Efficient Pb (II) removal from wastewater by TEG coated Fe3O4 ferrofluid [PDF]
Tri-ethylene glycol (TEG) coated Fe3O4 nanoparticles ferrofluid were used for Pb (II) removal from simulated wastewater. The samples were synthesized using a modified co-precipitation method.

The Rietveld Method ? A Historical Perspective [PDF]
differences between observed and calculated values was already well established in crystallography. From there it was, in retrospect, only a small step to refrain from using the integrated intensities as observed values but to use the actual measured profile intensities obtained by step scanning the powder diagram.

An insight into the thermal properties of struvite-k by Rietveld refinement method
This work investigated the thermal properties of struvite-k (a main binding phase and a strength-giving mineral from the magnesium potassium phosphate cements) exposed to different conditions by Rietveld Refinement Method coupled with X-ray diffraction ...

Rietveld Refinement Analysis of Lampung Natural Zeolite Catalyst Impregnated Fe with Diffraction Method Using MAUD Software [PDF]
This research characterizes the space group and R-phase crystal structure using the XRD method and Rietveld refinement. Rietveld improvements using the Material Analysis Using Diffraction (MAUD) software are acceptable if the Rwp < 15% and Sig < 2%. MAUD
