Gas Sensor with SAW Structures

Laposa A., Husak M., Kroutil J., Czech Technical University in Prague, Faculty of Electrical Engineering, CZ

The objective of this paper is presents the modeling and simulation of SAW (Surface Acoustic Wave) gas sensors based on one-port and two-port interdigitated metal structures. These sensors can be used for identifying environmental contaminants [...]

The Fabrication and Multi-Physics Simulation of a Novel Low Power Electrothermal Bimorph Actuator

Lou W-Z, Guo M-R, Lv Y-J, Beijing Institute of Technology, CN

A novel electrothermal bimorph actuator was designed for low-power (below 300mW), quick-response (below 10ms) switching application. The research work was supported by the Funds for National Key Laboratory (9140C3605101006). Three aspects about the electrothermal bimorph [...]

Analog/RF Performance Analysis of Coaxial Carbon Nanotube MOSFET from non-Equilibrium Green’s Function Simulation

Che Y., Chen Q., Liang H., Chen Q., Wang C., He H., Cao Y., PKU-HKUST Shenzhen-Hongkong Institution, CN

the analog/RF performance of Coaxial Carbon Nanotube Field Effect Transistor (CNTFET) including the trans-conductance efficiency gm/Id, cutoff frequency ft, and maximum oscillation frequency fmax are analyzed in details in this paper based on the non-equilibrium [...]

High-Fidelity Modeling of Single Molecule Quantum Electronic Devices

Lyshevski S.E., Rochester Institute of Technology, US

Departing from two-terminal molecular electronic devices, this paper examines multi-terminal MEdevices. These devices are envisioned to be utilized in emerging molecular gates (Mgates) and neuronal hypercells for expected molecular integrated circuits. High-fidelity modeling and heterogeneous [...]

CFD-Assisted Design and Optimization of a Pharmacokinetic Microfluidic System

Moeini Sedeh M., Khodadadi J.M., Hong J.W., Cramer K.A., Hamon M., Auburn University, US

In this research, a microfluidic system was designed and optimized to carry out in vitro pharmacokinetic studies of drug candidates in the liver. Computational fluid dynamics (CFD) was called on to assist in the system [...]

Performance Study of Nitride-Based Gunn Diodes

Aloise G., Vitanov S., Palankovski V., Advanced Material and Device Analysis Group, AT

In this work, we assess the performance of InN Gunn diodes, as a superior alternative to GaN. We perform two-dimensional mixed-mode device/circuit simulation accounting for self-heating effects. We verify available theoretical results for GaN-based Gunn [...]

Analytical investigation of nanofluids dispersion stability

Farzaneh H., Behzadmehr A., Samimi A., University of Sistan and Baluchestan, IR

Experimental and numerical investigations on nanofluids flows at different geometrical configurations and different thermo-fluid conditions show a significant enhancement on the convective heat transfer while the pumping power cost remains reasonable. However, many problems such [...]
