丙环唑配合物的合成、缓释性能及生物活性研究

Five propiconazole(L) complexes (ML₂Cl₂, M=Zn(Ⅱ), Cu(Ⅱ), Co(Ⅱ); ML₄Cl₂, M=Ni(Ⅱ), Mn(Ⅱ)) were prepared and characterized by elemental analysis and IR. These complexes exhibited favorable controlled release property, it took 40 to 120 hours to release 85% amount of ligand in the water. The toxicity determination to Botrytis cinera, Rhizoctonia cerealis, Gibberella zeae, Fussrium moniliforme and Colletotrichum orbiculare indicated that the fungicidal activities of the complexes were better than that of the ligand except Mn-complex to Rhizoctonia cereali. The EC50 of Zn-propiconazole were 0.045 2～0.144 1 μg·mL^-1, Co- and Ni-propiconazole were 0.066 3～0.210 4 μg·mL^-1 and 0.183 9～0.340 7 μg·mL^-1, respectively, and Mn-propiconazole were only 0.353 6～0.538 0 μg·mL^-1. The growth regulation experiment to wheat seeding by dressing treating indicated that inhibiting activities of the complexes to root length and stem height were weaker than that of the ligand.     

纳米PbSnO3的制备及其燃烧催化性能的研究

Nanocomposite PbSnO₃was synthesized by coprecipitation method , and its phase evolution process was investigated. The particle size, crystal form, and phase of samples were determined with XRD, TEM and EDS. The catalytic actiyity of sample on the thermal decomposition of RDX was investigated by DSC. The results show that nanocomposite PbSnO₃with the diameter of 9 nm can be obtained by calcining at 600 ℃ for 2 h, which crystal is cubic (pyrochlore type). The catalytic actiyity of nanocomposite PbSnO₃on the thermal decomposition of RDX is much higher than that of normal PbSnO₃. The nanocomposite PbSnO₃can decrease the peak temperature of thermal decomposition of RDX from 240.1 ℃ to 236.5 ℃, and the decomposition enthalpy ΔH of RDX increases 722 J·g^-1 （about 70%）.

热谱重建法及其在热动力学研究中的应用

在热动力学研究中,大多数实验是在热导式热量计中进行的。由于量热系统的热惯性,记录得到的热谱会出现“失真”,为了正确方便地分析被研究过程的动力学性质,必须对所得热谱进行改造或重建。本文系统地提出了一种新的重建法,即热谱重建法。实验结果表明,该法可广泛应用于热动力学研究。
