1. 1. Failure mechanisms in APS and SPS thermal barrier coatings during cyclic oxidation and hot corrosion

   Författare :Krisha Praveen Jonnalagadda; Ru Lin Peng; Xin-Hai Li; Robert Eriksson; Shrikant Joshi; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Thermal Barrier Coatings (TBCs) are advanced material systems that are being used in the hot sections of gas turbines such as combustor, turbine blades, and vanes. The top ceramic coating in TBCs provides insulation against the hot gases and the intermediate metallic bond coat provides oxidation and corrosion resistance to the underlying turbine components.

3. 2. Thermal Barrier Coatings : Failure Mechanisms and Life Prediction

   Författare :Krishna Praveen Jonnalagadda; Ru Lin Peng; Xin-Hai Li; Robert Eriksson; Nicholls John; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Thermal barrier coatings (TBCs) use in the hot sections of gas turbine engine enables them to run at higher temperatures, and as a consequence, achieve higher thermal efficiency. For full operational exploitation of TBCs, understanding their failure and knowing the service life is essential. LÄS MER

4. 3. Wireless video sensor network and its applications in digital zoo

   Författare :Johannes Karlsson; Haibo Li; Jerry Eriksson; Oliver Wu Dapeng; Umeå universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless Sensor Networks; Wireless ad-hoc Networks; Digital Zoo; Video Compression; Real-Time Video Communication; Object Tracking; Sensor Fusion; Other electrical engineering; electronics and photonics; Övrig elektroteknik; elektronik och fotonik; signalbehandling; Signal Processing;

   Sammanfattning : Most computing and communicating devices have been personal computers that were connected to Internet through a fixed network connection. It is believed that future communication devices will not be of this type. Instead the intelligence and communication capability will move into various objects that surround us. LÄS MER

5. 4. Cation Conduction and Coordination in Carbonyl-Containing Compounds : Li+ Transport in Alternative Polymer Electrolyte Host Materials

   Författare :Therese Eriksson; Daniel Brandell; Jonas Mindemark; Claudio Gerbaldi; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Solid polymer electrolytes; Lithium ion batteries; Ion transport; Polyester; Polycarbonate; Polyketone; Ion coordination; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

   Sammanfattning : The field of solid polymer electrolytes (SPEs) used to create safer lithium-ion batteries has been dominated by polyethylene oxide (PEO) since the discovery of its ion-conducting properties in the 1970s. In this thesis, as an alternative, the ion coordination and conduction properties of SPEs based on polyketones, polyesters and polycarbonates are investigated. LÄS MER

7. 5. LiMn2O4 as a Li-ion Battery Cathode. From Bulk to Electrolyte Interface

   Författare :Tom Eriksson; Michael M. Thackeray; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; cathode materials; lithium manganese oxide; interface; surface layer; electrode kinetics; Kemi; Chemistry; Kemi; Inorganic Chemistry; oorganisk kemi;

   Sammanfattning : LiMn2O4 is ideal as a high-capacity Li-ion battery cathode material by virtue of its low toxicity, low cost, and the high natural abundance of Mn. Surface related reactions and bulk kinetics have been the major focus of this work. LÄS MER
