Summary on Grant Application Form |
|
With the long term aim of providing high quality models of liquid behaviour on nanometric length scales, this project creates a collaboration between numerical specialists and precision metrologists to provide validated models of viscous damping of nanometre vibrations. This is of immediate interest to scientific instrument and precision mechanism design and forms the foundation for a broad range of applications, including physiological ones. Iterations between thereotical models and experimental data will provide a description of shear behaviour in the 1 to 10 nm regime which is poorly described by current models. The experimental investigation will examine with sub-nanometre sensitivity the dynamic behaviour in the presence of shear-films of various liquids of silicon monolithic elastic mechanisms. These have very low inherent damping and so allow direct inference of the liquid behaviour. The modelling will involve both molecular dynamics and continuum methods.
