1. 21. Ionic transport of α-alumina below 1000°C : an in-situ impedance spectrosocpy study

   Författare :Johan Öijerholm; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; α-alumina; in-situ impedance spectroscopy; molecular dynamics; spark plasma sintering; conductivity; microstructure; Materialvetenskap; Materials science; Teknisk materialvetenskap;

   Sammanfattning : Ionic conductivity of metal oxides is critical for the function of a broad range of different components, such as electrolytes in solid oxide fuel cells and alloys designed for high temperature applications. In both cases the ionic conductivity can be studied by in situ impedance spectroscopy, which is also able to reveal information on the dielectric properties of the metal oxides, and in some cases the influence of their microstructure.

3. 22. Telomere analysis of normal and neoplastic hematopoietic cells : studies focusing on fluorescence in situ hybridization and flow cytometry

   Författare :Magnus Hultdin; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biomedicine; telomere; telomerase; fluorescence in situ hybridization; flow cytometry; flow-FISH; replication timing; chronic lymphocytic leukemia; immunoglobulin gene; prognosis; Biomedicin; Microbiology; Mikrobiologi; Medical Cell Biology; medicinsk cellbiologi;

   Sammanfattning : The telomeres are specialized structures at the end of the chromosomes composed of the repeated DNA sequence (TTAGGG)n and specific proteins bound to the DNA. The telomeres protect the chromosomes from degradation and end to end fusions. LÄS MER

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

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

   Sammanfattning : 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. 24. Microsensors for in situ electron microscopy applications

   Författare :Alexandra Nafari; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; capacitive read-out; Microsensors; In situ TEM; TEM-AFM; TEM-Nanoindenter; AFM; nanoscale characterisation; MEMS; Nanoindentation; piezoresistive read-out;

   Sammanfattning : With the ongoing miniaturisation of devices, the interest in characterising nanoscale physical properties has strongly increased. To further advance the field of nanotechnology new scientific tools are required. LÄS MER

7. 25. English Hemspråk : Language in Interaction in English Mother Tongue Instruction in Sweden

   Författare :Kirsten Stoewer; Jakob Cromdal; Nigel John Musk; Wei Li; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Mother tongue instruction; English as a heritage language; conversation analysis; classroom interaction; bilingual interaction; vocabulary teaching; language alternation; Modersmålsundervisning; engelska som modersmål; samtalsanalys; klassrumsinteraktion; tvåspråkig interaktion; ordförråd i undervisning; kodväxling;

   Sammanfattning : The thesis investigates teacher-student interaction in English mother tongue instruction (MTI), offered within mainstream education to English heritage language students in Sweden. In particular, it examines the type of language work that was in focus during the lessons and the ways teacher and students engaged in the language work in situ. LÄS MER
