2. 1. Fabrication and characterization of single luminescing quantum dots from 1D silicon nanostructures

   Author : Benjamin Bruhn; Jan Linnros; Luca Dal Negro; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; silicon; quantum dot; nanocrystal; nanowire; nanostructure; photoluminescence;

   Abstract : Silicon as a mono-crystalline bulk semiconductor is today the predominant material in many integrated electronic and photovoltaic applications. This has not been the case in lighting technology, since due to its indirect bandgap nature bulk silicon is an inherently poor light emitter. READ MORE

   Abstract : The purpose of this thesis was to develop an economical, sustainable, and environmentally friendly straw Medium Density Fibreboard (MDF) process, capable of full-scale manufacturing and to produce MDF of requested quality. The investigated straw was based on wheat (Triticum aestivum L.) and rice (Oryzae sativa L.). READ MORE

5. 3. Recycling of TiO2 Pigments from Waste Paint: Process Development, Surface Analysis, and Characterization

   Author : Mikael Karlsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Recycling; Recovery; Paint; Titanium dioxide; Waste.; Municipal solid waste handling; Pyrolysis; Pigment;

   Abstract : Pigments are commonly used in paint, plastic and paper products and titanium dioxide (TiO2), the most important white pigment, accounts for approximately 70 % of the total volume of all pigments used today. Minerals containing TiO2 are relatively abundant in the earth’s crust. READ MORE

6. 4. Marine silicon cycle through the Cenozoic

   Author : Guillaume Fontorbe; Kvartärgeologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Si isotopes; Paleogene; PETM; glacial-interglacial; ocean circulation;

   Abstract : Silicon (Si) cycle is one of Earth's major biogeochemical cycles. Furthermore, the dissolved form of Si (DSi) is an essential nutrient for both terrestrial and marine ecosystems. READ MORE

7. 5. Applications of Artificial Microcavities in Wafer Bonded Silicon

   Author : Zhaohua Xiao; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : A novel sensor structure has been investigated and extensively studied. The device can be used as a pressure sensor, a voltage measuring device and as an optical modulator. The sensor was made using thermal bonding and micromachining techniques. READ MORE
