Understanding fluid flow across a surface is essential to a great number of technologies. For over one hundred years it has been assumed that the layer of fluid adjacent to the solid moves with the solid, this is known as the no-slip boundary condition. Recently direct force balance measurements of aqueous Newtonian solutions have indicated the presence of boundary slip. Using a newly developed nanorheology technique we will systematically investigate the conditions that control boundary slip. This information will be used to quantify, model and control boundary slip, progressing the fields of microfluidics, particle deposition, and colloid stability.

了解流体在表面上的流动对于许多技术来说都是至关重要的。一百多年来，人们一直假设与固体相邻的流体层随固体运动，这就是所谓的无滑移边界条件。最近，牛顿水溶液的直接力平衡测量表明边界滑移的存在。利用最新发展的纳米流变学技术，我们将系统地研究控制边界滑移的条件。这些信息将被用来量化、模拟和控制边界滑移，从而在微流体、颗粒沉积和胶体稳定性领域取得进展。
