  2. 1. Additive manufacturing of fused silica glass

    Author : Pawel Maniewski; Michael Fokine; Fredrik Laurell; Daniel Milanese; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; laser cladding; 3d printing; additive manufacturing; glass; fused silica; laser; scattering; silica; Optik och fotonik; Optics and Photonics; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : Additive Manufacturing, of both metals and polymers, has seen rapid development in recent years, whereas the progress in glass has been rather slow. Today, glass can be considered the last frontier without a specialized 3D printing method available. READ MORE

  4. 2. Crystallization in additive manufacturing of metallic glass

    Author : Anders Ericsson; Hållfasthetslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Amorphous metals; Crystallization; Laser powder bed fusion; Neutron scattering; Phase-field theory; Classical nucleation theory;

    Abstract : Metallic glasses are non-crystalline metals that are obtained by rapid cooling of the melt to bypass crystallization. The amorphous atomic structure shows enhanced properties relative to the crystalline counterpart. For example, enhanced mechanical properties, improved corrosion resistance, as well as excellent soft magnetic properties. READ MORE

  5. 3. Femtosecond Laser Microfabrication of Glasses and 2D Materials for Photonics and Energy Storage

    Author : Po-Han Huang; Frank Niklaus; Göran Stemme; Kristinn Gylfason; Yves Bellouard; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Femtosecond laser; 3D printing; self-organized nanogratings; micromachining; silica glass; silicon-rich glass; hydrogen silsesquioxane; photonic microdevice; microsupercapacitor; 2D materials; direct ink writing; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Femtosecond laser-based fabrication technologies have seen rapid developments in the past decades, thanks to the capability of femtosecond lasers to induce localized multiphoton absorption in materials. Multiphoton absorption can result in various material modifications that can be leveraged for additive and subtractive manufacturing. READ MORE

  6. 4. Glass-forming ternary blends: towards stable Polymer Solar Cells

    Author : Amaia Diaz de Zerio Mendaza; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; organic photovoltaics; glass formation.; fullerenes; ternary blends; thermal stability;

    Abstract : The globally increasing use of electricity goes hand in hand with climate change and the gradual depletion of fossil sources of fuel. To address these challenges renewable sources of energy are in high demand. READ MORE

  7. 5. Ultra precision metrology : the key for mask lithography and manufacturing of high definition displays

    Author : Peter Ekberg; Lars Mattsson; Torgny Carlsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ultra precision metrology; LCD-display; OLED-display; nm-resolution; large area; random phase measurement; acousto-optic deflection; scanning; 2D measurement; mask; CCD; CMOS; image processing; edge detection; TECHNOLOGY; TEKNIKVETENSKAP; Manufacturing engineering; Produktionsteknik;

    Abstract : Metrology is the science of measurement. It is also a prerequisite for maintaining a high quality in all manufacturing processes. In this thesis we will present the demands and solutions for ultra-precision metrology in the manufacturing of lithography masks for the TV-display industry. READ MORE
