Organic versus Hybrid Coacervate Complexes: Co-Assembly and Adsorption Properties

Fresnais J., Berret J.-F., Qi L., Chapel J.-P., Castaing J.-C., Laboratoire Matière et Systèmes Complexes, FR

We report the co-assembly and adsorption properties of coacervate complexes made from polyelectrolyte-neutral block copolymers and oppositely charged nanocolloids.

Generalized model for the aggregation rate of colloidal nanoparticles and clusters induced by shear in the presence of repulsive interactions

Lattuada M., Morbidelli M., ETH Zürich, CH

Coagulation of colloidal nanoparticles in the presence of shear is a key step in processing of many particulate materials, polymeric nanoparticles, food products etc. In the case of charged nanoparticles, coagulation is usually carried out [...]

Adsorption of Colloid Gold Nanoparticles on Charged Surface

Tzeng S-D, Luo C-S, Gwo S., Lin K.-J., National Chung Hsing University, TW

Colloid gold nanoparticles have many important applications, such as bio-molecular sensors and electronic devices. To fabricate the devices, one of the most significant processes is to assemble the gold nanoparticles on surface. In this work, [...]

Förster transfer in coupled colloidal type-II and type-I quantum dots

Mourokh L.G., Kuskovsky I.L., Smirnov A.Yu., Matsui H., Queens College, CUNY, US

We examine theoretically resonant non-radiative exciton (Förster) transfer in the system of colloidal core-shell quantum dots (QDs) of different types. In this, the type-II QDs with electrons and holes separated in the real space have [...]

Functionalization of multiwalled carbon nanotubes with _-lactalbumin and _-lactoglobulin

Zhou J., Yang Q., Pan X., Gunasekaran S., University of Wisconsin-Madison, US

The immobilization of proteins on carbon nanotubes is attracting much attention because the resultant hybrid nanomaterials are potentially useful as biomolecular nanosensors [1]. -lactalbumin and -lactoglobulin are the major proteins in whey, the by-products of [...]

High bending stiffness paperboard laminates with reduced weight

Jogikalmath G., Reis L., Soane D., NanoPaper LLC, US

High bending stiffness is desirable in many paper and paperboard applications. This property is often achieved by manufacturing dense, high caliper sheets or boards. In addition to consuming large amounts of pulp, such paperboards or [...]

Novel Hybrid Materials of Cellulose Fibres and Nanoparticles

Small A.C., Johnston J.H., Victoria Univeristy of Wellington, NZ

The combination of organic and inorganic materials provides the opportunity to develop new materials that not only retain the inherent properties of their component precursors but may also exhibit new properties due to the synergistic [...]

Preparation of transparent electrodes based on CNT-s doped metal oxides

Paalo M., Tätte T., Visk U., Lõhmus A., Lõhmus R., Lõhmus A., Lõhmus R., Kink I., University of Tartu, EE

In recent year’s electrically conductive and transparent electrodes has been one of the most important issues in optoelectronics. High price of ITO have set the search for alternative materials into focus. CNT-s has been used [...]

Influence of the crystallite size of BaTiO3 on the dielectric properties of polyester reactive resin composite materials

Schumacher B., Geßwein H., Hanemann T., Haußelt J., Forschungszentrum Karlsruhe, DE

Today’s electric equipment has to be small in dimension and rich in functionality to be successful with the customer. The available surface area on today’s printed circuit boards (PCB) is decreasing as a result and [...]

TiO2-Ag Porous Nanocomposites for Advanced Photocatalytic Processes

Baia L., Baia M., Baia L., Baia M., Vasiliu F., Diamandescu L., Peter A., Cosoveanu V., Danciu V., Babes-Bolyai University, RO

The photo-assisted catalytic decomposition of organic pollutants from water and air by employing titanium dioxide as photocatalysts is a very promising method. TiO2 based aerogels are porous solid materials with high surface area, ultra-low density [...]
