Methods and apparatus for protecting the thin films during chemical and / or thermal edge strengthening treatment. In one embodiment, a portion of each individual sheet is laminated. Pairs of sheets are then sealed together such that the thin film sides face inward to form a thin film sandwich. In some embodiments, the sandwich in then immersed in a chemical strengthener. In other embodiments, a localized treatment is applied to the unstrengthened edges.

A method of forming a metal wiring in a semiconductor device. A copper wiring is formed by means of CECVD method by which a chemical enhancer layer is utilized for increasing the deposition speed of copper. The damascene pattern is filled by means of MOCVD method using a copper precursor in order to increase the deposition speed. The chemical enhancer layer rises to the surface of copper after deposition of copper by a CECVD method and then the relatively high resistivity chemical enhancer layer that has risen to the surface of copper by plasma process is removed. Therefore, the ultra-fine damascene pattern can be rapidly filled with copper without increasing the resistance of the copper wiring.

A method and apparatus are provided for reducing emissions of particulates from diesel engines. Exhaust is passed through a diesel particulate filter having at least two stages comprised of (a) a catalyst section having a platinum group metal catalyst on contact surfaces within the catalyst section and (b) a filter section comprised of passages effective to remove particulates from a moving stream of combustion gases generated by combusting the fuel in the engine and holding them therein to permit their oxidation. Carbon removal is enhanced by utilizing levels of platinum group metal composition, cerium compositions, fuels and / or optional chemical enhancers to generate NO2 in the catalyst section in amounts sufficient to form cerium nitrates in the filter section. The cerium oxide is associated with and maintains dispersion of the platinum in the filter section, and the cerium nitrates are available at the surface and within the soot particles to provide enhanced soot oxidation at a lower balance point.

A system and method for estimating a concentration of monoethanolamine (MEA) in a fluid. A substrate for supporting a sample of the fluid during testing includes a carbon nanotube mat layer, a silver nanowire layer disposed on the carbon nanotube mat layer, and a chemical enhancer layer disposed on the silver nanowire layer. A sample of the fluid is placed on the substrate, and the fluid sample is radiated with electromagnetic radiation at a selected energy level. A detector measures a Raman spectrum emitted from the sample in response to the electromagnetic radiation. A processor estimates the concentration of MEA in the sample from the Raman spectrum and adds a corrosion inhibitor to the fluid in an amount based on the estimated concentration of MEA to reduce the concentration of MEA in the fluid.

The invention discloses a shale gas mining device and method with combination of laser and water jet technologies. The device mainly comprises a laser head, a water jet gun head and others. The laser head can emit controllable energy lasers, the water jet gun head jets active liquid to the surface of shale, the lasers are utilized for heating the active liquid to generate local temperature rise and thermal reaction liquid, an explosive chemical reaction is carried out in the liquid to generate high pressure to crash the shale, shale particles are smaller, and more shale gas is released. In this way, the shale is crashed rapidly, and the shale gas is efficiently obtained. The method can replace a hydraulic fracturing shale crashing mode used in the prior art, in this way, working efficiency can be substantially improved, and the shale gas can be efficiently mined. The active liquid for usage does not contain a chemical reinforcing agent and other contamination reagents, and will not cause water pollution, chemical pollution, methane pollution and other environmental problems.

A method of forming a metal wiring in a semiconductor device is disclosed. In order to improve a low deposition speed in the process technology by which a damascene pattern of an ultra-fine structure is filled with copper by CVD method, a CECVD method is disclosed by which a chemical enhancer layer for increasing the deposition speed of copper is formed and the damascene pattern is then filled by means of MOCVD method using a copper precursor which forms a copper wiring. A diffusion prevention film is formed on the sidewall of the damascene pattern in the shape of a spacer in order to prevent an increase of the via resistance by the diffusion of copper into the sidewalls of the damascene pattern. A chemical enhancer layer is selectively formed on a lower metal layer that is exposed by the damascene pattern, thus allowing a selective partial filling of the damascene pattern. Therefore, copper filling in an ultra-fine structure is facilitated which also minimizes the electrical resistivity of the copper wiring.
