TiN/GaN- Metal/Semiconductor Multilayers for Thermionic Energy Conversion Devices

Rawat V., Sands T.D., Purdue University, US

This work deals with investigation of metal/semiconductor nitrides for potential application as solid state thermionic energy converters. TiN/GaN multilayers were deposited on Sapphire and MgO substrate using reactive pulsed laser deposition. This is the first [...]

Investigation of the Conductance of Silicon Nanowire Biosensors Using the 2D Drift-diffusion Model

Damodaran S., Vadivelmurugan S., Do Q.T., Heitzinger C., Liu Y., Klimeck G., Purdue University, US

DNA-FETs are DNA sensors consisting of a semiconductor transducer and a functionalized surface. Their device structure is similar to a MOSFET, but the gate has been replaced by the functionalized surface. Since DNA-FETs allow direct [...]

Selective Heating Characterization of Nanoplate Devices for Simultaneous Sensing of Multiple Biomolecule Species at Ultra-low Concentrations

Elibol O.H., Reddy_Jr. B., Bashir R., Purdue University, US

We propose a novel scheme for the en masse fabrication and selective functionalization of field effect silicon nanoplate devices to enable the ultrasensitive, simultaneous and label-free detection of multiple biomolecular species in real time. The [...]

Theoretical Model for the Nanobundle Network Transistors Below and Above Percolation Limit

Pimparkar N., Guo J., Alam M.A., Purdue University, US

Recently, a lot of interest has been generated in the area of Macroelectronics with applications such as displays, chemical/biological sensors, photovoltaics and power electronics. Nanobundle network transistors (NBTs) have emerged as a viable, higher performance [...]

Synthesis and differential uptake of drug-decorated fluorescent nanoparticles by live cancer cells

Rozhkov R.V., Knudsen G.M., Sturgis J., Ribbe A.E., Robinson J.P., Davisson V.J., Purdue University, US

Design and applications of “smart” multivalent fluorescent probes based on semiconductor nanocrystals and anticancer drug molecules will be presented. Various polymer coating strategies have been employed to insure stability and define composition of nanoparticles. Next, [...]

Nano-Structured Biodegradable Ceramics for the Treatment of Osteoporosis

Balasundaram G., Webster T.J., Purdue University, US

There are a number of applications requiring bone-building agents. For example, osteoporosis is a disease resulting in weak bone. However, no current effective prevention and treatment methods exist for osteoporosis. For these reasons, in this [...]

Stem cell differentiation on nano-structured carbon surfaces

Ercan B., Price R., Webster T.J., Purdue University, US

The research is based on the differentiation of stem cells on carbonnanofibers.

Increased Osteoblast Adhesion on Nano-rough Anodized Titanium and CoCrMo

Yao C., Slamovicha E.B., Webster T.J., Purdue University, US

Titanium and cobalt-based alloys are two main groups of metallic materials widely used in orthopedic applications. One approach to improve biological properties of current titanium and CoCrMo implant is to mimic the nanostructures of natural [...]

Less Harmful Acidic Degradation of Poly(lactide-co-glycolide) Bone Tissue Engineering Scaffolds through Titania Nanoparticle Addition

Liu H., Slamovich E.B., Webster T.J., Purdue University, US

In the last ten years, biodegradable aliphatic polyesters, such as poly(lactide-co-glycolide) acid (PLGA), have attracted increasing attention for their use as scaffold materials in bone tissue engineering because their degradation products can be removed by [...]

Nano-structured Biodegradable Ceramics for the Prevention and Treatment of Bone Caner

Balasundaram G., Webster T.J., Purdue University, US

For people dying of some cancers such as breast and prostate, the spread of bone cancer is almost universal. Although current drug delivery systems have found a variety of uses in targeting certain forms of [...]
