&lt;br /&gt;
This takes you to an &#039;&#039;&#039;Export&#039;&#039;&#039; page. A backup of the Projects area can be made (in XML) if you want to keep your own &#039;&#039;snapshot&#039;&#039; of the project pages at any instant. After you Export the page you want (ie &#039;&#039;&#039;It:projects&#039;&#039;&#039; or &#039;&#039;&#039;It:Lignocaine&#039;&#039;&#039; for example) the XML encoding of it will appear in your browser Window. You should &#039;&#039;&#039;view source&#039;&#039;&#039; for this material, copy it to a text editor, and thence save it to disk.&lt;br /&gt;
&lt;br /&gt;
== Overlaps ==&lt;br /&gt;
&lt;br /&gt;
If someone else  starts editing a page at the same time as you,   the system will detect this and offer alternatives for you to deal with.  For example, it may suggest you copy the contents of the page you have been editing and merge it into the other person&#039;s page,&lt;br /&gt;
so that both the sets of edits are preserved.  Read the on-screen instructions carefully!&lt;br /&gt;
&lt;br /&gt;
Another precaution you could take is to keep a copy of the contents of the page you are editing in eg Wordpad (or Word),&lt;br /&gt;
make the changes there, and then copy the entire lot to the  Wiki page to preview and then save. That way, if your contribution&lt;br /&gt;
is overlapped by someone else, you will still have a copy, and you can then resubmit it.&lt;br /&gt;

&lt;div&gt;Ferrocene is an organomettalic compound of a type known as sandwich compounds. The name is because the central metal atom is bound between two cyclopentadienyl rings like the filling of a sandwich. The chemical formula of this compound is Fe(C&amp;lt;sub&amp;gt;5&amp;lt;/sub&amp;gt;H&amp;lt;sub&amp;gt;5&amp;lt;/sub&amp;gt;)&amp;lt;sub&amp;gt;2&amp;lt;/sub&amp;gt;.&lt;br /&gt;

&lt;br /&gt;
Ferrocene is famous for its &#039;sandwich structure&#039;. This is where the two cyclopentadiene molecules are situated above and below the iron centre, with the bonding occuring via the pi-electrons of the aromatic rings, which are shared with the central iron ion. This delocalised configuration of electrons is particularly stable. X-Ray diffraction in 1952 by Fisher showed that the cylopentadiene rings are staggered.&lt;br /&gt;
&lt;br /&gt;
== History ==&lt;br /&gt;
&lt;br /&gt;
Ernst Fischer and Geoffrey Wilkinson (Inorganic Chemist at Imperial College, London) were awarded the Nobel prize for Chemistry in 1974 for his work in determining the structure of ferrocene. This was for work done 20 years earlier starting in 1952(ref 2), after the compound had first been synthesised in December 1951 by T.J. Kealy and P.L. Pauson (ref 3).&lt;br /&gt;

&lt;br /&gt;
== Chemical Reactions ==&lt;br /&gt;
&lt;br /&gt;
Ferrocene&#039;s characteristic chemical property is that it can do one-electron oxidation reactions at low potentials. Oxidation reactions often use Ferrocenium salts as the oxidant because the redox product of these reactions is ferrocene itself. This is inert enough that it can be readily removed from the desired products.&lt;br /&gt;
&lt;br /&gt;
Apart from this, Ferrocene is also capable of undergoing Friedel-Crafts reactions in the same manner as a regular aromatic compound.&lt;br /&gt;
&lt;br /&gt;
It can also be deprotonated by a strong base such as an organolithium compound. This will result in 1,1&#039;-dilithioferrocene (Chemical Formula:Fe(C&amp;lt;sub&amp;gt;5&amp;lt;/sub&amp;gt;H&amp;lt;sub&amp;gt;4&amp;lt;/sub&amp;gt;Li&amp;lt;sub&amp;gt;2&amp;lt;/sub&amp;gt;)which is a powerful nucleophile.&lt;br /&gt;
&lt;br /&gt;
== Physical Properties ==&lt;br /&gt;
&lt;br /&gt;
Ferrocene is an yellow-orange solid that stable in air. Ferrocene is soluble in organic solvents but is insoluble in water. Ferrocene will sublime in a vacuum&lt;br /&gt;
&lt;br /&gt;
==Uses of Ferrocene==&lt;br /&gt;
&lt;br /&gt;
Because ferrocene will sublime easily in a vaccuum, it is often used to deposit fullerenes. Apart from this, most of the uses involve ferrocene derivatives rather than ferrocene itself.&lt;br /&gt;
&lt;br /&gt;
Ferrocene can be used in diesel to prevent soot production and in petrol as an anti-knocking agent (it increases the fuels octane rating, meaning that it makes them less likely to detonate early, causing damage to an engine). It is considered safer to use than, for example, Tetra-ethyl lead, but can lead to other problems over time (i.e. sparkplug failure).&lt;br /&gt;
&lt;br /&gt;
Certain salts of ferrocene are being used in experimental anti-cancer drugs including Tamoxifen which is used as a treatment for breast cancer.&lt;br /&gt;
&lt;br /&gt;
It is possible to use ferrocenyl phosphines as ligand scaffolds in reactions catalysed by transition-metals.&lt;br /&gt;

Ferrocene is famous for its &#039;sandwich structure&#039;. This is where the two cyclopentadiene molecules are situated above and below the iron centre, with the bonding occuring via the pi-electrons of the aromatic rings, which are shared with the central iron ion. This delocalised configuration of electrons is particularly stable. X-Ray diffraction in 1952 by Fisher showed that the cylopentadiene rings are staggered.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
Ernst Fischer and Geoffrey Wilkinson (Inorganic Chemist at Imperial College, London) were awarded the Nobel prize for Chemistry in 1974 for his work in determining the structure of ferrocene. This was for work done 20 years earlier starting in 1952(ref 2), after the compound had first been synthesised in December 1951 by T.J. Kealy and P.L. Pauson (ref 3).&lt;br /&gt;

Ferrocene is an yellow-orange solid that stable in air. Ferrocene is soluble in organic solvents but is insoluble in water. Ferrocene will sublime in a vacuum&lt;br /&gt;
&lt;br /&gt;
==Uses of Ferrocene==&lt;br /&gt;
&lt;br /&gt;
Because ferrocene will sublime easily in a vaccuum, it is often used to deposit fullerenes. Apart from this, most of the uses involve ferrocene derivatives rather than ferrocene itself.&lt;br /&gt;
&lt;br /&gt;
Ferrocene can be used in diesel to prevent soot production and in petrol as an anti-knocking agent (it increases the fuels octane rating, meaning that it makes them less likely to detonate early, causing damage to an engine). It is considered safer to use than, for example, Tetra-ethyl lead, but can lead to other problems over time (i.e. sparkplug failure).&lt;br /&gt;
&lt;br /&gt;
Certain salts of ferrocene are being used in experimental anti-cancer drugs including Tamoxifen which is used as a treatment for breast cancer.&lt;br /&gt;
&lt;br /&gt;
It is possible to use ferrocenyl phosphines as ligand scaffolds in reactions catalysed by transition-metals.&lt;br /&gt;

&lt;div&gt;Ferrocene is an organomettalic compound of a type known as sandwich compounds. The name is because the central metal atom is bound between two cyclopentadienyl rings like the filling of a sandwich.

&lt;br /&gt;
&lt;br /&gt;
Ferrocene is famous for its &#039;sandwich structure&#039;. This is where the two cyclopentadiene molecules are situated above and below the iron centre, with the bonding occuring via the pi-electrons of the aromatic rings, which are shared with the central iron ion. This delocalised configuration of electrons is particularly stable. X-Ray diffraction in 1952 by Fisher showed that the cylopentadiene rings are staggered.&lt;br /&gt;
&lt;br /&gt;
== History ==&lt;br /&gt;
&lt;br /&gt;
Ernst Fischer and Geoffrey Wilkinson (Inorganic Chemist at Imperial College, London) were awarded the Nobel prize for Chemistry in 1974 for his work in determining the structure of ferrocene. This was for work done 20 years earlier starting in 1952(ref 2), after the compound had first been synthesised in December 1951 by T.J. Kealy and P.L. Pauson (ref 3).&lt;br /&gt;

== Physical Properties ==&lt;br /&gt;
&lt;br /&gt;
Ferrocene is an yellow-orange solid that stable in air. Ferrocene is soluble in organic solvents but is insoluble in water. Ferrocene will sublime in a vacuum&lt;br /&gt;
&lt;br /&gt;
==Uses of Ferrocene==&lt;br /&gt;
&lt;br /&gt;
Because ferrocene will sublime easily in a vaccuum, it is often used to deposit fullerenes. Apart from this, most of the uses involve ferrocene derivatives rather than ferrocene itself.&lt;br /&gt;
&lt;br /&gt;
Ferrocene can be used in diesel to prevent soot production and in petrol as an anti-knocking agent (it increases the fuels octane rating, meaning that it makes them less likely to detonate early, causing damage to an engine). It is considered safer to use than, for example, Tetra-ethyl lead, but can lead to other problems over time (i.e. sparkplug failure).&lt;br /&gt;
&lt;br /&gt;
Certain salts of ferrocene are being used in experimental anti-cancer drugs including Tamoxifen which is used as a treatment for breast cancer.&lt;br /&gt;

&lt;div&gt;Ferrocene is an organomettalic compound of a type known as sandwich compounds. The name is because the central metal atom is bound between two cyclopentadienyl rings like the filling of a sandwich. The chemical formula of this compound is Fe(C&amp;lt;sub&amp;gt;5&amp;lt;/sub&amp;gt;H&amp;lt;sub&amp;gt;5&amp;lt;/sub&amp;gt;)&amp;lt;sub&amp;gt;2&amp;lt;/sub&amp;gt;.&lt;br /&gt;

&lt;div&gt;Ferrocene is an organomettalic compound of a type known as sandwich compounds. The name is because the central metal atom is bound between two cyclopentadienyl rings like the filling of a sandwich. The chemical formula of this compound is Fe(C&amp;lt;sub&amp;gt;5&amp;lt;/sub&amp;gt;H&amp;lt;sub&amp;gt;5&amp;lt;/sub&amp;gt;)&amp;lt;sub&amp;gt;2&amp;lt;/sub&amp;gt;.&lt;br /&gt;

&#039;&#039;&#039;Retinal&#039;&#039;&#039;, also known as retinaldehyde or retinene&amp;lt;sub&amp;gt;1&amp;lt;/sub&amp;gt; is the most important molecule associated with vision. Retinal changes structure when it is exposed to light, essentially transferring the energy from the light it absorbs to an electrical impulse in the retina of the eye, which is then passed along the optic nerve to the central nervous system to be processed. All vision systems operate in this manner, so Retinal is resposible for all vision. Retinal is a retinine molecule that exists as two different isomers - 11-cis retinal and all-trans retinal.&lt;br /&gt;

==The role of retinal in the vision process==&lt;br /&gt;
&lt;br /&gt;
The molecule that takes part in the vision process is rhodopsin which consists of 11-cis retinal and protein opsin. Retinal is a Vitamin A derivative. When there is no light present the 11-cis retinal has a bent configuration and is attached to the retinal molecule in a stable arrangement. When light strikes the retina, the retinal molecule absorbs a photon into one of the pi-bonds between the 11th and 12th carbon atoms, hence the 11 cis retinal is transfformed into the all trans retinal.&lt;br /&gt;

==Effects of Bunazosin on ocular circulation and retinal neuronal damage==&lt;br /&gt;
&lt;br /&gt;
By applying bunazosin hydrochloride into a healthy humans, it increases the blood velocity in the optic nerve head(ONH),retina and choroid, without changing either heart rate and blood pressure dramaticallt. This drug was also applied to rabbits and rats, giving positive results. These shows that bunazosin hydrochloride have improvement effect both in the ocular circulation and a direct neuroprotective effct. Therefore, it may be useful to use bunazosin hydrochloride as a therapeutic drug against retinal diseases which is associated with the ocular circulation.&lt;br /&gt;

Ferrocene is famous for its &#039;sandwich structure&#039;. This is where the two cyclopentadiene molecules are situated above and below the iron centre, with the bonding occuring via the pi-electrons of the aromatic rings, which are shared with the central iron ion. This delocalised configuration of electrons is particularly stable. X-Ray diffraction in 1952 by Fisher showed that the cylopentadiene rings are staggered.&lt;br /&gt;
&lt;br /&gt;
== History ==&lt;br /&gt;
&lt;br /&gt;
Ernst Fischer and Geoffrey Wilkinson (Inorganic Chemist at Imperial College, London) were awarded the Nobel prize for Chemistry in 1974 for his work in determining the structure of ferrocene. This was for work done 20 years earlier starting in 1952(ref 2), after the compound had first been synthesised in December 1951 by T.J. Kealy and P.L. Pauson (ref 3).&lt;br /&gt;

Ferrocene is famous for its &#039;sandwich structure&#039;. This is where the two cyclopentadiene molecules are situated above and below the iron centre, with the bonding occuring via the pi-electrons of the aromatic rings, which are shared with the central iron ion. This delocalised configuration of electrons is particularly stable. X-Ray diffraction in 1952 by Fisher showed that the cylopentadiene rings are staggered.&lt;br /&gt;

Ferrocene is famous for its &#039;sandwich structure&#039;. This is where the two cyclopentadiene molecules are situated above and below the iron centre, with the bonding occuring via the pi-electrons of the aromatic rings, which are shared with the central iron ion. This delocalised configuration of electrons is particularly stable. X-Ray diffraction in 1952 by Fisher showed that the cylopentadiene rings are staggered.&lt;br /&gt;
&lt;br /&gt;
== History ==&lt;br /&gt;
&lt;br /&gt;
Ernst Fischer and Geoffrey Wilkinson (Inorganic Chemist at Imperial College, London) were awarded the Nobel prize for Chemistry in 1974 for his work in determining the structure of ferrocene. This was for work done 20 years earlier starting in 1952(ref 2), after the compound had first been synthesised in December 1951 by T.J. Kealy and P.L. Pauson.&lt;br /&gt;

Ferrocene is famous for its &#039;sandwich structure&#039;. This is where the two cyclopentadiene molecules are situated above and below the iron centre, with the bonding occuring via the pi-electrons of the aromatic rings, which are shared with the central iron ion. This delocalised configuration of electrons is particularly stable. X-Ray diffraction in 1952 by Fisher showed that the cylopentadiene rings are staggered.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
Ernst Fischer and Geoffrey Wilkinson (Inorganic Chemist at Imperial College, London) were awarded the Nobel prize for Chemistry in 1974 for his work in determining the structure of ferrocene. This was for work done 20 years earlier starting in 1952, after the compound had first been synthesised in December 1951 by T.J. Kealy and P.L. Pauson.&lt;br /&gt;

Ferrocene is famous for its &#039;sandwich structure&#039;. This is where the two cyclopentadiene molecules are situated above and below the iron centre, with the bonding occuring via the pi-electrons of the aromatic rings, which are shared with the central iron ion. This delocalised configuration of electrons is particularly stable. X-Ray diffraction in 1952 by Fisher showed that the cylopentadiene rings are staggered.&lt;br /&gt;
&lt;br /&gt;
== History ==&lt;br /&gt;
&lt;br /&gt;
Ernst Fischer and Geoffrey Wilkinson (Inorganic Chemist at Imperial College, London) were awarded the Nobel prize for Chemistry in 1974 for his work in determining the structure of ferrocene. This was for work done 20 years earlier starting in 1952, after the compound had first been synthesised in December 1951 by T.J. Kealy and P.L. Pauson.&lt;/div&gt;</summary>

One precaution you could take is to keep a copy of the contents of the page you are editing in eg Wordpad (or Word),&lt;br /&gt;
make the changes there, and then copy the entire lot to the  Wiki page to preview and then save. Tht way, if your contribution&lt;br /&gt;
is overlapped by someone else, you will still have a copy, and you can then resubmit it.&lt;br /&gt;

&lt;div&gt;&#039;&#039;&#039;Retinal&#039;&#039;&#039; (aka: retinaldehyde or retinene&amp;lt;sub&amp;gt;1&amp;lt;/sub&amp;gt;) is the most important molecule associated with vision. Retinal changes structure when it is exposed to light, essentially transferring the energy from the light it absorbs to an electrical impulse in the retina of the eye, which is then passed along the optic nerve to the central nervous system to be processed. All vision systems operate in this manner, so Retinal is resposible for all vision. Retinal is a retinine molecule that exists as two different isomers - 11-cis retinal and all-trans retinal.&lt;br /&gt;

==Properties of all-trans retinal==&lt;br /&gt;
&lt;br /&gt;
==How is Retinal affected by the absorption of light?==&lt;br /&gt;
&lt;br /&gt;
The absorption of light causes the pi-bond to break allowing the molecule to rotate. This allows the retinal molecule to change shape. The new shape of the molecule affects the shape of the protein to which the retinal molecule is attached to. This process occurs via a signal that passes along the optic nerve.&lt;br /&gt;
&lt;br /&gt;

&lt;div&gt;&#039;&#039;&#039;Retinal&#039;&#039;&#039; (aka: retinaldehyde or retinene&amp;lt;sub&amp;gt;1&amp;lt;/sub&amp;gt;) is the most important molecule associated with vision. Retinal changes structure when it is exposed to light, essentially transferring the energy from the light it absorbs to an electrical impulse in the retina of the eye, which is then passed along the optic nerve to the central nervous system to be processed. All vision systems operate in this manner, so Retinal is resposible for all vision. Retinal is a retinine molecule that exists as two different isomers - 11-cis retinal and all-trans retinal.&lt;br /&gt;

&lt;br /&gt;
The absorption of light causes the pi-bond to break allowing the molecule to rotate. This allows the retinal molecule to change shape. The new shape of the molecule affects the shape of the protein to which the retinal molecule is attached to. This process occurs via a signal that passes along the optic nerve.&lt;br /&gt;

&lt;div&gt;&#039;&#039;&#039;Retinal&#039;&#039;&#039; (aka: retinaldehyde or retinene&amp;lt;sub&amp;gt;1&amp;lt;/sub&amp;gt;) is the most important molecule associated with vision. Retinal changes structure when it is exposed to light, essentially transferring the energy from the light it absorbs to an electrical impulse in the retina of the eye, which is then passed along the optic nerve to the central nervous system to be processed. All vision systems operate in this manner, so Retinal is resposible for all vision. Retinal is a retinine molecule that exists as two different isomers - 11-cis retinal and all-trans retinal.&lt;br /&gt;

&lt;br /&gt;
==How is Retinal affected by the absorption of light?==&lt;br /&gt;
&lt;br /&gt;
The absorption of light causes the pi-bond to break allowing the molecule to rotate. This allows the retinal molecule to change shape. The new shape of the molecule affects the shape of the protein to which the retinal molecule is attached to. This process occurs via a signal that passes along the optic nerve.&lt;br /&gt;

&lt;div&gt;&#039;&#039;&#039;Retinal&#039;&#039;&#039; (aka: retinaldehyde or retinene&amp;lt;sub&amp;gt;1&amp;lt;/sub&amp;gt;) is the most important molecule associated with vision. Retinal changes structure when it is exposed to light, essentially transferring the energy from the light it absorbs to an electrical impulse in the retina of the eye, which is then passed along the optic nerve to the central nervous system to be processed. All vision systems operate in this manner, so Retinal is resposible for all vision. Retinal is a retinine molecule that exists as two different isomers - 11-cis retinal and all-trans retinal.&lt;br /&gt;

&lt;br /&gt;
==How is Retinal affected by the absorption of light?==&lt;br /&gt;
&lt;br /&gt;
The absorption of light causes the pi-bond to break allowing the molecule to rotate. This allows the retinal molecule to change shape. The new shape of the molecule affects the shape of the protein to which the retinal molecule is attached to. This process occurs via a signal that passes along the optic nerve.&lt;br /&gt;

&lt;div&gt;&#039;&#039;&#039;Retinal&#039;&#039;&#039; (aka: retinaldehyde or retinene&amp;lt;sub&amp;gt;1&amp;lt;/sub&amp;gt;) is the most important molecule associated with vision. Retinal changes structure when it is exposed to light, essentially transferring the energy from the light it absorbs to an electrical impulse in the retina of the eye, which is then passed along the optic nerve to the central nervous system to be processed. All vision systems operate in this manner, so Retinal is resposible for all vision. Retinal is a retinine molecule that exists as two different isomers - 11-cis retinal and all-trans retinal.&lt;br /&gt;

&lt;br /&gt;
==How is Retinal affected by the absorption of light?==&lt;br /&gt;
&lt;br /&gt;
The absorption of light causes the pi-bond to break allowing the molecule to rotate. This allows the retinal molecule to change shape. The new shape of the molecule affects the shape of the protein to which the retinal molecule is attached to. This process occurs via a signal that passes along the optic nerve.&lt;br /&gt;

&lt;div&gt;&#039;&#039;&#039;Retinal&#039;&#039;&#039; (aka: retinaldehyde or retinene&amp;lt;sub&amp;gt;1&amp;lt;/sub&amp;gt;) is the most important molecule associated with vision. Retinal changes structure when it is exposed to light, essentially transferring the energy from the light it absorbs to an electrical impulse in the retina of the eye, which is then passed along the optic nerve to the central nervous system to be processed. All vision systems operate in this manner, so Retinal is resposible for all vision. Retinal is a retinine molecule that exists as two different isomers - 11-cis retinal and all-trans retinal&lt;br /&gt;

==How is Retinal affected by the absorption of light?==&lt;br /&gt;
&lt;br /&gt;
The absorption of light causes the pi-bond to break allowing the molecule to rotate. This allows the retinal molecule to change shape. The new shape of the molecule affects the shape of the protein to which the retinal molecule is attached to. This process occurs via a signal that passes along the optic nerve.&lt;br /&gt;

This takes you to an  &#039;&#039;&#039;Export&#039;&#039;&#039; page.  A backup of the  Projects area can be made (in XML)  if you want to keep your own&lt;br /&gt;
&#039;&#039;snapshot&#039;&#039; of the project pages at any instant. After you Export the page you want (ie &#039;&#039;&#039;It:projects&#039;&#039;&#039; or  &#039;&#039;&#039;It:Lignocaine&#039;&#039;&#039;  for example) the XML encoding of it will appear in your browser Window.  You should  &#039;&#039;&#039;view source&#039;&#039;&#039; for this material, copy it to a text editor, and thence save it to disk.&lt;br /&gt;
&lt;br /&gt;
== Overlaps ==&lt;br /&gt;
&lt;br /&gt;
If two people start editing a page at the same time, and  &#039;&#039;&#039;save&#039;&#039;&#039; the change simultaneously, its possible only one of the changes&lt;br /&gt;
will be made permanent.  If anyone spots this happening, please let  me know. &lt;br /&gt;
&lt;br /&gt;
One precaution you could take is to keep a copy of the contents of the page you are editing in eg Wordpad (or Word),&lt;br /&gt;
make the changes there, and then copy the entire lot to the  Wiki page to preview and then save. Tht way, if your contribution&lt;br /&gt;
is overlapped by someone else, you will still have a copy, and you can then resubmit it.&lt;br /&gt;

=== Wiki Templates ===&lt;br /&gt;
&lt;br /&gt;
[[Template:DOI]] and [[Template:Doi-inline]] are providea as (protected) templates for your use.  Many other templates exist, often to be found on e.g. Wikipedia pages.  You may decide one of these is of particular use, or of interest.  If so, you can install it on the wiki here for you and others to use.  Add below a line that looks like  {{template-name|parameter}}, save, and click on the red text to create the new template. If you prefer the task of adding useful templates to that of adding information about molecules, then you will be given full credit for performing this valuable service for others!&lt;br /&gt;

== Supplemental  Project Page ==&lt;br /&gt;
&lt;br /&gt;
This area is for people who wish to create their own projects if none of the above appeal to them. Click on the  &#039;&#039;&#039;Edit&#039;&#039;&#039;  button to the right to open up an editable page,&lt;br /&gt;
then add an entry below as follows&lt;br /&gt;
&lt;br /&gt;
*&amp;lt;nowiki&amp;gt; [[it:name_of_project|Descriptive name of intended project]]&amp;lt;/nowiki&amp;gt;&lt;br /&gt;
*This will produce the effect:  [[it:name_of_project|Descriptive name of intended project]]&lt;br /&gt;

== [[Special:Export|Export Pages]] ==&lt;br /&gt;
&lt;br /&gt;
This takes you to an  &#039;&#039;&#039;Export&#039;&#039;&#039; page.  A backup of the  Projects area can be made (in XML)  if you want to keep your own&lt;br /&gt;
&#039;&#039;snapshot&#039;&#039; of the project pages at any instant. After you Export the page you want (ie &#039;&#039;&#039;It:projects&#039;&#039;&#039; or  &#039;&#039;&#039;It:Lignocaine&#039;&#039;&#039;  for example) the XML encoding of it will appear in your browser Window.  You should  &#039;&#039;&#039;view source&#039;&#039;&#039; for this material, copy it to a text editor, and thence save it to disk.&lt;br /&gt;
&lt;br /&gt;
== Overlaps ==&lt;br /&gt;
&lt;br /&gt;
If two people start editing a page at the same time, and  &#039;&#039;&#039;save&#039;&#039;&#039; the change simultaneously, its possible only one of the changes&lt;br /&gt;
will be made permanent.  If anyone spots this happening, please let  me know. &lt;br /&gt;
&lt;br /&gt;
One precaution you could take is to keep a copy of the contents of the page you are editing in eg Wordpad (or Word),&lt;br /&gt;
make the changes there, and then copy the entire lot to the  Wiki page to preview and then save. Tht way, if your contribution&lt;br /&gt;
is overlapped by someone else, you will still have a copy, and you can then resubmit it.&lt;br /&gt;

=== Wiki Templates ===&lt;br /&gt;
&lt;br /&gt;
[[Template:DOI]] and [[Template:Doi-inline]] are providea as (protected) templates for your use.  Many other templates exist, often to be found on e.g. Wikipedia pages.  You may decide one of these is of particular use, or of interest.  If so, you can install it on the wiki here for you and others to use.  Add below a line that looks like  {{template-name|parameter}}, save, and click on the red text to create the new template. If you prefer the task of adding useful templates to that of adding information about molecules, then you will be given full credit for performing this valuable service for others!&lt;br /&gt;
