Earlier this year, Shirley Orellana, working with CWU chemistry professor Anne Johansen, won the university’s Best Thesis Award for her master’s thesis, “Geographic Classification of Wines Using Their Elemental and Water Isotopic Composition.”</p><p>The thesis geographically classifies 133 wines from Washington state, California, Europe, and South America, using their unchanging chemical elements such as metals, non-metals and water isotopes, with the goal of helping to combat wine fraud.</p><p>"Illegal production and distribution of counterfeit wines have become a lucrative business in many parts of the world,” said Johansen. “Classifying wines to their geographic origin mitigates against illegal production and distribution of counterfeit products, thereby protecting wine makers' reputation and revenue.”</p><p>The two researchers concluded that 11 elements are significant for classifying wines from these geographic regions, with manganese, zinc, and lead being the three most significant elements.</p><p>Orellana and Johansen are the first to offer a chemical profile, or “fingerprint,” for Washington terroir.</p><p>“In this study, we built a chemical database that successfully assigned Washington state wines to their regional origin," said Johansen.</p><p>Orellana, who came to CWU to study chemistry as an undergraduate, worked for a Prosser winery called Mercer Wine Estates.&nbsp; While there the lab manager sparked her interest in the types of wine research available and connected her with Johansen.</p><p>An article on Rudy Kurniawan, a wine collector and perpetrator of one of the United States’ largest wine fraud cases where he sold close to $30 million in counterfeit wine, was Orellana’s motivation in choosing wine fraud as her research project.</p><p>Orellana and Johansen will present their wine research at the Science in a Pint event, at 7 p.m. on September 4, at Cornerstone Pie in Ellensburg.

Central Washington University’s Department of Geological Sciences hosts an air quality and weather monitor on its website,</p><p>The monitor is a science geek’s dream—all you could ever want to know about atmospheric conditions, barometric pressure, particulate matter and ozone concentrations—all in real time.</p><p>The monitor is located on the top of the Science II building on the CWU campus. It came about as a collaboration with the Departments of Geological Sciences and Chemistry, and a senior capstone project of the Department of Computer Science. The monitor has precision sensors that measure a number of different parameters, including the concentration of particulates in the air. A high concentration of fine particles, also referred to as PM2.5 (i.e., particulate matter with diameter smaller than 2.5 micrometer), as seen with the current dense wildfire smoke, can be dangerous upon inhalation.</p><p>“It’s really an amazing device,” said Anne Johansen, CWU chemistry professor, and advisor for the project. “The students were ingenious in developing a user-friendly web interface that could relay results in real time and also allow for viewing past data. With these sensitive instruments, we can evaluate minute changes in air quality.”</p><p>The air quality monitor link can also be found on CWU’s annual fire watch website,, which provides current updates on fires in central Washington.</p><p>Media Contact: Valerie Chapman-Stockwell, Public Affairs, 509-963-1518,<br>&nbsp;</p></br>CWU Alumna Named ACS Fellow, 16 Aug 2017 08:04:10<p><img alt="" src="/chemistry/sites/" style="width: 158px; height: 174px; border-width: 1px; border-style: solid; margin: 4px; float: left;">Aurora Clark, a WSU professor of chemistry, has been named a Fellow of the American Chemical Society.</p><p>Clark received her BS in chemistry from CWU in 1999.</p><p>Clark received the prestigious award for her service to the nuclear/inorganic and computational chemistry communities and for her innovative research, including the pioneering use of computer algorithms and network analysis to understand the behavior of complex solutions and their interfaces.</p><p>Read more of this story in <em><a href="" target="_blank">WSU News</a></em>.</p><p>Wednesday, August 16, 2017</p>Yingbin Ge's Transition Metal Catalyst Research Funded by ACS, 20 Apr 2017 12:31:33<p>Yingbin Ge's proposal, titled "Theoretical design of long-life efficient transition metal nanocatalysts towards the activation of C-H bonds at low temperatures," is funded by the American Chemical Society Petroleum Research Fund in the amount of $70,000.

His mentor, chemistry professor Anne Johansen, encouraged him to apply for the award when he was a sophomore. Rodriguez was the only person in Washington State, and one of only two in the Pacific Northwest to receive this prestigious fellowship.</p><p>The award will provide funding for tuition, travel costs to EPA conferences, lab costs and a stipend for living expenses. As part of the fellowship, Rodriguez will attend a 12-week summer internship at an EPA’s Western Ecology Division Laboratory in Corvallis, Oregon. There he will assist in research to determine the potential effects of engineered nanoparticles on terrestrial ecosystem resources. In essence, he will be studying the effects of pollution from manufacturing processes and how they settle into soils.</p><p>“The nanoparticles may react with natural organic compounds, such as humic acids, in the presence of light,” he explained. “And in this way, they may be producing radical compounds that have a negative effect on the environment and biological systems.”</p><p>A participant in CWU’s <a href="" target="_blank">Science Talent Expansion Program (STEP)</a>, Rodriguez has been working with Johansen on the toxicity of air pollution nanoparticles in cellular environments. For his EPA grant he will be focusing on the reaction of these nanoparticles in soils.</p><p>“He thinks carefully of what he is doing, and has excellent communication and organizational skills,” said Johansen. “These characteristics have allowed him to be effective at problem solving when left alone in lab. In 15 years of teaching, I consider him one of the best students I have encountered.”</p><p>A 2013 graduate of River Ridge High School near Olympia where he grew up, Rodriguez is from German and Puerto Rican descent. From a young age he was fascinated in the natural world and unlocking its secrets. Coming into college he knew he wanted to pursue a degree in science.</p><p>“I didn’t decide to pursue chemistry until I took Chemistry 181. I fell in love with its complexity and it ability to explain the world around us, and I knew it would be a good challenge”</p><p>Rodriguez plans to pursue a master’s degree in chemistry, and ultimately plans to work in an EPA facility solving environmental issues.&nbsp;</p><p>“I hope to lead by example and open doors to more minorities getting into science in general.”</p><p><br>“With the help of this funding, undergraduates will be able to explore their passion in environmental science and cultivate their research skills,” said Thomas A. Burke, EPA science advisor and deputy assistant administrator of EPA's Office of Research and Development. “These fellows are the next generation of scientists, who will help lead the way in protecting the environment and public health.”</p><p>The EPA Greater Research Opportunities (GRO) Fellowships for Undergraduate Environmental Study winners receive fellowships of up to $50,000 for their last two years of undergraduate study and a three-month summer internship at an EPA facility.&nbsp; By enhancing and supporting quality environmental education for undergraduate students, the GRO Undergraduate Fellowship encourages promising students to pursue careers in environmentally related fields and to continue their education beyond the baccalaureate level.

The deadline for this year’s applications is April 1. Students can apply at</p><p>Community college students who wish to transfer to CWU are especially encouraged to apply. Up to 10 students may be found eligible for the award.</p><p>Thanks to a $612,840 National Science Foundation grant, the scholarship program, SOLVER (Sustainability for Our Livelihood, Values, Environment, and Resources), can help promising students through the last, most difficult years of their science degree program.</p><p>“The scholarships are for $10,000 per year,” said Audrey Huerta, professor of geological sciences, and one of the principal investigators of the grant. “If the student does well in the first year of their award, they are eligible for the second $10,000.”</p><p>The overall objective of SOLVER is to increase the quality and diversity of students graduating with bachelor’s degrees in the STEM fields, with an emphasis on recruitment, retention, and graduation of Hispanic and Native American students. The SOLVER program will provide scholars with financial, academic, personal, and professional support.</p><p>“Our goal is to substantially increase the success of traditionally underrepresented minorities in these high-demand fields,” said Huerta.</p><p>In addition to the $10,000 academic-year scholarship, students are automatically enrolled in the Hearst Summer Fellows program. Instead of leaving campus and working low-wage jobs in the summer before their senior year, students can spend their summer involved in meaningful research. The Hearst Foundations awarded $100,000 to provide summer research fellowships to 20 Solver Scholars at CWU for the next three years.</p><p>“This is the missing piece of the puzzle,” said Audrey Huerta. “Almost all of our students have to work during the summer to make money for the school year. It’s impossible for them to take advantage of unpaid research internships that would help further their academic career. This stipend allows them to immerse themselves in science without worrying about financial consequences.”</p><p>Fall quarter 2016 will initiate the third year of the SOLVER program, and already, there are success stories from its graduates.</p><p>“Our SOLVER students have been sought after for professional positions even before graduation,” Huerta related. “Many others are pursuing advanced degrees in their field.”</p><p><br>Media Contact: Valerie Chapman-Stockwell, Public Affairs, 509-963-1518,</p><p>March 9, 2016</p></br>
