The invention provides a fibre cloth inspecting method for inspecting a fibre cloth regarding sparse density, filament break, various kinds of mark, fabric runs, break, weaving validation, and dyeing uniformity. A slide, which may be in the form of a tube or trough, transports particles from an upper zone downward to a lower zone at a different horizontal position, thereby changing the horizontal position of the particle and creating lateral mixing in the fluidized bed. The at least two of the first plurality of alignment features are positioned asymmetrically with respect to the base. The ceramic matrix includes a dispersion of the semiconductor nano-particles therein.
