  1. 1. 3D Printing Hydrogel Artificial Muscles and Microrobotics

    University essay from KTH/Kemiteknik

    Author : Malin Alterby; Emily Johnson; Anton Jonason; Denize Svensson; [2023]
    Keywords : 3D printing; MXene; CNT; CNF; hydrogel; actuator;

    Abstract : The purpose of this lab was to investigate the printability of cellulose nanofiber/carbon nanotubes, their functions as actuators, and to compare these properties with MXene/nano cellulose gels. Data on MXene/nano cellulose gel was obtained from previous research made by Hamedi labs. READ MORE

  3. 2. Enhancement of Phenol Formaldehyde Adhesive with Crystalline Nano Cellulose

    University essay from Linnéuniversitetet/Institutionen för skog och träteknik (SOT)

    Author : Johan Ekstrand; [2019]
    Keywords : Nano Cellulose; Fibrillated cellulose; Wood Adhesive; Shear strength; Adhesive Enhancement; Formaldehyde adhesive; Phenol Formaldehyde;

    Abstract : Abstract The wood industries to this day use almost exclusively petroleum derived adhesives that are based mainly on the reaction of formaldehyde with urea, melamine or phenol. These adhesives have low cost and good adjustable properties which makes it hard for bio-based alternatives to compete. READ MORE

  4. 3. Lunar Light House

    University essay from Lunds universitet/Institutionen för arkitektur och byggd miljö

    Author : Monika Lipinska; [2018]
    Keywords : architecture; space; space architecture; moon; lunar; light house; cellulose; nano-cellulose; moon base; lunar outpost; Arts and Architecture;

    Abstract : The Lunar Light House project was developed to provide a novel system of protection against cosmic radiation specifically for a surface Lunar base. It’s main target was to find a technical solution which would allow for more freedom in shaping the base structure and also potentially for introducing natural sun light. READ MORE

  5. 4. Carboxylated Cellulose Nanocrystals Extraction from Kraft Pulp Using Ammonium Persulfate as Low Cost Source & Sustainable Method for High Quality Flexible Packaging Bio-coating

    University essay from Lunds universitet/Förpackningslogistik

    Author : Gerald Perry Estavillo Marin; [2015]
    Keywords : affordable CNC extraction; high quality CNC; sustainable packaging; FT-IR; TEM; XRD; contact angle; transparency; haze; optical properties; food packaging; bio-packaging; bio-coating; plastics; PET film; polyethylene terephthalate; Kraft CNC; Kraft pulp; cotton CNC; oxygen barrier; nanocellulose crystals; ammonium persulfate; CNCs; cellulose nanocrystals; Chemistry;

    Abstract : One of the leading challenges presented in 21st century for packaging industry is to address the growing environmental problems related to non-renewable flexible packaging. This leads to new growing interest in bio-based materials, among them cellulose nanocrystals (CNCs), which have already shown good performance in improving anti-fog and oxygen & water vapor barrier properties when applied to flexible film.

  6. 5. Mechanical properties of materials made of nano-cellulose

    University essay from KTH/Hållfasthetslära (Inst.)

    Author : Denoyelle Thibaud; [2011]
    Keywords : nano-cellulose; paper mechanics;

    Abstract : Recent experimental findings have demonstrated great mechanical properties of nanopaper compared to ordinary paper. In this work, we have studied the formation of the elastic modulus of paper. Our goal was to investigate the contribution of fibers, fiber bonds and network structure. READ MORE
