Globalization at the nano frontier: The future of nanotechnology policy in the United States, China, and India

The field of nanotechnology offers the possibility of transforming the international science and technology (S&T) policy landscape and making a significant impact on the direction of research and development for a wide range of nations and companies. Nanotechnology endeavors in the United States, China, and India remain some of the most interesting because of the opportunities and challenges this field poses for future competition and collaboration between these three nations. This paper examines how nanotechnology will raise new science and policy questions—and lead to new strategic linkages—that will have a major impact on the futures of these nations for decades to come. Then the paper analyzes and compares the current state of nanotechnology in these three countries, discusses some of the main drivers of collaboration, investigates current and potential uncertainties associated with nanotechnology, and offers policy suggestions on ways that these difficulties may be addressed.

Winds are from Venus, mountains are from Mars: Science fiction in chemical engineering education

In an elective course recently created at Simón Bolívar University, Chemical Engineering students are encouraged to apply their previously acquired knowledge of thermodynamics, transport phenomena and other core subjects to the analysis and solution of problems drawn from science fiction works. We present a brief outline of the course contents, and describe two case studies that illustrate the general approach. The first example deals with the sublimation of carbon dioxide in Mars, and provides the basis for a discussion of the thermodynamics of phase transitions, the differences between water ice and dry ice, and the phenomenon of surface melting. The second example involves the thermal separation of strong winds in Venus, and is used to develop a simplified model of the Ranque–Hilsch vortex tube that helps understand its working principles, limitations and differences with the equivalent but physically impossible action of Maxwell's demon. In both cases, the science fiction narratives are concluded to be unrealistic, either theoretically unsound or based on inaccurate information.

Gold Medal Award for life achievement in the science of psychology.

The 2001 Gold Medal Award for Life Achievement in the Science of Psychology was awarded to R. Duncan Luce. He was cited for distinguished and influential mathematical modeling in the behavioral and social sciences. His noteworthy contributions include the concept of semiorders; choice axiom; conjoint measurement; axiomatic measurement with application to psychology, modeling response time, and generalizations of physical dimensional analysis. He is regarded as one of the most important mathematical psychologists of the past five decades. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

Carbon Nanotubes and Nanohorn Hybrid Composite Buckypaper as Microporous Layer for Proton Exchange Membrane Fuel Cell

In the present work, carbon nanotubes (CNT) and CNT‐carbon nanohorns (CNH) (0, 30, 50, 70 and 100 wt.% CNH) composite Buckypapers (BPs) were fabricated using vacuum filtration technique. Structure and property relation of composite BPs were studied using scanning electron microscope, four probe technique, BET surface area and contact angle measurements. Properties such as electrical conductivity, hydrophobic nature and microstructure of CNT‐30 wt.% CNH composite BP are superior to other composite BP. Hence, CNT‐30 wt.% CNH composite BP is chosen as a microporous layer (MPL) for PEMFCs and tested in fuel cell testing fixture. Polarization studies reveal that the cells performance with composite BPs is comparable with SGL‐MPL based cell. Hydrogen pumping and polarization studies of the cells confirms that composite BPs act as a good MPL at anode as well as cathode at 0.4 to 0.8 V. Hence, CNT‐CNH composite BPs are potential candidates for PEMFC applications.     

从整体的地景综合到跨学科的地景管理

"地景"一词的内涵是很丰富的,且这个概念本身即蕴含着一种固有的整体观。早在文艺复兴时期,欧洲就已经产生了若干种相异的安排和布置地景的方式,不同的方式运用着不同的观念和方法。我们可以将其划分为三类,第一是自然科学,其中地景生态学起着主导作用;第二是人文科学,其中多运用历史地理、历史生态学、人文主义和符号学等手法的途径;第三是应用科学,主要是指地景设计、建筑设计与规划领域。每一分类都有助于人们深入理解地景。本文对不同类别的地景研究进行比较,但直到目前它们也还没有形成共同的观念、相同的目标和统一的描述语言,至于如何在"跨学科"的地景科学的框架下实现具有创造力的综合创新也就更无法明确。但必须明确的是,对于地景,无论是管理还是规划,我们面对的都是一块相同的土地,是面对同一对象来解决各种各样的问题。那么,这个过程就必须采取综合的方法,就不可避免地要进行跨学科的合作。
