The control of light at the nano-level
Professor Min Bumki Professor Min Bumki’s research team from the Department of Mechanical Engineering at KAIST have successfully gained control of the transmittance of light in optical devices using graphene* and artificial 2-dimensional metamaterials**. * Graphene : a thin membrane composed of pure carbon, with atoms arranged in a regular hexagonal pattern ** Metamaterials : artificial materials engineered to have properties that may not be found in nature The research results were published in the recent online edition (September 30th) of Nature Materials, a sister journal of the world renowned Nature journal, under the title ‘Terahertz waves with gate-controlled active graphene metamaterials’ Since the discovery of graphene in 2004 by Professors Novoselov and Geim from the University of Manchester (2010 Nobel Prize winners in Physics), it has been dubbed “the dream material” because of its outstanding physical properties. Graphene has been especially praised for its ability to absorb approximately 2.3% of near infrared and visible rays due to its characteristic electron structure. This property allows graphene to be used as a transparent electrode, which is a vital electrical component used in touch screens and solar batteries. However, graphene’s optical transmittance was largely ignored by researchers due to its limited control using electrical methods and its small optical modulation in data transfer. Professor Min’s team combined 0.34 nanometer-thick graphene with metamaterials to allow a more effective control of light transmittance and greater optical modulation. This graphene metamaterial can be integrated in to a thin and flexible macromolecule substrate which allows the control of transmittance using electric signals. This research experimentally showed that graphene metamaterials can not only effective control optical transmittance, but can also be used in graphene optical memory devices using electrical hysteresis. Professor Min said that “this research allows the effective control of light at the nanometer level” and that “this research will help in the development of microscopic optical modulators or memory disks”. figure 1.

Commercialization of Carbon Capture and Storage Technology Speeds up
KAIST research team successfully developed the ideal method for carbon dioxide transportation, which is crucial in the capturing and underground storage of carbon dioxide technology. Professor Jang Dae Joon of the department of Ocean Systems Engineering developed a carbon dioxide transportation that minimizes evaporative gases. The new technology is the final piece of the three part carbon capture storage which involves capture, transportation, and storage of carbon dioxide. The completion of the three part technology will allow for commercialization in the near future. Carbon Capture and Storage technology is regarded as the technology that will reduce carbon dioxide levels. It captures the carbon dioxide emitted from power plants and factories and storing them permanently in empty oil fields underground. If the post Kyoto Protocol was to be implemented from 2013, Korea will not be able to shirk from the need to reduce carbon emissions. Therefore the Korean government set out to reduce 32 million tons of carbon dioxide (10% of predicted carbon reduction) until 2030. In response to the government’s efforts to reduce carbon dioxide emissions, Korean research teams like KAIST have responded. Professor Jang’s team succeeded in developing the core technology for underground storage in the 2009 ‘Carbon dioxide Transport and Injection Terminal Project’. And as the final piece of the puzzle the team developed an optimization solution that addressed the evaporating gases emitted from carbon dioxide during transportation. Professor Jang’s team focused on the required low temperature and high pressure conditions in liquid carbon dioxide transport. The problem lies in the temperature gradient which can cause the transport canister to explode. The solution developed by the team is to evaporate carbon dioxide in a pressurized contained which is then re-liquidated. External variables like price of oil, carbon taxation, etc. have been considered and the process was optimized accordingly. The result of Professor Jang’s team’s solution to Carbon Capture and Storage was stored in the online edition of International Journal of Greenhouse Gas Control.

New wireless charging device developed
The On-line Electric Vehicle (OLEV) developed by KAIST has made a step towards commercialization with the development of a more economic wireless charging device. Professor Chun-Taek Rim from the Department of Nuclear and Quantum Engineering at KAIST has developed a new I-shaped wireless charging device that differs from the pre-existing rail-type electricity feeder. This device can be modularly produced and requires relatively less construction, significantly reducing the cost of implementation. The KAIST OLEV is a new concept electric car that has a special electricity collecting device underneath it. The car’s battery is charged by magnetic fields produced from electric lines buried 15cm underneath the road. The vehicle was first tested in 2009, making it the first wireless electric car in the world. OLEV can be charged during stoppage time between traffic lights and receives real-time power when running. OLEV is currently in operation at the KAIST Munji Campus in Daejeon and is also being exhibited at the Yeosu Expo and Seoul Grand Park. The device itself has a charging capacity of 15kW, and the electricity is supplied through an electricity feeder with a width of 80cm with a space interval of 20cm. Despite being hailed as a technological breakthrough and revolutionary concept, KAIST OLEV has been criticized for problems in commercialization, due to the difficulties in installing wires beneath existing roads, which costs a considerable amount of money. The new I-shaped wireless charging device reduces the width of the electricity feeder by 10cm, a mere one-eighth of the size of the previous version, and greatly increases the charging power to 25kW. Furthermore, the left and right permissible space of automobiles has increased to 24cm and the magnetic field complies with the international design guidelines, making the OLEV safe for the human body. The reduction of the width has made the mass production of modules possible, making the installation of KAIST OLEV more economical and marketable. Professor Rim emphasized that compared with the existing rail-type electricity feeder, the new technology will need only one-tenth of the construction time and 80% of the cost, significantly improving OLEV’s constructability and workability. The research was published in the IEEE Transactions on Power Electronics last December, and Professor Rim was invited to talk at the Conference on Electric Roads & Vehicles, which was held in February in the United States, about the new technology.

KAIST Successfully Demonstrates Mobile Harbor in the Open Sea
Busan, South Korea—Large container ships are no longer required to come into ports to transport cargo, as KAIST has developed an innovative technology that will transform the paradigm of today’s cargo handling operations. A Mobile Harbor is a vessel that carries a large stabilized crane with a smart spreader and multistage trolley system, enabling the loading and unloading of ship cargo on the wavy open sea. Following a successful docking of two vessels at sea in April of this year, KAIST conducted a full scope of Mobile Harbor operations in the inner sea of Busan, South Korea, on June 29, 2011. Initiated in 2009, the Mobile Harbor (MH) is one of the university’s flagship research projects, which aims to provide a new growth engine that will lead the Korean economy to the next level of advancement, and to develop green technology through multidisciplinary and convergence research. The idea of MH came to light when thinking outside the box (why can’t a harbor go out to meet a ship on voyage and retrieve goods instead of ships coming into the harbor?) to improve problems relating to the current maritime transport system, such as port congestion, environmental issues caused by heavy sea transport, increased demand for supersized container ships, and the need for port construction and expansion. The essential technology to establish a Mobile Harbor is a docking system and crane system that can overcome the obstacles imposed by the sea, i.e., waves and wind. Connecting two operating vessels of different sizes in the unpredictable and ever-changing environment of the sea was regarded as “impossible” and had never been tried before, but, on April 26, 2011, KAIST successfully demonstrated the technology to moor vessels safely and securely. The Mobile Harbor has a unique way of mooring vessels that are anchored at sea: its flexibly designed robot arms with a square-shape vacuum suction pad at the tip reach out and attach to the hull of a container ship for docking. Each robot arm is connected to a cable and winch that further add stability to the Mobile Harbor. Foam-filled fenders are placed between the Mobile Harbor and the container ship, thereby maintaining a safe distance to prevent collisions. The crane system consists of a multistage trolley, smart spreader, and tension controller, all of which provide the crane with functionality and stability to move around cargo containers in the sea. The crane system also has various sensors like cameras and laser scanners, and therefore, it can gauge the movement of the spreader and ships as well as trace a target container in real time. As a result, the spreader, a container grabbing device, is free from the swing motions when lifting and putting down cargo and grabs a target container safely in the wavy open sea. During today’s at-sea demonstration in Busan, a research team from the KAIST Mobile Harbor Center docked a Mobile Harbor (a barge ship) right next to a container vessel (the other barge ship) and repeated freight transport operations between the two ships, presenting the great potential to commercialize the Mobile Harbor technology. The project has been implemented in collaboration with industries, research institutes, and universities in such fields as mechanical engineering, robotics, automation engineering, and ocean systems engineering. The demonstration proceeded with a wide range of participants including researchers, engineers, government officials, and entrepreneurs from Korea and around the world. Byung-Man Kwak, Director of the KAIST Mobile Harbor Center, explained his feelings on the successful demonstration: “It’s been a remarkable journey to develop a Mobile Harbor from scratch, and I’m genuinely thrilled to showcase what we have accomplished so far. Today’s demonstration of Mobile Harbor’s core technologies will really change the face of our maritime transportation system. We will be able to deliver more goods to global markets and consumers via sea route, not necessarily building more ports or expanding the existing harbors. KAIST’s Mobile Harbor will also significantly cut down the high cost related to overland transportation of cargo and in return, contribute to the reduction of carbon emission.” The Center has received much interest in possible market migration and broader application of the Mobile Harbor from businesses and organizations, e.g., US Office of Naval Research, King Fahd University of Petroleum and Minerals, Saudi Aramco, POSCO, and the Korean Navy.

From Pencil Lead to Batteries: the Unlimited Transformation of Carbon
Those materials, like lead or diamond, made completely up of Carbon are being used in numerous ways as materials or parts. Especially with the discovery of carbon nanotubes, graphemes, and other carbon based materials in nanoscale, the carbon based materials are receiving a lot of interest in both fields of research and industry. The carbon nanotubes and graphemes are considered as the ‘dream material’ and have a structure of a cross section of a bee hive. Such structure allows the material to have strength higher than that of a diamond and still be able to bend, be transparent and also conduct electricity. However the problem up till now was that these carbon structures appeared in layers and in bunches and were therefore hard to separate to individual layers or tubes. Professor Kim Sang Wook’s research team developed the technology that can assemble the grapheme and carbon nanotubes in a three dimensional manner. The team was able to assemble the grapheme ad carbon nanotubes in an entirely new three dimensional structure. In addition, the team was able to efficiently extract single layered grapheme from cheap pencil lead. Professor Kim is scheduled to give a guest lecture in the “Materials Research Society” in San Francisco and the paper was published in ‘Advanced Functional Materials’ magazine as an ‘Invited Feature Article’.
