1. 1. Protein-based hydrogel electrolytes for stretchable Zn-ion batteries

   Master-uppsats, Linköpings universitet/Laboratoriet för organisk elektronik; Linköpings universitet/Tekniska fakulteten

   Författare :Lovisa Byström; [2023]
   Nyckelord :Hydrogel; gelatin; kappa-carrangeenan; Zn-ion battery; Kemisk biologi; Kemisk biologi;

   Sammanfattning : Stretchable aqueous-based Zn-ion batteries have shown promise as a sustainable and safe energy storage system for wearable electronics used in healthcare, sports, soft robotics, and prosthetics. A battery consists of the active electrode, electrolyte, current collector, and encapsulation. LÄS MER

3. 2. 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

4. 3. Modified cellulose synthesized by different deep eutectic solvents as an additive in paper making process

   Master-uppsats, Karlstads universitet

   Författare :Shiniar Said Saleh; [2023]
   Nyckelord :green chemistry; dry strength additives; deep eutectic solvents; sodium periodate oxidation; charge density; dewatering; mechanical strength.;

   Sammanfattning : The environmental concerns that come with the currently used traditional papermaking process where petroleum-based additives are used, has tempted researchers to study “green” additives by introducing environmentally friendly modifications of cellulose as an additive in the papermaking process. This thesis will spin further on that by producing additives with different charge densities and focus on to incorporate an etherification reaction into potentially greens systems based on non-toxic and readily biodegradable deep eutectic solvent (DES).

5. 4. Signal amplification in a microfluidic immunoassay system via Binding Oligo Ladder Detection : Applying the Exazym® signal amplification to the Gyrolab® platform

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för farmaci

   Författare :Daniel Wiman; [2023]
   Nyckelord :immunoassay; ultra-sensitive; signal amplification; Gyrolab; Exazym; high sensitivity; microfluidics; BOLD amplification; nucleic acid polymerisation;

   Sammanfattning : Immunoassays are analytical methods that use the highly specific binding of antibodies in order to detect and quantify an analyte. The technique has become a staple in modern biopharmaceutical research and diagnostics, however the measurement of biomarkers like dysregulated cytokines require ultra-sensitive immunoassays that can detect molecules at sub pg/mL concentrations.

7. 5. Baskatjoner i yt- och grunt grundvatten i Forsmarksområdet : Kontroller, trender och relation till slutförvaret av använt kärnbränsle

   Kandidat-uppsats, Linnéuniversitetet/Institutionen för biologi och miljö (BOM)

   Författare :Jimmy Svensson; [2022]
   Nyckelord :Base cations; Forsmark; trends; bentonite clay; Baskatjoner; Forsmark; trender; bentonitlera;

   Sammanfattning : Svensk Kärnbränslehantering AB beslutade 2009 att bygga ett slutförvar av använt kärnbränsle i anslutning till kärnkraftverket i Forsmark. Tekniken för slutförvaret går ut på att omge kapslarna med bentonitlera som skydd mot vatten och bergsrörelser. LÄS MER
