1. 1. Design of Cellulose-based Materials by Supramolecular Assemblies

   Författare :Tobias Benselfelt; Lars Wågberg; Torbjörn Pettersson; Joseph Schlenoff; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adhesion; adsorption; alginate; assemblies; biodegradable; biomaterials; biopolymers; cellulose; cellulose nanofibrils; CNFs; gas barrier; hemicellulose; interfaces; ion-ion correlation; latex; layer-by-layer; metal-ligand complexes; montmorillonite; multivalent ions; packaging; PISA; polyelectrolyte multilayers; polyelectrolytes; polysaccharides; RAFT; renewable; specific ion effects; supramolecular; surfaces; sustainable; thin films; water-resilient; xyloglucan; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Sammanfattning : Due to climate change and plastic pollution, there is an increasing demand for bio-based materials with similar properties to those of common plastics yet biodegradable. In this respect, cellulose is a strong candidate that is already being refined on a large industrial scale, but the properties differ significantly from those of common plastics in terms of shapeability and water-resilience.

3. 2. Adsorption of Metallic Ions onto Chitosan : Equilibrium and Kinetic Studies

   Författare :Martha Benavente; Joaquín Martínez; Olle Wahlberg; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adsorption; biosorption; chitin; heavy metals; isotherm; kinetic models; mining; speciation; water treatment; Chemical engineering; Kemiteknik;

   Sammanfattning : Equilibrium isotherms and the adsorption kinetics of heavy metals onto chitosan were studied experimentally. Chitosan, a biopolymer produced from crustacean shells, has applications in various areas, particularly in drinking water and wastewater treatment due to its ability to remove metallic ions from solutions.

4. 3. Sustainable recycling of Li-ion batteries

   Författare :Jędrzej Piątek; Adam Slabon; Tetyana Budnyak; Reza Younesi; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; batteries; recycling; metal recovery; adsorption; electrochemistry; oorganisk kemi; Inorganic Chemistry;

   Sammanfattning : Lithium-ion batteries (LIBs) play a key role in today’s energy storage sector, finding applications in everyday use electronic devices, like smartphones, laptops or electric vehicles. Despite very good properties, such as high electric capacity and high number of charge-discharge cycles, eventually each battery in the world will be disposed and stored in a landfill, waiting for the opportunity to be recycled.

7. 5. Synthesis and applications of low silica zeolites from Bolivian clay and diatomaceous earth

   Författare :Javier Gustavo Garcia Mendoza; Johanne Mouzon; Niklas Hedin; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Zeolites; Synthesis; clay; diatomite; adsorption; ion exchange; Chemical Technology; Kemisk teknologi;

   Sammanfattning : The aim of the present work was to develop synthesis routes to produce synthetic zeolites with industrial attractiveness from non-expensive Bolivian raw materials, such as clays and diatomite. In particular, the work was focused on the synthesis of low-silica zeolites with the LTA and FAU structures. LÄS MER
