  1. 1. Glyoxylic-Modified Lignin for Synthesis of Smart Elastomer and Composite Materials

    University essay from KTH/Tillämpad fysik

    Author : Xinyi Wei; [2023]
    Keywords : Lignin; lignin-based elastomer; nanocomposites; Lignin; ligninbaserad elastomer; nanokompositer;

    Abstract : Sustainable development has become a global goal and the utilization of bioresources is a key way to achieve this crucial goal. Glyoxylic acid-functionalized lignin (GA-lignin) is one of the novel lignin derivatives extracted from beech wood (hardwood) and has great potential to be an industrially important bioresource.

  5. 4. Printed transparent conducting electrodes based on carbon nanotubes (CNTs), reduced graphene oxide (rGO), and a polymer matrix.

    University essay from Umeå universitet/Institutionen för fysik

    Author : Md Mazharul Islam; [2019]
    Keywords : CNTs; GO; rGO; PVP;

    Abstract : The main focus of this project was to prepare transparent and conductive electrodes (TCEs). TCEs were made out of multi-walled carbon nanotubes (MWCNTs), reduced graphene oxide (rGO), and polyvinylpyrrolidone (PVP). READ MORE

  6. 5. Nano-Graphene Oxide Surface-Functionalized Poly(e-caprolactone) Scaffolds with Drug Delivery Capability

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Yao Jenevieve Linell; [2018]
    Keywords : Poly e-caprolactone PCL ; aminolysis; graphene oxide; tissue scaffolds; ciprofloxacin;

    Abstract : Grafenoxid (GO) ar en lovande kandidat som nano-tillsats i medicinska byggnadsstallningar for benregenerering. GO kan forbattra den biologiska kompatibiliteten och osteogena prestandan hos polymerbaserade byggstallningar, och ocksa vasentligt bidra till forbattringen av materialets mekaniska egenskaper.
