In this article, I consider the historical stages of development of nanotechnology in Russia as well as the political framework for this. It is shown that early federal nanotechnology programs in Russia date back to the 1990s and that since the mid-2000s, nanotechnology has attracted the increasing attention of government. I characterize the…

Background and purpose: This study investigated Indonesian and Japanese senior high-school students' understanding of electrochemistry concepts. Sample: The questionnaire was administered to 244 Indonesian and 189 Japanese public senior high-school students. Design and methods: An 18-item multiple-choice questionnaire relating to five conceptual…

Strong societal requirements and consumer acceptance are the driving force of nanotechnology development. The necessity for qualified experts and strong demand on education in the multi-, trans- and interdisciplinary field of nanotechnology is a logical consequence of this driving force. There is the need for a comprehensive national…

As part of an outreach program, we integrated chemistry apps with blogging to enhance the learning experience of students in and outside the classroom. Our outreach program involved college mentors who participated in the development and implementation of chemistry lessons alongside the classroom teacher. Three technology-rich modules that focused…

A clarification of concepts and a comparative analysis of chirality as a consequence of stereogenic center and axes are provided by considering the different possibilities for the archetypical molecule Cabcd. The key difference between Cabcd and abC=C=Ccd and, by extension, between molecules incorporating a stereogenic axis, is in the number of…

Compares the differences in coverage and utility of three substructure databases--Chemical Abstracts, Index Chemicus, and Chemical Information System's Nomenclature Search System. The differences between Chemical Abstracts with two different vendors--STN International and Questel--are described and a summary guide for choosing between databases is…

The study examines the effectiveness of visually enhanced instruction that emphasizes molecular representations. Instructional conditions were specified in terms of the visual elaboration level (static and dynamic) and the presentation mode (whole class and individual). Fifty-two eighth graders (age range 14-15 years) participated in one of the…

The objective of this study was to examine middle school students' developing understanding of the nature of matter and to compare middle school students' ideas to those of elementary schools students, as was done by Nakhleh and Samarapungavan ["J Res Sci Teach" 36(7):777-805, 1999]. Nine middle school students were interviewed using a scripted,…

Researchers in the field of bioinformatics have developed a number of analytical programs and databases that are increasingly important for advancing biological research. Because bioinformatics programs are used to analyze, visualize, and/or compare biological data, it is likely that the use of these programs will have a positive impact on biology…
