  2. 16. Integration of Two-Dimensional Materials for Electronics and Photonics

    Author : Arne Quellmalz; Kristinn Gylfason; Frank Niklaus; Cedric Huyghebaert; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Two-dimensional (2D) materials with a thickness on the atomic scale promise to continue the trend of increasing performance in electronics, photonics, and sensing. However, despite record-breaking demonstrations of individual devices, the commercial exploitation of 2D materials is still limited. READ MORE

  4. 17. Methods for availability improvements of a scaling machine system

    Author : Andi Rahadiyan Wijaya; Jan-Gunnar Persson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

    Abstract : Scaling is the process of cleaning loose material from the roof, face and wall of the mine room in underground mining. The purpose of scaling is to make the mine room safe for the next operation. Due to the nature of the task, scaling has been identified as an operation with a high number of accident occurrences.

  5. 18. Strategies for improving kraftliner pulp properties

    Author : Stefan Antonsson; Mikael E. Lindström; Gunnar Henriksson; Mats Johansson; Hans Theliander; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lignin; xylan; kraftliner pulp; mechano-sorptive creep; hygroexpansion; stiffness; fibre shape; fibre width; lignin; xylan; kraftlinermassa; mekanosorptivt kryp; hygroexpansion; styvhet; fiberform; fiberbredd; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Abstract : A large part of the world paper manufacturing consists of production of corrugated board components, kraftliner and fluting, that are used in many different types of corrugated boxes. Because these boxes are stored and transported, they are often subjected to changes in relative humidity. READ MORE

    Abstract : Hydrogen is seen as a key player in leading to a sustainable energy sector and decarbonizing the transport sector. Proton Exchange Membrane Fuel Cells (PEMFCs) consume hydrogen and oxygen to generate water, heat and electricity. READ MORE

  7. 20. The Spatial Distribution of Precipitation in Scania, Southern Sweden. Observations, model simulations and statistical downscaling

    Author : Maj-Lena Linderson; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; physical geography; Geologi; fysisk geografi; Geology; statistical downscaling; atmospheric circulation; spatial distribution; precipitation; Scania; Sweden;

    Abstract : This thesis focusses on the spatial distribution of precipitation within Scania and on its relation with large-scale climate. The spatial distribution of Scanian precipitation was analysed using a dense rain-gauge network of daily measurements. READ MORE
