This proposal suggests purchasing a cryogenic stage and controlled vitrification system for cryogenic electron microscopy. The system will be used to study the structure of nanometer sized ceramic and metallic particles precipitated or reduced inside the microdomains of vesicles. The production of nanosized particles in the microdomain reactors of vesicles and microemulsions represents and emerging technology with important applications. The purchase of the cryogenic system will easily allow for the rapid cooling of samples, thereby preserving the structure in its original state. Electron microscopic examination of these samples will provide information on the structure, kinetics and size distribution of the precipitated particles which will be of great use in tailoring process conditions to particle functionality.

该提案建议购买用于低温电子显微镜的低温载物台和受控玻璃化系统。 该系统将用于研究在囊泡微域内沉淀或还原的纳米陶瓷和金属颗粒的结构。 在囊泡和微乳液的微域反应器中生产纳米颗粒代表了具有重要应用的新兴技术。 购买低温系统将很容易实现样品的快速冷却，从而将结构保持在原始状态。 这些样品的电子显微镜检查将提供有关沉淀颗粒的结构、动力学和尺寸分布的信息，这对于根据颗粒功能调整工艺条件非常有用。
