Octominin-CNPs Morphological Characterization

Check if the same lab product or an alternative is used in the 5 most similar protocols

Morphological characterization of the Octominin-CNPs or CNPs was performed by TEM analysis. Briefly, samples were dissolved in PBS and 10 µL of the sample was placed on formvar/carbon-coated copper grid and incubated for 10 min. The excess sample amount was removed using filter paper. Then, 5 µL of 2% uranyl acetate (Sigma-Aldrich, St. Louis, MO, USA) was placed on the grid for 5 s, and the excess amount of uranyl acetate was removed by aspiration using filter paper. The dried grid was observed using a 300 keV Field emission–TEM (TecnaiTM G2 F30 super-twin (FEI), Hillsboro, OR, USA).

The current–voltage (I–V) characteristics were recorded using an Iviumsoft apparatus with simulated AM 1.5 illumination (100 mW cm⁻²) via a solar simulator (Abet Technologies Sun 3000) in normal air conditions. The thicknesses of the coated films were measured using a thickness profile metre (Surfcorder ET 3000, Kosaka Laboratory, Ltd.). Cross-sectional TEM samples of the printed OSC module were prepared using a dual beam-focused ion beam (Helios NanoLabTM). The TEM images were obtained using field emission TEM (FEI TecnaiTM G2 F30 Super-Twin) operated at 200 kV. The topographies of surface images were characterized using atomic force spectroscopy.

The purified GST-fusion C-RBD or N-RRM domain of the HNRNPG protein was diluted to 5 μM in 10 mM Tris-Cl (pH 7.4), 100 mM KCl, 2.5 mM MgCl₂. The 5 μl sample solution was spotted on a 400 mesh carbon grid, washed with 1–2 drops of water, stained with 2 drops of 1% uranyl acetate, blotted and dried in air. Images were obtained at 68.6K× magnification on an FEI Tecnai G2 F30 Super Twin scanning transmission electron microscope.

The nanowires dispersed in hexane were spread on a copper grid and a silicon wafer for measurement using transmission electron microscopy (TEM) and scanning electron microscopy (SEM), respectively. TEM image and STEM-EDX were taken with a FEI Tecnai G2 F30 Super-Twin transmission electron microscope operating at 300 kV. SEM image and X-ray mapping data were obtained with a JSM-6700F field emission scanning electron microscope at 30 kV operating voltage, equipped with an INCA energy dispersive X-ray spectrometer (EDS). X-ray diffraction (XRD) patterns were taken using a Rigaku Ultima III diffractometer equipped with a rotating anode and Cu K_α radiation source (λ = 0.15418 nm). Electrical characterization of the nanowire devices was performed using a probe station (MSTECH MST-6000C, Korea) and the Keithley SCS-4200 system.

Transmission Electron Microscopy of e-SiNWs and Spheroids

Check if the same lab product or an alternative is used in the 5 most similar protocols

As we have described previously (67 ), e-SiNWs were gently sonicated in isopropyl alcohol and dispersed onto lacey carbon grids (Ted Pella Inc.). Transmission electron microscopy imaging was conducted using a 300-kV FEI Tecnai G2 F30 Super Twin transmission electron microscope. Spheroids were fixed with 2.5% glutaraldehyde, postfixed in PBS-buffered 1% osmium tetroxide with 1.5% K+ ferricyanide, dehydrated in graded ethanol and acetonitrile, and embedded in PolyBed 812 (Polysciences). Seventy-nanometer-thick spheroid sections were prepared using a Leica UltraCut R and a diamond knife, stained with Hanaichi Pb citrate and uranyl acetate, and imagined using a JOEL 200 CX transmission electron microscope.

The X-ray powder diffraction (XRD) patterns were recorded on a Rigaku D/Max 2500 VB2 + /PC X-ray powder diffractometer equipped with Cu Kα radiation (λ = 0.154 nm). Transmission electron microscopy (TEM) images were obtained with a JEOL JEM-1230 transmission electron microscope operating at 100 kV. High-resolution TEM (HRTEM) and energy-dispersive X-ray spectrometry (EDX) elemental mapping were performed using an FEI Tecnai G2 F30 Super-Twin high-resolution transmission electron microscope at an accelerating voltage of 300 kV. The X-ray photoelectron spectra (XPS) were measured using a Thermo Fisher ESCALAB 250Xi XPS system with a monochromatic Al Kα X-ray source. All binding energies were calibrated to the C 1 s peak (284.8 eV). Inductively coupled plasma optical emission spectroscopy (ICP-OES, Optima 7300 DV, Perkin Elmer) was used to determine the metal contents of as-prepared catalysts.

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.
