    Abstract : LIBs have become an ideal choice in the EVs batteries and stationary storage applications due to their invaluable advantages. The demand for LIBs is projected to increase due to the growth in the sale of EVs. READ MORE

  4. 23. Cobalt and nickel concentrations in the Uppsala clay deposits : solubility and risk assessment

    University essay from SLU/Dept. of Soil and Environment

    Author : Ali Reza Sadeghi; [2020]
    Keywords : heavy metals; soil contanimation; geochemically active fraction; leaching test; guideline value; site-specific guideline value;

    Abstract : Heavy metals create a contamination problem in soils. Examples of heavy metals are Ni, Co, and Cu. Soil environment and minerals existing in the soil such as Fe and Mn oxides affect the presence of these heavy metals. In this thesis, the cobalt and nickel concentrations of selected soil samples from different locations in Uppsala were determined. READ MORE

  5. 24. Effect of conformal cooling in Additive Manufactured inserts on properties of high pressure die cast aluminum component

    University essay from Jönköping University

    Author : Ruslan Sevastopolev; [2020]
    Keywords : High Pressure Die Casting HPDC ; Additive Manufacturing AM ; Aluminum Al ; Tensile test; Cooling channels; Conformal cooling; Laser Based Power Bed Fusion of Metals PBF-LB M ; Microstructure; Secondary Dendrite Arm Spacing SDAS .;

    Abstract : Additive manufacturing can bring several advantages in tooling applications especially hot working tooling as high pressure die casting. Printing of conformal cooling channels can lead to improved cooling and faster solidification, which, in turn, can possibly result in better quality of the cast part. READ MORE

  6. 25. Metal mobility and transport from an oil-shale mine, Lake Nõmmejärv, Estonia
