For powder X-ray diffraction (XRD) experiments, the catalyst samples were placed on an XRD holder, and measurements were performed with a Bruker D8 Advance X-ray diffractometer between 5 and 80°. Raman spectra were collected using a Horiba Jobin Yvon Modular Raman spectrometer. A 660 nm laser with a 1200 mm−1 grating, 1% filter and a 50x objective was used and spectra of multiple particles were measured at ambient temperature. A silicon wafer was used to calibrate the Raman shifts. Field emission scanning electron microscopy (FESEM) was performed on a JEM-6700F (JEOL) microscopy with an acceleration voltage of 5 kV in the secondary electron image mode. The elemental composition in the catalyst samples was measured using ICP-OES analysis.
Both the quantitative and qualitative analysis (MassHunter Workstation Software) of the oil samples were performed using a 5975C GC/MS (Agilent Technologies Inc) with a Triple Axis Detector and an HP-5 capillary column. Dilute oil samples were filtered through a 0.05 μm PCTE membrane filter. Sample injection volumes were 5 μL and the temperature program was set as follows: 50 °C to 300 °C (3 °C min−1). FAMEs and TG concentration were identified by the internal standard method and the NIST 98 mass spectrometry database. The acid value, HHVs and viscosity were determined via titration, bomb calorimetry and viscometry, respectively.

Samples of NC, MNC, MNC/PES fibers, and MNC/PES-AOL biocatalysts were subjected to FTIR analysis (Perkin Elmer: Frontier 100; Waltham, MA, USA). The spectrum was recorded in transmission mode from 400–4000 cm−1 with a resolution of 4 cm−1. Next, the Raman LabRAM HR Evolution (Horiba Scientific, Kyoto, Japan) equipped with a 785 nm solid-state laser captured the spectra of MNC and MNC/PES fibers and MNC/PES-AOL between 100–2000 cm−1 at ambient temperature (12 mW). A 100× eyepiece microprobe focused the laser, and a charge-coupled device chamber detector identified the scattered beam with a 3 cm−1 spectral resolution. FESEM micrographs of MNC/PES fibers and MNC/PES-AOL were recorded on a JEOL JEM-6700F operating at 5 kV and 10 μA. The samples were first mounted on a silicon wafer and sputter-coated with a thin film of gold to avoid charging under the electron beam. Elemental compositions were determined using EDX spectroscopy. Thermogravimetric and differential thermal gravimetric thermograms of MNC and MNC/PES fibers and MNC/PES-AOL were obtained on the Thermogravimetric Analyzer (Q500-2164: Perkin Elmer, Waltham, MA, USA). Each sample was inserted into a compact ceramic alumina crucible and heated from 30 °C to 1000 °C under N2 flow (5 °C/min).

The strut microstructures and the average strut and pore size of the scaffolds were measured through scanning electron microscopy (SEM, JEM-6700F; JEOL). The porosity (macro pores) was measured by Archimedes method in deionized water at room temperature. The ceramic scaffolds were weighed as dry weight (W1). Then the scaffolds were immersed in a beaker of water and held under vacuum to make the liquid into the pores until no bubbles emerged from the scaffolds. Subsequently, the samples were re-weighed under water to produce the suspension weight (W2). Afterwards, the scaffolds were carefully taken from the beaker with dabbing off surface saturated water, and they were quickly re-weighed in air to produce the saturated wet weight (W3). The porosity of the scaffolds (n = 5) was calculated via the following equation: porosity (%) = (W3 − W1)/(W3 − W2) × 100%.
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.
