Rice University scientists have developed a simple way to produce conductive, three-dimensional (3D) objects made of graphene foam. The squishy solids look and feel something like a child’s toy but offer new possibilities for energy storage and flexible electronic sensor applications. The technique detailed in advanced materials is an extension of groundbreaking work by the
Artificial intelligence—specifically, machine learning—is a part of daily life for computer and smartphone users. From autocorrecting typos to recommending new music, machine learning algorithms can help make life easier. They can also make mistakes. It can be challenging for computer scientists to figure out what went wrong in such cases. This is because many machine
Rice researchers show how to optimize nanomaterials for fuel-cell cathodes. Nitrogen-doped carbon nanotubes or modified graphene nanoribbons may be suitable replacements for platinum for fast oxygen reduction, the key reaction in fuel cells that transform chemical energy into electricity, according to Rice University researchers. The findings are from computer simulations by Rice scientists who set
