An enhancement in structural and superconducting properties of Bi2212 epitaxial thin films grown by the Pechini sol–gel method

Bi₂Sr₂CaCu₂O_8+δ (Bi2212) thin films with excellent superconducting properties were prepared by the Pechini sol–gel method using nitrates as reactants.

A microstructural and crystallographic investigation of the precipitation behaviour of a primary Al₃Zr phase under a high magnetic field

A high magnetic field has a significant microstructural and crystallographic effect on the primary Al₃Zr phase precipitated during the solidification of an Al-Zr alloy.

Tunnel-dependent supercapacitance of MnO₂: effects of crystal structure

The geometric distribution of Mn active centers during Faradaic reaction was quantitatively calculated on the basis of four different kinds of MnO₂ crystallographic structures, which can be confirmed by our experimental supercapacitance evaluations of these four kinds of MnO₂ samples.

Interfacial morphology of low-voltage anodic aluminium oxide

Neutron and X-ray reflectivity, as well as small-angle scattering, are used to probe the in-plane and surface-normal structure of anodized aluminium. A new low-voltage anodization protocol gives smooth anodic films on aluminium, suitable for investigation by neutron and X-ray reflectivity.

Multiple twinning in pure hexagonal close-packed titanium

A study of multiple twins in commercial pure titanium evidenced the influence of twinning order on the multiple twin variant, the role of the normalized Schmid factor in the twin variant selection, and the critical condition of twinning being activated by another twin in a neighbouring grain.
