Fluorescence Microscopy of Nanoscale Silver Oxide Thin Films

The experimental conditions for photoactivated intermittent fluorescence from nanoscale silver oxide were studied with fluorescence microscopy.Strong fluorescence was observed from the Ag2O particles with size of 10-20nm excited with both blue and green light .We observed the saturation of Photoexcitation with blue light and explained the experimental results using the model of agglomeration of silver atoms to form small clusters and the fluorescence of Ag2 and Ag3 clusters.     

甲烷部分氧化反应机理的键级守恒研究

用键级守恒－Ｍｏｒｓｅ势方法研究了甲烷部分氧化制合成气的反应机理，以Ｎｉ晶面为模型催化剂，应用ＢＯＣ－ＭＰ方法计算了甲烷在有氧与无氧参与下的解离反应及ＣＯ和ＣＯ２生成反应中各基元反应的活化能垒和反应热焓。计算结果表明，无表面氧参与下的ＣＨ４直接解离途径更可能发生；由ＣＨ（ｓ）生成ＣＯ比由Ｃ（ｓ）更易进行。

毫微克DNA—DAPI复合物荧光法测定的研究

DAPI（4－6＝脒基－2－苯基吲哚）是检测微量DNA的专一性荧光染料，其最高灵敏度为0．1ng/ml,DNA浓度由微微克向毫微克增大时，峰位红移10－20nm。DNA浓度在1－100ug/ml时，DAPI的适宜浓度范围为30－100ng/ml。     

SYNTHESIS OF MACROPOROUS COPOLYMER OF VCA AND DVB

The reactivity ratios of vinyl acetate(VAc) and divinyl benzene (DVB) were calculated from the Q and e values.The possibility of the copolymerization of these two monomers was predicted and the copolymerization was carried out by suspension polymerization technique in the presence of pore producing agent (toluene and gasoine).The relative ratio of acetoxy group and benzene ring in the copolymer were monitored by IR measurement during the polymerization.The variation of pore properties,such as spectific surface area,porosity and average pore diameter,with polymerization time were determined.The copolymers at various polymerization time were alcoholyzed and thus the variation of the hydroxyl group content with polymerization time was studied.
