Natural polyphenols as pro-ecological antioxidants and pigments for polymer composites

Masek A., Zaborski M., Lodz University of Technology, PL

In our studies, we propose the use of natural, pro-ecological substances such as polyphenols to protect elastomers against ageing. This natural compounds were incorporated into ethylene-norbornene (COC-material is commercially available under the name of TOPAS); [...]

CO2 reforming of CH4 by the combination of dielectric barrier discharge plasmas and zeolite catalysts

Nguyen H.H., Kim K.S., Kangwon National University, KR

Dry reforming of two green-house gases (CH4 and CO2) to convert to syngas (mixture of CO and H2) has gained deep research interests lately. Several technologies were proposed to convert the CO2 and CH4, such [...]

Development of a Platinum Nanoparticle based Microcombustor Power Device

Bakrania S., Rowan University, US

Microcombustors coupled with thermoelectric devices have the potential to provide a prolonged power source for portable devices as opposed to conventional batteries due to significantly higher energy densities. Recharging then can be easily achieved by [...]

Synthesis and characterization of nanoreactors within polymeric nanotemplates

McTaggart M., Groves M., Malardier-Jugroot C., Jugroot M., Malardier-Jugroot C., 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

Dvorsky R., Praus P., Svoboda L., Matýsek D., Dropa T., Trojková J., Šollová K., 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

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

Le G.V., Le T.M., Dinh D., Dinh H., Dinh D., Dinh H., Nguyen K.C., Nguyen T.T., Nguyen K.C., Nguyen T.T., Le G.V., Le T.M., 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

Syed M., Foulkes T., 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 [...]
