Abstract: Alkanes are catalytically oxidized in air or oxygen using iron-substituted polyoxoanions (POAs) of the formula:H.sub.e-z ?(n-C.sub.4 H.sub.9).sub.4 N!.sub.z (XM.sub.11 M'O.sub.39).sup.-eThe M' (e.g., iron(III)/iron(II)) reduction potential of the POAs is affected by selection of the central atom X and the framework metal M, and by the number of tetrabutyl-ammonium groups. Decreased Fe(III)/Fe(II) reduction potential has been found to correlate to increased oxidation activity.

Abstract: A watchband has a flexible outer band with hook-and-loop fasteners (e.g., Velcro) on its inner surface, and a flexible inner band with complementary hook-and-loop fasteners on its outer surface. The fasteners on the inner band removably engage the fasteners on the outer band to fasten the watchband about the wearer's wrist. The outer band includes an outer layer of decorative material, a layer of hook-and-loop fastener material on its inner surface covered by the decorative material, and a thin flexible plastic strip coated with adhesive that bonds the decorative material to the fastener material. This construction permits the outer band to be easily trimmed to a desired length to form a continuous band around the wearer's wrist with the ends of the outer band abutting each other. Similarly, the inner band can be easily trimmed to a desired length so that the outer band substantially conceals the inner band when fastened around the wearer's wrist.
