A new approach to improve acoustic and UV-protection properties in blind curtains using recycled acrylic waste

Abstract This study aims to use acrylic fiber waste into a functional coating that enhances the acoustic and UV-protective properties of roller blind curtain fabrics, demonstrating a sustainable route for high-value textile waste utilization. Acrylic fibre waste was dissolved in...

Validation of a dynamic evaporation technique for generating isoflurane/air gas mixtures standards to calibrate anesthetic gas monitors

Abstract The dynamic evaporation and mixing technique standardized in EN 1839 (method T), originally developed to determine the flammability limits of chemical vapors, was applied to prepare isoflurane-in-air calibration gas mixtures, with air serving as the carrier gas. Isoflura...
