Synthesis and characterization of nanoreactors within polymeric nanotemplates

Groves M., Jugroot M., Malardier-Jugroot C., McTaggart M., Royal Military College of Canada, CA

The paper will present a novel method for the synthesis of metal nanoclusters with diameters < 3nm within an amphiphilic nanotube template without the use of a reducing agent. This environmentally friendly synthesis occurs at [...]

Preparation of Photocatalytic Silicon Core-shell Nanoparticles Covered by ZnS Shell in Solid-Gas Reaction

Dropa T., Dvorsky R., Matýsek D., Praus P., Šollová K., Svoboda L., Trojková J., VŠB-Technical University of Ostrava, CZ

For easy handling in some practical processes, active nanoparticles are usually deposited on surfaces of larger carrier particles. In our previous work, the particles of montmorillonite MMT with a mean size of 300 nm served [...]

Comparisons of electrochemical sensors for heavy metals detection based on filter paper and transparency film substrate

Cate D.M., Chailapakul O., Henry C.S., Rodthongkum N., Ruecha N., Chulalongkorn Uiversity, TH

Electrochemical sensors based on filter paper and transparency film substrates have been prepared using screen-printing method for the detection of the heavy metals Pb2+, Cd2+, and Zn2+. The electrochemical characteristics of these electrodes were analyzed [...]

Polymer nanocomposites reinforced with nanoparticles extracted from renewable resources

Dufresne A., Grenoble institute of technology, FR

There has been an explosion of interest in the use of biomass as a source of renewable energy and materials. One focus of this activity has followed from the recognition that, by suitable chemical and [...]

Soluble Graphene Hybrid Composite (GHC) by Physical Functionalization

Dinh D., Dinh H., Le G.V., Le T.M., Nguyen K.C., Nguyen T.T., DHK GRAPHENOLOGIES LLC, US

Generally speaking, the CVD process of CH4 gas on copper substrate renders a rigid and conductive film from extended graphene molecule which is hard to be produced in large scale. The graphene oxide (GO) is [...]

A New Biocomposite Electrode Sensor for the Detection of Oxidative Reactions

Assan D., Gao X., Lai J.C.K., Leung S.W., Idaho State University, US

Hemoglobin has a very strong affinity with oxygen and thus is a good catalyst to carry oxygen for many oxidation reactions. Many researchers have explored this property of hemoglobin to develop sensors for the detection [...]

Magneto-optic Response of Iron Oxide Nanoparticles under Pulsed and AC Fields

Foulkes T., Syed M., Rose-Hulman Institute of Technology, US

Reliable methods for studying the magnetization dynamics of metal ferrite nanoparticles (NP) are needed, as these particles are attractive candidates for biomedical applications such as in targeted drug delivery, imaging, and magnetic hyperthermia. We investigate [...]

A New Separation Metric for the Optimization of AF4 Separations of Polydispersed Nanomaterials

Filliben J.J., Galyean A.A., Holbrook R.D., Vreeland W.N., Weinberg H.S., University of North Carolina at Chapel Hill, US

The development of standardized and optimized methods to monitor the behavior of engineered nanomaterials (ENMs) in complex environments is considered a critical component in ENM risk assessment. Robust, rigorously optimized methods are currently lacking, in [...]

Fast and Facile Synthesis of Stable and Biocompatible Silver nanoparticles Stabilized by Polyethylene Glycol

Jain S., Pillai S., Singh S., Alabama State University, US

Silver nanoparticles show enhanced properties, when supported onto a substrate and incorporated into organic or inorganic matrix. Their remarkable properties are shape and size dependent. Ethylene glycol and its polymers are environment friendly or environmentally [...]

Differentiating electro-catalytic reaction of hydride with respect to a non-Pt catalyst morphology based on first-principles: extended surfaces versus nanoparticles

Kasai H., Lacdao Arevalo R., Sison Escaño M.C., University of Fukui, JP

One of the attractive hydride compounds is the borohydride which exhibits high hydrogen content in NaBH4 form (~10.6 wt%). Thus, significant number of experimental research have been devoted to investigate its applicability as a hydrogen [...]
