Diamondoid Mechanosynthesis Prepared for the International Technology Roadmap for Productive Nanosystems
IMM White Paper Scanning Probe Diamondoid Mechanosynthesis Prepared for the International Technology Roadmap for Productive Nanosystems 1 August 2007 D.R. Forrest, R. A. Freitas, N. Jacobstein One proposed pathway to atomically precise manufacturing is scanning probe diamondoid mechanosynthesis (DMS): employing scanning probe technology for positional control in combination with novel reactive tips to fabricate atomically-precise diamondoid components under positional control. This pathway has its roots in the 1986 book Engines of Creation, in which the manufacture of diamondoid parts was proposed as a long-term objective by Drexler [1], and in the 1989 demonstration by Donald Eigler at IBM that individual atoms could be manipulated by a scanning tunelling microscope [2]. The proposed DMS-based pathway would skip the intermediate enabling technologies proposed by Drexler [1a, 1b, 1c] (these begin with polymeric structures and solution-phase synthesis) and would instead move toward advanced DMS in a more direct way. Although DMS has not yet been realized experimentally, there is a strong base of experimental results and theory that indicate it can be achieved in the near term. • Scanning probe positional assembly with single atoms has been successfully demonstrated in by different research groups for Fe and CO on Ag, Si on Si, and H on Si and CNHCH3. • Theoretical treatments of tip reactions show that carbon dimers1 can be transferred to diamond surfaces with high fidelity. • A study on tip design showed that many variations on a design turn out to be suitable for accurate carbon dimer placement. Therefore, efforts can be focused on the variations of tooltips of many kinds that are easier to synthesize. -

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. -
Industrial Ecology: a New Perspective on the Future of the Industrial System
Industrial Ecology: a new perspective on the future of the industrial system (President's lecture, Assemblée annuelle de la Société Suisse de Pneumologie, Genève, 30 mars 2001.) Suren Erkman Institute for Communication and Analysis of Science and Technology (ICAST), P. O. Box 474, CH-1211 Geneva 12, Switzerland Introduction Industrial ecology? A surprising, intriguing expression that immediately draws our attention. The spontaneous reaction is that «industrial ecology» is a contradiction in terms, something of an oxymoron, like «obscure clarity» or «burning ice». Why this reflex? Probably because we are used to considering the industrial system as isolated from the Biosphere, with factories and cities on one side and nature on the other, the problem consisting in trying to minimize the impact of the industrial system on what is «outside» of it: its surroundings, the «environment». As early as the 1950’s, this end-of-pipe angle was the one adopted by ecologists, whose first serious studies focused on the consequences of the various forms of pollution on nature. In this perspective on the industrial system, human industrial activity as such remained outside of the field of research. Industrial ecology explores the opposite assumption: the industrial system can be seen as a certain kind of ecosystem. After all, the industrial system, just as natural ecosystems, can be described as a particular distribution of materials, energy, and information flows. Furthermore, the entire industrial system relies on resources and services provided by the Biosphere, from which it cannot be dissociated. (It should be specified that .«industrial», in the context of industrial ecology, refers to all human activities occurring within the modern technological society. -

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. -

Honorary Doctor of Science Professor BAI Chunli Citation written and delivered by Professor LIU Chain-tsuan Chancellor: It is my great honour to present to you Professor Bai Chunli, President of the Chinese Academy of Sciences (CAS), who is not only one of China’s most eminent scientists and an outstanding nanotechnological pioneer but a highly accomplished science and technology leader. Born in 1953 in the city of Dandong, Liaoning Province, Professor Bai received his bachelor’s degree from Peking University in 1978. He continued his studies at the Chinese Academy of Science’s Institute of Chemistry, where he received his MSc and PhD degrees in 1981 and 1985 respectively. From 1985 to 1987, he undertook postdoctoral research at the famous California Institute of Technology in the United States, after which he returned to China to join the Academy. From then until now he has been conducting research and providing leadership there, with the exception of 1991-1992 when he was a visiting professor at Tohoku University in Japan. He was promoted to the CAS Vice-Presidency in 1996, was elected to membership of the Academy in 1997, and has been President of its Graduate School since 2001. He was promoted to CAS Executive Vice-President in 2004, then CAS President and Chairman of the Presidium of the Academic Divisions of the CAS in 2011. With a big honour, he was selected as the new President of the Academy of Sciences for the Developing World in September this year. At this point please allow me to offer a brief review of the development of scientific education in contemporary China, since this forms the background to Professor Bai’s exceptional career. -
