Main on going  Research Projects in Chemical Education : Crystal Growth by Heterogeneous Nucleation. Chemical Microscopy.

Galleries

The main goal of these galleries and Internet pages it is not, at least at this stage, to include  educational or scientific contents and procedures.

It is our goal to show beautiful images connected to Chemistry and other related Sciences, mainly Crystal Growth and Microscopy.

The scientific or educational procedures related to the images displayed are included in the bibliography cited above, together with each picture, or to be published.

The major goal of the galleries it is to promote Chemistry in Portuguese Schools or other Institutions in cooperation with Instituto Superior Técnico.

Cooperation abroad is also welcome. Join us in "Rede cristalina", a crystals network, by just sending an email.

These images are covering 14  years of research on Education in Chemistry, at Centro de Química Estrutural, Instituto Superior Técnico, within the scope of Projects like Ciência Viva and others from the Department of Chemical Engineering and Biology.

Pictures are supposed to be beautiful but, as many of them were obained in schools, and sometimes by students, they may be  not of high quality but still, they represent their efforts and enthousiasm for Chemistry. I think they deserve our respect.

Copyright protected. However, the use of the images is allowed, as long as the citation is correctly given and for non-commercial usages only. The download is free, and the use of the Internet Explorer is recommended. Links are encouraged.
