 Group News : Collaborating with Chinese scientists
Posted on 2015/6/22 15:00:00

The recent announcement of the creation of the Global Innovation Exchange (GIX), a pioneering partnership between the University of Washington, Beijing-based Tsinghua University and Microsoft, underscores the ongoing cooperation between the Jaffe Group and scientists in China. Two papers published in 2015 involved collaborations between the Jaffe Group and scientists at Sichuan University, Chengdu, China.

Evaluation of air quality in Chengdu, Sichuan Basin, China: are China's air quality standards sufficient yet? by Xue Qiao, Dan Jaffe, Ya Tang, Meaghan Bresnahan and Jie Song

In addition, earlier in 2015, the Jaffe Group hosted Lei Zhang, a visiting scientist from Tsinghua University. Lei's research at the UW focused on identifying and quantifying speciated GOM (gaseous oxidized mercury).

GIX will train innovators to address some of the world's biggest problems. “In the face of global challenges related to the environment, resources and health, we need to cooperate across national boundaries to find solutions,” said Tsinghua University President Qiu Yong. We are excited by this new ground-breaking collaboration and look forward to continued cooperation with our Chinese colleagues.

 Group News : UWB Chemistry student wins ACS scholarship and 4 students present research at American Chemical Society's Undergraduate Symposium
Posted on 2015/5/12 11:50:00

The Puget Sound chapter of the American Chemical Society (ACS) held their annual Undergraduate Research Symposium on April 25, 2015, at Pacific Lutheran University. Four UWB students--Angela Angelevska, Virkamal Dhaliwal, Xin Gao and Anthony Stillman--presented the results of their research in Biochemistry and Environmental Chemistry. A highlight of the day was Taryn Meacham being awarded an ACS scholarship to be used towards her undergraduate Chemistry education at UWB!

Angela Angelevska presented "Developing an analytical cryofocusing method to measure volatile organic compounds in ambient air." Her research mentor is Dr. Dan Jaffe.

Virkamal Dhaliwal presented "Expression and purification of homing endonuclease I-LtrWI." Her research mentor is Dr. Lori Robins.

Anthony Stillman and Xin Gao presented "Sulfur leaving group kinetic isotope effects for the butyrylcholinesterase-catalyzed hydrolysis of formylthiocholine." Their research mentor is Dr. Lori Robins.

 Group News : Paws on Science at the Pacific Science Center
Posted on 2015/5/4 13:40:00

Young scientists investigated carbon dioxide and ocean acidification at the University of Washington Paws on Science event at the Pacific Science Center on April 10-12, 2015. The Jaffe Group huskies and other Chemistry faculty and students donned lab coats and guided experiments on measuring CO2 in breath and what happens when CO2 is blown into a cup of water. Participants examined shells to see real-life evidence of how increasing levels of CO2 in oceans is harming sea life. We hope to have some of these young scientists on campus as UW students in the next few years.

Two other groups from the University of Washington Bothell (UWB) School of STEM also participated: Ivan Owen coordinated the exhibit Designing Body Parts, and Breanna Binder and Subramanian Ramachandran coordinated the exhibit Physics around Us. Over 25 volunteers from UWB participated in the event.

 Group News : Central Oregon STEM night: Investigating CO2
Posted on 2015/4/21 14:40:00

- Why is there CO2 in my breath?
- Is CO2 a problem?
- What is an acid?
- Why does my breath change the acidity (pH) of water?

These are a few of the questions STEM night participants addressed at the Bend, Oregon, event in February 2015. Equipped with a pH meter, an instrument that measures CO2, a chemical pH indicator, water and hundreds of straws and cups, three Jaffe Group members guided budding scientists through measuring CO2 in their breath, measuring the pH of water and exploring what happens when CO2 is added to water.

Participants learned that we care about CO2 because CO2 is making our oceans more acidic, and this harms sea life. The CO2 in our breath is not the problem. It is humans' use of fossil fuels that is the problem. Fossil fuel emissions are increasing the levels of CO2 in the oceans and causing ocean acidification.

This event was also an opportunity for Bend-area residents to learn about the Jaffe Group Mount Bachelor Observatory, located right in their backyard.

 Airborne Research : Jaffe Group presents 5 papers at AGU
Posted on 2015/3/10 12:40:00

At the American Geophysical Union (AGU) meeting in December 2014, Jesse Ambrose, Lynne Gratz and Dan Jaffe gave presentations on the NOMADSS (Nitrogen, Oxidants, Mercury, and Aerosol Distributions, Sources, and Sinks) study.

- Observations and Model Analysis of Enhanced Oxidized Mercury in the Free Troposphere During NOMADSS by Lynne Gratz
- A Comparison of Inventoried and Measured U.S. Urban/Industrial Hg Emission Factors during the NOMADSS Experiment by Jesse Ambrose
- Aircraft Observations of Mercury over the US: The NOMADSS Experiment by Dan Jaffe

The NOMADSS study gathered airborne measurements of mercury in the eastern US during the summer of 2013.
To read more about this project, click here.

Dan Jaffe also gave two other presentations at the meeting:
Crowdfunding: Right for Me? and Ozone from Wildfires: Peering through the Smog

The figure below, from Jesse Ambrose's presentation, shows measurements from three NOMADSS research flights. The numbered total mercury (THg), nitrogen oxide (NOx) and sulfur dioxide (SO2) plumes shown in the figure were attributed to coal-fired power plants.
