Specific heat measurements were performed on samples of about 11 mg at 0 and 16 T in a 16 T Quantum Design physical property measurement system (PPMS) and analysed with Wang’s model39 (link) with n = 4.5. This is a phenomenological model with the limitations discussed in Refs.37 (link),39 (link). The superconducting transitions were evaluated by magnetic measurements in a Quantum Design SQUID magnetometer MPMS XL5. The Hc2 slope was estimated by the peak positions of the Tc-distributions, Tc,peak, at 0 and 16 T in order to calculate . The temperature dependence of the magnetization was measured after zero-field cooling with an applied field of 2 mT. Hysteresis loops were performed at 4.2 K in a Oxford Instruments 14 T Vibrating Sample Magnetometer (VSM) on samples with 3 × 1 × 0.3 mm3 size and the magnetization Jc was calculated using the Bean model53 (link),54 (link).

The SQUID magnetometer MPMS XL5 is a highly sensitive instrument used to measure the magnetic properties of materials. It utilizes a Superconducting Quantum Interference Device (SQUID) to detect and measure extremely small magnetic fields. The MPMS XL5 is capable of measuring a wide range of magnetic moments, from diamagnetic to ferromagnetic materials, over a wide temperature range. It is designed to provide accurate and reliable data for research and development applications.

Magnetization curves were measured using a Quantum Design SQUID magnetometer (MPMS-XL5) from −50 to 50 kOe at 1.9 K. The samples were held in a gelatin capsule. The iron oxide nanoparticles supported on GNP were fixed in a small amount of n-eicosane due to the high magnetic field during the measurements. The temperature was increased at 320 K to melt the n-eicosane. The magnetic responses were corrected with diamagnetic blank data for the sample holder, such as the gelatin capsule, GNP, and n-eicosane. The essential data were subtracted from the diamagnetic blank, which is the net weight of GNP from the ICP-AES analysis results.

Transmission electron microscope JEM 2010 (JEOL, Japan), X-ray photoelectron spectrometer Thermo K-Alpha-Scientific (Waltham, MA, USA), D8 Advance X-ray diffractometer (Bruker, Germany), and SQUID magnetometer MPMS-XL-5 (Quantum Design, CA, USA) were used for nanocomposite characterization (i.e., GO/Fe O ).
In the MSPE procedure, a Ni-coated neodymium magnet, N45 grade, dimensions 45!×!30 mm from Supermagnete (Gottmadingen, Germany) was used as magnetic external field.
The chromatographic analyses were performed by Shimadzu LC-20AT liquid chromatograph (Kyoto, Japan) coupled to a Shimadzu SPD-10A UV-Vis detector (operated at 254 nm), equipped with a Phenomenex C18 column (3 µm particle diameter, 4.6 mm i.d.!×!15 cm) (Torrance, CA, USA). Isocratic water/methanol mixture (50:50, v/v) was employed as mobile phase at a flow rate of 1 mL min . The injection volume was 20 µL.

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.
