   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; semiconductor materials; c-Si; a-Si; GaInP; TiO2; ZnO; nanostructuring; light manipulation functions; top-down fabrication; embossing; FDTD simulations; nanowires; nanopillars; nanodisks; microcones; optical response; reflectance; transmittance; absorbance; spectrophotometry; photoluminescence; Mie resonators; mode coupling; broadband anti-reflection; light extraction enhancement; optical sensing; optical color filters; color conversion; Optik och fotonik; Optics and Photonics;

   Abstract : Structuring of semiconductor materials is utilized in many optoelectronic devices, e.g, in order to make them more efficient, cost-effective, and/or to obtain specific wavelength-engineered responses. Semiconductor materials are widely used in optoelectronic devices due to their favorable optical and electric properties. READ MORE

4. 2. WO3 for reflective displays in color

   Author : Marika Gugole; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; reflective displays; electrochromism; plasmonic metasurfaces; structural colors;

   Abstract : Reflective displays, also known as electronic paper, are very attractive due to their low power consumption and great visibility under bright ambient light conditions. However, reflective displays in color are still limited on the market for two main reasons. READ MORE

5. 3. High Resolution Analysis of Halftone Prints : A Colorimetric and Multispectral Study

   Author : Daniel Nyström; Björn Kruse; Markku Hauta- Kasari; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Color imaging; Multispectral imaging; Halftone print; Dot gain; Image analysis; Bildanalys;

   Abstract : To reproduce color images in print, the continuous tone image is first transformed into a binary halftone image, producing various colors by discrete dots with varying area coverage. In halftone prints on paper, physical and optical dot gains generally occur, making the print look darker than expected, and making the modeling of halftone color reproduction a challenge. READ MORE

6. 4. Deterministic Silicon Pillar Assemblies and their Photonic Applications

   Author : Bikash Dev Choudhury; Anand Srinivasan; Harish Bhaskaran; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; nanopillar; nanowires; nanophotonics; nanofabrication; silicon; photovoltaics; second-harmonic generation; top-down approach; colloidal lithography; color filter; biosensor; Fysik; Physics; Teknisk materialvetenskap; Materials Science and Engineering;

   Abstract : It is of paramount importance to our society that the environment, life style, science and amusement flourish together in a balanced way. Some trends in this direction are the increased utilization of renewable energy, like solar photovoltaics; better health care products, for example advanced biosensors; high definition TV or high resolution cameras; and novel scientific tools for better understanding of scientific observations.

7. 5. Interpretation of gamma-ray burst X-ray and optical afterglow emission : From the central engine to the circumburst interaction

   Author : Liang Li; Felix Ryde; Fawad Hassan; Kim Page; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; gamma-ray bursts; central engine; afterglow; teoretisk fysik; Theoretical Physics;

   Abstract : Gamma-ray bursts are the largest electromagnetic explosions known to happen in the Universe and are associated with the collapse of stellar progenitors into blackholes. After an energetic prompt emission phase, lasting typically less than a minute and emitted in the gamma-rays, a long-lived afterglow phase starts. READ MORE
