C&EN Uncovered: Looking back on 100 years of chemistry

Stereo Chemistry ·

2023/09/29

The first issue of C&EN was published in 1923 with the stated purpose of “the promotion of research, the development of the chemical industry, and the welfare of the chemist.” The world of chemistry has grown a lot since then, and the magazine has been there to report on it all. To celebrate our 100th anniversary, C&EN reporter and informal historian Alex Tullo has sifted through thousands of issues of the magazine, and in this episode, he guides our host Craig Bettenhausen on a tour through the

Early-career scientists are increasingly gravitating toward science policy, but the transition from the research bench to the policy office can be a tricky one. What can that path look like, and how can chemistry knowledge translate into a successful science policy career? In this bonus episode of C&EN’s Bonding Time, Mark Feuer DiTusa sits down with recent science PhD graduates and science policy professionals Jennifer DiStefano and Jared Mondschein to hear about their intertwined journeys, what

2023/08/11

Hydrogen might be the key to a clean energy future, but only if it can be made without fossil fuels. Most hydrogen today is made from methane. With generous government tax credits and enthusiasm for sustainable technology, the race is on for green hydrogen. Craig Bettenhausen, our usual host, guides C&EN associate editor Gina Vitale through the hydrogen rainbow and how the periodic table’s number 1 element could become the number 1 fuel.

Mining metals and minerals from seawater

Stereo Chemistry ·

2023/07/25

The modern world runs on electronic devices and energy systems that are powered by valuable elements such as lithium and uranium. There are a limited number of terrestrial mines that produce energy-critical elements, which makes the supply of these materials prone to disruption. So researchers are looking to an unconventional source: seawater. Almost every element on the periodic table can be found in global oceans–but most are dissolved in ultralow concentrations.

2023/07/07

Be they powered by fossil fuels, batteries, or hydrogen, cars are here to stay. So what can be done to make tires greener? In this episode of Stereo Chemistry, C&EN reporters Alex Scott and Craig Bettenhausen look at where the rubber meets the road, literally. Scott examined efforts to make tires more sustainable in a recent cover story for C&EN. He found people working on the movement and fate of tiny specks of tire-and-asphalt dust in the environment as well as large-scale efforts to shift to

When two wastewater treatment facilities in Baltimore, Maryland, broke down in early 2021, the surrounding waterways began filling up with sewage. In this episode of Stereo Chemistry, C&EN business reporter Craig Bettenhausen takes the pod to visit the Back River Plant and Patapsco Plant in the Chesapeake Bay watershed to demystify how these facilities treat wastewater and take a deep dive into the chemistry behind enhanced nutrient removal systems.

Carbon capture and sequestration is the trapping of CO2 emitted by industrial processes and depositing it beneath the Earth’s surface. Spurred on by tax credits offered by recent federal legislation, companies are racing to implement the technology in geologically suitable locations such as in Louisiana.However, the community around Lake Maurepas, Louisiana, has resisted efforts by Air Products to greenlight such a project under the lake.

2023/03/21

Lithium iron phosphate (LFP) batteries are cheaper, safer, and longer lasting than batteries made with nickel- and cobalt-based cathodes. In China, the streets are full of electric vehicles using this technology. But LFP never caught on as a chemistry for electric vehicle batteries in North America. In this episode, C&EN reporters Craig Bettenhausen and Matt Blois talk about the promise and risks of bringing lithium iron phosphate to a North American market.C&EN Uncovered, a new project from

2023/02/21

Researchers reported finding microplastics in drinking water nearly 5 years ago, prompting California lawmakers to require monitoring of the state’s drinking water for the tiny particles. But in 2018, there were no standard methods for analyzing microplastics. So California regulators reached out to chemists and toxicologists from all sectors to develop those methods. They also sought assistance in developing a health-based limit to help consumers understand what the monitoring results mean for

Replacing gas cars with electric ones is a main pillar of plans to fight climate change. But the lithium-ion batteries used in electric cars come with a cost. Communities near the Salar de Atacama in Chile, where about a quarter of the world’s lithium is extracted from salty aquifers, say mining companies pose a serious threat to the local environment and their access to water. Mining companies strongly dispute those claims. In this episode of Stereo Chemistry, we’ll explore the environmental

Chemists may know James Harris as the first Black scientist to be credited with codiscovering an element. In fact, we referenced this in a previous episode of Stereo Chemistry about making superheavy elements. But beyond this memorable factoid, details about the accomplished nuclear chemist are scarce, and most sources repeat the same superficial information. Kristen Frederick-Frost, curator of modern science at the Smithsonian’s National Museum of American History, wants to change that. After

Helium shortages can derail research and threaten expensive instruments that depend on the gas to operate safely. In late 2020, analysts predicted—and we reported—that pressures on the global helium market were likely to ease as new production capacity came online. Today, helium users are again facing price spikes and limited supplies, driven by a variety of factors including political instability in Europe and technical malfunctions at key suppliers.
