  • A Course in Micro and Nanoscale Mechanics
    Session 1168 A Course in Micro- and Nanoscale Mechanics Wendy C. Crone, Robert W. Carpick, Kenneth W. Lux, Buck D. Johnson Department of Engineering Physics, Engineering Mechanics Program, Department of Biomedical Engineering, Materials Research Science and Engineering Center on Nanostructured Materials and Interfaces, University of Wisconsin-Madison, Madison, WI 53706, USA Abstract At small scales, mechanics enters a new regime where the role of surfaces, interfaces, defects, material property variations, and quantum effects play more dominant roles. A new course in nanoscale mechanics for engineering students was recently taught at the University of Wisconsin - Madison. This course provided an introduction to nanoscale engineering with a direct focus on the critical role that mechanics needs to play in this developing area. The limits of continuum mechanics were presented as well as newly developed mechanics theories and experiments tailored to study and describe micro- and nano-scale phenomena. Numerous demonstrations and experiments were used throughout the course, including synthesis and fabrication techniques for creating nanostructured materials, bubble raft models to demonstrate size scale effects in thin film structures, and a laboratory project to construct a nanofilter device. A primary focus of this paper is the laboratory content of this course, which includes an integrated series of laboratory modules utilizing atomic force microscopy, self-assembled monolayer deposition, and microfluidic technology. Introduction Nanoscale science and technology are inspiring a new industrial revolution that some predict will rival the development of the automobile and the introduction of the personal computer.1 By observing and manipulating materials at the nanoscale, researchers have been able to develop new materials with novel and extreme properties.

  • Chapter 6 Online Nanoeducation Resources
    Chapter 6 Online Nanoeducation Resources Sidney R. Cohen, Ron Blonder, Shelley Rap, and Jack Barokas Abstract The internet has influenced all aspects of modern society, yet likely none more than education—opening new possibilities for how, where, and when we learn. Nanoscience and nanotechnology have developed over a similar time frame as the rapid growth of the internet and thus the use of the internet for nanoscience education serves as an interesting paradigm for internet-enabled education in general. In this chapter we give an overview of use of internet in nanoeducation, first in terms of available resources, then by describing the technological, philo- sophical, and pedagogical approaches. In order to illustrate the concepts, we describe as example a for-credit nanoscience curriculum which the authors devel- oped recently as part of an international team. 6.1 Introduction and Background The nature and emphasis of education in formal pedagogical frameworks as well as informal learning has been irreversibly impacted by the world-wide web and other rapidly changing technologies. Online resources have become a major source of information and knowledge, replacing texts and face-to-face (F2F) traditional courses. In the past decade, complete course materials have been made public, ranging from uploaded lecture notes to full video recorded class presentations. Various degrees of interactivity have been implemented in the different formats [1]. Whether it is medical assays, materials, or devices, nanotechnology has firmly rooted itself in our modern lives. In order to meet the growing need for scientists, engineers, and technicians to service and further develop this trend, the educational system must provide suitable training [2].

  • Abstract Book
    Plenary Lecture 1 Nanotechnology Path to Sustainable Society Mihail Roco (National Science Foundation and National Nanotechnology Initiative) Abstract: Nanoscale science and engineering supports a foundational technology with implications on sustainability of economy, environment and overall societal development. Special challenges are balanced, equitable and safe affirmation of the technology. By establishing controlled synthesis and processing of matter at the nanoscale, nanotechnology would require fewer amounts of materials, water, and energy; and with the high degree of precision in nanomanufacturing we are generating less pollution for the same functionality. This presentation will focus on evolution of priorities since 2000. The long-view of nanotechnology development has three stages, each dominated by a different focus: phenomenological basics and synthesis of nanocomponents (2000-2010), nanosystem integration by design for fundamentally new products (2010-2020), and creation of new technology platforms based on new nanosystem architectures (2020-2030)(www.wtec.org/nano2/). Such development raises significant sustainability opportunities and challenges. Nanoscale science and engineering is expected to converge with biotechnology, information technology, cognitive technologies and other knowledge and technology domains resulting in an increase of the complexity and uncertainty of the secondary effects (“Converging Knowledge, Technology and Society: Beyond Nano-Bio-Info-Cognitive Technologies”, Springer 2013, www.wtec.org/NBIC2-Report/).

  • The Seventh Annual Emerging Information and Technology Conference
    The Seventh Annual Emerging Information And Technology Conference Nanotechnology, System-on-Chip, Bioinformatics & Systems Biology, C4I, Emerging Energy Technology, AABF Workshops August 9 – August 10 (Thursday, Friday), 2007 Friend Center, Princeton University Princeton, New Jersey, U.S.A. In Memoriam EITC/AABF (Asian American Business Forum) advisory board member, the conference co-organizer of EITC-2007, and founding partner for PBI Tech Partners, Mr. Pao-Chien (Daniel) Di, passed away unexpectedly on Thursday, July 12, 2007 at his home in Monroe, New Jersey. He was 49. Born and raised in Taiwan, Daniel received his graduate degree in electric engineering in US in 1984. During the early part of his career, he worked for many prestigious information technology companies. His keen sense of business advanced him to VP of operation and business development for Foxconn in 2001-the turning point of his late career toward business, finance and investments. He was an amazing person and loved learning new things. After obtaining his EMBA degree from Wharton School at U. Penn, he enrolled himself into Stern Business School at NYU. Daniel enjoyed assisting others through his personal connections. Born with great leadership, he used his influential power to help change the world around him. Much of his spare time was dedicated to the Chinese community services. He was the principal of a Chinese school and board member and chairman for many non-profit organizations. This, however, was only the prologue to his great vision: he wished to see more of the Chinese community to get involved in the public service and infuse more political influence at the state and federal levels.
