Analysis of Thermohydraulic Spalling in Blended Cement Concrete
Abstract Recently, the construction industry has increasingly focused on the development of more sustainable transport infrastructure, such as tunnels, driven by the growing use of clinker-reduced cements. One major challenge in this context is fire exposure, which can lead to se...

Development and analysis of a mixed colloid standard with trace elements using AF4-ICP-MS
Environmental context Colloids are small, unstable particles that play important environmental roles in the transport of trace elements and can be analysed using asymmetrical flow field-flow fractionation (AF4) coupled to inductively coupled plasma–mass spectrometry (ICP-MS). A m...

Abstract Bioimaging, sensing, and photonic applications of oxygen-sensitive luminophores such as near-infrared (NIR) emissive spin-flip complexes of earth-abundant chromium (CrIII) and triplet metal-to-ligand charge transfer complexes like ruthenium (RuII), osmium (OsII) or iridi...

Transmission diffuse EUV scattering by nanoscale Lamb waves in thin membranes
We report time-resolved diffuse extreme ultraviolet (EUV) scattering measurements of optically excited acoustic waves in thin Ti/SiN bilayers in transmission geometry. Following femtosecond optical excitation, the EUV diffuse scattering signal yields circular fringe patterns evol...

Abstract Conserving fragile wooden artworks requires diagnostics that detect minimal structural changes without invasive intervention. We used a robotic-arm terahertz time-domain spectroscopy (THz TDS) system to study the centrepiece of the Marienaltar in Isenhagen Monastery (Han...

Abstract Additive manufacturing by DED-Arc enables the production of large and complex high-strength steel components. However, the residual stress state generated during deposition can be significantly altered when the component is separated from the substrate plate as a final m...
