Powdered XRD (Panalytical diffractometer) using Cu-Kα radiations was used to identify the phase purity and structural details of the synthesized materials. The data were collected over the 2θ angular range of 10–90° with a step size of 0.01°. The morphology (particle size, shape, distribution) and elemental mapping of the synthesize materials were under taken using scanning electron microscopy (SEM, NOVA NANOSEM 450). Thermal stability of the synthesized materials was studied using thermogravimetric analysis (Perkin Elmer, TGA 4000) from room temperature to 500 °C at the heating rate of 10 °C in a N2 atmosphere. Fourier-transform infrared spectroscopy (Perkin Elmer Frontier FT-IR) was further used to confirm the phase purity using KBr pellet method in the range of 500–2500 cm−1 wave numbers. The activity of redox couples was studied through X-ray Photoelectron spectroscopy (XPS) (Thermo-Scientific-Sigma Probe).

Lard and other animal body fats from meat such as chicken fat, beef fat, and mutton fat were extracted according to the method stated by [34 ], with little variation. All samples were gradually heated from 50 °C to 150 °C for 45 min until the fat was extracted from all the samples on the petri dish. The discharged fat was then filtered as the concentration contained solid minute particles. Moreover, samples were centrifuged at 3000 rpm for 20 min and filtered through Whatman filter paper. Pure fats produced by the extraction process were then used to make adulterated samples. All the chemicals used in this experiment were of analytical consistency. Pure and adulterated fats were then analyzed using FTIR spectroscopy. The instrument used was Frontier FT-IR by PerkinElmer. The optical system with KBr beam splitter was used to enable quality data collection over a range of 8300–350 cm−1 at a best resolution of 0.4 cm. The resulting spectrum contained 2500 continuous values for one sample, with intervals of 0.8 cm−1. To guarantee that there was no major fluctuation between each spectra scanned, each spectrum was recorded at the same temperature. This procedure was required to remove any uncontrolled ambient influences on the instrument and the sample.

The resins of SL/FA 1:1 and 4:1 as well as the polymer T/FA 1:1 and 4:1 were produced with 1.5% sulfuric acid at the temperature of 100 °C. The solid spent liquor and the tannin were produced adding 1.5% sulfuric acid to a 60% solution and drying them at 100 °C for 2 h. The homo-polymer of furfuryl alcohol, the poly(furfuryl alcohol) (PFA), was produced by adding a few drops of sulfuric acid to 3 g of furfuryl alcohol. The black polymer, obtained within a few minutes through strong exothermic polymerization, was dried at 60 °C for 2 h. Every solid fraction was finely milled and scanned with a Frontier FT-IR from Perkin-Elmer (Waltham, MA, USA) equipped with ATR miracle device. The spectra were registered between 4000 and 600 cm−1 with 32 scans at resolution of 4 cm−1. Each sample was scanned three times and the average spectrum was used for this study. The software Unscrambler X (Camo) (Oslo, Norway) was used for the analysis of data. The spectra were all studied in the region between 1800 and 600 cm−1, baseline corrected, and area normalized before being elaborated for the principal component analysis (PCA) performed with the algorithm NIPALS (NonLinear Iterative Partial Least Squares).

The crystal composition of homozygous crystallin mutant lenses was determined by Attenuated Total Internal Reflection Fourier-transform infrared microspectroscopy (ATR-μFTIR). The unstained tissue sections were imaged using the visible CCD camera and frame grabber on the Spectrum Spotlight (61 ). Infrared images over the selected area were collected with a PerkinElmer Spotlight 400 infrared microscope interfaced to a PerkinElmer Frontier FTIR. The system employed a 16 × 1, liquid nitrogen–cooled, mercury cadmium telluride (HgCdTe) array detector. The ATR imaging accessory is based on a germanium internal reflection element which enables infrared spectra to be collected at a pixel resolution of 1.56 μm. Each spectrum in the image represents the average of four individual scans collected at a spectral resolution of eight wavenumbers (cm−1).

The chemicals are analytical-grade reagents and were used without further purification. A Bruker D8 ADVANCE X-ray diffractometer was used to collect the X-ray diffraction patterns of all samples using Cu Kα radiation (40 kV, 40 mA, λ = 1.5418 Å). Nitrogen adsorption−desorption was determined with a MicrotracBEL BELSORP-mini X at −196 °C. The samples were activated at 150 °C for 24 h under a vacuum before adsorption experiments. After sensing measurement, MOF pellets were ground into a fine powder with a mortar for FTIR and UV–Vis characterization. UV–Vis absorption spectra were collected on a PerkinElmer Lambda 1050 spectrophotometer. FTIR spectra were measured by a PerkinElmer frontier FT-IR in attenuated total reflectance (ATR) mode with a KBr window. High-resolution mass spectra of adsorbed VOCs were measured on Bruker Compact (APCI Q-TOF mode) and Bruker Autoflex speed (MALDI-TOF mode). The adsorbed VOCs were extracted from the MOFs by using dichloromethane. The impedance measurements were performed using an Autolab PGSTAT302 N equipped with FRA32 M module (Metrohm) over the frequency range of 1 Hz to 1 MHz with an input voltage amplitude of 300 mV and the current range of 1 mA. Impedance values were measured from Nyquist plots of MIL-100(Al, Fe) before and after VOC adsorption of preparation. Impedance data analysis was performed on NOVA software.
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.
