Characterizing Porous Oxides using XRD and BET

Check if the same lab product or an alternative is used in the 5 most similar protocols
An X'Pert PRO diffractometer (X'Pert PRO, PANalytical B.V.) equipped with a Cu Kα radiation source (40 kV and 40 mA) was used to obtain X-ray diffraction (XRD) patterns of the OCs. The OCs were scanned at a rate of 2° min−1 from 2θ = 10° to 80° with a scanning step of 0.02°. N2 adsorption–desorption isotherms and pore-diameter distribution at −196 °C were measured using a Micrometrics ASAP 2010 system. The specific surface areas were calculated by the Brunauer–Emmett–Teller (BET) method. The surface morphology of the OCs was obtained using environmental scanning electron microscopy (ESEM; FEI Quanta 200) in conjunction with energy-dispersive X-ray spectroscopy (EDS). H2-TPR was conducted in an AutoChem II 2920. First, the sample (about 0.20 g) was heated to 300 °C at a rate of 10 °C min−1 in helium (50 mL min−1) and kept for 3 h. After being cooled to 50 °C, helium was replaced by a gas mixture consisting of 10/90H2/Ar v/v% (50 mL min−1), and the sample was reheated to 900 °C at a rate of 10 °C min−1.

X-ray Diffraction Analysis of Polymorphic Drug Crystals

Check if the same lab product or an alternative is used in the 5 most similar protocols
The X-ray diffractograms of ASP-I, ASP-II, and ASP-III were obtained by using an X-ray diffractometer (PAN analytical's X' Pert PRO, The Netherlands), equipped with X' Pert PRO data collector software. The radiations used were generated by CuKα -1 source fitted with a filter made up of nickel metal, and the instrument was operated at a voltage of 45 KV. The drug crystals were packed into the holder and gently pressed by the glass slide to ensure the co-planarity between the samples and the surface of the sample holder. Samples were scanned for 2θ values over the range of 5-45°at a scanning rate of 10°/min to get the X-ray diffractograms.

In order to obtain nanocomposite structure, as-spun ribbons with amorphous structure were annealed at a temperature of 650 °C for 10 to 20 min. The phase constitution was identified by X-ray diffraction with a Cu-Kα source (XRD, X’ Pert Pro, PANalytical, Malvern, UK).

Determining Quercetin Crystal Morphology

Check if the same lab product or an alternative is used in the 5 most similar protocols
PXRD was used to confirm
the quercetin solid form and identify the morphologically dominant
facets in the crystals analyzed. This was estimated by a comparison
of the experimental and predicted diffractogram from the crystal structure,
where the reflection that was significantly enhanced in the experiment
as compared to the theoretical was assumed to be the dominant plane.
PXRD patterns were collected on a Panalytical X’Pert PRO that
was set up in Bragg–Brentano mode, using Cu Kα radiation
(λ = 1.54184 Å), in a scan between 5 and 50° in 2θ
with a step size of 0.032° and time per step of 25 s.

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.
