  1. 1. Nonlinear rheological characterization of cellulose nanocrystals based systems

    Författare :Sylwia Wojno; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; cellulose; rheo-PLI; CNC; FT-rheology; rheology;

    Sammanfattning : In this thesis, cellulose nanocrystals based systems were investigated using advanced rheological characterization techniques, with a particular focus on nonlinear material response functions and Rheo-PLI (Polarized Light Imaging). Cellulose nanocrystals (CNCs) show enormous potential for many applications, either as material on its own or as renewable reinforcement in polymers. LÄS MER

  3. 2. Lytic polysaccharide monooxygenases for green production of cellulose nanomaterials

    Författare :Salla Koskela; Qi Zhou; Markus Linder; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cellulose; enzyme; CNC; CNF; LPMO; nanocellulose; wood; Biotechnology; Bioteknologi;

    Sammanfattning : Cellulose is the main structural polymer in wood, and its potential in the form of nanomaterial building blocks, nanocelluloses, has now been recognized. Nanocelluloses, including cellulose nanofibers (CNFs) and cellulose nanocrystals (CNCs), have become increasingly important in development of modern sustainable materials. LÄS MER

  4. 3. The p97 ATPase and the Drosophila Proteasome : Protein Unfolding and Regulation

    Författare :Kristian Björk Grimberg; Patrick Young; Neus Visa; Lars Thelander; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; proteasome; ubiquitin; p97; unfolding; regulation; RNAi screen; high-throughput screen; cnc; basic leucine zipper; transcription factors; proteasome inhibition; Molecular biology; Molekylärbiologi; Molecular Biology; molekylärbiologi;

    Sammanfattning : For all living systems, there is a requirement to recycle and regulate proteins. In eukaryotic organisms this is accomplished by the proteasome. The p97 ATPase is another highly conserved and essential complex present throughout the eukaryotic cell. LÄS MER

  5. 4. Inorganic and organic polymer-grafted nanoparticles : their nanocomposites and characterization

    Författare :Carmen Cobo Sanchez; Eva Malmström; Henrik Hillborg; Anna Barros Timmons; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Si-ATRP; ATRP; polyelectrolytes; rGO; aluminium oxide; silica; CNF; CNC; PCL; LDPE; EBA; nanocomposites; matrix-free; extrusion; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Nanocomposites (NCs) have been widely studied in the past decades due to the promising properties that nanoparticles (NPs) offer to a polymer matrix, such as increased thermal stability and non-linear electrical resistivity. It has also been shown that the interphase between the two components is the key to achieving the desired improvements. LÄS MER

  7. 5. A study of process planning for metal cutting

    Författare :Staffan Anderberg; Lars Pejryd; Tomas Beno; Mats Andersson; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process planning; CAPP; CAM; efficiency; performance; green manufacturing; sustainable machining; CNC; Produktionsberedning; effektivitet; grön tillverkning; Industrial engineering and economy; Industriell teknik och ekonomi; Manufacturing engineering; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : Process planning as a function for competitiveness is often neglected. However, as an intermediary between product development and manufacturing, it holds a key function in transforming product specifications and requirements into a producible process plan. LÄS MER
