Metals are crystalline because the bond via metallic bonding, are unrestricted as to number and position of nearest neighbor atoms, and have dense atomic packing. Due to these… traits, they form a lattice microstructure (i.e., crystal) (MORE)
Crystalline and Amorphous are two forms of Carbon. Crystalline is the form in which most of the substances consists of crystals or so. Examples are: Diamond, Graphite and Full…erene. Amorphous or non-crystalline is the form in which every substance is aerated or something as a gas. Examples are: Coke, Coal and etc. (MORE)
The crystalline lens is part of the refracting system of the eye and in addition to the cornea helps focus light onto the retina. The lens can also alter shape (accomm…odation) when it is stretched by very small muscles within the eye, this allows us to alter the focus of the eye (i.e. look from the TV to a book) Around mid 40's the ability to change the shape of the lens reduces and eventually is non existent. This happens to everyone and is called presbyopia, and why reading glasses and varifocals are required. The lens is also where cataracts form. Clouding of the lens causes reduction in visual acuity. This can be rectified with a simple operation. (MORE)
Crystalline solids are usually polar molecules or ionic structuresthat create a lattice. One such example of an ionic lattice is salt(NaCl) where the positive sodium ions are …attracted to the negativechloride ions. An example of a polar molecular lattice is glucose.One part of the molecule has a greater electronegativity than therest, and bonds adhering to that pattern to other molecules ontheir less electronegative portions.

Liquid crystals (LCs) are substances that exhibit a phase of matter that has properties between those of a conventional liquid and those of a solid crystal. For instance…, an LC may flow like a liquid, but its molecules may be oriented in a crystal-like way. Liquid crystals (LCs) are substances that exhibit a phase of matter that has properties between those of a conventional liquid and those of a solid crystal. For instance, an LC may flow like a liquid, but its molecules may be oriented in a crystal-like way. basically its like glass. glass is not actually a solid. it is always in motion, but we cant see it because it moves so slow. if you ever go to a very old house, you will notice that the glass at the bottom of the window is much thincker, and your vision may seem blury from its sliding due to gravity.

Crystalline ceramic materials are not amenable to a great range of processing. Methods for dealing with them tend to fall into one of two categories -- either make the ceramic… in the desired shape, by reaction in situ, or by "forming" powders into the desired shape, and then sintering to form a solid body. Ceramic forming techniques include shaping by hand (sometimes including a rotation process called "throwing"), slip casting, tape casting (used for making very thin ceramic capacitors, e.g.), injection molding, dry pressing, and other variations. Details of these processes are described in the two books listed below. A few methods use a hybrid between the two approaches. (MORE)
I have Masters degree with Distinction and Student of the Year Prize in" Corrosion of Engineering Materials" from Imperial College London, first degree in Chemistry from University of Central Lancashire and also did Technology, Material Science and Engineering and Mathematics from the Open University. I also taught Masters Students at Imperial for 3 years.
