X raydiffractometer xrd

Manufactured by Philips

The X-raydiffractometer (XRD) is a laboratory instrument designed to analyze the structure and composition of solid materials. It utilizes the principles of X-ray diffraction to provide information about the crystallographic structure, chemical composition, and physical properties of a sample.

Characterization of Cobalt Hydroxide Nanosheets

A field emission scanning
electron microscope (FE-SEM, Carl Zeiss Sigma VP, Germany) and a high-resolution
transmission electron microscope (HR-TEM, JEM-2100 (HRP)) were utilized
to analyze the morphology of the synthesized Co(OH)₂ NS.
HR-TEM was used to characterize the selected area diffraction pattern
(SAED) and the lattice fringe of the Co(OH)₂ NS. An X-ray
diffractometer (XRD, Philips) with a Cu Kα radiation (λ
= 1.5406 Å) and a Fourier transform infrared (FTIR) spectrophotometer
(MIDAC, M4000) were used to characterize the structural properties
of Co(OH)₂ NS. To calculate IC₅₀ values, luminescence
was read with a Tecan infinite M1000 Pro instrument (Tecan, Männedorf,
Switzerland). Annexin V was evaluated with a BD FACSCantoII instrument
(BD Biosciences, San Jose, CA). Fluorescence images were capture with
a Nikon Ti Eclipse inverted microscope (Nikon, Minato City, Tokyo,
Japan).

Synthesis and Characterization of Glass Ionomer-Fluoroapatite Nanocomposite

Check if the same lab product or an alternative is used in the 5 most similar protocols

In order to prepare glass ionomer-fluoroapatite nanocomposite, 0, 1, 3 and 5 wt% of nano-FA (~ 70 nm) were added to the synthesized glass ionomer powders and mixed in amalgamator for 30 s,
separately. Then, GI-FA powders were mixed with polyacrylic acid for 30 s, where the powder/liquid (P/L) ratio was set at 2.7/1. After that, cement mixes were poured into the aluminum moulds
(4 mm in diameter and 6 mm in height). The moulds were covered with glass slides, flattened and gently pressed by hand to remove air bubbles from the cements. Finally, after 1 h, the specimens were carefully removed.
The phase composition of samples was carried out by the Philips X-ray diffractometer (XRD) with Cu Kα radiation (λ=0.154 nm) at 40 kV and 30 mA.

Urchin Spine Calcite Mineralogy Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols

X-ray diffractometry (XRD) was used to analyse the carbonate mineralogy (wt% MgCO3) of six Paracentrotus lividus from each site. The tests were cleaned of internal organs, rinsed with distilled water, soaked in a mild bleach solution and dried at 60 °C for three days. For XRD, approximately 0.5g of each sample was placed in a clean mortar, with 0.1g of analytical grade halite (NaCl) as an internal standard, and ground to a fine powder until it was consistent in colour and texture. A small amount of 95% ethanol was added to make a slurry which was smeared uniformly on a glass slide and left to air dry. Each sample was scanned by a Phillips X-Ray diffractometer (XRD) between 26 and 33 °2q. There was 1 count per degree, and the count time was 1 second. Calcite peak position was corrected based on the internal standard halite peak, and then a machine-specific calibration for determining Mg content was applied: y = 30x -882, where y = wt% MgCO3 in calcite and x = calcite peak position in °2q (after Gray & Smith, 2004) (link). For each urchin three spines and three test plates were analysed and the mean wt% MgCO3 of the three measures was used as the independent datum for statistical analysis.

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.
