Presentation Transcript

  1. World wide web • Information on computers linked together • Browser (Netscape or IExplorer or Opera) • Hyper Text Markup Language (HTML, XML) • Hypertext (non-linear progress) • Clickable links; images, sound, video, etc. • Search engines (Alta Vista, Google, etc.) • Chemistry? • Molecules via Java, Chime, VRML

  2. Beginnings ... • Chemistry Department homepage URL • http://www.nuigalway.ie/chem/chemdept.htm • Links to other documents • Local, national, international • Colour change // Mouse right-button • Search engines • Alta Vista or Google or Lycos or HotBot, etc. • Search strategies

  3. Local data sources • People, courses, seminars, research, etc. • Campus map • Administration • Research guide • Hardiman Library • OPAC • Web of Science

  4. International sources of data • Chemistry Mark Winter at Univ. of Sheffield • http://www.ChemDex.org • MSDS Material Data Safety Sheets • http://siri.org/msds/ • NIST Webbook • http:// webbook.nist.gov/chemistry/ • Mass spectrometry on the Internet • http://tswww.cc.emory.edu/~kmurray/

  5. Molecular representation • Chime (MDL Information Systems) • Chime plug-in, from www.mdli.com/downloads/ • Example: http://c4.cabrillo.cc.ca.us/ • The plug-in displays 2&3D molecules directly within a web page and works with most Browsers (but not Internet Explorer!) on Windows and Macintosh. The molecules in the web page are "live," meaning they are not just pictures, but chemical structures that can be rotated, reformatted, and saved in various file formats. • Anyone with a knowledge of HTML can add structures to their research projects, tutorials, newsletters, journals, and presentations published across an intranet or the Internet.

  6. Chemsymphony//JMol • Lite version from www.cherwell.com • Example: /chem/chemsym.htm • Java applet (Best example: Jmol) • An applet is a program written in the Java programming language that can be included in an HTML page, much in the same way an image is included. When you use a Java technology-enabled browser to view a page that contains an applet, the applet's code is transferred to your system and executed by the browser. See our ‘official webpage’ • http://www.nuigalway.ie/faculties_departments/chemistry/

  7. VRML • Virtual Reality Modeling Language is a platform-independent file format for sharing 3D worlds on the Web. VRML worlds can be interactive and animated, and can include embedded hyperlinks to other Web documents. • Example: “Molecule of the month” • www.bris.ac.uk/Depts/Chemistry/MOTM/ or • ws05.pc.chemie.th-darmstadt.de/vrml/ • www.indiana.edu/~cheminfo/mvts.html

  8. “WebActive Chemistry”? • Two-way interaction • www.ch.ic.ac.uk/aptonge/mdl/ • www.chem.cmu.edu/djsoft/Java/ • Remote usage (client-server) • Virtual chemistry • Lectures • www.smps.ntu.edu.au/modules/mod3/
