Inspect f sem

Manufactured by Thermo Fisher Scientific
Sourced in United States

The Inspect F SEM is a scanning electron microscope (SEM) designed for high-resolution imaging and analysis of surface structures and compositions. It provides detailed information about the morphology and elemental composition of samples at the nanoscale level. The core function of the Inspect F SEM is to enable users to perform advanced materials characterization and analysis in a wide range of applications.

Fiber Morphology and Composition Analysis

Fibre morphology was characterised using SEM and IMAGE J software (National Institutes of Health, Bethesda, MD, USA). The fibres were sputter-coated with gold (Q150R ES, Quorum Technologies, Lewes, UK) for 180 s prior to being imaged by SEM (JEOL JSM-6301F or FEI Inspect-F SEM). Average fibre diameter was calculated by measuring the width of 100 fibres inn IMAGE J.
Chemical composition of the fibres was assessed using energy-dispersive X-ray spectroscopy (EDX) and performed using INCA X-Sight (Oxford Instruments, Abingdon, UK). The voltage used was 20 kV and the working distance was 10 mm. INCA software (ETAS, Derby, UK) was used to analyse the EDX spectra.

Scanning electron microscopy (SEM) images were recorded, using a secondary electron (SE) and back-scattered electron (BSE) detectors, on an FEI Inspect F SEM (Hillsboro, Oregon, USA) in the NanoVision Centre, Queen Mary University of London. An X-Act Oxford Instruments EDX detector was used for EDX measurements (20 kV accelerating voltage) (Abington, Oxfordshire, UK). The samples were coated with carbon for EDX studies and 20 nm of gold for morphological examination.

Comprehensive Material Characterization Protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols
The crystal
structure analysis of all prepared samples was conducted using powder
X-ray diffraction (XRD) with Cu Kα (λ = 1.5406 Å)
radiation in the 2θ range from 10 to 80°. This characterization
was carried out by using a Rigaku XRD instrument from Japan. Furthermore,
the morphology of all of the samples was assessed using a field emission
scanning electron microscope (FE-SEM, FEI Inspect-F SEM). To determine
the content of transition-metal species within all samples after cycling,
X-ray photoelectron spectroscopy (XPS) was employed. This analysis
utilized Al Kα radiation and was performed by using the ULVAC-PHI
(Quantes) instrument. Data were collected and averaged from ten individual
cells. Microstructure analysis was conducted by using a high-resolution
transmission electron microscope (TEM, JEOL JEM-2100F). To safeguard
the integrity of the TiO2/Al2O3 coating
during sample preparation and subsequent processing, a protective
layer of platinum was applied. This protective layer was created through
an initial electron-beam deposition followed by ion-beam-assisted
deposition, employing an SEIKO SMI3050SE Dual-Beam Focused Ion Beam
(FIB) instrument. Following the application of a protective layer,
TEM specimens were carefully prepared using gallium-focused ion-beam
milling techniques.

Scanning Electron Microscopy of Creep Fracture

Check if the same lab product or an alternative is used in the 5 most similar protocols
A FEI Inspect F SEM was utilized to image and record digitally planar sections as well as creep fracture surfaces. The accelerating voltage was 10 or 20 keV. Backscatter electron (BSE) imaging modes were used in the inspection investigations. A minimum of 20 images were taken over an area of 0.1 mm × 0.12 mm with 0% overlap between images. Specimens were sent to a third party for planar surface polishing and etching.

SEM Analysis of Demineralized Dentin Collagen

Check if the same lab product or an alternative is used in the 5 most similar protocols
SEM was employed to observe the collagen structure in each of the seven demineralised dentine models and control (n=3 per group). Preparation involved staining the specimens with 0.1 % osmium tetroxide (Sigma Aldrich, Poole, UK) for 1 hour prior to dehydrating as per EDS samples. Specimens were gently air dried in a fume cupboard over a 12-hour period. The blocks were attached to aluminium pin stubs using carbon sticky tabs, coated with silver dag (Agar Scientific, Essex, UK) and then gold spluttered using an EM SCOPE 500 (Quorum Technologies, Sussex, UK). Specimens were analysed using an Inspect F SEM (FEI™, Oregon, USA).
Four areas of each specimen were viewed at a range of magnifications between x1000 and x80000 viewing both the intra-and inter-tubular dentine. When measuring collagen fibre dimensions measurements were taken from 5 areas on 3 high magnification (80000x) images. Measurements were taken with ImageJ software version 1.46 (Open access, NIH, USA).

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.
