This lecture note
covers all the essential issues that need to be understood by an engineer
concerning the interplay between materials, structure, and properties.
Issues such as metallurgy, crystal physics, and Neumann's symmetry principle
are dealt with in detail. Equilibrium thermodynamics, neutron diffraction,
and spectroscopy are also touched on, with all discussions on the major
classes of materials and the emerging field of nanostructured materials.
Focusing on practical applications, it also takes into discussion the most
recent concepts, like Moore's Law and their implications to materials
engineering. Dedicated to the students and professionals in engineering,
this note establishes a scientific basis in choosing and performing the
materials.

This textbook, authored by Dr. Swati
Gangwar and Mr. Kapil Kumar, comprehensively covers the very basics of
material science and engineering. Classifications of materials are taken up
as metals, polymers, composite materials, and biomaterials; their properties
and applications are described. Crystal structures are discussed in terms of
Bravais lattices, Miller indices, and atomic packing factor. Students will
also be introduced to X-ray crystallography and how it might be applied for
the determination of inner structure of the materials. Its clarity in
structure and rich detail make it extremely useful for courses ranging from
introductory to advanced in material science and engineering. Significant
emphasis throughout the text, quite markedly, on the importance of
understanding material properties and their relationship with structure
toward an effective design and application of an engineering material.
The famous reference source H. R. Procter, The Principles of
Leather Manufacture, explores chemistry and the processes undertaken in the
manufacture of leather. Starting with a general overview relating to the
historical background and introduction concepts in leather manufacture, it
points to where the role of the living cell plays, the causative agents for
putrefaction, and also to antiseptics and disinfectants. It also covers the
chemical content of hides, the structure and growth of skin, and the
chemical processes by which it gets tanned - alum, chrome, and vegetable
tanning. The book also goes into the matter of physical chemistry of the
fibers of hides and water treatment in tanneries and methods for depilation,
deliming, and bating. The book is very valuable for any readers interested
in the chemical processes involved in leathering, giving both theoretical
knowledge and some practical insight into the tanning industry.
