Ecotoxicological impacts of surface water and wastewater from conventional and advanced treatment technologies on brood size, larval length, and cytochrome P450 (35A3) expression in Caenorhabditis elegans
(Journal article; Peer reviewed, 2018)Anthropogenic micropollutants and transformation products (TPs) negatively affect aquatic ecosystems and water resources. Wastewater treatment plants (WWTP) represent major point sources for (micro)pollutants and TPs in ... -
Edge functionalization of finite graphene nanoribbon superlattices
(Journal article; Peer reviewed, 2019)The effect of chemical functionalization on the electronic properties of graphene nanoribbon superlattices with zigzag and armchair terminations is investigated using the density functional theory. The calculated positive ... -
Edge interfaces of the Ω plates in a peak-aged Al-Cu-Mg-Ag alloy
(Journal article; Peer reviewed, 2022)The coherent edge interface structures of the relatively thin {111}Al Ω plates have been analyzed in a peak-aged Al-Cu-Mg-Ag alloy by atomic-resolution scanning transmission electron microscopy (STEM). Analysis of STEM ... -
Edge-modified zigzag-shaped graphene nanoribbons: structure and electronic properties
(Journal article; Peer reviewed, 2014)Control of the band gap of graphene nanoribbons is an important problem for the fabrication of effective radiation detectors and transducers operating in different frequency ranges. The periodic edge-modified zigzag-shaped ... -
Edge/basal/defect ratios in graphite and their influence on the thermal stability of lithium ion batteries
(Journal article, 2016)Raw graphite can be processed industrially in large quanta but for the graphite to be useful in lithium ion batteries (LIB's) certain parameters needs to be optimized. Some key parameters are graphite morphology, active ... -
eDNA metodetesting av makroorganismer i marine habitater
(Bachelor thesis, 2023)Framkomsten av eDNA-studier har vist seg å være en lovende metode for å utforske og forstå biologisk mangfold, spesielt innenfor marine miljøer som tradisjonelt har brukt inntrengende metoder for overvåkning av biodiversitet. ... -
Educational inequalities in adult mortality: a systematic review and meta-analysis of the Asia Pacific region
