2. 1. Microstructure and oxidation behavior of High Velocity Oxy-Fuel spray deposited Ti2AlC coatings

   Author : Marie Sonestedt; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; coatings; High Velocity Oxy-Fuel HVOF ; Ti2AlC; oxidation; microstructure; SEM; TEM;

   Abstract : Ti2AlC is one of the ternary carbides in the MAX phase group of materials. This group of materials have a unique combination of ceramic and metallic properties, such as machinability, high thermal conductivity, low density and oxidation resistance. READ MORE

4. 2. Surface modification of inorganic materials with graphene oxide : From solution to high-temperature synthesis

   Author : Simon Tidén; Ulf Jansson; Mamoun Taher; Erik Lewin; Lars Nyborg; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Graphene; Graphene oxide; Coatings; Additive Manufacturing; Laser Powder Bed Fusion; Reactive Hot Pressing; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

   Abstract : The use of graphene as an additive in materials is often challenging due to the agglomeration of the two-dimensional graphene sheets. An alternative additive is graphene oxide (GO), an oxidized form of graphene, which is easily dispersed in water. READ MORE

5. 3. Thick and Thin Ti2AlC Coatings

   Author : Jenny Frodelius; Lars Hultman; Per Eklund; Hans Högberg; Lars Nyborg; Linköpings universitet; []
   Keywords : NATURAL SCIENCES; NATURVETENSKAP;

   Abstract : This Thesis explores the deposition techniques of magnetron sputtering and high velocity oxy-fuel (HVOF) spraying for Ti2AlC as a promising high-temperature material. Magnetron sputtering aims at producing thin (≤1 μm) Ti2AlC films of high crystal quality for use as a model system in understanding the material’s basic properties. READ MORE

6. 4. Design of Thermal Barrier Coatings

   Author : Nicholas Curry; Nicolaie Markocsan; Per Nylén; Matthias Oechsner; Högskolan Väst; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Gas Turbine; Aero Turbine; Thermal Barrier Coating; Atmospheric Plasma Spraying; Suspension Plasma Spraying; Thermal Conductivity; Thermo-cyclic fatigue; Thermal Shock; Manufacturing and materials engineering; Produktions- och materialteknik;

   Abstract : Thermal barrier coatings (TBC’s) are used to provide both thermal insulation and oxidation protection to high temperature components within gas turbines. The development of turbines for power generation and aviation has led to designs where the operation conditions exceed the upper limits of most conventional engineering materials. READ MORE

7. 5. Processing of berries – Effects on functionality, stability and bioactivity of anthocyanins

   Author : Gabriel Barbosa; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; berries; powder; hot air and microwave drying; osmotic dehydration; press cake; edible coating; anthocyanins; gastrointestinal in vitro digestion; polyphenols; pulsed electric field; oxidative stress; yeast;

   Abstract : Berries are rich natural sources of anthocyanins, water-soluble pigments in plants that have been linked to beneficial effects against chronic diseases, such as cardiovascular diseases, type 2 diabetes and neurodegenerative diseases. However, anthocyanins as well as other polyphenolic compounds are often sensitive to degradation during processing, storage and digestion. READ MORE
