University art conservation student prepares Blue Hen for display

When University of Delaware Prof. Jack Gelb, Jr., was given a taxidermy specimen of a Blue Hen by a retiring colleague in the Department of Animal and Food Sciences, he realized that this particular example of the Delaware state bird was somewhat the worse for wear.

And so Gelb, who is chairperson of the department as well as director of UD’s Avian Bioscience Center, turned to the Department of Art Conservation for expert help.

“This was a wonderful opportunity for me to learn about natural history materials,” said Elena Torok, now a third-year graduate student in the Winterthur-University of Delaware Program in Art Conservation. “We happily agreed to work” on the project. (more…)

UD researchers report progress in development of carbon nanotube-based continuous fibers

The Chou research group in the University of Delaware’s College of Engineering recently reported on advances in carbon nanotube-based continuous fibers with invited articles in Advanced Materials and Materials Today, two high impact scientific journals.

According to Tsu-Wei Chou, Pierre S. du Pont Chair of Engineering, who co-authored the articles with colleagues Weibang Lu and Amanda Wu, there has been a concerted scientific effort over the last decade to “go big” – to translate the superb physical and mechanical properties of nanoscale carbon nanotubes to the macroscale.

First UD student successfully defends doctoral dissertation via Skype

Samuel Mathey, a graduate student in the Department of Economics at the University of Delaware, has become the first doctoral student in the Alfred Lerner College of Business and Economics to successfully defend a dissertation via Skype.

On Tuesday, June 12, Mathey’s dissertation committee sat in a Pearson Hall video conference room on UD’s Newark campus while he attended his defense virtually from France.

Committee members for Mathey’s defense included Burt Abrams (chair), professor of economics; Jim Butkiewicz, professor of economics; Laurence Seidman, professor of economics; and Robert Schweitzer, professor of finance. (more…)

Experimental watershed provides new insights, rich educational experience

Six years and about 4,000 water samples later, an outdoor experimental watershed laboratory established by University of Delaware faculty members Shreeram Inamdar and Delphis Levia at Fair Hill, Md., is now producing valuable data and novel insights into how water and chemicals move through the forest canopy, soils and watersheds, and how future climate change may impact or alter such responses.

Inamdar, associate professor in the Department of Plant and Soil Sciences, has investigated the role of soils, streams, and watersheds in leaching water and nutrients, while Levia, professor in the Department of Geography, has studied the interactions of atmosphere and the forest canopy in leaching water and nutrients. Together, they have provided a complete picture of watershed hydrology and biogeochemistry. (more…)

UD’s Schmidt studies genome of crocodile family in evolution research

University of Delaware scientist Carl Schmidt is working to identify genes in crocodiles, alligators and gharials as he searches for links between the creatures that could give clues as to how they evolved over the years in relation to one another.

Schmidt’s effort is part of a National Science Foundation-funded project being conducted by a team of researchers assembled by David Ray, an evolutionary biologist at Mississippi State University. (more…)

UD’s McCarthy part of group that films rare striped rabbit in Sumatra

With cameras set up in Sumatra looking for medium- and small-sized wild cats, such as leopards, a research group involving the University of Delaware’s Kyle McCarthy, found images of something else entirely — a rabbit. Not just any ordinary rabbit, but a Sumatran striped rabbit, one of the world’s rarest species and one that had been captured on film only three times before.

There has never been a viable study of the Sumatran striped rabbit and McCarthy, assistant professor in the Department of Entomology and Wildlife Ecology in the College of Agriculture and Natural Resources (CANR), said that while his group plans on continuing their study of small cats, they are now also focusing on the rare rabbit species.

Marine science majors conduct field research with horseshoe crab census

Wearing sneakers and rain boots, University of Delaware freshmen got their feet wet as marine biologists recently while counting horseshoe crabs along the Delaware Bay. The students participated in a monitoring effort to gain firsthand experience in field research with their fellow marine science majors.

“Where else can you go on a Saturday night to count horseshoe crabs?” freshman Will Goldman said. (more…)

For two molecules on blind date, new method predicts potential for attraction or repulsion

Krzysztof Szalewicz, professor of physics and astronomy at the University of Delaware, and Rafal Podeszwa of the University of Silesia Institute of Chemistry in Poland have developed and validated a more accurate method for predicting the interaction energy of large molecules, such as biomolecules used to develop new drugs.

The research is reported as a communication in the April 27 issue of the Journal of Chemical Physics, which is the most highly cited journal in atomic, molecular and chemical physics according to Thomson Reuters. The journal is published by the American Institute of Physics. Despite appearing at the end of April, the paper was on the list of the 20 most-read articles in JCP for that month. (more…)
