Infrared spectroscopy with machine learning detects early wood coating degradation
Improve the sustainability of wooden buildings. Credit: (Kyoto/Whitney Havel) From Japanese cypress to ponderosa pine, wood has been used in construction for thousands of years. Materials such as steel and concrete have taken over the construction of large-scale buildings, but timber has been revived and is increasingly being used in public and multiple buildings due to environmental benefits. Of course,…

Scientists discover better when it comes to time domain spectroscopy of terahertz
A close-up of a simplified experimental setup of Terahertz Time-Domain spectroscopy, demonstrated by Hayazawa and his team. Credit: Riken Advanced Photonics Center A simple adjustment to a normal setup is all that is needed to enhance spectroscopic techniques using waves in the terahertz region for samples, Riken physicists discovered. Findings can be found in the Journal Applied Physics Letters. Developing…

Order of obstacles: Scientists take a closer look at ice-like surfaces with spectroscopy, simulation and machine learning
Graphical abstract. Credit: Jacs Au (2025). doi: 10.1021/jacsau.4c00957 Ice can speed up molecule adsorption or stickiness, just as the tongue freezes to a frozen metal pole. The surface of ice can break down molecules in the presence of light and release trace gases. Before researchers can measure these responses and incorporate their effects into global atmospheric models, researchers must first…

Photoacoustic spectroscopy approach enables real-time detection of low gas concentrations
A new method for detecting and identifying gases at very low concentrations in real time adds coherent control to quartz-enhanced photoacoustic spectroscopy, which uses a quartz tuning fork to detect gas absorption. Credit: Florian Sterl, Sterltech Optics GmbH Researchers have developed a new method to quickly detect and identify gases at very low concentrations. This new approach, called coherently controlled…

High-resolution IR spectroscopy reveals new insights into hydrogen bonding in hydrogen sulfide
Far-infrared spectrum of H2S-H2S at T = 0.37 K calculated using ab initio intermolecular potentials and dipole functions. Credit: Nature Communications (2024). DOI: 10.1038/s41467-024-53444-6 At first glance, water and the foul-smelling molecule hydrogen sulfide don’t seem to have much in common. However, if you invest a little energy, some differences will disappear. At first glance, the smell of soft drink…
