Towards In-Vivo Radio Transmitting Nano-Robots

Dolev S., Narayanan R.P., Ben-Gurion University of the Negev, IL

An implementable design of a Nano Electro Mechani- cal (NEM) Carbon Nanotube (CNT) cantilever for com- munication in nanorobots is sketched in this brief sum- mary. Nano communication devices can provide future nanorobots with the [...]

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 Piezoresistive MEMS Memory Device Using a Buckled Beam

Yang J.A., Shuvra P.D., Lin J-T., Walsh K., McNamara S., Alphenaar B., University of Texas at Austin, US

Microelectronics and microelectromechanical systems (MEMS) have given rise to a large class of new de- vices, from ultra-miniature sensors for cell phones and automobiles to complex memory devices for computers. Recent research in memory devices [...]

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 [...]

An Airborne Gimballed Imaging System

Sun X., NextGen Imaging Technologies (NGIT), Inc., US

An airborne gimballed imaging system comprises an agile, accurate, efficient, and versatile gimbal machine. It drives a long range imaging sensor payload over wide roll, pitch, and yaw angular ranges. Together with an embedded instrument [...]

A Novel Colorimetric H2S Measurement for Environmental and Oil and Gas Applications

Skates V.W.L., van Hal R.E.G., Schlumberger-Doll Research, US

This paper provides a novel colorimetric method to measure hydrogen sulfide in water, air, natural gas and oil. A bismuth ion based reagent reacts with sulfide to form bismuth sulfide nanoparticles, causing the solution to [...]

Computational Fluid Dynamics Models for the Rational Design of Magnetic Microseparators – In Memory of Dr. Ed Furlani

, The Ohio State University, US

In this work, we report a numerical flow-focused study of bead magnetophoresis inside a continuous-flow microchannel in order to provide a detailed analysis of bead motion and its effect on fluid flow. Different Computational Fluid [...]

New Technologies for the Rapid Identification of Drug-Resistant Bacteria

Sauer-Budge A.F., Exponent and Boston University, US

The extensive use of antibiotics to treat infections, without first specifically identifying the underlying cause, has resulted in a strong natural selection for antibiotic resistant organisms. Conservative estimates from the CDC indicate that more than [...]

Mimicking Proximal Tubule Cell functioning for Artificial Kidney Applications

Sateesh1 J., Guha K., Dutta A., Sengupta P., Srinivasa Rao K., National Institute of Technology Silchar, IN

The importance for artificial organs development is ever increasing, especially for artificial kidney is needed by a vast number of people suffering from kidney failure. This paper presents a novel Bio-reactor technique by using the [...]

Human monocytes from fresh blood present strong magnetic characteristics; CTV analysis and magnetic susceptibility quantification

Kim J., Weigand M., Potgieter M., Walters N., Reategui E., Palmer A., Yazer M., Zborowski M., Chalmers J.J., The Ohio State University, US

The presence of iron in circulating monocytes is well known as they play essential roles in iron recycling. Also, the storage of this metal as well as its incorrect uptake and/or release are important data [...]
