Design, Simulation, and Prototyping of an Impulse Turbine for Biomedical Applications

Cabra H., University of South Florida, US

An impulse bio-turbine with circular inlet/outlet area is presented. The system was designed using a scaled impulse macro turbine model, which was modified in size and shape to facilitate transformative integration in implantable biomedical devices [...]

Long-Range Interactions in Quasi-One Dimensional Cylindrical Structures

Tatur K., Woods L.M., University of South Florida, US

Casimir forces originating from vacuum fluctuations of the electromagnetic fields are of increasing importance in many scientific and technological areas. The manifestations of these long-range forces at the nanoscale have led to the need of [...]

Catalyst assisted zinc oxide nanowires for gas sensors

Joshi R.K., Kumar A., University of South Florida, US

We present the room temperature detection of 100 ppm carbon monoxide using metal ( Pd and Au) decorated Zinc Oxide (ZnO) nanowires. Zin oxide nanowires were grown via Vapor Liquid Solid method whreas the palladium [...]

Electronic structure of single wall carbon nanotubes under transverse external electric fields, radial deformations and defects

Shtogun Y.V., Woods L.M., University of South Florida, US

Our tight-binding results show that energy gap modulations of radially deformed carbon nanotubes by external electric field can be achieved using various field amplitudes and field orientations, and deformation strengths, thus proving many more capabilities [...]

Multiphysics Modeling and Simulation for a MEMS Thermal-Mechanical Switch

Bumgarner J., Langebrake L., Onishi S., Popuri R., Wang W., University of South Florida, US

This paper presents the results of finite element analysis (FEA) modeling and simulation including thermal-electric-structural multiphysics contact phenomenon for a MEMS thermal-mechanical DC switch. The parametric model can be used for design optimizations.The switch consists [...]

Glycosaminoglycan model glass substrates and cancer cell interactions

Dalton W.S., Matthews G., Meads M.B., Peramo A., Wright G., University of South Florida, US

The static adhesion of three cancer cell lines to surfaces functionalized with glycosaminoglycans was performed and the possible involvement of heparanase in this process was analyzed. Four different glycosaminoglycans (heparan sulfate, chondroitin sulfate A, chondroitin [...]

Bayesian Modeling of Quantum-Dot Cellular Automata Circuits

Bhanja S., Srivastava S.N., University of South Florida, US

The goal of this work is to develop a fast, Bayesian Probabilistic Computing model [1], [2] that exploits the induced causality of clocking to arrive at a model with the minimum possible complexity. The probabilities [...]

Environmentally Friendly Pathways for Synthesis of Titanium Dioxide Nano-particles

Li H., Sunol A.K., Sunol S.G., University of South Florida, US

Titanium Dioxide is an important catalyst for oxidation of hazardous compounds in air and water particularly for photo-catalysis. Although it is traditionally used for photo-catalysis with UV light, when its energy band gap is reduced, [...]

Photo-Enhanced Luminescence in Bio-conjugated Quantum Dots for Ovarian Cancer Biomarkers

Dybiec M., Korsunska N.E., Ostapenko S., Sellers T., Zajac A., Zhukov P., Zhukov T., University of South Florida, US

Ovarian cancer is the most lethal gynecologic malignancy. This largely reflects the fact that approximately 75% of cases are detected at advanced stages of disease, when cure is unlikely. In contrast, 5-year survival for patients [...]

A Novel Fabrication Technique of Cylindrical Ion Traps using Low Temperature Co-fired Ceramic Tapes

Bhansali S., Chaudhary A., Short R.T., van Amerom F.H.W., University of South Florida, US

This work concentrates on a novel technique for the fabrication of miniaturized cylindrical ion trap structures (CIT) to be used as replacements of commercial hyperbolic structure ion trap mass spectrometers. Low temperature co-fired ceramic (LTCC) [...]
