Surface Characterization of a Direct, Label-Free Piezoelectric Immunosensor Platform

Papadopoulou-Bouraoui A., Lejeune M., Barrero-Moreno J., Valsesia A., Manso M., Gilliland D., Ceccone G., Rossi F., European Commission - JRC, IT

During this study the QCM (Quartz Crystal Microbalance) crystal surface was functionalized in order to provide active amino groups, and serve as an active platform for antibody immobilization and the development of direct, label-free immunosensors. [...]

Nanobiodevices Integrating Biomolecular Motors

Ramachandran S., Wu D., Nitta T., Tucker R., Phillips A., Hess H., University of Washington, US

Biomolecular motors, such as the motor protein kinesin, can serve as force-generating modules in hybrid nanodevices. We will present recent progress in utilizing these motors for nanoscale transport of target reagents and discuss applications, such [...]

Mechanical Parameter Extraction of Thin-Film Coated Materials

Li Y., Tseng K.K., Vanderbilt University, US

Materials coated with thin-films have become popular in many advanced applications. The thin layer of high-strength coating can improve the performance of the material. However, challenges arise when characterizing or extracting mechanical parameters for this [...]

Phase Identification and Elastic Property of Blend Copolymer Characterized by Force Modulation Microscopy and Force-Distance Curve

Kang B., Lee J.S., Pham L., Sung C., University of Massachusetts-Lowell, US

The technique of polymer blending has been used to create new types of polymers with desirable properties in the past decade. Force Modulation Microscopy (FMM) provides a local contrast due to the local elasticity difference [...]

DOE Optimization and Phase Morphology of Electrospun Nanofibers of PANI/PMMA Blends

Desai K., Sung C., University of Massachusetts-Lowell, US

Electrospinning is a process by which sub-micron polymer fibers can be produced using an electrostatically driven jet of polymer solution. The fibers are collected as a non-woven mat or membrane with high surface area to [...]

Uniform Polycarbonate Nanofibers Produced By Electrospinning

Kattamuri N., Sung C., University of Massachusetts, US

In the present work electrospinning of polycarbonate has been performed to produce nanofibers.Parameters like concentration,voltage,flow rate and distances were varied and an optimum condition of all the parameters was achieved to generate uniform ,smooth nanofibers [...]

MEMS Resonator Tuning using Focused Ion Beam Platinum Deposition

Enderling S., Jiang L., Ross A.W.S., Bond S., Hedley J., Harris A.J., Burdess J.S., Cheung R., Zorman C.A., Mehregany M., Walton A.J., University of Edinburgh, UK

This paper presents a novel post-fabrication tuning method which changes the resonant frequency of micromechanical beam resonators using Focused Ion Beam (FIB) deposition and removal of platinum. Tuning was achieved by depositing platinum on a [...]

Elasto-plastic Properties of Electroplated and Polycrystalline Nickel using Numerical Modelling of the Nanoindentation Test Coupled with an Inverse Method

Qasmi M., Delobelle P., Richard F., Université de Franche-Comté, FR

The aim of this paper is a wide investigation of the nano scale of the elastoplastic properties of electroplated Nickel, which is extensively used in the LIGA techniques and polycrystalline hardened and annealed Nickel with [...]

Burned Metal Phenomenon: A Study of Critical Factors and Their Effects on IC Devices during Parallel Lapping

Batteate P., Liao J.Y., Nvidia, US

Parallel lapping is widely employed in destructive physical analysis on semiconductor integrated circuits, to reveal defects isolated by electrical failure analysis tools and techniques. A clean sample surface is critical so that the analysts can [...]
