The ( Delta G ) values indicate the spontaneous nature of absorption of SO2 into chloride solution.
Electrostatic attraction, covalent binding, and hydrophobic absorption are spontaneous processes to assemble and disassemble the molecules of gold nanoparticles (GNP).
The interaction of light with matter may be characterized in a number of ways, such as transmission, absorption, reflection, spontaneous emission and scattering.
Einstein mathematically expressed the statistical nature of the three possible radiative transition routes (spontaneous emission, stimulated emission, and absorption) with the so-called Einstein coefficients and quantified the relations between the three processes.
Our aim was to measure the fat content in pericardial suction blood and to determine how it can be reduced by simple spontaneous density separation and surface absorption.
The non-intrusive techniques of planar laser-induced fluorescence, ultraviolet-visible absorption spectroscopy and spontaneous laser Raman spectroscopy were used to map out species and temperature profiles above the surface of self-deflagrating RDX/GAP/BTTN model propellant with a pseudo pre-mixed flame.
The nonintrusive techniques of planar laser-induced fluorescence, ultraviolet/visible absorption spectroscopy, and spontaneous laser Raman spectroscopy were used to map out species and temperature profiles above the surface of self-deflagrating cyclotetramethylene tetranitramine (HMX /glycidyl azide polymer (GAP)/butanetriol trinitrate (BTTN) model propellant with a pseudo premixed flame.
In this case, the rate 1/τs is the sum of phonon-assisted absorption and emission (spontaneous plus stimulated) rates between the lowest bright and dark states, while the dephasing is given only by the relaxation (hence emission) rate.
Spontaneous activation of rhodopsin without light absorption occurs at a much lower rate in rod photoreceptors and insect rhabdoms than in cones.
The absorption, photoluminescence, and amplified spontaneous emission (ASE) spectra of BBQ are displayed in Figure S1 in the Supporting Information.
