FeSi nanoparticles were synthesized via thermal decomposition of iron pentacarbonyl in the solution of dioctyl ether, stabilizers oleic acid and oleylamine. The TEM images showed that FeSi nanoparticles had cubic shape, but it seemed that the composition was not uniform. According to the EDS results, the Fe:Si ratio of gray-uniform nanopaiticles was almost 1:1, and blacker FeSi nanoparticles contained more Fe atoms. Although FeSi didn't have uniform structure, it still could be proved that the incorporation of Fe and Si existed in a single nanoparticle. All possible structure, lattice, binding, morphology, surface condition would be discussed. These results indicated that perhaps FeSi2 was the main structure of the new products; however, due to incompletely combination and less synthesized time, it might still contain some part of Si and Fe structure. Besides, FeSi nanoparticles preserved the optical properties from Si atoms, but the PL intensity was much lower. The maxima PL peak appeared at 388 nm with the excitation at 300 nm. Their saturation magnetization, remanent magnetization and coercivity were measured by the SQUID, exhibiting their nearly superparamagnetic behavior.

利用热裂解系统可成功将研磨矽奈米粒子及五羰铁结合，制备出铁矽奈米粒子；从穿透式显微镜照片可知其粒子呈现立方体型态，但颜色深浅及组成不均，EDS结果则显示颜色均匀之粒子铁与矽之组成大致为1：1，颜色较深之粒子则含有较高量的铁元素；尽管组成比例并不统一，但单颗粒子同时含有矽与铁两种元素，初步说明铁矽奈米粒子之形成；进行多种结构与表面分析并探讨所有可能之键结、结构及表面元素后，推测铁矽奈米粒子可能以FeSi2之结构形成，并同时包含未重组完成的矽及铁之结构；利用PL分析得知铁矽奈米粒子确实保留矽之放光特性，并在300 nm激发光源下，於波长388 nm处有一最强放光特性峰，但整体发光效益不及研磨矽奈米粒子之结果；最后，利用超导量子干涉磁化仪量测其饱和磁化量、残留磁化量、与矫顽磁力，发现磁滞现象并不明显而几乎呈超顺磁性。

Mitochondrial 16S rRNA gene and COⅠ gene fragments were amplified and sequenced from 4 wild populations of Portunus trituberculatus. Respectively, 524bp and 658bp long partial gene fragments of the 16S rRNA gene and the COⅠ gene were obtained. A high percentage of A+T base composition in the two sequences was observed, which was similar to the results of studies on drosophila, shrimp, crab and other invertebrates.

At present, psychrometric method is widely used to measure the relative humidity in the flue-cured tobacco chamber. The author discovered that when the temperature in the flue-cured tobacco house was higher than 40℃, the relative humidity value obtained by psychrometric method was different from that measured by the criterion instrument. And the difference is greater when the temperature is higher and the relative humidity is lower.

Restoration of ODC expression in the HL60-ODC cells resulted in rescue of rottlerin-induced apoptosis of HL60 cells. Simultaneously, phosphothreonine-ODC of rottlerin-treated HL60-ODC cells was highly elevated comparing with HL60-pcDNA3 cells. Taken together, we suggested that rottlerin, a PKCd inhibitor, might decrease phosphothreonine-ODC to reduce both protein stability and enzyme activity of ornithine decarbooxylase and finally resulted in cell apoptosis.
