2-(2-Hydroxyphenyl)-2H-benzotriazoles, also referred to as phenolic benzotriazoles, are an important class of UV absorbers [1] comprising the benzotriazole building block. Structure [ edit ]
Concentrations normally range from 0.05% to 2%, with some applications up to 5%. Frequently, glass can be a better alternative to polymers when it comes to UV degradation. Most of the commonly used glass types are highly resistant to UV radiation. Explosion protection lamps for oil rigs for example can be made either from polymer or glass. Here ...

They usually are catalysts. [1] They can function by many mechanisms, sometimes they donate an electron to the substrate, sometimes they abstract a hydrogen atom from the substrate. At the end of this process, the photosensitizer returns to its ground state , where it remains chemically intact, poised to absorb more light.
Each primary Kyuranger carries a Seiza Blaster (セイザブラスター, Seiza Burasutā, Constellation Blaster) gauntlet, which they can use to transform, access their Kyutamas' power, [2] [4] and perform the All-Star Crash (オールスタークラッシュ, Ōru Sutā Kurasshu), Kyuren All-Star Crash (キ ...
