Hong Byung-hee 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. [1]
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 GSI have invented an industry compatible growth (CVD) and transfer (Roll-to-Roll) process enabling the large scale synthesize of graphene for commercial applications. [2] The related key patents have been registered in Korea, US, Japan, and China.
Hong is also the founder of GSI 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 [3] 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.
A carbon nanotube (CNT) is a tube made of carbon with a diameter in the nanometer range (nanoscale). They are one of the allotropes of carbon.
Nanotechnology, often shortened to nanotech, is the use of matter on atomic, molecular, and supramolecular scales for industrial purposes. The earliest, widespread description of nanotechnology referred to the particular technological goal of precisely manipulating atoms and molecules for fabrication of macroscale products, also now referred to as molecular nanotechnology. A more generalized description of nanotechnology was subsequently established by the National Nanotechnology Initiative, which defined nanotechnology as the manipulation of matter with at least one dimension sized from 1 to 100 nanometers (nm). This definition reflects the fact that quantum mechanical effects are important at this quantum-realm scale, and so the definition shifted from a particular technological goal to a research category inclusive of all types of research and technologies that deal with the special properties of matter which occur below the given size threshold. It is therefore common to see the plural form "nanotechnologies" as well as "nanoscale technologies" to refer to the broad range of research and applications whose common trait is size.
Graphene is an allotrope of carbon consisting of a single layer of atoms arranged in a hexagonal lattice nanostructure. The name is derived from "graphite" and the suffix -ene, reflecting the fact that the graphite allotrope of carbon contains numerous double bonds.

Buckypaper is a thin sheet made from an aggregate of carbon nanotubes or carbon nanotube grid paper. The nanotubes are approximately 50,000 times thinner than a human hair. Originally, it was fabricated as a way to handle carbon nanotubes, but it is also being studied and developed into applications by several research groups, showing promise as vehicle armor, personal armor, and next-generation electronics and displays.
Charles M. Lieber is an American chemist, a pioneer in nanoscience and nanotechnology, and a convicted felon.

Nanobatteries are fabricated batteries employing technology at the nanoscale, particles that measure less than 100 nanometers or 10−7 meters. These batteries may be nano in size or may use nanotechnology in a macro scale battery. Nanoscale batteries can be combined to function as a macrobattery such as within a nanopore battery.
The nanoscopic scale usually refers to structures with a length scale applicable to nanotechnology, usually cited as 1–100 nanometers (nm). A nanometer is a billionth of a meter. The nanoscopic scale is a lower bound to the mesoscopic scale for most solids.

Techniques have been developed to produce carbon nanotubes in sizable quantities, including arc discharge, laser ablation, high-pressure carbon monoxide disproportionation, and chemical vapor deposition (CVD). Most of these processes take place in a vacuum or with process gases. CVD growth of CNTs can occur in vacuum or at atmospheric pressure. Large quantities of nanotubes can be synthesized by these methods; advances in catalysis and continuous growth are making CNTs more commercially viable.
