MSE faculty and students work actively to make light-weight engine components out of aluminum and magnesium in order to boost fuel efficiency. They also pioneer improved high-temperature materials that are important for efficient jet engines and electricity generation. To restore hearing to deaf people and sight to blind people prosthetic devices must make contact between the brain and a microphone or camera. MSE faculty and students work to find ways to Interface silicon technology to neural tissue. This requires the development of coatings that are biocompatible and electrically conducting. Moores law states that the number of transistors on the latest computer chip doubles approximately every 18 months. This translates into more memory and faster, cheaper computers. But there is a limit to the density of transistors that can be placed on a computer chip using current technology. MSE faculty and students develop methods to spontaneously generate structures a few tens to hundreds of atoms across to form the basis for quantum computers. These next generation computers will exploit the physics of quantum confinement that dominate at that tiny scale. Making components out of new materials often involves an extensive cycle of design, creation, testing and redesign. This process is costly and time consuming. MSE faculty and students develop computer
