Definition of Coatings

Coating is the process whereby one material is used to continuously cover another surface. According to Dewo et al. (2015), coating is a surface modification approach that involves the addition of a new material onto the surface of a substance or element that is at risk of corrosion.

Formula: Rusting of Iron.

iron + oxygen + water ==> hydrated iron(III) oxide (RUST) 4Fe(s) + 3O2(g) + xH2O(l) ==> 2Fe2O3.xH2O(s)

Different Types of Coatings

The process of coating utilizes multiple films of coatings as primers and top layers. The purpose of each layer is particular; however, the layers often interact with one another (Özçam et ...

The periodic table of elements, by far, stands among the most notable discoveries in the history of chemistry. Nowadays, probably everyone who has ever heard about chemistry heard about the periodic table of elements. Its implications on the scientific world are so enormous that it has even leaked out to the general public and have become associated with the chemistry itself. This is not surprising considering the scientific strength of this instrument. Using the periodic table, many characteristic properties of the elements can be predicted and many phenomena can be explained. This discovery put so much scientific knowledge together, ...

Abstract

Color and texture are important attributes related to vegetable quality. The objective of this study was to determine the changes in quality characteristics, caused by cooking time, and pH (alkali and acid addition) in some vegetables. Four different vegetables — carrots, spinach, red cabbage and cauliflower — were analyzed for changes in color and texture associated to time of boiling, the effect of alkali (baking soda), and the effect of acid (vinegar and cream of tartar). Samples of each vegetable were prepared and treated for five minutes. Color change was measured visually and using the L*a*b* technique. Color and ...

Research paper about Lithium

Introduction Metal minerals are critical for the economic development and technological advancement. In the world, many minerals play an important part in easing and improving the development of new and advanced materials. Lithium mineral is an example of the mineral found in some various part of the world and is use in multiple applications in industries. This research paper majorly focuses on lithium production and manufacturing. It gives the brief history of mining and production of lithium, the countries, and companies that are well recognized for the mineral production. It also gives the industrial application of lithium. Furthermore, the ...

Abstract

The following summary discusses the cooling techniques of atomic vapor in several different ways. Additionally, it tends to relate the evolution of experiments that are used in studying shallow layered fluids. Starting with the atomic condensates, the method is known as trapping. However, it exists in many ways from the laser system to the Bose-Einstein methods. The methods of cooling are different due to the evolutionary progress made by science. The use of laser beams includes the study of light forces on atoms which lead to either an absorption or emission of a photon. While the contraction of matter ...

Abstract

The purpose of our experiment was to visualize the effect of light intensity on oxygen production. In the capacity of a test subject we used algal cultures. For these researches we used the Winkler method of titration. Our experiment results showed that there is an effect of light intensity on oxygen production. Our research has a great significance for agriculture, biochemistry and biophysics.

Introduction

Photosynthesis is the metabolic process by which plants trap solar energy, convert it to chemical energy, and store it in the bonds of organic nutrient molecules, such as glucose. Nearly all types of plants and algae, as well ...
