Electro active repair of concrete demonstration of applicability
(Chapter, 2017)Conventional concrete patch repairs have poor durability: 50% fail within ten years. A major cause is insufficient removal of contaminated concrete and insufficient steel cleaning. Chlorides left behind reactivate the ... -
Electro-absorption of silicene and bilayer graphene quantum dots
(Journal article; Peer reviewed, 2016)We study numerically the optical properties of low-buckled silicene and AB-stacked bilayer graphene quantum dots subjected to an external electric field, which is normal to their surface. Within the tight-binding model, ... -
Electro-hydrodynamic propulsion of counter-rotating Pickering drops
(Journal article; Peer reviewed, 2016)Insulating particles or drops suspended in carrier liquids may start to rotate with a constant frequency when subjected to a uniform DC electric field. This is known as the Quincke rotation electro-hydrodynamic instability. ... -
Electro-optical properties of phoshorene quantum dots
(Journal article; Peer reviewed, 2017)We study electronic and optical properties of single layer phosphorene quantum dots with various shapes, sizes, and edge types (including disordered edges) subjected to an external electric field normal to the structure ... -
Electro-oxidation of ethanol at Pt electrodes with the use of a Dynamic Electrochemical Impedance Spectroscopy (DEIS) technique
(Master thesis, 2012)Electro-oxidation of ethanol on smooth platinum surfaces was studied in thetemperature range 21C to 140C for 0.2 M ethanol in 0.5 M sulphuric acid.This was done by use of cyclic voltammetry and electrochemical impedances ... -
Electro-oxidation of small organic molecules
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:348, Doctoral thesis, 2012)An alternative to fossil fuels is to utilize biofuels like methanol and ethanol directly in fuel cells. One drawback of this system is the sluggish reaction kinetics in methanol and ethanol oxidation where strongly bound ... -
