Pneumatized inferior turbinate (concha bullosa of inferior turbinate)

Malawi Medical Journal
The nasal cavity structures are prone to different anatomical variations; one of these is concha bullosa, which best known as pneumatization of the nasal turbinate. This pneumatization is a rare phenomenon to in the inferior turbinate. We report the case of an incidental finding of inferior turbinate concha bullosa in a 30- year-old female who ...

Polystyrene/TiO2 Composite Thin Films by Powder Aerosol Deposition: Film Morphology Control Through Powder Processing

Advanced Materials Interfaces, EarlyView.
It's all in the mix! By employing different homogenization strategies for preparing polystyrene/TiO2 polymer‐ceramic composite (PCC) powders, we tune the morphology of PCC films obtained by powder aerosol deposition, ranging from segregated multilayer‐like to finely blended composites.
