The chemisorption of tert-butanol, an important product in atomic layer deposition (ALD) of ZrO 2 from the precursor, zirconium tetra-tert-butoxide, on Si(100)−(2×1), has been investigated using Auger electron spectroscopy (AES) and temperature-programmed desorption (TPD). The main desorption products of the TPD experiments are isobutene and molecular hydrogen. A comparison of TPD results...
Safe use of medical devices is a comprehensive concept with its technical integration. It includes not only its procedural operations but also its vigilance to patient status, correct installation of device, proper user's education and training, appropriate device maintenance, user facility compatibility, and acceptable interference from environment.
