1. Evaluating the feasibility of chitosan as an adhesive for wood laminates and as a matrix for transparent wood
Master-uppsats, KTH/Fiber- och polymerteknologiSammanfattning : En av grundpelarna i alla hållbara system är införandet av en cirkulär ekonomi, som främjar återanvändning och återvinning av material. Plast är en av i utmaning i detta avseende på grund av den stora produktionsvolymen variation i sorter och långsamma nedbrytn. LÄS MER
2. Investigation of acidic chemical recycling of poly(acetal-ester)s
Magister-uppsats, Lunds universitet/Centrum för analys och syntesSammanfattning : Plastic recycling is a very relevant topic from both environmental and economic viewpoints. Chemical plastic recycling is a logical solution to the plastic problems, which shows the potential to reduce plastic waste and carbon emissions from burning the plastics. LÄS MER
3. Chemical modification of starch in order to get thermoplastic properties
Kandidat-uppsats, KTH/MaterialvetenskapSammanfattning : There are numerous advantages of replacing traditional non-biodegradable synthetic plastics with bio-based plastics. Starch is globally available, cheap, renewable, and biodegradable. However, starch has a poor product performance and is relatively difficult to process, as conventional melt processing techniques cannot be used. LÄS MER
4. Development of chitosan nanocomposite coatings for visible-light photocatalytic antiviral applications
Master-uppsats, KTH/Tillämpad fysikSammanfattning : During the global pandemic of coronavirus, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak, the world was desperately searching for simpler yet more effective solutions to stop the spread of coronavirus (COVID-19). Since no one was prepared for the fast spread of such a contagious virus, there was a shortage of proper protective solutions to stop the spread. LÄS MER
5. Lignin in Cosmetics: State of the Art : Discerning the value of lignin in the cosmetic industry
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Industriell teknik; Uppsala universitet/Institutionen för medicinsk biokemi och mikrobiologiSammanfattning : This study was carried out at the Department of Nanotechnology and Functional Materials,Uppsala University, one of several places where the interest of lignin in cosmetics is constantly growing. The functionalities of lignin have been studied to a great extent revealing its potential as a natural biopolymer to serve as a replacement for environmentally hazardous components in cosmetic formulations, namely UV-filters in sunscreens.
