Analytical and Numerical Analysis of Oval-Shaped Composite Beam

A. K. Parkhe [1], R. B. Kapurkar [1], P. M. Pawar [1],
[1] SVERI's College of Engineering, Pandharpur, Maharashtra, India

In this poster, I have given a brief introduction on the composite beam which was used for the analysis. I have added theoretical formulae which were used for the analytical study of composite beam. The boundary conditions applied to the composite beam is also shown. When load is applied ... En savoir plus

Thermal-Optical Modeling of a Signal Enhancement Approach for Paper-Based Diagnostics

D. Gasperino [1]
[1] Intellectual Ventures Laboratory, Bellevue, WA, USA

INTRODUCTION: Point of care diagnostics aimed at low-resource settings need to be relatively simple, robust and low-cost. The most commonly-used diagnostic platform in these settings is the lateral flow assay (LFA). LFAs are paper-based immunoassays designed to perform on-strip binding ... En savoir plus

[1] Tezpur University, Sonitpur, Assam, India

Present work demonstrates a detail simulation results on enhanced generation of localized surface plasmon resonance (LSPR) field condition in a periodically varying height metal nano-pillars. Periodically varying height metal nanopillar provides enhanced LSPR field conditions than ... En savoir plus

Air Damping Simulation of MEMS Torsional Paddle

N. Mahmoodi[1], C. J. Anthony[1]
[1]University of Birmingham, Birmingham, UK

Viscous damping has a significant effect on dynamic performance of the resonators operating within fluid. This work is aimed to find the viscous damping for MEMS torsional paddle operating in air. Interaction of moving structure with the fluid requires a complicated and challenging ... En savoir plus

Towards the Modeling of Microgalvanic Corrosion in Aluminum Alloys: the Choice of Boundary Conditions

N. Murer[1], N. Missert[2], and R. Bucchheit[1]

[1]Fontana Corrosion Center, Ohio State University, Columbus, OH, USA
[2]Sandia National Laboratories, Albuquerque, NM, USA

Aluminum alloys in near-neutral, mildly aggressive solutions, undergo damage accumulation during corrosion, mostly due to the presence of micrometer-sized constituent intermetallic particles (IMP) that create a microstructural discontinuity at which localized corrosion occurs. The ... En savoir plus

Electrochemical Characterization of the Microband Graphite Electrodes

A. V. Volkov [1], A. N. Sekretaryova [2], I. V. Zozoulenko [1], A. P. F. Turner [2], M. Yu. Vagin [2], M. Eriksson [2]
[1] Laboratory of Organic Electronics, Department of Science and Technology, Linköping University, Norrköping, Sweden
[2] Department of Physics, Chemistry and Biology, Linköping University, Linköping, Sweden

The microband design of microelectrodes is a cost-effective and easily-fabricated compromise combining convergent mass transport, due to microscale width as a critical dimension, and high output currents due to the macroscopic length. Among the various techniques available for microband ... En savoir plus

Ultrasensitive Mass Sensing Through Coupled Microelectromechanical Resonator Arrays

A. R. Hambarde [1], R. M. Patrikar [1],
[1] Visvesvaraya National Institute of Technology, Nagpur, Maharashtra, India

Microelectromechanical coupled resonating arrays are being used for detecting biological and chemical analytes through mass sensing. Such arrays of perfectly identical resonators can be considered as periodic, ordered, non-localized systems. The change in the eigen parameters of the ... En savoir plus

Effect of a High Frequency Field on the Electric Double Layer Surrounding a Biomolecule in a Fluid

M. Riou[1], C. Maedler[1], S. Erramilli[1], P. Mohanty[1]
[1]Boston University, Boston, MA, USA

Biosensors based on silicon nanowires are of great interest for ultrasensitive biomolecular recognition of disease specific markers for early stage diagnosis [1].
