Electric shock to petroleum coke generates sustainable graphene

Researchers at Texas A&M University and ExxonMobil are developing a method to reprocess petroleum coke—a byproduct of refining crude oil—into a sustainable, high-value alternative. Using a chemical process called electrochemical ...

Researchers fabricate large-area sky-blue PeLEDs

The research group led by Prof. Xiao Zhengguo from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences prepared large-area and efficient sky-blue perovskite light-emitting diodes (PeLEDs) ...

Characterizing super-semi sandwiches for quantum computing

Semiconductors are the foundation of modern technology while superconductors with their zero electrical resistance could become the basis for future technologies, including quantum computers. So-called "hybrid structures"—carefully ...

Mini electricity generator made from quantum dots

Machines and electronic devices often generate waste heat that is difficult to utilize. If electricity could be generated from this waste heat, it would offer a means for a clean and sustainable power production: Such a technology ...

New view of deep rock fractures for geothermal energy

Scorchingly hot granite deep underground can be tapped for energy by opening up cracks in the rock. This potential resource, known as enhanced geothermal energy, requires a clear sense of changes happening in the rock over ...
