Chemistry and SMIL
by Rzepa, Henry 06 Mar '00

06 Mar '00

SMIL is an XML language for Synchronised Multimedia Integration. Put at its simplest, its a very basic HTML (really XHTML) with time codes built in. As with any good markup language, all you really need to write it is a text editor (although custom programs for the purpose do exist). To demonstrate a little of what it can be used for, take a look at http://www.ch.ic.ac.uk/video/barrett/barrett_qt.smil This URL must be entered into a SMIL player. Currently, these are dedicated programs (rather than Web browsers) such as Quicktime Player, RealPlayer or Windows Media player (links for getting these at http://www.ch.ic.ac.uk/video/ ) Using Quicktime 4.1 (earlier versions do not work), enter the above URL. You can also try http://www.ch.ic.ac.uk/video/barrett/barrett_rp.smil in RealPlayer etc. Since the best way of learning is by example, I include the entire source code below. As with any new technology, there are limitations. Thus early in the Web, chemical MIME types were used to transclude chemical content, and chemical plugins and Java components were developed for the purpose. Media players such as those noted above do NOT support such chemical content. It appears that one cannot gain access to the chemical MIME types by invoking SMIL in a browser either (Quicktime plugin does not appear to support the SMIL media type). The solution here is to use the power of XML: watch this space for a demo shortly. ====================================================== <smil> <head> <meta name="Title" content="Novel Polymers, Novel Linkers and Novel Transformations in Parallel Synthesis" /> <meta name="Author" content="AGM Barrett and HS Rzepa" /> <meta name="Description" content="Combinatorial Chemistry" /> <meta name="Copyright" content="(c) AGM Barrett and HS Rzepa" /> <meta name="Base" content=""/> <layout> <root-layout id="1.smil" width="690" height="360" background-color="black" title="Barrett" /> <region id="movie" left="0" top="0" width="128" height="96" z-index="1" background-color="black" fit="fill" /> <region id="slide" left="150" top="0" width="540" height="360" z-index="1" background-color="black" fit="fill" /> <region id="search" left="0" top="160" width="140" height="50" z-index="1" background-color="black" /> <region id="text" left="0" top="210" width="140" height="300" z-index="1" background-color="black" /> </layout> </head> <body> <par> <img src="images/0.gif" region="slide" begin="1:24m" end="3:03m" /> <img src="images/1.gif" region="slide" begin="3:05m" end="6:10m" /> <img src="images/2.gif" region="slide" begin="6:12m" end="7:52m" /> <img src="images/3.gif" region="slide" begin="7:53m" end="9:35m" /> <img src="images/4.gif" region="slide" begin="9:36m" end="11:12m" /> <img src="images/5.gif" region="slide" begin="11:13m" end="13:46" /> <img src="images/6.gif" region="slide" begin="13:47m" end="17:50m" /> <img src="images/7.gif" region="slide" begin="17:51m" end="18:21m" /> <img src="images/8.gif" region="slide" begin="18:23m" end="19:54m" /> <img src="images/9.gif" region="slide" begin="19:55m" end="20:20m" /> <img src="images/10.gif" region="slide" begin="20:21m" end="20:59m" /> <img src="images/11.gif" region="slide" begin="21:00m" end="21:23m" /> <img src="images/12.gif" region="slide" begin="21:24m" end="21:57m" /> <img src="images/13.gif" region="slide" begin="21:58m" end="22:38m" /> <img src="images/14.gif" region="slide" begin="22:39m" end="23:02m" /> <img src="images/15.gif" region="slide" begin="23:03m" end="23:45m" /> <img src="images/16.gif" region="slide" begin="23:46m" end="25:56m" /> <img src="images/17.gif" region="slide" begin="25:57m" end="27:20m" /> <img src="images/18.gif" region="slide" begin="27:21m" end="29:41m" /> <img src="images/19.gif" region="slide" begin="27:42m" end="30:19m" /> <img src="images/20.gif" region="slide" begin="30:20m" end="32:48m" /> <img src="images/21.gif" region="slide" begin="32:49m" end="34:14m" /> <img src="images/22.gif" region="slide" begin="34:15m" end="35:20m" /> <img src="images/23.gif" region="slide" begin="35:21m" end="36:26m" /> <img src="images/24.gif" region="slide" begin="36:27m" end="37:18m" /> <img src="images/25.gif" region="slide" begin="37:19m" end="38:26m" /> <img src="images/26.gif" region="slide" begin="38:27m" end="38:47m" /> <img src="images/27.gif" region="slide" begin="38:48m" end="39:25m" /> <img src="images/28.gif" region="slide" begin="39:26m" end="40:12m" /> <img src="images/29.gif" region="slide" begin="40:13m" end="42:10m" /> <img src="images/30.gif" region="slide" begin="42:11m" end="42:59m" /> <img src="images/31.gif" region="slide" begin="43:00m" end="44:07m" /> <img src="images/32.gif" region="slide" begin="44:08m" end="45:20m" /> <img src="images/33.gif" region="slide" begin="45:21m" end="45:51m" /> <img src="images/34.gif" region="slide" begin="45:52m" /> <animation src="barrett.mov" region="movie" begin="0:00m" /> <a href="http://www.ch.ic.ac.uk/video/barrett/jobjects/qascript.htm" ><text src="2.txt" type="text/plain" region="search" begin="0:00m" /></a> <text src="date.txt" type="text/plain" region="text" begin="0:00m" /> </par> </body> </smil> -- Henry Rzepa.

Software/Database for Review
by Dr. Stephen R. Heller 23 Feb '00

23 Feb '00

February 22, 2000 Subject: Computer Software/Database for Review As the Software Review Editor for the ACS Journal of Chemical Information and Computer Science (JCICS) I often get software for review in the journal. I have one (1) new web-based software/database product. I am looking for someone who is willing to review this product on the web. The review should be completed in 1-3 months. The length of the review is 4-10 double spaced typed pages. Sample reviews can be found in most of the recent issues of JCICS. Please try to give me some (short) reason to choose you over another person. I have tried this approach for about the past five years and it is working reasonably well. (REMINDER: For those who haven't finished your reviews of software sent months and months ago, this last sentence does not apply to you!) As a result, I am continuing this new method to find reviewers using this e-mail/user group system. I reserve the right to abandon this if it is a problem, or inappropriate. I will not notify people if I have found a reviewer. If you don't hear from me within a few days I have chosen someone else to review the particular package. As I get many, many, (too many) replies to this message, please do not respond after 25 February 2000 (Friday), as I am sure the software will be gone by then. I can be reached on Internet (STEVE(a)HELLERS.COM) This is a new e-mail address. Steve Heller The package I now have is: ACD/I-Lab, the Interactive Laboratory is an online service including systematic naming generation, NMR and physicochemical prediction, and online database searching by structure and substructure. The person doing the review will be given a few hundred dollars credit to to access www.acdlabs.com/ilab to try it out and then write the review. While it is an online service but comes connected to the FREE Chemsketch interface for people to connect to. The reviewer would need to download CHemsketch to connect or use the Java applet. The reviewer MUST be using a very recent version of Internet Explorer or Netscape Navigator. Stephen R. Heller, Ph. D. Guest Researcher NIST/SRD, Mail Stop: 820/113 100 Bureau Drive 820 Diamond Avenue, Room 101 Gaithersburg, MD 20899-2310 USA Phone: 301-975-3338 FAX: 301-926-0416 E-mail: steve(a)hellers.com WWW: www.hellers.com/~steve -------------------------------------------------- As a member of the Organizing Committee, I invite you to attend Chemistry & the Internet - ChemInt2000; September 23-26, 2000; Washington, DC. http://www.chemint.org chemweb: A list for Chemical Applications of the Internet.

WebElements Periodic Table Scholar Edition
by Mark Winter 21 Feb '00

21 Feb '00

Dear colleagues **Apologies if you get this more than once** WebElements Periodic Table Scholar Edition This is a request for help and comment. I'm pleased to announce the trial version of the scholar edition of WebElements. This version will be useful to students at university and school. For a few days, the only way in is via: http://www.webelements.com/webelements/scholar/ At this early stage, the scholar edition is a selected subset of the full version of WebElements. Hopefully students will find it easier to navigate around and less confusing than the full version. In time, new material and features will appear written especially for the target audience. I'd appreciate any comments you might care to make via the online feedback forms on the new edition before I make it available to everyone. In particular: Are there data that I've left out that should be left in? Are there data that I've left in that should be left out? Is the navigation easy? Do the features work? Are the inline quiz questions useful or distracting? What else is needed/not needed? Thanks in advance for the help!

SVG and Chemistry
by Rzepa, Henry 20 Feb '00

20 Feb '00

You might find http://www.ch.ic.ac.uk/svg/ interesting to compare with the conventional "GIF" image format for illustrating chemistry on the Web. For much of chemistry, I believe the XML based SVG is a substantial improvement over bitmaps. The full features of the SVG specification which include animation, printability, etc seems full of potential in chemistry. Henry Rzepa.

Research talks by eminent scientists
by Rzepa, Henry 17 Feb '00

17 Feb '00

Members of this list might be interested in our collection of video/chemical materials at http://www.ch.ic.ac.uk/video/ Here, we have offered archive video materials from our Institute, relating to members, past and present of our department, and two very recent research seminars that were recorded here. One talk (Charles Rees) is linked to 3D models of the molecules, for which you will need a plugin such as Chime or Chem3D. We expect to add to this collection on a regular basis. Legal bit: this material is all copyrighted, and no unauthorised use for republication is permitted. I believe other similar collections exist, although I am not aware of any good index of such materials. If anyone knows of similar projects at their own institute, please let this list or me know! If anyone wants details of how the stuff was made (and how much it cost!) please contact me. -- Henry Rzepa. +44 (0)20 7594 5774 (Office) +44 (0)20 7594 5804 (Fax) Dept.
