Effect of crucible rotation on the temperature and oxygen distributions in Czochralski grown silicon for photovoltaic applications
(Peer reviewed; Journal article, 2021)Temperature and oxygen distributions were numerically studied for the Czochralski (Cz) growth of 8′′ diameter silicon single crystals for photovoltaic applications. Fluctuations in the dopant concentration (striation ... -
The effect of Cu and Ge additions on strength and precipitation in a lean 6xxx aluminium alloy
(Peer reviewed; Journal article, 2015)It has been demonstrated that the strength loss in a lean Al-Mg-Si alloy due to solute reduction could be compensated by back-adding a lower at % of Ge and Cu. Nanosized precipitate needles which are the main cause of ... -
Effect of cyclic ageing on the early-stage clustering in Al–Zn-Mg(-Cu) alloys
(Peer reviewed; Journal article, 2022)The cyclic application of mechanical stress to aluminum alloys at room temperature, referred to as cyclic ageing, continuously injects vacancies, enabling dynamic precipitation of a fine distribution of solute clusters. ... -
Effect of demand-controlled ventilation strategies on indoor air pollutants in a classroom: A Norwegian case study
(Peer reviewed; Journal article, 2023)The choice of the minimum ventilation rate (Vmin) in a demand-controlled ventilation strategy can influence energy demand but also introduce outdoor air pollutants. The latter may have direct health effects, as well as ... -
Effect of different SiO2 polymorphs on the reaction between SiO2 and SiC in Si production
(Peer reviewed; Journal article, 2021)This work investigates the phase transformations in silica (SiO2) during heating to a target temperature between 1700 °C and 1900 °C and the effect of SiO2 polymorphs on the reduction reaction 2SiO2 + SiC = 3SiO + CO in ... -
Effect of electric field on push-out strength of cemented steel pipes
(Peer reviewed; Journal article, 2021)Cement-steel interfacial strength is an important measure for estimating the robustness and hydraulic sealing ability of wells. In this paper, laboratory experiments were performed in which small steel pipes (10 mm in ... -
Effect of Elevated Hydrogen Partial Pressure on Mixed Culture Homoacetogenesis
(Peer reviewed; Journal article, 2021)This study aimed to systematically investigate the effect of elevated hydrogen partial pressure on mixed culture homoacetogenesis in the range of 1–25 bar. Seven batch experiments were performed at different initial headspace ... -
The Effect of Feeding Strategy on Butanol Production by Clostridium beijerinckii NCIMB 8052 Using Glucose and Xylose
(Peer reviewed; Journal article, 2018)We performed fed-batch fermentations of glucose and xylose mixtures producing butanol. Our aim was to develop a feeding strategy for coping with carbon catabolite repression (CCR) and sequential utilization problems as ... -
