  1. 21. Development of Metal–Organic Frameworks for Catalysis : Designing Functional and Porous Crystals

    Författare :Fabian Carson; Xiaodong Zou; Jeffrey R. Long; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Metal–organic frameworks; heterogeneous catalysis; nanoparticles; metallolinkers; postsynthetic modification; postsynthetic exchange; Inorganic Chemistry; oorganisk kemi;

    Sammanfattning : Metal–organic frameworks, or MOFs, have emerged as a new class of porous materials made by linking metal and organic units. The easy preparation, structural and functional tunability, ultrahigh porosity, and enormous surface areas of MOFs have led to them becoming one of the fastest growing fields in chemistry. LÄS MER

  2. 22. Fatigue in patients with chronic heart failure. Patient experience and consequences of fatigue in daily life

    Författare :Kristin Falk; Göteborgs universitet; []
    Nyckelord :fatigue; chronic heart failure; uncertainty; sense of coherence; anxiety; depression; symptom distress; hemoglobin; functional status;

    Sammanfattning : Although fatigue is a prevalent and distressing symptom in patients with chronic heart failure (CHF), it is an underestimated problem in the care of patients, and consequently, insufficiently investigated. The primary aim of this thesis was, therefore, to advance the knowledge from the patients? perspective by describing characteristics of the fatigue experience and its consequences in daily life in patients with CHF.

  3. 23. Cold Acclimation : Dissecting the plant low temperature signaling pathway using functional genomics

    Författare :Catherine Benedict; Vaughan Hurry; Matsuo Uemura; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cold acclimation; functional genomics; microarray; Populus tremula; Arabidopsis thaliana; gene voting; regulon; enhancer-blocking; Plant physiology; Växtfysiologi;

    Sammanfattning : The physiological process of cold acclimation protects plants native to the temperate regions of the world from the deleterious effects of low and freezing temperatures. This is achieved by a series of transcriptional, regulatory, and metabolic changes that enable continued growth and survival. Within minutes of exposure to temperatures below ca. LÄS MER

  4. 24. Functional Materials for Perovskite Solar Cells

    Författare :Wei Zhang; Lars Kloo; Neil Robertson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; perovskite solar cell; photovoltaic device; lead-free light absorbers; hole-transport materials; coordination complexes; p-type dopants; organic salts; surface passivation.; Kemi; Chemistry;

    Sammanfattning : Energy plays a significant role in our daily lives, but most energy provided by fossil fuels causes serious environmental problems including air pollution, global warming, and ecological damage. In addition, it has been estimated that all of our fossil fuels will run out in 2088 and thus it is highly important to study and apply renewable energy sources. LÄS MER

  5. 25. Gastrointestinal disturbances in hereditary transthyretin amyloidosis

    Författare :Jonas Wixner; Ole B Suhr; Intissar Anan; Pontus Karling; Anders Rönnblom; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Autonomic Nervous Systems; Cajal Interstitial Cells; Enteric Nervous System; Familial Amyloid Polyneuropathy; Functional Gastrointestinal Disorders; Gastric Emptying; Liver Transplantation; Nutrition Status; Transthyretin Amyloidosis; medicin; Medicine;

    Sammanfattning : BackgroundTransthyretin amyloid (ATTR) amyloidosis is a systemic disorder caused by amyloid deposits formed by misfolded transthyretin (TTR) monomers. Two main forms exist – wild-type and hereditary ATTR amyloidosis, the latter associated with TTR gene mutations. LÄS MER
