Una poema vieja y un articulo de quimica.

En el juicio de los muertos frente a osiris
mi corazon romperia la balanza
Y sin embargo no consigo darme cuenta
que fantasma dara a luz mi desconfianza
Pero prometo, a mas nadie que a mi mismo
triunfar de nuevo en este juego apasionado
Y el dia que ya no le tema a los abismos
Agradecer a quien estuvo siempre al lado..

No quiero cantar victoria
por describir lo que siento
En mi estado, tras la gloria
y el imperdible momento
Y a vos cancion, de ira y esperanzaprometo no abandonarte
Yo tambien tengo un nudo en la panza
por no poder liberarte
pero, pero al menos por ahora
tu lugar es un cajon
porque es falta de respeto, cantarte sin emocion
Y este intruso que hay en mi, no te merece cantarte
merece alguien mas grande
capaz de inmortalizarte...

I figured it would be different to do something like this today, like it?
Completely changing the topic, however...listen to this.

A group of researchers have now developed a novel reaction scheme by which CO₂ can be efficiently converted into methanol under very mild conditions. As reported in the journal Angewandte Chemie (German for "Applied Chemistry"), it is based on an N-heterocyclic carbene catalyst and a silane as the reducing agent. The basic framework of an N-heterocyclic carbene is a five-membered ring made of two nitrogen and three carbon atoms. Instead of having the usual four bonds, one of these carbon atoms only has two. The two electrons left over in the form of a lone pair, which makes this species highly reactive—reactive enough to attack CO₂.

WHY DO WE GIVE???
The big advantage: unlike prior reaction mechanisms using metal-containing catalysts, air can be used as the source of the CO₂ because the carbene catalyst is not sensitive to oxygen. The carbene is more efficient than the metal-containing catalysts as well, and the reaction can be carried out under very mild conditions. In contrast to the usual sources of carbon used today—fossil fuels and natural gas—carbon dioxide is a renewable resource and an environmentally friendly chemical reagent.

The carbene activates the CO₂, but is then split off again to end the reaction cycle in its original state. The formal reaction partner is a
hydrosilane(from wiki)--Any of a class of compounds in which one or more hydrogen atoms of a silane are replaced by alkyl groups.

The reaction product into which the CO₂ is converted can easily be collected in the form of methanol in the last step of the reaction series. Methanol is an important starting material for many chemical syntheses and serves as an alternative fuel and as a raw material for the production of energy in methanol fuel cells.

Other reasons for importantce?? Previous attempts to reduce carbon dioxide to more useful products have required more energy input and a much longer reaction time. They also require transition metal catalysts, which are both unstable in oxygen and expensive.

Woot! Una otra manera eficaz para sustinir el medio ambiente y tambien, los dolares que estan en nos pantalones!!
