摘要:
According to the present invention, there are provided processes for preparing a porous composite material comprising a metal and a two-dimensional nanomaterial. In one aspect, the processes comprise the steps of: providing a powder comprising metal particles; heating the powder such that the metal particles fuse to form a porous scaffold; and forming a two-dimensional nanomaterial on a surface of the porous scaffold by chemical vapour deposition (CVD). Also provided are materials obtainable by the present processes, and products comprising said materials.
摘要:
An etching solution for removing a metallic layer from a substrate contains a hydrogenated compound that dissolves the metal itself while evolving hydrogen and a nitro-substituted organic compound. The solution is characterized by the fact that the selected nitro-substituted organic compound is a compound having an easily hydrogenizable nitro group.

A heat storage apparatus according to the present disclosure includes a heat storage material and a member. The heat storage material forms a clathrate hydrate by cooling. The member has a surface with a plurality of holes. In the case that the lattice constant of the clathrate hydrate is denoted by L and the outside diameter of a cage included in the clathrate hydrate is denoted by D, the plurality of holes are spaced at intervals of 1 L to 10L, and each of the plurality of holes has a hole diameter of 1D to 20D.
摘要:
Disclosed are cleaning solvents and cleaning methods for metallic compounds deposited on the equipment that supplies organometallic compounds to the manufacturing tool in the photovoltaic industry or the semiconductor industry. The cleaning solvents and the cleaning methods disclosed not only selectively remove the metallic compound without corroding the equipment, but also improve the ordinary cleaning process. Moreover, the cleaning solvents and the cleaning methods disclosed improve maintenance costs for the supply system because the equipment may be cleaned without being detached from the supply system.
摘要:
Une solution d'attaque qui sert à enlever une couche métallique déposée sur un substrat contient un composé hydrogéné qui dissout le métal proprement dit tout en dégageant de l'hydrogène et un composé organique à substitution nitro. La solution se caractérise par le fait que l'on sélectionne comme composé organique à substitution nitro un composé dont le groupe nitro est facile à hydrogéner.
