1. 1. Fabrication of battery separator by coating with sulfonated cellulose nanofibrils on kraft paper and inkjet paper substrates : Tillverkning av batteriseparator genom bestrykning med sulfonerad cellulosananofibriller på kraft papper och bläckstråle papper substrat

   Master-uppsats, Karlstads universitet/Avdelningen för kemiteknik

   Författare :Forat Alshogran; [2023]
   Nyckelord :modified nanocellulose; coating; battery separator; contact angle; mechanical strength; permeance; ionic conductivity;

   Sammanfattning : Modified nanocellulose have distinctive qualities and have drawn a lot of interest from a variety of fields. It is a natural, sustainable product that is manufactured from plant-based materials like wood and other renewable resources. It is also biodegradable. LÄS MER

3. 2. Time to ignition for wood covered with ZnO : A laboratory and theoretical study if ZnO can enhance time to ignition for wood exposed to radiation in the cone calorimeter

   Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Författare :Olina Öhrn; [2023]
   Nyckelord :ZnO; zinc oxide; cone calorimeter; wood; reaction-to-fire;

   Sammanfattning : In recent years, interest in sustainability and being environmentally friendly has increased. Wood is a durable and renewable building material, which is becoming more common in the constructions industry. In 2002, the government in Sweden adopted a national strategy to promote an increased use of wood in buildings. LÄS MER

4. 3. Improvement and verification of a pin-on-disc tribometer with variable speed and load

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Valentine Lin; [2023]
   Nyckelord :tribometer; friction; tribometer; friktion;

   Sammanfattning : The use of threaded fasteners can be found throughout the manufacturing industry due to their simplicity. When tightening a threaded fastener, the goal is to reach a desired clamping force. However, the clamping force is not directly measurable in production environments and the tightening torque is instead used to estimate the clamping force. LÄS MER

5. 4. Development of chitosan nanocomposite coatings for visible-light photocatalytic antiviral applications

   Master-uppsats, KTH/Tillämpad fysik

   Sammanfattning : 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

7. 5. Prussian White In Sodium- Ion Batteries : An evaluation of organic and inorganic coatings on active material particles

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Philip Jansson; [2021]
   Nyckelord :Sodium-ion batteries; Prussian White; Coating; Surface engineering; Zinc oxide; Polyaniline; Natriumjonbatterier; Berlinervitt; Beläggning; Ytmodifiering; Zinkoxid; Polyanilin;

   Sammanfattning : Emerging markets in electrochemical energy storage, such as stationary grid storage, coupled with future concerns over the availability of lithium, places sodium-ion battery (SIB) technologies at a unique position to enter the market as a commercially viable alternative. Current shortcomings in the performance of cathode materials in SIBs would necessarily need to be addressed if this technology is to compete with existing commercial lithium-ion battery counterparts.
