Abstract: The present invention addresses the problem of providing a new method for increasing the production of fine particles. Using at least two types of fluids to be processed, a raw material fluid containing at least one type of fine particle raw material and a fluid for treating the fine particle raw material, fine particles are obtained by mixing the fluids to be processed in a thin film fluid formed between at least two processing surfaces which are disposed to be faced with each other so as to be able to approach to and separate from each other, at least one of which rotates relative to the other. At this time, the production of the fine particles is increased by introducing the raw material fluid from the centers of the processing surfaces.

Abstract: Methods are provided for evaluating the ability of a tire to release materials from its tread during rotation. A tire tread is rotated about an axis while images of the tread are recorded to capture the effect of centrifugal forces on materials that have been loaded into the tread. The images are then used to quantify the location of certain events during the rotation of the tire tread such as when e.g., materials first began releasing from the tread during rotation and/or the rate of such release. These events can be correlated with other variables such as the rpm, centrifugal acceleration, and/or time at which such events occurred. By comparing these quantitative results for different tread patterns, the effect of differences between tread patterns can be evaluated to develop and improve the self-cleaning ability of a tire.
