Nanostructured films of copper, zinc, and nickel oxides were obtained from a controlled oxidation the ternary silver (Cu-Zn-Ni) substrates through one-pot, green, low temperature vapor-based treatment. Brief contact alloy with ammonia hydrogen peroxide vapors at room originates mixture nanometric its surface. The growths evolve time temperature, generating layered film highly dispersed copper n...

First-principles all electrons density-functional calculations for the band structure and magnetization of Zn1−xCoxO ternary magnetic alloys, in three phases namely zinc-blende, rocksalt wurtzite have been reported. The computations are spin-polarized. An inspection our electronic properties showed that alloy system interest exhibits a semiconducting character where nature gap depends on consid...

The present work has as main aim to make a small introduction about the types of steels, specially the ones used in the construction industry. This material is appreciated in construction due to its many advantages as strengths, resistance, adaptability and flexibility in design, durability, recyclability,...; even thou its also has week points like a low resistance to fire, weak against corros...
