Maria Zaharescu

Maria Zaharescu is a chemistry topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Maria Zaharescu rather than just read about it. In short: Maria-Magdalena Zaharescu (born 1938) is a Romanian chemist, specializing in the physical chemistry of oxide systems. Zaharescu was a Senior Researcher and Head of Department at the Ilie Murgulescu Institute of Physical Chemistry of the Romanian Academy in Bucharest.

Key takeaways

Maria Zaharescu belongs to chemistry; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Maria Zaharescu to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Maria Zaharescu from memory before moving on to harder problems.

Reference excerpt

Maria-Magdalena Zaharescu (born 1938) is a Romanian chemist, specializing in the physical chemistry of oxide systems. Zaharescu was a Senior Researcher and Head of Department at the Ilie Murgulescu Institute of Physical Chemistry of the Romanian Academy in Bucharest. In 2001, she was elected a corresponding member of the Romanian Academy and became a full member in June 2015. On December 1, 2017, she was awarded a Knight of the Order of the Star of Romania. She was one of the 100 women scientists featured in "Successful Women Ceramic and Glass Scientists and Engineers: 100 Inspirational Profiles" by Lynnette Madsen (2016).

Scientific interests Her scientific interests include:

Physical chemistry of oxide systems (reactions mechanisms, thermal phase equilibria, structure-properties correlations). Sol-gel science (sol-gel chemistry, nanostructured oxide films and powders, inorganic-organic hybrids, nanocomposites, oxide nanotubes). She introduced and developed the field of sol-gel research in Romania. Vitreous oxide systems with special properties (thermally and chemically stable)

Education She graduated from the Babeș-Bolyai University, Faculty of Chemistry, and received her PhD from the Institute of Chemistry, both in Cluj-Napoca.

Scientific activity More than 350 scientific papers from which over 250 published in internationally recognized ISI journals, including Journal of Sol-Gel Science and Technology; Journal of the European Ceramic Society; Journal of the American Ceramic Society; Journal of Materials Chemistry; Journal of Materials Science; Journal of Materials Research; Materials Chemistry and Physics; Journal of Non-Crystalline Solids; Journal of Thermal Analysis and Calorimetry; Applied Surface Science; Journal of Nanoparticle Research; Ceramics International; Thin Solid Films; Revue Roumaine de Chimie, etc. as well as 3 patents and 8 book chapters edited by the Romanian Academy and international publishers. In 2016, Zaharescu published 1D Oxide Nanostructures Obtained by Sol-Gel and Hydrothermal Methods, as part of the SpringerBriefs series offered by the Springer Publishing Company. International research projects in collaboration with Davis University, USA (funded by NST-USA), National Technical University of Athens, Greece (funded by NATO) and universities from Czech Republic, Bulgaria, France, Slovenia Member of the International Society of Sol-Gel Science Member of the American Ceramic Society – Basic Research Division Member of the American Nano Society Member of the editorial board of the Journal of Sol-Gel Science and Technology.

Awards 1971 - Gheorghe Spacu Award, Romanian Academy 1982 - Scientific Merit Medal, Romania 1983 - Scientific Order Third Degree, Romania 2007 - Honor Award and Gheorghe Spacu Medal, Romanian Society of Chemistry 2017 - Knight of the Order of the Star of Romania

Notes

Worked examples

Example 1 — a first encounter with Maria Zaharescu

Start with the simplest possible case. Write down what Maria Zaharescu claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, 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 Zaharescu 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 Zaharescu 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 Zaharescu

In research: Maria Zaharescu appears in chemistry 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 Zaharescu 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 Zaharescu is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1938 births, Babeș-Bolyai University alumni, Knights of the Order of the Star of Romania, so understanding it makes those chapters shorter.
In everyday life: Look for Maria Zaharescu 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.
