Improvement of nucleation and electrical properties of Bi3.15Nd0.85Ti2.99Mn0.01O12 thin films with an upper Bi4Ti3O12 buffer layer
A highly (117)-preferred Bi3.15Nd0.85Ti2.99Mn0.01O12 (BNTM) thin film with an upper Bi4Ti3O12 (BTO) buffer layer was fabricated on Pt(111)/Ti/SiO2/Si(100) substrates by a sol–gel method. The effects of the added ...

Large-scale synthesis of hierarchical alpha-FeOOH flowers by ultrasonic-assisted hydrothermal route
In this paper, we report a facile, an environmental friendly ultrasonic-assisted hydrothermal route for preparation of goethite flower structures using Fe nanopowders at low temperature (85°C). The flower stru...

Corrosion wear behavior of Al-bronzes in 3.5% NaCl solution
The corrosion wear behaviors of two aluminum bronzes, Cu-14Al-X and QAl9-4, in 3.5% NaCl solution were investigated on a pin-on-block reciprocating tester. It was found that the wear loss of the bronzes in 3.5...

Raman Scattering from [(CdSe)m(ZnSe)n]p-ZnSe Quantum Wells
Raman scattering from a (CdSe)m(ZnSe)n-ZnSe strained quantum well structure, composed of (CdSe)m(ZnSe)n as well layers and thick ZnSe as barrier layers, is presented in this report. Two kinds of ZnSe-like LO phon...
