    Abstract: A method providing damping during an abrading operation is provided. The method includes removably coupling the abrasive wheel to a hub. The abrasive wheel has an outer circumference and an inner circumference. A layer of abrasive material extends between the inner and outer circumference. The method also includes abrading a worksurface by contacting the abrasive disc to the worksurface. The hub includes a housing and a plurality of damping units within the housing. The plurality of damping units are shaped to reduce vibrations during a grinding operation.

    Abstract: Metal-containing sorbent materials are provided, methods of making the metal-containing sorbent materials, methods of using the metal-containing sorbent materials, and metal complex-containing composite materials resulting from the sorption of basic, nitrogen-containing compounds on the metal-containing sorbent materials are provided. The sorbent materials are prepared by incorporating divalent metals into a precursor material that is formed by treating a porous siliceous material having mesopores with a silane or disilazane surface treatment agent. The metal-containing sorbent materials can be used to capture basic, nitrogen-containing compounds having a molecular weight no greater than 150 grams/mole.
