Engineering Research Equipment: Laser Light Scattering Apparatus

CTS-9500156摘要将要购买的激光光散射仪，将主要用于各种无机纳米颗粒的生产和性能表征的项目。开发了一种新的水相胶体加工技术，该技术利用泡内反应来生产批量的纳米级无机颗粒。目的是更好地了解和控制颗粒形成技术，并了解纳米颗粒的性质。粒子的小尺寸可能会极大地改变电子波函数，导致“量子”尺寸效应。此外，在这个尺寸范围内的粒子主要包含“表面”原子(这些原子的键长和迁移率可能与块体中的原子不同)，导致对这些粒子的性质产生很大影响。该仪器还将用于表征用于细胞和质粒分离的磁性免疫吸收技术中的各种表面功能化磁性纳米团簇，获得磁性胶体制剂中准确的尺寸分布，以便正确解释同一样品上的中子和X射线散射数据，以及监测响应环境毒素镉的微管蛋白组装/分解的动力学。***

CTS-9500156 ABSTRACT A laser light scattering apparatus which will be purchase, and will be primarily utilized for a project on the production and characterization of the properties of a variety of inorganic nanoparticles. New aqueous colloidal processing technique that utilizes intravesicular reactions to produce batches of nanometer sized inorganic particles have been developed. The objectives are better understanding and controlling the particle formation technique, and understanding the properties of the nanoparticles. The small size of the particles could dramatically alter electron wave functions, leading to 'quantum' size effects. Furthermore, particles in this size range contain mostly 'surface' atoms (bond lengths and mobilities for these atoms can differ from that in bulk), leading to a large impact on the properties of these particles. This apparatus will also be used to characterize a variety of surface functionalized magnetic nanoclusters that are being used in a magnetic immunoabsorption technique for cell and plasmid separations, obtain accurate size distributions in magnetic colloidal preparations so that neutron and X-ray scattering data on the same sample can be interpreted properly, as well as monitor kinetics of tubulin assembly/disassembly in response to the environmental toxin cadmium. ***
