Descrizione generale

Zirconium(IV) oxide (ZrO2) which is also known as zirconia is a ceramic nanoparticle that can be used as a nano-filler. It can be incorporated in a variety of polymer and metal composites to improve the thermo-mechanical properties of the base material.

Applicazioni

ZrO2 can be used as a filler material on PMMA which can further be used as a high strength denture base material. It can also be used as a composite based metallic coating that can improve the overall mechanical properties of the substrate.

Materials for Clean H2 Production from Bioethanol Reforming

Hydrogen is one of the most important resources in providing food, fuel, and chemical products for our everyday life. Sustainable catalytic hydrogen production from bioethanol has gained significant attention in recent years due to globally diminishing fossil fuel supplies, which have necessitated the search for new chemical feedstocks.
