Jingdong Zhang

Jingdong Zhang 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 Jingdong Zhang rather than just read about it. In short: Jingdong Zhang (June 2, 1968 – January 09, 2020) was a Chinese–Danish chemist and professor of chemistry at the Technical University of Denmark. Her research considered nanochemistry and the novel materials for catalysis, as well as the development of advanced characterisation techniques such as scanning tunnelling microscopy and atomic force microscopy.

Key takeaways

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

Reference excerpt

Jingdong Zhang (June 2, 1968 – January 09, 2020) was a Chinese–Danish chemist and professor of chemistry at the Technical University of Denmark. Her research considered nanochemistry and the novel materials for catalysis, as well as the development of advanced characterisation techniques such as scanning tunnelling microscopy and atomic force microscopy. She was elected to the Akademiet for de Tekniske Videnskaber in 2017.

Early life and education Zhang was born in 1968 in China. She studied chemistry and environmental engineering at Shanghai University. After earning her master's degree, Zhang moved to the Chinese Academy of Sciences' Changchun Institute of Applied Chemistry (CIAC) for her graduate research. Here she worked under the supervision of Erkang Wang.

Research and career Zhang was appointed to the Exploratory Research for Advanced Technology (ERATO) project, which saw her working on electrochemiscopy at the Kyushu University in Sendai, Japan. She joined the faculty at the Technical University of Denmark in 1998, where she was eventually promoted to professor in 2016. Her research considered electrochemistry for nanomedicines and sustainable energy. In particular, she was interested in the electrochemistry that occurs at interfaces. During the late nineties, electrochemistry rapidly grew as a research area, integrating aspects of solid state physics and materials science. Zhang was quick to pick up new materials and characterisation techniques, including atomic force microscopy at single molecule resolution. She was particularly interested in redox metalloproteins and enzymes and new (bio)electrochemical surfaces. These surfaces included graphene, nanoparticles and nanoporous metallic surfaces. She was awarded the Danish Society of Engineers Agnes and Betzy Prize in 2011. The following year she was elected to the Royal Danish Academy of Sciences and Letters. In 2017 Zhang was appointed to the Akademiet for de Tekniske Videnskaber. Zhang was a member of the editorial board of ChemElectroChem. A special issue of ChemElectroChem honouring Zhang and her legacy was published in 2021.

Personal life Zhang was married to Qijin Chi, a chemist at the Technical University of Denmark, with whom she had one son.

Worked examples

Example 1 — a first encounter with Jingdong Zhang

Start with the simplest possible case. Write down what Jingdong Zhang 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 Jingdong Zhang 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 Jingdong Zhang 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 Jingdong Zhang

In research: Jingdong Zhang 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 Jingdong Zhang 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: Jingdong Zhang is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1968 births, 2020 deaths, Academic staff of the Technical University of Denmark, so understanding it makes those chapters shorter.
In everyday life: Look for Jingdong Zhang 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.
