  1. 1. Quantification of Swelling in Sealing Materials

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Johanna Möller; Paula Erlandsson; [2021]
    Keywords : elastomer; rubber; gaskets; NBR; EPDM; swelling; diffusion coefficient; polymer technology; Technology and Engineering;

    Abstract : The objective of this study was to quantify swelling in gasket materials to better predict the gaskets life span in heat exchangers. Alfa Laval produces plate heat exchangers, which are a common unit within the process industry. There are different types of plate heat exchangers, and one type is sealed with gaskets. READ MORE

  4. 3. Hall Measurement on Regrown Nanowires

    University essay from Lunds universitet/Fysiska institutionen

    Author : Sudhakar Sivakumar; [2015]
    Keywords : Hall measurement; InGaAs; III-V semiconductor; ballistic; transport properties; mobility; sheet carrier concentration; Physics and Astronomy;

    Abstract : Ternary semiconductor alloys like $In_xGa_{1-x}As$ have lured competing attention in connection to sub-50 nm high performance, low power, planar Complementary Metal Oxide Semiconductor technology. This compound semiconductor owes its popularity to excellent bulk carrier mobility, minority carrier diffusion constant, small bandgap, high electron injection velocity and its capability to take Moore's law beyond silicon platform.

  5. 4. Heating a Plasma to 100 Million Kelvin

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Gunnar Fröberg; Thomas Nygren; [2014]
    Keywords : ;

    Abstract : In this work techniques for heating the fusion reactor ITER to thermonuclear temperatures, over 100 million kelvin, is investigated. The temperature is numerically computed for different heating configurations. The heat leakage is modeled to occur only via diffusion. The diffusion is assumed to be a combination of Bohm and gyro-Bohm diffusion. READ MORE

  6. 5. Comparison of Diffused and Implanted InSb pn-photodiodes Performance

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Ali Asadollahi; [2011]
    Keywords : ;

    Abstract : In this project, two different methods for fabrication of InSb p-n photodiodes were compared. Ion implantation with Mg as a standard way to fabricate InSb p-n diodes was compared to in-diffusion of zinc atoms from the gas phase using a metal organic vapor phase epitaxy (MOVPE) system.
