Abstract:
The present disclosure relates to a method for the selective adsorption of a noble metal catalyst onto a surface of a polymer. More particularly, the method of the present invention includes a first step of masking with a photo mask, the surface of a polymer adsorbed with a photosensitive metal ion, and radiating light onto the surface of the polymer such that the photosensitive metal ion on the unmasked surface is oxidized, and a second step of permitting the photosensitive metal ion which is not oxidized in the first step to react to a noble metal catalyst such that the noble metal catalyst is adsorbed onto the surface of the polymer.
Abstract:
Disclosed is an atmospheric pressure plasma apparatus for enhancing and or controlling the dissociation of a secondary gas by converting a source gas into a plasma state at atmospheric pressure and controlling the interaction between that plasma and the secondary gas using porous metal, and ceramic tubes to create a path having controllable isolation from the region where plasma is generated.

Abstract:
A method for preparing permanently hydrophobic aerogel and permanently hydrophobic aerogel prepared by the method. The method comprises adding sodium silicate to HCl at 30 to 90° C. until an acidity reaches pH 3-5, to form silica hydrogel under acidic conditions of pH 3-5, washing the silica hydrogel with distilled water using a mixer, followed by filtering, adding the silica hydrogel to a silylating solution of silylating agent in n-butanol at pH 1-5 using an acid selected from hydrochloric acid, sulfuric acid, phosphoric acid and nitric acid, to simultaneously conduct silylation and solvent replacement, and drying the silica hydrogel; The method has the following advantages; i) silylation and solvent replacement can be simultaneously conducted, ii) n-butanol is used as a reaction solvent instead of methanol upon silylation, thus obtaining a thermal conductivity comparable to conventional aerogel powders, iii) silylation is conducted under improved conditions, i.e., strong acidic conditions of pH 1-5, and as a result, all of the aerogel powders can be reacted with a silylating agent, thereby obtaining permanently hydrophobic aerogel, iv) the washing with a mixer makes the amount of removed sodium ions uniform, thus it is suitable for mass-production, and v) the method provides a relatively simplified procedure and the use of the silylating agent in a small amount enables low costs and mass-production.
Abstract:
Disclosed herein is an apparatus and method for searching for 3-dimensional shapes. The apparatus includes, an input means, an acquisition module, a storage means, a comparison and search module, an output means, and control means. The input means receives 3-dimensional image data. The acquisition module acquires a 2-dimensional image data group about the shape of an object represented by the 3-dimensional image data. The comparison and search module compares the respective data of the acquired 2-dimensional image data group with the respective data of the 2-dimensional image data groups that are previously stored in the storage means, and searches for 3-dimensional image data. The control means controls the modules and the means.
Abstract:
Disclosed are a BIPV-applicable high-power shingled photovoltaic module and a manufacturing method therefor, the module comprising: a solar panel having a shingled array structure; a first sealant stacked on the solar panel so as to protect the solar panel; a second sealant stacked under the solar panel in order to protect the solar panel; a front cover through which the sunlight passes, and which is stacked on the first sealant so as to protect the first sealant; and a first back sheet stacked under the second sealant in order to protect the solar panel from the outside environment, and thus aesthetic impression and reflectance reduction of a high-power shingled photovoltaic module are increased so that use as an external design element of a building is possible.
Abstract:
Provided are a reactor for producing hydrogen and carbon through methane pyrolysis by a thermal storage method, and a combination reactor including the same, wherein the reactor includes a reaction unit in which pure-oxygen combustion of carbon and pyrolysis of methane are carried out, a first accommodation unit that supplies oxygen and the carbon to the reaction unit or accommodates carbon and hydrogen obtained by the pyrolysis of the methane, a flame supply unit that generates a flame within the reaction unit, a thermal storage unit that is located within the reaction unit and stores combustion heat generated during the pure-oxygen combustion of the carbon, and a second accommodation unit that accommodates carbon dioxide produced by the pure-oxygen combustion of the carbon or supplies methane to the reaction unit, wherein the pure-oxygen combustion of the carbon and the pyrolysis of the methane are alternately carried out.
Abstract:
The present disclosure relates to a modified epoxy resin having a weight average molecular weight of 5,000 to 25,000 and a polydispersity index of 5.0 to 20.0, and comprising (1) an epoxy-derived unit and (2) a modifier-derived unit, a preparation method thereof, a composition comprising the same, and uses thereof. When the epoxy composition comprising the modified epoxy resin according to the present disclosure is cured, the epoxy composition has a lowered coefficient of thermal expansion (CTE), i.e., improved thermal expansion properties, due to curing-induced phase separation (morphological properties) into an epoxy region and an acrylic region. The modified epoxy of the present disclosure and the epoxy composition comprising the same are suitable as adhesives for semiconductor packaging.
