Multi-method analysis of multiwall carbon nanotube polymer nanocomposite after photodegradation

Petersen E.J., Lam T., Gorham J., Scott K., Long C., Sharma R., Sung L.P., Liddle J.A., Nguyen T., National Institute of Standards and Technology, US

Nanomaterials can be used as nanofillers to enhance the properties of polymeric materials. However, the effect of weathering on nanocomposites and the potential for nanomaterial release is not yet well known. This stems partly from [...]

Physical Modeling of MEMS Cantilever Beams and the Measurement of Stiction Force

Lam T., Darling R.B., University of Washington, US

A finite element model is combined with experimental data to extract the stiction force in MEMS cantilever beams. The model predicts cantilever behaviors both before and after snap-down has occurred. Experimental measurements of cantilevers have [...]

Modeling of Focused Ion Beam Trimming of Cantilever Beams

Lam T., Darling R.B., Univeristy of Washington, US

A finite element model of the cantilever beam is implemented to include a non-uniform thickness along its length, due to focused ion beam trimming. A quasi-static, iterative approach is used to calculate the cantilever profile [...]
