  2. 1. Nanoscale electron tomography and compositional analysis of Aerotaxy nanowires

    Author : Axel Persson; -lup-obsolete; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Transmission Electron Microscopy; Electron tomography; Nanowires; Aerotaxy;

    Abstract : One common goal of sample analysis is to provide structural, compositional, or functional data in order to improve production parameters. One instrument specialized in such structural and compositional analysis with a high spatial resolution is the transmission electron microscope (TEM). READ MORE

  4. 2. Transmission Electron Tomography and In-situ Analysis of Nanowires

    Author : Axel Persson; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Transmission electron microscopy TEM ; Electron tomography; Nanowires NWs ; Aerotaxy; In-situ;

    Abstract : As semiconducting nanowires have promising applications for materials science, nanoelectronics and photovoltaic devices, absolute control of their structure, morphology and composition is a prerequisite for their functionality. Nanowires, grown through the vapor-liquid-solid (VLS) method, exhibit a complex relationship between their liquid seed particle and what properties, such as the aforementioned ones, the wire adopts in the end.

  5. 3. Incidental Gallbladder Cancer : Incidence, predictors, management and outcome in a Swedish population

    Author : Linda Lundgren; Per A Sandström; Axel Ros; Gunnar Persson; Oliver Gimm; Magnus Nilsson; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Background: Cholecystectomy is a common surgical procedure and incidental gallbladder cancer is a rare and unexpected finding at a cholecystectomy performed upon benign indications. Whether to perform routine or selective histopathology of the gallbladder specimen is still a subject for discussion. READ MORE

  6. 4. Interaction between Calcium, Calciotropic Hormones and the Gastrin-ECL-cell Axis

    Author : Rebecca Gagnemo Persson; Hälsofrämjande komplexa interventioner; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pharmacognosy; Pharmacological sciences; rat; chicken; parathyroid gland; stomach; vitamin D; PTH; CT; calciotropic hormones; Gastrin; calcium; ECL cell; pharmacy; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi; Histology; cytochemistry; histochemistry; tissue culture; Histologi; cytokemi; histokemi; vävnadskultur;

    Abstract : Calcium homeostasis involves mainly the interaction of PTH, vitamin D and CT. The stomach may be important for calcium homeostasis. Gastric acid is thought to mobilize calcium from the diet, thereby facilitating the absorption of calcium in the small intestines. READ MORE
