UD researchers studying ‘fingerprint’ left on seafloor by Hurricane Sandy

Beneath the 20-foot waves that crested off Delaware’s coast during Hurricane Sandy, thrashing waters reshaped the floor of the ocean, churning up fine sand and digging deep ripples into the seabed. Fish, crustaceans and other marine life were blasted with sand as the storm sculpted new surfaces underwater.

UD scientists cued up their instruments to document the offshore conditions before, during and after Sandy’s arrival to scrutinize the differences and better predict the environmental impact of future storms. (more…)

Teaching future educators how to read and write in a new way

Rachel Karchmer-Klein, an associate professor in the University of Delaware’s School of Education, is teaching future educators to read and write multimodal texts, which includes everything from literature on a Kindle or iPad to information on a website.

“With traditional texts we teach students to read left to right, top to bottom, but electronic text is different because it contains multiple modes,” Karchmer-Klein explained. (more…)

UD doctoral student studies ways to improve lithium battery performance

Lithium batteries are used in many devices such as cell phones, computers and cameras, among others.

University of Delaware doctoral student Wei-Fan Kuan is investigating ways to improve membranes used in lithium batteries by capitalizing on the innate properties of block copolymers.

It is work that he believes will become increasingly important as the components in electronic devices continue to get smaller. (more…)

Astronomers poised for galactic chow-down

The super-massive black hole at the center of the Milky Way Galaxy has a healthy appetite, frequently snacking on asteroids and comets. Now, a cloud of gas and dust called G2 is on a dangerous course to become its next meal.

Even though Sagittarius A* (pronounced “Sagittarius A-star”) hasn’t been easy to see through the cosmic dust, sitting 25,000 light years away at galaxy central, scientists know it is a black hole — and a hungry one at that. Its weight has been estimated to be more than that of 4 million suns. (more…)

“the result of humanity’s attempt to carve out an ideal place in nature, thereby fashioning a ‘perfect’ earth” — is the subject of a new book, co-authored and edited by the University of Delaware’s Annette Giesecke.

Earth Perfect? Nature, Utopia, and the Garden is a lushly illustrated, 303-page volume that brings together essays from writers and experts across disciplines to study the relationship — historical, present and future — between humanity and the garden. (more…)

Lecturer explores the imperatives of environmental ethics

Speaking to University of Delaware faculty and students and community members in Brown Lab on Monday night, Oct. 15, environmental philosopher Kathleen Dean Moore discussed how important it is for humans to realize their ethical responsibility to save the world from a climate crisis.

In a lecture titled “Why It’s Wrong to Wreck the World: Climate Change and the Moral Obligation to the Future,” Moore reflected on the relationship humans have with the environment and argued that once humans realize the impact of their actions, they will naturally feel a moral obligation to care for the planet.

UD prof leads photonics revolution to help researchers access high-tech foundry services

Michael Hochberg joined the University of Delaware in the spring of 2012 as an associate professor in electrical and computer engineering.

An industry leader in silicon photonics and large-scale photonic-electronic integration, Hochberg is renowned for establishing Optoelectronic Systems Integration in Silicon (OpSIS), a high-tech foundry service for silicon photonics in which the community shares the cost of fabricating complex chip-scale systems across many projects.
