1. 21. Development of alkaline earth metal-based, metal-organic frameworks for greenhouse gas sorption

   University essay from Uppsala universitet/Institutionen för materialvetenskap

   Author : Ali Maghsoodpoor; [2022]
   Keywords : Metal-organic Framework; gas sorption;

   Abstract : Metal-organic frameworks (MOFs) constructed from metal atoms connected by organic linkers have received extensive attention for greenhouse gas separation in the past decades. Moreover, their large surface area makes them a promising candidate as adsorbents for gas sorption. READ MORE

3. 22. Arctica Islandica – Annually Banded Mollusc Offers High Temporal Resolution Record Into End Of North Sea Little Ice Age

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Eilidh Towers; [2022]
   Keywords : sclerochronology; Arctica islandica; palaeoenvironments; Little Ice Age; radiocarbon reservoir effect;

   Abstract : Sclerochronology affirms the well-established fact that banded growth increments in marine molluscs accurately record oscillations in climate and environment for the past millennia or more. This study considers how such records can enhance understanding of environmental shifts across the 18th to 20th centuries. READ MORE

4. 23. Investigation of stability in high salt polymer electrolytes for sodium batteries

   University essay from Uppsala universitet/Strukturkemi

   Author : Fengnan Yuan; [2022]
   Keywords : ;

   Abstract : Poly(trimethylene carbonate)–sodium bis(fluorosulfonyl)imide system shows a promising performance as polymer-in-salt electrolytes. The polymer electrolytes with salts concentration from 62% to 71% were tested through DSC, FTIR, EIS and constant current cycling. The solubility of the salts varies in different salts in PTMC.

5. 24. Polymerized Tubular Silicates in Lower Cambrian Carbonates – Biology or Chemistry?

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Scott Green; [2022]
   Keywords : biosignature; tubular structures; Lower Cambrian; silica precipitation; bifurcating; biosignatur; rörstrukturer; Kambrium Serie 3; kiseldioxid utfällning; förgrening;

   Abstract : Shallow marine environments from the Lower Cambrian period were very different to shallow marine environments of today. Tubes of what was thought to be silica recovered from a partly dolomitized carbonate sample collected form a site near Indian Springs, Nevada could help further understand the chemistry and characteristics of such environments.

6. 25. Petrography and Mineral Chemistry of the Sälskär Breccia (Alnö Alkaline Complex, Central Sweden)

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Vincent Gustafsson; [2022]
   Keywords : Alnö alkaline complex; diatreme; melilitite; pelletal lapilli; volcanic breccia; Alnö alkalina område; diatrem; melilitit; pelletal lapilli; vulkanisk breccia;

   Abstract : Primitive magmas can provide important details about the mantle from which they are derived. In this thesis, petrographic observations and new mineral chemistry analyses of the Sälskär breccia from the Alnö alkaline complex, central Sweden, are reported. READ MORE
