  1. 1. MODELING AND OPTIMIZATION OF WASHING MACHINE VIBRATION DYNAMICS DURING SPINNING

    Author : Thomas Nygårds; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Semi-active control; Vibration dynamics; Experiment; Washing machine; Modeling; Optimization; Magnetorheological damper.; Suspension system; Spinning;

    Abstract : A washing machine as a product is familiar to almost everyone in all developed countries. Thisthesis deals with the dynamics of modern washing machines of household type. READ MORE

  2. 2. Air-gap spinning of lignin-cellulose fibers

    Author : Jenny Bengtsson; Chalmers University of Technology; []
    Keywords : cellulose; carbon fibers; ionic liquid; lignin; air-gap spinning;

    Abstract : Co-processing of lignin and cellulose, the two main constituents of wood, has previously been identified as a potential route for the production of inexpensive and bio-based carbon fibers. The first step in this process is to spin a precursor fiber. READ MORE

  3. 3. Cellulose processing in ionic liquid based solvents

    Author : Carina Olsson; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; esterification; cellulose; NMR spectroscopy; solution spinning; dissolution; ionic liquids; cellulose derivatives; rheology; crystallinity;

    Abstract : As the most abundant polymer in nature, cellulose has an undisputed role among the raw materials to be used in a sustainable future. From its native form, in wood or straw, cellulose can be processed into products such as paper and board. READ MORE

  4. 4. Coagulation of Cellulose: from Ionic-Liquid Solution to Cellulose Nanostructure

    Author : Artur Hedlund; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; MEDICAL AND HEALTH SCIENCES; Wet Spinning; Cellulose; Ionic Liquids; Diffusion; Coagulation; Nonsolvent;

    Abstract : Abstract A linear chain of glucose monomers, cellulose, provides the structural reinforcement of the cell walls of plants and constitutes almost half of their dry mass. Wood and other plant-based raw materials are processed on a large industrial scale to isolate the cellulose, which is then dissolved. READ MORE

  5. 5. Rapid solidification behaviour of Fe and Al based alloys

    Author : Sathees Ranganathan; Hasse Fredriksson; Zhongyun Fan; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rapid solidification; Melt spinning; Metastable phases; Fe based alloys.; Metallurgical process and manufacturing engineering; Metallurgisk process- och produktionsteknik;

    Abstract : Rapid solidification experiment on Fe-Cr-Mo-Mn-Si-C alloy was performed to investigate metastable phases formed during the solidification. A wide range of cooling rate was used to analyse the sample from melt spinning technique (~107 K/s) to water quenching method (~102 K/s). READ MORE
