New tools and materials make the architectural art teaching straighter, more general, more aesthetic and quicker. (4) New concepts and tools update day after day, which requires the teaching process constantly change.
Every student has their own creation, with their unique materials, techniques and forms.
At the same time, architecture, art, composition and materials are combined.

On the other hand, release of P from production and life of human being is one of the primary nutrients which leads to eutrophication and threatens the dwindling water resources .In order to reduce the negative effects of overloading the ecosystems with P, it is necessary to investigate various techniques and materials that could contribute to the removal as well as recycling of P.
In Fig.1b, the well dispersed white materials were magnesium oxide ,as an active component MgO played an important role in the process of adsorption.
