Reference excerpt

Zhichuan (Jason) Xu (Chinese: 徐梽川) is a materials scientist and electrochemist specializing in electrocatalysis and energy conversion. He is a President's Chair Professor in the School of Materials Science and Engineering at Nanyang Technological University (NTU), director of the Maritime Energy & Sustainable Development Centre of Excellence and director of the Centre of Advanced Catalysis Science and Technology. He is a Fellow of the Academy of Engineering, Singapore and the Royal Society of Chemistry.

Education and career Zhichuan completed his undergraduate studies in Chemistry and his doctoral studies in Electroanalytical Chemistry at Lanzhou University, China. His PhD training was conducted at multiple institutions, including Lanzhou University, the Institute of Physics, Chinese Academy of Sciences (CAS), and Brown University. Following his PhD, he carried out research in the State University of New York at Binghamton as a research associate and later at Massachusetts Institute of Technology as a postdoctoral researcher. In 2012, he joined the School of Materials Science and Engineering, Nanyang Technological University (NTU) as an Assistant Professor. In 2017, he was promoted to Associate Professor and became a Full Professor in 2021. He is currently a President's Chair Professor at NTU. Xu was one of the founders and the former President of the Electrochemical Society (ECS) Singapore Section.

Research Zhichuan has worked on the influence of electron spin on electrocatalytic reactions. His work established a mechanistic foundation for spin-aligned intermediates coupling mechanism in electrocatalysis. This effect was identified in different intermediates coupling processes, such as O-O coupling or N-N-coupling. Xu's group analyzed the correlation between magnetic domains and spin-related enhancement of oxygen evolution reaction (OER). The spin-aligned O–O coupling between surface M–O• oxyl radicals on magnetic domains is identified as a key step in triplet oxygen formation. This spin-aligned intermediate coupling was subsequently extended to ammonia oxidation reaction (AOR), where thin-film catalysts with controlled magnetic domains revealed that spin alignment selectively lowers the energy barrier for N–NH dimerization and promotes N2 formation. He has also contributed to the understanding of transition-metal oxide electrocatalysts and standard electrocatalytic measurements. His work on spinel oxides identified the eg occupancy of the octahedral site as a descriptor for governing oxygen electrocatalytic activity and revealed how metal–oxygen covalency and controlled surface reconstruction determine activity and stability. He used of machine-learning methods to accelerate the spinel catalyst screening and design. Besides, related studies on iridium-based perovskite oxides under acidic conditions demonstrated lattice-site-dependent metal leaching processes that generate highly active reconstructed IrOx surface phases. He has also provided guidelines addressing reproducibility and best practices in electrocatalysis measurements, helping to standardize evaluation methods across water-splitting and fuel-cell research.

Worked examples

Example 1 — a first encounter with Zhichuan J. Xu

Start with the simplest possible case. Write down what Zhichuan J. Xu claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Zhichuan J. Xu 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 Zhichuan J. Xu 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 Zhichuan J. Xu

In research: Zhichuan J. Xu appears in astronomy 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 Zhichuan J. Xu 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: Zhichuan J. Xu is common in secondary-school and first-year university syllabi. It links to neighbouring topics Academic staff of Nanyang Technological University, Electrochemists, Lanzhou University alumni, so understanding it makes those chapters shorter.
In everyday life: Look for Zhichuan J. Xu 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.
