Engineers find way to evaluate green roofs

Green infrastructure is an attractive concept, but there is concern surrounding its effectiveness. Researchers at the University of Illinois at Urbana-Champaign are using a mathematical technique traditionally used in earthquake engineering to determine how well green infrastructure works and to communicate with urban planners, policymakers and developers.

Quick test finds signs of sepsis in a single drop of blood

A new portable device can quickly find markers of deadly, unpredictable sepsis infection from a single drop of blood.

Corn better used as food than biofuel, study finds

Corn is grown not only for food, it is also an important renewable energy source. Renewable biofuels can come with hidden economic and environmental issues, and the question of whether corn is better utilized as food or as a biofuel has persisted since ethanol came into use. For the first time, researchers at the University of Illinois have quantified and compared these issues in terms of economics of the entire production system to determine if the benefits of biofuel corn outweigh the costs.

Metal-ion catalysts and hydrogen peroxide could green up plastics production

Researchers at the University of Illinois are contributing to the development of more environmentally friendly catalysts for the production of plastic and resin precursors that are often derived from fossil fuels. The key to their technique comes from recognizing the unique physical and chemical properties of certain metals and how they react with hydrogen peroxide.

Increased number of female engineers in managerial roles brings unintended consequences

Increased female representation in the managerial ranks of engineering organizations may add another layer of sex segregation on top of the one it’s intended to mitigate, says a new paper from U. of I. labor professor M. Teresa Cardador.

Chemical array draws out malignant cells to guide individualized cancer treatment

Melanoma is a particularly difficult cancer to treat once it has metastasized, spreading throughout the body. University of Illinois researchers are using chemistry to find the deadly, elusive malignant cells within a melanoma tumor that hold the potential to spread.

Study: Higher mass transit use associated with lower obesity rates

Healthy mass transit systems could contribute to healthier communities, according to a new study by University of Illinois researchers that determined higher mass transit use was correlated with lower obesity rates in counties across the United States.

Self-healing tech charges up performance for silicon-containing battery anodes

Researchers at the University of Illinois have found a way to apply self-healing technology to lithium-ion batteries to make them more reliable and last longer.

Electroplating delivers high-energy, high-power batteries

The process that makes gold-plated jewelry or chrome car accents is now making powerful lithium-ion batteries.

Researchers develop transistors that can switch between two stable energy states

Engineers are unveiling an upgrade to the transistor laser that could be used to boost computer processor speeds – the formation of two stable energy states and the ability to switch between them quickly.
