Galilean Invariant Viscosity Term for an Athermal Integer Lattice Boltzmann Automaton in three Dimensions

Geier M.C., Greiner A., Korvink J.G., IMTEK, Albert Ludwigs University Freiburg im Breisgau, DE

The athermal lattice Boltzmann automata (LBA) are promising replacements for Navier Stokes solvers in computational fluid dynamics (CFD). They are inherently parallel, scale exactly linear with the number of computational elements and can be applied [...]

A Low Cost Polymer Based Piezo-Actuated Micropump for Drug Delivery System

Liu H., Tay A.A.O., Wan S.Y.M., Lim G.C., Institute of Materials Research & Engineering, SG

This paper presents the design, realization and simulation of a novel polymer based check-valve micropump actuated by piezoelectric disc. Comparing with silicon substrate, polymer materials have such advantages as flexibility, chemical and biological compatibility, 3D [...]

Numerical Visualization and Quantification of Chaotic Mixing for Micromixers

Kang T.G., Kwon T.H., Pohang University of Science and Technology, KR

We present a systematic way of visualization and quantification of mixing in chaotic micromixers with a periodic mixing protocol. We name it colored particle tracking method, which consists of three steps. One is flow analysis [...]

Application of Local Radial Basis Function-based Differential Quadrature Method in Micro Flows

Xu D., Ding H., Shu C., Agency for Science Technology and Research, SG

Numerical simulation of flows in micro geometry is one of the most appealing fields in computational fluid dynamics due to the advent of MEMS. In the present study, a local Radial Basis Function-based Differential Quadrature [...]

Nano-structure and Phase Transitions in the Liquid Phase of Metallic and Non-metallic Elements

Vezzoli G.C., Institute for the Basic Sciences, US

The generally accepted version of the structure of the liquid phase is that of a single "homogeneous" phase, with a structure which is more or less homogeneous throughout the pressure-Temperature (p-T) field in which it [...]

Glucose Sensors Based on Glucose Oxidase Immobilized in Polypyrrole-Polyacrylamide Microparticles

Rubio-Retama J., Mecerreyes D., University Complutense, ES

Soluble, polypyrrole has been synthesized by the incorporation of the sulphonate dopant anion which renders the polymer soluble in water. The soluble polypyrrole was incorporated in the aqueous phase of a W/O concentrated emulsion, together [...]

Behavior of Living Human Neural Networks on Microelectrode Array Support

Pizzi R., Gelain F., Fantasia A., Rossetti D., Vescovi A., University of Milan, IT

Researchers of the Department of Information Technologies of the University of Milano and of the Stem Cells Research Institute of the DIBIT-S. Raffaele Milano are experimenting the growth of human neural networks of stem cells [...]

Bio-Impedance Sensing Device (BISD) for Detection of Human CD4+ Cells

Mishra N.N., Retterrer S., Zieziulewicz T.J., Isaacson M., Szarowski D., Mousseau D.E., Lawrence D.A., Turner J.N., New York City Department of Health, US

The aim of this work is to develop a small on-chip bio-impedance sensing device (BISD) to rapidly detect and quantify cells with a specific phenotype in a heterogenous population of cells (e.g., human CD4+ cells [...]

Potentiometric Biosensors Based on Silicon and Porous Silicon

Basu I., Subramanian R.V., Mathew A., Chadha A., Bhattacharya E., Indian Institute of Technology Madras, IN

Detection and estimation of Triglycerides and Urea are clinically important. We report fabrication of potentiometric biosensors based on silicon and porous silicon and estimation of triglycerides and urea based on enzymatic reactions. The sensor is [...]

Micro-Patterning of Ionic Reservoirs within a Double Bilayer Lipid Membrane to Fabricate a 2D Array of Ion-Channel Switch Based Electrochemical Biosensors

Sansiñena J.M., Yee C.K., Sapuri A., Swanson B.I., Redondo A., Parikh A.N., Los Alamos National Laboratory, US

We present a simple approach for the design of ionic reservoir arrays within a double phospholipid bilayer to ultimately develop a 2D array of ion-channel switch based electrochemical biosensors. As a first step, a primary [...]
