  1. 1. Cellulose nanocrystals functionalized cellulose acetate electrospun membranes for adsorption and separation of nanosized particles

    University essay from Luleå tekniska universitet/Materialvetenskap

    Author : José Ignacio Del Río De Vicente; [2021]
    Keywords : Electrospinning; Cellulose Nanocrystals; Filtration; Adsorption; Cellulose Acetate Fibers;

    Abstract : Filtration and separation technologies remain as one of the biggest challenges humanity currently faces. The separation of different elements such as bacteria, viruses, heavy metals, particles, and chemical agents require the development of multifunctional membranes. READ MORE

  4. 3. Evaluation of cellulose nanocrystal alignment in oriented electrospun fibers

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Bermet Kerim Kyzy; [2017]
    Keywords : Electrospinning; alignment; cellulose nanocrystals;

    Abstract : Electrospinning is a fiber production method that has gained a special attention due to the simple setup and potential for the industry scale up to produce nanoregime polymer fibers. However, electrospun fibers have relatively poor mechanical properties, which could be improved by introducing reinforcing agents. READ MORE

  5. 4. Single-molecule X-ray free-electron laser imaging : Interconnecting sample orientation with explosion data

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Christofer Östlin; [2014]
    Keywords : X-ray; free-electron laser; XFEL; diffraction analysis; structure determination; nanocrystal; molecular dynamics; GROMACS; biomolecular imaging; ubiquitin; trajectory; explosion;

    Abstract : X-ray crystallography has been around for 100 years and remains the preferred technique for solving molecular structures today. However, its reliance on the production of sufficiently large crystals is limiting, considering that crystallization cannot be achieved for a vast range of biomolecules. READ MORE

  6. 5. Fabrication and Optical Properties of ZnO Nanocrystal/GaN Quantum Well Based Hybrid Structures

    University essay from Tunnfilmsfysik; Tekniska högskolan

    Author : Kuo Chieh-Yi; [2012]
    Keywords : ZnO; GaN; Hybrid Structure;

    Abstract : Optical properties of hybrid structures based on zinc oxide nanocrystals (NCs) and Gallium Nitride quantum well (QW) has been studied. The ZnO NCs thin films on the top of GaN QW structures were fabricated using spin coating. The surface morphology was characterized by scanning electron microscopy (SEM). READ MORE
