A series of unsymmetrical tetrapyrazinoporphyrazines (TPyzPzs) from the group of azaphthalocyanines with one peripherally attached amino substituent (donor) were synthesized, and their photophysical p

The poor electronic properties of the GaAs surface and GaAs-insulator interfaces, generally resulting from large density of surface/interface states, have limited GaAs device technology.

Nanoscale CexFe1-xO2 solid solutions with high surface area were prepared by a modified template route using an ultrahigh surface area carbon material as the template and nitrate as the oxide precurso
