Bacteria Inhibitory Action of Peptides P753 and P359 in 2D and 3D Cell Cultures

Masuda J., Vig K., University of Hawaii at Manoa, US

The current study investigated two proprietary peptides, p359 and p753, for their antibacterial activity against Escherichia coli (E.Coli) and Staphylococcus aureus (S. aureus). Minimum Inhibitory Concentration (MIC) of bacteria for p359 and p753 was 50μg/mL [...]

A Green Plastic and Drop-in Transportation Fuels from Carbon Dioxide and Renewable Energy

Yu J., University of Hawaii at Manoa, US

With rapid technology progress and cost reduction, more electrical power is generated from renewable solar radiation and wind. Because of the intrinsic intermittency, however, the renewable power posts a great challenge to grid stability, and [...]

Internet-of-Things Hardware-in-the-Loop Simulation Testbed for Demand Response Ancillary Services

Thornton M., Smidt H., Schwarzer V., Motalleb M., Ghorbani R., University of Hawaii at Manoa, US

Demand response (DR) has proven to show capabilities of providing ancillary services (AS) to grid operators. Advances in high speed computing and the availability of widespread and efficient network infrastructure bring tools that were otherwise [...]

Charge Amplification of a Graphene-integrated-CMOS (GIC) RF Detector

Ordonez R.C., Hayashi C., Kamin N., de Andrade M.C., Garmire D., University of Hawaii at Manoa, US

A novel approach is demonstrated to characterize the charge amplification of mono-layered graphene as an integral part of a Complementary Metal Oxide Semiconductor Device (CMOS) under RF radiation. We have verified that charge carriers generated [...]

Infrared Sensor Interference Isolation for Low-Cost Three-Dimensional Anemometers

Hirano J., Garmire D., University of Hawaii at Manoa, US

The further integration of wind power generation into our power grids from residential and industrial building installations increases the need to gather high spatial resolution wind data. This results in a need for low-cost three-dimensional [...]

Self-Sufficient Smart-Grid Sensor Nodes and Architecture

Carland J., Oberbeck A., Umeda M., Cumming J., Wilkey T., Fripp M., Kuh A., Garmire D., University of Hawaii at Manoa, US

Energy systems of the future will be flexible and adaptive, capable of maximizing efficiency through sensing and predicting environmental and load conditions to effectively supply the right amount of power and mitigate grid issues. We [...]

Superhydrophobic and Superhydrophilic Nanocomposite Coatings for Preventing Microbial Adhesion on Liquid Food Contact Surface

Rungraeng N., Yoon S-H, Song W., Jun S., University of Hawaii at Manoa, US

Pathogenic microbes in biofilm matrix increase the potential of cross-contamination with processed food products, subsequently resulting in food borne disease outbreaks. Prevention of bacterial adhesion on food contact surfaces will have a massive impact in [...]

Infrared Sensor Interference Isolation for Low-Cost Three-Dimensional Anemometers

Hirano J., Garmire D., University of Hawaii at Manoa, US

The further integration of wind power generation into our power grids from residential and industrial building installations increases the need to gather high spatial resolution wind data. This results in a need for low-cost three-dimensional [...]

Self-Sustaining Meteorological Wireless Sensor Networks

Carland J., Oberbeck A., Umeda M., Cumming J., Wilkey T., Fripp M., Kuh A., Garmire D., University of Hawaii at Manoa, US

Existing electrical grid infrastructure designs cannot reliably handle large intermittent power production fluctuations. Providing an autonomous, self-powered, and easily deployable meteorological sensor network can provide the tools to help mitigate this issue. With proper data [...]

Clean Production of Bioplastic and Bio-oil from Solar Energy and Carbon Dioxide

Yu J., University of Hawaii at Manoa, US

Producing fuels and materials from solar energy and CO2 is a clean sustainable solution to the arising fossil energy consumption and CO2 emission. This paper presents a high intensity process that can run continuously at [...]
