Optimization of synthesis conditions to prepare desired shell thickness of superparamagnetic MgFe2O4@SiO2 core-shell nanosphere for biomedical applications

Das H., Debnath N., Arai T., Sakamoto N., Shinozaki K., Suzuki H., Wakiya N., Shizuoka University, JP

We have described here a simple way for the fabrication of superparamagnetic MgFe2O4@SiO2 core-shell spherical nanoparticles with controlled shell thickness. First, core MgFe2O4 dense nano-spheres were directly synthesized by ultrasonic spray pyrolysis (USP) technique from [...]

Controlled Synthesis of Near IR Emitting Metal Chalcogenide Quantum Dots for the Opto-electronic Applications

Hocaoglu I., Eral Dogan L., Dagtepe P., Kuantag Nanotechnologies Development and Production Inc., TR

Studies on the synthesis of Near IR emitting Quantum Dots have increased due to their potential in fiber optic communication systems, in photovoltaic cells, in NIR detectors-cameras, in biological applications including in vitro and in [...]

Characterization of Crosslinked Polymer Nanoparticles by Size-Exclusion Chromatography Coupled to Differential Viscometery

Kalantar T.H., Meunier D.M., Lyons J.W., Kiefer J.J., Niu Q.J., Li Y., Bouck K.J., Tucker C.J., Russo P.S., Cueto R., Dow Chemical Company, US

Conventional size-exclusion chromatography (SEC) and size-exclusion chromatography coupled to differential viscometry (SEC/DV) methodologies have been developed and applied to the dilute suspension characterization of solvent-swollen crosslinked unimolecular polymeric nanoparticles (PNPs) in the 5 ~ 50 [...]

Synergistic response of ionic liquid ([bmim][BF4]) entrapped in BHDC reverse micelles for gold nanoparticles synthesis. Size and morphology control

Blach D., Martinez F., Universidad Industrial de Santander, CO

Nanoparticles (NPs) have been extensively investigated for many application due to their unique properties, particularly gold nanoparticles (AuNPs) stand out because their properties triggered by small changes in their size and morphology. Nowadays, the great [...]

Atmospheric Pressure Spatial ALD onto Powders with Conventional Powder Handling Equipment

Spencer II J.A., Hall R.A., Trujillo-Sullivan K., Groner M.D., ALD NanoSolutions, Inc., US

The manufacturability of ALD coatings on commodity particle substrates requires the development of cost effective ALD processing for industrial scales. We have developed a fully continuous spatial particle ALD system based on conventional powder handling [...]

Design and Simulation on Nanoelectromechanical bi-layer Graphene Nanoribbon Device with Graphene Nanoflake Shuttle

Kwon O-K., Kang J-W, Lee J-H., Semyung University, KR

Nanoelectromechanical (NEM) switches are similar to conventional semiconductor switches in that they can be used as relays, transistors, logic devices and sensors, and they are promising devices for use in mechanical computing, data storage, and [...]

Graphene Oxide and Reduced Graphene Oxide and Their Water Purification Properties

Baruah B., Baruah S., Kohler G., Baruah B., Baruah S., Kennesaw State University, US

In this study, we synthesized graphene oxide (GO) from graphite with slight modification of literature method. We have deposited purified GO on pure sand to generate GO@sand composite. The GO@sand composite was further reduced chemically [...]

Carbon Nanotubes on Graphene – Interfacial and Electrical Properties

Senegor R., Adesida A., Zhou C., Vyas A.A., Wang P., Yang C.Y., Santa Clara University, US

Continuous downward scaling in silicon integrated circuit technology into the sub-20 nm regime has created critical challenges in chip manufacturing, among them, reliability and performance of on-chip interconnects [1]. Current interconnect materials, Cu and W, [...]
