  1. 1. Metal homeostasis as critical determinant for cellular fitness

    Författare :Jutta Diessl; Sabrina Büttner; Rajini Rao; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; metal homeostasis; manganese toxicity; coenzyme Q synthesis; mitochondrial respiration; calcineurin signaling; Pmr1; SPCA1; calcium; survival; caloric restriction; Parkinson’s disease models; proteotoxicity; Pep4; cathepsin D; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : Metals play a crucial role in cellular biology. Bulk and trace metals such as calcium and manganese regulate a plethora of cellular processes ranging from signaling and oxidative stress to proteostasis and energy metabolism. LÄS MER

  3. 2. De samiska metalldepåerna år 1000-1350 : i ljuset av fyndet från Mörtträsket, Lappland

    Författare :Inger Zachrisson; Umeå universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; Saami; metal deposits; sacrificial sites; tradesman’s stock; thief’s hiding-place; pewter pendants; ring-shaped brooches; tin; lead; pewter casting; ornamentation; silver hoards; culture fixation; Offerfynd; Samiska kultplatser-- Sverige -- Lappland; Mörtträsket; Gråträsk;

    Sammanfattning : The thesis arises out of a new find from Mörtträsket, Lapland, which can be compared with the eleven so called "Finds from Lapp Places of Sacrifice" from North Scandinavia, dated to c. 1000-1350. The Mörtträsket find is characterized by newly made objects and is interpreted as a tradesman's stock. LÄS MER

  4. 3. The life and death of perovskites : Interfacial function and degradation of lead halide perovskites studied by photoelectron spectroscopy

    Författare :Sebastian Svanström; Ute B Cappel; Håkan Rensmo; Erik Johansson; Selina Olthof; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; lead halide perovskite solar cells; interfacial degradation; heterojunction interfaces; photoelectron spectroscopy; operando; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Sammanfattning : Lead halide perovskite solar cells are a promising new technology which could soon see widespread commercial application but is partly held back by poor long-term stability. In this thesis, photoelectron spectroscopy (PES) is used to study the dynamical processes at the surface or interfaces of lead halide perovskite materials. LÄS MER

  5. 4. Molecular mechanisms of metal toxicity in neuronal cells

    Författare :Annamaria Rossi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Modification of signal transduction by toxic agents can affect cell metabolism and physiological activity, impair cell capacity to adequately respond to hormones and growth stimuli and consequently compromise cell survival. This thesis describes studies on the interactions between toxic metals, at concentrations comparable to environmental exposure, and Ca2+ signalling in neuronal cells. LÄS MER

  7. 5. Life and Death of Mixed Metal Halide Perovskites : Mechanism and Consequences of Light Induced Halide Segregation in MAPb(I,Br)3

    Författare :Klara Suchan; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; phase segregation; X-ray diffraction; perovskite; solar cells; photoluminescence;

    Sammanfattning : Metal halide perovskites have attracted immense scientific interest due to their outstanding optoelectronic properties over a widebandgap range. Applications cover a wide range of optoelectronic devices from solar cells, LEDs and lasers to X-ray detectors. LÄS MER
