Abstract Zinc oxide is one of the most researched semiconductors owing to outstanding properties that make it useful in various industrial applications, such as solar cells and other optoelectronics. In this work, ZnO thin films were prepared five different concentrations doped with four nitrogen atoms from triethylene tetramine (TETA) fabricate a for optoelectronic applications using an electr...

A large set of lowest and medium energy conformers of aliphatic tetramine trien was used to uncover structural-topological preferences of poliamines. Numerous common structural features among HL and H 2 L tautomers were identified, e.g., H-atoms of protonated functional groups are always involved in intramolecular NH•••N interactions and they result in as large and as many as possible rings in ...

WILSON'S disease is a rare genetic condition associated with excess copper deposition in the tissues, principally liver and brain. It first became established as a clinical entity in 1912, following Kinnear Wilson's publication of thirteen cases.' The incidence has been estimated to be about one case per million of the population2 although Walshe3 considers it is likely to be more common than t...
