1. 11. Excitonic effects in ZnO

   Författare :Shula Chen; Irina Buyanova; Weimin Chen; Ivan Ivanov; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : Zinc Oxide (ZnO) is an extensively researched II-VI wide bandgap semiconductor material. As a promising material for future optoelectronic and spintronic applications, it continues to attract enormous amount of interest. LÄS MER

3. 12. Transverse Chromatic Aberration and Vision: Quantification and Impact across the Visual Field

   Författare :Simon Winter; Linda Lundström; Stephen Burns; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; transverse chromatic aberration; lateral chromatic aberration; visual optics; peripheral vision; central vision; dispersion; ophthalmic optics and devices; optical effects on vision; retinal imaging; myopia; human eye; Fysik; Physics;

   Sammanfattning : The eye is our window to the world. Human vision has therefore been extensively studied over the years. However, in-depth studies are often either limited to our central visual field, or, when extended to the periphery, only correct optical errors related to a narrow spectrum of light. LÄS MER

4. 13. Computational fluid dynamics for dispersion calculation in urban surroundings

   Författare :Jan Burman; Anna Rutgersson; Sven-Erik Gryning; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; CFD; RANS; LES; Toxicological effects; Synthetic boundary conditions; Stable boundary layer.; Meteorologi; Meteorology;

   Sammanfattning : Increased knowledge on dispersion processes in urban environment will enhance the ability in the society to handle events where releases of toxic substances can occur. Also, the ability to increase preparedness at locations where such events potentially can emerge. LÄS MER

5. 14. MULTIFOCAL SPHERICAL FISH LENSES

   Författare :Yakir Gagnon; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Multifocal Lens; Adaptation; Dispersion; Spherical lens; Model; Fish; Ray-trace; Longitudinal Chromatic Aberration; Longitudinal Spherical Aberration; Modulation Transfer Function; Point Spread Function; Refractive Index Gradient;

   Sammanfattning : Vision is an important source of information for many animals. The lens plays a central role in the visual pathway and hence the ecology of these animals. Fish have spherically shaped crystalline lenses that contain a gradient of refractive index. Like all refracting elements, lens performance depends on the wavelength of the refracted light. LÄS MER

7. 15. Cellulose-based Nanocomposites – The Relationship between Structure and Properties

   Författare :Shiyu Geng; Kristiina Oksman; Laurent Matuana; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanocellulose; Nanocomposite; Dispersion; Poly vinyl acetate ; Poly lactic acid ; Alignment; Mechanical characteristics; Trä och bionanokompositer; Wood and Bionanocomposites;

   Sammanfattning : Nanocellulose materials extracted from various types of biomass have recently attracted significant attention. Due to their remarkable mechanical properties, large surface area and biodegradability, they can be promising reinforcements in nanocomposites. LÄS MER
