   Sammanfattning : Na+,K+-ATPase is one of the most important proteins in the mammalian cell. It creates sodium and potassium gradients which are fundamental for the membrane potential and sodium-dependent secondary active transport. LÄS MER

4. 23. Effects of increased UV-B radiation on the lichen Cladonia arbuscula spp. mitis: UV-absorbing pigments and DNA damage

   Författare :Roberta Buffoni Hall; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Systematic botany; taxonomy; morphology; phytogeography; chemotaxonomy. Physiology of nonvascular plants; kemotaxonomi. Växters fysiologi inte kärlväxter .; Systematisk botanik; taxonomi; morfologi;

   Sammanfattning : Lichens, a form of symbiosis between a fungal and a photosynthetic partner, are believed to be a group that evolved early in the history of terrestrial life. As a consequence, they probably experienced higher ultraviolet (UV) radiation fluxes than at present. LÄS MER

5. 24. Molecular Processes in Dynamic Wetting : Du som saknar dator/datorvana kan kontakta Cathrine Bergh, [email protected] för information

   Författare :Petter Johansson; Berk Hess; Erik Lindahl; Guillaume Galliero; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; contact lines; nanodroplets; computational physics; molecular dynamics; fluid dynamics; multi-phase flows; electrowetting; Biologisk fysik; Biological Physics;

   Sammanfattning : The spreading of liquids onto and over surfaces is a fundamental process in nature. It is present in all forms and sizes: From rivers carving through landscapes, to our blood stream transporting nutrients to cells, and even single water molecules moving through channels into these cells.

7. 25. Optimization of resonant all-dielectric nanoparticles for optical manipulation and light management

   Författare :Nils Odebo Länk; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; FDTD; Nanophotonics; Metasurfaces; Optical Forces; All-dielectric; Perfect Absorption; Silicon;

   Sammanfattning : The resonant interaction between light and matter lies at the heart of nanophotonics research. In particular, nanoparticles that possess optical resonances in the visible spectral range have been avidly studied and employed for various technical and biological applications in the last two decades.
