Preparation of Photocatalytic Silicon Core-shell Nanoparticles Covered by ZnS Shell in Solid-Gas Reaction

Dvorsky R., Praus P., Svoboda L., Matýsek D., Dropa T., Trojková J., Šollová K., VŠB-Technical University of Ostrava, CZ

For easy handling in some practical processes, active nanoparticles are usually deposited on surfaces of larger carrier particles. In our previous work, the particles of montmorillonite MMT with a mean size of 300 nm served [...]

Nano-Silicon and Non-Oxide Ceramics Synthesis via Gas-phase Sodium Reduction Aerosol Reactor

Schimmoeller B., Massey K., Kodas T., Smith G., Kutsovsky Y., Cabot Corporation, US

The largest volumes of nano-particles in consumer products include carbon black for reinforcement applications (e.g. tires), silicon dioxide (SiO2) as rheology agent (e.g. silicones) and titanium dioxide (TiO2) in pigments and photocatalysts. All of those [...]

Development of a high sensitivity fluorescence immunoassay for Amyloid Beta 42 by a silicon microarray platform

Cretich M., Gagni P., Chiari M., Consiglio Nazionale delle Ricerche, IT

Alzheimer’s disease (AD) affects millions of people around the world with rising incidence as population age. Here we present the use of a label/label free silicon/silicon oxide (Si/SiO2) based microarray platform to develop a highly [...]

Impact of Ink Synthesis on Processing and Properties of Inkjet-Printed Silicon Thin Films

Drahi E., Gupta A., Blayac S., Lombez L., Jubault M., Benaben P., Ecole Nationale Supérieure des Mines de Saint Etienne, FR

Inkjet printing has a high potential for cost reduction in solar cell and thermoelectric industry. This study demonstrates that silicon thin films can be produced by inkjet-printing of a silicon ink followed by consequent drying [...]

Characterization of Solar Grade Silicon Contaminants

Mount G.R., Wang L., Putyera K., Lepage M., Evans Analytical Group, US

The term ‘Solar Grade Silicon (SoG)’ has been used for many years but until recently, there were no specifications as to what this actually meant. Without specifications, suppliers of silicon have been using ‘number of [...]

Novel Immune Biosensors Based on the Structured Nano-Porous Silicon for Control of Mycotoxins in Environmental Objects

Starodub N.F., Slishek N.F., Pylypenko I.V., Pylypenko L.N., Pylypenko I.V., Pylypenko L.N., National University of Life and Environmental Sciences of Ukraine, UA

To meet all the requirements of practice in respect of high sensitivity of analysis of mycotoxins as well as simplicity, cheapness and rapidity of its currying out we propose to use of structured nano-porous silicon [...]

Drift Velocity Calculation in Si Using an Analytical Model for the Phonon Dispersion

Gada M., Vasileska D., Raleva K., Goodnick S.M., Arizona State University, US

It is well known that crystalline silicon is the material of choice for fabrication of integrated circuits because silicon wafers are cheap and silicon dioxide is abundant in nature. Properties of the crystalline silicon have [...]

A new method for vertical growth of silicon nanowire in the vapor-liquid-solid (VLS) process

Kim Y.J., Suh D., Lee M.L., Ryu H., Electronics and Telecommunications Research Institute (ETRI), KR

We present a new facile method for vertical growth of the silicon nanowire (Si NW) that obviates the need for SiCl4 in vapor-liquid-solid (VLS) process. The VLS process that involves SiCl4 has two major disadvantages; [...]

Analysis of GaN Grown on Vertically Standing Fractal-Like Si Nanostructures

Wee Q.X., Soh C.B., Zang K.Y., Chua S.J., Thompson C.V., National University of Singapore (NUS), SG

We have investigated the microstructure and optical properties of GaN grown on vertically standing Si nanostructures by MOCVD. The Si nanostructures array is formed by a simple metal-assisted etching of Si(111) substrates, where both metal [...]
