Bulletin of Science, Technology & Society Vol. 26, No. 6, December 2006, 451-462 DOI: 10.1177/0270467606295003 Copyright © 2006 Sage Publications Research in nanotechnology has advanced rapidly in recent years. Several researchers, however, warn that there is a paucity of research on the ethical, legal, and social implications of nanotechnology, and they caution that ethical reflections on nano...

Current semiconductor technology is projected to reach its physical limit in about a decade. To satisfy the ever-growing consumer desire for small, high-speed, low-power, and “all-in-one” devices, scientists and engineers are actively seeking solutions to continue technology trends into the future. Nanotechnology, with wide electronics applications, promises breakthroughs for the future. The fu...

The field of nanotechnology is growing explosively and impinging on all walks of life. This is reflected in the appearance of nanotechnology in consumer products; in March 2011, the Project on Emerging Nanotechnologies, a partnership between the Woodrow Wilson International Center for Scholars and the Pew Charitable Trusts, reported more than 1300 consumer products containing nanotechnology on ...

Nanotechnology is an up-and-coming branch of science that studies and designs materials with at least one dimension sized from 1-100 nm. These nanomaterials have unique functions at the cellular, atomic, and molecular levels. The term "nanotechnology" was first coined in 1974. Since then, it has evolved dramatically and now consists of distinct and independent scientific fields. Nanotechnology ...

This paper assesses the diffusion of nanoscience and nanotechnology in Turkey in the last decade using bibliometric and Social Network Analysis (SNA) techniques. We extracted a total of 10,062 articles and reviews from Web of Science (WoS) authored by the Turkish scientists between 2000 and 2011. We divided the data set into two 6-year periods (2000-2005 and 2006-2011). Almost three quarters (7...

The impact of international collaboration on research performance has been extensively explored over the past two decades. Most research, however, focuses on quantity and citation-based indicators. Using the turnover of keywords, this study develops an integrative approach, tracking and visualizing the shift of the research stream, and tests it within the context of U.S.–China collaboration in ...

The paper is concerned with the technological process of renovation of shafts used in industrial manufacturing for extruding of sheet material. In the classical renovation technologies, a chrome based coating is applied to the working surface of the shaft in galvanic baths. The process, however, is known to be exclusively harmful due to the waste cyanide products. In this work, we present an ad...

Reversible circuit designing is the area where researchers are focussing more and more for the generation of low loss digital system designs. Researchers are using the concept of Reversible Logic in many areas such as Nanotechnology, low loss computing, optical computing, low power CMOS design etc. Here we have proposed a novel design approach for a 2-bit binary Arithmetic Logic Unit (ALU) usin...
