2. 1. Gold-Based Nanoparticles and Thin Films : Applications to Green Nanotechnology

   Author : Pia Lansåker; Claes-Göran Granqvist; Gunnar Niklasson; Ulf Helmersson; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; green nanotechnology; transparent conductors; nanoparticles; gold coalescence; substrate effect; temperature effect; Fysik; Physics;

   Abstract : The use of gold-based nanoparticles and thin films is very promising when it comes to improving several green nanotechnologies. Therefore, in order to further their use in applications such as electrochromic devices, photovoltaics, light-emitting diodes and photocatalysis, the aim of this work was to study the growth of gold-based nanoparticles and thin films.

4. 2. Environmental Assessment and Strategic Technology Choice : The Case of Renewable Transport Fuels

   Author : Karl Hillman; Björn Sandén; Ken Green; Göteborg Chalmers Tekniska Högskola Miljösystemanalys Institutionen för energi och miljö; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; environmental assessment; life cycle assessment LCA ; socio-technical change; strategic technology choice; renewable fuels;

   Abstract : The scale of the required changes is huge, and time is limited if we are to avoid the most severe effects of climate change. To reduce greenhouse gas emissions from road transport, several fuels and electricity originating from renewable energy sources have been proposed, all of them in different stages of development and with various and shifting environmental impacts.

5. 3. Particle image velocimetry in practice

   Author : Torbjörn Green; Kristian Angele; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

   Abstract : Experimental fluid mechanics has for a long time been used to visualize flow phenomenon. An early pioneer was Ludwig Prandtl who used aluminum particles in water flumes to describe the flow in a qualitative manner. In line with the rapid development of Computational Fluid Dynamics, CFD, the need for new validation tools has increased. READ MORE

6. 4. PIV in Practice

   Author : Torbjörn Green; Andreas Fouras; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

   Abstract : Experimental fluid mechanics has for a long time been used to visualize flow phenomenonqualitatively. Traditionally, visualization has been done with dye or tracer particle dueto their ability to follow the flow pattern well. READ MORE
