The morphological features and mesoporous network structure of the as-synthesized NPs were examined using FESEM (field emission scanning electron microscope) images (FEI Talos F200S). The elemental compositions of the samples were determined using elemental mapping and EDS (energy-dispersive spectroscopy) analyses. The BET (Brunauer–Emmett–Teller) surface area, total pore volume, and pore diameter were obtained using nitrogen sorption isotherms (Micromeritics ASAP-2460, Norcross, GA, United States). The FT-IR spectra were examined using a FT-IR spectrometer (FT-IR 6800 JASCO, Marseille, France) in the 400–4000 cm−1 region using the KBr pellet technique. The zeta potential and size were recorded with a Nano-z90 Nanosizer (Malvern Instruments Ltd., Worcestershire, UK) at ambient temperature.

We used FTIR-6800 (JASCO) to
measure IR spectra. To improve measurement efficiency, a measurement
method was applied to acquire absorbance at multiple wavelengths at
once by continuously irradiating infrared light, followed by Fourier
transforming the interference patterns caused by the sample. For each
sample, a total of 32 cumulative scans were taken in the attenuated
total reflection mode with a resolution of 1 cm–1 and a frequency range of 4000 to 600 cm–1.

The selected wild mushroom samples were dried and mixed with FT-IR grade potassium bromide (1:20; 0.02 of sample with KBr at a final weight of 0.4 g). The samples were grounded in agate pestle and mortar for obtaining pellets by hydraulic press. The absorbance Fourier transform infrared (FT-IR) spectra of the samples were recorded using JASCO FT-IR 6800 within the scanning range of 400–4000 cm-1 and 64 scans per second were recorded [47 ].

To clarify the interaction between Lut and excipients, FTIR was applied to ensure the structure of Lut did not change, which may cause the loss of activity. The FTIR system was FT/IR-6800 (JASCO, Inc., Tokyo, Japan). Lut and KBr were dried overnight and mixed in a 1:100 (w/w) ratio, followed by grinding and compressing into a tablet. Excipients and F7 were analyzed by ATR, and air was used as the control group. The range of wavelength was evaluated at 600–4000 cm−1.

The deoxygenated liquid products were filtrated to remove the catalyst
and were subsequently analyzed by a gas chromatography (GC) system
equipped and a flame ionization detector (FID) (Clarus 580, Perkin
Elmer) with a capillary column (DB-1HT, 30 m × 0.32 mm ×
0.1 μm). The quantities of n-alkanes ranging
from n-C8 to n-C18 and unreacted triglycerides (TGs) in the liquid product
were calculated using the calibration curves of n-alkane and triglyceride standards. The GC conditions were similar
to those of a previous study.1 (link),7 (link),11 (link) The triglyceride conversion, gasoline yield, and diesel yield were
defined by the following equations To directly evaluate the involvement of hydrodeoxygenation (HDO),
decarbonylation, and decarboxylation (DeCO/DeCO2) reactions,
the percent relative involvements of HDO and DeCO/DeCO2 reactions were calculated usingeqs 4 and 5 . In addition, the n-alkane
product distribution of each component was calculated according to
a previous study52 (link) usingeq 6 . Furthermore, to confirm the
deoxygenation activities under solvent-free conditions, the functional
groups of the refined palm oil, n-alkane standard,
and products were identified by Fourier transform infrared (FTIR)
spectroscopy (Jasco FT/IR 6800).

Solutions of monomeric phenols (2 mM) were prepared in 100 mM sodium phosphate buffer at pH 6.5 by following the prescribed method [33 (link)]. The monomers used were catechol, p-hydroxybenzoic acid, ferulic acid, and salicylic acid. Separately, a standard tyrosinase (10 U.mL− 1) from mushroom and an extracellular protein from B. aryabhattai TFG5 were compared. A negative control without the tyrosinase enzyme was also used. The pH was adjusted to 6.5 by adding NaOH. The steps were performed in sequence, and one among 1 mL of buffer, 3.5 mL of the buffered monomer solution, and 0.5 mL of the buffered tyrosinase solution was added to a 15 mL tube to reach a final volume of 5 mL, followed by incubation in the dark for one week. After mixing the solution, 1 mL aliquot was retrieved and centrifuged at 11,200 ×g for 10 min in a refrigerated centrifuge (Thermo Fisher, India) at 4 °C. The FT-IR spectra were obtained by scanning the liquid samples in ATR- FTIR (FTIR–6800 JASCO, Japan). The transmittance spectra were recorded in the wavenumber range of 4000–400 cm− 1 with a spectral resolution of 4 cm− 1 and 32 scans per sample [34 (link)].
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.
