Chemical kinetics is the study of the rates at which systems that are out of equilibrium change under the influence of various forces. When applied to materials science, it deals with how a material changes with time moves from non-equilibrium to equilibrium state due to application of a certain field. It details the rate of various processes evolving in materials including shape, size, composition and structure.
Diffusion is important in the study of kinetics as this is the most common mechanism by which materials undergo change. Kinetics is essential in processing of materials because, among other things, it details how the microstructure changes with application of heat.
Materials science has received much attention from researchers. In most universities, many departments ranging from physics to chemistry to chemical engineering , along with materials science departments, are involved in materials research. Research in materials science is vibrant and consists of many avenues. The following list is in no way exhaustive. It serves only to highlight certain important research areas. Nanomaterials research takes a materials science-based approach to nanotechnology , leveraging 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.
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. 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. Semiconductors, metals, and ceramics are used today to form highly complex systems, such as integrated electronic circuits, optoelectronic devices, and magnetic and optical mass storage media.
These materials form the basis of our modern computing world, and hence research into these materials is of vital importance. Semiconductors are a traditional example of these types of materials. They are materials that have properties that are intermediate between conductors and insulators. Their electrical conductivities are very sensitive to impurity concentrations, and this allows for the use of doping to achieve desirable electronic properties.
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.
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.
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.
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 SiO 2 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. Filaments are commonly used for reinforcement in composite materials. Another application of materials science in industry is making composite materials. These are structured materials composed of two or more macroscopic phases.
Applications range from structural elements such as steel-reinforced concrete, to the thermal insulating tiles which play a key and integral role in NASA's Space Shuttle thermal protection system which is used to protect the surface of the shuttle from the heat of re-entry into the Earth's atmosphere. RCC is a laminated composite material made from graphite rayon cloth and impregnated with a phenolic resin. After curing at high temperature in an autoclave, the laminate is pyrolized to convert the resin to carbon, impregnated with furfural alcohol in a vacuum chamber, and cured-pyrolized to convert the furfural alcohol to carbon.
To provide oxidation resistance for reuse ability, the outer layers of the RCC are converted to silicon carbide. Other examples can be seen in the "plastic" casings of television sets, cell-phones and so on. These plastic casings are usually a composite material made up of a thermoplastic matrix such as acrylonitrile butadiene styrene ABS in which calcium carbonate chalk, talc , glass fibers or carbon fibers have been added for added strength, bulk, or electrostatic dispersion.
These additions may be termed reinforcing fibers, or dispersants, depending on their purpose. Polymers are chemical compounds made up of a large number of identical components linked together like chains.
They are an important part of materials science. Polymers are the raw materials the resins used to make what are commonly called plastics and rubber.
Plastics and rubber are really the final product, created after one or more polymers or additives have been added to a resin during processing, which is then shaped into a final form. Plastics which have been around, and which are in current widespread use, include polyethylene , polypropylene , polyvinyl chloride PVC , polystyrene , nylons , polyesters , acrylics , polyurethanes , and polycarbonates and also rubbers which have been around are natural rubber, styrene-butadiene rubber, chloroprene , and butadiene rubber.
Plastics are generally classified as commodity , specialty and engineering plastics. Polyvinyl chloride PVC is widely used, inexpensive, and annual production quantities are large. It lends itself to a vast array of applications, from artificial leather to electrical insulation and cabling, packaging , and containers. Its fabrication and processing are simple and well-established. The versatility of PVC is due to the wide range of plasticisers and other additives that it accepts.
The term "additives" in polymer science refers to the chemicals and compounds added to the polymer base to modify its material properties. Such plastics are valued for their superior strengths and other special material properties.
Glass Physics and Chemistry
They are usually not used for disposable applications, unlike commodity plastics. Specialty plastics are materials with unique characteristics, such as ultra-high strength, electrical conductivity, electro-fluorescence, high thermal stability, etc. The dividing lines between the various types of plastics is not based on material but rather on their properties and applications. For example, polyethylene PE is a cheap, low friction polymer commonly used to make disposable bags for shopping and trash, and is considered a commodity plastic, whereas medium-density polyethylene MDPE is used for underground gas and water pipes, and another variety called ultra-high-molecular-weight polyethylene UHMWPE is an engineering plastic which is used extensively as the glide rails for industrial equipment and the low-friction socket in implanted hip joints.
The study of metal alloys is a significant part of materials science. Of all the metallic alloys in use today, the alloys of iron steel , stainless steel , cast iron , tool steel , alloy steels make up the largest proportion both by quantity and commercial value. Iron alloyed with various proportions of carbon gives low, mid and high carbon steels. An iron-carbon alloy is only considered steel if the carbon level is between 0. For the steels, the hardness and tensile strength of the steel is related to the amount of carbon present, with increasing carbon levels also leading to lower ductility and toughness.
Heat treatment processes such as quenching and tempering can significantly change these properties, however. Cast Iron is defined as an iron—carbon alloy with more than 2.
Nickel and Molybdenum are typically also found in stainless steels. Other significant metallic alloys are those of aluminium , titanium , copper and magnesium.
Copper alloys have been known for a long time since the Bronze Age , while the alloys of the other three metals have been relatively recently developed. Due to the chemical reactivity of these metals, the electrolytic extraction processes required were only developed relatively recently. The alloys of aluminium, titanium and magnesium are also known and valued for their high strength-to-weight ratios and, in the case of magnesium, their ability to provide electromagnetic shielding.
These materials are ideal for situations where high strength-to-weight ratios are more important than bulk cost, such as in the aerospace industry and certain automotive engineering applications. The study of semiconductors is a significant part of materials science.
A semiconductor is a material that has a resistivity between a metal and insulator.John Wiley and Sons, pp.
The journal welcomes manuscripts from all countries in the English or Russian language. Due to its higher electron mobility and saturation velocity compared to silicon, it is a material of choice for high-speed electronics applications.
The study of semiconductors is a significant part of materials science.
For the steels, the hardness and tensile strength of the steel is related to the amount of carbon present, with increasing carbon levels also leading to lower ductility and toughness. Materials science examines the structure of materials from the atomic scale, all the way up to the macro scale.
