Revealing the Quasi-Periodic Crystallographic Structure of Self-Assembled SnTiS3 Misfit Compound
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-28)Chemical vapor transport synthesis of SnTiS3 yields a self-assembled heterostructure of two distinct constituent materials, the semiconductor SnS and the semimetal TiS2. The misfit layer compound, although thermodynamically stable, is structurally complex, and precise understanding of the structure is necessary for designing nanoengineered heterojunction compound devices or for theoretical studies. ... -
A review of focused ion beam applications in optical fibers
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-02)Focused ion beam (FIB) technology has become a promising technique in micro- and nano-prototyping due to several advantages over its counterparts such as direct (maskless) processing, sub-10 nm feature size, and high reproducibility. Moreover, FIB machining can be effectively implemented on both conventional planar substrates and unconventional curved surfaces such as optical fibers, which are popular ... -
Setting-up an amplitude-modulation (AM) AFM for tapping mode
(Research report; Forskningsrapport, 2020)In this chapter, we are demonstrate how to set-up an amplitude-modulation (AM) AFM for tapping mode operation. We use a Cypher scanning probe microscope from Asylum Research. We employ our techniques for tip characterization and discuss the attractive and repulsive regimes. -
Should humans work?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-02-01)Should humans work? A simple question at a time when the advent of AI, automation and robotics claims a privileged position in the future of work. The question is perplexing and confusing however once we enquire into the meaning of technology and work as such: some claim that human jobs and well-being might be threatened by technological advances while others predict an increase in high skilled ... -
Simultaneous electrochemical determination of benzenediol compounds in environmental samples using nano architectures of hydrogen ammonium zinc molybdate layered double hydroxides integrated with carbon black modified electrode
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-02)Phenolic compounds, such as benzenediol (BD), are toxic and exhibit poor biodegradability, posing a threat to human health and the environment, even at low concentrations. Therefore, the simultaneous detection of BD at low detection limits and a wide detection range is of significant interest for monitoring water quality and environmental remediation efforts. In this study, we developed a novel ... -
Single-crystalline MoO<inf>3</inf>/functionalized multiwalled carbon nanotube nanocomposites for sensing phenothiazine in biological samples
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-03-21)The increasing use of pharmaceutical medications has significantly negative repercussions on the environment and human health. Here, a hydrothermal technique was employed to generate a single-crystalline molybdenum trioxide (MoO3)/functionalized multi-walled carbon nanotubes (MoO3/f-MWCNTs) nanocomposite that was then used as a novel electrode material for the electrochemical detection of phenothiazine ... -
Superposition of semiconductor and semi-metal properties of self-assembled 2D SnTiS3 heterostructures
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-15)Two-dimensional metal dichalcogenide/monochalcogenide thin flakes have attracted much attention owing to their remarkable electronic and electrochemical properties; however, chemical instability limits their applications. Chemical vapor transport (CVT)- synthesized SnTiS<sub>3</sub> thin flakes exhibit misfit heterojunction structure and are highly stable in ambient conditions, offering a ... -
Surface aging investigation by means of an AFM-based methodology and the evolution of conservative nanoscale interactions
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-07-05)The divergence in physical properties of surfaces exposed to airborne contaminants in the atmosphere has been widely investigated in recent years, but agreement regarding the role that airborne hydrocarbons and water contamination have on surface property evolution remains elusive. Here we investigate the evolution of a freshly grown highly oriented pyrolytic graphite (HOPG) surface exposed to a ... -
Surface etched carbon nanofiber companied ytterbium oxide for pinch level detection of fungicides carbendazim
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-11-26)The usage of a ytterbium oxide nanorod/carbon nanofiber (Yb<sub>2</sub>O<sub>3</sub>/f-CNF) hybrid nanocomposite for the electrochemical detection of carbendazim (CBZ) fungicide is demonstrated for the first time in this study. Various physicochemical methods such as Field Emission Scanning Electron Microscopy (FE-SEM), Transmission electron microscopy (TEM), and X-ray diffraction (XRD) spectroscopy ... -
Thickness-Dependent Resonant Raman and E' Photoluminescence Spectra of Indium Selenide and Indium Selenide/Graphene Heterostructures
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-05-28)Atomically thin, two-dimensional (2D) indium selenide (InSe) has attracted considerable attention because of the dependence of its bandgap on sample thickness, making it suitable for small-scale optoelectronic device applications. In this work, by the use of Raman spectroscopy with three different laser wavelengths, including 488, 532, and 633 nm, representing resonant, near-resonant, and conventional ... -
Ultra-Cheap Renewable Energy as an Enabling Technology for Deep Industrial Decarbonization via Capture and Utilization of Process CO2 Emissions
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-07-17)Rapidly declining costs of renewable energy technologies have made solar and wind the cheapest sources of energy in many parts of the world. This has been seen primarily as enabling the rapid decarbonization of the electricity sector, but low-cost, low-carbon energy can have a great secondary impact by reducing the costs of energy-intensive decarbonization efforts in other areas. In this study, ... -
Uncovering Contributing Factors to Interruptions in the Power Grid: An Arctic Case
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-01-03)Electric failures are a problem for customers and grid operators. Identifying causes and localizing the source of failures in the grid is critical. Here, we focus on a specific power grid in the Arctic region of Northern Norway. First, we collected data pertaining to the grid topology, the topography of the area, the historical meteorological data, and the historical energy consumption/production data. ... -
What is going on with Middle Eastern solar prices, and what does it mean for the rest of us?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-04)For the third time in a decade, solar energy pricing records are tumbling in the Persian Gulf. As each previous wave of new records was met with incredulity, only for these prices to become the new normal around the world within a few years, it would be unwise to once again dismiss low prices as unrepresentative outliers. In this study, we show how local conditions and global macroeconomic factors ...
