  2. 1. Laser-Based Combustion and Trace-element Analysis

    Author : Yvonne Malmsten; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; laser-induced fluorescence; graphite furnace; trace element analysis; LEI; laser-enhanced ionisation; LIF; meta-stable; flow-tagging; NO; OH; counter-flow diffusion flame;

    Abstract : Laser spectroscopy has been utilised as a tool for combustion diagnostics and sensitive trace-element analysis. In the field of combustion analysis, a characterisation of a CH4/N2 - O2/N2 counter-flow diffusion flame has been performed using Laser-Induced Fluorescence (LIF). READ MORE

  6. 4. A scalable furnace technique to grow silicon nanoparticles for high-performance Li-ion battery anodes

    Author : Rohan Patil; Jonas Örtegren; Shizhao Xiong; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Li Ion Battery; Aerogel-Based Anodes; Novel Method; silicon nanoparticles; Nanographite; High Capacity;

    Abstract : Lithium-ion batteries are one of the key technologies to address the global climate challenge. Higher battery capacity could also be seen as indirectly influencing the entire value chain. One way to increase capacity is to add silicon to the graphite anode, since silicon can store much more lithium ions than graphite. READ MORE
