CFD Analysis of the Generation and Manipulation of Ferrofluid Droplets

Karampelas I.H., Gómez-Pastora J., Amiri V., Tarn M.D., Bringas E., Iles A., Pamme N., Furlani E.P., Ortiz I., Flow Science Inc., US

In recent years, there has been a significant increase of droplet-based microfluidic systems. This is mostly due to the advantages that such systems present such as chemical and bio-compatibility, the ability to perform a variety [...]

Recirculating samples inside chambers using vacuum and centrifugal forces

Wang A., Koh D., Oh K.W., SMALL (Sensors and MicroActuators Learning Lab), Department of Electrical Engineering, The State University of New York at Buffalo, US

In this paper, a combination of vacuum and centrifugal forces was studied for recirculate samples inside the chambers. Detection low concentration samples, rare molecules such as cancer cells or certain proteins among large volume of [...]

Optimization of continuous-flow magnetic bioseparators through CFD numerical models

González-Fernández C., Gómez-Pastora J., Karampelas I.H., Bringas E., Ortiz I., The Ohio State University, US

Continuous flow bioseparators allow magnetic particles that are properly functionalized so that they get attached to dangerous pathogens. Specifically, the unique properties of magnetic particles enable their separation from blood, after fulfilling their role of [...]

Comprehensive Analysis of High Performing Electrochemical Biosensors and Their Applications: II, System Update

Leung S.W., Lai J.C.K., Idaho State University, US

We have mounted 5 different biocatalysts on a sensor platform to examine the performance of this electrochemical sensing system for the detection of different biomolecules/metabolites and environmental important molecules, with such we also compared how [...]

Resonance Tunneling in Concentric Quantum Rings

Nimmo J., North Carolina Central University, US

In the present work, the phenomenon known as resonance tunneling due to the presents of a magnetic field perpendicular to the surface of double concentric rings (DCQR) is presented. It has shown that in the [...]

Utilization of the Flexible Josephson Toroidal Junctions for Self- Powering 150K Super lattice Bits Having Non-volatile Memory Storage in One Device Assembly at Room Temperature

Chen E.T., Thornton J.T., Duh S-H, Kissinger P.T., Advanced Biomimetic Sensors, Inc., US

We report a self-powered multiple flexible Josephson junction-based toroidal (FJJT) array superconductive/mem-element super lattice bit (Sulbit) device for quantum computing with non-volatile memory and non-dissipation energy storage in room temperature in one device assembly developed. [...]

A New 1.5-Nanometer Titanium Treated Portland Cement

Monte S.J., Kenrich Petrochemicals, Inc., US

Patented modification of the surface of ordinary Portland cement with a 1.5-nanometer proprietary titanate coupling agent trade named Ken-React® KCM-3E produces a transformational Portland cement trade named Ken-Tec Portland cement allowing a 31% reduction in [...]

Sustainable Concrete: Enhancements and Challenges

Assi L., Carter K., Deaver E., Dekhn H., Ziehl P., University of South Carolina, US

Fly ash-based geopolymer concrete or alkali-activated fly ash-based concrete is a sustainable concrete that is not only reduced CO2 emissions, and also it utilizes waste materials such as fly ash, metakaolin, or blast furnace slag. [...]

Pilot Scale Demonstration & Independent Verification of Carbon Utilization Technologies for the NRG COSIA Carbon XPRIZE

Hansen T., Woolcock P., Leitch M., Extavour M., McCabe K., Southern Research, US

The NRG COSIA Carbon XPRIZE is a global competition to develop technologies for converting CO2 from power plants and industrial facilities into valuable products. The pilot scale demonstration required teams to operate at a 200 [...]

MCM-41 and Functionalized MCM-41 as Adsorbents to Remove Heavy Metals and Hardness from Contaminated Water and Groundwater

Leung S.W., Basnet N., Dejesus K., Lai J.C.K., Idaho State University, US

Mining operating and abandoned mines often have resulted in waste rock dumps and open pits that contain materials high in heavy metals and toxic elements. These contaminants are known to be present in groundwater, surface [...]
