  2. 1. Single-Electron Tunneling Spectroscopy in Magnetic Nanoparticles and Molecular Magnets

    Author : Lukasz Michalak; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; master equation; magnetic nanoparticles; spin accumulation; molecular magnets; TMR; tunneling magnetoresistance; F-SET; ferromagnetic single-electron transistor; single-electron tunneling; nanomagnetism; spintronics; Coulomb blockade;

    Abstract : This thesis deals with single-electron tunneling in transistor-like devices in which the central electrode is either a metal nanoparticle (possibly ferromagnetic) or a molecular magnet. The investigated systems split into two different categories, depending on the size of the central island. READ MORE

  4. 2. Bioremediation of Toxic Metals for Protecting Human Health and the Ecosystem

    Author : Aminur Rahman; Abul Mandal; Jana Jass; Björn Olsson; Pawel Kaszycki; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Heavy Metals; Pollution; Accumulation; Remediation; Human Health; Bacteria; Genome Sequencing; de novo Assembly; Gene Prediction; Biology; Biologi; Bioteknik;

    Abstract : Heavy metal pollutants, discharged into the ecosystem as waste by anthropogenic activities, contaminate drinking water for millions of people and animals in many regions of the world. Long term exposure to these metals, leads to several lethal diseases like cancer, keratosis, gangrene, diabetes, cardio- vascular disorders, etc. READ MORE

  5. 3. Accumulation and Cellular Clearance of IAPP and Proteotoxicity of ATTR in Drosophila Models

    Author : Xiaohong Gu; Gunilla Westermark; Anders Olofsson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; amyloid; IAPP; ATTR; ATTR amyloidosis; crystalline structure; aggrephagy; Drosophila melanogaster; Gal4-UAS; electron tomography; DAMS; SOHA; Medical Cell Biology; Medicinsk cellbiologi;

    Abstract : Proteins’ functions are dependent on their three-dimensional (3D) structure. Under certain circumstances, proteins misfold and form aggregates, sometimes leading to amyloidosis. Islet amyloid polypeptide (IAPP) builds up amyloid in the pancreatic islet of patients with type 2 diabetes (T2D).

  6. 4. Membrane morphology and homeostasis: An electron microscopy approach

    Author : Dimitra Panagaki; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nuclear envelope bud; AdipoR2; membrane homeostasis;

    Abstract : Biological membranes allow life as we know it to exist. Primarily assembled from lipids and proteins, their morphology and function can greatly vary between species or even within the same cell. They create physical boundaries, separating different cells from each other and forming functional compartments within the cells. READ MORE

  7. 5. Synthesis of Biomimetic Systems for Proton and Electron Transfer Reactions in the Ground and Excited State

    Author : Giovanny A. Parada; Sascha Ott; Ana Moore; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Solar energy conversion; artificial photosynthesis; hydrogen bonds; excited state intramolecular proton transfer; tautomerization; proton-coupled electron transfer; photosensitizer; ruthenium complex.; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

    Abstract : A detailed understanding of natural photosynthesis provides inspiration for the development of sustainable and renewable energy sources, i.e. a technology that is capable of converting solar energy directly into chemical fuels. This concept is called artificial photosynthesis. READ MORE
