Thermal analysis measurements were performed with a Perkin Elmer Diamond DSC device (Waltham, MA, USA) with a heating/cooling rate of 1 K min−1 on a temperature interval between 293 K and 550 K. The measurements were made in an inert gas atmosphere, argon, at a flow rate of 20 mL min−1. The instrument has been calibrated for specific parameters, temperature, and enthalpy using high purity indium (ΔfusH = 28.54 J g−1). All samples’ masses were between 7 and 10 mg and were weighed with the Partner XA balance (Radwag, Radom, Poland) with a precision of 10 μg.
The XRD measurements for the crystalline structure of the samples were studied by X-Ray Diffraction using a D8 Advance Bruker diffractometer (Cu Kα radiation λ = 1.5418 Å, 40 kV, 40 mA, Bragg-Bretano geometry, Karlsruhe, Germany) at a scanning speed of 0.10 degrees/min in the 10–40 degrees 2Θ range. Crystallite size was estimated with Scherrer equation.
All the FTIR measurements were performed on a Perkin Elmer Spectrum Two ATR-FTIR (Waltham, MA, USA) with a data acquisition count set to 100. The spectrometer was equipped with an universal attenuated total reflection (UATR) accessory containing a diamond/ZnSe crystal for 1 reflection analysis. FT-IR spectra were recorded at a 4 cm−1 spectral resolution.

Protein concentration was measured by the Lowry protein assay by Folin reaction (Lowry et al. 1951 (link)). The determinations of complex uronic acid-bearing native and degraded HA were estimated by the carbazole assay (Cesaretti et al. 2003 ). The pH of the samples was measured using a pH meter, which was calibrated with pH 7 and pH 4 buffer.
Functional groups were identified using the Perkin Elmer Spectrum Two ATR-FTIR, over the wave number ranging from 4000 to 450 cm−1.
UV–vis absorption spectra were carried out using a UV–vis recording spectrophotometer (UV-2501PC). Distilled water was used as a reference.

1H-NMR and 13C-NMR data were obtained using 360 MHz or 500 MHz Bruker Avance instruments. FT-IR data were collected on a Perkin Elmer Spectrum Two ATR FT-IR (Shelton, CT, USA). The thermal stabilities of these PI-ionenes with ILs were evaluated by thermogravimetric analysis (TGA) at a heating rate of 10 °C min−1 under an N2 atmosphere (Seiko TG/DTA 7300). The glass transition temperature (Tg) of each PI-ionene was observed by DSC (TA Instruments, DSC Q20) from 20 to 300 °C with a scan rate of 10 °C min−1 under N2. The wide-angle X-ray diffraction (WAXD) patterns of the materials were measured using a Bruker D8 Discover diffractometer by employing a scanning rate of 4° min−1 in a 2θ range from 5° to 70° with a Co Kα1 X-ray (λ = 0.17886 nm) source. The d-spacing values were calculated using Bragg’s law (d = λ/2sin θ) and the Diffrac-EVA software. The number average molecular weight (MN) values of the PI-ionenes were determined via MALDI-TOF MS (Bruker Ultraflex).

Investigations were conducted on the effects of irradiation on the optical, morphological, and structural characteristics of the green synthesized BaO NPs utilizing XRD, FTIR, UV–vis–NIR spectrophotometer technique and FESEM. The thermally annealed sample was analyzed using an X-ray diffractometer (3040-X'Pert PRO, Philips) using CuKα radiation of wavelength 1.54056 Å, where 2θ = 10°–80°, operating voltage = 40 kV, current = 30 mA, and scanning speed = 1° min−1. FTIR (Model: FTIR-ATR PerkinElmer Spectrum Two) was used to conduct functional group and phase stability studies for wavenumbers between 2000 and 400 cm-1. FESEM (Model-JSM-6700F, JEOL Ltd., Tokyo, Japan) was utilized to look into the distribution of particle sizes and morphological properties of BaO NPs. The UV–Vis–NIR spectroscopy data (Model: PerkinElmer UV–Vis_NIR spectrometer Lambda 1050) data were used to calculate the optical bandgap using the reflected spectra in the 200–800 nm wavelength range.

To compare the changes generated in the polymer matrix by the addition of different concentrations of LCNF, the FTIR spectra of each of the films obtained were analysed. For that end, FTIR spectra were obtained using the FTIR-ATR PerkinElmer Spectrum Two (Waltham, MA, USA) with a resolution of 4 cm−1 in the range 450–4000 cm−1, performing 40 scans per sample.
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.
