2. 1. Using Molecular Dynamics Simulations to Explore Critical Property Relationships in Polymer Electrolytes : Polarity, Coordination, Ionic transport, Ion-pairing, and Ion-ion Correlations

   Author : Harish Gudla; Daniel Brandell; Chao Zhang; Andreas Heuer; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Solid polymer electrolytes; molecular dynamics simulations; solvent polarity; ion-pairing; ion coordination; ion transport mechanisms; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

   Abstract : While ion transport in solid polymer electrolytes (SPEs) has been explored for decades, there still remains controversies about its fundamental properties, often correlated with gaps between experimental and computational studies. Using molecular dynamics simulations to understand the complex transport mechanisms and also to fill these gaps is the main goal of this thesis. READ MORE

4. 2. Dynamic Structure Discovery and Ion Transport in Liquid Battery Electrolytes

   Author : Rasmus Andersson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ion transport mechanisms; electrolytes; dynamic structure discovery; lithium-ion batteries; statistical physics;

   Abstract : The lithium-ion battery (LIB), the realisation of which earned the Nobel Prize in Chemistry 2019, has since its 1991 commercialisation become the dominant energy storage technology first for cell phones and other mobile electronics, then for power tools and other domestic appliances, and currently for electric cars and other vehicles. However, many applications would still benefit from higher power and energy densities, longer life-lengths and safer batteries. READ MORE

5. 3. Ion transport in exocrine glands with reference to cystic fibrosis

   Author : Ailing Zhang; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; ion transport; cystic fibrosis; submandibular gland; airway submucosal gland; X-ray microanalysis; cytosolic Ca2 concentration; immunocytochemistry; Cellbiologi; Cell biology; Cellbiologi; Human Anatomy; anatomi;

   Abstract : Aspects of ion transport in rat submandibular gland acinar cells at the subcellular level, and the regulation of chloride secretion and calcium mobilization in cultured pig tracheal gland acinar cells were studied with reference to the disease cystic fibrosis.In adult rat submandibular gland acinar cells, both cholinergic and α-adrenergic stimulation induced efflux of K+ and of C1-, but the response was generally less with α-adrenergic stimulation.

   Abstract : Electrifying passenger transport is a key strategy in combating global warming, with Li-ion batteries (LIBs) being the current go-to technology. Despite LIB’s satisfactory performance and carbon-neutral operation, lifetime and safety are still public concerns. READ MORE

7. 5. Ion Transport in Glial and Neuroblastoma Cells

   Author : Sonya K. A. Juthberg; Linköpings universitet; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : The aim of this thesis has been to increase our understanding of the ion channel function and the ion transport mechanisms in glial cells. The analysis has also covered Na channel function in human neuroblastoma cells in order to get a basis for similar studies of glial cells In paper I isotopes 42K and 201 Tl were used to compare the K+ transport properties in cell lines from human malignant gliomas (U-251MG and Tp-378MG), carcinomas, and brain metastasis.
