Katsuhiko Ariga 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 Katsuhiko Ariga rather than just read about it. In short: Katsuhiko Ariga (有賀克彦, Ariga Katsuhiko; born 1962) is a Japanese chemist specializing in nanotechnology and self-assembly. He was educated at the Tokyo Institute of Technology, where he defended his PhD in 1990 and later worked as assistant professor.

Key takeaways

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

Reference excerpt

Katsuhiko Ariga (有賀克彦, Ariga Katsuhiko; born 1962) is a Japanese chemist specializing in nanotechnology and self-assembly. He was educated at the Tokyo Institute of Technology, where he defended his PhD in 1990 and later worked as assistant professor. Since 2004 he carries out research at the National Institute for Materials Science, and teaches at the University of Tokyo, where he is a full professor. Ariga is a Fellow of the Royal Society of Chemistry (2013) and an editor of the journal Science and Technology of Advanced Materials.

Selected publications According to the Web of Science Ariga published five articles with more than 700 citations each:

Worked examples

Example 1 — a first encounter with Katsuhiko Ariga

Start with the simplest possible case. Write down what Katsuhiko Ariga 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 Katsuhiko Ariga 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 Katsuhiko Ariga 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 Katsuhiko Ariga

In research: Katsuhiko Ariga 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 Katsuhiko Ariga 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: Katsuhiko Ariga is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1962 births, Academic staff of Tokyo Institute of Technology, Academic staff of the University of Tokyo, so understanding it makes those chapters shorter.
In everyday life: Look for Katsuhiko Ariga 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.
