Sentence examples for precipitate aging from inspiring English sources

A schematic model of the structural characteristics of Cu/ZnO catalysts as a function of precipitate aging is proposed.

Moreover, continuous precipitate aging led to a decreasing amount of Zn in the copper clusters of the Cu/ZnO catalysts.

Structural modifications of Cu/ZnO catalysts for methanol steam reforming (MSR) as a function of precipitate aging in catalysts preparation process has been investigated comparatively.

Accordingly, it follows that long term L consumption might precipitate aging mechanisms in arterial vessels in susceptible hosts.

The precipitate aged for 15 months was found to give an essentially lower Mössbauer effect.
