Gradual Reduction in Sodium Content in Cooked Ham, with Corresponding Change in Sensorial Properties Measured by Sensory Evaluation and a Multimodal Machine Vision System
(Journal article; Peer reviewed, 2015)The European diet today generally contains too much sodium (Na+). A partial substitution of NaCl by KCl has shown to be a promising method for reducing sodium content. The aim of this work was to investigate the sensorial ... -
Grain boundary effect on lifetime in high performance multicrystalline silicon during solar cell processing
(Journal article; Peer reviewed, 2016)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 ... -
Grain boundary segregation in Pd-Cu-Ag alloys for high permeability hydrogen separation membranes
(Journal article; Peer reviewed, 2018)Dense metal membranes that are based on palladium (Pd) are promising for hydrogen separation and production due to their high selectivity and permeability. Optimization of alloy composition has normally focused on bulk ... -
Grain boundary structures and their correlation with intergranular corrosion in an extruded Al-Mg-Si-Cu alloy
