Learning outcomes
This course is intended to provide (engineering students) with a good comprehension of the principles of chemistry and shows how they apply in describing the behaviour of the solid state. A relationship between electronic structure, chemical bonding, and crystal structure is developed.
Course contents
Amorphous and crystalline solids. Symmetry;
the main symmetry elements. Lattices; unit cell; Bravais lattices.
Miller indices for planes and lattice
directions.
Review on packing of atoms, close-packed
structures. ionic crystals and their main structures (rocksalt,
fluorite, blende, wurtzite, rutile, ReO3; mixed oxides: perosvkite
and spinels). Silicates.
Bonding in solids. Ionic solids; the role
of ion size; Shannon-Prewitt model for ions. Transition metal
compounds and non-bonding electron effects. Crystal field theory.
Band model for metals and semiconductors.
Crystal defects and non-stoichiometry. Role
of point defects in diffusion in solids. Ionic conductivity. Some
important solid state electrolytes for batteries and fuel
cells.
Carbon based materials: conducting
polymers, structure and properties. Polymer electrolyte for Li
batteries. Proton conducting polymers for fuel cells electrolytes.
Fullerenes and fullerides, synthesis and properties. Carbon
nanotubes, graphene and their application in polymer
nanocomposites.
Layered solids: layered double hydroxides,
clays and their modification to improve the compatibility with
polymers. Preparation of polymer nanocomposites using organoclays.
Flame retardant properties of LDH and organoclay based polymer
nanocomposites.
