Effects of UV Stabilizers on Polypropylene Outdoors

This article looks at hindered amine light stabilizers (HALSs) and nano ZnO were used to stabilize polypropylene (PP) film-based formulations that were exposed to ultraviolet (UV) light for different lengths of time, simulating the harsh outdoor weather of Dallas, Texas, USA. UV doses applied in our laboratory are 121 times larger than the UV dose provided by the sunlight in Texas. 15 different compositions were studied. The combination of HALSs and nano-ZnO stabilizers makes the PP films harder—which is important for some PP applications, such as toy manufacturing.

Preferential intracellular pH regulation is a common trait amongst fishes exposed to high environmental CO2 (open access)

Preferential intracellular pH regulation is a common trait amongst fishes exposed to high environmental CO2

Article testing the hypothesis that preferential pHi regulation is a widespread strategy of acid–base regulation among fish by measuring pHi regulation in 10 different fish species that are broadly phylogenetically separated, spanning six orders, eight families and 10 genera.
