Spontaneous Liquid Flow in Microfluidic Systems by Gradual UV Irradiation of the Hybrid Polymer/TiO2 Nanorods Channels

Athanassiou A., Center for Biomolecular Nanotechnologies @ UNILE, IIT, IT

PMMA coatings enriched with colloidal TiO2 nanorods are found to exhibit a remarkable increase in their water wettability when irradiated with UV laser light. The effect can be completely reversed using successive storage in vacuum [...]

Poly(butyl terephthalate)/oxytetramethylene + oxidized carbon nanotubes hybrids: mechanical and tribological behavior

Brostow W., Broza G., Datashvili T., Kopyniecka A., TUHH, DE

Carbon nanotubes (CNTs) have been used for providing mechanical reinforcement to polymers [1, 2] – as have been other approaches. Much less attention than to mechanics has been paid to improvement of tribological properties of [...]

Silica–Polyacrylate Nanocomposite Pressure Sensitive Adhesives

Shanks R., RMIT University, AU

The aim of this research is to increase cohesion of a PSA by including silica nanoparticles. The silica nanoparticles form reversible agglomerates and bind polymer molecules by adsorption. The adhesive becomes a reversible gel. Under [...]

Fabrication of nanostructured microworms for sensor applications

Yagüe J.L., Dubach J.M., Ozaydin-Ince G., Clark H.A., Gleason K.K., Massachusetts Institute of Technology, US

A novel method to create in vivo sensors for multiple types of ions and molecules is presented. Using initiated Chemical Vapor Deposition (iCVD), a gentle process which preserves functional pendant groups and enables conformal coatings, [...]

Magnetically Induced Drop Movement on Nanorough Micropatterned Nanocomposites

Milionis A., Fragouli D., Anyfantis G.C., Bayer I., Cingolani R., Athanassiou A., Italian Institute of Technology, IT

Hybrid organic/inorganic surfaces are engineered by exploiting photo-lithographically tailored patterns of SU-8 polymer nanocomposites containing 2% wt colloidal nanoparticles of iron oxide. The role of the magnetic nanoparticles has two aspects. The first one is [...]

Controlling pH responsive polymersome assembly

Pearson R., Battaglia G., University of Sheffield, UK

Size is an important parameter in delivery systems. It plays a part in whether a particle avoids filtration, evades immune cell binding and by which internalisation pathways are available. However, it is hard to obtain [...]

Using liquid crystals to improve the performance of luminescent solar concentrator

Debije M., Eindhoven University of Technology, NL

The luminescent solar concentrator (LSC) has been proposed as a cost-effective solution to bring electricity generation from sunlight into the built environment. The basic LSC design consists of a plastic plate containing or topped by [...]

The Effect of Various Binder Additions on the Magnetic Properties of Soft Magnetic P/M Cores

Kim H.-J., Kim K.S., Kim S.I., Kim H.-J., Kim K.S., Kim S.I., Song J-J, Yoon S.C., Kim H.-J., Kim K.S., Kim S.I., Inje University, KR

Recently, there has been a growing demand for soft magnetic materials used in miniaturized electromagnetic devices with high performance, which can be used at a high frequency range. These applications include Switch Moded Power Supply, [...]

Influence of Silica Nanoparticles on the Thermal Transitions and Structure of PHBA-PET Nanocomposites

Miranda F., Acevedo A., University of Puerto Rico, PR

Composite films were produced by direct melt-blending of the polymer with up to 1.5 vol% loadings in a Thermo-Haake MiniLab2 twin-screw extruder. Thermal transitions were determined by differential scanning calorimetry and thermogravimetric analysis. Structure and [...]

Computer Simulation of Graphene-Metal Composite Induced by Radiation

Ilyin A.M., Beall G.W., Texas State University, US

In this paper we have submitted some results of computer simulation and calculations based on the density functional theory of the energy and structural characteristics of some possible kinds of stable complex structural defects in [...]
