For the electrochemical impedance measurement, Pt (Sino-Platinum Metals Co., Ltd) was used as the counter and reference electrode prepared by baking screen-printed Pt paste on the other side of the BZCYYb substrate (symmetrically opposite to the prepared anode) in air at 750°C for 0.5 h. The gap between the round-shaped counter and ring-shaped reference electrode was 4.8 mm. Pt mesh and wire were used as the current collector and measuring lead. The anode was sealed onto the cell holder (Al2O3 tube) by a Ceramabond® glass sealant (Aremco Product, Inc.). Wet (3 mol.% H2O) H2 or CH4 was fed to the anodes at a constant flow rate of 100 ml min−1; and ambient air was supplied to the cathode at 250 ml min−1. Electrochemical impedance spectra (EIS) were obtained at open circuit with voltage amplitude of 20 mV in the frequency range from 106 to 10−1 Hz by using an impedance/gain phase analyzer (Solartron 1260) and an electrochemical interface (Solartron 1287). The full cell test was conducted at 200 mA cm−2. The anodes exposed to wet and dry CH4 for various time at 750°C were subjected to SEM examination and Ramann spectroscopy (RS, LabRAM HR800, Horiba JobinYvon) for carbon detection.

The scaffolds were coated with platinum before observation. The microstructure of scaffolds was then observed by a field emission scanning electron microscope (FESEM, Nova NanoSEM, Netherlands) at an accelerating voltage of 10 kV. The diameter of nanofibers was calculated using representative images in OriginPro 9 Software.
Surface characteristics of the scaffolds were recorded using an FTIR spectrometer (Thermo Scientific, Nicolet iS50R, Waltham, America) and a Raman spectrometer (LabRAM, HR800, Horiba JobinYvon, France). FTIR was measured at a resolution of 4 cm−1 in the frequency range of 400–5000 cm−1, while the Raman spectra analysis was performed using a scanning range of 100–4000 cm−1. The excitation source was a 30 mW diode laser with a 532 nm wavelength. The X-ray diffraction (XRD) analysis was determined using an X-ray diffractometer (XRD, Empyrean, Netherlands) with Cu-Kα radiation in the range of 5°–90° (2θ).

RM (LabRAM HR 800, Horiba Jobin Yvon, Villeneuve d'Ascq, France) was used in wet conditions on the radial plane. This technique uses Raman inelastic scattering to obtain information on the chemical composition of the material 27 . A 532-nm laser was used to excite the electrons within the material. The 40X immersion objective (LUMPLFLN 40XW, Olympus) and numerical aperture (NA) of 0.8 produced a laser spot approximately 0.8 mm in diameter.
The acquisitions were made on the spectral range of 350 cm À1 e 1750 cm À1 , with an integration time of 30 s and one accumulation. Three spectra were acquired for each point, and six points were analyzed in all samples. The spectra were de-spiked, and the background was subtracted using a user-defined baseline correction routine in Matlab (The MathWorks Inc., Natick, Massachusetts, USA). Next, three spectra per point were averaged, and the resulting spectrum was smoothed using a sliding average over seven points algorithm in a Matlab routine. Finally, spectra were normalized to the phenylalanine ring breathing band intensity at 1004 cm À1 , which is distinct and constant between samples 28 .

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.
