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.

Exploring Chemistry Professors’ Methods of Highlighting the Relevancy of Chemistry: Opportunities, Obstacles, and Suggestions to Improve Students’ Motivation in Science Classrooms (open access)

Exploring Chemistry Professors’ Methods of Highlighting the Relevancy of Chemistry: Opportunities, Obstacles, and Suggestions to Improve Students’ Motivation in Science Classrooms

This article focuses on inquiring into undergraduate chemistry professors’ efforts in North America to increase student motivation and interest in the subject and the feasibility of methods that connect students to real world applications and societal issues related to chemistry. A survey was distributed to chemistry instructors at post-secondary institutions across the United States and Canada.
