China's rapid urbanization and industrialization process has triggered serious air pollution. As a main air pollutant, PM is affected not only by meteorological conditions, but also by land use in urban area. The impacts of urban landscape on PM become more complicated from a three-dimensional (3D) and land function zone point of view.

With rapid urbanization and industrialization, more attention has been paid to atmosphere quality in China. PM, an important atmospheric pollutant, has attracted widespread public attention. Urban greenspace as a semi-natural surface landscape can affect the concentration and distribution of PM.

The permeability of nanoporous materials is low, which affects the fluid transport behavior inside the nanopores and thus also affects the performance of technologies based on such materials. For example, during the development of shale gas resources, the permeability of the shale matrix is normally lower than 10 mD and has an important influence on rock parameters.

However, the pumps for the transpiration cooling system make the system more complex and increase the load, which is a huge challenge for practical applications. A biomimetic self-pumping transpiration cooling system was developed inspired by the process of trees transpiration that has no pumps.
