2. 1. Landscapes of Technology Transfer : Swedish Ironmakers in India 1860–1864

   Author : Jan Af Geijerstam; KTH; []
   Keywords : HUMANIORA; HUMANITIES; History of technology; industrial heritage studies; industrial archaeology; technology transfer; diffusion; technological systems; landscapes of technology; iron and steel; charcoal iron; direct and indirect ironmaking; bloomeries; 19th century; indu; Historiska studier av teknik; vetenskap och miljö; History of Science; Technology and Environment;

   Abstract : In the early 1860s three Swedes, Nils Wilhelm Mitander,Julius Ramsay and Gustaf Wittenström, were engaged by theBritish to build and run charcoal-based ironworks in India.These works, the Burwai Iron Works of the British Government inthe case of Mitander and the privately owned Kumaon Iron Worksin the case of Ramsay and Wittenström, were both to bebased on the most modern European technology.

4. 2. Tensile behaviour of mineral-based composites

   Author : Katalin Orosz; Anders Ansell; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

   Abstract : Externally bonded fibre-reinforced polymer (FRP) systems have shown to be a robust and durable way to repair, or strengthen concrete structures. Epoxy, as the most common bonding agent, provides excellent force transfer, and bonds well to the base substrate to the as well as to the strengthening material. READ MORE

5. 3. Stimulating the diffusion of environmental technologies through export

   Author : Wisdom Kanda; Olof Hjelm; Dzamila Bienkowska; Totti Könnölä; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; HUMANIORA; HUMANITIES; Environmental Technology; Technology Diffusion; Export; Internationalisation;

   Abstract : Contemporary environmental problems represent complex societal challenges, and as these problems become increasingly global, the international diffusion of environmental technologies is essential. One way to diffuse technologies internationally is through export. READ MORE

6. 4. Diffusion-Induced Nonlinear Dynamics in Carbon Nanomechanical Resonators

   Author : Christin Edblom; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; mass sensing; graphene; stochastic differential equations; diffusion; carbon nanotubes; resonators; nanoelectromechanical systems; equations of motion; nonlinear dynamics; dissipation; Fokker-Planck equation; noise; nonequilibrium dynamics;

   Abstract : The emergence of nanoelectromechanical systems has enabled the development of sensors capable of detecting mass, charge, force, position, and spin with an unprecedented precision. In particular, the low mass, high resonant frequency, and high quality factor of carbon nanomechanical resonators make them ideal for the creation of a high sensitivity mass sensor. READ MORE

7. 5. Electronic Structure Calculations of Point Defects in Semiconductors

   Author : Andreas Höglund; Susanne Mirbt; Alison Mainwood; Uppsala universitet; []
   Keywords : Physics; electronic structure calculations; point defects; semiconductor; formation energy; equilibrium solubility limit; thermodynamic equilibrium concentration; transfer levels; negative-U; 110 surface; diffusion; activation energy; solar cells; Fysik;

   Abstract : In this thesis point defects in semiconductors are studied by electronic structure calculations. Results are presented for the stability and equilibrium concentrations of native defects in GaP, InP, InAs, and InSb, for the entire range of doping conditions and stoichiometry. READ MORE
