Using the Fork in a Tree
Currently, when trees are harvested, the places where tree limbs fork are cut out and used for mulch or other low tech uses. Researchers at MIT are discovering that these forks in trees are actually extremely strong and have load carrying properties that cannot be duplicated even by processes like 3D printing. Dr. Caitlin Mueller, Associate […]
With DTC, Perseverance Can Pay Off!

Researchers Create a Better Carbon Dioxide Filter
Scientists at the University of Delaware have developed a method to efficiently remove carbon dioxide from the air using technology from fuel cells and, in doing so, help solve a roadblock to adopting fuel cell technology. The research team work with hydroxide exchange membrane (HEM) fuel cells that convert hydrogen to water and produce electricity. […]

New Ways to Turn Waste Heat into Electricity
Researchers at Penn State have developed a practical way to harness the energy from curved, hot surfaces and convert it to electricity. Devices known as thermoelectric generators have been around for some time. They use silicon and other compounds to convert heat into a small electric current. These devices have been mounted onto rigid metal […]
