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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Pia Lansåker; Claes-Göran Granqvist; Gunnar Niklasson; Ulf Helmersson; [2012]
    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.

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

    University dissertation from Gothenburg : Chalmers University of Technology

    Author : Karl Hillman; Björn Sandén; Ken Green; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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.

  3. 3. On bacterial formats in protein library technology

    University dissertation from Stockholm : KTH

    Author : Per-Åke Löfdahl; Per-Åke Nygren; Mikael Widersten; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Affibody molecule; β-lactamase; combinatorial library; green fluorescent protein GFP ; protein engineering; protein fragment complementation assay PCA ; selection; TEVprotease; TNF-α; TECHNOLOGY Bioengineering; TEKNIKVETENSKAP Bioteknik; TECHNOLOGY Bioengineering Enzyme engineering; TEKNIKVETENSKAP Bioteknik Enzymteknik;

    Abstract : Millions of years of evolution have resulted in an immense number of different proteins, which participate in virtually every process within cells and thus are of utmost importance for allknown forms of life. In addition, there are several examples of natural proteins which have found use in applications outside their natural environment, such as the use of enzymes infood industry and washing powders or the use of antibodies in diagnostic, bioseparation or therapeutic applications.

  4. 4. Particle image velocimetry in practice

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Torbjörn Green; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering mechanics - Fluid mechanics; Teknisk mekanik - Strömningsmekanik; 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

  5. 5. PIV in Practice

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Torbjörn Green; [2011]
    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
