Thermogravimetric analysis (TGA ) of the as-prepared N, S co-doped graphene/Fe3O4 nanocomposite was carried out with a TGA/DSC1 type instrument (TGA/DSC1 SF/1382, Mettler Switzerland, German) with a heating rate of 10 °C min−1 from room temperature to 1000 °C in air. The phase of the products was examined with an X’ Pert Pro MPD X-ray diffractometer with Cu Kα radiation (λ = 1.5418 Å, Philips, Holland). The morphology of these nanomaterials was evaluated with S-3000 scanning electron microscope (SEM , S-3000, HITACHI, Japan), NanoSEM 230 field emission scanning electron microscope (FE-SEM , Nova NanoSEM 230, FEI, America) and a Tecnai G2F20 S-TWIN transmission electron microscope (TEM , Tecnai GX F20 S-TWIN, FEI, America). The X-ray photoelectron spectroscopy (XPS ) experiments were carried out on a VG Scientific ESCALAB 250 instrument (XPS , ESCALAB 250, Thermo Scientific, America) by using aluminum Kα X-ray radiation during XPS analysis. The Raman spectra were obtained on a Renishaw Invia Raman microscope excited by an argon ion laser beam (514.5 nm, 20 mW).

The cross sections of polymeric samples were coated with a thin layer of Au-Pd. Imaging was obtained using scanning electron microscopes (Hitachi S3000, Hitachi High-Technologies Co., Tokyo, Japan for non-implant-related applications and Phenom XL, Thermo Fisher Scientific, Waltham, MA, USA for implant-related applications), and the chemical composition was analyzed via energy-dispersive X-ray spectroscopy (Hitachi S3000, Hitachi High-Technologies Co., Tokyo, Japan). Porosity measurements were carried out via image analysis from cross sections using ImageJ (NIH, USA). Flat dog bone specimens were printed under different material conditions, whose dimensions were approximately 30–40 mm long and 8–12 mm wide after sintering. The ultimate tensile strength (UTS) values were measured on a tensile test apparatus (6800 Series, Instron, Norwood, MA, USA) using a crosshead speed of 6–7 mm/min (ASTM E8-03). Three independent trials were conducted under the same conditions.

Model fibrous microplastics were prepared using the method initially developed by M. Cole [43 (link)]. Briefly, three types of textile-relevant fibers, including PES and PAN (Reinhard Strauss GmbH & Co. KG, Viersen, Germany) and PA6 (Heimbach Group GmbH, Düren, Germany), were aligned, embedded in a water-soluble freezing agent (Tissue-Tek® O.C.T. Compound), and sectioned into microfibers with a length of 10 μm. The sectioning was performed using a cryotome (Leica CM1950). The freezing agent was washed off and powders of microfibers were obtained using lyophilization. The resulting particles were imaged via a Hitachi S3000 scanning electron microscope (SEM) and their size distribution was analyzed using ImageJ.

We analyzed grazer mouthpart morphology of fourth instar larvae using scanning electron microscopy (SEM, × 10,000, Hitachi S-3000). For SEM observation, the individual larvae were dehydrated via an ethanol series (30, 50, 70, 90, 95, and 100%), 10 min at each concentration. The dehydrated sample was soaked with 100% isoamyl acetate for 1 h at room temperature, dried with CO2 using a critical point dryer (HPC-2 Critical Point Dryer; Hitachi, Tokyo, Japan), and sputter-coated with gold. The SEM images for periphytic mat on clay tiles were prepared and examined in a similar manner.

The characterization of the synthesized nanoparticles was carried out using different characterization techniques. The crystalline phases of the nanoparticles obtained after calcination were analyzed by X-ray diffraction (XRD), using an X’Pert PRO PANalytical instrument with Cu kα = 1.54056, 20 kV, that scanned from 5° to 80° at 2°/min scanning speed. The functional groups and the vibrational band of bonds were determined by Fourier Transformed Infrared spectroscopy (FTIR) using a Bruker Alpha-Platinum ATR instrument with 40 scans and resolution of 4 cm−1 measured between a wavelength of 4000 to 400 cm−1. Scanning electron microscopy (SEM; HITACHI S-3000) was used to determine the microstructure and morphology of the nanoparticles with an energy-dispersive X-ray spectrometer (EDX) used to analyze the component and sample purity of the nanoparticles. The mean particle size and zeta potential of the nanoparticles were measured using Horiba Scientific, SZ 100 instrument.

The FTIR spectra were
recorded on a Shimadzu IRPrestige 21 spectrometer at rt. The samples
were measured as KBr discs in the range of 4500–500 cm–1. XRD was used to determine the crystallinity of the
electrode materials on an automatic Philips powder diffractometer
with nickel-filtered Cu Kα radiation. The XRD patterns were
recorded from 10° to 80°. The morphology, size, and microstructure
of the products were investigated by SEM (S-3000 and SU-70, Hitachi).
The BET and the Barrett–Joyner–Halenda methods (NOVA
3200e system, Quantachrome Instrument, USA) were employed to investigate
the BET specific surface area and pore size distribution of the samples. 1H (400 MHz) and 13C (100 MHz) NMR spectra were
recorded on a Varian INOVA 400 NMR spectrometer at rt. The chemical
shifts of the protons were relative to tetramethylsilane (Me4Si). The data are presented as follows: chemical shift (ppm), multiplicity
(s = singlet, d = doublet, t = triplet, m = multiplet), and coupling
constant J (Hz). The elemental analysis of the BIMs
was performed with an Elementar Vario EL III element analyzer (Elementar
Analysensysteme GmbH, Germany) for C, H, N, and S determination at
Korea Basic Science Institute (Busan, Korea).

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.
