1. 16. Development and Use of Optical Sensors in Modern Analytical Chemistry

   Författare :Aron Hakonen; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optical sensors; Optodes; Imaging sensors; Fluorescence; pH; Ammonium; Sensing; Nanoparticle enhancement; Plasmonics;

   Sammanfattning : A successful long-term high resolution imaging experiment in marine sediments was performed (17 days within the sample; Paper I). The time correlated calibration procedure was evolved to include parametric sigmoidal and logarithmic functions to provide three of the best performing (optical) pH sensors available up to date (Papers II, III and IV), precision of these sensors were in the 0.

3. 17. Automating STED microscopy for functional and structural live-cell imaging

   Författare :Jonatan Alvelid; Ilaria Testa; Eggeling Christian; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; STED; microscopy; nanoscopy; super-resolution microscopy; automation; image analysis; fluorophores; Biologisk fysik; Biological Physics;

   Sammanfattning : Optical microscopy imaging methods are today invaluable tools for studies in life sciences as they allow visualization of biological systems, tissues, cells, and sub-cellular compartments from millimetres down to nanometres. The invention and development of nanoscopy in the past 20 years has pushed fluorescence microscopy down to the nanoscale, reaching beyond the natural diffraction limit of light that does not allow focusing of visible light below sizes of around 200 nm, and into the realm of what was previously only thought possible with electron microscopy.

4. 18. Rational design of nanoparticles for biomedical imaging and photovoltaic applications

   Författare :Haiyan Qin; Hans Ågren; Alexander Dmitriev; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Theoretical chemistry; Teoretisk kemi;

   Sammanfattning : This thesis aims to rationally design nanoparticles and promote their applications in biomedical imaging and photovoltaic cells. Quantum dots (QDs) are promising fluorescent probes for biomedical imaging. LÄS MER

5. 19. Development of a Methodology for Dynamic Testing of Rock Support : Field Tests and Numerical Analysis

   Författare :Shahin Shirzadegan; Erling Nordlund; Ping Zhang; Charlie Chunlin Li; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

   Sammanfattning : The increasing mining depth in the Luossavaara-Kiirunavaara Aktiebolag (LKAB) mine located in the northern part of Sweden leads to higher stress magnitudes, resulting in increased seismic activity and more seismically-induced damage. The effectiveness of various ground support systems under dynamic loading conditions has therefore become of prime interest to LKAB for successful and safe mining at deep levels. LÄS MER

7. 20. Characterization of electrical properties in 4H-SiC by imaging techniques

   Författare :John Österman; Anders Hallén; Vito Raineri; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Elektroteknik; elektronik och fotonik; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

   Sammanfattning : 4H-SiC has physical properties supremely suited for a variety of high power, high frequency and high temperature electronic device applications. To fully take advantage of the material's potential, several problems remain to be solved. LÄS MER
