2. 21. Dispersion Engineering : Negative Refraction and Designed Surface Plasmons in Periodic Structures

   Author : Zhichao Ruan; Min Qiu; Henri Benisty; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; photonic crystal; dispersion property; negative refraction; surface plasmon polariton; designed surface plasmon; negative index material; layer-KKR method; finite-difference time-domain method; plane wave method; subwavelength imaging; open cavity; enhanced transmission; slowing light; Photonics; Fotonik;

   Abstract : The dispersion property of periodic structures is a hot research topic in the last decade. By exploiting dispersion properties, one can manipulate the propagation of electromagnetic waves, and produce effects that do not exist in conventional materials. READ MORE

4. 22. Piezoelectricity, Phase Stability, and Surface Diffusion in Multicomponent Nitrides

   Author : Christopher Tholander; Björn Alling; Lars Hultman; Ferenc Tasnádi; Liverius Lymperakis; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : The last hundred years have been full of scientific discoveries leading to technological advances, such as, computers, smart phones, etc. Most of the advances would not have been possible without new discoveries within the vast field of materials science. READ MORE

5. 23. Plasmons in Nanostructured Graphene

   Author : Tobias Wenger; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; linear response theory; surface plasmon-polaritons; Plasmons; surface electrodynamics; plasmonics; graphene; random phase approximation;

   Abstract : Plasmons, collective electron density oscillations, provide physicists with intriguing challenges and possibilities. The inherent many-body properties of the plasmons together with their ability to localize light into small volumes make the plasmons interesting from both a purely theoretical viewpoint and an applications point of view.

6. 24. Appearance characterisation of textured polymeric surfaces

   Author : Ingrid Arino; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; appearance; reflectance; polymer; colour; surface texture; gloss;

   Abstract : Appearance demands for industrial products are generally increasing since they are closely related to the overall quality impression. Consequently, there is a need to define appearance through its main descriptors, which are gloss, colour and surface texture, as well as the relations between them. READ MORE

7. 25. Effect of Surface Nanotopography on Blood-Biomaterial Interactions

   Author : Natalia Ferraz; Marjam Ott; Jaan Hong; Jan Carlsson; Tom Eirik Mollnes; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nanoporous alumina; nanotopography; biomaterial; platelets; complement system; macrophages; whole blood; inflammatory response; Chemistry; Kemi; Immunobiology; Immunbiologi; Immunologi; Immunology; Materialvetenskap; Materials Science;

   Abstract : Biologically inspired materials are being developed with the aim of improving the integration of medical implants and minimizing non-desirable host reactions. A promising strategy is the design of topographically patterned surfaces that resemble those found in the extracellular environment. READ MORE
