Valenzano on Research Funding Tour

NSFGroup Faculty Visit to Washington, DC

For the past five years, Michigan Tech deans and the vice president for research have sponsored a group visit to Washington, D.C. for early-career research faculty. To date, 70 Michigan Tech faculty and administrators have participated.

Trip participant, Loredana Valenzano shared these comments about the trip:

“What I enjoyed most was having the feeling that, indeed, PDs [program directors] and POs [program officers] are there to help, and to provide valuable guidance especially to those of us who are trying to build a career in the STEM in times where funding is decreasing and the competition is high. The availability to talk and somehow the capability to alleviate frustrations and anxieties which the people we had the chance to interact with provided, was a pleasant and encouraging revelation. I believe that having the occasion to see with our own eyes how the big machine on the East Coast works is absolutely a key aspect to shoot for success.”

Sarah Green Quoted by ThinkProgress

UQx Climate Science DenialProfessor of Chemistry Sarah Green was quoted by ThinkProgress about her contributions to the edX on-line course “Making Sense of Climate Science Denial.”

The edX course, offered by the University of Queensland, Australia, concerns theories of climate science denial, including myths, psychological and social drivers, and the influence of climate denial on public perceptions of climate change.

Green was quoted in the ThinkProgress Climate Progress article “The Massive New Online Course That Every Climate Science Denier Should Be Very Afraid Of,” stating that “educating people about facts is not sufficient.” Green, who contributed four lectures to the course, said this is especially the case when political or industry groups can “bamboozle them” with easily digestible “pseudo-facts.”

edX courses are MOOCs, or massive open online courses. “Making Sense of Climate Science Denial” is a free 7-week course taught by 13 instructors.

Chemistry-themed Student Research Symposium at NMU, April 11, 2015

Published
By

The Upper Peninsula Section of the American Chemical Society is now soliciting abstract submissions for the Student Research Symposium, which will be held at NMU’s New Science Facility in Marquette on Saturday, April 11, 2015.

The purpose of the event is to provide a venue for students to present their research in chemistry, chemical engineering and related fields. This symposium will be an excellent opportunity for students, faculty and the community at large to learn about the interesting research being conducted in the UP. This year the initiative will see the participation of presenters from schools within the Northeast Wisconsin local section.

Poster abstracts can be submitted online. The deadline for abstract submission is March 15. There is no registration fee.

Cash awards to the best posters will be given, and every participant will receive a gift from the UP local section.

Questions should be directed to Loredana Valenzano (lvalenza@mtu.edu), UPLS 2015 Chair.

Molecular characterization of atmospheric organic matter in biogenic secondary organic aerosol, ambient aerosol and clouds

ABSTRACT

Atmospheric aerosol affects the Earth’s energy budget, reduces visibility and influences human health. The organic composition of aerosol is quite complex and continuously evolves through various atmospheric processes. To gain a deeper understanding of the molecular composition of atmospheric organic matter (AOM), chamber-generated biogenic secondary organic aerosol (SOA), ambient aerosol and cloud water samples were studied. Ultrahigh resolution Fourier Transform Ion Cyclotron Resonance Mass Spectrometry was used to provide detailed molecular characterization of the atmospheric samples. Due to the extremely high mass resolution and mass accuracy, thousands of individual molecular formulas were identified in all of the samples studied. Multivariate statistical analysis methods were evaluated to compare the similarities and differences of the sample compositions. The molecular characterization of biogenic SOA, ambient aerosol and clouds will be discussed. This study of the three types of atmospheric samples helps to understand the composition of AOM with respect to atmospheric processes.
