In some embodiments, a pattern film includes a base layer, and a spacer pattern formed on the base layer, the spacer pattern comprises a partition wall spacer comprises a plurality of spacer dots and a spacer line connecting the spacer dots, and a ball spacer, the ball spacer is one of embedded in, partially embedded in, or in contact with the partition wall spacer, when any 3 or more spacer dots are selected, the spacer line forms a closed figure having the selected spacer dots at the vertices thereof, the selected spacer dots are not present inside the closed figure, a length of at least one side of the closed figure is different from lengths of the remaining sides, and each spacer dot has irregularity of 50% or greater.

Pattern film, method for manufacturing pattern film, and transmittance variable device comprising same

A catalyst for oxidative dehydrogenation of butene and a method for producing the same are described. The method includes forming a first coprecipitate, forming a second coprecipitate, and mixing the first and second coprecipitates under conditions that product a catalyst having a favorable surface chemistry profile.

Method for producing a catalyst for oxidative dehydrogenation of butene

A pattern film, a transmittance variable device comprising the same, and a method for manufacturing a transmittance variable device are disclosed herein. In some embodiments, a pattern film includes a first base layer, and a spacer pattern formed on the first base layer, wherein the spacer pattern comprises a partition wall spacer and a ball spacer, wherein the ball spacer is one of embedded in, partially embedded in, or in contact with the partition wall spacer, and wherein an area of the spacer pattern per unit area of the first base layer is 5% or greater to 17% or less.

Patterned film, variable-transmittance device comprising same, and method for producing variable-transmittance device

The present invention relates to a catalyst for oxidative dehydrogenation of butene and a method for producing the same. The catalyst for oxidative dehydrogenation of butene has a large amount of Mo&#x2014;Bi phase acting as a reaction active phase on the surface, and therefore, can exhibit high catalytic activity, high conversion rate and high butadiene selectivity in the oxidative dehydrogenation of butene.

Catalyst for oxidative dehydrogenation of butene and method for producing the same

According to the present invention, a composite including amorphous iron molybdate islands, shows a smaller island size and a uniform distribution of islands compared with a conventional composite including crystalline islands, and thus has a higher specific surface area, thereby exhibiting excellent activity as a catalyst.

Molybdenum oxide composite and preparation method therefor

The present specification relates to a preparation method for rod-shaped molybdenum oxide and a preparation method for a molybdenum oxide composite, the preparation method for rod-shaped molybdenum oxide according to the present invention may be carried out under low temperature and pressure conditions, and thus has an advantage in that it is possible to mass produce rod-shaped molybdenum oxide, and the preparation method for a molybdenum oxide composite according to the present invention has an advantage in that the molybdenum oxide composite may be synthesized at a temperature which is equal to or less than the boiling point of ethanol, and the amount of an ethanol solvent used is reduced.
