Molecular Basis of Stationary Phase Survival and Applications
Frontiers in Microbiology, 2017 Stationary phase is the stage when growth ceases but cells remain metabolically active. Several physical and molecular changes take place during this stage that makes them interesting to explore.

Stationary phases based on the nanoparticles for pharmaceutical and biomolecule separations [PDF]
Nanochemistry Research, 2021 Because of impossibility to achieve a general column for separation purposes, columns must be amended in order to acquire specific chemical characteristics such as hydrophobic, hydrophilic or ionic interactions.

The Stationary Phase Approximation, Time-Frequency Decomposition and Auditory Processing [PDF]
, 2012 The principle of stationary phase (PSP) is re-examined in the context of linear time-frequency (TF) decomposition using Gaussian, gammatone and gammachirp filters at uniform, logarithmic and cochlear spacings in frequency. This necessitates consideration

Gravitational waves from inspiraling compact binaries: Validity of the stationary-phase approximation to the Fourier transform [PDF]
, 1999 We prove that the oft-used stationary-phase method gives a very accurate expression for the Fourier transform of the gravitational-wave signal produced by an inspiraling compact binary. We give three arguments.

Solvent Influence on Zeta Potential of Stationary Phase—Mobile Phase Interface
Molecules, 2022 Zeta potential is a surface characteristic formed on the solid surface and liquid interface. It is an interesting way to describe the surface properties of materials; thus, a series of four homemade polar embedded stationary phases that contain phosphate

Countercurrent chromatography in analytical chemistry (IUPAC technical report) [PDF]
, 2009 © 2009 IUPACCountercurrent chromatography (CCC) is a generic term covering all forms of liquid-liquid chromatography that use a support-free liquid stationary phase held in place by a simple centrifugal or complex centrifugal force field. Biphasic liquid

The use of the stationary phase method as a mathematical tool to determine the path of optical beams [PDF]
, 2015 We use the stationary phase method to determine the path of optical beams which propagate through a dielectric block. In the presence of partial internal reflection, we recover the geometrical result obtained by using the Snell law.
