Síntesis y almacenamiento de carga de la nueva aleación polipirrol/poli(ácido maleico-olefina)
The influence that the electrosynthesis conditions of the polypyrrole/poly(maleic acid-co-olefin) blend have on the charge storage ability (amount of electrical charge stored (mC) per unit mass (mg) of electrogenerated polymer) has been analysed. This is

La transición de fase I4/mcm→Pm3m en Sr0.5Ba0.5HfO3-δ
The effect of partial substitution of cations in AMO3 compounds have been studied because the physical properties and applications of these materials can be improved. In particular we are interested in the Sr1-xBaxHfO3 family.
