Abstract:
A nozzle, a device, and a method for high-speed generation of uniform nanoparticles allow a particle generation gas formed of carbon dioxide to pass through the nozzle, thereby forming uniform nanoparticles at high speed. An orifice that adjusts an opening and closing cross-sectional area of a throat of the nozzle is provided to cause uniform nuclei generation without an additional cooling device, a dilating portion that has a cross-sectional area and a dilation angle increasing toward an outlet side of the nozzle is provided to grow the nuclei through a first dilation portion (having a relatively gradual dilation angle) and thus cause particle generation, and the generated particles are accelerated through a second dilating portion that has a steeper dilation angle than the first dilating portion.
Abstract:
Provided are a recombinant polypeptide in which a small leucine-rich proteoglycan mimetic sequence is attached to a terminal of a mussel adhesive protein, a composition for wound healing including the same, a bioadhesive material, and a preparation method thereof. According to the present disclosure, the recombinant polypeptide in which the small leucine-rich proteoglycan mimetic sequence is attached to the terminal of the mussel adhesive protein has an excellent epidermal regeneration effect in which the wound site is uniformly restored by promoting rapid wound healing at the wound site when being applied to the wound site and inducing formation of collagens which are arranged and concentrated at the wound site, and thus can be usefully used as various drugs, cosmetics, and quasi-drugs.

The nanowire has a content of the silicon (Si) higher than a content of the germanium (Ge) at a surface thereof, and has the content of germanium (Ge) higher than the content of the silicon (Si) at an inner part thereof.
Abstract:
Provided is a scanner for photoacoustic tomography including: a mirror which reflects light and a photoacoustic signal for the photoacoustic tomography; a first driving member which is attached with the mirror; a second driving member which is connected to the first driving member; first driving force supply units which are disposed under two ends of the first driving member in a first direction to exert a driving force for allowing the first driving member to perform tilting movement in the first direction; and second driving force supply units which are disposed under two ends of the second driving member in a second direction to exert a driving force for allowing the second driving member to perform tilting movement in the second direction.
Abstract:
This invention relates to a method of fixing carbon dioxide by condensation polymerization in an acidic aqueous medium, thereby increasing fixation efficiency and remarkably reducing the volume of generated material compared to conventional carbon dioxide fixation methods; a polymer material prepared by the method; and a method of recovering carbon therefrom. According to the current invention, the method of fixing carbon dioxide is characterized by introducing carbon dioxide pressurized to a pressure higher than atmospheric pressure into a reactor containing a acidic aqueous medium, so that carbonic acid resulting from dissolving carbon dioxide is made into a polymer material by condensation polymerization, thereby fixing carbon dioxide, and heating the polymer material so as to recover carbon.
