De sjeldne jordartene er en gruppe av grunnstoffer med like kjemiske egenskaper som omfatter lantanoidene og scandium og yttrium. I løpet av de siste tiårene har de blitt essensielle for moderne og grønn teknologi, men ...

Goldstone modes are massless particles resulting from spontaneous symmetry breaking. Although such modes are found in elementary particle physics as well as in condensed-matter systems like superfluid helium, superconductors, ...

High performance multicrystalline silicon wafers used in solar cell processing have been investigated with focus on quantification of the grain boundary effect on lifetime. The lifetime of a set of 16 wafers from different ...

The aluminium alloys for electrical conductivity applications are not grain refined since the addition of grain refiners might decrease their electrical conductivity by inserting impurities into the melt. Still, non-grain ...

This master thesis has the objective to improve the mechanical properties of Super Duplex steel by adding Elkem Grain Refiner (EGR). EGR is commercial grain refiner where the active element is cerium. Cerium is a strong ...

Belegg (coatinger) med grohindrende egenskaper har evnen til å hemme algevekst på konstruksjoner i marine næringer, i skipsfart, offshoreindustri, fiskeoppdrett og vannrensing. I dag brukes kobberoksid i flere relaterte ...

Fe–26Si–9B alloy is a promising high temperature phase change material (HTPCM), due to its high heat of fusion, small volumetric change, abundance, and low cost. Additionally, graphite has been identified as a promising ...

Dagens jernproduksjon (Fe) med masovner er et voksende miljøproblem, ettersom det brukes store mengder med råmaterialer som bidrar til mye CO2-utslipp. Direkte redusert jernproduksjon (DRI) med hydrogen (H2) har vekket ...

Silicon single crystal pulling process by Czochralski method is a multi-scale problem from atomistic scale defects up to several meters. This process involves several sources of instabilities e.g. crystal diameter perturbation, ...
