Compact Modeling of MEMS Contact Current upon Pull-In

Røst H.I., Clark J.V., Pister K.S.J., Auburn University, US

This work-in-progress presents a parameterizable compact model of a microelectromechanical system (MEMS) beam element that includes mechanical contact and electrical current flow upon gap closure. Quasistatic electromechanical simulation analyses include the initial onset of pull-in [...]

Wideband high-Q nonlinear resonance for MEMS

Clark J.V., Han Y., Abrol A., Zun Z., Auburn University, US

We examine high quality factor (Q) nonlinear wide- bandwidth resonance for microelectromechanical systems (MEMS) by mimicking high nonlinearity in stiffness by force feedback. The Q and bandwidth are usually thought of as being inversely proportional [...]

Low-Latency Analog Processors for Performance Control of MEMS

Han Y., Zhu Z., Abrol A., Clark J.V., Auburn University, US

Towards faster feedback response for controlling the performance of microelectromechanical systems (MEMS), we present the first use of the mathematical processing properties of bipolar junction transistors (BJT) for such control. This concerns a type of [...]

A More Accurate and Precise Method to Calibrate Atomic Force Microscope (AFM) Cantilevers

Clark J.V., Auburn University, US

This paper presents a method for using a calibrated microelectromechanical system (MEMS) device to calibrate an atomic force microscope (AFM) cantilever. Measure- ments of stiffness and deflection can be made with quantifiable uncertainty. The popular [...]

Precise Phage-navigating Metastatic Breast Cancer-targeted Paclitaxel-Micell Nanomedicines

Petrenko V.A., Torchilin V.P., Auburn University, US

Breast cancer is one of the most common cancers in the USA. Despite the increase of relative survival rate of women with breast cancer for the last decades, it is still low (~26%, 5 years) [...]

Self-navigating drug delivery nanovehicles driven by polyvalent multifunctional phages and their promiscuous proteins

Petrenko V.A., Gillespie J.W., Auburn University, US

Development of precision medicines acting specifically at the site of disease has been a long sought goal for the last century, starting from pioneering works of Paul Ehrlich, who suggested the concept of site-directed chemotherapeutics [...]

Molecular toolkits for engineering of self-navigating drug delivery vehicles

Gillespie J.W., Auburn University, US

Analysis of multi-thousand clone populations of the cancer cell-binding landscape phages and their multi-motif proteins using massively parallel sequencing techniques allowed the discovering of a variety of short motifs serving as elementary binding units during [...]

A Physics Based Approach to Compact Modeling of Noise in Modern Bipolar Transistors

Niu G., Auburn University, US

A physics based approach to compact modeling of bipolar transistor noise is described. Frequency dependent intrinsic base current noise, its correlation to intrinsic collector current noise, avalanche of intrinsic collector current noise entering the collector-base [...]

Controlling Alignment in Cellulose Nanocrystal Coatings

Haywood A.D., Ashurst R.W., Davis V.A., Auburn University, US

Investigations on the rheology and phase behavior of aqueous CNC dispersions have been used to develop processes for making CNC coatings with controlled properties. We report how the interplay between dispersion microstructure, shear, and drying [...]

Phase Behavior and Macroscopic Processing of Single-Walled Carbon Nanotube – Lysozyme Dispersions

Horn D.W., Davis V.A., Auburn University, US

Lysozyme (LSZ) facilitates the dispersion of single-walled carbon nanotubes (SWNT) while maintaining its’ antibacterial activity through macroscopic processing. The structural and enzymatic nature of LSZ makes possible the dispersion of SWNT for processing into macroscopic [...]
