In situ detection of an unstable C,N-Au(III) chelate by 15N NMR methods
(Peer reviewed; Journal article, 2022)Au(III)-NHC-oxazolyl complexes are prepared by oxidation and anion exchange of the corresponding Au(I)Cl-NHC-oxazolyl precursors, which are synthesized from appropriate imidazolium pre-ligands. As the Au(III) complexes are ... -
In situ DSC investigation into the kinetics and microstructure of dispersoid formation in Al-Mn-Fe-Si(-Mg) alloys
(Journal article; Peer reviewed, 2018)Dispersoid strengthening in Al-Mn-Fe-Si(-Mg) aluminum wrought alloys can play an important role in applications at elevated temperatures. Fine and evenly distributed dispersoids are needed to increase alloy strength, which ... -
In situ evaluation of a timber structure using a drilling resistance device. Case study: Kjøpmannsgata 27, Trondheim (Norway)
(Journal article; Peer reviewed, 2017)The aim of this study was to evaluate the structural health of a 19th-century warehouse located in Trondheim using a drilling resistance device. The building, Kjøpmannsgata 27, is one of the many bryggene which are situated ... -
In situ evidence of earthquakes near the crust mantle boundary initiated by mantle co2 fluxing and reaction-driven strain softening
(Journal article; Peer reviewed, 2019)This study aims to understand the process behind the worldwide connection between deep crustal/upper mantle earthquakes and CO2 emissions along faults in rift zones. We do this by studying CO2-induced mineral reactions ... -
In situ hard X-ray transmission microscopy for material science
(Journal article; Peer reviewed, 2017)Hard X-ray transmission microscopy based on refractive X-ray optics can be employed as a tool in material science to investigate buried-in microstructures in two or three dimensions with spatial resolution approaching 100 ... -
In situ heating TEM observations of evolving nanoscale Al‐Mg‐Si‐Cu precipitates
(Journal article; Peer reviewed, 2019)This research concerns the precipitation and subsequent dissolution of precipitate phases in an Al–0.86Mg–0.62Si–0.1Cu (at.%) alloy subjected to varying thermal exposure during an in situ heating transmission electron ... -
In situ high temperature spectroscopic study of liquid inclusions and hydroxyl groups in high purity natural quartz
(Peer reviewed; Journal article, 2021)High purity natural based quartz is used as raw material for production of crucibles for solar-grade silicon production. The crucible properties are strongly related to presence of water and hydroxyl groups in the raw ... -
In Situ Improvement of Highly Sensitive Clays by Potassium Chloride Migration
(Journal article; Peer reviewed, 2017)Highly sensitive, low-saline clays, termed quick clays, represent a risk for large landslides. An in situ experiment was conducted in which salt wells filled with potassium chloride were installed to study how salt wells ... -
In situ investigation of spinodal decomposition in hypermonotectic Al–Bi and Al–Bi–Zn alloys
(Journal article; Peer reviewed, 2008)Spinodal decomposition of hypermonotectic Al–6 wt.%Bi, Al–8 wt.%Bi and Al–6 wt.%Bi–8 wt.%Zn alloys has been investigated using synchrotron radiography. In the case of the 6 and 8 wt.%Bi binary alloys undercoolings of ... -
In Situ Measurements of the Chemical Stability of a Cast Aluminum Alloy Embedded in a Cement Paste with a High Amount of Supplementary Cementitious Material
(Peer reviewed; Journal article, 2021)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 ... -
In situ micromechanical testing in environmental scanning electron microscope: A new insight into hydrogen-assisted cracking
(Journal article; Peer reviewed, 2018)The susceptibility of Fe–26Al–0.5Cr (at.%) intermetallic alloy to hydrogen assisted cracking was evaluated by micromechanical fracture mechanics specimens. The notched micro-beams were loaded in situ in an environmental ... -
In situ monitoring of pit gas composition during baking of anodes for aluminum electrolysis
(Journal article; Peer reviewed, 2019)Carbon anodes, which are consumed in aluminum electrolysis, are fabricated in separate anode plants where coke and pitch are mixed and vibrocompacted to green anode blocks before being baked in anode baking furnaces. The ... -
In situ observation of the carbothermic reduction and foaming of slags in silicomanganese production
(Journal article; Peer reviewed, 2021)The carbothermic reduction of slag in silicomanganese production is accompanied by the release of carbon monoxide. This gas can accumulate as bubbles within the slag, leading to foaming and, potentially, disturbances to ... -
In situ recordings of large gelatinous spheres from NE Atlantic, and the first genetic confirmation of egg mass of Illex coindetii (Vérany, 1839) (Cephalopoda, Mollusca)
