Reference excerpt

Byung Hee Hong is a professor of the department of chemistry at Seoul National University. Hong has developed the method of synthesizing large-scale graphene by chemical vapor deposition (CVD), which triggered chemical researches toward the practical applications of graphene. His papers reporting the large-scale growth of graphene have been intensively cited by many graphene researchers, showing the originality and the significance of his research. Graphene, the world thinnest material combines seemingly mutually exclusive material properties, which are of great importance for the flexible transparent conducting electrode market: it is at the same time both the best electric conductor we know and yet optically almost transparent; it is the world's strongest material and yet extremely flexible/bendable. Since its discovery in 2004 it has revolutionized our understanding of two dimensional crystals and their potential for device applications. The rapid development of graphene research and its impact on material science culminated Nobel Prize in Physics in 2010 for its discovery. Hong's contribution in large-area graphene synthesis has been recognized by Nobel committee, which is being exhibited in Nobel Museum. The unique electronic properties of this two dimensional carbon sheet are also of great interest to the semiconductor industry and have received considerable attention from leading high tech companies such as IBM, SAMSUNG, LG, Nokia, Google and Apple. Here, its potential for ultrafast transistors, energy storage and in particular flexible transparent conducting electrodes for, e.g. foldable touch screen panels generate most of the excitement. From a purely application point of view the key breakthrough took place in 2010: The founder of Graphene Square have invented an industry compatible growth (CVD) and transfer (Roll-to-Roll) process enabling the large scale synthesize of graphene for commercial applications. The related key patents have been registered in Korea, US, Japan, and China. Hong is also the founder of Graphene Square pioneered the large-scale synthesis of graphene by chemical vapor deposition (CVD), which triggered chemical research toward the practical application of graphene. His first report on CVD synthesis of graphene (Nature 2009) has recorded the world highest citations in chemistry among the papers published since 2009 (roughly 5000 times). One year later, he developed the synthesis of ultra-large graphene based on roll-to-roll methods and its application to flexible touch screens (Nature Nanotechnology. 2010), which is believed to be the first demonstration of application of graphene materials in practical electronic devices. For this contribution, he was invited to give a talk in the Nobel Symposium on Graphene (2010). He made more than 90 patent applications on graphene synthesis and applications, which corresponds to the world 2nd graphene-related inventor. Hong's research has been highlighted by Bloomberg, Businessweek, BBC, CNBC, New York Times, Financial Times, Russia Today, MIT Technology Review, C&EN News (cover story), Physics Today, and Physics World. He is now acting as Scientific Advisory Committee member of €1 billion Graphene Flagship project together with 4 Nobel Laureates and as Scientific Advisory Member of Cambridge Graphene Center, UK. He is currently an Advisory Member for CTO of LG Electronics. He served as a member of R&D Strategy and Planning Committee for Korean National Graphene Commercialization Project.

Worked examples

Example 1 — a first encounter with Hong Byung-hee

Start with the simplest possible case. Write down what Hong Byung-hee 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 Hong Byung-hee 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 Hong Byung-hee 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 Hong Byung-hee

In research: Hong Byung-hee 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 Hong Byung-hee 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: Hong Byung-hee is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1971 births, Academic staff of Seoul National University, Living people, so understanding it makes those chapters shorter.
In everyday life: Look for Hong Byung-hee 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.
