Carbon dioxide stored underground can find multiple ways to escape

When carbon dioxide is stored underground in a process known as geological sequestration, it can find multiple escape pathways due to chemical reactions between carbon dioxide, water, rocks and cement from abandoned wells, according to Penn State researchers.

Researcher pursues sustainable energy through carbon dioxide conversion

Penn State researcher Chunshan Song has a plan to address one of the most important issues facing the world today — reducing greenhouse gas emissions to curb the negative impacts of climate change.

Extracting rare-earth elements from coal could soon be economical in U.S.

The U.S. could soon decrease its dependence on importing valuable rare-earth elements that are widely used in many industries, according to a team of Penn State and U.S. Department of Energy researchers who found a cost-effective and environmentally friendly way to extract these metals from coal byproducts.

Quantitative X-ray imaging facility is moving big bytes across the network

The teeth and jaw fossil fragments from a potential new human ancestor species that roamed regions of Ethiopia more than 3 million years ago are just a few of the more noteworthy objects Tim Ryan has scanned at Penn State's Center for Quantitative X-ray Imaging (CQI). The fossils might add a new branch to humanity’s family tree and provide further evidence that multiple human ancestors once roamed Africa alongside one another.
