1. Characterization of WC-Co tools used for machining of Alloy 718 under the influence of high-pressure coolant supply
Sammanfattning : The use of high-pressure jets for supply of coolant to the cutting zone has the potential to significantly increase the productivity and process stability when machining difficult-to-cut materials such as Ni-based superalloys. Apart from better chip-breakability, the jets enable the coolant to reach closer to the cutting edge and hence enhance its capability to dissipate heat. LÄS MER
2. Modified Starches in aqueous and plastisol coating
Sammanfattning : The interest for coatings containing renewable materials has enlarged in the last decade. Materials from the nature are investigated like starch, cellulose derivatives, protein (gelatin), chitosane by many. In this study potato starch has been used. LÄS MER
3. Wood hydrolysate Barriers
Sammanfattning : Wood hemicellulose is an abundant but fairly unexploited renewable feedstock. Recent studies have shown that hemicelluloses have a large potential for use in the food packaging industry as a sustainable alternative to the conventional oxygen-barrier materials used today. LÄS MER
4. Protein-based Packaging Films, Sheets and Composites: Process Development and Functional Properties
Sammanfattning : The depletion of the petroleum resources and a number of environmental concerns led to considerable research efforts in the field of biodegradable materials over the last few decades. Of the diverse range of biopolymers, wheat gluten (WG) stands out as an alternative to synthetic plastics in packaging applications due to its attractive combination of flexibility and strength, high gas barrier properties under low humidity conditions and renewability.
