Great Lakes Climate Modeling in the News

image98360-persPengfei Xue (CEE) and his modeling work through the Great Lakes Research Center, which led to a more comprehensive climate and hydrodynamics model for the whole Great Lakes region, has been featured in several science media outlets including Science Daily, Phys.org, Terra Daily and Supercomputing Online News. The story was shared numerous times by collaborators and the science community on Twitter.

Weather the Storm: Improving Great Lakes Modeling

The collaborative work brought together researchers from Michigan Technological University, Loyola Marymount University, LimnoTech and the National Oceanic and Atmospheric Administration’s Great Lakes Environmental Research Laboratory. Pengfei Xue, an assistant professor of civil and environmental engineering at Michigan Tech, led the study through his work at the Great Lakes Research Center on campus.

One of the important concepts in climate change, in addition to knowing the warming trend, is understanding that extreme events become more severe. That is both a challenge and an important focus in regional climate modeling. —Pengfei Xue

Jaszczak Leads Discovery of New Mineral

image144299-persA team led by a physicist from Michigan Tech has discovered a new mineral, named for the region in Tanzania where it comes from.

John Jaszczak knew that something was very unusual about the mineral specimen he was examining under the microscope of a Raman spectrometer in the basement of Fisher Hall.

On a hunch, Jaszczak decided to look into it further. The diagnostic studies with Raman spectrometry and scanning electron microscopy showed a layered structure rich in molybdenum, lead and sulfur that may be a new mineral. Now, Jaszczak and the team he pulled together can confirm that gut feeling. The tiny, silvery, cylindrical whiskers are indeed a new mineral—merelaniite. The journal Minerals published the team’s findings last week.

Detailed chemical and physical analyses of merelaniite—a member of the cylindrite group—revealed a neatly stacked layered structure with sheets rolled in scrolls like tobacco in a cigar. These tiny whiskers, which to the naked eye look like very fine hairs on other larger crystals, have probably been regularly cleaned off their host rocks containing other more recognizable minerals that occur at the famous gem mines near Merelani, Tanzania.

But it doesn’t negate the value of less showy minerals.

Lynn Mazzoleni Leads a Team to Bring a New High-Resolution Spectrometer to Campus

PicoAir is not just air. It’s not just a sterile, preset mix of oxygen, hydrogen, carbon dioxide and other molecules. As an atmospheric chemist, Lynn Mazzoleni knows air is dynamic and full of soot, sulfates, dust and other particles. Now, with a new piece of equipment, she can analyze complex aerosol samples and how their chemistry affects cloud formation.

State-of-the-Art Science: Peatlands to Pharmaceuticals
Mazzoleni is an associate professor of chemistry at Michigan Technological University and a recent Fulbright Scholar awardee. She is also the lead researcher on a team that is bringing a high-resolution mass spectrometer to campus through a Major Research Instrumentation grant from the National Science Foundation (NSF). The instrument is an analytical chemistry tool that identifies the type and amount of chemicals in a mixture.
