Synthesis and Characterization of TiO2 1% SiO2 of Crystal and its Bacterial Applications
Abstract: Three-dimensional (3D) TiO2 Anatase and Rutile structures have attracted much attention due to their optical properties. However, the large band gap of (3.2 eV) results in the fact that anatase TiO2 can act as photo catalyst and be excited by UV light, which only accounts for 3–5% of the solar energy. On considering that nobel metallatic nanomaterials can harvest visible light, in this paper, TiO2 and SiO2 nanocrystals with rod …

Correlating the Damage Behaviour of Polymer Composites with the Potential Energy of the Impactor
Abstract: Design of structures using composites requires comprehensive evaluation and characterization of mechanical properties in both undamaged and damaged state. Composite laminates undergo combinations of mechanical loading resulting into microdamage accumulation in the plies. The first mode of damage is usually intralaminar cracking with the crack plane transverse to the middle plane of the laminate, spanning the whole width of the laminate. The density of cracks in a ply depends on …
