Utilization of ceramic wastes as pozzolanics materials

Irassar E., Rahhal V., Tironi A., Trezza M., Pavlík Z., Pavlíková M., Pavlíková M., Jerman M., Cerný R., Universidad Nacional del Centro de la Provincia de Bs.As., AR

The possible applicability of waste ceramic powder as partial portland cement replacement in concrete production is studied in this paper, due to rapid increase of concrete as building material. The cement industry alone is estimated [...]

Alumina extraction from fly ash by the MgO sintering method: Waste reduction and utilization

Zhao L., Sun Q., Wang B., Wang X., Wang B., Wang X., Xiao Y., Yu G., Liu X., Zhang Z., National Institute of Clean-and-low-carbon Energy (NICE), CN

In recent years, many methods for the alumina extraction from fly ash have been tested, developed and demonstrated in China. Generally, alkali sintering methods are more easily deployed than acid leaching methods, but it is [...]

Utilization of Industrial Waste as a Composite Cementing Materials

Khan M.I., King Saud University, SA

The deterioration in concrete structures exposed to harsh environments has become a matter of global concern. The requirement for high durability in concrete structures cannot be easily achieved using ordinary portland cement. Therefore, new materials [...]

Applications of Enzymatic Saccharification Residues as a Fully Biobased Adhesive

Hafez I.H., Yang H., Tze W.T.Y., University of Minnesota, US

When woody biomass is enzymatically treated to release from its polysaccharide components fermentable sugars for bio-alcohols and other chemicals production, it typically leaves behind in the waste stream solid residues that are rich in lignin. [...]

Rheological performance and NMR structure investigation of ultrasound crumb rubber modified bitumen

Filippelli L., Antunes F.E., Gentile L., Spadafora A., Ranieri G.A., Rossi C.O., University of Calabria, IT

Rubber from tyres is a waste material with a highly valuable constituents. the introduction of crumb rubber in the production of asphalt rubber (AR) mixes for road pavements should be considered as a sustainable technology [...]

The High Performance Thermal Building Insulation Materials of Beyond Tomorrow – From Concept to Experimental Investigations

Jelle B.P., Gao T., Sandberg L.I.C., Tilset B.G., Grandcolas M., Gustavsen A., SINTEF Building and Infrastructure / Norwegian University of Science and Technology (NTNU), NO

A major key strategy to achieve energy-efficient buildings is the development of high performance thermal building insulation materials, also often called superinsulation. A possible and promising way to reach these advanced insulation materials is to [...]

Electrospun Nanocomposite Nerve Guidance Conduits for Peripheral Neural Regeneration

Zhu W., Zhang L., The George Washington University, US

A novel tissue engineered scaffold was fabricated by electrospinning and electrospraying techniques, which possesses highly aligned poly-ε-caprolactone (PCL) microfibrous framework and adjustable neurotropic factor embedded poly (D, L-lactide-co-glycolide) (PLGA) nanospheres. Scanning electron microscope revealed the [...]

Polymer Based Continuous Offset Printing

Mead J., Barry C., University of Massachusetts-Lowell, US

Polymeric materials have tremendous potential for nano and micro-structured products because of their fabrication ease and wide property range. The fabrication processes for polymers are cost-effective and rapid. This work presents novel manufacturing approaches for [...]

Green Chemistry of Carbon Nanomaterials

Basiuk E.V., Basiuk V.A., Basiuk E.V., Basiuk V.A., Universidad Nacional Autonoma de Mexico, MX

The global trend of searching for ecologically friendly, ‘green’ chemical processes manifested itself in the chemistry of carbon nanomaterials, in particular, in the development of techniques for their chemical (both covalent and noncovalent) modification. Our [...]

Advancements in Microelectronics-Grade Carbon Nanotube Materials for NRAM® Device Manufacture and Analysis of Carbon Nanotube Mass in End User Devices

Lamb J.E., Gibbons S., Trichur R., Jiang Y., Mangelson K., Kremer K., Janzen D., Brewer Science, Inc, US

Providing materials for use in semiconductor manufacturing is challenging due to the extreme quality levels required for low metal ion and defect levels. This challenge is much greater for suppliers of materials containing long, high-aspect-ratio [...]
