Ionic Liquids as Additives in Low Viscosity Lubricants – A Surface Adsorption and Tribofilm Study
(Doctoral theses at NTNU;2022:130, Doctoral thesis, 2022)The trend in lubrication nowadays is towards low viscosity lubricants. Low viscosity lubricants flow more easily, increasing the lubricant volume circulation thus improving the cooling performance and cleaning ability of ... -
Ionic Liquids as Additives in Water‑Based Lubricants: From Surface Adsorption to Tribofilm Formation
(Peer reviewed; Journal article, 2020)Ionic liquids (ILs) are potential lubricant additives that can potentially perform simultaneously as friction modifiers and anti-wear agents. In addition, they possess good thermal stability, they are non-flammable, they ... -
Ionic liquids as boundary additives in water-based and PAO lubricants
(Peer reviewed; Journal article, 2021)Ionic liquids have been widely discussed as potential lubricants, however, their properties make them also very good potential candidates as lubricant additives (e.g., friction modifiers and anti-wear). In this work, the ... -
IPD governance implications
(Chapter, 2019)Interest in project-management (PM) governance has grown steadily over the past decade. Turner (2006) introduced, over a decade ago, the role of governance (based on a definition of corporate governance) in the development ... -
