Future Development

A search for the historical origins of a scientific discovery is often a difficult task but, with regard to the rapid advances in separation science in general, and of particle size separations in particular, the long-term prediction of progress is almost a 'mission impossible'. However, cautious examination of the state of the art and of potential exigencies concerning particle size separations, allows a few statements about what is likely to happen in the near future to be made.

Further increases in efficiency, resolution and selectivity represent a permanent challenge in particle size separations. An ideal is to separate two partic-ulate species differing by a minimal increment in terms of a 'construction' unit, e.g., one molecule or atom, and not only in terms of 'size increment' which is a rather arbitrary choice.

Increase of the separation speed can be an important factor whenever the separated particles exhibit an evolution in time and it is necessary to capture information on the actual PSD at a given moment. Many biological concepts are approached in this way. The ways to be explored lead to more extensive use of supercritical fluids allowing substantial increase of transport coefficients.

Most recent methods and techniques of particle size separations exploit simple physical and physicochemical principles single driving forces leading to the separation. Coupling of two or more physical fields and field gradients as selective driving forces and their combinations with nonselective transport due to the carrier fluid flow seems to be a recently emerging approach.

Large-scale particle size separations represent important parts of many industrial technologies. The performance of a large-scale separation is often lower in comparison with an essentially identical technique applied under analytical-scale conditions. The optimization of large-scale separation processes in order to approach the performances comparable with analytical-scale conditions. The optimization of large-scale separation processes in order to approach the performances comparable with analytical-scale separations has a potentially important economic impact.

The permanent search for noninvasive conditions in particle size separations is an important field of activity related to fundamental research in the life sciences and also to many important biotechnologies.

These directions of potential future progress in the domain of particle size separations are certainly not exhaustive but they represent an overview of, probably, the most important activities in research and development.

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.
