• SURFACE AREA: AN EXPLORATORY TOOL

Abstract

Surface area is a ubiquitous term used in the field of mathematics, material and biological sciences. Specific surface area of material is an important physical parameter and  influences many aspects of product performance such as the hiding power of pigments, the activity of catalysts, the taste of food, the potency of drugs and the bioavailability of drugs. A variety of classical and advanced instrumental measurement methods to calculate specific surface area are available in the literature. The review gives glimpse of these methods and focuses mainly on important applications of specific surface area in the pharmaceuticals, catalysis, hydrogen storage and electronics.
