Crystal defect research holds information for new material design

Defects in the crystal destroy the order of six-fold rotational symmetry. The structure on the left displays particles arranged in a pentagonal lattice; the structure on the right is a heptagonal lattice.

New study finds how defects affect two-dimensional crystalline structures, and the results hold information for designing new materials.

Anti-cancer system bursts nanoballoons with lasers

The image shows a nanoballoon before (left) and after (right) being hit by a red laser. The laser causes the balloon to pop open and release the anti-cancer drugs directly at a tumor. Image: Jonathan Lovell.

New drug delivery method targets cancer cells – not the entire body – and limits chemotherapy side effects.

New graphene material is reinforced with nanotube bars

A square-centimeter sheet of rebar graphene floats in water. The rebars allow the sheet to be transferred from one surface from another without using polymer in an intermediate step. The process was created in the lab of chemist James Tour at Rice University. Image: Tour Group/Rice University.

Rice University lab makes hybrid nanotube-graphene material that promises to simplify manufacturing.
