After striving for six decades, HEP has developed into a major comprehensive publisher, with products in various forms and at different levels. Clipboard, Search History, and several other advanced features are temporarily unavailable. Bethesda, MD 20894, Web Policies However, due to the toxicity of hexavalent chromium, environmental and human health concerns have restrained their use and alternatives are being studied all over the world. KEYWORDS: self-healing coreshell nanofibers electrospinning Cited By This article is cited by 34 publications. The addition of UVP helps maintain the unique properties of the coating when subjected to long-term outdoor exposure, while preserving the underlying materials strength, coating adhesion, and appearance. Avoid prolonged or repeated breathing of vapor. Cadmium oxide films with and without silver-doping have been prepared by the SILAR method onto soda-lime-silica glass slides and characterized by scanning electron microscopy, UV-Visible spectroscopy and X-ray diffraction measurements. NANOMYTE MEND coatings can be healed multiple times at the same defect location, thereby reducing life cycle costs by increasing the service life and reducing maintenance costs of the various substrates to which it is applied. Zhang K, Yang W, Ge F, Xu B, Chen Y, Yin X, Liu Y, Zuo H. Int J Biol Macromol. Self The SHC coating possesses good photothermal property and can transform into liquid flow under sunlight to fill the defects.
