The Hidden Diptera Diversity in Aristolochia Trap‐Flowers: Revealing the Identity of Pollinators Through Taxonomic Knowledge

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Although Diptera is one of the most diverse insect orders with a high potential for pollinating plants, it remains poorly studied and neglected. This is partly due to limited taxonomic efforts in species identification. For instance, despite being primary pollinators of trap flowers, species‐level identification in these systems remains scarce.

Temperature Influence on the Aging of Titanium Surfaces Treated With Cold Atmospheric Plasma: Impact on Physicochemical Properties and Biological Responses

open access: yesJournal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 113, Issue 10, October 2025.
ABSTRACT Titanium surfaces treated with cold atmospheric plasma exhibit enhanced wettability, cell adhesion, and surface energy; however, these beneficial effects tend to diminish over time due to aging‐related changes caused by surface recontamination and the gradual loss of reactive species.
