S
Auger electron spectroscopy (AES or simply Auger) is a surface analysis technique that uses an electron beam to excite electrons on atoms in the particle. Atoms that are excited by the electron beam can emit “Auger” electrons. AES measures the kinetic energies of the emitted electrons. The energy of the emitted electrons is characteristic of elements present at the surface and near the surface of a sample. (en) +
M
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. (en) +
S
Scanning Kelvin probe (SKP) and scanning Kelvin probe force microscopy (SKPFM) are probe techniques which permit mapping of topography and Volta potential distribution on electrode surfaces. It measures the surface electrical potential of a sample without requiring an actual physical contact. (en) +
Scanning probe microscopy (SPM) is a branch of microscopy that forms images of surfaces using a physical probe that scans the specimen. (en) +
Scanning Tunneling Microscopy, or STM, is an imaging technique used to obtain ultra-high resolution images at the atomic scale, without using light or electron beams. (en) +
Data resulting from the application of post-processing or model generation to other data. (en) +
C
The instrument used for characterising a material, which usually has a probe and a detector as parts. (en) +
S
Secondary-ion mass spectrometry (SIMS) is a technique used to analyze the composition of solid surfaces and thin films by sputtering the surface of the specimen with a focused primary ion beam and collecting and analyzing ejected secondary ions. (en) +
M
Mechanical testing covers a wide range of tests, which can be divided broadly into two types: 1. those that aim to determine a material's mechanical properties, independent of geometry; 2. those that determine the response of a structure to a given action, e.g. testing of composite beams, aircraft structures to destruction, etc. (en) +
S
Voltammetry in which a square-wave potential waveform is superimposed on an underlying linearly varying potential ramp or staircase ramp. Most instruments show plots of the current at the end of the forward-going pulse and of the backward-going pulse vs. the potential, as well as their difference. This can give valuable information on the kinetics of the electrode reaction and the electrode process. The current is sampled just before the end of the forward- going pulse and of the backward-going pulse and the difference of the two sampled currents is plotted versus the applied potential of the potential or staircase ramp. The square-wave voltammogram is peak-shaped. The sensitivity of SWV depends on the reversibility of the electrode reaction of the analyte. (en) +
Chronopotentiometry where the applied current is changed in steps. (en) +
T
Tensile testing, also known as tension testing, is a test in which a sample is subjected to a controlled tension until failure. Properties that are directly measured via a tensile test are ultimate tensile strength, breaking strength, maximum elongation and reduction in area. From these measurements the following properties can also be determined: Young's modulus, Poisson's ratio, yield strength, and strain-hardening characteristics. Uniaxial tensile testing is the most commonly used for obtaining the mechanical characteristics of isotropic materials. Some materials use biaxial tensile testing. The main difference between these testing machines being how load is applied on the materials. (en) +
Thermogravimetric analysis or thermal gravimetric analysis (TGA) is a method of thermal analysis in which the mass of a sample is measured over time as the temperature changes. This measurement provides information about physical phenomena, such as phase transitions, absorption, adsorption and desorption; as well as chemical phenomena including chemisorptions, thermal decomposition, and solid-gas reactions (e.g., oxidation or reduction). (en) +
Method of mechanical testing that provides values for the modulus of elasticity in bending, flexural stress, flexural strain, and the flexural stress–strain response of a material sample. (en) +
Transmission electron microscopy (TEM) is a microscopy technique in which a beam of electrons is transmitted through a specimen to form an image. The specimen is most often an ultrathin section less than 100 nm thick or a suspension on a grid. An image is formed from the interaction of the electrons with the sample as the beam is transmitted through the specimen. The image is then magnified and focused onto an imaging device, such as a fluorescent screen, a layer of photographic film, or a sensor such as a scintillator attached to a charge-coupled device.

U
Ultrasonic testing (UT) is a family of non-destructive testing techniques based on the propagation of ultrasonic waves in the object or material tested. In most common UT applications, very short ultrasonic pulse-waves with center frequencies ranging from 0.1-15 MHz, and occasionally up to 50 MHz, are transmitted into materials to detect internal flaws or to characterize materials. A common example is ultrasonic thickness measurement, which tests the thickness of the test object, for example, to monitor pipework corrosion. Ultrasonic testing is often performed on steel and other metals and alloys, though it can also be used on concrete, wood and composites, albeit with less resolution. It is used in many industries including steel and aluminium construction, metallurgy, manufacturing, aerospace, automotive and other transportation sectors. (en) +
Ultraviolet–visible spectroscopy or UV/VIS refers to absorption spectroscopy or reflectance spectroscopy in the ultraviolet-visible spectral region. (en) +

V
Vapor pressure osmometry measures vapor pressure indirectly by measuring the change in temperature of a polymer solution on dilution by solvent vapor and is generally useful for polymers with Mn below 10,000–40,000 g/mol. When molecular weight is more than that limit, the quantity being measured becomes very small to detect. (en) +
Viscometry or viscosity method was one of the first methods used for determining the MW of polymers. In this method, the viscosity of polymer solution is measured, and the simplest method used is capillary viscometry by using the Ubbelohde U-tube viscometer. In this method, both the flow time of the polymer solution (t) and the flow time of the pure solvent (t0) are recorded. The ratio of the polymer solution flow time (t) to the flow time of pure solvent (t0) is equal to the ratio of their viscosities (η/η0) only if they have the same densities. (en) +
