Report of the 2012 NNI Workshop on Regional, State & Local Initiatives in Nanotechnology iii Preface This report on Regional, State, and Local (RSL) Initiatives in Nanotechnology is the result of a workshop convened 1–2 May 2012 in Portland, Oregon, by the Nanoscale Science, Engineering, and Technology (NSET) Subcommittee of the National Science and Technology Council. The report was made possible with the help of the NSET Subcommittee’s Nanomanufacturing, Industry Liaison, and Innovation (NILI) Working Group and with staff support from the National Nanotechnology Coordination Office (NNCO). The workshop is part of the NSET Subcommittee’s long-range planning efforts for the National Nanotechnology Initiative (NNI), the multi-agency Federal nanotechnology program. The NNI is driven by long-term goals based on broad community input, in part received through workshops such as this one. The NNI seeks to accelerate the research, development, and deployment of nanotechnology to address national needs, enhance our nation’s economy, and improve the quality of life in the United States and around the world through the coordination of activities and programs across the Federal Government. The NNI’s reports are the result of an ongoing series of workshops organized by the NSET Subcommittee to inform the professional communities as well as the various agencies and organizations that have responsibilities for coordinating, implementing, and guiding the NNI. The goal of the 2012 NNI Workshop on RSL Initiatives in Nanotechnology was to improve the outcomes of nanotechnology research, education, and business activities undertaken by U.S. organizations working to advance nanotechnology, such as small and large businesses, universities, research and education foundations, industry groups, and nongovernmental organizations. The strategy for reaching this goal is to exploit synergies between the various initiatives, promote sharing of information and resources, and develop ongoing mechanisms for relevant interactions. Specific objectives of the workshop are outlined in the Executive Summary and in Chapter 1. On behalf of the NSET Subcommittee, we thank Skip Rung of ONAMI and Jim Kadtke of NNCO for taking the lead in organizing and in co-chairing the workshop. Thanks are also due to the NILI Working Group for leading the planning effort on behalf of the NSET Subcommittee, and to the members of the workshop organizing committee (listed on the facing page). We also thank all the speakers and participants for their time and efforts to join the workshop and to make their individual contributions to the workshop discussions and to this report. We offer special thanks

  • 2 Scalability of the Channel Capacity of Electromagnetic Nano- Networks 10 2.1 Introduction
    Exploring the Scalability Limits of Communication Networks at the Nanoscale Thesis submitted in partial fulfillment of the requirements for the degree of Master in Computer Architecture, Networks and Systems by Ignacio Llatser Mart´ı Advisors: Dr. Eduard Alarc´onCot Dr. Albert Cabellos-Aparicio 2011 Nanonetworking Center in Catalunya (N3Cat) Universitat Polit`ecnicade Catalunya Abstract Nanonetworks, the interconnection of nanomachines, will greatly expand the range of applications of nanotechnology, bringing new opportunities in di- verse fields. Following preliminary studies, two paradigms that promise the re- alization of nanonetworks have emerged: molecular communication and nano- electromagnetic communication. In this thesis, we study the scalability of communication networks when their size shrinks to the nanoscale. In particular, we aim to analyze how the performance metrics of nanonetworks, such as the channel attenuation or the propagation delay, scale as the size of the network is reduced. In the case of nano-electromagnetic communication, we focus on the scal- ability of the channel capacity. Our quantitative results show that due to quantum effects appearing at the nanoscale, the transmission range of nanoma- chines is higher than expected. Based on these results, we derive guidelines regarding how network parameters, such as the transmitted power, need to scale in order to keep the network feasible. In molecular communication, we concentrate in a scenario of short-range molecular signaling governed by Fick's laws of diffusion. We characterize its physical channel and we derive analytical expressions for some key perfor- mance metrics from the communication standpoint, which are validated by means of simulation. We also show the differences in the scalability of the obtained metrics with respect to their equivalent in wireless electromagnetic communication.

  • Applications of Molecular Communications to Medicine: a Survey
    Applications of molecular communications to medicine: a survey L. Felicetti, M. Femminella, G. Reali*, P. Liò Abstract In recent years, progresses in nanotechnology have established the foundations for implementing nanomachines capable of carrying out simple but significant tasks. Under this stimulus, researchers have been proposing various solutions for realizing nanoscale communications, considering both electromagnetic and biological communications. Their aim is to extend the capabilities of nanodevices, so as to enable the execution of more complex tasks by means of mutual coordination, achievable through communications. However, although most of these proposals show how devices can communicate at the nanoscales, they leave in the background specific applications of these new technologies. Thus, this paper shows an overview of the actual and potential applications that can rely on a specific class of such communications techniques, commonly referred to as molecular communications. In particular, we focus on health-related applications. This decision is due to the rapidly increasing interests of research communities and companies to minimally invasive, biocompatible, and targeted health-care solutions. Molecular communication techniques have actually the potentials of becoming the main technology for implementing advanced medical solution. Hence, in this paper we provide a taxonomy of potential applications, illustrate them in some details, along with the existing open challenges for them to be actually deployed, and draw future perspectives. Keywords: molecular communications, nanomedicine, targeted scope, interfacing, control methods L. Felicetti, M. Femminella, and G.

In this article, we investigate the effect of the one of the most important fabrication parameters, pulse frequency, for optimizing supercapacitor efficiency. A series of coin cell batteries with laser-induced electrodes was fabricated; the effect of pulse frequency on oxidation levels and material properties was studied using both experimental and theoretical analysis. Also, detailed electrochemical tests including cyclic voltammetry (CV), charge/discharge, and electrochemical impedance spectroscopy (EIS) were conducted to better understand the effect of pulse frequency on the electrochemical performance of the fabricated devices.

  • Energy Harvesting in Electromagnetic Nanonetworks
    1 Energy Harvesting in Electromagnetic Nanonetworks Shahram Mohrehkesh1, Michele C. Weigle2, and Sajal K. Das3 1 Department of Computer and Information Sciences, Temple University, Philadelphia, PA 2Department of Computer Science, Old Dominion University, Norfolk, VA 3Department of Computer Science, Missouri University of Science and Technology, Rolla, MO [email protected], [email protected], [email protected] Abstract—This paper reviews the processes, issues, and chal- lenges in energy harvesting in an electromagnetic nanonetwork, composed of nanonodes that are nanometers to micrometers in size. Each nanonode harvests the energy required for its oper- ations, such as processing and communication through ambient energy sources such as fuel or vibration. To create a nanonetwork, unique characteristics of nanonodes such as nanoscale size and communication technology should be considered along the energy harvesting process. We introduce energy harvesting issues and challenges in nanonetwork related to the design and performance evaluation of a nanonetwork in terms of throughput, delay and the utilization of harvested energy. Finally, we discuss open issues in the realization of energy harvesting nanonetworks. I.
