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

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

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

   Abstract : 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.

3. 12. Barrier properties of model coatings using recycled iron oxide pigment

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Nathalie Hagenfjärd; [2021]
   Keywords : Organic coatings; Iron oxide pigment; EIS; Barrier properties;

   Abstract : The aim of this study was to compare the barrier properties of organic coatings with the same polymer matrix but different types of iron oxide particles, commercial and recycled. The work was carried out for the company SSAB with the aim of investigating whether the pigment Merox ferric oxide, which is produced in-house at the company during the pickling process, can be used and replace commercial iron oxide pigment.

4. 13. The Effects of Depth and Hydrological Connectivity on Heavy Metal Loading in Riparian Zones

   University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Author : Emily Rose Williams; [2021]
   Keywords : Riparian zones; metal elements in soils; Discrete Riparian Inflow Zones DRIPs ; riparian soils; metal retention;

   Abstract : The area between a stream and land is known as a riparian zone. These zones are highly dynamic whichcarry and accumulate heavy metals and environmental contaminants. Discrete Riparian Input Zones(DRIPs) are a subset of such zones that carry concentrated amounts of water into streams at discrete points. READ MORE

5. 14. Enhancing the degradation rate of microplastics and organizing a study visit about sustainability

   University essay from KTH/Lärande

   Author : Marianne Al-Ghorabi; [2020]
   Keywords : Accommodation; assimilation; Fenton reaction; microplastics; polypropylene; polystyrene; proximal development zone; study visit; visible light photocatalysis; zinc oxide nanorods; Ackommodation; assimilation; den proximala utvecklingszonen; Fenton reaktion; fotokatalys med synligt ljus; mikroplast; polypropalen; polystyren; studiebesök; zinkoxid nanorör.;

   Abstract : Microplastics take hundreds to thousands of years to degrade in nature, and pose a threat to the environment. A photocatalytical degradation method have been developed to take advantage of solar light to degrade microplastics, however it takes several months to degrade microplastics with the process.

6. 15. A model for heterogenic catalytic conversion of carbon dioxide to methanol

   University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

   Author : Elin Johannesson; [2020]
   Keywords : Carbon dioxide; methanol; heterogeneous catalysis; zinc oxide; computational chemistry; density functional theory;

   Abstract : Since our society became industrialised, the levels of carbon dioxide in our atmosphere have been steadily rising, to the point where it in early 2020 at is 413 ppm. The high concentration is causing several troubling effects worldwide because of the increase in mean temperature that it creates, which causes longer draughts, more severe floods, and rising seawater levels to name a few.
