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, [...]

Vertically Aligned Graphene sheets Based Coatings as Nano-micro-structured Electrodes for Enhanced Performance of Supercapacitors

Jang G.G., Keum J.K., Song B., Li L., Hensley D.K., Jiang Y., Hunt A., Moon K-S, Wong C.P., Hu M.Z., Hunt A., Oak Ridge National Laboratory, US

This work develops a molecular engineering approach to control the interspacing of graphene sheets and then an external field approach to induce the re-orientation of the graphene sheets during the deposition process to form a [...]

Graphene Oxide/Vinyl Ester Resin Nanocomposite: Effect of Graphene Oxide, Thermal Stability, and Modeling of the Curing Kinetics”

Arabli V., Aghili A., National Iranian Oil Company, IR

Graphene oxide (GO) was synthesized and nanocomposites were prepared using different contents of the GO and vinyl ester resin (VE). The onisothermal differential scanning calorimetry (DSC) was used to study the cure kinetics of VE [...]

Mechanical and Dielectric Properties of Polyhedral Oligomeric Silsesquioxanes Modified Graphene Oxide/Polyimide Nanocomposites

Ma C.-C.M., Liao W-H, Hsiao S-T, Wang Y-S, Li S-M, Liao W-H, Lin S-C, Lin S-C, National Tsing Hua University, TW

An effective method is proposed to prepare octa(aminophenyl) silsesquioxane (OAPS) functionalized graphene oxide (GO) reinforced polyimide (PI) composites with a low dielectric constant and ultra-high mechanical properties. The amine-functionalized surface of OAPS-GO is a versatile [...]
