Abstract

The present invention pertains to a microcapsule composition and a method for producing same, wherein alginate gel is formed on the surfaces of calcium carbonate microsphere-conjugated spheroids, thereby encapsulating the spheroids. The method for producing microcapsules has been found to gradually form alginate gel on the surfaces of spheroids containing drugs or physiologically active substances, thereby individually microencapsulating the drugs or physiologically active substances. The drug or physiologically active substance can be positioned in the center of the capsule through a very simple method, and the size of the capsule can be controlled. Thus, very small capsules can be produced in a short period of time as compared to conventional encapsulation methods.

Abstract

The present invention provides a fine particle separating apparatus comprising: a first filter part having a first mesh part, mounted therein, for separating fine particles included in sludge according to size, and having a first section and a second section with the first mesh part therebetween; a first flow path mounted in the first section so as to allow the sludge to flow into the first filter part; a second flow path mounted in the second section so as to allow an effluent, having passed through the first filter part, to flow therein; a third flow path connected from the second flow path so as to discharge the effluent to the outside; a fourth flow path connected from one side of the second flow path, and mounted in the second section so as to allow at least a portion of the effluent flowing into the second flow path to flow to the first filter part; a fifth flow path mounted in the first section so as to allow the effluent, discharged by means of the fourth flow path, to pass through the first filter part and then flow therein; a storage tank through which the effluent flowing into the fifth flow path is discharged; and a first pump for generating a flow of the effluent, wherein the first mesh part is rotatably mounted in the first filter part.

Abstract

An apparatus and method for filter bank multi-carrier signal modulation with a low peak-to-average power ratio (PAPR) in a multiple antenna system are disclosed. According to embodiments of the present disclosure, in a multiple antenna transmission method, after a plurality of transmission candidate signals, which are modulated for each antenna using discrete Fourier transform (DFT) spread filter bank multi-carrier and offset quadrature amplitude modulation (FBMC/OQAM) techniques and are capable of obtaining a single carrier effect, are generated, a transmission candidate signal with a low PAPR can be selected and transmitted, and thus peak-to-average power ratio performance can be effectively improved, and interference between subcarriers can be eliminated by applying an Alamouti coding manner.

Abstract

The present invention relates to a self-assembly preparation method of a nanocomposite material, and more particularly, relates to a self-assembly preparation method of a nanocomposite material comprising steps of: spraying a drug-containing solution onto metal aerosol nanoparticles to form a drug layer on the metal aerosol nanoparticles; and spraying a polymer-containing solution onto the metal aerosol nanoparticles, on which the drug layer is formed, to form a polymer layer on the drug layer, whereby since the method involves no liquid chemical process upon producing the metal aerosol nanoparticles, the processes are simple and can be performed even at a low temperature to suppress deformation of an organic or a drug, and the release rate of the drug, or the like can be easily controlled through metal types of metal aerosol nanoparticles, modification, and the like.
