SAXS Analysis of Starch Samples

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

SAXS experiments were performed on a SAXSess small-angle X-ray scattering system (Anton-Paar, Austria) equipped with a PW3830 X-ray generator (PANalytical), operated at 50 mA and 40 kV, using Cu-Kα radiation with a wavelength of 0.1542 nm as the X-ray source. The samples (ca. 60% MC) used for the SAXS measurement were prepared by premixing the starches with added water in glass vials and were equilibrated at 20 °C for 24 h before the analysis. Each sample was placed in a paste sample cell and was exposed at the incident X-ray monochromatic beam for 5 min.
The data, recorded using an image plate, were collected by the IP Reader software with a PerkinElmer storage phosphor system. All data were normalized, and the background intensity and smeared intensity were removed using the SAXSquant 3.0 software for further analysis.

X-ray diffraction patterns were collected
in reflection using a Philips-Norelco wide-range goniometer and scintillation
counter, equipped with an Advanced Materials Research graphite focusing
monochromator. Cu Kα radiation (λ = 0.15418 nm) was produced
via a PANalytical PW3830 X-ray generator with a long-fine-focus Cu
tube. Angular calibrations were performed using a quartz reference
standard. Samples were deposited as a loose powder (∼0.5 mm

crystallinity was assessed by the presence or absence of strong Bragg
reflections.³⁵

The phase transformation of SPTS from semisolid to liquid and from precursor to gel was comprehensively explored by visual, polarized light microscope (PLM, Mshot Instruments Ltd, Guangzhou, China) and small angle X-ray scattering (SAXS, SAXSee, Anton Paar, UK) method. For the visual test, each SPTS@hard capsules was placed in vials with 5 mL distilled water or hydrochloric acid solution (pH 1.2) under 37 ± 0.5 °C. Changes of appearance at certain time intervals were photographic recorded.
The dynamic phase transformation process of SPTSs upon contacting with distilled water or PBS was observed with PLM at 37 ± 0.5 °C by observing the birefringence texture. SPTS@hard capsules of DOXY and MLX were withdrawn from distilled water and PBS respectively at different time intervals. The photographs were taken using a MD50 digital camera.
The crystalline structures of the SPTSs were characterized by the SAXS at 37 ± 0.5 °C. Samples were measured at 50 mA and 40 kV using a PW3830 X-ray generator (PANalytical) with the X-ray source of Cu Kα radiation (λ = 0.1542 nm). The intensity versus scattering factor (q) was recorded.

where θ means the scattering angle.

SAXS Analysis of Nanocomposite Films

The nanocomposites were cut into strips for SAXS experiment using a SAXSess camera (Anton-Paar, Graz, Austria). A PW3830 X-ray generator with a long fine focus sealed glass X-ray tube (PANalytical) was utilized, and the operating voltage and current were 40 kV and 50 mA, respectively. A block collimator provided an intense monochromatic primary beam (Cu-Kα, λ = 0.1542 nm). The films were placed in the sample holder along the line shape X-ray beam in the evacuated camera housing. The sample-to-detector distance was 261.2 mm, and the temperature was kept at 26.0 °C. The 2D data were integrated into the one-dimensional scattering function I(q), as a function of the magnitude of the scattering vector q defined as Equation (1):
λ is the wavelength and 2θ is the scattering angle. Each measurement was collected for 5 min. All I(q) data were normalized to have the uniform primary intensity at q = 0 for transmission calibration. Desmearing was necessary because of the line collimation.

SAXS Analysis of Lyotropic Liquid Crystals

SAXS measurements were performed using a SAXSess camera (Anton Parr, Austria) attached to a PW3830 X-ray generator (PANalytical, The Netherlands) , which was operated at 40 kV and 50 mA, with a sealed-tube anode (Cu-Kα wavelength of 0.154 nm) . The measurements were carried out at room temperature. Two-dimensional scattering patterns recorded on an image plate detector were read out by a Cyclone system (Perkin-Elmer, Downers Grove, IL, USA) and were converted into one-dimensional curves as a function of the scattering vector, q＝ (4π/λ ) sin (θ /2) , where θ is the total scattering angle, with SAXSQuant software (Anton Paar) . All scattering intensities were transmission calibrated by adjusting the attenuated primary intensity at q＝0 to unity and corrected for the background scattering of the sample cell and solvent. The SAXS peak ratio was used to confirm the type of the lyotropic liquid crystals.

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.
