Reference excerpt

Paula L. Diaconescu is a Romanian-American chemistry professor at the University of California, Los Angeles. She is known for her research on the synthesis of redox active transition metal complexes, the synthesis of lanthanide complexes, metal-induced small molecule activation, and polymerization reactions. She is a fellow of the American Association for the Advancement of Science.

Biography Diaconescu was born in Romania and received a Bachelor of Science degree from the University of Bucharest in 1998 conducting research on transition metal complexes and f-block metals. In 2003, Diaconescu received a PhD in chemistry from the Massachusetts Institute of Technology working with Christopher C. Cummins on uranium chemistry. Before joining the faculty at UCLA in 2005, she spent two years as a postdoctoral fellow at the California Institute of Technology with Robert Grubbs. As of August 2020, Diaconescu was chosen to lead the $1.8 million National Science Foundation (NSF) Center for Integrated Catalysis. The goal of the CIC was to simulate biological systems at play in the formation of synthetic chemical catalytic processes. Integrated Catalysis aims to combine spatial and temporal control in order to synthesize polymers with high complexity in a single reactor.

Research While Diaconescu is best known for her work on the reactivity of early transition metals, lanthanides, and actinides, she has also contributed to the field of redox active ligand systems for small molecule activation. Her group has exploited ferrocene's electronic and redox properties to enable catalytic transformations with electrophilic transition metal centers. Diaconescu's research on redox active systems is studying how ferrocene's electronic and redox properties when strategically incorporated into a ligand affect the reactivity of d-block metal complexes. This extends to redox switchable catalysis and small molecule activation with applications in polyaniline nanofiber supporting metal catalysis and bioorganometallic polymers. She recognized that redox-switchable catalysis can generate multiple catalytically active species with varying reactivity. The idea is that a compound can have orthogonal reactivity between the oxidized and reduced forms of the catalyst. The ring-opening polymerization of cyclic ethers and esters as well as the polymerization of alkenes has been exploited with catalysts containing ferrocene.

Awards Diaconescu received a Sloan Fellowship in 2009, and received the Humboldt Foundation's Friedrich Wilhelm Bessel Research Award in 2014. In 2015, she was named a Guggenheim Fellow, and Diaconescu was named a fellow of the American Association for the Advancement of Science in 2019.

Worked examples

Example 1 — a first encounter with Paula Diaconescu

Start with the simplest possible case. Write down what Paula Diaconescu 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 Paula Diaconescu 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 Paula Diaconescu 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 Paula Diaconescu

In research: Paula Diaconescu 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 Paula Diaconescu 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: Paula Diaconescu is common in secondary-school and first-year university syllabi. It links to neighbouring topics 21st-century American chemists, 21st-century American women scientists, American people of Romanian descent, so understanding it makes those chapters shorter.
In everyday life: Look for Paula Diaconescu 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.
