Scattering properties light objects

It is well known that a light beam carries momentum and tliat tire scattering of light by an object produces a force. This property of light was first demonstrated by Frisch [K)] tlirough tire observation of a very small transverse... 

Nanoscale objects have unique properties part way between the quantum and macroscopic worlds that result in unexpected properties such as light scattering. 

Where applicable, the use of competitive cations for the control of anionic depressors appears to represent the method of choice. No spectral interference arises in atomic absorption from the addition of another cation, an objection often raised in emission. The concentrations of the added salt required for full anion control usually are less than 1%, a salt level well below that at which light scattering is observed. When working with serum, denaturation or precipitation of proteins may occur from the addition of high concentrations of lanthanum chloride or other salts, and the concomitant changes in solution properties should be taken into...
