Cross-section of the membrane was imaged using transmission electron microscopy (TEM, Talos F200X) coupled with energy dispersive spectroscopy (EDS, Oxford Instrument X-MaxN 80 detector). A TEM sample of the nanocomposite rGO layer cross-section was prepared using a focused ion beam (Helios FEI). X-ray photoelectron microscopy (XPS, Thermo Scientific K-Alpha) was used to determine the elemental composition across the membrane depth. The crystal structure and the specific surface area of the Fe-based nanoparticles synthesized in the solution phase were determined using X-Ray Diffraction (XRD, Siemens D500, Cu Kα 1.5418 Å) and a Brunauer–Emmett–Teller (BET, Micromeritics TriStar 300) analyzer. Functional groups of rGO were characterized by Fourier Transform Infrared Spectroscopy (FTIR, Varian 7000e). Contact angles were measured using a Drop shape analyzer (DSA 100 Kruss), and C 1s binding energy spectra were obtained using XPS.

Nanoscale Analysis of Fe/Pd Nanoparticles in Membranes

Check if the same lab product or an alternative is used in the 5 most similar protocols
The size and distribution of the Fe/Pd nanoparticles were studied both on the surface and inside the membrane pores after preparation of a lamella using FIB-SEM (FEI Helios Nanolab 660) analysis. Following surface imaging of the region of interest, a lamella was lifted out of the membrane sample and its thickness gradually reduced using FIB until it was transparent. The specimen was then imaged via scanning transmission electron microscopy (STEM) in the FIB-SEM. Following this treatment, the Fe/Pd nanoparticles inside the membrane pores could then be directly observed in transmission.
The elemental composition of the particles was determined by energy dispersive X-ray spectroscopy (EDX, Oxford Instruments X-MaxN 80 detector) on the lamella. Their reduced thickness decreased scattering of the beam and optimized EDX lateral resolution. Although individual nanoparticles could not be distinguished during EDX elemental mapping, regions where particles agglomerated were identified. Elemental composition of this agglomerate was possible, and only Fe and Pd were considered during this analysis. Other observed elements such as the C, H, F, O (membrane elements), Pt (coating), Ga (beam) and Cu (holder) were ignored to clearly analyze Fe and Pd composition.

The MnO2 nanorods and rGO/MnO2 nano-heterostructure were characterized by various complementary experimental methods. The XRD patterns were obtained with a Bruker D8 Advance X-ray diffractometer using the Cu Kα line (λ = 1.54 Å) at 1° grazing angle. The HR-TEM micrographs and selected area electron diffraction (SAED) patterns were obtained with JEOL-JEM 2100 microscope operating at 200 kV. The samples were dry dispersed over 300 mesh copper grids coated with holey carbon film. A Field Emission Scanning Electron Microscope (FEG-SEM Model – Tescan MAIA3) was used to examine the morphology and surface topography of the MnO2 nanorods and rGOs/MnO2 composite. The accelerating voltage was 15 kV. X-ray spectroscopy (EDS) measurements were done using Oxford Instruments X-MaxN 80 detector and analyzed using Aztec software.

Membrane Cross-Section Analysis by FIB-SEM

Check if the same lab product or an alternative is used in the 5 most similar protocols
Particle size and distribution were determined across the entire depth of membranes by directly imaging the cross-section plane of the membrane in the SEM. To maintain the structures of particles and membrane pores, an advanced cross-sectioning method using focused ion beam (FIB, FEI Helios Nanolab 660) was developed. A cross-sectional plane was first created by fracturing a small piece of the membrane following immersion in liquid nitrogen. The FIB was then performed to expose an undamaged region of the membrane. For gallium ion-based FIB systems, typical cross-sectioning processes only expose the first few tens of micrometers below the surface [52 ,59 ]. The advanced FIB preparation method allows exposure of the entire membrane cross-section (170 μm), creating a flat and smooth surface suitable for SEM imaging and elemental analysis using energy dispersive x-ray spectroscopy (EDS, Oxford Instruments X-MaxN 80 detector). The details of FIB preparation are described in SI section 3. Particle composition was also analyzed using X-ray diffractometer (Siemens D500, Cu Kα 1.5418 Å).

After PFOA adsorption, PNIPAm hydrogel samples were dried and analyzed using energy dispersive X-ray spectroscopy (EDS, Oxford Instruments X-MaxN 80 detector). Hydrogel samples were freeze dried and mounted on the holder inside the scanning electron microscope chamber (FEI Helios Nanolab 660) and EDS analysis was performed in order to find the relative ratios of carbon, nitrogen, oxygen, and fluorine. Using the atomic ratios of fluorine, which only exists in PFOA, versus nitrogen, which only exists in PNIPAm, the adsorbed amount can be loosely predicted and compared to the equilibrium adsorption data.

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.
