Graphene Oxide as an Auxiliary UV Photoprotector for Polypropylene
Polymer Composites, Volume 46, Issue 16, Page 14986-15000, 10 November 2025.Auxiliary UV Protection. ABSTRACT This work presents the preparation and characterization of polypropylene (PP)/graphene oxide (GO) nanocomposites by adding photostabilizing additives to obtain materials with enhanced resistance to photodegradation. The synthesized GO (modified Hummers' method) was characterized using state‐of‐the‐art techniques.

Skeleton‐Based Posture Recognition for Home Care From Virtual Unmanned Aerial Vehicle
Expert Systems, Volume 42, Issue 9, September 2025.ABSTRACT This article presents a novel approach for real‐time posture recognition in monitoring scenarios, utilising a virtual camera simulated on a UAV within virtual environments. Leveraging the MediaPipe Pose library, key points of the body skeleton are extracted, focusing on a subset of 8 key points for computational efficiency.
