Microscopy is a category of characterization techniques which probe and map the surface and sub-surface structure of a material. These techniques can use photons, electrons, ions or physical cantilever probes to gather data about a sample's structure on a range of length scales. Some common examples of microscopy techniques include: Optical ...
X-ray microscopy is three-dimensional and non-destructive, allowing for repeated imaging of the same sample for in situ or 4D studies, and providing the ability to "see inside" the sample being studied before sacrificing it to higher resolution techniques. A 3D X-ray microscope uses the technique of computed tomography , rotating the sample 360 ...
PEEM – Photoemission electron microscopy (or photoelectron emission microscopy) PES – Photoelectron spectroscopy; PINEM – photon-induced near-field electron microscopy; PIGE – Particle (or proton) induced gamma-ray spectroscopy, see nuclear reaction analysis; PIXE – Particle (or proton) induced X-ray spectroscopy; PL – Photoluminescence
The dispersion staining is an analytical technique used in light microscopy that takes advantage of the differences in the dispersion curve of the refractive index of an unknown material relative to a standard material with a known dispersion curve to identify or characterize that unknown material. These differences become manifest as a color ...
Hyphenated techniques are widely used in chemistry and biochemistry. A slash is sometimes used instead of hyphen, especially if the name of one of the methods contains a hyphen itself. Examples of hyphenated techniques: Gas chromatography-mass spectrometry (GC-MS) Liquid chromatography–mass spectrometry (LC-MS)
Pump–probe microscopy is a non-linear optical imaging modality used in femtochemistry to study chemical reactions. It generates high-contrast images from endogenous non-fluorescent targets. It generates high-contrast images from endogenous non-fluorescent targets.
Choice chemistry is typically gold-coated tip and surface with R−SH thiols attached, R being the functional groups of interest. CFM enables the ability to determine the chemical nature of surfaces, irrespective of their specific morphology, and facilitates studies of basic chemical bonding enthalpy and surface energy .
High-resolution transmission electron microscopy is an imaging mode of specialized transmission electron microscopes that allows for direct imaging of the atomic structure of samples. [ 1 ] [ 2 ] It is a powerful tool to study properties of materials on the atomic scale, such as semiconductors, metals, nanoparticles and sp 2 -bonded carbon (e.g ...
