Check if the same lab product or an alternative is used in the 5 most similar protocols
The influence of sandblasting and plasma irradiation using different gas species on crystalline structure of the zirconia specimens was analyzed using a θ–2θ XRD (SmartLab, Rigaku, Tokyo, Japan). The specimens used in the analysis of surface topography were subjected to XRD analysis (i.e., seven groups and n = 3 for each group). Diffractograms with Cu-Kα radiation were obtained from 27° to 33° at a scan speed of 10°/min and a step size of 0.02°. The monoclinic volume fraction, Vm, was calculated using the Garvie and Nicholson method modified by Toraya [19 (link),20 ],


where It and Im represent the integrated intensity of the tetragonal (101) and monoclinic (111) and (−111) peaks. The integrated intensity of each peak was calculated using the device software (PDXL2, Rigaku). The results were analyzed using Tukey’s test.

The quantitative analysis was performed based on the Rietveld refinement and an ab-initio crystal structure determination using crystal structure information of α-chitin provided by the software. The degree of acetylation (DA) of chitin [21 (link)] was calculated by: DA (%)=100(103.97CrI)0.7529

X-Ray diffraction (XRD) was used to define the crystal structure of ENM powders. The XRD patterns of ZnO and CuO ENMs were collected in 2θ at 10−90° configuration with a 0.02° increment and 2s step. Collected data were analyzed by EVA software by BRUKER©. For Ga2O3 ENM, XRD measurements were performed with a Rigaku Miniflex in a silicon low background holder and with a 1.25° divergence slit. The diffractograms were then analyzed in Rigaku’s PDXL2 and Rietveld refinement performed where appropriate.

Characterization of C-S-H Gel Phases

Check if the same lab product or an alternative is used in the 5 most similar protocols
XRD analyses of Cm(III)-free C-S-H gel samples before and after leaching were performed to characterize the solid phases including secondary phases formed due to leaching. The diffractograms were collected with a MiniFlex 600 diffractometer (Rigaku, Tokyo, Japan) equipped with a Cu X-ray source (40 keV/15 mA operation for X-ray generation) and the D/teX Ultra 1D silicon strip detector in the Bragg-Brentano θ-2θ geometry at a scanning speed of 0.6° per min. The samples were mounted as wet pastes on a zero-background Si sample holder and stored for several minutes in an inert gas atmosphere to remove excess water from the samples and thus, to minimize carbonation of the samples during measurements. The subsequent Rietveld analysis of diffractograms was done with the program PDXL 2 (Rigaku) and the ICDD PDF-4+ 2016 database (C-S-H phase (database card number 00-033-0306), portlandite (database card number 01-083-4600), calcite (database card number 01-083-4601), aragonite (database card number 01-075-9985), vaterite (database card number 04-017-8634) and halite (database card number 00-005-0628)).

All samples were prepared by a solid state reaction of LiMn 2 O 4 (Alfa Aesar) and Li 2 CO 3 (Sigma Aldrich). The LiMn 2 O 4 powder was thoroughly mixed with the proportional amount of Li 2 CO 3 in order to obtain the desired stoichiometry of Li 1+y Mn 2Ày O 4 . The mixture was heated up in a tube furnace to 600 1C for 18 h in air with a heating and cooling rate of 7 1C min À1 . Table 1 gives an overview of the synthesis conditions, the nominal amount of lithium from the synthesis and the lattice constants a of the samples, determined by X-ray diffraction (XRD) measurements.
Diffraction data was collected on a Rigaku Smartlab 9 kW using Cu Ka radiation (l = 1.54 Å) over a 2y range of 15-901 in Bragg-Brentano geometry with a step size of 0.011. The lattice parameters were determined from the XRD pattern using the Rigaku PDXL 2, based on the crystal structure reported by Berg et al. (ICSD 50415). 45

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
