1. 1. Novel Porous Films from Functional and Biocompatible Linear-Dendritic Hybrids

   Författare :Marie V. Walter; Michael Malkoch; Steve P. Rannard; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; poly ethylene glycol ; poly caprolactone ; linear-dendritic hybrid; click chemistry; CuAAC; thiol-ene chemistry; amphiphilic polymer; honeycomb film; isoporous film; thiol; dendrimer;

   Sammanfattning : In the last decades, the fabrication of ordered nano- and microporous structures has attracted increasing interest due to their specific properties and multiple possible applications in electronics, as templates or in the biological field. The development of such materials has been favored by the introduction of the simple breath-figure templating method in the 1990’s. LÄS MER

   Sammanfattning : GaN and its alloys with Al and In belong to the group III nitride semiconductors and are today the materials of choice for efficient white light emitting diodes (LEDs) enabling energy saving solid state lighting. Currently, there is a great interest in the development of novel inexpensive techniques to fabricate hybrid LEDs combining high quality III-N quantum well (QW) structures with inexpensive colloidal nanoparticles or conjugated polymers.

5. 4. Properties of Multifunctional Oxide Thin Films Despostied by Ink-jet Printing

   Författare :Mei Fang; Lyubov Belova; K. Venkat Rao; Gillian Gehring; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ink-jet printing; oixde; thin film; ink; suspension; dye sensitized solar cell; functional properties; magnetism; diluted magnetic semiconductors;

   Sammanfattning : Ink-jet printing offers an ideal answer to the emerging trends and demands of depositing at ambient temperatures picoliter droplets of oxide solutions into functional thin films and device components with a high degree of pixel precision. It is a direct single-step mask-free patterning technique that enables multi-layer and 3D patterning. LÄS MER

7. 5. New Functions for Old Genes in the Mouse Placenta

   Författare :Umashankar Singh; Reinald Fundele; Anne C Ferguson-Smith; Uppsala universitet; []
   Nyckelord :Developmental biology; hybrid dysgenesis effects; placental hyperplasia; functional screening; giant cell; glycogen cell; Utvecklingsbiologi;

   Sammanfattning : Different species are separated by pre-zygotic reproductive barriers which impede gene flow between them. Rarely, when pre-zygotic barriers break down, interspecific hybrids are produced that display abnormal phenotypes, collectively called hybrid dysgenesis effects. LÄS MER
