Atlanta may not be the first city that comes to mind when you think of sustainability — but perhaps, it should be.
Halide perovskite solar cells have in recent years emerged as a potential alternative to silicon-based photovoltaics due to their outstanding performance, having reached energy conversion efficiency comparable to the currently available silicon counterparts in less than a decade of research. Therefore, in addition to vast academic interest, industries are paying close attention to the development of perovskite-based photovoltaics.
Plastic bag bans are the subject of discussion in state and local governments across America as people struggle with how to respond to the scourge of plastic waste.
What started as a 10-year-old child’s persistence has become a career for Elisabeth Pesavento ’21. “I told my mom that I really wanted to play the horn,” Pesavento said. “And you know, like all mothers, she’s said, ‘Oh that’s nice. It’s a very beautiful instrument.’ But I just kept asking and kept asking until finally she was like, ‘Wow, I guess she really does want to play the horn.’” After Pesavento finally got her French horn, she traveled the world with the instrument.
We have all seen images or read the worrying reports: plastic rubbish is piling up in our oceans and littering our beaches. Animals get caught in ghost nets, and micro plastics enter our food chain. But it doesn’t have to be that way. Whilst the key to fighting marine litter is to stop it at the source – using less, recycling more – cleaning matters as well. Together, we can turn a drop in the ocean into a wave of change.
