Making a Solar Energy Conversion Breakthrough With Help From a Ferroelectrics Pioneer
August 8, 2016
Designers of solar cells may soon be setting their sights higher, as a discovery by a team of researchers has revealed a class of materials that could be better at converting sunlight into energy than those currently being used in solar arrays. Their research shows how a material can be used to extract power from a small portion of the sunlight spectrum with a conversion efficiency that is above its theoretical maximum — a value called the Shockley-Queisser limit. Jonathan E. Spanier, PhD, a professor of materials science, physics and electrical engineering and an IExE affilated faculty member explains that "Barium titanate absorbs less than a tenth of the spectrum of the sun. But our device converts incident power 50 percent more efficiently than the theoretical limit for a conventional solar cell constructed using this material or a material of the same energy gap."
SDG6: Who is keeping score?
July 18, 2016
"On the 2nd of August 2015, UN member states unanimously adopted 17 goals and 169 targets for Transforming our World: The 2030 Agenda for Sustainable Development. The vote marked an end to the gruelling three year process through which hundreds of groups boiled down thousands of discussions into one water and sanitation goal. The ambition is to mitigate urban water challenges, ensure access to basic services, treat wastewater, and mitigate the impact of water-related disasters in cities, says Gérard Payen of Aquafed, who believes SDG6 “will create a revolution in the water world”. Adoption of the goal however has created numerous questions about how progress will be measured and who will receive funding for implementation. Erin Graham, PhD, assistant professor of politics and IExE affiliated faculty member was asked about some of the specific tensions and potential outcomes these questions have raised.

US-China Environment and Urban Public Health Summer Internship
July 14, 2016
Increasing urbanization and climate change are two of the great challenges in the 21st century. An estimated 6.2 billion people – two-thirds of the world’s population – will be living in cities by 2050. Globally, cities currently account for about two-thirds of the world’s energy consumption and about 70 percent of greenhouse gas (GHG) emissions. Researchers in policy, education and science from Drexel University and Shanghai Advanced Research Institute (SARI) of the Chinese Academy Sciences are working together to address these global challenges and searching for solutions that move us toward low-carbon and healthy cities.
The Summer Internship, US-China Environment and Urban Public Health sponsored by University Office of International Programs, Drexel–SARI Project, and A.J. Drexel Institute for Energy and the Environment has two overall goals: (1) to provide opportunities for students to participate in ongoing research projects related to environmental factors contributing to an increasing burden of noncommunicable diseases (cardiovascular disease, diabetes, respiratory disease, and cancer etc.) in urban cities, (2) to serve as a platform for students to learn the basics of study design, data collection and analysis applied in public health, environmental epidemiology and prevention.

Q+A: Post-Paris, America’s First Step To Reduce Greenhouse Gas
January 4, 2016
As part of the 2015 Paris Climate Conference in December, the United States supported a proposal to cut global emissions of greenhouse gas in hopes of stalling global temperatures from rising as much as 3.6 degrees Fahrenheit by the year 2100 — a benchmark scientists say would be of great concern. Days later the U.S. Department of Energy took the first step toward reaching this goal when it announced new energy efficiency standards for commercial air conditioners and furnaces. According to the DOE, the new standards are the largest energy efficiency standard in US History with expected utility savings to business of $167 Billion and a reduction in carbon pollution of 885 million metric tons over 30 yrs
Read a Q+A with Drexel environmental engineering professor Patrick Gurian, PhD, who recently led a team including researchers from the the A.J. Drexel Institute for Energy and the Environment that produced a plan for the city of Philadelphia to cut its greenhouse gas emissions by 80 percent by the year 2050, to see why this was the first move coming out of the Paris meeting and what other carbon-reducing changes could be on the horizon.

Are We Wasting Our Energy (And Land) on Biofuels?
February 4, 2015
"A recent report by the World Resources Institute suggesting that policy changes are necessary in Western countries to phase out the use of agricultural land for growing crops that will be made into biofuels. In the United States alone, 30-40 percent of corn crops are being converted to fuel additives. But the report indicates that our efforts to turn plant matter into liquid fuel are barely a drop in the gas tank when it comes to satisfying the world’s energy demand." Sabrina Spatari, PhD, Associate Professor in the Civil, Architectural and Environmental Engineering Dept. answers questions raised by the report and biofuels more broadly.

On The Road Again…This Time, It’s For Air Quality Testing
June 24, 2014
“Cities like Philadelphia have a network of fixed air pollution monitors that track our air quality for regulatory purposes,” said Peter DeCarlo, PhD, an assistant professor in the College of Engineering and the group’s advisor. “These sites are expensive to run and maintain, so there is a limit to the number of sites that can be supported. A mobile measurement facility allows us to take our measurements anywhere, and characterize air quality and emissions from facilities at a neighborhood to city scale, complementing the fixed site monitors run by the city.”
<aDr. Mimi Sheller, Director, Center for Mobilities Research and Policy, and Professor of Sociology, publishes Aluminum Dreams, The Making of Light Modernity.</a
June 9, 2014
"Despite the fact that aluminium makes up one-twelfth of the Earth’s crust, and is the third most common element on the planet (after oxygen and silicon), aluminium is hard to get at in its pure form and exists mostly locked away in bauxite. It takes four tonnes of bauxite to create one ton of primary aluminium and the big producers are Australia, Brazil, China, Guinea, Jamaica and Vietnam. Heavy consumers include the United States and the Middle East, and this unequal distribution has the potential to create political tensions such as those we’ve seen in the international oil markets. Other issues, such as encroachment onto indigenous peoples’ lands, human rights and environmental degradation make production something of a mixed blessing."
