    Keywords : NATURAL SCIENCES; NATURVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Rare earth elements; hybrid electric vehicles; recycle; nickel; cobalt; precipitation; anti-solvent crystallization; selective roasting; Sällsynta jordartsmetaller; hybridelektriska fordon; återvinning; nickel; kobolt; utfällning; förträngningskristallisation; selektiv rostning; Chemical Engineering; Kemiteknik;

    Abstract : Rare earth elements (REE) are a group of elements that are of critical importance in numerous technological applications, including “green technologies” such as wind turbines and hybrid car batteries. When the criticality of applications is considered, problems in supply has brought the option of effective secondary resource utilization into consideration. READ MORE

  4. 2. Deployment Simulations of a Composite Boom for Small Satellites

    Author : Pau Mallol Parera; Gunnar Tibert; Keith Seffen; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; small satellites; deployable structures; high packaging ratio; composites; bi-stable; gravity off-loading system; små satelliter; utfällbara strukturer; kompakt ihoppackning; kompositer; bistabil; tyngdkraftskompenserande system;

    Abstract : The use of small satellites is rapidly growing, especially satellites with masses between 1 and 10 kg and few litres of volume. The main reasons are due to the low development time and cost. Electronics miniaturization and high density integration is enabling the small satellites class to perform more and better tasks and at a lower cost. READ MORE
