Nitrogen deprivation differentially alters lipid accumulation and pyrolysis-derived volatile profiles in three microalgal species

Nitrogen deprivation (N−) is widely used to induce lipid accumulation in microalgae. However, its impact on the relationship between lipid accumulation and thermochemical behavior remains poorly understood. In this study, a comparative experimental approach was used to evaluate t...

Mobile terahertz spectroscopy for in-situ evaluation of structural characteristics in wooden artefacts

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...
