Cleaning archaeological bones: Influence of water, ethanol, and acetone on microhardness
نویسندگان
چکیده
The application of conservation treatments on archaeological bone is, in many cases, a necessary step for its study. Cleaning interventions can generate modifications the surface material or even modify elements variables involved this process have been scarcely characterized. present study reports characterization how different liquids commonly used cleaning processes contribute to onset by influencing microhardness. Three media were experimented with water, ethanol, and acetone. Knoop microhardness test was measure hardness samples from two sites: Gran Dolina localities at Barranc de la Boella, before during exposure liquids. Results note that all solvents produce decrease sample These variations should be considered when because they make it simpler damage tools.

Broadly tunable external cavity quantum cascade lasers (EC-QCLs) in combination with off-axis integrated cavity enhanced spectroscopy (OA-ICOS) provide high molecular gas sensitivity and selectivity. We used an EC-QCL in the region of 1150–1300 cm ́1 in both broadband scan mode, as well as narrow scanning mode around 1216 cm ́1, respectively, for detection of acetone in exhaled breath. This wavel...
