Acoustic – Electromagnetic Transformation in Magnetic Nanofluids

Sokolov V.V., Moscow State University of Instrument Engineering and Computer Science, RU

Here is examined the acoustic – electromagnetic transformation accompanying the propagation of sound wave through a magnetic nanofluid.The magnetic nanofluid was placed in the cylindrical resonator. An external magnetic field was applied along an axis [...]

Microstructures design of the assembly of monodisperse polystyrene microspheres via alternative current electric field

Ling L.T, Zhang J., Wang C.F., Chen S., Nanjing Tech University, CN

The assembly of monodisperse polystyrene microspheres under alternative current electric field was applied as a model system to study the assembling mechanism for nanomaterials. The microspheres of about 1-2 μm in diameter enable us to [...]

Thermo-plasmonics in self-organized materials

De Sio L., Placido T., Comparelli R., Curri L., Tabiryan N., Bunning T., Beam Engineering for Advanced Measurements Company, US

Conversion of near infrared radiation into heat, controlled at the nanoscale, is achieved and detected by exploiting the localized plasmonic resonance (LPR) of gold nanorods (GNRs) trapped in thermosensitive self-organized materials such as Liquid Crystals [...]

Bulk-Size Transparent Gadolinium Oxide-Polymer Nanocomposites for Gamma Ray Scintillation

Chen Q., Cai W., Hajagos T., Kishpaugh D., Liu C., Cherepy N., Dooraghi A., Chatziioannou A., Payne S., Pei Q., University of California, Los Angeles, US

Heavy element loaded polymer composites have long been proposed to detect high energy X- and -rays upon scintillation. The previously reported bulk composite scintillators have achieved limited success because of the diminished light output resulting [...]

Formation of complex nanoparticles from a spherical protein (BSA) and two polycations (PDL with two molecular weights) using coacervation method of the polyelectrolytes

Maldonado L., Sadeghi R., Kokini J., Purdue University, US

Complex nanoparticles (CNPs) were formed by mixing Bovine Serum Albumin (BSA) and Poly-D-Lysine with low (LMW-PDL) and high molecular weights (HMW-PDL). Since BSA and both PDL biopolymers in neutral and alkaline pHs are oppositely charged [...]

Ordered Structure Pattern on Polymeric Surface

Liu T.H., Huang C-L, Lee S., National Tsing Hua University, TW

The wrinkle pattern on polymeric surface is explained by chemical stresses. We solved the anomalous transport equation to obtain the concentration of solvent in polymeric film. The anomalous transport consists of case I and case [...]

Computer modeling of complex block copolymer micelles with metal-ligand self-assembly

Wang Z., Dormidontova E.E., University of Connecticut, US

For many applications of nanostructured materials it is essential to understand the principles controlling self-assembly, which is often a challenging task due to the heterogeneity of building blocks, (different chemical nature, size, shape, deformability, etc.) [...]

A Novel Application Technique for Polymer Nanofibers in the Construction Industry

Araya A.L., Vargas R.F., Cuevas R., Chaves J.S., Instituto Tecnologico de Costa Rica, CR

During 2008 about 3 billion tons of concrete were produced all over the world, making it the most important industrial product produced in the history of mankind. Therefore, any technological improvement in this product will [...]

A Study of the Effect of Al2O3 Nanoparticles on the Cure behavior of Bisphenol A Epoxy Resin

Halim S.F., National Institute for standards, EG

Epoxy resins based composites are used as laminates for printed circuits boards, aerospace, ballistic and engineering hardware components, automotive parts, electrical components and rehabilitation products. However, some of its interior characteristics such as thermal stability, [...]

Toughening of epoxy matrix fiber reinforced composites with two different nanorubber systems for Advanced Industrial Applications

Ozdemir N.G., Zhang Tao, Kingston University London, UK

Toughening of commercial resin matrices with nano carboxylated acrylonitrile butadiene rubber (CNBR-NP) and acrylonitrile butadiene rubber (NBR-NP) was investigated. Different processing techniques have been used. The rheological, cure, mechanical and morphological characteristics of both systems [...]
