Celebrating National Chemistry Week at Sacramento's Discovery Museum

October 20, 2015

October 18-24, 2015 is National Chemistry Week (NCW) and this year's theme: "Chemistry Colors Our World!" A group of our faculty, staff and students led exciting activities and demonstrations at the Discovery Museum in Sacramento over the weekend, exploring florescence, chemical indicators and color-changing chemistry with area families.

Professor Kyle Crabtree shared some of their demonstrations with Cambi live on Good Day Sacramento: http://gooddaysacramento.cbslocal.com/show/latest-video/video-3308259-national-chemistry-week

NCW is an annual outreach event that raises public awareness of the value of chemistry in everyday life. Coordinated by the American Chemical Society, local sections, businesses, schools and individuals are encouraged to organize or participate in community activities that promote this mission.

Jessica Potts Wins STAR Award

January 21, 2015

Congratulations to Jessica Potts.  She has been chosen for the Chancellor’s Staff Appreciation and Recognition (STAR) award for her outstanding contributions to the UC Davis campus and community.  This award is presented annually by Chancellor Katehi to individuals whose achievements and conduct go “above and beyond” in support of the campus’ core values.

Letter to the Editor, Sacramento Bee from Prof. Neil Schore

January 13, 2015

Re "Affordable education" (Page A7, Jan. 24):  The author requests UC student faculty ratios.  In chemistry at UC Davis, from the early 1970s to the early 2000s, the ratio was stable. In 2003-04 we taught 11,928 students in undergraduate courses with a faculty of 37 professors, for a ratio of 322 students per professor.  By 2008-09 we taught 14,911 students, again with 37 professors (ratio of 403).  Last year we taught 18,744 students, still with 37 professors, a ratio of 507.  In a decade we added 7,000 students while the number of professors remained unchanged.

As an aside, Governor Brown's contention that research at UC takes away from teaching is simply false. We in chemistry have mentored thousands of undergraduates in cutting-edge research.  They have worked side-by-side with our graduate students, post-docs, and ourselves. Their experiences have led to increased competitiveness for positions in industry, academia, and professional schools.  Undergraduates have made important contributions and been listed as coauthors for 18 of my 30 most recent research publications.  At UC Davis, research and teaching are tightly coupled. That combination is called education.

Prof. Larsen's Love for ChemWiki Gets NSF Support

November 1, 2013

ChemWiki recently received its first major funding ̶ a grant of $250,000 from the National Science Foundation to a consortium including UCD, Sonoma State University, Diablo Valley College, Contra Costa Community College, Hope College (Michigan) and the University of Minnesota, Morris. The money will support further expansion of the wiki network and the first side-by-side comparison of the ChemWiki versus a standard textbook in classroom teaching.

While a single general chemistry textbook for undergraduates can cost hundreds of dollars, with new (and more expensive) editions appearing regularly. Moreover, the material in such textbooks is well established, in some cases for decades, if not centuries. Since the content hasn't changed greatly, Larsen and the ChemWiki development team finds it hard to justify these costs. ChemWiki began with entries written by students. Then Larsen realized that much of the material he needed already resides online, scattered across the Internet, in course notes, on professors' websites and other locations. Since all the content we need for the first two years of undergraduate chemistry already exists online ̶ the ChemWiki team went out and asked for it. When authors responded positively, Larsen and his wiki development team worked to adapt the material into the wiki format.

While still in its infancy (launched in 2008) on a shoestring budget, the ChemWiki now nets more than 2 million visitors a month, making it the most visited domain among the university's websites. Despite this, help is always accepted in developing content.

Science Without Borders

September 4, 2013

Gabriela Borba Mondo was an undergraduate chemistry student visiting UC Davis as part of "Science without Borders" from the Federal University of Santa Catarina (Brazil).  She spent her summer in the Kauzlarich Lab working with Alexandra Holmes on the synthesis of Germanium and silicon-germanium nanoparticles for energy conversion applications such as photovoltaics.

Regarding her time at UC Davis, she says, "Being abroad is, by its own, an exciting experience.  I am glad I came to UC Davis and was able to take classes and conduct research.  The experience of working in a research is very rewarding.  It is a moment where you can apply what you learned on classes in real science, and also to get a sense on how knowledge is constructed and how it is transmitted.  To me, this experience was extremely enriching, both academically and personally."

Prof Guo and Prof Navrotsky’s Work Both on Cover

June 6, 2012

Work done in Professor Guo’s group made to the cover of J. Phys. Chem. C of the May 24, 2012 issue. It is the first case of using nanostructures to concentrate energy deposition in water caused by electrons released from nanostructures under X-ray irradiation. Up to 250 times increase over the background water was predicted using a series of gold nanoshells. Also in May work done in Professor Navrotsky’s group was selected for the cover of J. Am. Ceram. Soc. Their work provided the needed experimental high temperature thermodynamic data for several rare earth oxides at over 1500 degrees Celsius.
