摘要:
Disclosed herein is a carboxylic ester dispersant shown in the following Formula 1 and a sulfide phosphor paste composition containing the dispersant. The dispersant improves the dispersibility of the sulfide phosphor paste composition and prevents oxidation by a solvent, thus improving processability and the luminescent properties of a phosphor film made from the paste and of a display produced using the film. In Formula 1, n is 1-20.

Disclosed is a method for surface treatment of nickel particles using an acid solution, comprising mixing a weak acid with a buffer solution to prepare an acid solution having a pH of 2 to 5; mixing the acid solution with nickel particles; and filtering, washing and drying the mixed solution. Nickel particles treated by an embodiment of the method of present invention are free of impurities remaining on particle surfaces and thus have smooth surfaces and increased tap density, and use thereof may enable efficient production of a multi-layer ceramic capacitor (MLCC).
摘要:
A method for surface treatment of nickel nanoparticles using an organic solution, including dispersing nickel nanoparticles in a reductive organic solvent to obtain homogeneity; heating the dispersion of nickel nanoparticles; and separating the solution after treatment, washing and drying. Nickel nanoparticles treated by this method are preferably substantially free of impurities remaining on particle surfaces and thus have smooth surfaces and increased tap density, and the use thereof enables efficient production of a multi-layer ceramic capacitor.
摘要:
A method for separating semiconducting and metallic carbon nanotubes by selectively plating metallic carbon nanotubes via electroless plating to precipitate the plated metallic carbon nanotubes and filtering the precipitated metallic carbon nanotubes. According to an example method, metallic and semiconducting carbon nanotubes may be effectively separated from each other in a simple manner and/or at a low cost.

摘要:
A parking lever includes a base plate, a parking lever rotatably mounted to the base plate and having a parking brake cable connected thereto, a ratchet disposed on the base plate, a pawl lever rotatably mounted to the parking lever, a button mounted to the parking lever, a rod operably connecting the button to the pawl lever, and a stopper mounted to the parking lever. The lever is moveable from a released state to a parking state in which the pawl lever is engaged with the ratchet. In one embodiment, the parking lever is not released by operation of only the button to prevent accidental release of the parking brake.
