1. Petrography and Mineral Chemistry of the Sälskär Breccia (Alnö Alkaline Complex, Central Sweden)
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : 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

2. Lejarfjället Garnet(?) Peridotite – Origin and Petrological Characterization of Symplectitic Aggregates in Ultramafic Rocks
University essay from Uppsala universitet/Mineralogi, petrologi och tektonikAbstract : Ultramafic rocks are abundant in the Earth’s mantle but rare on the surface. Since no in-situ samples from the mantle can be collected, mantle rocks provide knowledge of mechanisms operating in the mantle and large-scale processes that brought them up to the surface.

3. The “ultramafic” Intrusion’s within the peridotite from Härbergsdalen : Petrological characterization of infiltration record within the lithospheric mantle
University essay from Uppsala universitet/Mineralogi, petrologi och tektonikAbstract : The mantle constitutes ~80% of Earths volume, however, due to its location deep beneath Earth’s surface the mantle is inaccessible to study in situ. Despite this, we still have information about its composition thanks to seismic studies which haven proven the mantle to be in generally homogenous and dominated by a rock called peridotite.

4. Study on the Electronic Band Structure of the Spinel Superconductor LiTi2O4
University essay from KTH/Tillämpad fysikAbstract : This master’s thesis focuses on investigating the electronic properties of the superconducting spinel compound LiTi2O4 by means of computational and experimental effort. The title compound has been extensively studied in the past years, being the only known superconducting spinel oxide with relatively high Tc = 11.5 K. READ MORE

5. Nitrogen Without Oxygen : The effect of ferroalloys added after vacuum treatment on cleanliness of nitrogen-alloyed tool steel
University essay from KTH/MaterialvetenskapAbstract : Nitrogen-alloyed tool steel is made at Uddeholms AB by adding high-nitrogen ferroalloy after vacuum degassing where introduced impurities are hard to remove. In this thesis two types of high-nitrogen ferrochromium are compared, a solid version and a powder cored wire. READ MORE
