Production of ceramics (Ni0.5,Zn0.5)Fe2O4 by hot pressing of SHS powders

open access: yesDiscover Materials
A method for the synthesis of ferrites with the structure of the spinel mineral was developed by the method of self-propagating high-temperature synthesis (SHS). Different fuel-oxidizer ratios were used for the synthesis.

A Geometria de Lobachevsky

open access: yes, 2013
The geometry is considered as a logical and deductible science. Euclid was the first mathematician to formulate and organize the knowledge within the geometry, in a work called 'The Elements'. Euclid developed his work based on five postulates. The fifth caused controversy because it had not the same intuitive evidence of the remaining ones.
