Proton irradiation Of GaO Schottky diodes and NiO/GaO heterojunctions.

p-NiO/n-GaO heterojunction (HJ) diodes exhibit much larger changes in their properties upon 1.1 MeV proton irradiation than Schottky diodes (SDs) prepared on the same material. In p-NiO/GaO HJ diodes, the narrow region adjacent to the HJ boundary is found to contain a high density of relatively deep centers with levels near E-0.

High sensitivity saliva-based biosensor in detection of breast cancer biomarkers: HER2 and CA15-3.

The prevalence of breast cancer in women underscores the urgent need for innovative and efficient detection methods. This study addresses this imperative by harnessing salivary biomarkers, offering a noninvasive and accessible means of identifying breast cancer. In this study, commercially available disposable based strips similar to the commonly used glucose detection strips were utilized and functionalized to detect breast cancer with biomarkers of HER2 and CA15-3.

Electrical and Recombination Properties of Polar Orthorhombic κ-GaO Films Prepared by Halide Vapor Phase Epitaxy.

In this study, the structural and electrical properties of orthorhombic κ-GaO films prepared using Halide Vapor Phase Epitaxy (HVPE) on AlN/Si and GaN/sapphire templates were studied. For κ-GaO/AlN/Si structures, the formation of two-dimensional hole layers in the GaO was studied and, based on theoretical calculations, was explained by the impact of the difference in the spontaneous polarizations of κ-GaO and AlN. Structural studies indicated that in the thickest κ-GaO/GaN/sapphire layer used, the formation of rotational nanodomains was suppressed.

High sensitivity CIP2A detection for oral cancer using a rapid transistor-based biosensor module.

Oral squamous cell carcinoma (OSCC) is one of the most common lip and oral cavity cancer types. It requires early detection via various medical technologies to improve the survival rate. While most detection techniques for OSCC require testing in a centralized lab to confirm cancer type, a point of care detection technique is preferred for on-site use and quick result readout.

High volume UV LED performance testing.

There is increasing interest in deep UV Light-Emitting Diodes (LEDs) for applications in water purification, virus inactivation, sterilization, bioagent detection, and UV curing, as well as charge management control in the Laser Interferometer Space Antenna (LISA), which will be the first gravitational wave detector in space. To fully understand the current state of commercial UV LEDs and assess their performance for use on LISA, large numbers of UV LEDs need to be tested across a range of temperatures while operating in air or in a vacuum. We describe a new hardware system designed to accommodate a high volume of UV LED performance tests and present the performance testing results from over 200 UV LEDs with wavelengths in the 250 nm range.
