   Author : Olivier Donzel-Gargand; Marika Edoff; Lionel Fourdrinier; Thomas Thersleff; Daniel Abou-Ras; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electron microscopy; TEM; STEM; EELS; EDS; solar cells; CIGS; ACIGS; CZTS; post deposition treatment; KF; RbF; buffer layers; interfaces; inter layers; barrier layers; passivation layers; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

   Abstract : The CIS solar cell family features both a high stability and world-class performances. They can be deposited on a wide variety of substrates and absorb the entire solar spectrum only using a thickness of a few micrometers. READ MORE

4. 2. Phosphorylated Monomolecular Layers : Design, Synthesis, Characterization and Application

   Author : Johan Ekeroth; Karin Caldwell; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : This thesis describes the design, synthesis and characterization of organo-phosphatemonomolecular layers, so called self-assembled monolayers, using the strategy of linking organosulfur substances to a gold surface. Moreover there is also a paper included, which describes the development of synthetic pathways to various phospholipids, for which I have developed an interest in later projects. READ MORE

5. 3. Studies of stratocumulus-topped boundary layers using a numerical weather prediction model

   Author : Robert Sigg; Peter Duynkereke; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; meteorologi; Meteorology;

   Abstract : Persistent stratocumulus clouds are commonly observed in many areas on Earth. In general, stratocumulus clouds cool the Earth-atmosphere system due to their influence on the radiation budget. It is therefore essential to describe such clouds accurately in climate and numerical weather prediction models. READ MORE

6. 4. Simulations of turbulent boundary layers with suction and pressure gradients

   Author : Alexandra Bobke; Philipp Schlatter; Ramis Örlü; Ayse Gul Gungor; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; boundary layers; near-wall turbulence; history effects; asymptotic suction boundary layers; large-eddy simulation;

   Abstract : The focus of the present licentiate thesis is on the effect of suction and pressure gradients on turbulent boundary-layer flows, which are investigated separately through performing numerical simulations.The first part aims at assessing history and development effects on adverse pressure-gradient (APG) turbulent boundary layers (TBL).

   Abstract : The global trend towards quieter environments has been one of the key topics of acoustics research for years. The recent tightening of the regulations on noise exposure as well as the many reports on the impact of noise on human health confirm this situation and stress ever more the need for innovative mitigation strategies.
