2. 1. Two-dimensional Nanocomposites Based on Cellulose Nanofibrils and Graphene Oxide

   Author : Hanieh Mianehrow; Lars Berglund; Aji Mathew; KTH; []
   Keywords : Cellulose nanofibrils; graphene oxide; orientation; reinforcement; oxygen barrier; bio-nanocomposite; moisture; molecular adhesion; interfacial shear strength.; Nanocellulosa; grafenoxid; orientering; förstärkning; syrebarriär; bionanokomposit; fukt; molekylär adhesion; skjuvhållfasthet hos gränsytan.; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Abstract : Two-dimensional (2D) nanocomposites based on cellulose nanofibrils (CNF) and 2D nanomaterials are of interest as sustainable materials combining functional and structural properties. To achieve reinforcement effects from 2D nanomaterials, their orientation and dispersion state in the CNF matrix are important. READ MORE

4. 2. Heat transfer phenomena and mould flux lubrication in continuous casting of steel

   Author : Akira Yamauchi; KTH; []
   Keywords : Heat Transfer; Thermal Conductivity; Contact Resistance; Mould Flux; Solidification; Lubrication; Infiltration; Friction; Shear Stress; Modeling; Crystallization; Rupture Strength; Solidus; High-Speed Casting; Viscosity; Elasticity; Uniform Cooling;

   Abstract : Overall thermal resistance of the mould flux was measured tomake clear the influence of the mould flux properties on theheat transfer behavior in continuous casting, especiallythermal conductivity and the formation of air gaps in thisstudy. From the investigation of the effect of the mouldsurface temperature and physical properties of the mould fluxon heat transfer through the flux film, following knowledge hasbeen obtained. READ MORE

5. 3. Integrated biomechanical, electronic and topographic characterization of titanium dental implants

   Author : Johanna Löberg; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Surface roughness parameters; 3D-SEM; AFM; Interfacial shear strength; Impedance spectroscopy; Cyclic voltammetry; SBF; MG-63; TiO2-nanoparticles;

   Abstract : Titanium dental implants are medical devices used to restore the function entailed with the loss of one or several teeth. To obtain successful function over long periods, the dental implants must be sufficiently anchored in the bone to withstand the forces induced by for example chewing. READ MORE

6. 4. Computational studies of graphene and single walled carbon nanotube growth and carbonaceous polymeric nanocomposites

   Author : Shayesteh Haghighatpanah; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Graphene; functionalization; carbon nanotube; Monte Carlo; tight binding; polyacrylonitrile; polyethylene; molecular mechanics; molecular dynamics.;

   Abstract : Graphene and single walled carbon nanotube (SWNT) has attracted a lot of attention in different fields of science due to its unique electrical, mechanical, and optical properties. Controlling the growth of graphene and SWNT is a very topical subject and critical for producing material with desired properties since their properties are highly dependent on their atomic structure and it is often desirable that the material contains very few or (if possible) no defects.

7. 5. STRUCTURAL RETROFITTING OF CONCRETE BEAMS USING FRP - Debonding Issues

   Author : Yasmeen Obaidat; Byggnadsmekanik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : A 3D nonlinear finite element analysis modelling framework was developed for simulating the behaviour of beams retrofitted with fibre reinforced polymer (FRP). The ABAQUS program was used for this purpose. Concrete was modelled using a plastic damage model. READ MORE
