Black surface plays an important role in solar-thermal conversion systems and space optical systems. Despite the significant efforts in developing a black surface with strong broadband absorption, realizing scalable omnidirectional high absorption ultrablack surfaces remains challenging. Here, we report an ultrablack surface based on a structural black paint (SBP), realized by femtosecond (fs) laser fabrication of high aspect ratio microstructure mold followed by mold transferring on black paint coating.

- The study looked at how tiny droplets from people could spread in an office when two workers used a special ventilation device called a round movable panel (RMP).
- Three different methods of air circulation were tested to see which worked best to keep the air clean.
- It was found that the special device could help reduce the spread of small particles in the air, but sometimes it could also make things worse depending on how much airflow it created.
The micropore surface area and micropore structure of refuse derived fuel (RDF) was changed by compression treatment. Thermogravimetric curves can be obtained at different pyrolysis temperatures, to estimate some of the kinetic parameters of different samples. A number of data collected and analysis was presented in the paper, together with the rules of kinetic parameters and discussion on the influence of the character of RDF's micropore structure.
