Additive manufacturing of Duplex Stainless Steels (DSS) and Super Duplex Stainless Steels (SDSS) has been successfully demonstrated using LPBF in recent years, however, both alloys feature an almost fully ferritic microstructure in the as-built condition due to the fast cooling rates associated with...

Autonomous field robots are being developed for picking of fruit, where each fruit needs to be individually graded and handled. There is therefore a need for rapid and non-destructive sensing to measure critical fruit quality parameters. In this article we report how total soluble solids (TSS), a...

Laser-arc hybrid welding (LAHW) is an efficient and promising joining method for offshore structures made from metallic alloys. Under a high-power laser output, a keyhole is formed that efficiently melts a metal and provides high penetration depths compared to shallow and wide welds made by...

Despite the cost reductions of green hydrogen, it is uncertain when cost parity with blue hydrogen will be achieved. Beyond technology costs, electricity and natural gas prices, hydrogen’s competitiveness will be increasingly determined by carbon costs or regulation associated with its life-cycle...

To investigate the structural behaviors of Al3+ in aluminosilicate systems, the microstructural characteristics of CaO–SiO2-based glassy samples with various Al2O3 contents were examined quantitatively by Raman spectroscopy and 27Al MAS NMR. A sequence of multiple model clusters of aluminosilicate...

Laboratory experiments provide knowledge of species-specific effects thresholds that are used to parameterize impact assessment models of oil contamination on marine ecosystems. Such experiments typically place individuals of species and life stages in tanks with different contaminant concentrations...

Metabolite-level regulation of enzyme activity is important for microbes to cope with environmental shifts. Knowledge of such regulations can also guide strain engineering for biotechnology. Here we apply limited proteolysis-small molecule mapping (LiP-SMap) to identify and compare metabolite...

This paper proposes a common ICT reference architecture to overcome current application orgeographic "silos" in digital maritime communication. The architecture is called reference architecturesince it only specifies the generic case. If desired, it can be developed into a more concrete architecture...

Prosjektansvarlig har vært Brødrene Berg AS ved Rolf Jarle Andreassen. Prosjektet ble finansiert av FHF og Innovasjon Norge. Til sammen 8 bedrifter har deltatt aktivt med egeninnsats og gjennomføring av forsøk. Målsettingen var å optimalisere tidspunkt for inntak av tørrfisk og finne best...

Our understanding of the failure mechanisms of coatings, for example, cathodic disbonding, corrosion creep, blistering, and cracking, have been developed to a high level over the past decades. However, knowing what actually causes coatings to fail in the field is also important. Several atmospheric...

Fish early life stages are well known for their sensitivity to crude oil exposure. However, the effect of crude oil exposure on adults and their gametes during their spawning period is not well studied. Polar cod, a key arctic fish, may be at risk for crude oil exposure during this potentially...

Deep wells in soft formations are completed with a steel tube (“casing”) that isolates the well from the surrounding rock. The annulus between the casing and the rock is usually left open in long sections of the well, thus creating a potential pathway for leakage which must somehow be sealed by a...

The demand for engineered scaffolds capable of delivering multiple cues to cells continues to grow as the interplay between cell fate with microenvironmental and external cues is revealed. Emphasis has been given to develop stimuli-responsive scaffolds. These scaffolds are designed to sense an...

Nitrogen-doped activated carbons with controlled micro- and mesoporosity were obtained from wood and wastes via chemical processing using pre-treatment (pyrolysis at 500 °C and hydrothermally carbonization at 250 °C) and evaluated as oxygen reduction catalysts for further application in fuel cells...

Tilbakemeldinger fra industri og marked viser at kvaliteten på bearbeidede hyseprodukt fra Norge ikke alltid er god nok for alle segmenter i markedet. Bløt muskel, spalting og blodfeil er typiske kvalitetsutfordringer. Det er åpenbart rom for forbedringer i dagens fangst- og produksjonsregime og...
