Optimizing pollutant removal ability of GO/ZnO nanocomposites via controlled GO treatment and ZnO NPs content Mater. Sci. Eng. B (IF 3.6) Pub Date : 2024-01-25 Abdullah S. Alshammari, Muhammad M. Alabdi, Alaa Abd Alfatah, Mansour Mohamed
Nanocomposites are promising materials for many applications including environmental ones. Herein graphene oxide / zinc oxide nanocomposites were prepared using simple chemical methods and used to purify polluted water samples. Highly dispersed and uniformly decorated GO nano-sheets with ZnO nanoparticles were synthesized and were utilized for water treatment applications. Two factors were investigated:

Electrospun PVDF/Si-HBP of 3rd gen based nanoweb as flexible and self-powered TENG for real-time energy harvesting Mater. Sci. Eng. B (IF 3.6) Pub Date : 2024-01-28 B. Indumathy, A. Anand Prabu
Triboelectric nanogenerators (TENGs) excel in converting mechanical energy into electrical energy and are recognized as the optimal solution for energizing wearable electronics. In this study, we fabricated TENGs based on electrospun polyvinylidene difluoride (PVDF)/silane-based hyperbranched polyester of 3rd generation (Si.HBP-G3) nanoweb blends (0–40 wt-% of Si-HBP-G3 w.r.t. PVDF content). In the
