Encapsulation and controlled thermal release of vegetable oils from organic nanoparticles for functional coating applications

Samyn P., Stanssens D., University of Freiburg - Freiburg Institute for Advanced Studies, DE

Nanoparticle pigments of poly(styrene-maleimide) or SMI have been synthesized containing different vegetable oils that favourably can be applied as a barrier resistant coating against water and oil penetration onto paper substrates and regulate its surface [...]

Analytical system capable of rapidly quantifying food-borne pathogen for food safety and public health

Khang J., Kim D., Chung K.W., Lee J-H., Luminescent MD, LLC, US

Cost-effective and easy-to-use biosensor was developed for the rapid quantification and monitoring of Escherichia (E.) Coli O157:H7 in sample using E. Coli O157:H7 aptamer, graphene oxide (GO)/iron nanocomposites, and guanine chemiluminescence detection. E. Coli O157:H7 [...]

Peering into polymer dynamics in carbon nanocomposites

Ashkar R., Bertrand C., Abdulbaki M., Tyagi M., Faranone A., Butler P., Krishnamoorti R., National Institute of Standard and Technology, US

Carbon nanocomposites have received significant attention owing to the unique properties of carbon nanoparticles. However, the promised enhancement in carbon nanocomposites has not been fulfilled yet. Lately, there has been a growing consensus that material [...]

In Vitro Assessment of a Novel Cancer Therapy Combining Drug Loaded Magnetic Nanoparticles and Magnetic Hyperthermia

Ni Q., Texas A&M International University, US

We propose to develop a novel combination therapy for prostate/breast treatment by combining two treatment modalities (hyperthermia therapy and chemotherapy) into one using MCaP nanoparticles (NP) system. Our proposed MCaP NPs possess unique properties, including: [...]

Structure and Mechanical Properties of Cr(Al)N/Al2O3 Nanocomposite Hard Coatings Fabricated by Differential Pumping Cosputtering

Kawasaaki M., Onishi I., Matsuda K., Nose M., Shiojiri M., JEOL USA Inc., US

Analytical electron microscopy revealed the structure of Cr(Al)N/Al2O3 nanocomposite coatings prepared on the Si substrate rotated at a speed as high as 12 rpm in a differential pumping cosputtering system(DPCS). The main layer that sputter-deposited [...]

Fluorescent-Plasmonic Quantum Dot-Gold based Nanohybrids: Basic Research for Next Generation Materials and Tracking of Biological Events

Merkl J.-P., Schmidtke C., Aldeek F., Safi M., Strelow C., Feld A., Kloust H., Heidari H., Bals S., Lange H., Mattoussi H., Weller H., University of Hamburg, DE

A novel hybrid nanoparticle is presented based on encapsulated fluorescent CdSe/ZnSe/ZnS core/shell/shell quantum dots (QDs) with zwitterionic capped gold nanoparticles (AuNPs). This hybrid is fully characterizes by variouse techniques including optical spectroscopy, (cryo) transmission electron [...]

Conductive Ppy-DS/Fe-MMT Layered Nanocomposites

Enomoto H., Kanda R., Lerner M.M., Osaka Electro-Communication University, JP

Conductive polypyrrole/montmorillonite (Ppy/MMT) nanocomposites were synthesized by the in-situ polymerization of Ppy in the gallery of MMT layers. The constrained environment of the interlayer gallery of clay host is expected to serve as a template [...]

Investigating Environmental Weathering of CNF/CNT/ Thermoplastic Polymer Synthesized using Additive Manufacturing

Sahle-Demessie E., Zhao Amy, Stephen Chady, U.S. Environmental Protection Agency, US

Additive manufacturing (aka, 3D printing) is an emerging technology for making a new class of multifunctional nanocomposites for many niche items such as medical implants, and a wide range of industrial designed components. Additive manufacturing [...]

Nanocomposite optimization using polymer-wrapped carbon nanofibers

Papantonakis M.R., Barbano M.E., Ou W., Gorzkowski E.P., McGill R.A., US Naval Research Laboratory, US

We present results for carbon nanofibers modified by physisorption with a range of polymer modifiers and then dispersed in different polymeric hosts with mechanical advantage and other applications in mind. In contrast to covalent bonded [...]

Polymer Nanocomposites Incorporating Boron Nitride Nanotubes

Jakubinek M.B., Martinez-Rubi Y., Ashrafi B., Guan J., Kim K.S., O’Neill K., Kingston C.T., Simard B., National Research Council Canada, CA

Boron nitride nanotubes (BNNTs) are structurally analogous to carbon nanotubes (CNTs) and possess equally impressive mechanical properties along with a different set of multifunctional properties including higher thermal stability than CNTs, wide band gap, electrical [...]
