Entropy, Assembly and Novel Microscopy in Complex Fluids

这是一个凝聚态物理实验项目，旨在研究复杂流体环境中的粒子。复杂流体包括胶体悬浮液、乳液、聚合物溶液、膜以及它们的混合物。他们的研究动机是它们与细胞生物学的相关性，它们在广泛的商业产品中的应用，如油漆，颜料，机油，食品，化妆品，光子学，光刻，陶瓷和传感器技术。这些实验将（1）探索囊泡和DNA悬浮液中的熵力，（2）探测一系列悬浮液中的力场，（3）探测分子长度尺度上的扩散现象，以及（4）开发实现自组装胶体聚集体的方法。该项目为学生提供了极好的培训机会，使他们能够使用最先进的显微镜技术，在涉及广泛技术的领域进行基础研究。%这是一个实验凝聚态物理项目，旨在研究复杂流体环境中的粒子，如胶体悬浮液，乳液，聚合物溶液，膜及其混合物。这些材料出现在一系列背景下，如细胞生物学，油漆，颜料，机油，食品，化妆品，光子学，光刻，陶瓷和传感器技术。实验将探索粒子所经历的力和悬浮液的无序。另一个目标是利用这些信息来开发将导致微观和分子粒子的受控自组织的方法。该项目为学生提供了极好的培训机会，使他们能够使用最先进的显微镜技术，在与各种技术相关的领域进行基础研究。

This is an experimental condensed matter physics project to investigate the particles in complex fluid environments. Complex fluids include colloidal suspensions, emulsions, polymer solutions, membranes, and their mixtures. Their study is motivated by their relevance to cell biology, their use in a vast range of commercial products such as paints, pigments, motor oils, foods, cosmetics, photonics, lithography, ceramics and sensor technology. The experiments will (1) explore entropic forces in suspensions of vesicles and DNA, (2) probe force fields in a range of suspensions, (3) probe diffusion phenomena at the molecular length scale, and (4) develop methods to achieve self-assembling colloidal aggregates. The project offers excellent training opportunities for students in the use state-of-the art microscopy techniques to pursue fundamental studies in areas which also relate to a vast range of technologies.%%%This is an experimental condensed matter physics project to investigate the particles in complex fluid environments, such as colloidal suspensions, emulsions, polymer solutions, membranes, and their mixtures. These materials arise in a range of contexts such as cell biology, paints, pigments, motor oils, foods, cosmetics, photonics, lithography, ceramics and sensor technology. The experiments will explore the forces experienced by the particles and the disorder of the suspensions. Another objective is to use this information to develop methods which will lead to controlled self-organization of the microscopic and molecular particles. The project offers excellent training opportunities for students in the use state-of-the art microscopy techniques to pursue fundamental studies in areas which also relate to a vast range of technologies.
