    Nanomaterials research takes a materials science-based approach to nanotechnology , using advances in materials metrology and synthesis which have been developed in support of microfabrication research. Materials with structure at the nanoscale often have unique optical, electronic, or mechanical properties. The field of nanomaterials is loosely organized, like the traditional field of chemistry, into organic carbon-based nanomaterials such as fullerenes, and inorganic nanomaterials based on other elements, such as silicon. Examples of nanomaterials include fullerenes , carbon nanotubes , nanocrystals , etc. Main article: Biomaterial The iridescent nacre inside a nautilus shell A biomaterial is any matter, surface, or construct that interacts with biological systems. The study of biomaterials is called bio materials science. It has experienced steady and strong growth over its history, with many companies investing large amounts of money into developing new products. Biomaterials science encompasses elements of medicine , biology , chemistry , tissue engineering , and materials science. Biomaterials can be derived either from nature or synthesized in a laboratory using a variety of chemical approaches using metallic components, polymers , bioceramics , or composite materials. They are often intended or adapted for medical applications, such as biomedical devices which perform, augment, or replace a natural function. Such functions may be benign, like being used for a heart valve , or may be bioactive with a more interactive functionality such as hydroxylapatite coated hip implants. Biomaterials are also used every day in dental applications, surgery, and drug delivery. For example, a construct with impregnated pharmaceutical products can be placed into the body, which permits the prolonged release of a drug over an extended period of time. A biomaterial may also be an autograft , allograft or xenograft used as an organ transplant material.

    Ceramics and glasses[ edit ] Main article: Ceramic Si3N4 ceramic bearing parts Another application of material science is the structures of ceramics and glass typically associated with the most brittle materials. Bonding in ceramics and glasses uses covalent and ionic-covalent types with SiO2 silica or sand as a fundamental building block. Ceramics are as soft as clay or as hard as stone and concrete.

    Usually, they are crystalline in form. Most glasses contain a metal oxide fused with silica.

    At high temperatures used to prepare glass, the material is a viscous liquid. The structure of glass forms into an amorphous state upon cooling. Windowpanes and eyeglasses are important examples.

    Fibers of glass are also available. Scratch resistant Corning Gorilla Glass is a well-known example of the application of materials science to drastically improve the properties of common components.

    Diamond and carbon in its graphite form are considered to be ceramics. Engineering ceramics are known for their stiffness and stability under high temperatures, compression and electrical stress. Alumina, silicon carbide , and tungsten carbide are made from a fine powder of their constituents in a process of sintering with a binder. Hot pressing provides higher density material.

    Chemical vapor deposition can place a film of a ceramic on another material. Cermets are ceramic particles containing some metals.

    The wear resistance of tools is derived from cemented carbides with the metal phase of cobalt and nickel typically added to modify properties. Another application of materials science in industry is making composite materials.

    These are structured materials composed of two or more macroscopic phases. Structure and properties of White Cast iron, Malleable Cast iron, grey cast iron, Spheriodal graphite cast iron, Alloy cast irons.

    Classification of steels, structure and properties of plain carbon steels, Low alloy steels, Hadfield manganese steels, tool and die steels. Heat treatment of Alloys: Effect of alloying elements on Fe-Fe3C system, Annealing, normalizing, Hardening, TTT diagrams, tempering , Hardenability, surface — hardening methods, Age hardening treatment, Cryogenic treatment of alloys.

    Non-ferrous Metals and Alloys: Structure and properties of copper and its alloys, Aluminium and its alloys, Titanium and its alloys.

    Ceramic materials: Crystalline ceramics, glasses, cermaets, abrasive materials, nanomaterials — definition, properties and applications of the above. Hence, semiconductors form the basis of the traditional computer.

    This field also includes new areas of research such as superconducting materials, spintronics , metamaterials , etc. The study of these materials involves knowledge of materials science and solid-state physics or condensed matter physics. Computational materials science and engineering[ edit ] With continuing increases in computing power, simulating the behavior of materials has become possible.

    This enables materials scientists to understand behavior and mechanisms, explain properties formerly poorly understood, and even to design new materials. Efforts surrounding Integrated computational materials engineering are now focusing on combining computational methods with experiments to drastically reduce the time and effort to optimize materials properties for a given application.

    This involves simulating materials at all length scales, using methods such as density functional theory , molecular dynamics , Monte Carlo algorithm , dislocation dynamics, Phase field models , Finite element method , and many more.

    In industry[ edit ] Radical materials advances can drive the creation of new products or even new industries, but stable industries also employ materials scientists to make incremental improvements and troubleshoot issues with currently used materials. Industrial applications of materials science include materials design, cost-benefit tradeoffs in industrial production of materials, processing methods casting , rolling , welding , ion implantation , crystal growth , thin-film deposition , sintering , glassblowing , etc.

    Besides material characterization, the material scientist or engineer also deals with extracting materials and converting them into useful forms. Thus ingot casting, foundry methods, blast furnace extraction, and electrolytic extraction are all part of the required knowledge of a materials engineer. Often the presence, absence, or variation of minute quantities of secondary elements and compounds in a bulk material will greatly affect the final properties of the materials produced.

    Thus, the extracting and purifying methods used to extract iron in a blast furnace can affect the quality of steel that is produced.
