Electrospun polysulfone/poly(lactic acid) nanoporous fibrous mats for oil removal from water [PDF]

Adsorption Science & Technology, 2019
The study of oil sorbents with high oil sorption capacity is of great significance for oil–water separation, especially for oil spillage on seawater. In this work, we report polysulfone, poly(lactic acid), and polysulfone/poly(lactic acid) nanoporous ...

Abscess formation caused by a foreign body reaction to a poly-d, l-lactic acid (PDLLA) absorbable plate for zygomaticomaxillary complex (ZMC) fracture

Bulletin of the National Research Centre, 2022
Background The poly-d, l-lactic acid absorbable plate does not contain poly l-lactic acid, which is the main factor in foreign body reactions; therefore, with use of this plate, a foreign body reaction is unlikely.
