Composite materials that traditionally incorporate micron scale reinforcements in a bulk matrix offer opportunities to tailor material properties such as hardness, tensile strength, ductility, density, thermal and electrical conductivity, and wear resistance.

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.

Among various ceramics, one-dimensional (1-D) piezoelectric ceramics have attracted significant scientific attention for use in energy harvesting.

Electronically, it behaves as a wide band gap (3.2 eV) semiconductor and exhibits memristor properties.2 Optically, TiO2 has high opacity with a very high refractive index3 (>2.4), and it exhibits strong absorbance in the UV range.
