A New Sonochemical Synthesis Route for Silicon Nanoparticle Inks for Energy and Nanomedical Applications

Cádiz Bedini A.P., Chen C., Klingebiel B., Notten P.H.L., Rau U., Forschungszentrum Jülich, DE

Silicon nanoparticles (Si-NPs) have become increasingly relevant in several important fields ranging from solar cells, next-generation quantum dot LEDs, lithium-ion batteries, and because silicon is biodegradable, their use as drug carriers or fluorescent markers has [...]

Direct imprinting of liquid silicon

Masuda T., Shimoda T., Japan Advanced Institute of Science and Technology, JP

Silicon is one of the most important materials for electronics. The most widespread process for microfabrication technology of silicon is photolithography including etching process. However, huge capital outlay and large-scale equipment has been recognized as [...]

Learning MEMS Design, Simulation and Fabrication Through 3-D Printing

Dahle R., Rasel R., SUNY New Paltz, US

This paper presents a cost-effective learning tool for modeling and simulating the microfabrication process and design aspects of MEMS devices using three-dimensional (3-D) printing. This approach was developed to provide engineering educators a more affordable [...]

Characteristic Fluctuation of Gate-All-Around Silicon Nanowire MOSFETs Induced by Random Discrete Dopants from Source/Drain Extensions

Sung W-L., National Chiao Tung University, TW

In this study, we explore characteristic fluctuation of gate-all-around silicon nanowire MOSFETs induced by random discrete dopants (RDDs) resulting from source/drain extensions. Compared with the results of source extension, asymmetric variations of characteristics induced by [...]

Cavitation Disintegration of Microparticles and Nanoparticles in Dense Liquid Dispersions

Dvorsky R., Svoboda L., Trojková J., Bednář J., Mančík P., Kostura B., Vysoká škola báňská – Technická univerzita Ostrava, CZ

With the current rapid development of nanotechnology, top-down preparation of nanoparticles by various disintegration techniques became an important industrial sector. In addition to the presently common high speed bead mills working with particles in liquid [...]

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 [...]

Composite Li-Ion Anodes from Recycled Silicon

Xu W., Electrochemical Materials, US

Silicon byproducts from sources such as kerf are difficult to use directly as lithium-ion batteries since key parameters such as silicon particle size, surface oxides, and impurities, do not fulfill the requirements for silicon anode [...]

Silicon byproducts from sources such as kerf are difficult to use directly as lithium-ion batteries since key parameters such as silicon particle size, surface oxides, and impurities, do not fulfill the requirements for silicon anode [...]

On-line production of polyelectrolyte coating on monodisperse alginate beads in an integrated microfluidic cartridge

Laffite G., Forvi E., Hadji C., Authesserre C., Alessio M., Costa G., Boizot F., Rivera F., CEA-LETI, FR

Continuous flow microfluidic devices have appeared to be a promising technology to automatise Polyelectrolytes multilayers (PEMs) coating on microbeads with repeatable and reliable results. However, no microfluidic devices have demonstrated PEMs coating on hydrogel beads [...]

CMOS-Compatible Thermally Actuated MEMS Viscosity Sensor with Aluminum on Silicon Membrane

Puchades I., Fuller L.F., Lyshevski S.E., Rochester Institute of Technology, US

This paper presents viscosity measurements performed on standard commercially-calibrated oils as well as to motor oils measured on a commercial cone-and-plate viscometer. Figure 2 shows the response of the sensor, in the frequency domain, when [...]
