Vibration Assisted Nano Mechanical Machining through Atomic Force Microscope

The objectives of this proposed research are the development of a piezoelectric actuator system to assist nano machining by minimizing forces and the generation of nano-patterns to achieve the desired surface characteristics. The objectives shape the comprehensive technologies required to achieve flexibility, productivity and accuracy in manufacturing miniature systems through a judicious combination of experimental and analytical analysis.

A study of free surface electrospinning to enhance and optimize the nanofibre production process

Free Surface Electrospinning (FSE) is a novel process capable of producing non-woven webs of continuous nanofibres with controlled morphology and size from polymer solutions with the application of high electric fields. This novel scheme which was based on a rotating cylinder-solution feeding system is capable of producing nanofibres at a reasonable rate with compared to the conventional capillary schemes. We propose to further investigate and optimize the scheme for the use of wide range of applications in industry.

Hierarchical Heat Transfer Modelling in High-End Electronic Devices

One of the main challenges in the development of nano-scale devices is that the conventional physical relations and techniques, which have been used for modelling thermal problems at macro-scales, are no longer valid at these small scales.  In this project, we are developing a new hierarchial methodology to be applied to thermal management issues for nano-scale devices.  The impact of elecromigration in a joule heating form will also be explored.  Devices with nano-scale feature sizes are currently employed in high-end electronic systems.  In this method, we include the atomistic level effe

Design Tools for Next Generation of Microelectronics Cooling Solutions-Characterization, Modeling and Optimization.

There is an increasing trend towards miniaturization in the microelectronics industry which increases the power density and thus heat generated from these devices. Consequently, one key factor limiting reliability and higher performance of electronic devices is the heat removal, to maintain the device below its maximum operating temperature. This indicates the importance of devising efficient cooling strategies to meet the demands of the electronics sectors. The goal of this program is to develop and implement state-of-the-art cooling solutions for Analytic Systems’ products.

Optimization of Plastic Scintillator Thicknesses for Beta Gamma Detection

Because radiation is so prevalent in modern technology it is important to have instruments that will measure radiation. Instruments that measure exposure rate or the intensity of radiation at a location are called radiation detectors. Most of the detectors used to measure ionizing radiation (such as alpha, beta, and gamma radiation) are based on the ability of the radiation to ionize materials or to excite atoms within materials. Most of the radiation detectors used in radiation measurements will measure only one type of radiation at a time (for example, only beta or only gamma radiation).

Optimization of Optical Signal in Microarrays: Predicting properties of polycrystalline ZnO coatings

This project addresses an important need for more reliable diagnostics and health care testing. DNA microarray technology coupled with PCR has enabled a dramatic improvement in high]throughput clinical diagnostics, with analogous advances from other biomolecular and chemical microarrays in areas of metabolomics, proteomics, etc. There is still room for improvement, however, in boosting signal from low]replicate samples and reducing false positives from either fluorescence noise or lower fidelity hybridization or coupling.
