Ultra-short pulsed laser for nano-texturation associated to plasma immersion implantation for 3D shallow doping : Application to silicon photovoltaic

Halbwax M., Sarnet T., Delaporte Ph., Sentis M., Etienne H., Torregrosa F., Vervisch V., Martinuzzi S., LP3 UMR CNRS 6182, FR

It has been shown in a recent past (Mazur et al) that a simple way to improve the silicon-based solar cells low efficiency (around 20%) is to irradiate the silicon surface with a series of [...]

Amorphous Diamond as a Thermionic Material

Sung J.C., Sung M., Kan M-C, Hsiao T-J., Chen Y-T, Sung J.C., Sung M., Kinik Company, TW

Amorphous diamond is essentially a chaotic carbon mixture with distorted sp2 and sp3 bonds. As such it possesses both metallic character of conductive graphite and semiconductor character of insulating diamond. Moreover, as each carbon atom [...]

Preparation and Characterization of Nafion/Microporous Titanosilicate Composite Membranes as Ion-Conducting Materials

Ryu S.-Y., Jeon J-D, Kwak S-Y, Seoul National Univesity, KR

Solar-Blind Dual-Band UV/IR Photodetectors Integrated on a Single Chip

Starikov D., Boney C., Pillai R., Bensaoula A., Integrated Micro Sensors Inc., US

Currently used flame detectors that are composed of discrete UV and IR solid-state components are bulky, sustain temperatures only below 125°C, and are not capable of detecting a multi-band optical signal with high spatial resolution. [...]

Novel FD SOI Devices Structure for Low Standby Power Applications

Ma M-W, Chao T-S., Kao K-S, Huang J-S, Lei T-F, National Chiao Tung University, TW

In this paper, fully depleted (FD) SOI devices with S/D extension shift and high-k offset spacer were investigated in detail. The results show that the S/D extension shift can decrease Ioff significantly to reduce standby [...]

Growth and Some Enzymatic Responses of E. coli to Photocatalytic TiO2

Erdem A., Metzler D., Chou H.W., Lin H-Y, Huang C.P., University of Delaware, US

The effects of photocatalytic nano-TiO2 on the survival or die-off of E. coli (e.g. TK2) were investigated under ambient conditions. Experimentally, a 28-h E. coli culture was exposed to photocatalytic nano-TiO2 at various concentrations, e.g., [...]

Sorption of Ethylbenzene, Toluene and Xylene onto Crumb Rubber from Aqueous Solutions

Alamo-Nole L.A., Roman F., Perales-Perez O., University Of Puerto Rico at Mayaguez, PR

Crumb rubber is composed of a complex mixture of elastomers (polyisoprene, polybutadiene and styrene-butadiene) and carbon black, as reinforcing agent, among other compounds. The contents of carbon black and the presence of the elastomeric matrix [...]

Serpentine Fluidic Structures for Particle Separation

Kole A.S., Lean M.H., Seo J., Palo Alto Research Center Inc, US

The above abstract is based on a novel technique for particle separation from liquid based solely on fluidic forces on the particles. No external force or filters are used for separation. The idea is scalable [...]

Development of a Mobile Asbestos Decontamination Process

Gerdes T., Rosin A., Willert-Porada M., University of Bayreuth, DE

Within the European project “New Safe and Cost Effective Techniques Against Asbestos Risks” different methods for decontamination of asbestos in asbestos containing wastes, abbreviated as ACW from building industry were investigated. A mobile asbestos decontamination [...]
