Gas Phase Nanoparticle Integration

Barry C.R., Jacobs H.O., University of Minnesota, US

We report on two gas phase nanoparticle integration processes to assemble nanoparticles and other nanomaterials onto desired areas on a substrate. We expect these processes to work with any material that can be charged including [...]

N-channel Single Crystal Si Nanoparticle Schottky Barrier Transistor

Song S.H., Ding Y., Kortshagen U., Bapat A., Campbell S.A., University of Minnesota, US

A novel process has been developed by when large (~40 nm) cubic single crystals of silicon can be produced at high rates. In a previous paper we demonstrated that these particles can be used to [...]

Nonlinear Response in Nanoshear Modulation Force Microscopy: Fourier Analysis

Haugstad G., University of Minnesota, US

Oscillatory methods in scanning probe microscopy have enabled nanoscale tribology and rheology investigations on polymeric systems. Among these methods, shear modulation force microscopy has been used to probe phenomena such as the stick-to-slide transition, time-delayed [...]

Probing the Morphology and Tribo-Response of Nanostructured Fluid Films for Personal Care Applications

Haugstad G., Avery A., University of Minnesota, US

We present a methodology for interrogating silicone-based polymer-surfactant complex films a few nanometers in thickness. The films include 2D regions of liquid character interspersed in regions of solid character. Images are radically different in a [...]

A Modeling Approach based on Laminated Plate Theory to Design Microbeams

Mantell S.C., Longmire E., Wolters D., University of Minnesota, US

MEMs microbeams consist of many thin material layers. This thin layered structure is very similar to that of laminated composite plates in which thin layers of fiber reinforced plastic are stacked and cured. Both the [...]

MEMS for Drug Screening Applications

Zhou J., Zurn S., Markus D., Mantell S.C., Polla D., Smith G., University of Minnesota, US

MEMs offer a quick, low cost method for screening new drugs. In this MEMs application, microbeams were designed such that an affinity between the beam surface (coated with a biomolecule) and a second biomolecule (simulating [...]

Design, Fabrication and Experimental-Numerical Study of PZT Sensors

Arik M., Zurnx S.M., Yigit K.S., Bar-Cohen A., University of Minnesota, US

MEMS micropumps, based on PZT membranes have been designed and fabricated at the Microtechnology Laboratory of the University of Minnesota for use in fluid flow control, and as chemical and pressure sensors. Design, fabrication and [...]

Design, Simulation and Fabrication of a Bridge Structure Microtransducer

Zanga M., Zurn S.M., Polla D.L., Nelson B.J., Robbins W.P., University of Minnesota, US

ANSYS simulation of a variety of microtransducers was performed. The results indicate that a bridge structure is an optimal design for a microtransducer. Simulation of a bridge structure PZT thin film microtransducer was verified by [...]
