two-phase technique
1Aqueous two-phase system — Aqueous biphasic systems (ABS) or aqueous two phase systems (ATPS) are clean alternatives for traditional organic water solvent extraction systems. ABS are formed when 2 polymers, one polymer and one kosmotropic salt, or two salts (one chaotropic …

3Phase field models — A phase field model is a mathematical model for solving interfacial problems. It has been mainly applied to solidification dynamics, [ [http://arjournals.annualreviews.org/doi/abs/10.1146/annurev.matsci.32.101901.155803 WJ. Boettinger et al.… …
4Phase contrast microscopy — Phase contrast image of a cheek epithelial cell Phase contrast microscopy is an optical microscopy illumination technique of great importance to biologists in which small (invisible to the human eye) phase shifts in the light passing through a… …
5Phase-Comparison Monopulse — Phase interferometry describes a technique that can be used in radar and direction finding applications to accurately estimate the direction of arrival of a signal from the phase difference of the signal measured on two (or more) separated… …
6Phase dispersion minimization — (PDM) is a data analysis technique that searches for periodic components of a time series data set. It is useful for data sets with gaps, non sinusoidal variations, poor time coverage or other problems that would make Fourier techniques unusable …
7Two-dimensional nuclear magnetic resonance spectroscopy — (2D NMR) is a set of nuclear magnetic resonance spectroscopy (NMR) methods which give data plotted in a space defined by two frequency axes rather than one. Types of 2D NMR include correlation spectroscopy (COSY), J spectroscopy, exchange… …
8Two-photon excitation microscopy — is a fluorescence imaging technique that allows imaging of living tissue up to a very high depth, that is up to about one millimeter. Being a special variant of the multiphoton fluorescence microscope, it uses red shifted excitation light which… …
9Two-photon absorption — (TPA) is the simultaneous absorption of two photons of identical or different frequencies in order to excite a molecule from one state (usually the ground state) to a higher energy electronic state. The energy difference between the involved… …
10Phase offset modulation — works by overlaying two instances of a periodic waveform on top of each other. (For the purposes of softsynths, the waveform is usually generated by using a lookup table.) The two instances of the waveform are kept slightly out of sync with each… …
