    Abstract: The present invention mainly provides a non-contact reactor consisting of a reaction vessel having a particularly-designed size, a plurality of injection modules, an agitator, a heat exchange module, and an electrical gate valve module. Operators can inject at least one precursor solution into the reaction nanometer-scale semiconductor crystallites vessel and make the injected precursor solution reach a specific position in the reaction vessel by using the electrical gate valve to control the injection pressure of the injection modules. Moreover, the operators can further control the rotation speed of the agitator through a controller, so as to evenly and quickly mix the injected precursor solution and a specific solution pre-filled into the reaction vessel to a mixture solution; therefore, the acceleration of production rate and the enhance of production yield of the semiconductor nanocrystals are carried out.

  • Publication number: 20150140226
    Abstract: An improved process for diffusing a substrate into a base material is described. Generally, a process is provided for introducing a base material into a salt bath having a substrate with a catalyst. A select amount of catalyst and desired salt bath temperature are provided sufficient to lower the activation energy of the base material such that the substrate is able to easily diffuse into the surface of the base material. Nevertheless, certain substances within the base material may inhibit the diffusion of the substrate into the surface of the base material. Accordingly, a select amount of catalyst and desired salt bath temperature are further provided sufficient to promote leaching of such select substances that inhibit the diffusion of such substrate into such base material. The leached substances are substantially replaced by the diffused substrate.

  • Patent number: 8163348
    Abstract: The invention relates to a method for hot-dip coating hot-rolled steel strip, during which the steel strip passes through a pickling station, a rinsing station, a drying station, a heating furnace and then through a molten bath. The final thickness and the thickness tolerance of the hot-dip coated steel strip are achieved by a controlled thickness reduction in a roll stand in the process line. The achievement of the finished thickness is controlled by at least one thickness measuring unit at the outlet of the roll stand, and deviations upward or downward therefrom are fed back in the form of an actuating signal for actuating the roll stand in order to appropriately increase or decrease the thickness reduction. The invention also relates to an installation for producing a steel strip of the aforementioned type.

  • Patent number: 8163641
    Abstract: A charge transfer mechanism is used to locally deposit or remove material for a small structure. A local electrochemical cell is created without having to immerse the entire work piece in a bath. The charge transfer mechanism can be used together with a charged particle beam or laser system to modify small structures, such as integrated circuits or micro-electromechanical system. The charge transfer process can be performed in air or, in some embodiments, in a vacuum chamber.

  • Patent number: 8084099
    Abstract: A process of coating fibers with a metal by a liquid method is disclosed. In this process, a fiber is drawn through a bath of molten liquid metal so as to coated with the latter, the liquid metal bath being maintained in a crucible of the “levitation” type, which at least partly eliminates contact between the liquid metal and the crucible. The bath is fed with metal, during the process, by a metal powder. Accordingly, the molten metal bath is fed in a simple and effective manner.

  • Patent number: 8070860
    Abstract: An H2-permeable membrane system (117) comprises an electroless-deposited plating (115) of Pd or Pd alloy on a porous support (110, 110?). The Pd plating comprises face-centered cubic crystals cumulatively having a morphology of hexagonal platelets. The permeability to H2 of the membrane plating (115) on the porous support is significantly enhanced, being at least greater than about 1.3×10?8 mol·m?1·s?·Pa?0.5 at 350° C., and even greater than about 3.4×10?8 mol·m?1·s?1·Pa?0.5. The porous support (110, 110?) may be stainless steel (1100 and include a thin ceramic interlayer (110?) on which the Pd is plated. The method of providing the electroless-deposited plating includes preheating a Pd electroless plating solution to near a plating temperature substantially greater than room temperature, e.g. 60° C., prior to plating.

  • Patent number: 8048192
    Abstract: Provided are methods and systems for generating nanoparticles from an inorganic precursor compound using a hydrothermal process within at least one CSTR or PFR maintained at an elevated temperature and an elevated pressure and a treatment vessel in which this reaction solution can be applied to one or more catalyst substrates. In operation, the reaction solution may be maintained within the CSTR at a substantially constant concentration and within a reaction temperature range for a reaction period sufficient to obtain nanoparticles having a desired average particle size of, for example, less than 10 nm formation and/or deposition. Variations of the basic method and system can provide, for example, the generation of complex particle size distribution profiles, the selective deposition of a multi-modal particle size distribution on a single substrate.

  • Patent number: 8039119
    Abstract: Orientation degree and smoothness of a substrate surface better than those of conventional ones are provided in a textured substrate for epitaxial thin film growth. The present invention is a textured substrate for epitaxial film formation, including a crystal orientation improving layer made of a metal thin film of 1 to 5000 nm in thickness on the surface of the textured substrate for epitaxial film formation having a textured metal layer at least on one surface, wherein differences between orientation degrees (?? and ??) in the textured metal layer surface and orientation degrees (?? and ??) in the crystal orientation improving layer surface are both 0.1 to 3.0°. Further, when another metal different from the metal constituting this textured substrate crystal orientation improving layer is added equivalent to a thin film which is 30 nm or less, and subsequently is subjected to heat treatment, the smoothness of that surface can be improved.
