  1. 1. Sustainable Recycling of Electrolytes for Vanadium Redox Flow Batteries : Method development and Review (Bachelor Thesis)

    University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Author : Reza Doulati; [2023]
    Keywords : vanadium redox flow batteries VRFB; eco-friendly recycling; precipitation of vanadium; vanadium oxides; Energy storage system; ESS; circular economy; sustainable recycling method;

    Abstract : Vanadium Redox Flow Batteries VRFBs are promising energy storage systems with highly recyclable electrolytes. The recycling of these systems usually involves ammonium-based salt precipitation steps, which produce toxicgases and contaminated water as waste. READ MORE

  3. 2. Characterization of Secondary Carbides in Low-Alloyed Martensitic Model Alloy Tool Steels

    University essay from KTH/Materialvetenskap

    Author : Jubica Jubica; [2020]
    Keywords : martensitic steel; secondary hardening; precipitation; STEM; EDS; Prisma; size distribution; martensitiskt stål; sekundärhärdning; utskiljning; STEM; EDS; PRISMA; storleksfördelning;

    Abstract : The development of tool steels for making and shaping other materials requires a better understanding of the material's properties during manufacture. These high-quality steels include many alloying elements, which give increased hardness during tempering. For producing hardened microstructures, austenite generation is essential. READ MORE

  4. 3. Precipitation Study in a High Temperature Austenitic Stainless Steel using Low Voltage Energy Dispersive X-ray Spectroscopy
