  1. 1. Surface characterization of 2D transition metal carbides (MXenes)

    Författare :Ingemar Persson; Per Persson; Justinas Palisaitis; Johanna Rosén; Vanya Darakchieva; Vincent Mauchamp; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Research on two-dimensional (2D) materials is a rapidly growing field owing to the wide range of new interesting properties found in 2D structures that are vastly different from their three-dimensional (3D) analogues. In addition, 2D materials embodies a significant surface area that facilitates a high degree of surface reactions per unit volume or mass, that is imperative in many applications such as catalysis, energy storage, energy conversion, filtration, and single molecule sensing.

  3. 2. Phase field modeling of flaw-induced hydride precipitation kinetics in metals

    Författare :Claudio F. Nigro; Christer Persson; Malmö högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydride; phase field theory; linear elastic fracture mechanics; finite element method; phase transformation; hydrogen embrittlement; finite volume method;

    Sammanfattning : Hydrogen embrittlement can manifest itself as hydride formation in structures when in contact with hydrogen-rich environments, e.g. in space and nuclear power applications. To supplant experimentation, modeling of such phenomena is beneficial to make life prediction reduce cost and increase the understanding. LÄS MER

  4. 3. Bioinformatic methods for characterization of viral pathogens in metagenomic samples

    Författare :Fredrik Lysholm; Bengt Persson; Björn Andersson; Joseph F. Petrosino; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Virus infections impose a huge disease burden on humanity and new viruses are continuously found. As most studies of viral disease are limited to theinvestigation of known viruses, it is important to characterize all circulating viruses. LÄS MER

  5. 4. Effects of Food Supplementation and Psychosocial Stimulation on Growth and Development of Severely Malnourished Children : Intervention Studies in Bangladesh

    Författare :Baitun Nahar; Lars-Åke Persson; SM Grantham-McGregor; Tahmeed Ahmed; Kim F Michaelsen; Uppsala universitet; []
    Nyckelord :Psychosocial stimulation; food supplementation; HOME; child-rearing practices; maternal depressive symptoms; severe malnutrition; Bangladesh; International Health; Internationell hälsa;

    Sammanfattning : Early childhood malnutrition is a global public health problem with serious short- and long-term consequences. The aim of this thesis is to evaluate the effects of psychosocial stimulation (PS) with or without food supplementation (FS) on growth and development of severely malnourished children, quality of home environment, mother’s child-rearing practices and depressive symptoms.

  7. 5. Modelling precipitation and surface complexation reactions in systems with Goethite, Cu(II) and Oxyanions Containing As(V) or P(V)

    Författare :Hanna Nelson; Lars Lövgren; Staffan Sjöberg; Per Persson; M. Clara F. Magalhaes; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The aqueous solubility of oxyanion (e.g. phosphates and arsenates), and thereby their mobility, bioavailability (phosphates) and toxicity (arsenates), in soils and sediments is dependent upon their chemical speciation. In complex, multicomponent systems, equilibrium modelling can be a useful tool to predict chemical speciation. LÄS MER
