CHAPTER 1: CLASSIFICATION OF MATERIALS
COMPOSITION Composition tells what chemicals are in a sample. The most specific description will reveal the chemical elements that are present in the sample. Chemists determined that matter is composed of combinations of about 100 elements. The simplest pieces chemists can make are atoms. Atoms of the same element are identical (have
Chemical Overview of Wood
Chemical Composition of Wood Wood is essentially composed of cellulose, hemicelluloses, lignin, and extractives. Table 1 presents major chemical compositions of some wood species. Each of these components contributes to fiber properties, which ultimately impact product properties.

Chemical composition of common bile duct stones
The common bile duct stones obtained from 148 patients were analysed chemically for cholesterol, calcium and bilirubin. When stones were present in both the common bile duct and gallbladder at the time of surgery, the common duct stones were similar in chemical composition to gallbladder stones in the majority of cases and were predominantly cholesteroltype stones.
