From traditional to technical: using laser Doppler vibrometry to preserve frescoes
U.S. Capitol fresco detection color map. Lighter colors indicate greater vibrations in the plaster and therefore delamination. Credit: Nick Ganemi Fresco is an ancient technique in which dry pigments are applied to wet plaster to create stunning works of art that can be preserved for centuries. However, over time, these masterpieces often face deterioration due to delamination, where the decorative…

Laser vibration sensing technology can detect landmines faster than traditional techniques
Researchers at the National Center for Physical Acoustics are developing a faster and more efficient way to detect buried objects such as landmines using laser arrays and vibrating machines. In this image, objects buried in the soil appear as red blobs. NCPA Chief Scientist Vyacheslav Aranchyk (right) recently introduced the technology at a conference in Japan.

Chemists challenge traditional views on crystal growth
Graphical summary. Credit: Matter (2024). DOI: 10.1016/j.matt.2024.08.011 Remember the old high school chemistry experiment where salt crystals precipitate from a salt solution, or rock candy crystals form from sugar water? Learn about how crystals form in these solutions It turns out that your understanding of may be wrong. A new theory elucidates the crystallization process and shows that the substance…
