An experimental study has been performed on the interrelationship between visual appearance, surface topography and light scattering on AA6063-T6 aluminium extrusions etched to a depth of up to 700 μm. The topography was characterized by use of White Light Interferometry (WLI), and light scattering...

Use of photovoltaics (PV) is key remedies in buildings where a large part of the energy supply should be based on renewable energy. PV in Nordic climate can be challenging because ofand temperatures below zero. The aim of this research work has been to provide a state-of-the art overview of recent...

Sulfur-containing materials may be of importance in devices such as proton conducting fuel cells for energy conversion involving fossil or bioderived fuels. First-principles calculations were employed to elucidate the thermodynamics of proton incorporation as well as proton migration barriers in...

The effect of elevated temperature during storage and curing of ultra-high performance concrete (UHPC) formulated aerogel-incorporated mortar (AIM) samples was investigated. It was found that an effective aerogel loading of 60 vol% of total bulk volume was possible for producing AIM samples with...

Droplet erosion protection coatings has been proposed, tested and compared with industrial solutions. All of the proposed coatings are based on a PU matrix, which is shown to provide good damping effects and good erosion resistant properties. Two of the coating was reinforced with particles to...

This work investigates the metallurgical changes occurring during welding of clad pipes. Welded samples with and without a Ni-interlayer between the clad and base metal (BM) were investigated by light optical microscope, electron microprobe analysis and microhardness measurements. The...
