   Sammanfattning : Hydrothermally treated biomass could not only be used as a fuel or a fertilizer but it can also be refined into high-value products. Activated carbons are one of those. LÄS MER

3. 2. Catalytic pyrolysis of lignin to produce fuels and functional carbon materials

   Författare :Tong Han; Weihong Yang; Pär Jönsson; Anker Jensen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lignin; Catalytic Pyrolysis; Biooil; Hydrogen; Magnetic Activated Carbon; Lignin; katalystisk pyrolys; bioolja; vätgas; magnetiskt aktiverat kol.; Teknisk materialvetenskap; Materials Science and Engineering;

   Sammanfattning : Development of renewable energy carriers and green adsorbents is an essential step in creating a fossil-free and toxin-free future of the world. Lignin is the second highest component of biomass and the only renewable resource of aromatics in nature. LÄS MER

4. 3. Sustainable porous organic materials : Synthesis, sorption properties and characterization

   Författare :Fredrik Björnerbäck; Niklas Hedin; Knut Irgum; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; porous materials; sorbents; microporous; CO2 capture and separation; gas adsorption; activated carbon; humins; hypercrosslinked polymers; sustainable; Materials Chemistry; materialkemi;

   Sammanfattning : The resources available to us humans, including metals, minerals, biomass, air, water, and anything else on the planet, are being used at an increasing rate. This anthropogenic use of resources both depletes the resources and has negative impacts on other resources, e.g. the biosphere. LÄS MER

5. 4. Exploring the fate of emerging contaminants during hydrothermal regeneration of carbonaceous adsorbents

   Författare :Pierre Oesterle; Stina Jansson; Jerker Fick; Ulrika Rova; Capucine Dupont; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Activated biochars; HTC; regeneration; analytical chemistry; adsorption; degradation; nontarget analysis; wastewater; circular economy; emerging contaminants; surface chemistry; Analytical Chemistry; analytisk kemi; environmental science; miljövetenskap; Pharmaceutics; galenisk farmaci; analytisk materialfysik; analytical material physics; Analytical Pharmaceutical Chemistry; analytisk farmaceutisk kemi;

   Sammanfattning : Wastewater from households and industries commonly contain emerging contaminants that are not easily removed by most wastewater treatment plants. These contaminants can be removed through adsorption onto adsorbents, such as activated carbon or biochars. LÄS MER

7. 5. Carbon Effect on Mechanical Properties in Austenitic Steels - A DFT-based Study

   Författare :Ruiwen Xie; Levente Vitos; Pär Olsson; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Teknisk materialvetenskap; Materials Science and Engineering;

   Sammanfattning : To study the effect of carbon interstitials in austenitic steels on plastic deformation mechanisms is the main goal of the present thesis. Using first-principlesmethods, the generalized stacking fault energy (GSFE) of C-alloyed γ-Fe is firstcalculated. The GSFE curve includes several prominent stacking fault energiesthat are fundamental for, e. LÄS MER
