Nanoarchitectonics for advanced applications in energy, environment and biology
By applying nanotechnology in the field of materials science, functional materials with advantageous nanoscale features can be generated. This concept can be further advanced by the emerging field of nanoarchitectonics. By using the nanoarchitectonics strategy, functional materials can be constructed by using nanoscale units and the principles of nanotechnology.
The nanoarchitectonics concept was initiated at the beginning of the 21st century, and it can be widely generalized, regardless of the material used or purpose. Thus, nanoarchitectonics approaches should be relevant to a wide range of applications, including materials synthesis, structure organization, catalysts, sensors, and energy, environmental as well as biomedical applications.
This thematic issue will focus on the application of nanoarchitectonics to critical and essential areas for the society, such as energy, ecology, and biology.
