Provided is a liquid cell for an electron microscope according to an embodiment of the inventive concept, including a lower window layer, an upper window layer above the lower window layer, and a separation film disposed between the upper window layer and the lower window layer so as to separate the upper window layer and the lower window layer from each other. An upper space may be defined by the upper window layer and the separation film, and a lower space may be defined by the lower window layer and the separation film. The upper window layer, the lower window layer, and the separation film may include the same material.

Liquid cell for electron microscope and manufacturing method thereof

A ferroelectric thin film and a forming method thereof are provided. The method of forming a ferroelectric thin film according to embodiments of the present invention comprises forming a sacrificial seed layer on a first substrate, forming a ferroelectric thin film on the sacrificial seed layer, and transferring the ferroelectric thin film to a second substrate. The ferroelectric thin film according to embodiments of the present invention is formed by the method.

Ferroelectric thin film and forming method thereof

A method of forming a compound structure according to embodiments of the present disclosure comprises loading a metal precursor on a substrate, providing a chalcogen precursor to the substrate, and reacting the chalcogen precursor with the metal precursor. The metal precursor comprises transition metal nanoparticles. The compound structure has a 2-dimensional structure.

Method of forming compound structure with 2-dimensional structure

An apparatus and method for determining an amount of chemical input, and more particularly to an apparatus and method for determining the amount of a chemical to be added, which is necessary to achieve target water quality, wherein a required chemical concentration can be accurately calculated based on the temperature of the water and the target turbidity of the water includes an information-receiving unit configured to receive at least one of environmental information, chemical information, and water-quality information of the water present in a specific area and a chemical input determination unit configured to derive a multiple regression equation based on the received environmental information, chemical information, and water-quality information and to determine the future input of a chemical that is added to satisfy a target turbidity of the water present in the specific area based on the multiple regression equation.
