2. 1. Alternative Energy Harvesting and Conversion Systems Based on Nanostructured Heterostructures

   Author : Mojtaba Gilzad Kohan; Alberto Vomiero; Andrea Li Bassi; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; light harvesting; solar supercapacitors; energy conversion; Photovoltaic; energy storage; metal oxide semiconductors; Experimentell fysik; Experimental Physics;

   Abstract : Conversion and storage of the solar radiation into applicable forms of energy, using ubiquitous materials is of central importance that quests several disciplinary fields in both applied technology and fundamental science. Harnessing the solar energy received by the earth has the potential to replace the current sources of energy and it is imperative for sustainable development. READ MORE

4. 2. Industrial Digital Fabrication Using Inkjet Technology

   Author : Ingo Reinhold; Carl-Mikael Zetterling; Matti Mäntysalo; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; inkjet printing; droplet formation; digital fabrication; sintering; nanoparticles; printed electronics; Industrial Information and Control Systems; Industriella informations- och styrsystem; Media Technology; Medieteknik; Informations- och kommunikationsteknik; Information and Communication Technology;

   Abstract : The use of acoustic waves initiated by the deformation of a microchannel is one method for generating monodisperse, micrometer-sized droplets from small orifices and is employed in piezo-electric inkjet printheads. These printheads are used in both graphical printing and digital fabrication, where functionalities, such as optical, biological, electrical or mechanical, are being produced locally. READ MORE

5. 3. Electric Energy Conversion Systems : Wave Energy and Hydropower

   Author : Karin Thorburn; Mats Leijon; Petra Lundström; Uppsala universitet; []
   Keywords : Engineering physics; Ocean wave power; renewable energy; linear generator; farm simulation; Teknisk fysik;

   Abstract : Electric energy conversion is an important issue in today's society as our daily lives largely depend on the supplies of energy. Two energy sources are studied for conversion in the present thesis, ocean waves and hydropower. The work focuses on the generator and the transmission of its output to the electric grid. READ MORE

6. 4. Quantum acoustics with propagating phonons

   Author : Maria Ekström; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; phonon router; unidirectional transducer; phonon; Electromagnetically Induced Transparency; Surface acoustic wave; artificial atom; interdigital transducer; quantum acoustics; qubit; superconducting circuits;

   Abstract : Surface acoustic waves (SAWs) are mechanical vibrations that propagate on the surface of solids while dissipating little power, consequently enabling them to propagate freely over long distances. The speed and wavelength of SAWs are reduced a five order of magnitude compared to when light is used as a carrier at gigahertz frequencies. READ MORE

7. 5. Parametrically pumped superconducting circuits

   Author : Philip Krantz; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; SQUID; circuit quantum electrodynamics; Josephson junction; Superconducting circuits; resonators; parametric oscillators; quantum bit; pumpistor; quantum information;

   Abstract : In this licentiate thesis, I present the design, fabrication, and characterization of superconducting parametric resonators, for use in quantum information processing. These devices are quarter-wavelength coplanar waveguide resonators (~5 GHz), terminated at one end by a non-linear inductance provided by a SQUID (superconducting quantum interference device).
