OCY1702 INTERFACE CHEMISTRY AND ENGINEERING L T P C
3 0 0 3

OBJECTIVES:

 To acquire knowledge on basic principles of interface chemistry, basic concepts of colloidal
particles, and applications of surfactants, emulsions and gels.
 To acquire knowledge on biosensors, corrosion and its surface modification techniques.

UNIT I SURFACES AND INTERFACES 9
Types of interfaces- liquid surfaces- curved interfaces-young -laplace and kelvin equations; capillary
condensation; surface tension; solid-liquid interfaces-contact angle and wetting-solid surfaces-
external and internal surfaces-homogeneous and heterogeneous surfaces. Solid-gas interfaces-
types of adsorption-adsorption isotherms – langmuir,and BET.

UNIT II COLLOIDAL SCIENCE 9
Introduction to colloidal material, surface properties, origin of colloidal particles, preparation &
characterization of colloidal particles. Applications of super hydrophilic & hydrophobic
surfaces.

UNIT III SURFACTANT TECHNOLOGY 9
Introduction to surface active agents. Types of surfactants- Micelle-Emulsions-Micro emulsions –
Gels - Applications of surface chemistry in biomedical industry -Ointment and absorption bases.

UNIT IV CORROSION AND SURFACE MODIFICATION 9
Basic principles of corrosion -Chemical and electrochemical corrosions-Factors influencing
corrosion, Surface Modification - Classifications of surface coatings- Electroplating-
Electrophoretic deposition- Advanced ceramic coating in automobile and biomedical industries

UNIT V BIOSENSORS 9
Basic principles of biosensor- Classification-characterization-properties. Application of Biosensors-
Food Analysis, Bioprocess Control and Environmental Monitoring.

TOTAL HOURS : 45
