摘要:
A surface coating layer (120), in contact with a surface of a base material (100) of a heat exchanger, comprises a plurality of composite layers comprising a first layer (120a) contacting a surface of the base material (100), the first layer (120a) comprising a first composite comprising a first matrix (50a) and a first nanobody (50b), and a second layer (120b) contacting a surface of the first layer (120a) and having an interface with the air, the second layer comprising a second composite comprising a second matrix (50a) and a second nanobody (50b), wherein the first layer (120a) and the second layer (120b) each include a different amount by volume of the first nanobody and the second nanobody, respectively.

摘要:
A photoelectrochemical device and method using carbon nanotubes (206) comprise highly electrically conductive carbon nanotubes formed at an interface between a transparent electrode (201) and a metal oxide layer (207). According to the photoelectrochemical device and method, the interface resistance, which is caused due to an incomplete contact at the interface, is lowered and thus the electron mobility is improved, leading to high power conversion efficiency.
