Disclosed is an apparatus for graphene wet transfer, which includes: a reservoir body having at least two reservoirs; a barrier structure located on the reservoir and having at least one separated space formed by barriers; and a substrate frame located below the barrier structure and having at least one substrate accommodation groove for accommodating a target substrate to which graphene is transferred. Here, each reservoir may be filled with a solution for a wet transfer process, and the graphene may be separately located in each separated space in a floating state in the solution.

The present invention relates to an apparatus of manufacturing an aerogel sheet. The apparatus of manufacturing the aerogel sheet includes: a tray device in which a fiber sheet is accommodated; a rotation device including a rotation rod to which the tray device is fixed and a driving member rotating the rotation rod so that the tray device is disposed on an upper and lower portion of the rotation rod; an injection device injecting a silica precursor into the tray device disposed on the upper portion of the rotation rod to impregnate the silica precursor into the fiber sheet; and a surface modification device injecting a coating solution into the tray device disposed on the lower portion of the rotation rod to modify a surface of the fiber sheet in which the silica precursor is impregnated.

A device comprising a rotating means enclosed in a housing and having a horizontally arranged rotating shaft. Containers for cassettes containing samples are mounted on the rotating shaft and are joined in the form of a vertically arranged ring. The device has a means for rotating the rotating shaft at a variable speed and vessels containing processing and infiltrating liquids, said vessels being arranged outside the housing and being connected thereto by pipes for feeding in and discharging said liquids. The device additionally contains a mechanism for orienting the containers for cassettes containing samples, which mechanism is arranged between the ring of containers and the wall of the device, has a separate means for transferring the containers for cassettes containing samples into a horizontal or inclined position and holds same in the horizontal or inclined position.

Disclosed is a method of applying a coating to a glass sleeve with an inner surface and an outer surface, the glass sleeve configured as a part of a solar-receiver tube. Thereby, the coating is solely applied to one of the surfaces of the glass sleeve. Also disclosed is a method of fixing such glass sleeve in an interior of a coating tank, such coating tank and a fixing arrangement for fixing such glass sleeve in an interior of a coating tank.
