• group of E.J.Corey (Chemical Nobel prize - 1990) has published a new synthesis of the Oseltamivir (Tamiflu) without needing using the expensive method that implies the use of sikimico acid, fundamental part in the obtaining of the Tamiflu. Given to the international spirits on the bird influenza and the pandemic that has been triggered from the 2003, the scientists have decided not to patent their procedure and to lighten the costs.

• Chemists in the group of A.Prasanna de Silva in the Queen's University of Belfast have designed a compound that contains three electrolyte receptors in a small molecule. The substance is a molecular or molecular logical door logic gate and has been published in the JACS, the molecule is capáz to detect zinc and sodium ions in an aqueous solution.

• great ethylene explosion in the department of chemist of a university in Mulhouse, France, caused the death of a professor, Dominique Burget, and hurt seriously to another one. The incident happened in the Ecole Nationale Supérieure de Chimie de Mulhouse leaves from the University of Haute-Alsace.

• German transnational company Schering Ag was sold to Bayer Pharmaceuticals by 16.3 millardos (16,300 million) of Euros after a robust one bids up between this last and company Merck KGaA that offered 14.9 millardos (14,900 million) of Euros. The executive director of Bayer, Werner Wenning declared that after finalized this acquisition 6.000 places of work possibly will be eliminated in the coming years.

The Thermochemistry is a subdiscipline of the fisicoquímica that studies the chemical heat exchanges in processes of change, as they are it the chemical reactions. It is possible to be considered that the chemical reactions are isobaric, that is to say, they take place to constant pressure (open atmosphere, that is to say, P=1 atm), or can be considered that they take place to constant volume (the one of the receiver where they are being realized).

Being heat interchanges to constant pressure, the magnitude characteristic of the thermochemistry is the increase of enthalpy, that is to say, the heat variation that will occur in the passage of reagents to products.
