1. 1. Investigating Surface Oxide Composition and Formation on Metallic Vibenite® Alloys

   University essay from Uppsala universitet/Institutionen för materialvetenskap

   Author : Emil Monie; Nils Säfström; Yiping Deng; Axel Möllerberg; [2022]
   Keywords : Vibenite; oxide; oxide growth; surface refinement; surface smoothing; alloys; additive manufacturing; controlled oxides;

   Abstract : Oxide formation on metallic surfaces is a common phenomenon which occursnaturally or intently. Depending on the metallic oxide, they can be viewed as either nuisances or conveniences depending on the effects of the oxide. READ MORE

3. 2. Characterisation of additively manufactured Inconel 718 alloy by using electrolytic extraction

   University essay from KTH/Materialvetenskap

   Author : Leyla Koort; Viktoria Sutorius Trollbäck; [2021]
   Keywords : ;

   Abstract : The formation of non-metallic inclusions (NMIs) are common in all steel grades and it is not possible  as  of  today  to  be able  to  remove  all  of them.  The  inclusions  are  categorised  into endogenous (oxides, nitrides, sulfides, carbides, and phosphides), and exogenous (entrapment of  nonmetals:  slag, mold).

4. 3. Chemical Stabilization of Arsenic in Contaminated Soil under Low Redox Conditions

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Eva Smedborn Pausson; [2019]
   Keywords : ;

   Abstract : Remediation techniques for arsenic contaminated soil have previously focused mostly on the surface soil layers where aerobic conditions are prevalent. In this master thesis, chemical stabilization by adding zero-valent iron (Fe(0)) and calcium oxide (CaO) to an arsenic-contaminated soil under low redox conditions have been studied through up-flow percolation tests.

5. 4. Manipulation of thin metal film growth on weakly-interacting substrates using gaseous surfactants

   University essay from Linköpings universitet/Nanodesign

   Author : Martin Konpan; [2019]
   Keywords : Surface physics; material science;

   Abstract : Thin films are structures with thicknesses ranging from the atomic scale to the mesoscale that are used to alter the properties of a surface and/or serve as functional layers in devices. Thin metal films deposited from the vapor phase on weakly-interacting substrates, including oxides (TiO2, ZnO, SiO2 etc. READ MORE

6. 5. InAs and high-k oxides, a scanning tunnelling study of their interfaces

   University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

   Author : Mattias Åstrand; [2018]
   Keywords : Semiconductor; High-k; Atomic layer deposition; Scanning tunnelling microscopy; Scanning tunnelling spectroscopy; Physics and Astronomy;

   Abstract : In order for semiconductor materials to be suitable for implementation in new and progressive devices they have to be of better electronic characteristics than currently used materials, and maintain these once treated and put into action. It is important to verify that bulk characteristics are not hindered at the surface when a given semiconductor is put in contact with another material due to necessity. READ MORE
