Earth Materials Lecture Notes
Lecture note on earth material: Fundamentals of earth materials, strategic minerals, metals, and their geochemical importance and significance Earth materials-Atoms and elements, elements and their formation in the universe, cosmochemistry Chemical bonds that characterize Earth materials with symmetry, lattices, point groups, and space groups. It further discusses metamorphic petrology, which is rich in dealing with the processes and transformations that occur in Earth's crust. The resource is also important to students of geology, mineralogy, and other related courses for it provides an overview of the material composition and structure of the Earth.

The Principles of Leather Manufacture by H. R. Procter
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.
