This research develops antibacterial nanostructured surfaces inspired by natural materials such as cicada wings. The engineered surfaces physically rupture bacteria using nanoscale needle-like structures, avoiding traditional antibiotics and reducing the likelihood of antibiotic resistance. The technology could improve infection control in medical devices, implants, and hospital environments.

Plastic is indispensable yet environmentally damaging, especially when recycling increases tool wear in manufacturing. This research develops optimized PVD hard coatings that protect production tools without hindering recyclability. By extending tool life and improving efficiency, it supports a more sustainable, circular plastic economy where materials can be reused with less waste.
