1.  纳米核壳式铜-锡双金属粉的制备及性能研究  被引次数:6
   牟国俊  赵 斌《无机化学学报》,2004年第20卷第9期
   A kind of novel core-shell Cu-Sn bimetallic nanoparticles has been prepared by a new method (displacement method), in which Sn was made to cover on the surface of Cu nano-core. The preparation method and reaction mechanism have been discussed. This reaction happened under the existence of coordinate agent-(NH2)2CS and protective agent PVP. The nanoparticles prepared were with a core-shell structure, granule diameter between 50~100 nm and good dispersing capability. The Cu-Sn nanoparticles proposed has better oxidation-resistant ability than Cu nanoparticles with corresponding granule diameter and can be applied as lubricant additives as well as antibacterial agent. When the additive amount is very low (0.1wt‰~0.5wt‰), it can improve the PB of the lubricant by 92%~106%, and also enhance its antiwear characteristics and friction-reducing properties. At the concentration of 1 000 ppm, it can reach an antibacterial ratio of 99.99%.

   A magnetic and thermosensitive poly(N-isopropylacrylamide)(PNIPAM) nanoparticles were prepared by the following procedure. The core-shell composite microparticles were synthesized by precipitating polymerization with Fe3O4 being entrapped with SiO2 as core and cross-linked PNIPAM as shell. Then, the SiO2 core was etched by hydrofluoric acid and magnetic thermosensitive Fe3O4/PNIPAM particles were formed. It has also been shown that the Fe3O4/PNIPAM nanoparticles are featured by lower critical solution temperature (LCST) at 33.0 ℃ while the temperature varies from 28.0 ℃ to 36.0 ℃. The composite magnetic thermosensitive particles were characterized by XRD, SEM, TEM and FTIR. The synthetic mechanism is also discussed.

4.  Emission spectrum from an Al/Mg tracer in the blow-off region of a radiatively ablated capsule  
   蒲昱东  陈伯伦  张璐  杨家敏  黄天晅  丁永坤《中国物理 B》,2011年第20卷第9期
   A study of X-ray emissions from Al/Mg tracers buried at two different depths in a plastic shell is presented. The X-rays originating from the K-shell transitions of the Al/Mg ions begin to irradiate after the ablative heating wave has passed through the trace layer and are recorded with a streaked crystal spectrometer. Only emissions from the capsule with the trace layer buried at a smaller depth are observed. Hydrodynamic simulations and a collisional—radiative model including detailed atomic physics are used to investigate the measured spectrum. It is found that the effects of the radiative heating play important roles in the formation of the K-shell emission. The time correlation between the simulations and the measurements is obtained by comparing the measured time profile of the He α emission with the calculated one. The line ratio of Ly α to He α is also calculated and is found to be in fairly good agreement with the experimental data. Finally, the relation between the time profile of the He α emission and the ablation velocity is also discussed.    

5.  稀土红色荧光粉SrZnO2∶Eu3+的发光性能  被引次数:4
   贺香红  周健  李卫华  周全法《无机化学学报》,2006年第22卷第9期
   A series of novel luminescent materials, SrZnO2∶M (M=Eu3+, or Eu3+ + Li+) have been synthesized by high-temperature solid-state reaction. The structure and luminescence properties of SrZnO2∶Eu3+ phosphor were studied through XRD, photoluminescence and Raman spectroscopy. The excitation spectra show a broad intense band and a number of small peaks corresponding to the inner 4f-shell excitations of Eu3+ (the strongest one is at 395 nm for 7F0-5L6). After SrZnO2∶Eu3+ phosphor was co-doped with Li+ ions, its charge transfer band extended to longer wavelengths. This resulted in increase of luminescent quantum efficiency of the sample. SrZnO2∶Eu3+,Li+ phosphor can be efficiently excited by longer UV. From the fluorescence spectrum of SrZnO2∶Eu3+ phosphor, apart from transition emissions of 5D07FJ (J=0~4), the transition emissions from 5D17FJ (J=0~2) have been observed. For the SrZnO2∶Eu3+ phosphor, under excitation of UV, the dominant emission is at about 612 nm, due to the 5D07F2 hypersensitive transition. The incorporation of Li+ ions greatly enhanced the luminescence intensity and made emission peak from 5D07F2 transition red-shifted.

   刘洋  余尧  高文桂  谌喜珠  谢笑天  刘伟平《无机化学学报》,2006年第22卷第11期
   Cis-diaminedithiocyanatoplatinum(Ⅱ) (cis-[Pt(SCN)2(NH3)2]) was prepared and characterized through content analysis of Pt, MS, IR. The results show that the complex has cis configuration and the bond type of Pt and SCN- is Pt-S. When the aqueous solution of the complex was stored for one week, an orange-yellow precipitation appeared, different from the complex with light yellow color. Further comparative studies of these two complexes suggested that the precipitation is cis-[Pt(NCS)2(NH3)2], the linkage isomerism of cis-[Pt(SCN)2(NH3)2]. The mechanism of the isomerism reaction is also discussed.    

7.  A simple linear sweep voltammetric method for the determination of double-stranded DNA with malachite green  
   W. Sun  J. Y. You  X. Hu  K. Jiao《Chemical Papers》,2006年第60卷第3期
   In pH 3.5 Britton—Robinson buffer solution double-stranded (ds) DNA can react with malachite green (MG) to form an interaction complex, which resulted in the decrease of the electrochemical response of MG, MG had a well-defined second-order derivative linear sweep voltammetric peak at −0.73 V (vs. SCE). After the addition of dsDNA into MG solution, the reductive peak current decreased with the positive shift of peak potential, which was the typical characteristic of intercalation. Based on the interaction, an indirect electrochemical determination method for dsDNA was established. The optimum conditions for the reaction were investigated and there were little or no interferences from the commonly coexisting substances. The decrease of peak current was linear with the concentration of dsDNA over the range of 0.8–12.0 μg cm−3 with the linear regression equation as ΔI p″/nA = 91.70 C/(μg cm−3) + 74.55 (n = 10, γ = 0.990). The detection limit was calculated as 0.46 μg cm−3 (3σ). The method had high sensitivity and was further applied to the dsDNA synthetic samples with satisfactory result. The interaction mechanism was discussed with the intercalation of DNA-MG to form a supramolecular complex and the stoichiometry of the supramolecular complex was calculated by electrochemical method with the binding number 3 and the binding constant 2.35 × 1015 (mol dm−3)−3.

   New data for the diffractive reaction p+N→ [Σ0 K +] +N at E p= 70 GeV were obtained with partially upgraded SPHINX setup. The data are in a good agreement with the results of our previous study of this reaction. In the mass spectrum M0 K +) a structure at the threshold region with a mass ∼1810 MeV and a distinct X(2000) peak with M= 1989 ± 6 MeV and γ= 91 ± 20 MeV are observed. Unusual features of the massive X(2000) state (narrow decay width, anomalously large branching ratio for the decay channel with strange particle emission) make it a serious candidate for cryptoexotic pentaquark baryon with hidden strangeness |qqqsˉs>. We also present new results on the narrow threshold structure X(1810) with M= 1807 ± 7 MeV and γ= 62 ± 19 MeV which is produced in the region of very small P 2 T < 0.01 GeV2. The possibility of the Coulomb production mechanism for X(1810) is discussed. Received: 28 April 1999

   The crystal structure of the title compound, [Fe(Im)6]Cl2·4H2O, (Im=imidazole) was determined by X-ray analysis. The crystal structure consists of Fe(Im)62+ cation, two Cl- anions and four non-coordinated water molecules. It crystallizes in the triclinic system, space group P1, with lattice parameters a=0.879 7(2) nm, b=0.906 8(2) nm, c=1.058 1(2) nm, α=75.35(3)°, β=83.20(3)°, γ=61.85(3)°, and Z=1; The Fe(Ⅱ) ion assumes centrosymmetric octahedron geometry with the FeN6 core. Six imidazole molecules are coordinated to each iron(Ⅱ) ion through its tertiary nitrogen atom. The bond distances of Fe-N are in range of 0.212 8(1) nm to 0.220 4(1) nm. In the solid state, [Fe(Im)6]2+, H2O molecules and chlorine anions form three dimensional hydrogen bonds network which stabilized the crystal structure. Elemental analysis and electronic spectrum are in agreement with the structural data. The thermal gravity (TG) data indicate that thermal decomposition of the title compound takes place in five steps. In these cases, the residue may be Fe. From the cyclic voltammogram measurement in EtOH/H2O, we know that electrode reaction was a quasi-reversible process. CCDC: 215335.

   Nano-sized HfO2, C and C/HfO2 powders obtained through hydrothermal process have been investigated by XRD, TEM and FTIR, and Different precursors, namely Hafnium(Ⅱ) oleate and Hafnium(Ⅱ) hydroxide derived from homogeneous precipitation method, have been chosen for the synthesis of nanometric HfO2 via hydrothermal process. The results indicate that using the former material as the precursor under identically hydrothermal process can yield finer HfO2 nanoparticles, compared to using the latter. Nano-sized Carbon of about 100 nm with square morphology and narrow size distribution can be obtained through hydrothermal reaction of sucrose solution at 200 ℃ for 6 h. The addition of as-synthesised Carbon nanoparticles into the hydrothermal process of HfO2 powder can produce C/HfO2 composite powders with core-shell structure.
