Novel Nanoparticle Contrast Agents for Magnetic Resonance Imaging

Van Keuren E., Stoll S., Dahanayake V., Lyons T., Glaser P., Albanese C., Rodriguez O., Fricke S., Georgetown University, US

Magnetic resonance imaging (MRI) is an important diagnostic tool in both clinical and research environments. In order to improve sensitivity, contrast agents (CAs) are often administered prior to or during imaging sessions. We have been [...]

New Nano Solid Based on Carbon Nanomaterials-Nanoparticle through Aqueous Solutions

Hong H., Younes H., Grablander T., Bailey C., Novum Nano, US

A better understanding of the bonding and aggregation processes occurring between carbon nanomaterials and metal oxide particles in aqueous solutions is important in developing novel nanosolids for applications in sensor development, highly conductive paint nanotube [...]

Flame-based Aerosol Synthesis of Metal Nanoparticles and Supported-Metal Nanostructures

Liu S., Swihart M.T., University at Buffalo (SUNY), US

Commercialization of inorganic nanomaterials is often limited by scale-up. Our group developed a unique flame- based aerosol process for scalable, continuous, and low-cost production of various nanomaterials, the High Temperature Reducing Jet (HTRJ) Reactor. Over [...]

Remote control of mechano-sensory function of primary cilia by Fe2O3 nanoparticles in ciliopathic animal models

Pala R., Nauli S.M., Chapman University and University of California Irvine, US

In the present studies, we designed a cilia-targeted delivery system to deliver fenoldopam (FD) specifically to the primary cilia. Hence, we devised the iron oxide nanoparticle (Fe2O3-NP)-based technology for ciliotherapy. Dynamic light scattering measurements showed [...]

A Novel Colorimetric H2S Measurement for Environmental and Oil and Gas Applications

Skates V.W.L., van Hal R.E.G., Schlumberger-Doll Research, US

This paper provides a novel colorimetric method to measure hydrogen sulfide in water, air, natural gas and oil. A bismuth ion based reagent reacts with sulfide to form bismuth sulfide nanoparticles, causing the solution to [...]

Comprehensive Analysis of High Performing Electrochemical Biosensors and Their Applications: II, System Update

Leung S.W., Lai J.C.K., Idaho State University, US

We have mounted 5 different biocatalysts on a sensor platform to examine the performance of this electrochemical sensing system for the detection of different biomolecules/metabolites and environmental important molecules, with such we also compared how [...]

The Use of Focused Aerosol Deposition in the Collection and Analysis of Nanoparticles from Ultrapure Water Systems Used in Semiconductor and Pharmaceutical Industry

Van Schooneveld G., Keady P., Oberreit D., CT Associates, Inc, US

The reduction of particles in ultrapure water (UPW) systems is driven primarily by the semiconductor industry. Particles that can produce defects in chip manufacturing and potentially reduce yield, are now identified to be 10 nm [...]

Novel Post Treatment of Nano-Particle Reinforced Metallic Coatings

Tay S.L., Goode C., Cirrus Materials Science, NZ

Electrochemical co-deposition of metallic coatings with a second phase material have been widely applied in industry to improve the properties of coatings. A variety of hard oxide, carbide, nitride, and ceramic nanoparticles have been successfully [...]

A platform for extremely sensitive gas sensing: 2D materials on silicon carbide

Eriksson J., Rodner M., Yakimova R., Spetz A.L., Linkoping University, SE

2D materials offer a unique platform for sensing with extremely high sensitivity, since even minimal chemical interaction causes noticeable changes in the electronic state. An area where extreme sensitivity is particularly interesting is in the [...]

Partially Poisoned Pd Nanoparticles for Selective Hydrogenation and/or Isomerization of Olefins

Shon Y-S, California State University Long Beach, US

Selective hydrogenation and/or isomerization of olefins are important processes in both chemical and pharmaceutical industries. Our group previously reported that the thiosulfate protocol using sodium S-alkylthiosulfates instead of alkanethiols could generate catalytically active Pd nanoparticles [...]
