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); [...]

Extremely Flexible and Stretchable Carbon Nanotube Composites for Conformal Electronic Devices

Landorf C.W., Alford J., Garrison J., Gibbons S., Shih W-S, Leever B.J., Berrigan J.D., Brewer Science, Inc, US

Electronic devices are increasingly being used in products that are not expected to be rigid and flat. Many strategies have been implemented to create electronics that can work under stress and strain that would fracture [...]

Strain Tunable Resin and Coating Technology for Next Generation Composites

Lewit S.M., Structural Composites, Inc, US

Leveraging SBIR Technology for Advanced Combatant Craft has created an innovative new resin and coating technology Our patent pending Co-Cure technology allows for shop floor alteration of coating and resin properties. The invention relates to [...]

Ethylene Vinyl Acetate – Cloisite Nanocomposite Membranes and their Gas Separation Behavior

Ramadan A.R., Esawi A.M.K., Abdel-Hafiz A., Charmette C., Ayral A., The American University in Cairo, EG

The current work aims at understanding the correlation between EVA-montmorillonite clay nanocomposite membrane morphology and gas permeation properties. 5wt% of Cloisite-20A and 30B organoclays were added to EVA having 18wt% vinyl acetate. Nanocomposite membranes were [...]

Thermoelectric properties of nanocomposite Bi2Te3 layers prepared by PLD

Zeipl R., Jelinek M., Vlčekb M., Kocourek T., Vanišc J., Institute of Physics ASCR, CZ

We present some thermoelectric properties of Bi2Te3 nano-layers of different thickness prepared by Pulsed Laser Deposition such as the thermal conductivity, in-plain electrical conductivity and the Seebeck coefficient. Layers are prepared under various deposition conditions. [...]

Inducing Polymer Interphase Formation in the Composite at Low Nano-Carbon Loading

Song K., Minus M.L., Northeastern University, US

The nano-carbons used in this work are layered carbon nano-chips that exhibit platelet morphology and are able to slide with respect to each other. Both filled and unfilled poly(vinyl alcohol) (PVA) fibers were studied to [...]

Field-Limited Digestive Ripening for Self-Organization of Thiol-Capped Gold Nanoparticles

Lin M.L., Yang F., Peng J.S., Hsu C-M, Lee S., National United University, TW

It is known that the nearly monodisperse gold particles of nanosizes could be prepared by using digestive ripening. Based on the assumption of charged particles, the model for expressing the digestive ripening has been proposed. [...]

Gaseous Nanobubbles – Surface Nanopatterning Elements

Janda P., Tarabkova H., J. Heyrovsky Institute of Physical Chemistry ASCR, CZ

Gaseous nanobubbles adhering to solid surfaces immersed in de-ionized water were found to exhibit interfacial forces capable of nanopatterning hydrophobic surfaces at mild conditions. Random and net-like periodic nanopattern imprinted in polymeric film represent images [...]

Numerical Analysis of Laser Induced Photothermal Effects using Colloidal Plasmonic Nanostructures

Karampelas I.H., Kim Y.H., Furlani E.P., University at Buffalo (SUNY), US

Colloidal plasmonic nanostructures are finding increasing use in a variety of applications that range from nanoparticle synthesis to bioimaging to medical therapy. In many such applications, a pulsed laser is used to heat plasmonic nanostructures [...]

A structural analysis of olive oil organogelation

Filippelli L., Gentile L., Lupi F.R., Rossi C.O., Baldino N., Ranieri G.A., Gabriele D., University of Calabria, IT

Organogels based on liquid vegetable oils are possible replacers of saturated or hydrogenated fats in the food industry. There is still a lack of information about the link between macroscopic parameters and material microstructure. By [...]
