CTS-9625468 Wirtz This is a grant to purchase a controlled-strain rheometer with rheo-optical capabilities to study the dynamics of complex fluids. This device is capable of making steady, transient and dynamic measurements. Mechanical measurements will be conducted simultaneously with rheo-optical measurements (i.e. dichroism and birefringence). the rheometer will compliment the experimental techniques currently used. The equipment will be used for a broad range of topics that include relating the tunable microstructure with the viscoelastic properties of magnetic colloidal suspensions, comparing the viscoelastic properties of vesicles as measured by rheometry and light scattering techniques and the study of the rheological properties of a wide range of fluids including sheared polyelectrolyte solutions, highly strained lubricants and surfactant-polymer mixtures.

CTS-9625468维尔茨 这是一笔赠款，用于购买一台具有流变光学功能的可控应变流变仪，以研究复杂流体的动力学。 该装置能够进行稳态、瞬态和动态测量。 机械测量将与流变光学测量（即二向色性和双折射）同时进行。 流变仪将补充目前使用的实验技术。 该设备将被用于广泛的主题，其中包括与磁性胶体悬浮液的粘弹性性能的可调微结构，比较通过流变和光散射技术测量的囊泡的粘弹性性能和流变性能的研究范围广泛的流体，包括剪切的水溶液，高度应变的润滑剂和表面活性剂聚合物的混合物。
