1. 11. 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. 12. High-grade spondylolisthesis in young patients : Long-term results of in situ fusion

   Författare :Anders Joelson; Per Wretenberg; Karin Frennered; Hans Tropp; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adjacent segment disk degeneration; Fusion in situ; Health-related quality of life; Sagittal balance; Self-image; Spondylolisthesis;

   Sammanfattning : The purpose of this long-term follow-up of 38 of 40 consecutive patients was to evaluate the results of uninstrumented in situ fusion for high-grade isthmic spondylolisthesis three decades after surgery. The mean age at surgery was 14 (range 9-24) years. LÄS MER

4. 13. 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. 14. 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
