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 [...]

Silica-alumina composite monoliths with a hierarchical pore structure containing the MFI-type zeolitic films

Pudlo W., Pashkova V., Derewinski M., Jarzebski A.B., Institute of Chemical Engineering, Polish Academy of Sciences, PL

Materials with multimodal hierarchical porosity, containing pore networks in the range of micro-, meso- and macropores, attract considerable attention owing to their widespread application prospects in process industries (catalysts, sorbents), energy conversion and sensors. Here [...]

Thermal and Mechanical Response of POSS coated Nanophased expandable foam core materials

Jones W.D., Rangari V.K., Jeelani S., Tuskegee University, US

A sonochemical technique has been established to coat variations of POSS nanoparticles on expandable microspheres. Thermal analyses results indicate that there is an increase in thermal stability of nanophased foam as compared to the neat [...]

Plasma Treatment of Nanofillers for Polymer Nanocomposites

Ritts A.C., Yu Q., Li H., University of Missouri-Columbia, US

Nanofillers were functionalized with amine groups using low-temperature plasma to enhance dispersion and interfacial tension with Epon 815C resin. The amine groups remained on the coating surface were anticipated to strengthen the interfacial interactions through [...]

Refined coarse-grain modeling of stamp deformation in nanoimprint lithography

Merino S., Retolaza A., Juarros A., Schift H., Sirotkin V., Svintsov A., Zaitsev S., IMT RAS, RU

The inhomogeneous distribution of the residual layer thickness is a vital issue in nanoimprint lithography (NIL). Using the simulation of NIL, this problem can be alleviated by optimizing the stamp geometry and by choosing process [...]

Nanotechnology for Building Security

Elvin G., Green Technology Forum, US

Despite increased vigilance and annual federal anti-terrorism spending in excess of $55 billion, building security remains a major concern for most Americans. For those working in large governmental or institutional buildings, fears are particularly acute. [...]
