An isothermal microcalorimeter has been used to study the effect of solid copper in hexadecane, vegetable oil (ester) and mineral oil. The experiments have shown a catalytic effect of copper in oxidation of hydrocarbons and also the anti-oxidative effect of dibenzyl disulphide when combined with...
Apart from their archetypic use in anaerobic digestion (AD) methanogenic archaea are targeted for a wide range of applications. Using different methanogenic archaea for one specific application requires the optimization of culture media to enable the growth of different strains under identical...
SINTEF Fiskeri og havbruk AS (SINTEF) har bistått Bodø kommune med å gi innspill til hvilke valgmuligheter har Bodø kommune når det gjelder innholdet i en konsekvensutredning for Skjerstadfjorden og Saltstraumen. SINTEF har også gitt innspill til de viktigste temaene/problemstillingene...
In Norway’s ‘Framework Plan for kindergartens’ digital tools are to be implemented for learning, play and creativity. Implicitly the concept of digital tools, or ICTs, tend to be tablets, computers, and interactive whiteboards, smartphones are as such not taken into account. However, we find that...
To determine biotransformation of components in crude oil dispersions in the presence of feces from marine copepods, dispersed oil was incubated alone, with the addition of clean or oil-containing feces. We hypothesized that the feces would contribute with nutrients to bacteria, and higher...
The bandstructure of ⟨110⟩⟨110⟩ silicon nano wires (SiNWs) with diameters (d) up to 6.1 nm were studied using density functional theory. Three types of surface termination were investigated: H, F, and OH; all giving quantum confinement induced direct bandgaps in the investigated size range...
Atomically thin transition-metal dichalcogenides (MoS2, WSe2, etc.) have long been touted as promising materials for gas detection because of their tunable band gaps; however, the sensing mechanism, based on a charge-transfer process, has not been fully explored. Here, we directly observe the effect...
The use of silicon (Si) in the form of nanoparticles is one of the most promising routes for boosting the capacity of modern Li‐ion batteries. Many parameters influence the performance of Si making the comparison of materials complicated. The present work demonstrates a direct comparison of Si...
Xylan is a highly abundant biopolymer having, with the right modifications, outstanding chemical and physiochemical properties. Utilization of xylan remains limited as methodology for xylan processing is not optimal and relevant enzymes for efficient modification of the long-chain polymer are yet...
Plasmonically active nanoparticles offer a promising pathway to extend the absorption range of photocatalysts. While not necessarily catalytically active themselves, these particles allow the absorption of lower energy photons in wide band gap photocatalysts. Here, we present A-site excess SrTiO...
Silicon is often regarded as a likely candidate to replace graphite as the main active anode material in next-generation lithium ion batteries; however, a number of problems impacting its cycle stability have limited its commercial relevance. One approach to solving these issues involves the use of...
The rates of ingestion of oil microdroplets and oil fouling were investigated in the zooplankton filter-feeder Calanus finmarchicus (Gunnerus, 1770) at 3 concentrations of oil dispersions ranging from 0.25 mg/L to 5.6 mg/L. To compare responses to mechanically and chemically dispersed oil, the...
Oil droplets may form and disperse in the water column after an accidental spill of crude oil or petroleum products at sea. Micro-sized oil droplets may be available for filter feeding organisms, such as the copepod Calanus finmarchicus, which has been shown to filter oil droplets. In the present...
Under en workshop omhandlende biomassekontroll avholdt den 23. juni 2009 på Gardermoen, kom det frem at det er et behov for å kartlegge konsekvensene av feilestimering av biomasse under produksjon av fisk i sjøbasert oppdrett. Marine Harvest Norge AS, Norbit AS og Akvagroup ASA inngikk et samarbeid...
The capability of battery materials to deliver not only high lithium storage capacity, but also the ability to operate at high charge/discharge rates is an essential property for development of new batteries. In the present work, the influence on the charge/discharge rate behaviour of...
Plasmonic structures can help enhance optical activity in the ultraviolet (UV) region and therefore enhancing photocatalytic reactions and the detection of organic and biological species. Most plasmonic structures are composed of Ag or Au. However, producing structures small enough for optical...
In this study, α-MoO3 two-dimensional (2D) layers and thin films were synthesized using pulsed laser deposition technique. X-ray diffraction and Raman spectroscopy confirm the formation of anisotropic α-MoO3. Atomic Force Microscopy images show the evolution of morphology from 2D layers to oriented...
Zooplankton are suggested to be biotic contributors to the transport and weathering of oil in marine environments due to their ingestion of oil. In the present experiment, feeding activity and microbial communities in feces from Calanus finmarchicus feeding in oil dispersions were characterized...
In traditional reinforced concrete, the alkaline pore solution which passivates the steel rebars will get neutralized with time in an exposed environment. Therefore, to prevent corrosion initiation, the permeability of the concrete is reduced and extra-thick concrete covers the steel rebars...
Background and aim Patients with cancer are at high risk of malnutrition, yet relevant ICD-10 codes for malnutrition are underutilized in cancer clinics. Understanding oncologists' perspectives is crucial for optimizing malnutrition diagnosis codes and enhancing nutritional practices to improve...
