  2. 1. The HiPIMS Process

    Author : Daniel Lundin; Ulf Helmersson; Nils Brenning; Jeffrey A. Hopwood; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The work presented in this thesis involves experimental and theoretical studies related to a thin film deposition technique called high power impulse magnetron sputtering (HiPIMS), and more specifically the plasma properties and how they influence the coating. HiPIMS is an ionized physical vapor deposition technique based on conventional direct current magnetron sputtering (DCMS). READ MORE

  5. 3. The evolution of ribonucleotide reductases

    Author : Daniel Lundin; Anthony Poole; Britt-Marie Sjöberg; Christos Ouzounis; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Evolution; ribonucleotide reductase; horizontal gene transfer; phylogeny; protein classification; Molecular biology; Molekylärbiologi; Molecular Biology; molekylärbiologi;

    Abstract : Ribonucleotide reductase (RNR) catalyses the transformation of RNA building blocks, ribonucleotides, to DNA building blocks, deoxyribonucleotides. This is the only extant reaction pathway for de novo synthesis of DNA building blocks and the enzyme is thus necessary for life. RNR is found in all but a few organisms. READ MORE

  6. 4. Social below ground : Life-history and gut microbiome of Damaraland mole-rats

    Author : Hanna Bensch; Markus Zöttl; Jonas Waldenström; Daniel Lundin; Sarah Knowles; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Evolutionary Biology; Evolutionsbiologi; Ecology; Ekologi;

    Abstract : Studying the consequences of variation in individual life-histories is vital for our understanding of the evolution of animal societies. In this thesis, I study the ecology and consequences of group living on growth, survival, reproduction, and the gut microbiome of the Damaraland mole-rat (Fukomys damarensis), a subterranean cooperatively breeding mammal.

  7. 5. Area Selective Chemical Vapor Deposition of Metallic Films using Plasma Electrons as Reducing Agents

    Author : Hama Nadhom; Henrik Pedersen; Daniel Lundin; Kostas Sarakinos; Erwin Kessels; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Metallic films are used to improve optical, chemical, mechanical, magnetic, and electrical properties and are therefore of high importance in many applications, from electronics and catalysis, environmental protection and health, to wearable and flexible electronic materials. Many of these applications, however, require that the metal films are deposited uniformly on topographically complex surfaces and structures. READ MORE
