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. In this episode, C&EN reporters Craig Bettenhausen and Rick Mullin discuss the fears of the community around the implementation of carbon capture and sequestration around Lake Maurepas and the response from Air Products.C&EN Uncovered, a new project from C&EN's podcast, Stereo Chemistry, offers another look at subjects from recent cover stories.

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 C&EN's podcast, Stereo Chemistry, offers another look at subjects from recent cover stories.

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 their health. In this episode of Stereo Chemistry, we will hear from some of the scientists leading those groundbreaking efforts.

At Oak Ridge National Laboratory, a supercomputer named Frontier has broken the exascale computing barrier, meaning it can calculate more than a million trillion floating-point operations per second. In this episode, C&EN reporters Craig Bettenhausen and Ariana Remmel discuss how Frontier works and what that kind of power could mean for computational chemistry.C&EN Uncovered, a new project from C&EN's podcast, Stereo Chemistry, offers a deeper look at subjects from recent cover stories.

In this bonus episode of C&EN's Bonding Time, we hear from 2022 chemistry Nobel laureates Carolyn Bertozzi and K. Barry Sharpless, who shared the prize along with Morten Meldal for their work on click chemistry and bioorthogonal chemistry. After a November symposium honoring the US-based Nobel awardees at the Embassy of Sweden in Washington, DC, the two chemists discussed their long history of collaboration, how winning the 2022 Nobel Prize in Chemistry has changed their lives, and how they hope to use the spotlight to break down barriers within science.

The 2022 Nobel Prize in Chemistry was awarded to Carolyn Bertozzi, Morten Meldal and K. Barry Sharpless for their development of click and bioorthogonal chemistry which are used by chemists around the world to track biological processes and produce pharmaceuticals. In this special episode of Stereo Chemistry, hosts Gina Vitale and Ariana Remmel delve into the science behind the prize and talk with organic chemist Antoni Riera to discuss the applications of the award-winning chemistry. C&EN contributor Mark Peplow also joins the Stereo Chemistry crew to talk about his conversation with Nobel Laureate Carolyn Bertozzi.

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 factors at play in the salar and the differing perspectives on how best to measure impact. And we'll hear from a new group of mining start-ups that claim they can use chemical methods—as yet unproven—to extract lithium without the same impact on water.

This is the first episode in a new series exploring the future of water.

Famed lithium-ion-battery pioneer and Nobel Prize–winner John Goodenough has achieved yet another milestone—a century on Earth. Goodenough celebrates his 100th birthday on July 25, 2022. In honor of the occasion, Stereo Chemistry host Kerri Jansen and C&EN reporter Mitch Jacoby revisit their 2019 interview with the renowned scientist, recorded at his office at the University of Texas at Austin just prior to his Nobel win. In the expansive and candid conversation, Goodenough tells Stereo Chemistry about childhood adventures, infernal exams with Enrico Fermi, and his path to the innovation that enabled an electronics revolution.

This month, Stereo Chemistry is sharing an episode of the podcast ChemConvos featuring an interview with materials scientist, self-described "Raman spectroscopy enthusiast," and prolific Wikipedia editor Jess Wade. On ChemConvos, hosts Henry Powell-Davies and Medina Afandiyeva seek to uncover the story behind the scientist. In this episode, the trio discusses not only Jess's work as a research fellow at Imperial College London but also how she manages burnout and the importance of a supportive lab culture. And, of course, they dig into the origins of her Wikipedia project, which has resulted in Wade creating more than 1,400 biographies on Wikipedia aiming to highlight women, people of color, and LGBTQ+ scientists and engineers.

Our bodies need sugar to survive. But most of us consume way more than we actually need, and many foods and beverages pack a dose of added sweeteners. So why are we eating all of this extra sugar? This month, Stereo Chemistry is sharing an episode of the podcast Tiny Matters that examines that question. In the episode, hosts Sam Jones and Deboki Chakravarti explore sugar's impact on our bodies and trace how a genetic mutation that helped our distant ancestors survive is influencing our health today. And they dig into the debate around whether sugar can fairly be called addictive.

Note: This episode contains discussion of addiction and eating disorders.

ACS also publishes Chemical & Engineering News, which is the independent news outlet that powers Stereo Chemistry.
