Ultrafine particles: A review about their health
2022.5.15 Ultrafine particles (UFP) impact the human body differently from PM 2.5 or PM 10 fractions. Therefore, scientists cannot apply the same approach to assess the effects of UFP and PM on human health. This work summarizes the health effects, generation, and measurement of ultrafine particles in indoor environments through a literature review.

Highly Permeable Polymer Membranes Containing Directed
The hierarchical structure in the TFNC membrane (Figure 1) is suitable only for high flux UF applications because the mean pore size (about 20 nm) in the barrier layer is confined by the diameter of ultrafine cellulose nanofibers (about 5 nm) involved. The top layer structure, however, can be used as a scaffold for further fabrication of NF, RO, or FO membranes.
