two main industries that use it will be the removal of nitrogen oxides in industrial exhaust gas and for the catalytic cracking of heavy oil. Finally this catalyst is being characterized using three methods which are the infrared spectra‚ X-ray diffraction as well as the TGA and DTA methods. 2.0 Introduction Catalyst is a substance that causes the change in rate of a chemical reaction. This reaction is known as catalysis and unlike other reagents that take part in a chemical reaction

Since light has a dual nature‚ it can travel both like a particle and like that of a wave. As the light travels from a person’s eyes‚ images can be form as it is reflected by the mirror. Properties such as reflection‚ refraction‚ interference and diffraction is identified in this study. Mirrors being specifically used as an optical instrument‚ gathers light and forms images‚ and is therefore the most common apparatus used in observing the porperties light particels and waves have. Similarly‚ we see

Physics Formulas: Mechanics Mechanics is the oldest branch of physics. Mechanics deals with all kinds and complexities of motion. It includes various techniques‚ which can simplify the solution of a mechanical problem. Here are some of the often required physics formulas falling in mechanics domain. Motion in One Dimension The physics formulas for motion in one dimension (Also called Kinematical equations of motion) are as follows. (Here ’u’ is initial velocity‚ ’v’ is final velocity‚ ’a’ is

The natural plant exudate gum tragacanth is obtained from the stem of the bush like plant “goat’s-horn”‚ Astragalus species. Gum tragacanth has been used commercially for well over 2000 years and is currently widely used as a thickener and emulsifier in emulsion systems in different pharmaceutical‚ food‚ cosmetic and diverse industrial uses. In addition‚ it is on the list of stabilizers that are permitted by Food and Agriculture Organization/ World Health Organization that could be used during the

4002DFPHAR PHYSICAL PHARMACEUTICS Particle Size Analysis The study of particle dimensions is important in many areas of manufacture and technology. Many solid materials are at some point powder or granular in form e.g. foods (grain‚ flour‚ sugar)‚ ceramics and building materials (sand and cement). In pharmaceutical development and manufacture‚ particle size greatly influences physical properties such as powder flow‚ powder mixing‚ drug dissolution‚ deposition from inhaler devices and the stability
