at temperatures as low as –40°F at far less cost and with greater accuracy. Relative humidity was once determined by measuring the change in moisture absorption in silk‚ human hair‚ and later‚ nylon and synthetics. Mechanical methods for measuring RH were introduced in the 1940s. Recently‚ polymer-based resistive and capacitive sensors have been developed Sensor Types and Technologies Recent developments in semiconductor technology have made possible humidity sensors that are highly accurate‚

IMPORTANCE OF PLASTIC:- Plastics are a subset of materials known as Polymers. These are composed of large molecules formed by joining many smaller molecules together (monomers). Other kinds of polymers are fibres‚ elastomers‚ surface coating and biopolymers‚ such as cellulose‚ proteins and nucleic acids. Plastics owe their name to their ability to be shaped to form articles of practical value by various conversion and forming processes. These are some peculiar properties of plastics materials‚ which

RECENT DEVELOPMENTS IN NANOPARTICLES. INTRODUCTION Nanotechnology is a multidisciplinary scientific field undergoing explosive development. Nanometer-sized particles offer novel structural‚ optical and electronic properties that are not attainable with individual molecules or bulk solids. Advances in nanomedicine can be made by engineering nanoparticles that are capable of targeted delivery of drugs. This leads toward the concept and possibility of personalized medicine for the potential

the environment of man-made plastic products to the point where they create problems for wildlife and their habitats as well as for human populations. In 1907 the invention of Bakelite brought about a revolution in materials by introducing truly synthetic plastic resins into world commerce. By the end of the 20th century‚ however‚ plastics were found to be persistent polluters of many environmental niches‚ from Mount Everest to the bottom of the sea. Whether being mistaken for food by animals‚ flooding
