The invention relates to high shearing stress induced desulfurization of recycled tyre rubber, and a modified method. Linear high-molecular substances accounting for 5 to 50 percent of the percentage content of the reagent total weight, recycled tyre rubber powder accounting for 49 to 94 percent of the percentage content of the reagent total weight, and stabilization accessory ingredient accounting for 0.01 to 1.8 percent of the percentage content of the reagent total weight are mixed; the mixture is added into a high rotation speed and high shearing type co-rotating twin-screw extruder all together to be molten and extruded to operate the desulfurization reaction; through water cooling, pelleting, and drying or through roll calendering cooling and sheeting out, desulfurization modified regenerated rubber resultant is obtained. The invention integrates the desulfurization reaction, as well as the smelting process, the refining process, and the rubber filtering process into a whole, the efficiency of the desulfurization process is high, the production rate is high, the energy consumption is low, and the macro scale and the large scale are easy; the desulfurization reaction is easy to be controlled; the pollution of the reaction process to environment is small, and the mechanical property of the resulfurized material of the desulfurization resultant is good.

The present invention is directed to a rut resistant coating and a method for applying the rut resistant coating on an existing surface for increasing resistance to high vertical and horizontal strains and high shear stresses. The method includes applying a binding material layer of the rut resistant coating on the existing surface to provide a substantially impermeable moisture barrier to the existing surface, the binding material layer containing less than about 11% of the total binding material of the rut resistant coating. After applying the binding material layer, an aggregate mixture layer is applied on the binding material layer to provide the wear surface of the rut resistant coating and support and structure to the rut resistant coating to resist rutting, the aggregate mixture layer containing an asphalt solution.

Described are embodiments that employ ultrasonic energy to selectively lyse larger adipose cells in a suspension containing adipose cells of different sizes resulting in a suspension in which the only viable cells are the small adipose cells and stem cells. Embodiments provide for generating an acoustic standing wave field of sufficient intensity and proper geometry, that high shear stress is induced on the cell membranes of cells larger than a predetermined size. The remaining small adipose cells can be physically separated from the suspension after the suspension is subjected to the acoustic standing wave field.
