ZnO:Polydiacetylene Films as Chromatic Sensors

Patlolla A., Zunino III J.L., Schmidt D.P., Iqbal Z., Skelton D.R., U.S. Army, US

Films of the conjugated polydiacetylenes (PDAs) can function as chromatic temperature, chemical and stress sensors, and can be prepared by spin-coating from monomer solutions followed by polymerization. The polymer backbone of PDAs is comprised of [...]

Synthesis and Application of nano-size polymer colloids at The Dow Chemical Company

Tucker C.J., The Dow Chemical Company, US

Over the last 50+ years The Dow Chemical Company has sponsored numerous research programs involving the preparation and use of nano-size colloidal systems. The nano-colloids used range from soft (liquid microemulsions) to solid (polymeric) materials [...]

Evaluations of PP-g-GMA and PP-g-HEMA as a Compatibilizer for Polypropylene/Clay Nanocomposites

Kim D-H., Son Y., Kongju National University, KR

In this study, we investigated the performances of a hydroxy ethyl methacrylate grafted PP (PP-g-HEMA) and a glycidyl methacrylate grafted PP (PP-g-GMA) as compatibilizers in PP/clay nanocomposites. The compatibilizers were prepared by melt grafting with [...]

The magnetic properties optimization in diluted magnetic oxide semiconductor nanoparticles obtained by a modified co-precipitation approach in intrazeolitic networks

Bosinceanu R., Iacomi F., Al.I.Cuza, RO

Ferromagnetism in diluted magnetic semiconductors (DMS) has been a subject of great scientific and technological interest for the past few years due to its implications for spintronics, advanced magneto-optics and sensors applications. Our research involves [...]

Nanohybrid silica/polymer subcritical aerogels

Fidalgo A., Ilharco L.M., Farinha J.P.S., Martinho J.M.G., Centro de Química-Física Molecular, Instituto Superior Técnico, PT

Novel nanohybrid silica/polymer aerogels were produced by the soft sol-gel process, under subcritical conditions. They are hydrophobic, monolithic, and with improved mechanical properties. These materials may well be the answer to low cost-high performance insulators. [...]

Magnetic Dye-Adsorbent Catalyst: A “Core-Shell” Nanocomposite

Shukla S., Varma M.R., Suresh K.G., Warrier K.G.K., Council of Scientific and Industrial Research (CSIR), IN

A magnetic dye-adsorbent catalyst has been developed which is the modification of the conventional magnetic photocatalyst. It consists of a nanocomposite particle having a “core-shell” structure, with a magnetic ceramic particle as a core and [...]

Development of Melt Blown Electrospinning Apparatus of Isotactic Polyproylene

Watanabe K., Lee K.H., Lee Y.J., Nakamura T., Lee K.H., Lee Y.J., Kim B.S., Kim I.S., Kim K.W., Kim B.S., Kim I.S., Kim K.W., Kim B.S., Kim I.S., Kim K.W., Shinshu University, JP

Melt blown electrospinning is a method of combining melt blown with melt electrospinning. In this study, we developed the multi nozzle melt blown electrospinning machine. The significant point of this method is to use air [...]

Ag-TiO2 Coated Polyurethane Composite Nanofiber Web for Application in the Protection against Chemical and Biological Warfare Agent

Ryu S.-Y., Choi W.H., Ahn C.H., Kwak S-Y, Seoul National University, KR

Threats of chemical warfare (CW) and biological warfare (BW) agents are serious international problems. It is positively necessary to protect humankind against CW/BW agents. The objective in this work is to develop protective clothing that [...]

Thermomechanical Properties of Epoxy Resin MWCNts Nanocomposites

Kanapitsas A., Zois H., Delides C.G., Technological Educational Institute of Lamia Department of E, GR

The main aim of the present work is to study the mechanical and thermal properties of nanocomposite materials based on epoxy resin (ER) matrix reinforced with multi-walled carbon nanotubes (CNTs). The filler content was systematically [...]
