Rotating cell‑based ligand binding assay using radioactivity or fluorescence, is a recent method that measures molecular interactions in living cells in real-time. This method allows the characterization of the binding mechanism, as well as K d, k on and k off. This principle is being applied in several studies, mainly with protein ligands ...
The characterization of mechanical properties in polymers typically refers to a measure of the strength, elasticity, viscoelasticity, and anisotropy of a polymeric material. The mechanical properties of a polymer are strongly dependent upon the Van der Waals interactions of the polymer chains, and the ability of the chains to elongate and align ...
In addition, field-portable direct reading instruments can be used for continuous recording of normal fluctuations in particle count, size distribution, and mass. By documenting the workers' activities, data-logged results can then be used to identify workplace tasks or practices that contribute to any increase or spikes in the counts.
In narratology, focalisation is the perspective through which a narrative is presented. [1] Coined by French narrative theorist Gérard Genette, his definition distinguishes between internal focalisation (first-person) and external focalisation (third-person, fixed on the actions of and environments around a character), with zero focalisation representing an omnisicent narrator.

A mass spectrometer used for high throughput protein analysis. Protein mass spectrometry refers to the application of mass spectrometry to the study of proteins.Mass spectrometry is an important method for the accurate mass determination and characterization of proteins, and a variety of methods and instrumentations have been developed for its many uses.
Energy-dispersive X-ray spectroscopy (EDS, EDX, EDXS or XEDS), sometimes called energy dispersive X-ray analysis (EDXA or EDAX) or energy dispersive X-ray microanalysis (EDXMA), is an analytical technique used for the elemental analysis or chemical characterization of a sample. It relies on an interaction of some source of X-ray excitation and ...

Raman spectroscopy is used in chemistry to identify molecules and study chemical bonding and intramolecular bonds. Because vibrational frequencies are specific to a molecule's chemical bonds and symmetry (the fingerprint region of organic molecules is in the wavenumber range 500–1,500 cm −1), [20] Raman provides a fingerprint to identify ...
