This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Kazunari Dōmen rather than just read about it. In short: Kazunari Dōmen is a Japanese chemist at the University of Tokyo and Shinshū University. He is known for his work on the large-scale synthesis of hydrogen by photocatalytic water splitting.

Key takeaways

Kazunari Dōmen belongs to chemistry; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Kazunari Dōmen to a quantity you can measure, compute or draw — that is where exam questions come from.

Reference excerpt

Kazunari Dōmen is a Japanese chemist at the University of Tokyo and Shinshū University. He is known for his work on the large-scale synthesis of hydrogen by photocatalytic water splitting.

Career Dōmen earned a bachelor's degree in chemistry from the University of Tokyo in 1976, a master's degree in 1979, and a Ph.D. in chemistry in 1982 with his thesis Photocatalytic Reaction on Some Semiconductor Powders. In the same year he was appointed assistant professor at the Tokyo Institute of Technology. He stayed as a postdoctoral fellow at the IBM Almaden Research Center in San José, California in 1985/86. He was promoted to associate professor at the Tokyo Institute of Technology in 1990 and received a full professorship in 1996. Dōmen returned to his alma mater in 2004 as a professor. Together with Takashi Hisatomi, he has also been running a research laboratory at Shinshū University since 2017.

Honours Clarivate Citation Laureate (2024), for "fundamental research on photocatalysts for water splitting and the construction of solar hydrogen production systems".

Worked examples

Example 1 — a first encounter with Kazunari Dōmen

Start with the simplest possible case. Write down what Kazunari Dōmen 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 Kazunari Dōmen 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 Kazunari Dōmen 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 Kazunari Dōmen

In research: Kazunari Dōmen 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 Kazunari Dōmen 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: Kazunari Dōmen is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1953 births, Academic staff of the University of Tokyo, Chemist stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Kazunari Dōmen 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.
