George Goble was distinguished for his world-record time igniting a barbecue grill - three seconds, using charcoal and liquid oxygen. Frustrated by the 40 minutes it normally took to get the grill going, Goble, a computer engineer, and some of his friends experimented with alternative for..

Traditionally, chemistry has been divided into three branches - organic, inorganic and physical chemistry. Organic chemistry is the study of compounds of carbon. Inorganic chemistry is the study of compounds of all other elements and a few compounds of ..

The division into orgnic and inorganic chemistry is a fundamental division in chemistry. Carbon compounds have necessitated a seperate branch because of the innumerable number and typical properties of carbon compounds. The number of carbon compounds of all the other elem..

We begin with some inportant definations in surface chemistry..

Chemistry is intimately connected with the development of technology. The manufacture of metals, steel, glass, plastics, paper, cement, textiles, dyes, drugs and so on are directly associated with chemistry. The wonder drugs penicillin and streptomycin, anaesthetics, disi..

This unit deals with some important features of surface chemistry such as adsorption, catalysis, colloids, emulsions etc. The term surface or interface as interpreted in surface chemistry refers to a region where two phases meet. Most of the physical and chemical processe..

A recent attempt for the prevention of environmental pollution is the introduction of Green chemistry. This new branch of chemistry deals with processes and products that reduce or eliminate the use and generation of hazardous substances. Concentration on this line of act..

The study of the boundary separating two bulk phases is called surface chemistry. This boundary is also known as boundary surface or interface. It is expressed either by a hyphen or a straight vertical line. viz. solid-liquid or solid/liquid indicates the interface between two phases so..

Three important phenomena of environmental chemistry which have been studied are "as under : (1) Acid rain, (2) Ozone depletion (3) Green house effect and Global warming...
