The field of optics that deals with non – linear behavior of optical materials is known as non- linear optics. The material for which the optical properties depends on the intensity of light and behave non – linearly...
Though nano-particles are very small, they are the important materials to built the future world. They have applications almost in all fields as follows Nanomaterials in Energy Production Generating steam from sunlight: The...
There are two general approaches to the synthesis of nanomaterials, they are (a) The top-down approach (b) The bottom-up approach (a) The top-down approach It is a approach in which smaller objects are made by carving or...
Nanomaterials have the structural features in between of those of atoms or molecules and the bulk materials. The properties of nanomaterials change as their size approaches the nanoscale. Thermal properties : Nanomaterials have...
The term nano originated from the Greek nanos which means “dwarf”. It is one billionth of a meter. Therefore, whenever we think about nonoscience or nanomaterials very small objects come to the mind. A nanometre...
Ni-Ti alloy was developed in 1962 by Naval Ordnance Laboratory, White Oak, Maryland, USA and is commercialized under the name nitinol (nickel-titanium Naval Ordance Laboratory). Ni-Ti alloy shows shape memory effect when...
Shape memory effect It is the phenomenon in which the shape memory alloy apparently deforms at lower temperature and returns to its original shape (former shape) when heated at higher temperature. Let us consider a shape memory...
Definition : Shape memory alloys are special type of alloys that have the ability to return to a original defined shape when heated. Shape memory alloys are also called as smart materials (or) intelligent materials (or) active...
Since the atoms in the metallic glasses are disordered, they have some peculiar properties as follows. a) Structural properties Metallic glass have tetrahedral closely packed (TCP) structure rather than hexagonal closely packed...
