Direct Oxygen Air Capture Using Pressure-Driven Ion Transport Membranes: Membrane Support Evaluation

Antwi S., Giwa A., Gobina E., Robert Gordon University, UK

In the chemical and medical fields, oxygen-enriched air plays a vital role in their operation. Commercial production of oxygen-enriched air is achieved by cryogenic distillation and pressure swing adsorption, respectively. The function of these two [...]

Optofluidic Temperature and Pressure Measurements with Fiber Bragg Gratings Embedded in Microfluidic Devices

Cooksey G.A., Wright J.D., Ahmed Z., National Institute of Standards and Technology, US

(INTRODUCTION) The integration of photonic sensors into microfluidic devices provides opportunities for dynamic measurement of chemical and physical properties of fluids in very small volumes. Microfluidic platforms provide sub-microliter control of fluid transport and mixing [...]

Transparent, Scalable, and Flexible Piezoelectric Pressure Sensors

Vishniakou S., UC San Diego, US

We present a pressure-sensitive ZnO thin-film transistor (TFT) as a potential technology for next-generation touchscreen. We discuss the properties of our devices and propose a structure that could be used to create transparent, scalable, and [...]

Impact of spray-casting height and pressure on durability and superhydrophobicity of nanocomposite coatings

Yeong Y.H., Davis A., Steele A., Loth E., Bayer I., De Combarieu G., Mechanical & Aerospace Engineering, University of Virginia, US

Recently, researchers introduced a new technique to fabricate superhydrophobic coatings by spray-casting polymer-nanoparticle suspensions using an air-atomizing nozzle. Upon thermosetting, the deposited polymer networks crosslink to form a durable, superhydrophobic nanocomposite coating. However, while the [...]

Design, Simulation, and Prototyping of an Impulse Turbine for Biomedical Applications

Cabra H., University of South Florida, US

An impulse bio-turbine with circular inlet/outlet area is presented. The system was designed using a scaled impulse macro turbine model, which was modified in size and shape to facilitate transformative integration in implantable biomedical devices [...]
