Implant Surface Characterization by Electron Microscopy

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

The study of the morphology and elemental composition of the implant surfaces depending on the cleaning method compared to the control implants was performed by electron microscopic methods. Electron microscopy studies were carried out in the laboratory of electron microscopy of the Center for Collective Use of the Siberian Federal University on a scanning electron microscope (SEM) JEOL JSM 7001F (JEOL Ltd., Akishima, Japan). The surface morphology was studied in the secondary electron mode (sei) at ×1500 and ×5000 magnifications.
The JEOL JSM 7001F is equipped with an INCAPentaFETx3 energy-dispersive spectrometer (Oxford Instruments, Oxford, UK), which allows for analyzing chemical elements from B (boron) to U (uranium). The X-ray spectral microanalysis (EDX) method with a high degree of locality makes it possible to determine the elemental composition of an object. Before studying the elemental composition of the samples, the spectrometer was calibrated against Co at an operating accelerating voltage of 15 kV. X-ray spectral microanalysis was carried out at an accelerating voltage of 15 kV, a beam current of 7 × 10⁻⁹ A, and a working distance of 10 mm.

Surface Characterization of TiO2 by SEM, EDX, and XPS

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

In order to examine the difference in the surface structure, surface analysis was carried out by scanning electron microscopy (SEM, JSM‐7001F, JEOL Ltd, Japan), energy dispersive X‐ray (EDX, JSM‐7001F, JEOL Ltd, Japan), and X‐ray photoelectron spectroscopy (XPS, ESCALAB 220i‐XL, VG Scientific Instruments). In addition, the surface hydrophilicity of TiO₂ was studied by measuring the static contact angle with a sessile drop of distilled water deposited on the sample surface.³⁵ The volume of the liquid was kept constant (10 μl), and each contact angle value was the average of five measurements at room temperature.

Characterizing Chelyabinsk Meteorite Melt Veins

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

We selected several fragments of Chelyabinsk meteorite containing shock-melt veins. They were embedded in epoxy and cut at the center. The cut surface was polished with diamond abrasive and isopropyl alcohol. The polished samples were carbon-coated and observed with scanning electron microscopes (Hitachi S-3400N and JEOL JSM-7001F). Accelerating voltage and probe current were 15 kV and 1.4 nA, respectively. Chemical compositions of the constituent phases were determined with an energy-dispersive X-ray spectrometer attached to the SEM, JEOL JSM-7001F. Phase identification of materials was conducted with a micro-Raman spectrometer (JASCO NRS-5100). Wavelength and power of the laser were 532 nm and 6.5 mW, respectively. The laser beam was focused to ~1 μm in diameter on the sample through an attached ×100 objective lens. Raman signals from the sample were collected for 60–240 seconds and accumulated twice for each spectrum. Raman shift was calibrated with the strong peak of silicon standard at 520 ± 0.5 cm⁻¹.

The spheres were sonicated for 5 min in an ultrasonic water bath, and 3 μL of the sphere suspension was placed on a cover glass to dry. The samples were subsequently sputtered with an Au layer using a Quorum Sputter Coater Q150T ES (Quorum Technologies, Ringmer, UK), and then, the samples were analyzed under a JEOL JSM-7001F (JEOL. Ltd, Tokyo, Japan) field emission scanning electron microscope at a 15 kV accelerating voltage. Energy-dispersive X-ray spectroscopy was performed using an X-Max silicon drift detector (Oxford Instruments, Abingdon, UK) and analyzed using INCA Energy software (Oxford Instruments Analytical, High Wycombe, UK).
At least 70 individual spheres were measured on several randomly selected SEM images to calculate an average particle size. The particle sizes were determined with ImageJ 1.46r software by measuring the diameter of separated particles. The values represent the mean from three independent experiments.

The fabricated films were subsequently imaged by scanning electron microscope (SEM) JEOL JSM-7001F (JEOL Ltd., Tokyo, Japan). The thickness of the films and their roughness were measured by an atomic force (AFM) neaSNOM Microscope (neaspec GmbH, Munich, Germany).

The morphology of the developed coatings was evaluated using a scanning electron microscope JEOL-JSM7001F, at an operating voltage of 20 kV. The chemical composition of the coatings was determined using an X-ray energy dispersive spectrometer (EDS) analysis. The particle size of the F 0.1 coating was studied using a Transmission Electron Microscope (TEM) (Hitachi H-8100-NA with an acceleration voltage of 200 kV). Before imaging, F 0.1 coating particles were detached from the titanium substrate and dispersed in ethanol. Then, the suspension particles were placed on the carbon-coated copper grid and dried at room temperature. Attenuated total reflectance (FTIR-ATR) spectroscopy using a Nicolet (Thermo Electron) was used to characterize the functional groups and chemical composition of the HA, F 0.01, and F 0.1 coating over a range of 650–4000 cm⁻¹ and a resolution of 8 cm⁻¹. X-ray photoelectron spectroscopy (XPS; Kratos Axis Ultra HSA, Aluminum mono, Eo = 15 kV (90 W) 1 eV per step in a 300 μm × 700 μm area) was used for fluorine, calcium, and phosphorus content analysis at the surface of the F 0.1 coating.

Surface Wettability and AgNPs Characterization

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

Surface wettability was assessed by the sessile drop method in a goniometer (OCA 15, Dataphysics instrument, Filderstadt, Germany), where a 3.0 µL MilliQ water drop was deposited at 1 µL/s on the surface of each sample. Three drops per sample and three samples per condition were tested.
The presence of AgNPs on the Ti-AgNPs and Ti-Ag/PLATF samples was evaluated with a SEM coupled with an EDS detector (JEOL JSM-7001F, Jeol Ltd., Japan). SEM images were analyzed to determine the average size of the AgNPs deposited through ImageJ software (1.53q, NIH, Bethesda, MD, USA) by binarization and the posterior automatic quantification of quasi-spherical particles.
The surface chemical composition of all samples was evaluated with XPS, acquired with a non-monochromatic Mg anode X50 source, operating at 150 W, and a Phoibos 150 MCD-9 detector (D8 advance, SPECS Surface Nano Analysis GmbH, Berlin, Germany). Casa XPS software (Version 2.3.16) was used to analyze the spectra. Peaks were fitted in relation to the C1s signal at 284.8 eV. Two samples per condition were evaluated.

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.
