Thiwaporn Chumphon, Ariya Khamnuandet, Ekachai Wimolmala, Worawat Poltabtim et autres

This study valorized silicone waste powder (SWP) reclaimed from discarded silicone molds as a silica-rich secondary filler in ethylene–propylene–diene monomer (EPDM) composites containing nano-sized bismuth oxide (nano-Bi 2 O 3 ) for lead-free diagnostic X-ray shielding applications. To enhance filler–matrix compatibility, SWP …

Gamma-induced modification of pomegranate extract-capped silver nanoparticles: Physicochemical and antibacterial properties

Thanatchaporn Sakee, Paphitchaya Thepko, Chalisa Moonlek, Donruedee Toyen et autres

In this study, silver nanoparticles (AgNPs) were synthesized using pomegranate ( Punica granatum ) peel extract, followed by post-synthesis gamma irradiation at doses of 0 – 60 kGy to investigate gamma-induced modifications of their physicochemical and antibacterial properties. The UV–Vis results indicated …

Synergistic enhancement of mechanical and X-ray shielding properties in natural rubber latex gloves containing Bi2O3 nanoparticles through multilayer design

Ariya Khamnuandet, Ekachai Wimolmala, Worawat Poltabtim, Pattra Lertsarawut et autres

This study evaluated the effectiveness of multilayer design for simultaneous enhancement of the X-ray shielding and mechanical properties with heavy-metal fillers by incorporating nano-Bi 2 O 3 within a middle layer while having pristine NRL as the outer layers, with each layer …
