Novel pretreatment strategies of algal biomass for the production of bioethanol

, Qatar University, QA

Bioethanol is a liquid biofuel that is sustainable and environmentally friendly [19]. However, the production and commercialization of bioethanol is primarily focused on first-generation food crops such as sugarcane, maize and beet, which can lead [...]

A Piezoresistive MEMS Memory Device Using a Buckled Beam

Yang J.A., Shuvra P.D., Lin J-T., Walsh K., McNamara S., Alphenaar B., University of Texas at Austin, US

Microelectronics and microelectromechanical systems (MEMS) have given rise to a large class of new de- vices, from ultra-miniature sensors for cell phones and automobiles to complex memory devices for computers. Recent research in memory devices [...]

Optimized internal geometries for lightweighting and multifunctionality in additive manufacturing – an ideal processing target

Berger J., Nama Development LLC, US

One of the great opportunities in additive manufacturing is the ability to manufacture complex optimized internal geometries such as lattices and honeycombs for space filling applications. Some obvious applications including sandwich panels for lightweighting and [...]

Strategies for production of naturally-derived calcium phosphates particles for solid free-form fabrication

Miculescu F., Miculescu M., Maidaniuc A., Voicu S.I., Miculescu F., Miculescu M., Batalu D., University Politehnica from Bucharest, RO

In this abstract we propose the strategies optimization for obtaining ceramic materials derived from natural sources for solid free-form fabrication, used for bone substitution. The selected method, thermal processing, is simple (due to the similarities [...]

Optimization of a Poly-SiGe MEMS Xylophone Bar Magnetometer based on its equivalent circuit

Rochus V., Farghaly M., Rottenberg X., Tilmans H.A.C., IMEC, BE

This paper presents the optimization of a poly-SiGe-based MEMS Xylophone Bar Magnetometer (XBM) using a novel characterization method based on the measurement of the forward/backward transmission gains S21/S12 of the XBM treated as a two-port [...]

Opto-Electrical Study of Spectrally Enhanced Thin Film Solar Devices

Hajimirza S., Howell J.R., The University of Texas at Austin, US

We report optical and electrical study of a light trapping for efficiency enhancement in thin film amorphous silicon. Solar absorption can be improved inside thin films via surface texturing, plasmonic excitations and thin anti-reflecting coating. [...]

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 [...]

Optimization study of Supercapacitor electrode material composition and thickness for enhanced performance of the Supercapacitor

Ranade A.P., Jung D.Y., Sammakia B.G., Eilertsen T., Davis T., Binghamton University, US

A prototype electrode was constructed to verify the optimization of composition of materials for the supercapacitors. Surface area analysis and SEM images were used initially to select the most appropriate active carbon from a group [...]
