Chemistry Day

Jason Kautz (l), associate professor of practice for Chemistry, shows how an acid and base interact with each other.  The event drew 65 people to learn more about chemistry and the department.

A student heated potassium chlorate and a gummy bear to show the amount of energy released by sugar through digestion.

Graduate student played Dr. T-Fresh, resident mad scientist who claimed to be the inventor of organic chemistry while interviewing people.

High school student Alex Wynn displayed his chromatography T-shirt made during Chemistry Day. He won one of six $500 scholarships to attend UNL as a chemistry major.

Participants were given 15-minute mini-tours of three labs, each led by a professor.  There were also experiments, discussion about chemistry as a career, an intro to the UNL program, T-shirt making, a "Chemistry in the Movies" lecture by professor Mark Griep, and a roundtable discussion for teachers only.

Jay Keasling

Jay Keasling, a Chemistry and Biology alum, was named Discover magazine's first Scientist of the Year in 2006 and was featured on The Colbert Report.

Working in the field of synthetic biology, Dr. Keasling wants to make many genes work together as a microbe that produces a cure for malaria.  The cure will be produced at a fraction of its current cost, making it much more accessible and possibly saving many lives.

He spoke at UNL on Friday September 25, 2009.

Mark Griep

After two solid years of study and writing, plus the time it took to find funding to do the research, "ReAction! Chemistry in the movies" comes from watching more than 300 movies and sorting them into themes.

Self-cleaning walls, counter tops, fabrics, even micro-robots that can walk on water -- all those things and more could be closer to reality because of research recently completed by scientists at the University of Nebraska-Lincoln and at Japan's RIKEN institute.

UNL chemistry professor Gerard Harbison was a featured presenter at the American Chemical Society national meeting in Salt Lake City where he spoke at a news conference about UNL research about computer simulations to analyze potential peroxide-based explosives.

The ACS chooses news to feature for national media at the convention, and his virtual news conference was watched live and repeated worldwide, and hundreds of news stories resulted from the chemical society's publicity.

In his presentation Harbison challenged the theory that terrorists could produce a new and dangerous form of the explosive responsible for airport security screening of passengers' shoes and restrictions on carry-on liquids. 

He and colleagues investigated the structure of a claimed explosive, tetracetone tetraperoxide, and determined that the material would be unlikely, because it is too unstable for a practical synthesis, and too sensitive to be used as weapons.

"The good news is basically this (TeATeP) is something we don't have to worry about. The internet myths are nothing more than that," Harbison told the ACS.

The UNL research group did computer simulations to analyze a variety of potential peroxide-based explosives in the same class as triacetone triperoxide, the powerful, easy-to-make explosive used by "shoe bomber" Richard Reid in his failed attempt to blow up a transatlantic flight in 2001, and by suicide bombers.

The American Chemical Society has more than 154,000 members and is the world's largest scientific society and a global leader in providing access to chemistry-related research.

"Des" was a skilled synthetic organic chemist whose background included postdoctoral research with the Nobelist R. B. Woodward.

Des one time chaired the Academic Senate and also received the prestigious James A. Lake Academic Freedom Award (1982) for the furtherance of Academic Freedom.

In his younger days, Des could regularly be found playing squash at the "University Club" on the top of the old Stuart Building or golf on one of the local courses, all of which he knew well.

He and his spouse, Dr. Maureen Wheeler, worked together at UNL on research directed toward improving synthetic routes to powerful anticancer drugs. Des and Maureen had returned to Ireland in retirement; he is survived by his wife.

Nan Shao

"When I was looking at schools, I wanted to find somewhere with a great department, but not a huge department. Students can't focus on research at a huge school. UNL had the perfect mix – a perfect size department in the perfect size town of Lincoln."

There are over 4400 graduate students at the University of Nebraska and a multitude of graduate fellowships given but Nan Shao, a PhD Student in Physical Chemistry with Dr. Xiao Cheng Zeng has been the student chosen to receive UNL's 2008 most prestigious fellowship, the Presidential Fellowship. It is awarded only to those graduate students who have demonstrated the highest levels of academic performance. The purpose of the fellowship is to allow a graduate student to immerse themselves in scholarly and research activities during the final year of a degree program. The award carries with it a stipend, tuition, fees and health insurance payment.

Nan Shao came to UNL from China and loves the research opportunities she has been given as a student.

"I am studying the theoretical simulations of clusters by using quantum and empirical methods to look for the lowest energetic isomers with good chemical properties.What makes me excited to study at UNL is the computational chemistry, which could help people to explore the unknown world by the most accurate ab initio calculations. It's something new and exciting, and something I really enjoy!"

"The lab I work in is very free. Of course research has to pertain to the research being covered in my professor's lab, but if I want to do a little of my own research, I can pursue that knowing that Dr. Zeng supports me. There is a great environment for research here at UNL."

Nan also has enjoyed learning from the other faculty in the chemistry department.

"The teaching here is very strong. I took three classes from Dr. Langell – she is a great teacher! Everyone loves her classes. I've had nothing but good experiences with the teachers I had here. All of the faculty is very trustworthy, helpful, and friendly. They are always willing to help if they can."

Nan's current work focuses around the theoretical simulation of chemistry. In the future, she hopes to continue to pursue this, and nanoscience simulations in particular. Throughout her tenure at UNL, Nan has published eight papers and was awarded the Chemistry Department Graduate Research award in 2008.
