Influence of Nanoclay’s Incorporation On Mechanical and Thermogravimetric Properties of ER/MWCNT Composites

Stimoniaris A.Z., Zois H., Kanapitsas A., Delides C.G., Technological Educational Institute Of Lamia, GR

In this work polymer nanocomposite systems based on epoxy resin (ER), reinforced with amine-modified multi-walled carbon nanotubes (MWCNTs) and/or nanoclays were studied. Thermogravimetric/Differential Thermal Analysis (TGA/DTA) and Dynamic Mechanical Analysis (DMA) techniques were carried out. [...]

Optimization of the device design technologies for optimum analog/RF performance of Nanoscale DG MOSFETs

Sharma R.K., Bucher M., Technical University of Crete, GR

Analog/RF performance of new device architecture: graded channel dual material double gate (GCDMDG) is investigated using ATLAS device simulator. A close comparison with double gate (DG), graded channel double gate (GCDG) and dual material double [...]

Evaluation of Hydrogen Storage in Clathrate Hydrates: Review of Recent Advances

Tsimpanogiannis I.N., Stubos A.K., National Center for Scientific Research “Demokritos”, GR

The adoption of “Hydrogen Route” is considered as a promising alternative to meet our long-term energy needs. In this approach energy is stored/transferred and used in the form of hydrogen. Hydrogen is a versatile molecule [...]

Bias Dependence of Low Frequency Noise in 90nm CMOS

Mavredakis N., Antonopoulos A., Bucher M., Technical University of Crete, GR

The bias dependence of low frequency noise (LFN) is investigated with measurements in 90nm CMOS. A recent charge-based LFN model combining carrier and mobility fluctuation components is compared to data from multi-finger devices with a [...]

Experimental Study of Drying/Evaporation in an Effective 2D Porous Medium

Yiotis A.G., Tsimpanogiannis I.N., Stubos A.K., National Center for Scientific Research “Demokritos”, GR

Liquid-to-gas phase change, where the mass transfer that drives the process occurs in the gas phase, and the subsequent growth of the produced gas phase within a porous medium, is involved in a wide variety [...]
