On June 12, 2019, the US Environmental Protection Agency (US EPA) announced its seven enforcement and compliance assurance priority areas for fiscal years 2020-2023. One of the National Compliance Initiatives includes “Stopping Aftermarket Defeat Devices for Vehicles and Engines.” Specifically, the Agency expressed that it will have a focus on reducing aftermarket defeat device manufacture, sale, and installation across vehicle types.
When you watch a local television weather forecast Friday, look closely. You might spot your hometown meteorologist showing his or her stripes.
Some weather presenters don ties or earrings, a pattern of red-and-blue stripes draped across the articles. Others might project an image of the corresponding stripe array behind them via a monitor or green screen, the colorful assortment of lines resembling a tie-dyed bar code. And in a sense, each collection of stripes is a sort of bar code, containing vitally important information: climate information.
The simple graphics — originally created by climate scientist Ed Hawkins — leave a striking visual impression. In general, the bars transition from cool deep blues and azures on the left to warm yellows, oranges and even reds on the right. Each vertical stripe represents a year, its color corresponding to temperature anomalies. It’s an easily accessible way to convey an alarming trend.
New insights about how to understand and ultimately control the chemistry of ignition behavior and pollutant formation have been discovered in research led by Sandia. The discovery eventually will lead to cleaner, more efficient internal combustion engines.
“Our findings will allow the design of new fuels and improved combustion strategies,” said Nils Hansen, Sandia researcher and lead author of the research. “Making combustion cleaner and more efficient will have a huge impact, reducing energy use around the globe.”
The work, which focuses on the chemical science of low-pressure flame measurements, is featured in the Proceedings of the Combustion Institute and was selected as a distinguished paper in Reaction Kinetics for the 37th International Symposium on Combustion. Authors include Nils, Xiaoyu He, former Sandia intern Rachel Griggs and former Sandia postdoctoral fellow Kai Moshammer, who is now at the Physikalisch-Technische Bundesanstalt in Germany. The research was funded by the DOE’s Office of Science.
The state Department of Justice has lined up six nationally known law firms to represent New Hampshire in its landmark lawsuit against major chemical companies over contamination from chemicals used in products with trade names like Teflon and Scotchgard.
Corals can help scientists track ancient climate patterns, but new research suggests that traditional analysis methods for analyzing coral’s ancient growth aren’t as accurate as previously thought.
Luckily, scientists have developed an improved method, a combination of high-resolution microscopic analysis and geochemical modeling. Researchers described the new technique this week in the journal Frontiers in Marine Science.
Innovators are being invited to enter a Circular Economy Challenge, one of MIT’s “Solve” initiatives, as part of a growing push towards products that generate zero waste with minimal environmental impact.
