  2. 1. Tin-based Glasses: Structure and Electrochemical Properties

    Author : Cecilia Gejke; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Li-ion battery; anode; borate glasses; phosphate glasses; tin; reverse Monte Carlo simulation; Raman spectroscopy; infrared spectroscopy; neutron diffraction;

    Abstract : This thesis presents an investigation of microscopic structure and electrochemical properties, and their relationship, for various tin-based borate, phosphate and borophosphate glasses. Tin-based glasses have attracted a lot of scientific interest as anode materials in Li-ion batteries. READ MORE

  4. 2. 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

  5. 3. Magnetism of manganites, semiconductors and spin glasses

    Author : Roland Mathieu; Ian Campbell; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; fasta tillståndets fysik; Solid State Physics;

    Abstract : Magnetic and electrical properties of selected compounds containing manganese (Mn) are investigated by SQUID magnetometry and transport measurements.(Ga,Mn)As is a magnetic semiconductor obtained from GaAs by substituting Ga3+ for Mn2+. Mn acts in the alloy as a magnetic impurity, as well as a hole dopant. READ MORE

  6. 4. Crystallization of glasses in the system (Zr)-Y-Si-Al-O-(N)

    Author : Peter Vomacka; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materialteknik; Engineering Materials;

    Abstract : Glass is a group of materials that has been used for structural and functional purposes for many centuries. Nevertheless, interest in the science and technology of glass has expanded significantly in recent years as a result of the need to develop new materials for advanced applications. READ MORE

  7. 5. Minuscular sculpturing

    Author : Greger Thornell; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; materialvetenskap; Materials Science;

    Abstract : Most of the processes employed in microstructure technology have been adopted from the fabrication scheme of integrated circuits (IC). Although being extremely reliable and cost efficient, they suffer from poor material and geometrical flexibility. READ MORE
