Simulation and Fabrication of Large Area 3D Nanostructures

Bogart K.H.A., El-kady I., Grubbs R.K., Rahimian K., Sanchez A.M., Ellis A.R., Wiwi M., McCormick F.B., J.-L. Shir D., Rogers J.A., Sandia National Laboratories, US

Three-dimensional (3D) nano-structures are vital for emerging technologies such as photonics, sensors, fuel cells, catalyst supports, and data storage. The Proximity-field nanoPatterning1 method generates complex 3D nanostructures using a single exposure and development cycle. Exposure [...]

Fabrication and Characterizations of Ultra Violet Photosensor Based on Single ZnO Nanorod

Lupan O., Chai G., Chow L., University of Central Florida, US

Wide-gap semiconducting metal oxides with nanostructures such as nanorods, nanowires are promising as building nanoblocks in novel devices. Zinc oxide is most widely applied material owing to its characteristics and low cost, radiation hardness, chemical [...]

Optical Nanotrapping Using Illuminated Metallic Nanostructures: Analysis and Applications

Furlani E.P., Baev A., Prasad P.N., University at Buffalo, US

The interest in optical particle manipulation has grown steadily in recent years especially for applications in the biological sciences where the manipulated objects include cells, organelles, and larger molecules. While micron and sub-micron bioparticles can [...]

Study of the ferroelectric properties for PVDF using DFT Theory

Ortíz E., Cuán A., Badillo C., Wang Q., Noreña L., Universidad Autonoma Metropolitana-Azcapotzalco, MX

Polyvinylidene fluoride (PVDF) exhibits piezoelectricity effect. In this work, it is presented a theoretical study of some properties of this material which were calculated by Density Functional Theory (DFT). Among those properties are: polarizability, dipolar [...]

Preparation and characterization of highly porous PVDF nanofibers and yarns

Andrukh T., Few C., Burtovyy O., Burtovyy R., Burtovyy O., Burtovyy R., Luzinov I., Kornev K., Clemson University, US

Unique highly porous Polyvinylidene difluoride (PVDF) nanofibers (Figure 1) of about 50-500 nm in diameter were prepared by electrospinning. Electrospinning setup (Figure 2) allows us to control the nanofiber placement on the gap-type electrodes. In [...]

Novel Approach for Preparation of Organic-Inorganic Hybrid Nanocomposites

Kim I-J., Kwon K.H., Cheil Industries Inc., KR

Novel organic-inorganic hybrid nanocomposites were synthesized through emulsion grafting polymerization in the presence of silica particles coated with methacryloxy(propyl)trimethoxysilane. Well-defined polymer chains were grown from the nanoparticle surfaces to yield individual particles composed of a [...]

Reactive block copolymers as versatile compatibilizers for polymer-clay nanocomposites

Flores-Santos L., González-Montiel A., Baeza-Alvarado M.D., Espinoza-Rodríguez E., Esparza-Hernández P., CID, Centro de Investigación y Desarrollo Tecnológico, S.A. de C.V., MX

It’s well known that silicate-polymer nanocomposites offer a number of significant advantages over traditional silicate-polymer composites, such as increased tensile strength, improved heat deflection temperature and flame retardance, with typically 3-5 wt.% of the nanofiller, [...]

The anti-ultraviolet nano-fibers formed during electrospinning

Lin Y-N., Hsu R-Q., Chang K-M, National Chiao Tung University, TW

In this study, electrospinning is a straightforward method to produce anti-ultraviolet polymer fibers. The new types of anti-ultraviolet nano-fibers were produced by polylactic acid (PLA) and benzophenone. We also used different anti-ultraviolet nano particles (TiO2, [...]

The First-aid strip of copolymer, produced by electrospinning

Lin Y-N., Hsu R-Q., Chang K-M, National Chiao Tung University, TW

In the study of biomimetic material design, mimicking nanostructured thin film components can take the place of the extracellular matrix. The new types of thin film were fabricated by polylactic acid (PLA) and hyaluronic acid [...]

Nanosilicate Filled Poly (vinyl chloride-co-vinyl acetate) and Epoxy Coatings for Steel Corrosion Protection

Allie L., Thorn J., Aglan H., Tuskegee University, US

The corrosion protection of nanosilicate filled poly (vinyl chloride - co - vinyl acetate) (VYHH) and epoxy resins has been studied. Nanosilicate was incorporated into VYHH at 0%, 0.5% and 1.5%wt loadings, and into epoxy [...]
