Methanol to acetic acid
At the moment, a majority of industrial undertakings in acetic acid production are dominated by methanol carbonylation and the oxidation of hydrocarbons such as ethylene, acetaldehyde among others. Advances in acetic acid synthesis and catalysis can be grouped into five broad categories.

Structure and Bonding of 5 different materials (Chemistry)
Silicon dioxide is abundantly present in the form of sand. It is hard i.e. very difficult to break into smaller parts and is resistant to abrasion. It is a non conductor of electricity, insoluble in both polar and non polar solvents and has a high melting temperature of around 1700oC (Jim, 2010).

Summary of Molecule bonds, Amino and Nucleic Acids, Proteins
The bond will not be broken until a sufficient transfer of energy occurs. There are several types of chemical bonds that differ in aspects such as the strength of the bond. Strong bonds include covalent (electron sharing) and ionic (positive to negative attraction and vice versa), while some weaker types are dipole-dipole interactions (intermolecular, or between molecules), London dispersion force (weak quantum effect), and hydrogen bonding (covalent bonding of hydrogen to two electrically negative atoms).

Materials Engineering
It refers to the point during the application of stress on a material at which the material fails and thus breaks. From this point, the curve starts going down indicating that a small increment of little strain requires a relatively smaller stress. Fracture refers to the

Determination of conductance of various solutions
From the data obtained it was clear to categorize the solutions in the experiment according to their conductance values. The solutions whose ions dissociate fully in aqueous solution produced the highest conductance while those that dissociated partially gave lower conductance and hence were classified as strong and weak electrolytes respectively.
