The Basics of Raman Spectroscopy Raman spectroscopy is a powerful analytical technique used to study molecular vibrations within a sample. The principle of Raman spectroscopy lies in the interaction of light with molecules, where...
1. What are metallic glasses? Metallic glasses are amorphous metals [Glassy metals]. It is a non-crystalline alloys with molten liquid state. It has the short range of atomic order. Metallic glasses share the properties of both...
It is a method in which the reaction or thermal decomposition of gas phase species at higher temperature (500 – 1000°C) and then nanoparticles deposition on a substrate takes place. In chemical vapour deposition method...
METALLIC GLASSES Metallic glasses or Glassy metals are non – crystalline (amorphous) alloys with an atomic configuration similar to molten liquid. It has the short range of atomic order. Metallic glasses share the...
1. Hysteresis Hysteresis of a SMA is defined as the difference between the temperature at which the material is 50% transformed to austenite when heating and 50% transformed to martensite when cooling. When the temperature is...
Materials have always played a significant and defining role in human development, from the Stone Age to the material world of today. Materials are central to our prosperity and new materials hold the key to our future...
Laser ablation or deposition was utilized for the first time in the 1960’s, after the first laser (ruby laser) was invented. Then the pulsed laser deposition (PLD) technique has been more rapid and the amount of research...
1. What are Magnetic Materials ? The materials which can be made to behave like a magnet and which are easily magnetized by a magnetic field are called as magnetic materials. 2. How the Magnetism arises in a material? The...
The dielectric characteristics of a material are determined by the dielectric constant or relative permittivity of the material. It is defined as the ratio of the permittivity of the medium to the permittivity of the free...
