Nanomaterials has become one of the most prominent subjects in diverse fields of applications. Nanomaterials have emerged as one of the most promising things in different fields ranging from biomedical to pharmaceutical. The word nanomaterial originated from the Latin word 'Nanos' which means very small. Hence nanomaterials are particles of extremely small dimensions in the range of nanoscale. Nanotechnology has just added to the number of creative items in different building disciplines due to their remarkable and compensating substance, physical, and mechanical properties. One famous utilization of nanomaterials is nanotubes. Carbon nanotubes (CNT) are one of an illuminative model for the capability of nanotechnology. The elasticity of high carbon steel is around 1.2 GPa however the rigidity of carbon nanotubes (CNT) is 63 GPa. Likewise they are known to be perhaps the most grounded material having been created by nanotechnology up until this point. 1.1) WHAT ARE NANOMATERIALS? Nanomaterials can be seen as the building blocks or cornerstones of nanotechnology. Nanomaterials are defined as substances having at least one dimension in nanoscale i.e. less than approximately 100 nanometers. These materials play an important role because of the presence of unique magnetic, electrical ,optical and many other such properties at such a small scale. Many properties are seen to emerge at nanoscale range. Hence , Nanomaterials deal with substances in the range of 1-100 nm. 1.2) HISTORY The history of Nanomaterials started all after the big bang when formation of nanostructures occurred in the early meteorites. Many different nanostructures were identified after that such as sea shells. The Scientific approach of nanomaterials started however was developed much later. Michael Faraday's study on colloidal gold particles is one of such scientific reports known. Besides this , It has been more than 70 years of investigation on nanostructured catalysts. Today nanophase building extends in a quickly developing number of basic and practical materials, both inorganic and natural, permitting control of mechanical, reactant, electric, attractive, optical and electronic capacities. The creation of nanophase or group amassed materials is generally founded on the formation of isolated little bunches which at that point are melded into a mass like material or on their installation into minimized fluid or strong network materials.

Short Notes for Understanding the Basics of Nano Technology

International Journal of Science and Engineering Applications, 2014

In this paper, the basic terms and definitions of nano technology was discussed. The characteristics, advantages and disadvantages of nano technology were discussed. Applications of nano technology were also mentioned. This paper would be useful to young engineers to study the fundamentals of nano particles. Two approaches used for nano technology were also elaborated.

Advanced Nanomeasuring Techniques for Surface Characterization

ISRN Optics, 2012

Advanced precise and accurate nanomeasurement techniques play an important role to improve the function and quality of surface characterization. There are two basic approaches, the hard measuring techniques and the soft computing measuring techniques. The advanced soft measuring techniques include coordinate measuring machines, roundness testing facilities, surface roughness, interferometric methods, confocal optical microscopy, scanning probe microscopy, and computed tomography at the level of nanometer scale. On the other hand, a new technical committee in ISO is established to address characterization issues posed by the areal surface texture and measurement methods. This paper reviews the major advanced soft metrology techniques obtained by optical, tactile, and other means using instruments, classification schemes of them, and their applications in the engineering surfaces. Furthermore, future trends under development in this area are presented and discussed to display proposed solutions for the important issues that need to be addressed scientifically.
