Reference excerpt

Maria D. Ellul is a retired ExxonMobil materials scientist known for her contributions to and development of commercial polyolefin and polyamide specialty thermoplastic elastomers, and recognized as one of the first prominent women scientists in the rubber industry.

Education Ellul was born in Malta. In 1977, she earned a B.Sc. in chemistry at The Royal University of Malta and was employed as an intern with Sterling Organics. In 1979, she completed the M.Sc. degree in Polymer Science from North London Polytechnic. She earned her Ph.D. in Polymer Science from The University of Akron in 1984 under advisor Alan Gent.

Career Ellul's first post-baccalaureate employment was in 1977 as a chemist at Dowty Seals Ltd. Her first employer following her doctorate was GenCorp/General Tire. In that role she conducted research on tire materials, adhesion of rubber and Fracture Mechanics. She joined ExxonMobil Chemical Co. in 1991 with its subsidiary Advanced Elastomer Systems. She held positions of increasing responsibility, eventually rising to principal scientist and retired as senior research associate. She is known for both fundamental and applied contributions to polyolefin and polyamide based thermoplastic elastomer materials. She developed methods to control the morphology and rheology of polymer blends, and contributed to the understanding of the kinetics and thermodynamics of polymer blends, block / graft copolymers and dynamic vulcanization. Ellul's research lead to the commercialization of many specialty polymers including Santoprene Thermoplastic Vulcanizates, Exxcore Dynamically Vulcanized Alloys, Vistamaxx, Butyl and EPDM. She is an associate editor for the scientific journal Rubber Chemistry & Technology.

Awards and recognition 1996 - Honored by the National Inventors Hall of Fame in the National Salute to Corporate Inventors. 1997 - Sparks–Thomas award from the ACS Rubber Division 1998 - Woman of the Year Award from Ohio Women's History Project 2005 - Chemistry of Thermoplastic Elastomers Award from the ACS Rubber Division 2010 - Department of Polymer Science Outstanding Alumni Award from The University of Akron 2016 - ExxonMobil Chiefs' Award

Worked examples

Example 1 — a first encounter with Maria D. Ellul

Start with the simplest possible case. Write down what Maria D. Ellul claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Maria D. Ellul before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Maria D. Ellul ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Maria D. Ellul

In research: Maria D. Ellul appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Maria D. Ellul in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Maria D. Ellul is common in secondary-school and first-year university syllabi. It links to neighbouring topics ExxonMobil people, Living people, Polymer scientists and engineers, so understanding it makes those chapters shorter.
In everyday life: Look for Maria D. Ellul outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
