1. INTRODUCTION
Nano materials have inmost a huge concentration in the last two decades because of their unique properties that find potential applications in many fields of science and technology. It has grown explosively in the last decade, because of the increasing availability of methods, synthesis of nanomaterials as well as tools of characterization and manipulation. Nanotechnology makes us to believe that we would have the ability to create anything that we could precisely define.
Synthesis of nanomaterials is another key issue. General approaches in synthesizing nanomaterials involve vapour, liquid or solid state routes or their intelligent combinations. Size effects are an essential aspect of nanomaterials. Size effects are of two types: one is concerned with specific size effects and other with size scaling applicable to relatively larger nanostructures. Synthesis of nanomaterials includes control of size, shape and structure. Ultrahigh performance cooling is one of the important needs of Automobile industries. Hence the recent advancement for efficient cooling is Nanofluids.
Viscosity as one of the most important factors which are used for correct selection of the required oil in a lubricating system and also flash point and pour point are the properties which are related to the quality of oil functionality in different work conditions. The concentration of nanoparticles has a great effect on the functionality of nanolubricants. The nanofluid is not a simple liquid-solid mixture; the most important criterion of nanofluid is agglomerate-free stable suspension for long durations without causing any chemical changes in the base fluid. Nanometer sized particles prevent particles from agglomeration and the settling of pa...

Nano-thermal analysis methods are also known as micro-thermal procedures and they use the principle of characterizing highly localized materials on a micrometer. The characterization is then changed from a micrometer scale to a sub-micrometer scale with the temperature being regulated to the specified units. The application of nano-thermal analysis methods started towards the end of the 20th century. Although it has been applied in several other fields including microelectronics, its application in pharmaceuticals has not been that popular.

Nanotechnology is the manipulation of structures at nano levels. It uses incredibly small materials, devices, and systems to manipulate matter. These structures are measured in nanometers, or one billionth of a meter, and can be used by themselves or as part of larg...
Thin film coatings of ceramic materials are widely used to safeguard materials against corrosion, wear resistance, and thermal conductivity [1, 2]. The objective of this work is to increase the thermal resistivity and thereby improve the mechanical properties of the materials. In this work thin film of Ceria stabilized Zirconia was formed and is applied on the area where the heat transfer occurs the most and is used to reduce its effect of temperature. These coatings are used to protect parts from big and prolonged heat loads by utilizing thermally insulated materials which can undergo a significant temperature difference between the initial material and the coating surface [3]. Many new materials have been developed, but steel remains the principal construction material for automobiles appliances, and industrial machinery. Since steels are vulnerable to aggressive chemical environments or atmospheric oxidation, metal coating is necessary to provide various degrees of protection through hot-dipped and electroplating process to tough polymers and flame-sprayed ceramics. In general corrosive atmospheres contain more than one active material, and the coating must resist dissemination by a combination of oxidizers, solvents, or both. Thus, the best hurdle is one that resists corrosion [4]. The obligatory thin films have been attained by using spray pyrolysis coating method. Spray pyrolysis technique involves spraying of a solution containing soluble salts of the desired compound on to preheated substrates, where the constituents react to form a chemical compound [8, 9]. Both, dense and porous structures can be deposited by spray pyrolysis which can also be achieved on large substrates by scaling up the equipment. It has capability to...
