Dermed fjernes ikke spesifikke forurensninger, forklarer materialforsker Patricia Carvalho i SINTEF. – Vi har manglet effektive, selektive og bærekraftige sorbenter, og dypingitt viser svært lovende sorpsjonsegenskaper. Patricia Carvalho i SINTEF ser på dypingitt med transmisjonselektronmikroskopet på...
The majority of nanomaterials (NMs) used in industrial and commercial applications are likely to enter the wastewater stream and reach wastewater treatment plants (WWTPs). In Oslo, Norway, the WWTPs receive both municipal and industrial wastewater. The treated effluents are discharged to aquatic...
Background The effects of stress on surgical residents and how stress management training can prepare residents to effectively manage stressful situations is a relevant topic. This systematic review aimed to analyze the literature regarding (1) the current stress monitoring tools and their use in...
Objective Currently available cytotoxic treatments have limited effect on pancreatic ductal adenocarcinoma (PDAC) because desmoplastic stroma limits drug delivery. Efforts have been made to overcome these barriers by drug targeting the tumor microenvironment. Results so far are promising, but...
In seasonal ice zones (SIZs), such as the one of the Greenland Sea, the sea ice growth in winter and subsequent melting in summer influence the phytoplankton activity. However, studies assessing phytoplankton activities over complete annual cycles and at a fine temporal resolution are lacking in...
In recent years, high-performance multicrystalline silicon (HPMC-Si) has emerged as an attractive alternative to traditional ingot-based multicrystalline silicon (mc-Si), with a similar cost structure but improved cell performance. Herein, we evaluate the gettering response of traditional mc-Si and...
High-entropy alloys (HEAs) represent a class of materials that is intensively investigated for a range of possible applications. They generally show a high degree of phase stability by the high entropy while the structure is a random atom position disorder unlike other alloys which can influence...
Oxide containing films were deposited by reactive sputtering using a high entropy alloy (HEA) target made of equal concentrations of the five 3d-transion metals: Cr, Fe, Co, Ni, and Cu. We report on controlled alterations to the electrical properties made by post-deposition heat treatments in...
In this work we present a significant advancement in cubic silicon carbide (3C-SiC) growth in terms of crystal quality and domain size, and indicate its potential use in photovoltaics. To date, the use of 3C-SiC for photovoltaics has not been considered due to the band gap of 2.3 eV being too large...
Introduction/Purpose Reversible diffusionless first-order phase transformations are a fundamental part of phase change materials and shape memory alloys [1]. Some of these materials even possess useful physical characteristics that show abrupt changes e.g. in their electrical[2] and magnetic...
Photovoltaic (PV) systems are widely used globally to decarbonize building energy systems. However, economic and social challenges hinder broader deployment, raising concerns about the viability of this technology. This study explores the key factors influencing the economic profitability of PV...
The decarbonisation of the construction sector is critical to meet national and international climate goals. Literature gives many examples of measures for the reduction of greenhouse gas (GHG) emissions from buildings. However, few studies investigate the tradeoffs between potentially conflicting...
Plastic pollution poses urgent environmental, societal, and health challenges, yet governance remains fragmented. The 2022 UNEA resolution 5/14 offers an opportunity for a legally binding treaty, but negotiations are stalled by geopolitical tensions, entrenched industrial interests, and divergent...
The availability of analytical methods for the characterization of lipid nanoparticles (LNPs) for in-vivo intracellular delivery of nucleic acids is critical for the fast development of innovative RNA therapies. In this study, analytical protocols to measure (i) chemical composition, (ii) drug...
Introduction: Effectiveness of e-learning diminishes without the support of a pedagogical model to guide its use. In minimally invasive surgery (MIS), this has been reported as a limitation when technology is used to deliver contents without a sound pedagogical background. Material and methods...
...characterization of microscopic and functional properties of multiferroic PTMs. bilde The project partners are: SINTEF, Materials Physics, Ole M. Løvvik, Patricia A. Carvalho, Øystein Dahl, Spyros Diplas, Marit Stange: First-principles calculations, high-throughput experimental synthesis, functional property...
An early dialogue between nanomedicine developers and regulatory authorities are of utmost importance to anticipate quality and safety requirements for these innovative health products. In order to stimulate interactions between the various communities involved in a translation of nanomedicines to...
Objective: The rise in metabolic dysfunction–associated steatotic liver disease prevalence, closely linked with metabolic syndromes and obesity, demands accurate, cost-effective diagnostic methods for early-stage fat quantification in the liver. Here we demonstrate a novel dual-frequency ultrasound...
Headlines in December 2024 proclaimed the “collapse” and “failure” of United Nations plastics treaty negotiations in Busan, South Korea. This is, however, an overly simplistic and pessimistic portrayal. Progress on less contentious issues was made, and the meeting was adjourned with a commitment to...
Planning and building for future disassembly and the reuse of materials have been identified as promising design strategies for the implementation of circular economy principles in the construction sector. These strategies are expected to contribute to reducing material related greenhouse gas (GHG...
