Engineered barrier system
An engineered barrier system is the set of engineered materials in a geological repository, including canisters, buffer, and backfill, that isolates radioactive waste from the biosphere.
Engineered cardiac patch
An engineered cardiac patch is a laboratory-grown sheet of heart muscle implanted on an injured heart to add contractile tissue and support repair after a heart attack.
Engineered cementitious composite
Engineered cementitious composite (ECC), also called strain-hardening cementitious composite or bendable concrete, is a fiber-reinforced cement material that stretches over 300 times more than ordinary concrete.
Engineered cytochrome P450 late-stage C–H oxidation
Engineered cytochrome P450 late-stage C–H oxidation uses protein-engineered P450 enzymes to insert oxygen into specific, unactivated carbon–hydrogen bonds of complex molecules such as drugs and natural products.
Engineered living material for carbon capture
An engineered living material for carbon capture is a construction material containing living microorganisms, typically cyanobacteria, that draw CO2 from the air and store it as biomass or carbonate minerals.
Engineered living materials
Engineered living materials (ELMs) are biohybrid materials combining living cells, often engineered bacteria, with nonliving matrices so the material can sense, adapt, and sometimes repair itself.
Engineered materials arrestor system
An engineered materials arrestor system (EMAS) is a bed of crushable cellular concrete blocks beyond a runway end that decelerates and safely stops an overrunning aircraft.
Engineered myoglobin
Engineered myoglobin refers to variants of the muscle protein myoglobin, altered by active-site mutation or cofactor substitution, that catalyze abiological reactions such as carbene transfer and alkene cyclopropanation.
Engineered subtilisin variants for industrial applications
Engineered subtilisin variants are protein-engineered forms of the bacterial serine protease subtilisin, modified by mutagenesis or directed evolution for stability in laundry detergents, leather processing, and other industrial uses.
Engineered virus-like particles (eVLPs)
Engineered virus-like particles (eVLPs) are noninfectious, nanoscale particles assembled from retroviral proteins that mimic viruses but carry no viral genome, delivering genome-editing proteins into cells.
Engineered wood
Engineered wood, also known as composite wood or manufactured boards, is a structural building material made by bonding veneers, strands, or particles with adhesives into products like plywood, I-joists, and glulam.
Engineering
Engineering applies mathematics, basic science, and engineering science to devise systems, components, and processes that meet desired needs within real-world constraints such as cost, safety, regulations, and schedule.
Engineering & Development Group
Edgo, formally the Engineering & Development Group, is an Amman-based energy-services group founded by Munib R. Masri in 1956, providing oilfield services across the Middle East and Africa.
Engineering Capital
Engineering Capital is a seed-stage venture capital firm in Palo Alto, California, founded in 2015 by Ashmeet Sidana to lead seed rounds in enterprise software companies.
Engineering Council
The Engineering Council is the regulatory body for the engineering profession in the United Kingdom, incorporated by Royal Charter in 1981 and holding the national register of engineers and technicians.
Engineering Council of South Africa
The Engineering Council of South Africa (ECSA) is the statutory body that regulates the engineering profession in South Africa under the Engineering Profession Act, 2000, registering practitioners and accrediting programs.
Engineering design process
The engineering design process is the iterative process engineers use to define a problem, generate and test solutions, and redesign until one meets the criteria and constraints.
Engineering drawing
An engineering drawing, also called engineering graphics, is a controlled, numbered, revised document specifying a part or assembly for manufacture and inspection, prepared manually or with CAD.
Engineering ethics
Engineering ethics: study of moral issues in engineering, defined by Martin and Schinzinger, centered on NSPE-style codes holding public safety paramount, shaped by history and cases like Challenger.
Engineering fit
An engineering fit is the degree of tightness or looseness between two mating mechanical parts, such as a shaft in a hole, classified as clearance, transition, or interference.
Engineering management
Engineering management is a field combining engineering's technical knowledge with management's organizational skills to lead technical teams and projects, first taught as a graduate degree at Drexel University in 1959.
Engineering News-Record
Engineering News-Record, or ENR, is an American weekly trade magazine covering the construction industry, best known for its annual rankings of the largest contractors and design firms.
Engineering notation
Engineering notation, or ENG notation, is a version of scientific notation in which the exponent of 10 is always a multiple of 3, matching SI prefixes like kilo and milli.
Engineering Recommendation G99
Engineering Recommendation G99, also known as EREC G99, is an Energy Networks Association standard governing connections of solar, wind, and battery generation to Great Britain's distribution networks.
Engineering Structures (journal)
Engineering Structures is a peer-reviewed journal covering structural engineering research, from buildings and bridges to earthquake and wind engineering, published by Elsevier since 1978 and appearing 24 times a year.
Engineering technician
An engineering technician, sometimes abbreviated EngTech, is a worker who supports engineers in testing, drafting, inspection, installation, and maintenance, typically entering the field with an associate degree.
Engineering tolerance
An engineering tolerance, also called a manufacturing tolerance, is the permissible variation in a part's dimensions set so the part still functions and assembles properly.
Engineering, procurement, and construction
Engineering, procurement, and construction (EPC), also called turnkey contracting, is a project delivery model in which a single contractor handles design, procurement, and construction, usually for a fixed price.
Engineers Australia
Engineers Australia, formally the Institution of Engineers, Australia, is the national peak body for engineers, founded in 1919, which accredits engineering education and assesses migrants.
Engineers Ireland
Engineers Ireland is the professional body for engineers in Ireland, tracing its roots to 1835 and representing over 30,000 members; it awards the Chartered Engineer title.
