Photochemical reactions and on-line UV detection in .

The design of reactor chip II was motivated by the integration of the reaction and detection units, and was intended to accommodate reactions that require light of deeper UV (e.g. many photochemical reactions require 254 nm light). Pyrex wafers absorb too strongly at these wavelengths to be suitable.

What is Photochemical Smog? Formation and Causes with FAQs

What is Photochemical Smog? Formation and Causes with FAQs

Photochemical smog, also known as summer smog, is a type of smog that is produced when UV light originating from the sun interacts with the oxides of nitrogen present in the atmosphere. This type of smog usually manifests as a brown haze and is most commonly seen in highly populated cities that are placed in relatively warm climates.
