1. 1. Technology Platforms: Organizing and Assessing Technological Knowledge to Support its Reuse in New Applications

   Författare :Daniel Corin Stig; Chalmers University of Technology; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; technology management; knowledge reuse; technology platforms; platform thinking; core capabilities; technology development; technology reuse; technology transfer; knowledge management; knowledge repositories;

   Sammanfattning : Companies that develop a wide range of products often strive to exploit opportunities for synergy among them. Many products that cannot share components can still offer opportunities for synergy as they build upon the same technologies and know-how for their development and production. LÄS MER

3. 2. Out of the Dark and into the Light - Microscopic Analysis of Bright, Dark and Trapped Excitons

   Författare :Maja Feierabend; Chalmers University of Technology; []
   Nyckelord :NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; density matrix formalism; localized states; impurities; dark excitons; strain; transition metal dichalcogenides; Bloch equations;

   Sammanfattning : Atomically thin transition metal dichalcogenides (TMDs) have been in the focus of current research due to their efficient light-matter interaction, as well as the remarkably strong Coulomb interaction that leads to tightly bound excitons. Due to their unique band structure, TMDs show a variety of optically accessible bright and inaccessible dark excitons. LÄS MER

4. 3. Applications of Microwave Heating of Foods

   Författare :Birgitta Wäppling-Raaholt; Birgitta Raaholt; Chalmers University of Technology; []
   Nyckelord :NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; modelling of microwave heating; microwave-assisted HTST processing; product quality.; heat transfer; microwave heating; microwave oven; heating uniformity; microwave cavity; tubular microwave in-flow processing;

   Sammanfattning : AbstractMicrowave heating of foods offers rapid and flexible heating both for consumer and industrial applications, with several advantages, such as reduced processing time (due to volumetric heating and reduced coming-up times (heating time required to reach the desired target temperature), selective heating, increased process flexibility and efficient heating (volumetric heating of the food does not require heating of a surrounding medium or package). However, successful installations requireknowledge in process design. LÄS MER

5. 4. Polymer-Based Low-Cost Micromachining of Gap Waveguide Components

   Författare :Sadia Farjana; Chalmers University of Technology; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; mmWave; Polymer microfabrication; sub-mmWave; Dry film photoresist; MEMS; Gap waveguide; Antenna; Waveguide.; Injection molding;

   Sammanfattning : The millimeter-wave (mmWave) and sub-millimeter-wave (sub-mmWave) frequency bands have gained significant attention over the past few years due to the growth of commercial wireless applications. As the operating frequency approaches these higher frequencies, the dimensions of the waveguide-based components continue to decrease. LÄS MER

7. 5. Optical manipulation and heating of gold nanoparticles near interfaces

   Författare :Daniel Andrén; Chalmers University of Technology; []
   Nyckelord :NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; LSPR spectroscopy; particle-surface separation distance; thermal reshaping; TIRM; nanomotor; plasmonics; photothermal effects; Brownian dynamics; gold nanorod; optical tweezers;

   Sammanfattning : By focusing laser light to small volumes, its momentum can be used to trap and manipulate objects in the size range from cells down to single atoms. Devices using this effect are called optical tweezers, and have found use in measuring and applying minuscule forces and torques, contributed to deepening our knowledge of molecular motors, unraveling the mechanics of cells and DNA, and better understand statistical mechanics and hydrodynamic interactions at the nanoscale.
