Chicago Tribune (Sept. 18) -- It might be the next big breakthrough in high-tech, 3-D fabrication, and it got its inspiration in part from a pop-up Christmas card. Researchers at Northwestern University and Illinois say they have developed a way to create complex 3-D structures from flat surfaces, which could revolutionize a host of areas such as semiconductor manufacturing, building construction and tissue regeneration. MatSE professor John Rogers served as the other corresponding author of the paper, “A mechanically driven form of Kirigami as a route to 3D mesostructures in micro/nanomembranes.” Also: Chicago Inno (Sept. 17).
