An aerosol generator, in particular a soot generator. The aerosol generator includes a combustion chamber, in which fuel can be burned with an oxidizing agent in at least one soot-particle-creating flame, and a fluid feeding device for feeding fuel and an oxidizing agent into the combustion chamber. The fluid feeding device has at least three feed lines, the outlet-side end portions of which run parallel, so that at least three fluids of different types, in particular gases, can be introduced into the combustion chamber unmixed and in a parallel inflow direction.

A rubber composition having improved antiozonation performance comprising a substituted hydroxyl-phenyl-p-(hydroxy)phenylenediamine. Such a composition is particularly suitable for rubber articles. The improved rubber composition possesses a long lasting antiozonation performance, slowing migration through the rubber article and reducing effluence of the antiozonant. Such rubber articles may include rubber pneumatic tires, solid tires, non-pneumatic tires, belts, hoses, cables, automotive mounts, bushings and general mechanic products that are exposed to continuous and intermittent dynamic operation conditions and require protection from ozonation.

A method for producing a submicron-/nano-jute carbon/epoxy composite anti-corrosion coating is described. The method includes heating a jute stick, grinding the jute stick to form a first powder; pyrolyzing the first powder to form a pyrolyzed carbon; grinding the pyrolyzed carbon to form a second powder; ball milling the second powder under the wet conditions to form a submicron-/nano-jutecarbon; mixing the submicron-/nano-jutecarbon, and an epoxy resin to form a first mixture; mixing a hardener with the first mixture to form a second mixture, and coating the second mixture on a mild steel substrate and curing to form the submicron-/nano-jutecarbon/epoxy composite anti-corrosion coating.
