Electroplating is an electro deposition process for producing a dense, uniform, and adherent coating, usually of metal or alloys, upon a surface by the act of electric current. Electroplating is primarily used to change the surface properties of an object e. Electrochemical deposition is generally used for the growth of metals and conducting metal oxides because of the following advantages: i the thickness and morphology of the nanostructure can be precisely controlled by adjusting the electrochemical parameters, ii relatively uniform and compact deposits can be synthesized in template-based structures, iii higher deposition rates are obtained, and iv the equipment is inexpensive due to the non-requirements of either a high vacuum or a high reaction temperature. An electrochemical process where metal ions are transferred from a solution and are deposited as a thin layer onto surface of a cathode.

Account Options Sign in. Epoxy is a term used to denote both the basic components and the cured end products of epoxy resins, as well as a colloquial name for the epoxide functional group. Epoxy resin are a class of thermoset materials used extensively in structural and specialty composite applications because they offer a unique combination of properties that are unattainable with other thermoset resins.
Epoxies are monomers or prepolymers that further reacts with curing agents to yield high performance thermosetting plastics.
They have gained wide acceptance in protecting coatings, electrical and structural applications because of their exceptional combination of properties such as toughness, adhesion, chemical resistance and superior electrical properties. Epoxy resins are characterized by the presence of a three membered cycle ether group commonly referred to as an epoxy group 1,2-epoxide, or oxirane.
The most widely used epoxy resins are diglycidyl ethers of bisphenol-A derived from bisphenol-A and epichlorohydrin. The market of epoxy resins are growing day by day. Today the total business of this product is more than crores. A standard 1. Traditionally, the markets for epoxy resins have been driven by demand generated primarily in areas of adhesives, building and civil construction, electrical insulation, printed circuit boards, and protective coatings for consumer durables, amongst others.
The major contents of the book are synthesis and characteristics of epoxy resin, manufacture of epoxy resins, epoxide curing reactions, the dynamic mechanical properties of epoxy resins, physical and chemical properties of epoxy resins, epoxy resin adhesives, epoxy resin coatings, epoxy coating give into water, electrical and electronic applications, analysis of epoxides and epoxy resins and the toxicology of epoxy resins.
It will be a standard reference book for professionals and entrepreneurs. Those who are interested in this field can find the complete information from manufacture to final uses of epoxy resin.
This presentation will be very helpful to new entrepreneurs, technocrats, research scholars, libraries and existing units.

Medieval Methods for Making Fabric From Wool
A solvent is usually a liquid but can also be a solid or a gas. Solvents find various applications in chemical, pharmaceutical, oil, and gas industries, including in chemical syntheses and purification processes. Thinners are defined as chemical compounds that are introduced into the paint prior to application, in order to modify the viscosity and other properties related to the rate of curing that may affect the functionality and aesthetics of the final layer painting. Paint thinner, a solvent used in painting and decorating, for thinning oil-based paint and cleaning brushes.SEE VIDEO BY TOPIC: Italian Industry Special: The Fabric Mill
In the Middle Ages , wool was turned into cloth in the thriving wool production trade, in home-based cottage industry, and in private households for family use. Methods could vary depending on the wherewithal of the producer, but the basic processes of spinning, weaving, and finishing cloth were essentially the same. Wool is usually sheared from sheep all at once, resulting in a large fleece. Occasionally, the skin of a slaughtered sheep was utilized for its wool; but the product obtained, which was called "pulled" wool, was an inferior grade to that shorn from live sheep. If the wool was intended for trade as opposed to local use , it was bound up with similar fleeces and sold or traded off until it reached its final destination in a cloth-manufacturing town. It was there that processing began. The first thing done to a fleece was to separate its wool into its various grades by coarseness because different types of wool were destined for different end products and required specialized methods of processing. Also, some types of wool had specific uses in the manufacturing process itself.

As with many discoveries of early man, anthropologists believe the use of wool came out of the challenge to survive. In seeking means of protection and warmth, humans in the Neolithic Age wore animal pelts as clothing.
