X-ray Diffraction Analysis of Cu2+ Doped Zn1-xCuxFe2O4 Spinel Nanoparticles using Williamson-Hall Plot Method

, 2019
The nanoparticles (NPs) of Zn1-xCuxFe2O4 (ZCFO) spinels with x = 0, 0.2, 0.4, 0.6 and 0.8 were synthesized by a sol-gel combustion method using acetate precursor. The NPs of ZCFO were prepared by following calcination process at 600C for 8hrs.

Quantitative Analysis of Mineral Composition of Kyanite by X-ray Diffraction with Rietveld Refinement Method

Yankuang ceshi, 2019
BACKGROUND The content of minerals in kyanite can be analyzed by chemical phase method, but the analytical process is very tedious. Moreover, the existence of heteromorphism and refractory minerals can affect the accuracy of analysis results. An internal

Care, Social Practices and Normativity. Inner Struggle versus Panglossian Rule-Following [PDF]

, 2019
Contrary to the popular assumption that linguistically mediated social practices constitute the normativity of action (Kiverstein and Rietveld, 2015; Rietveld, 2008a,b; Rietveld and Kiverstein, 2014), I argue that it is affective care for oneself and ...
