The NPs synthesized were characterized by different techniques. The structural characterization of the NPs was performed by X-ray powder diffraction analysis using a D8 Advance diffractometer (Rigaku, Tokyo, Japan) equipped with Ge (111) monochromator, CuKα1 radiation, and LynxEye superspeed position detector. The aspects of the NPs obtained were analyzed using scanning/transmission electron microscope, STEM HITACHI HD2700 (HITACHI, Tokyo, Japan), from LIME-INCDTIM, Cluj-Napoca, Romania, cold field emission, operated at 200 kV and coupled with double cut EDX (energy-dispersive X-ray spectroscopy) system, operated at 10−7 pressure. It was used to confirm the elemental distribution in the NPs, and the size distribution was analyzed using Image J (version Java 8). FTIR measurements were performed with a JASCO 6100 FTIR spectrometer (JASCO Deutschland GmbH, Pfungstadt, Germany) in the 4000–400 cm−1 spectral domain with a resolution of 4 cm−1 by using the KBr pellet technique [34 (link)].
6100 ftir spectrometer
Manufactured by Jasco
Sourced in Germany, Japan
The JASCO 6100 FTIR spectrometer is a Fourier Transform Infrared (FTIR) spectroscopy instrument designed for quantitative and qualitative analysis of organic and inorganic compounds. It measures the absorption of infrared radiation by a sample to obtain its infrared spectrum, which can be used to identify and characterize the chemical composition of the sample.

The Ag-MnO2 nanoparticles obtained were characterized through scanning-transmission electron microscopy (S/TEM), X-ray diffraction (XRD), and Fourier-transformed infrared spectroscopy (FTIR). S/TEM was performed using S/TEM HITACHI HD2700 cold field emission, operated at 200 kV (HITACHI, Tokyo, Japan), and coupled with EDX (Oxford Instruments, Oxford, UK, AZtec Software, version 3.3) used for elemental detection. The size distribution of nanoparticles was determined using Image J software (version Java 8). XRD analysis was recorded using high resolution SmartLab X-ray diffractometer (Rigaku, Tokyo, Japan) operated at 9 kW and coupled with SmartLab Guidance software (SmartLab Studio II package software). FTIR measurements were performed with a JASCO 6100 FTIR spectrometer (JASCO Deutschland GmbH, Pfungstadt, Germany) in the 4000–400 cm−1 spectral domain with a resolution of 4 cm−1 by using the KBr (for IR spectroscopy, Merck KGaA, Darmstadt, Germany) pellet technique.

Thymol, Eudragit RS-30D, P-188, CTAB, and thymol-loaded CPNPs were analyzed using a JASCO 6100 FT-IR spectrometer (JASCO, Tokyo, Japan). The examined samples were added to potassium bromide before being squeezed in a hydraulic press at 200 kg/cm2 for 3 min. Each sample was scanned counter to a blank.

Sodium alginate beads were prepared by a slightly modified method by Rijo et al. [22 (link)]. An amount of 0.6 g of sodium alginate (Alg) was stirred with 20 mL of ultrapure water for 1 h at 400 rpm at 40 °C, then cooled to room temperature, when 10 mL of extract was added under stirring. The mixture was stirred for 10 min and the resulting solution was added by means of a syringe to a solution of 0.2 M CaCl2. The addition was carried out for 20 min under continuous stirring, after which the mixture was left to stir for another 15 min, then it was washed three times with ultrapure water. The obtained beads were lyophilized.
For the morphological examination of the microencapsulated rosemary extract (MRE) and microencapsulated summer savory extract (MSE) a scanning electron microscope SEM Hitachi SU8230 (Hitachi, Tokyo, Japan) was used.
FT–IR spectra were recorded using a JASCO 6100 FTIR spectrometer ((JASCO International Co., Ltd., Tokyo, Japan) in the 4000 to 400 cm−1 spectral range, with 4 cm−1 resolution by the KBr pellet technique. Each sample has been dispersed in about 300 mg of anhydrous KBr mixed in an agate mortar. The pellets were obtained by pressing the mixture into an evacuated die. The spectra were collected and analyzed with Jasco Spectra Manager v.2 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.
