Smaller structures with sizes ranging from 0.1 to 100 nm are studied in nanotechnology. The pharmaceutical industry is about to undergo a great change as a result of this specialty. It covers various fields such as biophysics, molecular biology, biotechnology, as well as subfields of medicine such as cardiology, ophthalmology, endocrinology, oncology, and immunology. New drug delivery systems are being developed by pharmacies to overcome the shortcomings of conventional methods. This Seminar ...
CHAPTER ONE 1.0 INTRODUCTION In the past with the necessary of metals it always seems impossible to join two metals together with grooving riveting, this idea leads to alternative of finding a lasting solution to the problem. This brought about the idea of a welding machine with a well laminated core and coil wound together to form a high rated transformer which is immersed in a can of oil. Welding is the most economical and efficient way to join metals permanently. It i...

INTRODUCTION Definition and Explanation of some Terms What is a chemical industry? It is difficult to define chemical industry exactly because of the absolute necessity for chemicals in almost every manufacturing industry. However, chemical industry can be defined as one that consists of all companies engaged in converting raw materials obtained from the environment (air, water, petroleum, minerals, agricultural products etc) into basic chemicals or chemical intermediates as well as the co...
Cellulose is the most abundant, structural, biological organic compound on Earth which is widely used in paper and textile industries. In this project work, the blend of compressive character of Urea-Formaldehyde Resin with addition of Cellulose is tested. Cellulose can be extracted from dried plant by alkaline treatment (mercerization), followed by neutralization with acid; product of which undergoes bleaching to produce pure form of cellulose. Urea Formaldehyde Resin c...
ABSTRACT Acid rain is a mixture of sulfuric acid and nitric acids depending upon the relatively quantities of oxides of sulfur and Nitrogen emissions. Theses emissions are from the exhaust pipe or smokestacks of our vehicles and others like power stations, generators, appliances and so on. Acidification of water bodies causes large scale negative impact on aquatic organism including fishes; acidification has an indirect effect on humans. It has effect on the ecosystem and causes damages to ma...
Abstract Cosmetics are care product applied to the body or face to improve appearance. The concept of beauty and cosmetics is old as mankind and civilization. Assorted beauty and cosmetics product such as skin care product, fragrance, oral hygiene, and nail product, which may contain toxic chemicals that can be harmful to health are used especially by women. The bioaccumulation of this harmful chemicals and metals in the body overtime has been associated with different signs of illness and wh...
The usefulness and benefits of hydrogen as a fuel is of no comparison, as it does not contribute to the environmental hazard i.e air pollution caused by other fuels such as methane and petroleum.The end product of hydrogen in fuel cells and combustion engine is energy and water vapor as its only byproduct.
Carbon black is a generic term for a particular form of elemental carbon manufactured by vapour- phase pyrolysis or partial combustion of hydrocarbons. It is the term for an important family of products that is used principally for the reinforcement of rubber, as a black pigment and because of its electrical, conductive properties It does not occur as a natural product (IARC, 2010) and it is one of the most stable compounds (Pilusa & Muzenda, 2013).
CHAPTER ONE 1.0Introduction Nitric oxide (NO), colourless is a toxic gas that is formed by the oxidation of nitrogen. Though it has few industrial applications, nitric oxide performs important chemical signalling functions in humans and other animals and has various applications in medicine. It is also a serious air pollutant generated by automotive engines and thermal power plants (Abubakar, 2011).
ABSTRACT The use of dye and bleaches on hair have been dated back to early ages, as the process of civilization and advance technology take place, many different dyes are been sold in the market. The side effects of dyes and bleaches on human include burning, discoloration, hair breakage and cancer. This review discussed the different types of dyes, their chemical composition and the detrimental effects associated with the use of dyes and bleaches.
1.0 INTRODUCTIONHair coloring is the practice of changing the hair color. The main reasons for this are cosmetic, to cover gray hair, to change to a color regarded as more fashionable or desirable, to restore the original hair color after it has been discolored by hairdressing processes or sun bleaching. Hair dyes generally contain dyes, modifiers, antioxidants, alkalizers, ammonia and a mixture of other compound used to impart different qualities to hair depending on the hair type, col...

ABSTRACT Polymers are used in various ways and they constitute the bulk of demand in the utilization of basic petrochemicals both in industries and domestic uses. Polymers have posed serious environmental problems because of their undegradability. Polymer degradation is a change in the properties of a polymer or polymer based products under the influence of one or more environmental factors such as heat, light, chemicals such as acids, alkalis and some salts, atmospheric oxygen, microorganism...
ABSTRACT Water plays a very vital role in our daily lives. Human and other forms of life practically depend on water for survival. Water also plays an important role in the World Economy, as it functions as a solvent for a wide variety of chemical substances and facilitates industrial cooling and transportation. Water is an infinite resource; it moves continually through the water cycle and covers about 71 percent of the earth’s surface. However, clean and safe drinking water is becoming sc...
