Syllabus
Microscopic view of thermodynamics: Entropy and probability, Boltzman’s paradox, distribution of molecular states, configuration and weights, molecular partition function, internal energy and statistical entropy. Solid state chemistry: arrangements of atoms in 3D, close packing vs simple packing of spheres, introduction of Miller indices (planes and directions) in cubic and hexagonal systems, crystal parameters and seven crystal systems, Bravais lattices (14 types), voids (tetrahedral, octahedral) in hexagonal and cubic systems, radius ratio rules, elementary concepts of X-ray diffractions, Bragg’s equation, interplaner spacings, powder X-ray diffraction patterns by Debye-Scherrer method, difference between powder and single crystal diffraction patterns. Colloids: colloidal state, kinetic stability, electrical double layer, concept of electrokinetic potential and applications, optical properties of colloids (scattering). Liquid surface: surface tension and interfacial tension, phenomena at curved surfaces (Kelvin equation and its significance), capillary rise, bubbles and sessile drops, contact angles and wetting, concept of surfactants, micelles and self assembly, liquid crystals, emulsion and micro emulsion. Adsorption: solid-gas interface, physisorption vs chemisorptions, Adsorption isotherm (Langmuir, Feundlich & BET), mechanisms of heterogeneous catalysis. Surface analysis: elementary concepts of interaction of electrons with surface (secondary electrons, Auger effect, photoelectron spectroscopy, low energy electron diffraction), atomic force microscopy (introductory concept).
