1. 21. Optical Guiding and Feedback Structures in GaN-Based Vertical-Cavity Surface-Emitting Lasers

   Författare :Seyed Ehsan Hashemi; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The Vertical-Cavity Surface-Emitting Laser (VCSEL) made from GaAs-based materials is an established infrared light source, and is produced in large volumes for short-distance optical links, computer mice, and thermal processing systems. A wide range of applications, such as high-resolution printing, general lighting, and biomedical diagnosis and treatment could benefit from using a VCSEL with blue or ultraviolet emission. LÄS MER

3. 22. Luminescent textiles using biobased products : A bioinspired approach

   Författare :Sweta Iyer; Högskolan i Borås; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; bioinspired; biobased; bioluminescent; photoluminescent; textile; luminous bacteria; enzymes; immobilization; plasma; riboflavin; flavin mononucleotide; sustainable; digital printing; functionalization; Textil och mode generell ; Textiles and Fashion General ;

   Sammanfattning : Nature has designed a few biobased molecules that are responsible for bioluminescence and photoluminescence in some living species. In this thesis, the potential use of luminescence phenomena existing in nature toward the attainment of luminescent textiles was explored. LÄS MER

4. 23. Nanostructures of Graphite and Amorphous Carbon - Fabrication and Properties

   Författare :Hans Fredriksson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; optical resonance; Raman-spectrum; carbon; optical spectrum; HOPG; GC amorphous carbon; oxidation; Nanofabrication;

   Sammanfattning : Nanoscience is a well-established research area, which concerns properties and fabrication of objects with typical dimensions on the 1-100 nanometer length scale. A central issue has been the development of techniques for fabrication and characterization of nanometer sized objects, which have contributed considerably to progress in both practical applications and fundamental research.

5. 24. Träffad av blixten eller långsam kvävning : genuskodade uttryck för depression i en primärvårdskontext

   Författare :Ulla EB Danielsson; Eva E Johansson; Carita Bengs; Eva Samuelsson; Bengt Mattsson; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; depression; gender; class; shame; adolescents; media; primary health care; consultation; grounded theory; qualitative research; Family medicine; Allmänmedicin; Family Medicine; allmänmedicin;

   Sammanfattning : Depression is a common mental health problem in primary health care. One third of the Swedish population is expected to experience depression at some point in their lives. The understanding of depression has expanded, both from a lay and primary health care perspective. LÄS MER

7. 25. Elastic Neutron Scattering at 96 MeV

   Författare :Joakim Klug; Jan Blomgren; Arjan Plompen; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; neutron; detection; CsI; elastic scattering; differential cross section; optical potential; kerma; Kärnfysik; Nuclear physics; Kärnfysik; Applied Nuclear Physics; Tillämpad kärnfysik;

   Sammanfattning : A facility for studies of elastic neutron scattering in the 50–130 MeV range has been developed. In addition to elastic neutron scattering, it has been used for (n,p) and (n,d) reaction experiments. The performance of the device has been illustrated in measurements of the (n,p) and (n,n) cross sections on 1H and 12C. LÄS MER
