# 0.6 Presentation token elements (others)

 Page 1 / 2

## "mtext" token element

The “mtext” element plays similar role of rendering characters like “mo” amd “mn” elements, but with a difference. It does not convey the notional or symbolic aspect of mathematical identities and numbers, which require specific presentation and manipulation to convey mathematical meaning. The “mtext” element is used to present plain text, which may be used for comments and clarification.

This element is also useful to deliver white space and mixing verbose mathematical rendering consisting of word string. For example, we would need to say “The presentation of alpha character in MathML looks like : α”.

## Display with "mtext" element

<m:math display="block"> <m:mtext>The presentation of alpha character in MathML is : </m:mtext> <m:mi>&alpha;</m:mi> </m:math>

Save the file after editing as “test4.xml”. The display looks like :

$\text{The presentation of alpha character in MathML is :}\alpha$

Though “mtext” element manages the empty space within the string of words, but not around it. In order to enhance, readability, style and presentation, we may add empty space, using "&ThinSpace" entity character.

## Display with "mtext" element

<m:math display="block"> <m:mtext>The presentation of alpha character in MathML is : &ThinSpace; </m:mtext> <m:mi>&alpha;</m:mi> </m:math>

Save the file after editing as “test4.xml”. The display looks like :

$\text{The presentation of alpha character in MathML is : \hspace{0.17em}}\alpha$

Color and size management of the content of “mtext” element is implemented with the common attributes of the token element i.e. mathvariant, mathsize, mathcolor and mathbackground directly on "mtext" element.

## Display with "mtext" element

<m:math display="block"> <m:mtext mathvariant='bold' mathcolor='#fff' mathsize='12pt' mathbackground='#f55'> Example : </m:mtext> <m:mtext mathsize='10pt'> The above example illustrates application of “mfrac” element. </m:mtext> </m:math>

Save the file after editing as “test.xml”. The display looks like :

$\colorbox[rgb]{1,0.333333333333333,0.333333333333333}{{\mathbf{\text{Example :}}}}\text{This example illustrates application of theorem.}$

In general, mixing of text with mathematics may be implemented, using any of the three possibilities discussed here. First, we can rely on the rendering facility of the document in which “MathML” is embedded. This document could be any valid “xml” document, including HTML. Second, we may use the text rendering by “mtext” element as explained above. This is appropriate for text, which is neither the part of the general text flow in the document nor the part of the notional display of mathematical expression. It suits the requirement of text rendering, used for qualifying mathematical expression or comments. Third, displaying text with “mi” element, which is inline with the mathematical expression or a part of it.

## Attribute value types

• width (default : "0em"): number h-unit | namedspace
• height (default : "0ex"): number v-unit
• depth (default : "0ex"): number v-unit
• linebreak (default : "auto"): auto | newline | indentingnewline | nobreak | goodbreak | badbreak

Is there any normative that regulates the use of silver nanoparticles?
what king of growth are you checking .?
Renato
What fields keep nano created devices from performing or assimulating ? Magnetic fields ? Are do they assimilate ?
why we need to study biomolecules, molecular biology in nanotechnology?
?
Kyle
yes I'm doing my masters in nanotechnology, we are being studying all these domains as well..
why?
what school?
Kyle
biomolecules are e building blocks of every organics and inorganic materials.
Joe
anyone know any internet site where one can find nanotechnology papers?
research.net
kanaga
sciencedirect big data base
Ernesto
Introduction about quantum dots in nanotechnology
what does nano mean?
nano basically means 10^(-9). nanometer is a unit to measure length.
Bharti
do you think it's worthwhile in the long term to study the effects and possibilities of nanotechnology on viral treatment?
absolutely yes
Daniel
how to know photocatalytic properties of tio2 nanoparticles...what to do now
it is a goid question and i want to know the answer as well

for teaching engĺish at school how nano technology help us
Anassong
Do somebody tell me a best nano engineering book for beginners?
there is no specific books for beginners but there is book called principle of nanotechnology
NANO
what is fullerene does it is used to make bukky balls
are you nano engineer ?
s.
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.
Tarell
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.
Tarell
what is the Synthesis, properties,and applications of carbon nano chemistry
Mostly, they use nano carbon for electronics and for materials to be strengthened.
Virgil
is Bucky paper clear?
CYNTHIA
carbon nanotubes has various application in fuel cells membrane, current research on cancer drug,and in electronics MEMS and NEMS etc
NANO
so some one know about replacing silicon atom with phosphorous in semiconductors device?
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.
Harper
Do you know which machine is used to that process?
s.
how to fabricate graphene ink ?
for screen printed electrodes ?
SUYASH
What is lattice structure?
of graphene you mean?
Ebrahim
or in general
Ebrahim
in general
s.
Graphene has a hexagonal structure
