A novel AB2 type amphiphilic miktoarm-star copolymer of alpha-methoxy-poly(ethylene glycol)-b-poly(gamma-benzyl-L-glutamate)2 was synthesized by ring-opening polymerization of gamma-benzyl-L-glutamate N-carboxyanhydride. The polymerization was initiated by the terminal amino groups of alpha-methoxy-omega-N,N-bis(aminoethyl) poly(ethylene glycol). Structural(More)
A novel ternary copper(II) complex, [Cu(phen)(L-Thr)(H2O)](ClO4) (phen=1,10-phenanthroline, L-Thr=L-threonine), has been synthesized and structurally characterized. The complex crystallized in a triclinic system with space group P1 , a=7.526(15) A, b=11.651(2) A, c=12.127(2) A, alpha=115.41(3) degrees , beta=102.34(3) degrees and gamma=91.33(3) degrees .(More)
Multinuclear Pt(II) complexes represent a novel class of antitumor agents. In this work, a dinuclear monofunctional Pt(II) complex {[cis-Pt(NH3)2Cl]2(4,4′-methylenedianiline)}(NO3)2 (1) was synthesized and characterized by 1H NMR, electrospray mass spectrometry, and elemental analysis. The 2D [1H,15N] heteronuclear single quantum coherence NMR spectra of(More)
A hierarchical microporous carbon material with a Brunauer-Emmett-Teller surface area of 1348 m(2) g(-1) and a pore volume of 0.67 cm(3) g(-1) was prepared from yeast through chemical activation with potassium hydroxide. This type of material contains large numbers of nitrogen-containing groups (nitrogen content >5.3 wt%), and, consequently, basic sites. As(More)
The basic principle of digital synchro converter (DSC) is introduced, analyzing how to use Micro Processor LPC2292 as its key part and other linear circuit to generate two sine and cosine to achieve the transforming method of from digital signal to synchro signal, completed a suit of the digital signal drives synchro interface system of autopilot steering,(More)
Introduces a suit of alarm system based on can-bus and ARM. Take LPC2292 Central Processing Unit and CTM1050 as its communication system key part, adopts other designs both of hardware and software, completed a suit of distributed signal detected and process system of autopilot steering. The system has the advantages of the alarm information be showed by(More)
Polyamic acid-TiO(2) hybrid colloid emulsion with an average particle size of 200 nm was formed by dispersing nano-TiO(2) into polyamic acid colloidal emulsion. The polyimide-TiO(2) nanocomposite was coated onto carbon fiber by electrophoretic deposition. The primary properties of polyamic acid-TiO(2) hybrid colloid emulsion and polyimide-TiO(2)(More)
According to the characteristics of the sewing machine, a new starting method was presented on the basis of the analysis on the characteristics of application of brushless DC motor, which is the three-step starting technique during the sewing machine starting. The experimental results indicate that this method significantly enhances the speed of starting(More)
