ThFFF is a method for the particle and macro-molecule separation in electrolyte and non-electrolyte solvents according to their interaction with the solvent molecules or/and ions of the added salt. For particles, these are surface interactions, though the particle/solvent thermal conductivity ratio is also important. Thermophoretic mobility may be cal culated immediately from ThFFF experimental data, when the particle or macromolecule diffusion coefficient is known. This parameter may depend on both electrostatic and non-electrostatic (dispersion) interactions and can be used for their characterization. Also, the thermophoretic mobility may be used for the characterization of surface particle and macro-molecule properties, when the respective theory is developed.

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming. One of the ways that people can fight global warming is to reduce their dependence on non-renewable energy sources like oil and petroleum based products.
