Accelerated hydrolysis method for producing partially degraded polyester microplastic fiber reference materials
Microplastic fibers (MPFs) from textiles significantly contribute to the microplastic (MP) load in many environmental matrices and have been shown to negatively impact the organisms therein. Most fate and effect studies to date rely on pristine reference MP materials that have limited relevance...
Accelerated hydrolysis method for producing partially degraded polyester microplastic fiber reference materials
Microplastic fibers (MPFs) from textiles contribute significantly to the microplastic (MP) load in many environmental matrices. MPFs have been shown to be readily ingested by a wide range of organisms representing multiple trophic levels and have been shown to negatively impact organisms. Most fate...
The low temperature crystallization of hydrogenated nitrile butadiene rubber (HNBR)
HNBR was analyzed following low temperature storage (between 0 °C and −50 °C) in order to measure the effects of cold crystallization during exposure close to, and below, the glass transition temperature (Tg). Differential scanning calorimetry (DSC), dynamic mechanical thermal analysis (DMTA) and...
Compatibility between semi-conductive LLDPE and hydrocarbon oil
Environmentally Friendly Cross-linking of Hydrolysed Polyacrylamide Gels
Hydrolysed Polyacrylamide (HPAM) gels have been used to block zones with high water permeability in oil reservoirs and thereby achieve a better sweep efficiency for enhanced oil recovery (EOR). The HPAM gels have traditionally been crosslinked by Cr (III) ions, and there is outermost interest to...
Numerical modeling of low temperature reeling of pipes
This paper presents an experimental/numerical study of low temperature pipe reeling, full-scale tests and small scale tests simulating the deformations and loads seen during reeling. The emphasis is on the polymer thermal insulation coating and the interfaces between the coating and steel pipe and...
The Effect of Hybrid Nanoparticle Additives on Epoxy-Nanocomposite Behavior and Morphology
Tiltak for å begrense kobberbruk i havbruk - optimalisere metoder for å impregnere not Sluttrapport
SINTEF har i samarbeid med 16 bedrifter tilknyttet Norske leverandører til havbruksnæringen (NLTH) gjennomført prosjektet ""Tiltak for å begrense kobberbruk i havbruk - optimalisere metoder for å impregnere not"", som er finansiert av Fiskeri- og havbruksnæringens forskningsfond. Begroing i havbruk...
