项目摘要

We at first constructed a vacuum apparatus in which we can prepare multiply twinned particles (MTP) by deposition. Using this apparatus we made MTP micelle as follows. NaCL of 1,500A were at first deposited on a spherical glass vessel which maintained at 350ﾟC.On this surface, we deposited Au of 100A and NaCL of 1000A alternately and MTPs were buried in the deposited NaCL film. A thiols solution (M beta-mercaptopropionic acid : HSCH_2CH_2COOH,10^<-3>mol/1) was poured into the glass vessel and MTP were covered by thiols molecules, resulting in the MTP micells. We called this moleculer assembly "uni-particles".A drop of the MTP micelle solution was put on a mesh of electron microscope, dried and observed by transmission electron microscope, electron diffraction and acanning electron microscope. Almost of the Au particles were MTPs with average diameter of about 70A.We observed a new phenomenon that when electron beam was concentrated on the sample, some of the MTP micelles started to move to approach in each other and they merged to one particle after 3-5 minutes. We analyzed the composition of the MTP micelles by total reflection angle X-ray spectroscopy (TRAXS) and detected Au and S signals and confirmed the MTP micelle structure. We studied the MTP micelle by electron spectroscopy (UPS,MIES), and obeseved that thiolate molecules of carboxyl acid are stretching toward outside of MTP.Furthermore, we studied the MTP micelle by nucler magnetic resonance (NMR) and confirmed the MTP micelle structure. We have pinted out that the apprication of the MTP micells to metal painting maaterial, column-chromatography, catalytic agent, electronic device, cosmetics etc.

我们首先构建了一个真空设备，在该设备中我们可以通过沉积来准备乘双颗粒（MTP）。使用此设备，我们将MTP胶束如下。 NaCl的1,500A首先沉积在球形玻璃容器上，该玻璃容器保持在350°C.在该表面上，我们沉积了100a的AU，NaCl为1000a，另一种是NaCl的NaCl膜，并在沉积的NaCl膜中建造了MTP。将硫醇溶液（Mβ-羟基丙酸：HSCH_2CH_2COOH，10^<-3> mol/1）放入玻璃容器中，并被硫醇分子覆盖，导致MTP胶束。我们称该分子组件为“ Uni Practicle”。将MTP胶束溶液的下降放在电子显微镜的网格上，并通过透射电子显微镜，电子衍射和Acanning Electron显微镜干燥并观察到。几乎平均直径约为70a的MTP的几乎是MTP。我们观察到一种新现象，即当电子束集中在样品上时，一些MTP胶束开始彼此移动，并且在3-5分钟后它们合并为一个粒子。我们通过总反射角X射线光谱（TRAXS）分析了MTP胶束的组成，并检测到AU和S信号，并确认了MTP胶束结构。我们通过电子光谱学（UPS，MIES）研究了MTP胶束，并肥胖认为羧酸的硫醇酸盐分子伸向MTP的外部，我们研究了Nucler磁共振（NMR）MTP胶束，并确认了MTP Micelle结构。我们已经挑出了MTP胶束在金属绘画材料，色谱，催化剂，电子设备，化妆品等中的应用。
