A New Mineral Named after Physics Professor

In Mineralogical Magazine’s recent newsletter, the International Commission on New Minerals, Nomenclature and Classification announced twelve new minerals that were approved by the commission in November.

Among them is a new bismuth and gold sulfide [Bi3S3][AuS2] from Alsó-Rózsa adit, Nagybörzsöny Mountains, Pest Co., Hungary named jaszczakite, in honor of Michigan Tech professor John Jaszczak (Physics).

The new mineral was proposed by Luca Bindi (Università di Firenze, Italy;) and Werner Paar (Salzburg, Austria).

Yoke Khin Yap

Crain’s Detroit Business published three articles about Michigan Tech-based technologies that are being commercialized for the marketplace.

One is about StabiLux Biosciences, based on Yoke Khin Yap’s (Physics) research. Another describes MicroDevice Engineering, producing a battery-operated portable blood typing device developed by Adrienne Minerick (ChE, Associate Dean for Research and Innovation), and the third is about Neuvokas, a local manufacturer of fiber-reinforced polymer rebar developed by Tech alumni and tested at the University.

Cloud in a Box

Cloud Chamber20140324_0003When it comes to climate change, clouds are the wild card. Atmospheric physicists at Michigan Tech use a turbulence-generating cloud chamber to better understand the details and droplets.

There are few absolutes in life, but Will Cantrell says this is one: “Every cloud droplet in Earth’s atmosphere formed on a preexisting aerosol particle.”

And the way those droplets form — with scarce or plentiful aerosol particles — could have serious implications for weather and climate change.

It’s been known for decades that cleaner clouds tend to have bigger cloud droplets. But through research conducted in Michigan Tech’s cloud chamber, which was published by Proceedings of the National Academy of Sciences, Cantrell, graduate student Kamal Kant Chandrakar, Raymond Shaw and colleagues found that cleaner clouds also have a much wider variability in droplet size. So wide, in fact, that some are large enough to be considered drizzle drops.

Dirtier clouds, Shaw explains, not only have smaller droplets, but also much more uniformity in droplet size, with no observable drizzle drops.

“If clouds have more aerosols in them, the drops would be smaller and more similar in size,” Shaw says. “It would be harder for the cloud to rain, and the cloud would then last longer. If a cloud rains, or has less water in it, it won’t be there to reflect sunlight.”

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
