Molecular manufacturing is a method conceived for the processing and rearrangement of atoms to fabricate custom products. It would rely on the use of a large number of molecular electro-mechanical subsystems working in parallel and using commonly available chemicals. Built to atomic specification, the products would exhibit order-of-magnitude improvements in strength, toughness, speed, and efficiency, and be of high quality and low cost. In Part 1: Technical Issues, I pro- vide an overview of molecular nanotechnology and explore ways in which molecu- lar manufacturing could be applied to improve textile products. -
Designing a Nanoelectronic Circuit to Control a Millimeter-Scale Walking Robot

W809 Approved for public release; distribution unlimited. Copyright © 2004 by The MITRE Corporation. All rights reserved. Gates, Alexander Abstract A novel nanoelectronic digital logic circuit was designed to control a millimeter-scale walking robot using a nanowire circuit architecture. This nanoelectronic circuit has a number of benefits, including extremely small size and relatively low power consumption. These make it ideal for controlling microelectromechnical systems (MEMS), such as a millirobot. Simulations were performed using a SPICE circuit simulator, and unique device models were constructed in this research to assess the function and integrity of the nanoelectronic circuit’s output. It was determined that the output signals predicted for the nanocircuit by these simulations meet the requirements of the design, although there was a minor signal stability issue. A proposal is made to ameliorate this potential problem. Based on this proposal and the results of the simulations, the nanoelectronic circuit designed in this research could be used to begin to address the broader issue of further miniaturizing circuit-micromachine systems. i Gates, Alexander I. Introduction The purpose of this paper is to describe the novel nanoelectronic digital logic circuit shown in Figure 1, which has been designed by this author to control a millimeter-scale walking robot. -

The essence of nanotechnology is to produce and manipulate well- defined structures on the nanometer scale with high accuracy. Conventional technologies based on the "top-down” approaches, such as the photolithographyic method, are difficult to continue to scale down due to real physical limitations including size of atoms, wavelengths of radiation used for lithography, and interconnect schemes. -

Metal and Semiconductor Nanoparticle Self-Assembly by G. Daniel Lilly A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy (Chemical Engineering) in The University of Michigan 2009 Doctoral Committee: Professor Nicholas A. Kotov, Chair Professor Sharon C. Glotzer Professor Xiaoqing Pan Assistant Professor Suljo Linic © G. Daniel Lilly 2009 To my wife, Michelle M. Lilly, Ph.D. To my mother and father, Nancy N. and G. Bud Lilly ii ACKNOWLEDGEMENTS I would like to thank my loving and lovely wife Michelle for her support through the process of obtaining my Ph.D. If not for her support and advice I most likely would not have finished this process. I value her as a friend and partner and am forever appreciative of her actions. I would also like to thank my parents for laying the groundwork in my life to accomplish this. They taught me the value of hard work and persistence when reaching toward your goals, and without these lessons I most likely would not have even gone to graduate school, much less finished. I am appreciative for all the help and support my fellow lab members have given me over the last five years. Former lab members Jaebeom Lee, Zhiyong Tang, Paul Podsiadlo, Bongsup Ship, Jungwoo Lee and Kevin Critchley helped teach me new lab techniques, NP synthesis and conjugation techniques, and numerous analysis procedures, and allowed me a venue to discuss my hypotheses concerning these approaches. Current lab members Meghan Cuddihy, Edward Jan, Peter Ho, Ashish Agarwal, Christine Andres, Jian Zhu, Huanan Zhang, Elizabeth Stewart, Yichun Wang, Inigo Alvarez, Shimei Xu, and Anna Fernandez aided with various collaborations, techniques, procedures, and experiences for which I am grateful. -

Advisor: Marta Fernández Regúlez Christian Pinto Gómez Academic tutor: Joan Bausells Roigé i ii Abstract The main goal of this dissertation, entitled “Directed self-assembly of block copolymers for the fabrication of nanomechanical structures”, is to demonstrate the possibility of fabricating nanomechanical functional structures by employing the directed self- assembly (DSA) of block copolymers (BCPs) as a nanopatterning tool. DSA is a bottom-up nanolithography technique based on the ability of BCPs to segregate into domains at the micro/nanoscale, and it has attracted high interest due to its inherent simplicity, high throughput, low cost and potential for sub-10 nm resolution. -

Nanotechnoscience: The End of the Beginning Bernadette Bensaude-Vincent Université Paris 1 Panthéon-Sorbonne (France) Jonathan Simon Archives Henri-Poincaré – Philosophie et Recherches sur les Sciences et les Technologies (AHP-PReST), Université de Lorraine, Université de Strasbourg, CNRS, Nancy (France) Is there still room at the bottom? The question providing the theme for the present issue of Philosophia Scientiæ is, of course, adapted from Richard Feynman’s well-known speech at the 1959 meeting of the American Physical Society. On this occasion he attracted physicists’ attention to the vast potential of working at the scale of the nanometre if not the ångström, using the catchy title: “Plenty of Room at the Bottom” [Feynman 1959]. This hookline from a famous Nobel laureate physicist served as a motto for the emerging field of nanoscience and nanotechnology (which we will here abbreviate to nanoresearch) in the early 2000s. -

Application of Molecular Simulation Techniques to the Design of Nanosystems

(2) Model and characterize a dendronized polymethacrylate carrying second generation chiral 4-aminoproline-based dendrons and a thiophene based dendronized polymer in order to explain, in basis of their structure, the extraordinary stiffness of the first and the great conductivity exhibited by the latter in previous experimental studies. (3) Study of the interactions of thiophene based conducting polymers. The interaction of these polymers with the solvent medium as well as their intermolecular interactions such as π-stacking interactions play a key role when designing new devices based on conducting polymers. (4) Exploit the intrinsic tubular geometry of natural motifs extracted from certain proteins together with the ability of π-conjugated systems to promote charge transfer to model a tubular electronic conductor based on natural peptide sequences by replacing natural amino acids by synthetic amino acids owning an aromatic side chain. (5) Study of the role played by the solvent molecules in the actuation mechanism in the molecular actuator poly(calix[4]arene bis-bithiophene) by the examination of the structure and dynamics of the dichloromethane solvent around the calix[4]arene units. (6) Investigation of the selectivity of a polythiophene functionalized with calix[4]arene nanosensor at the microscopic level which experimentally presents a great selectivity towards Na+ with respect to K+ and Li+ alkaline cations. -
