Remember, the <figure> element is not necessary to display a <media> element. Use <figure> when you want to set your multimedia content apart from the surrounding text, add a title or caption, or create a numbered figure label for your media. If you just want your media to display inline, only use the <media> element.

The<Subfigure>Element

You can place two or more images within the same figure using the subfigure tag. This is useful when you have two related images that you want to display side-by-side or oneabove the other. The following CNXML snippet can be used to display two subfigures side-by-side: <figure id="figure-2" orient="horizontal"><subfigure id="subfigure-1"><title>Blue on Blue</title><media id="sub_example" alt="An envelope with a blue page"><image mime-type="image/png" src="Xenvelope-blue-on-blue.png"/><caption>Subfigure 1.</caption></media></subfigure><subfigure id="subfigure-2"><title>Orange on White</title><media id="sub_example2" alt="An envelope with a white page"><image mime-type="image/png" src="Xenvelope.png"/><caption>Subfigure 2.</caption></media></subfigure><caption>Two images displayed horizontally in one figure.</caption></figure>

The resulting figure is displayed below:

Blue on blue

An envelope with a blue page
Subfigure 1.

Orange on white

An envelope with a white page
Subfigure 2.
Two images displayed horizontally in one figure.

The optional orient attribute determines how the subfigures are arranged respective to one another. This attribute can have a value of either horizontal (default) or vertical . Modifying the previous example so that orient="vertical" results in the following:

Blue on blue

An envelope with a blue page
Subfigure 1.

Orange on white

An envelope with a white page
Subfigure 2.
Two images displayed vertically in one figure.

Only use subfigures when the images are related to one another.

Including alternate media for print

Connexions allows you to insert an alternate media file in your module that can be formatted and sizedspecifically for the print version of your content. For example, you may want to provide a color image for online use and a black-and-white image for print. You can also use this feature to provide alternatemedia types, such as using a Java applet for online use and an image for print.

To create an alternate image for print, simply include two image elements (or, say, a video element and an image element) inside the media tag. Use the for attribute to specify whether this element should be used for the online version, the PDF version, or used as the default selection.

The following code gives one example for including an alternate print image. In this case, online users will see image.png , while image.eps will be used for the print version of the module. <figure id='printimage'><media id="print_image_example"><image mime-type='image/png' src='image.png'/><image mime-type='application/postscript' src='image.eps' for="pdf"/></media></figure>

Possible values for the for attribute include:

  • (Default) This element is used for both PDF and online versions unless another, version-specific element is present.
  • This element is used only for the online version of the content.
  • This element is used only for the pdf version of the content.
Note that it is not necessary to specify a media element for both online and print versions. For example, given the code snippet above, the first image (" image.png ") is the default and will be automatically used for the online version of the content, while the second image (" image.eps ") is explicitly assigned to the PDF version of the content. If no default had been specified, then no image would have appeared in the online version of the content.

fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.

what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
