Materials Science

With a basic understanding of the origins of properties, materials can be selected or designed for an enormous variety of applications, ranging from structural steels to computer microchips. Materials science is therefore important to engineering activities such as electronics, aerospace, telecommunications, information processing, nuclear power, and energy conversion. Phases such as Stone Age, Bronze Age, Iron Age, and Steel Age are historic, if arbitrary examples. Materials science has driven, and been driven by, the development of revolutionary technologies such as rubbers, plastics, semiconductors, and biomaterials. Materials science and engineering research integrates advances in theory and experimental breakthroughs, via a deeply interdisciplinary approach and extensive collaborations with industry.

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.

The dividing lines between the various types of plastics is not based on material but rather on their properties and applications. Polycarbonate would be normally considered an engineering plastic (other examples include PEEK, ABS). Such plastics are valued for their superior strengths and other special material properties. They are usually not used for disposable applications, unlike commodity 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.

  • Phases such as Stone Age, Bronze Age, Iron Age, and Steel Age are historic, if arbitrary examples.
  • 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.
  • Crystallography is the science that examines the arrangement of atoms in crystalline solids.

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. It is one of our top goals to continue to attract the best and brightest students from the U.S. and around the world. We feel that the mixture of a core curriculum in materials science and engineering fundamentals and leading-edge independent research is exceptional preparation for future scientists and engineers.

Many students will use this as an opportunity to build contacts with future employers. UW MSE students enjoy the highest undergraduate to faculty member ratio among peer departments nationwide. Thermodynamics is concerned with heat and temperature and their relation to energy and work.

Department of Materials Science and Engineering

Materials science and engineering is a cross-disciplinary subject that focuses on how materials behave and how their structure controls their behaviour. You can expect to delve deeper into the relationships between fundamental science and how different groups of materials, such as ceramics, composites, metals, nanomaterials, textiles, and polymers, can be engineered to achieve better performance. Materials science is an interdisciplinary field concerned with the understanding and application of the properties of matter. Materials scientists study the connections between the underlying structure of a material, its properties, its processing methods and its performance in applications.

Other semiconductor materials include germanium, silicon carbide, and gallium nitride and have various applications. 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. For example, steels are classified based on 1/10 and 1/100 weight percentages of the carbon and other alloying elements they contain. Thus, the extracting and purifying methods used to extract iron in a blast furnace can affect the quality of steel that is produced.

Hence, materials science and engineering can appeal to those with a broad interest in fundamental science as well as design, manufacturing, and engineering. Materials science engineers explore materials’ scientific fundamentals, design, and processing for real-world applications. They apply the basic principles of chemistry and physics to understand the structure and properties of materials. They design processes to manipulate materials to meet the needs of modern technology. Another application of materials science is the study of ceramics and glasses, typically the most brittle materials with industrial relevance.

The versatility of PVC is due to the wide range of plasticisers and other additives that it accepts.[19] The term « additives » in polymer science refers to the chemicals and compounds added to the polymer base to modify its material properties. 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.

We work with a diverse set of materials ranging from metals, polymers, ceramics, and composites. We apply them in various industries, including energy, transportation, tissue engineering, drug delivery, construction, nanotechnology, and more. We use a range of processes to make the materials from organic and polymer synthesis, additive manufacturing, coating, evaporation, machine learning, and beyond.

Many ceramics and glasses exhibit covalent or ionic-covalent bonding with SiO2 (silica) as a fundamental building block. Ceramics – not to be confused with raw, unfired clay – are usually seen in crystalline form. The vast majority of commercial glasses contain a metal oxide fused with silica.

The microstructure of materials reveals these larger defects and advances in simulation have allowed an increased understanding of how defects can be used to enhance material properties. Stanford’s Department of Materials Science and Engineering (MSE) focuses on the structures and properties of nanoscale components. You could work anywhere from Small and Medium Enterprises (SMEs), start-ups and big business to academic research, via government and Non-Governmental Organisations (NGOs).

Finally, spherical nanoparticles have three dimensions on the nanoscale, i.e., the particle is between 0.1 and 100 nm in each spatial dimension. The terms nanoparticles and ultrafine particles (UFP) often are used synonymously although UFP can reach into the micrometre range. In describing nanostructures, it is necessary to differentiate between the number of dimensions on the nanoscale.

Mostly, materials do not occur as a single crystal, but in polycrystalline form, as an aggregate of small crystals or grains with different orientations. Because of this, the powder diffraction method, which uses diffraction patterns of polycrystalline samples with a large number of crystals, plays an important role in structural determination. Most materials have a crystalline structure, but some important materials do not exhibit regular crystal structure. Polymers display varying degrees of crystallinity, and many are completely non-crystalline.

Active materials are those that take part directly in energy conversion—such as solar cells, batteries, catalysts, and superconducting magnets. Our department collaborates with most other Northwestern engineering and science departments, as well as with Northwestern’s Feinberg School of Medicine and outside institutions, such as the Art Institute of Chicago. We also work closely with national laboratories, including nearby Argonne National Laboratory, home of the Advanced Photon Source and the Center for Nanoscale Materials. After curing at high temperature in an autoclave, the laminate is pyrolized to convert the resin to carbon, impregnated with furfuryl alcohol in a vacuum chamber, and cured-pyrolized to convert the furfuryl alcohol to carbon. To provide oxidation resistance for reusability, the outer layers of the RCC are converted to silicon carbide.

At the high temperatures used to prepare glass, the material is a viscous liquid which solidifies into a disordered state upon cooling. Fibers of glass are also used for long-range telecommunication and optical transmission. Scratch resistant Corning Gorilla Glass is a well-known example of the application of materials science to drastically improve the properties of common components. 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.

The first academic department of its kind in the world, the Department of Materials Science and Engineering at Northwestern University leads the field in materials innovation and education. Driven by curiosity and the thrill of discovery, faculty members use a transdisciplinary approach to connect fundamental science with engineering research, enabling technologies that improve our lives. Another application of materials science in industry is making composite materials. For example, any crystalline material will contain defects such as precipitates, grain boundaries (Hall–Petch relationship), vacancies, interstitial atoms or substitutional atoms.
