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 [...]

First principle study of Germanium and Selenium doped monolayer black phosphorus

Tejaswi Issarapu C.S., Junghare R.C., Patil G.C., Visvesvaraya National Institute of Technology Nagpur, IN

Within the framework of density functional theory, we investigate the effects of dopants germanium and selenium on the electronic properties of monolayer black phosphorus. Dopants are introduced in two possible chemisorption and substitution configuration. Findings [...]

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 [...]

In this paper, a parasitic capacitance model for a finite single three-dimensional (3-D) wire above an infinite plate in the nano-scale 3-D integrated circuit application is developed based on electric field decomposition (EFD). The capacitance [...]

Numerical Method to Simulate GFET Terahertz Wave Detection

Ma X., He J., He X., Li C., He J., He X., Jun P., Hu G., Ren Y., Wang X., SoC Key Laboratory, Peking University Shenzhen Institute and PKU-HKUST Shenzhen-Hong Kong Institution, CN

A numerical method to simulate THz wave generation and detection of the graphene base field effect transistor (GFET) is developed in this paper. It is derived directly from the hydrodynamic equations and implemented in Matlab [...]

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 [...]

Ab-initio tight binding Hamiltonian generation for 1D and 2D MoS2 based Devices

Junghare R.C., Patil G.C., Visvesvaraya National Institute of Technology Nagpur, IN

In this work electronic structure of mono layer MoS2 is analysed by using density functional theory (DFT) and wannierised tight binding approach. The DFT analysis is performed by open source tool Quantum ESPRESSO and wannierised [...]
