Cracking the Copper Code
Turning carbon dioxide (CO2) into valuable chemicals, such as ethylene and ethanol, is a key goal in sustainable energy research, and a new study has uncovered critical insights into how copper-based catalysts can drive this transformation more efficiently. By combining surface-enhanced Raman spectroscopy (SERS) and computational modeling, the researchers identified the specific intermediates and active sites on copper surfaces that are responsible for converting CO2 into multi-carbon products – potentially leading to the design of more effective catalysts for industrial applications.
Using SERS, the team observed potential-dependent changes in the formation of CO dimerization and subsequent intermediates, providing real-time insights into the reaction process.

Empowering the Analytical Scientist in Everyone
In 2021, Michel Nielen, Aydogan Ozcan and Jeroen Jansen asked an important question: could the general public prove to be key in the next great phase of analytical chemistry?
“Enabling citizens to conduct their own measurements is of the utmost importance. In the 21st century, citizens are learning to gather and use their data in innovative ways,” said Jeroen Jansen, who has developed an SCiO Handheld NIR Spectrophotometer, which he uses away from the lab. “Whether it be maintaining health, improving their living environment, or examining exactly what their family is eating, citizens want to know more than ever before. The latest technological developments mean that citizens no longer have to rely on institutions for such measurements.”
