11. Evaluation of electrospun lignin/polyvinyl alcohol/cellulose nanofiber mats
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : Polymeric electrospun nanofiber mats have recently emerged as a promising alternative to conventional wound dressings for non-healing wounds. Its large surface area, porosity and scalability are only a few of the promising characteristics of electrospun nanofibers. LÄS MER
12. Technical Lignin Characterization of Acacia crassicarpa and Eucalyptus Hybrids
Master-uppsats, KTH/Träkemi och massateknologiSammanfattning : Lignin är en av de vanligaste naturliga råvarorna på jorden och finns mestadels i trä. Nuförtiden är valoriseringen av lignin en av processutvecklingarna för teknologier inom massa- och pappersindustrin. Denna utveckling syftar till att öka värdet av lignin. LÄS MER
13. Lignin/Carbon Fibre Composites
Kandidat-uppsats, KTH/KemiteknikSammanfattning : The market is in great need of more environmentally friendly alternatives to fossil-based composite materials to obtain a more sustainable future. Lignin is the second most common biopolymer and is a byproduct in the pulping and paper industry. LÄS MER
14. Comparative analysis of different pyrolysis techniques by using kraft lignin : Jämförelse mellan olika pyrolys metoder
Master-uppsats, Karlstads universitetSammanfattning : This thesis presents a comparison analysis between various pyrolysis techniques performed on kraft lignin. Numerous literature studies of pyrolysis techniques performed on kraft lignin are reviewed and analysed where different operation temperatures, catalysts and different heating methods are used to pyrolyze kraft lignin.

15. Development of magnetic lignin nanoparticles from low-molecular-weight eucalyptus and spruce lignin fractions
Kandidat-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Sammanfattning : Lignin is one of the most common biopolymers in the world. Together with cellulose andhemicellulose it constitutes the fibers in the wood. It has a high molecular weight due to its complexstructure consisting of crossed-linked phenolic monomers and is concatenated with different types ofcarbon and ether bonds. LÄS MER
