Abstract:
Provided is an apparatus for inhalation of medicine, in which particles in a medicinal aqueous solution, in a liquid aerosol form, are converted to dry medicinal particles by removing moisture therefrom by means of an evaporation unit so as to be inhaled by means of an inhalation device, thereby allowing medicinal particles to penetrate deeply along the respiratory track to the lungs, and thus can be used in the treatment of lung diseases or a variety of other treatments using same, and in which particles of a medicinal aqueous solution in a liquid aerosol form, flowing in from an aerosol unit, are converted to dry medicinal particles by means of a moisture absorbent, thereby allowing simplification and reduction in size of the apparatus for inhalation, and in which a continuous use thereof is possible by means of a simple swap of the moisture absorbent, thereby making maintenance convenient.

Abstract:
The present invention relates to a method for preparing polymer-nanoparticles having a core-shell structure by uniformly coating a polymer on metal and inorganic particles, polymer-nanoparticles prepared thereby, and a polymer-nanoparticle composite comprising the same, and more specifically, a method for preparing polymer-nanoparticles having a core-shell structure by uniformly coating a polymer on metal and inorganic particles, polymer-nanoparticles prepared thereby, and a polymer-nanoparticle composite including the same, wherein when forming a polymer coating layer on surfaces of particles that are not subjected to separate surface treatment, excessive polymers uncoated on nanoparticles are easily removed by adding to an ionic liquid or an apolar solvent so that the polymer coating layer is formed with a nanometer-scale uniform thickness and a dense coating density, thereby showing excellent dispersibility in a polymer matrix.
Abstract:
Provided is a method of manufacturing a conductive metal thin film, the method including: a) heating and stirring a first solution containing a metal precursor, acid, amine, and a reducing agent to synthesize metal nano-particles on which formation of a surface oxide film is suppressed; b) dispersing the metal nano-particles synthesize in step a) in a non-aqueous solvent to prepare a conductive ink composition; c) applying the conductive ink composition onto an insulating substrate; and d) heat-treating the insulating substrate applied with the ink composition to form a conductive metal thin film. With the method of manufacturing a conductive metal thin film according to the present invention, large area conductive thin film may be manufactured as compared with the existing conductive ink composition based on noble metal nano-particles. In addition, the conductive metal thin film having excellent conductivity may be manufactured by suppressing a surface oxide film from being formed.
Abstract:
The present invention relates to a process of preparing of a phosphorus-containing phosphorus-alumina support by a sol-gel method and a cobalt/phosphorus-alumina catalyst where cobalt is supported onto the phosphorus-alumina support as an active ingredient. The phosphorus-alumina support is prepared by a sol-gel method and has wide specific surface area with bimodal pore size distribution and high cobalt dispersion, thereby enabling to increase heat and mass transfer, stabilize the structure by modifying the surface property of alumina and decrease the deactivation rate due to the reduced oxidation of cobalt component during the F-T reaction. When Fischer-Tropsch reaction (F-T) is conducted on the catalyst, the catalyst maintains a superior thermal stability, inhibits the deactivation due to water generation during the F-T reaction and also causes relatively high conversion of carbon monoxide and stable selectivity of liquid hydrocarbons.
