JMOL CRYSTALLINE SOLID SOFTWARE
Despite its limitations, Chime formed the basis of many tutorials and web-based educational software tools.Ģ. Educators with a bit of web-development experience could for the first time make available to a wider audience interactive molecular structure-annotated texts. The Chime plug-in was essentially RasMol for the web with a broader focus that included calculated structures of small molecules. With the development of the web during the 1990s came the second phase of this process, spearheaded by the release of the Chime Netscape plug-in in 1996. One of the important features introduced in RasMol was the capability of scripting, thus allowing for a `guided tour' approach to exploration of crystal structures and opening entirely new possibilities for education. Focused as it was on biomolecular structures, RasMol represented a major advance in the area of biochemistry and molecular biology. This program, probably more than any other, brought the world of crystal structure into the hands of educators. The Jmol applet represents the third stage of an evolutionary process that started with the development of RasMol (Sayle & Milner-White, 1995 ) in 1989. We have just recently begun to learn how it can be used to enhance student understanding of the principles of crystallography and appreciation of the beauty of symmetry. The Jmol molecular visualization applet ( Jmol, 2010 ) is leading the way in this shift. The shift is away from licensed profit-driven software with periodic updates to openly available software with rapid community-based `immediate' development goals. The paradigm shift of the 21st century is away from monolithic programs that are designed to do a specific task on a specific platform in a specific subdiscipline of science and toward tools that are more modular, flexible and useful in a broad interdisciplinary context. These programs – web-based, open-source and platform-independent – combine features of rapid development, expert communities and widely accessible databases with the power of the web to communicate features of molecular and crystallographic structure in creative and artistic ways that could not have been imagined in 1965. This paper focuses on a new paradigm of computer program that aims to revolutionize the area of visualization in chemical education again, particularly in the area of crystallography. In addition, specialized software and web-based tutorials specifically targeting fundamental concepts of crystallography and molecular symmetry are now available (Cass & Rzepa, 2005 Harwood & Korkmaz, 2005 Johnston, 2005, 2008 Charistos et al., 2005 Kastner et al., 2000 ). While developed primarily for research purposes, these programs have found utility in the area of education as well, as noted in recent symposia at national American Chemical Society meetings (Kantardjieff, 2005 Battle et al., 2009 ). Since then, personal computing power has increased immensely, and a number of computer programs have been introduced that allow real-time interactive construction of crystals ( CrystalMaker, 2009 Shape, 2009 ) and exploration of molecular structure and bonding in the context of databases. The introduction of ORTEP (Johnson, 1965 ) over 40 years ago made possible for the first time a ready two-dimensional projection of the three-dimensional atomic world of crystals and ushered in a revolution in molecular visualization. It goes without saying that visualization is important in the area of crystallography. Introduction – crystallographic visualization

We also provide many author benefits, such as free PDFs, a liberal copyright policy, special discounts on Elsevier publications and much more. Glass, amorphous, non-crystalline, vitreous, glass-ceramic, glass-matrix composite, glass-forming liquid In the case of Letters, a compelling case must also be made for expedited handling. In all cases, the papers must demonstrate both novelty and importance to the field by way of significant advances in understanding or application of non-crystalline materials. Papers on partially glassy materials, such as glass-ceramics and glass-matrix composites, and papers involving the liquid state are also included in so far as the properties of the liquid are relevant for glass formation. The Journal of Non-Crystalline Solids publishes review articles, research papers, and Letters to the Editor on amorphous and glassy materials, including inorganic, organic, polymeric, hybrid, and metallic systems. To submit to Journal of Non-Crystalline Solids: X visit. Journal of Non-Crystalline Solids has an open access companion journal Journal of Non-Crystalline Solids: X which has the same aims and scope, editorial board and peer-review process.
