A catalyst, its method of preparation and its use for producing aliphatic ketones by subjecting alkanes C3 to C9 to a gas phase catalytic oxidation in the presence of air or oxygen, and, optionally, steam andor one or more diluting gases. Particles of the wear alloy coating material are directed toward a target surface of the substrate at a velocity sufficiently high for the particles to deform and to adhere to the target surface. The cap has a flat, plate shaped base, and a cylindrical lip that extends upright from the base. Additionally, the vehicle may comprise one or more cameras configured to transmit a two dimensional, three dimensional, or 360\xb0 panoramic view from the vehicle. The display driver reports a number of virtual displays to an operating system and provides pointers to addresses associated with the portions of the frame buffer.
