   Abstract : Low dimensional nanostructures of zinc oxide (ZnO), cupric oxide (CuO), and their composite nanostructures possess remarkable physical and chemical properties. Fundamental understanding and manipulation of these unique properties are crucial for all potential applications. READ MORE

6. 4. Sensing capability of nanomodified Portland cement composites

   Author : Thanyarat Buasiri; Andrzej Cwirzen; Karin Habermehl-Cwirzen; Jan Olek; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sensing cementitious composites; nanomodified Portland cement; Carbon nanofibers; CNF; piezoresistive materials; sensor; cement-based sensor; self-monitoring; sensing capability; Byggmaterial; Building Materials;

   Abstract : Sensing cement-based composites refer to composites that have sensing functionality that can measure several physical and chemical parameters. Sensing cement-based composites are fabricated by incorporating some functional fillers, such as conductive fibers (CFs), carbon nanofibers (CNFs), carbon nanotubes (CNTs), and graphene, into conventional concrete.

7. 5. Inelastic behavior of polymer composites

   Author : Konstantinos Giannadakis; Marino Quaresimin; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

   Abstract : In the present thesis, the inelastic behavior of polymer composites is investigated. This investigation concerns three fields of study; time dependent behavior during the lifetime of the composite material, influence of micro-damage on its overall mechanical performance and development of chemical shrinkage strains during the curing process.
