Your fancy white electronic brick of consumer electronics started off white, but after some time it yellowed and became brittle. This shouldn’t have happened; plastic is supposed to last forever. It ...

Photochemical reactions begin by absorption of energy in the form of light, and involve formation of free radicals and transient excited states whose physical and chemical properties are very ...

Photodegradation in aqueous environments is a crucial natural attenuation process that facilitates the breakdown of pesticides into simpler compounds or transformation products (TPs). This complex ...

Why does plastic turn brittle and paint fade when exposed to the sun for long periods? Scientists have long known that such organic photodegradation occurs due to the sun’s energy generating free ...

Mark Tibbitt demonstrates differences in photodegradation between step- and chain-growth hydrogels based on fundamental polymer physics theory. M.W. Tibbitt, A.M. Kloxin, and K.S. Anseth, "Modeling ...
