Zhang, X. (author), Noel-Hermes, N. (author), Ferrari, G. (author), Hoogeland, M.G. (author)Corrosion of mooring chains is regarded as one of main threats to the offshore mooring systems. Localized corrosion is even more dangerous than uniform corrosion because it may not show significant mass loss but it can cause stress concentration and initiate cracks under force, leading to accelerated degradation of mooring chains. Localized...article 2022

(author)We report on advanced defect classification using TNO's RapidNano particle scanner. RapidNano was originally designed for defect detection on blank substrates. In detection-mode, the RapidNano signal from nine azimuth angles is added for sensitivity. In review-mode signals from individual angles are analyzed to derive additional defect...conference paper 2018

(author)Cement based mortars are widely used as adhesive for tiles in building and construction. They have a limited timespan during which a tile can be placed effectively in order to develop sufficient bond strength. This timespan, usually called ’open time’, is controlled, amongst others, by adding water soluble polymers such as methyl cellulose or...conference paper 2015
