A system and an on-board-diagnosis method is provided for an exhaust aftertreatment system of an engine including a diesel particulate filter unit which encompasses a particulate filter in which soot can be oxidized by NO2 and constituents of the exhaust gas are deoxidized in a nitrogen-oxides reduction unit arranged downstream of the diesel particulate filter unit, wherein the exhaust gas flows from the diesel particulate filter unit to the nitrogen-oxides reduction unit. The on-board-diagnosis method includes estimating an NO2 content upstream of the nitrogen-oxides reduction unit, measuring at least one of an NOx or NO2 content upstream of the nitrogen-oxides reduction unit, performing a comparison between the estimated and the measured contents, and, based on the result of the comparison deciding on at least one conditioning step of the diesel particulate filter unit.

A laser cladding or plasma transferred arc overlay welding process may be used advantageously to apply and to control the material properties of a coating designed for protecting the substrate against wear, corrosion and oxidation at elevated temperature. Furthermore, a laser cladding or plasma transferred arc overlay welding process may be used to apply the coating alloy materials in applications where traditional thermal spray or weld-applied coatings are not practical. By using these welding methods very good bonding is achieved by fusion during welding. At the same time the properties of the clad layer is preserved by the limited dilution typical of these two welding methods compared traditional overlay welding, by e.g. Gas Tungsten Arc Welding and the like.

Hard-material-coated bodies composed of metal, cemented hard material, cermet or ceramic, coated with a TiSiCN composite layer or with a multilayer layer system which contains at least one TiSiCN composite layer. The TiSiCN composite layer is a nanocomposite layer which has been produced by a thermal CVD process without additional plasma excitation and contains a nanocrystalline phase composed of TiC_xN_1-x having a crystallite size in the range from 5 nm to 150 nm and a second phase composed of amorphous SiC_xN_y. The layer is characterized by a high hardness, a high oxidation and heat resistance and a high adhesive strength.

An object of the present invention is to provide a novel poly(cyclic conjugated diene) and a process for producing the same; and a modifying product, a hydrogenated product, and a poly(cyclic conjugated diene) comprising phenylene thereof. The present invention is a polymer having molecular structure units derived from cyclic conjugated diene monomers having a polar group. The basic skeleton of the molecular structure units of this polymer preferably has a 5-8-membered cycloalkene ring. For polymerizing reaction of the cyclic conjugated diene monomer, it is preferred to use a catalyst such as a Ni-based catalyst, and conduct the reaction in a non-polar solvent containing a basic compound or in an aromatic halide solvent. The Ni-based catalyst is used for the polymerization to obtain a polymer having high crystallizability. Its substituents are removed to obtain a paraphenylene polymer.

A hard coating includes a three kinds of layers that are alternately laminated. The three kinds of layers consist of a single composition layer and two kinds of nanolayer-alternated layers.

The invention discloses a method for directionally oxidizing crude oil in soil by passivating SOM through iron regulation and control and passivated soil, wherein the method comprises the following steps: passivating organic matters in oil-containing soil: uniformly mixing the oil-containing soil, ferrous salt, a passivating agent and water, and carrying out oscillation passivation to obtain the passivated SOM oil-containing soil; and mixing the passivated SOM oil-containing soil with an oxidant and water, and carrying out continuous oscillation oxidation reaction to finish the process of directionally oxidizing the crude oil in the soil by passivating the SOM through iron regulation and control. According to the method, the consumption of free radicals of protein I, the consumption of free radicals of protein II and the consumption of functional groups C=O in the directionally oxidized soil are reduced by passivating the SOM through iron regulation and control; the directional oxidation amount is as high as 3100 mg/kg. The efficiency of directly oxidized crude oil by .OH is improved.
