The current revolution in materials technologies is being driven by the ability to observe and control nanometer-scale features, and even to manipulate objects the size of single molecules. Research being conducted at the Johns Hopkins Department of Materials Science and Engineering has a powerful nanoscience focus encompassing energy, devices, and biotechnology. This presentation will illustrate how the smallest domains of matter are being used to reach macro goals such as power generation, electronics on demand, and disease diagnosis. Some nanomaterials, such as gold leaf, vastly predate our very ability to comprehend the meaning of a nanometer, while others, such as organic semiconductors and magnetic nanowires, are being synthesized as we speak. All of these and much more will be vividly illustrated and discussed in the light of real world applications.
