An ultra-high voltage direct current (DS) power cable may be provided via a conductor formed by twisting a plurality of strands, an inner semiconducting layer surrounding the conductor, an insulating layer surrounding the inner semiconducting layer; and an outer semiconducting layer surrounding the insulating layer, wherein the insulating layer is formed of an insulation composition containing a polyolefin resin and a crosslinking agent, and the insulating layer is divided into three equal parts in a thickness direction, the three equal parts including an inner layer, an intermediate layer and an outer layer.

Ultra-high voltage direct current power cable

The present invention relates to a solid colonic purgative for oral application, containing anhydrous magnesium sulfate, potassium sulfate, anhydrous sodium sulfate, and, additionally, simethicone. The present invention is more satisfactory in the colon cleansing effect even with the doses reduced by up to about 20 percent compared to those of a conventional colonic purgative consisting of anhydrous magnesium sulfate, potassium sulfate and anhydrous sodium sulfate. Besides, the present invention, due to the reduced doses, has less unpleasant taste or odor caused by the main ingredients and requires a less intake of the preparation and water, improving drug compliance significantly. Further, unlike the conventional solid colonic purgative, the present invention can be prepared into tablets without using a water-soluble lubricant. In other words, the present invention can be formulated into a solid preparation for oral application by using a water-soluble lubricant, or even without using any water-soluble lubricant.

Provided is an insulation composition having a low dielectric constant and a cable including an insulation layer formed of the insulation composition. More particularly, the present invention relates to an insulation composition for reducing a space charge to increase superimposed impulse breakdown strength when impulse voltages overlap during application of a direct-current (DC) voltage, having a low dielectric constant, and improving impulse breakdown strength, and a cable including an insulation layer formed of the insulation composition.

Insulation composition having low dielectric constant, and cable including insulation layer formed therefrom

A block copolymer is provided. The block copolymer according to an exemplary embodiment includes a first block represented by Chemical Formula 1 and a second block represented by Chemical Formula 2: wherein COM1 and COM2 are independently selected from a polystyrene moiety, polymethylmethacrylate moiety, polyethylene oxide moiety, polyvinylpyridine moiety, polydimethylsiloxane moiety, polyferrocenyldimethylsilane moiety, and polyisoprene moiety, R1 is hydrogen or an alkyl group with 1 to 10 carbon atoms, Ph is a phenyl group, a is 1 to 50, R2 is hydrogen or an alkyl group with 1 to 10 carbon atoms, and b is 1 to 50.

Block copolymer, method of forming the same, and method of forming pattern

An approach is provided for manufacturing a nanostructure. A first thin film including a first block copolymer is formed on a substrate. A guide pattern is formed on the first thin film. A second thin film including a second block copolymer is formed between portions of the guide pattern. The second thin film is cured. The first block copolymer is a cylinder-type and the second block copolymer is a lamella-type.

Method of manufacturing nanostructure and method of forming pattern using the same

A method of forming patterns includes forming a layer composed of a ketene based random copolymer on a substrate, forming a block copolymer on the ketene based random copolymer layer and patterning the ketene based random copolymer layer by removing a part of the block copolymer and a portion of the ketene based random copolymer layer.

There is provided a method of preparing biodegradable dual pore polymer scaffolds, comprising the steps of: maintaining a polymer solution containing a biodegradable polymer, an effervescent mixture of carbonate and organic acid, and solvent at a temperature range of &#x2212;196&#xb0; C. to ambient temperature so as to evaporate the solvent and produce a polymer sample; and foaming the polymer sample in a mixed solution of water and alcohol. According to the present invention, the pore size of the polymer scaffolds can be easily controlled, and biodegradable polymer scaffolds can be more simply prepared compared to conventional methods such as salt leaching technique, phase separation technique or gas foaming technique. Further, since the biodegradable polymer scaffolds prepared according to the present invention have a high surface area and porosity without formation of skin layer, secretion of toxic substances and remnant phenomenon, they can be advantageously used for regenerating almost all living tissues and organs in tissue engineering.
