13C NMR 13C NMR spectra were measured on a Bruker 400 MHz FT-NMR spectrometer operating at 100 MHz in polymer solutions (less than 20 wt%) with o- dichlorobenzene as solvent at 110◦C, with the high- est single peak as the reference (132.9 ppm). Consid- ering that T1 of methylene...
The average tensile strength of SS 321at 900°C was 108±6MPa, and the WAAM 321 samples showed higher strength (135±7MPa). The decrease in tensile strength is attributed to the activation of a multi-slip system, resulting in a lower resistance to dislocation motion at elevated temperatures....
FT-IR spectrum of amino-MNPs. 3.3. Magnetic Properties Magnetization curves of amino-MNPs at room temperature are shown in Figure 4. The curves indicated that the MNPs were ferromagnetism and very close to complete superparamagnetism with a saturation magnetization (Ms) of about 48 emu/g, rem...
In the TPPy-GC/FT IR measurement, HP 6890 GC was used instead of HP 5890. After finishing the TPPy procedure, the column temperature was quickly raised to 50 C and then heated up to 300 C at a rate of 5 C/min and held for 10 min. The other conditions were basically the ...
