Synthesis and Characterization of Nanocomposites Using the Nanoscale Laser Soldering in Liquid Technique

Phuoc T.X., Mcintyre D., Song X., Chyu M.K., National Energy Technology Lab, US

It has been known that catalytic and sensing properties of semiconductor and metal nanoparticles (NPs) can be greatly enhanced if they are made in the form of nanocomposites. For that reason, in this work, we [...]

Copper Oxide–Cobalt Oxide Nanoscale Heterostructures for Photocatalysis

Shi W., Chopra N., The University of Alabama, US

The research work discussed here will be focused on development of multifunctional nanoscale heterostructured photocatalysts comprised of oxides of copper and cobalt. Two fabrication approaches are described: a) solution and b) dry processing route. The [...]

Synthesis and characterization of magnetic manganese ferrites using a simple combustion method and its application in removal of organics

Desai I., Mills M., Nadagouda M., Elovitz M., Boulanger B., U.S. Environmental Protection Agency, US

Ferrospinels have been shown to have promising oxidative and catalytic properties. Our research focuses on novel magnetic manganese ferrite catalysts which have been developed and thoroughly characterized. Their potential application as oxidative catalysts/sorption in removal [...]

Nanobiotechlogy: Applications in Food Science and Engineering

Sadeghi R., Ansari S., Uzun S., Bozkurt F., Gezer P.G., Karimi M., Kokini J., University of Illinois at Urbana-Champaign, US

Quantum (QD) dots were conjugated to anti-gliadin antibody and used as a fluorescent probes to track gliadin protein in dough and baked bread samples. CLSM images showed significant changes in the distribution of gliadin within [...]

Practical synthesis of nanomaterials and nanostructures

Rae A., Matteson J., Dansoh V., NanoMaterials Innovation Center, US

Nanoparticle and nanostructured coating synthesis is commonly hampered by complex processes or the need to use precursors which may not yet be registered under TSCA or REACH. There are, however, simple and practical processes using [...]

Encapsulation of pesticide nanoparticles using polymerized carbon nanotubes and application of synthesized nanocomposite for Alternaria alternata fungi

Sarlak N., Taherifar A., Nejad M.A.F., Zabeti S.M., Salehi F., University of North Carolina at Chapel Hill, US

Polymerization of citric acid onto the surface of oxidized multi wall carbon nanotubes was led to MWCNT-graft-poly (citric acid) (MWCNT-g-PCA) hybrid materials. Trapping of pesticides such as Benomyl, Trichlorfon and Pymetrozine (chess) in aqueous solution [...]

Visible Upconversion in Rare-earth Ion-doped NaYF4 Crystals and Nanocoloids

Patel D.N., Jumper M., Wright III D.M., Sarkisov S., Oakwood University, US

Nano-colloids and nano-crystals doped with rare-earth elements have recently attracted a lot of attention in the scientific community. This attention is due to unique physical, chemical and optical properties attributed to nanometer size of the [...]

Synthesis of Magnetically Sensitive Nanomaterials with Tunable Properties

Ieta A., Patus J., Apenowic J., Marius C., State University of New York at Oswego, US

New magnetic nanomaterials with tunable properties were produced using three procedures. (1) Mixtures of polyvinyl alcohol (PVA) solutions and ferric oxide [3] based ferrofluid were prepared and also electrospun with the purpose of synthesizing magnetic [...]

Highly Spherical Gold Nanoparticles by Laser Pulse Heating

Cavicchi R.E., Meier D.C., Presser C., Guha S., National Institute of Standards and Technology, US

Methods continue to be developed for improving the size and shape uniformity of Au nanoparticles (NP), however, fabricated NPs tend to be faceted and not highly spherical. We present results that show that the faceted [...]

Synthesis of Micrometric Single Crystalline Magnetite with Superparamagnetic Properties for Biomedical Applications

Chirita M., Kiss M.L., Ieta A., Grozescu I., State University of New York at Oswego, US

There are no reports on the synthesis of single crystalline micrometric magnetite with superparamagnetic behavior. The literature mainly refers to micrometric particles obtained by nanoparticle agglomeration. The major disadvantage of magnetic microparticles composed of clusters [...]
