How do solar panels work? – in C&EN

The current energy crisis has re-energised conversations around the switch to renewable resources. Solar panels are one of the options, so in this month’s edition of Periodic Graphics in Chemical & Engineering News, we take a look at how these panels generate electricity and some of the present and potential materials used in them.

Nuclear waste and its disposal

Today (22 April) is Earth Day. While currently, we’re somewhat preoccupied with a different crisis, the climate crisis remains a pressing concern. Nuclear power is an oft-mentioned alternative to fossil fuels but comes with the associated problem of nuclear waste. Here, Matthew Harris explains some of the storage solutions and puts the problem in perspective.

Today in chemistry history: The Kyoto protocol

On this day back in 2005, the world’s first legally-binding climate change agreement came into force. The Kyoto protocol, to which 192 countries are a party, aimed to reduce emissions of six greenhouse gases by 5.2% by 2012, relative to 1990. This graphic gives a brief overview of the agreement and the outcome of its […]

The science of ice cores: Atmospheric time machines

We know what global temperatures are like now, from direct measurement around the globe. And we know quite a lot about what temperatures were like over the past few hundred years thanks to written records. But what about further back than that? How do we know what temperatures were like a thousand years ago, or […]
