The first phthalocyanine compound in the class of macrocyclic compounds was obtained as a dark blue colored byproduct during the synthesis of o-cyanobenzamide from acetic acid and phthalimide in 1907 [1]. 20 years later, the first copper me…

Organic dyes and complexes such as phthalocyanines (Pcs) may show photocatalytic properties against to photocatalytic degradation of pollutants [1]. The use of metallo phthalocyanines as organic photocatalysts in solution derives from their…

Energy conversion systems are very diverse. One of the most important of these systems is undoubtedly the electric machines. Mechanical energy production from electricity has been ongoing for about 150 years. With rapid developing technolog…

Variable magnetic fields are widely used in energy production. Two methods can be applied to make the magnetic field variable. The first of these is to apply an alternating current to the insulated conductor on the outer surface of a core. …

Scientific and technical field of multiple disciplines working on lighting, is of great importance in our daily lives. Especially when energy saving is aimed at illumination of houses, other elements are mostly ignored. This situation, whic…
