H bond) found previously in the BH3NH3 crystal, the B–H...H–X (X=C,O,F) H bonds have been observed in BH3NH3...HCN, BH3NH3...H2O, BH3NH3...CH3OH, and BH3NH3...HF complexes. As for the complexes in which only dihydrogen bonds appear the strength of dihydrogen bonds ranges from −13.9 to −20.5 kJ/mol. While the formation of BH3NH3 complexes, the weakest B–N bond of BH3NH3 contracts (its stretch appears blueshifted), and both B–H and X–H bonds in the B–H...H–X H bonds elongate slightly owing to the charge transfer from σ(B–H) to σ*(X–H), and the B–H...H tends to be bent. The charge transfer is generally proportional to the second-order perturbation energy lowering (ΔE2) due to the interaction of frontier orbitals in σ→σ* and n→σ* cases, and the threshold value (1.5 kcal/mol) of ΔE2 as one of the indices for judging the existence of dihydrogen bonds is recommended. © 2002 American Institute of Physics.

    Simulation of the Residual Stress of Cold-Formed Thin-Wall Steel Members and Calculation of Load under Its Influence (2005)
    s.l. ; Stafa-Zurich, Switzerland

    Notes: Because of the particularity of distribution of the residual stress of cold-formed thin-wall steel members, now there has not yet been a proper method for directly considering the influence of the residual stress in calculating the reliable capacity of carrying load of cold-formed thin-wall steel members, and such is the typical case in China’s National Technical Specification of Cold-formed Thin-wall Steel Structures GB50018-2002. With the cold-formed thin-wall channel steel taken as specific object in this study as well as assumed to be ideal elastic-plastic body, their finite modular models are set up in ANSYS. According to the tested results and the distributing rules of residual stress, the models of the residual stress of cold-formed thin-wall channel steel are established close to the factual data, and also the initial stress file is set up that can describe the magnitude and distribution of the residual stress. The file has two features: first, it is likely to find out about the rules of the cold-steel residual stress varying in the direction of thickness by using the values of residual stress at some integral points in thickness direction of a specified module , and second, it is applicabled to simulate various distributions of residual stress. So theultimate load of the member can be worked out and elastic-plastic calculating problemof cold-formed thin-walled steel sections can be easily solved by introducing theinitial stress file into the stability analysis of ANSYS
