III-nitrides represent an important semiconductor material system for both optoelectronic and power electronic device applications. Advantages for III-nitrides include high electron saturation velocity, high critical electric field, high radiation resistance and decent thermal performance. Therefo…

As the world continues to grow and industrialize, the need for safe and efficient power is paramount. Currently, in nuclear fission reactors, there are Local Power Range Monitors (LPRM). They are ion chambers that contain fissile material. The electric current between their anode and cathode is mo…

Dried blood spots on paper substrates offer a facile sample collection, storage, and transportation approach for biofluids. However, variable diffusion, volcanic effects, analyte instability, and difficulty in recovering samples from paper plague this method, lowering confidence in analyte quantif…

The Need Numerous cancer cells are capable of migration, resulting in metastasis of distinct organs and tissues from where the cancer first arose. Migrating cancer cells are known to directionally respond to applied electric fields, a phenomenon called electrotaxis, as well as topological cues prov…

Electrical Capacitance Volume Tomography (ECVT) is a non-invasive image reconstruction that provides volumetric images of a material. An ECVT system is generally comprised of a sensor, data acquisition system, computer system, and software for reconstruction of the 3D image. Capacitance data colle…

Atomic Force Microscopy (AFM) was first used to characterize properties of a sample, including physical, material, electromechanical and chemical properties. For most of these multi-physical characterization schemes, an AFM tip scans over a sample while the tip is in contact with the surface. At t…

Power electronic converters need a certain type of auxiliary power unit to provide electric power to their controllers, gate-driving circuits and/or sensors. For power electronic converters used in high voltage systems, the auxiliary power unit is difficult to design and fabricate due to massive e…

Nitric oxide plays an important role in the biological system of living organisms. Nitiric oxide has been shown to regulate and mediate numerous processes in the nervous, immune, and cardiovascular systems by transmitting signals throughout the body. It is used within the cardiovascular system to …

The directional movement of biological cells in the presence of an applied electric field is known as galvanotaxis or electrotaxis. The majority of experiments related to galvanotaxis over the past two centuries have involved steady electric fields applied via electrodes placed in contact with a m…
