To effectively utilize ultrasound, Collections it is crucial to identify materials and media that facilitate optimal penetration.Extraction and aluminum foil erosion experiments were performed using beakers made of glass, stainless steel, and various plastics (PE, PFA, and PTFE) under different ultrasonic conditions.Additionally, ultrasound-assiste
Whether for identification and characterization of materials or for monitoring of the environment, space-based hyperspectral instruments are very useful.Hyperspectral instruments measure several dozens up to hundreds of spectral bands.These data help to reconstruct the spectral properties like reflectance or emission of Earth surface or the absorpt
