2. 1. Refining of hydrochars/ hydrothermally carbonized biomass into activated carbons and their applications

   Author : Wenming Hao; Niklas Hedin; Robert Mokaya; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hydrothermally carbonized biomass; activated carbon; full factorial design; activated carbon disc; nanoparticles; iron oxide; CO2 separation; methylene blue; adsorption; Materials Chemistry; materialkemi;

   Abstract : 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. READ MORE

4. 2. Nanomaterials for membranes and catalysts

   Author : Stylianos Nassos; Sven Järås; Carina Lagergren; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanotechnology; microemulsion; nanoparticles; hydrogen production; CO2 capture; selective catalytic oxidation of ammonia; activity; gasified biomass; Chemical engineering; Kemiteknik;

   Abstract : Nanotechnology is a relatively new research topic that attracts increasing interest from scientists and engineers all over the world, due to its novel applications. The use of nanomaterials has extended to a broad range of applications, for example chemical synthesis, microporous media synthesis and catalytic combustion, contributing to achievement of improved or promising results.

6. 4. Potential of Organosolv Lignin Nanoparticles as a Sustainable Flotation Reagent : Towards a Low-Carbon Footprint Mining Industry

   Author : Katerina Hruzova; Ulrika Rova; Saija Luukkanen; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Organosolv lignin particles; Nanoparticles; Flotation reagent; Copper recovery; Biokemisk processteknik; Biochemical Process Engineering;

   Abstract : The green transition is driving a steep increase in the demand for minerals, which has put the focus on more responsible and sustainable mining practices as there is a growing pressure on mining operations to minimise their environmental footprint, mitigate risks in neighbouring communities, and decrease the consumption of natural resources. In 2022, mineral froth flotation was used to recover 18 million tonnes of copper from copper ore, accounting for 80% of total copper mine output. READ MORE

7. 5. Experimental Determination of the Deposition of Aerosol Particles in the Human Respiratory Tract

   Author : Jakob Löndahl; Kärnfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; nanoparticles; deposition; respiratory tract; health; air pollution; aerosol particle; ultrafine particles; lung; Fysicumarkivet A:000;

   Abstract : BACKGROUND: Aerosol particles have, since the antiquity, been linked to adverse effects on human health. It is estimated that the particles in urban air pollution cause at least 100,000 deaths in Europe each year, whereof 5,000 in Sweden. READ MORE
