摘要:
The present invention can provide a hotel reservation system that searches for vacant rooms at lower prices even after making a reservation. A method of hotel reservation that is performed by a server, comprises steps of: obtaining identification information corresponding to vacant rooms of hotels from external servers; obtaining reservation information of a vacant room from a user terminal; transmitting to the user terminal whether a reservation is confirmed; searching for a first vacant room available within a predetermined period from a check-in date until before the check-in date; and providing a reservation change notification through the user terminal if determining the vacant room with the lower price than that of the reserved vacant room by comparing a price of the reserved vacant room and a price of the first vacant room that is available within the predetermined period.
摘要:
A process for depositing a plurality of layers of iridium on a substrate includes: contacting the substrate with an electrolyte composition including: iridium cations protons; biasing the substrate at a first potential; forming iridium on the substrate at the first potential of the substrate; disposing hydrogen on the substrate; self-terminating the forming of iridium on the substrate in response to increasing a coverage of hydrogen on the substrate; oxidizing hydrogen on the substrate by changing a potential of the substrate from the first potential to a second potential; and changing the potential of the substrate from the second potential to a third potential for forming additional iridium on the substrate to deposit a plurality of layers of iridium on the substrate, such that forming the additional iridium on the substrate occurs at the third potential in response to oxidizing the hydrogen on the substrate at the second potential.

The present invention relates to a method for forming graphene at a low temperature, to a method for direct transfer of graphene using same, and to a graphene sheet. The method for forming graphene at a low temperature comprises supplying a carbon-source-containing gas to a metal catalyst layer for graphene growth formed on a substrate, and forming graphene at a low temperature of 500° C. or less by means of inductively coupled plasma-chemical vapor deposition (ICP-CVD).
