Tilt (3 of 3) (IMAGE) Rice University Caption Researchers at Rice University and Oak Ridge National Laboratory predict and confirmed that two-dimensional materials grown onto a cone allows control over where defects called grain boundaries appear. At left, a Rice model predicts how a grain boundary would form on a steep cone and extend onto a shallow cone. Scientists at Oak Ridge confirmed the prediction when they created the material seen in an electron microscope image at right.
