Super-Fast Internet Data Chip Developed
A KAIST research team led by Prof. Kyoung-Hoon Yang of the Electrical Engineering & Computer Science Department developed a super-fast chip that could lead to huge advancements in broadband Internet technology, the Korean Ministry of Education, Science and Technology said on Thursday (June 26).
The multiplexer chip is the first of its kind to be developed using the quantum effect of resonant tunnelling diode, according to the Ministry.
The integrated circuit chip built at the university laboratory has an operating speed of 45 gigabits per second (Gb/s), while using roughly 75 percent less energy than the previous version. The speed enables the transfer of about 4 full-length movies in one second.
The best operational broadband Internet services provide users with data transfer speed of 40 Gb/s, while most other high-speed online connections offer 10 Gb/s.
"Besides speed, the greatest achievement is low energy use," Prof. Yang said. He stressed that energy use in chips is a crucial factor because power creates heat that can melt circuits and make them inoperable.
"By cutting down on energy use, the new chips can be made smaller and with faster data transfer speed," the scientist said.
He added that efforts are underway to increase operational speed to 100 Gb/s, with energy consumption to be cut to 10 percent of current chips like the high electron mobility transistor, the heterojunction bipolar transistor and the complementary metal oxide semiconductor.
The researcher speculated that such revolutionary chips could be developed in 1-2 years and become the new benchmark in this field since existing chips have limited development capabilities.
The project has received funding from the Education-Science-Technology Ministry since 2000. The Ministry"s financial support will last until 2010.

New System to Generate Extreme-Ultraviolet Light Developed
A KAIST research team led by Prof. Seung-Woo Kim of the Mechanical Engineering Department developed a new system for generating coherent extreme-ultraviolet (EUV) light, school authorities announced on June 5.
The new system comes in a metallic nano-structure consisting of a two-dimensional array of gold "bow tie" elements on a sapphire plate. The new process was featured in the British journal Nature on June 5.
The properties of coherent EUV light make it a prime candidate for exciting technological applications. But, at present, the equipment needed to generate the short-wavelength light is costly and bulky. The system developed by Prof. Kim"s research team is expected to reduce both cost and bulk.
The new system uses the conventional principle of high-harmonic generation via the interaction of a femtosecond laser pulse with a gas, but adopts the novel concept of amplifying light by way of local plasmon field enhancement, according to the research team.

KAIST, GS Caltex Jointly Develop New Bacteria to Produce Biobutanol
KAIST and GS Caltex, Korea"s second-largest refiner, have jointly developed a new strain of bacteria to produce biobutanol, which is regarded as a promising next-generation biofuel, KAIST authorities said on Monday (June 2).
A research team led by Prof. Sang-Yup Lee of the Chemical and Biomolecular Engineering Department and researchers of GS Caltex succeeded in developing an improved strain of bacteria which enables to produce a large amount of biobutanol in the process of fermenting biomass. The research team has applied for international patent for the new technology.
Biomass refers to living and recently dead biological material that can be used as fuel or for industrial production. It usually refers to plant matter grown for use as biofuel, but it also includes plant or animal matter used for production of fibers, chemicals or heat.
In the 1970s and 1980s when scientists began researching the possibilities of alternative fuels, bacteria were used in the process of fermenting biomass. This ABE (acetone, butanol, ethanol) fermentation process yields butanol, acetone, and ethanol in a ratio of 6:3:1, respectively. Acetone produced in this process is not usable.
The newly developed technology to produce biobutanol has an advantage of lowering production cost by eliminating the process to separate acetone from butanol. This has been made possible by improving the bacteria used for the fermentation in metabolic engineering terms, and producing butanol and ethanol only in a ratio of 6:1, while curbing the generation of acetone.
In comparison with bioethanol, also a biofuel mixture which is currently under widespread use in some countries, butanol is more easily transported with gasoline and diesel through pipelines because of its lower tendency to separate from the fuel when contaminated with water. Butanol is also less corrosive than ethanol, another reason its transport through pipeline is preferable.
Global interest in full utilization of biomass and development of other alternative energy including biobutanol has deepened in recent years, as crude oil prices have skyrocketed to record levels and climate changes resulting from the excessive use of fossil fuel have been causing various problems around the world.

KAIST, ICU Agree to Merge
KAIST and the Information and Communications University, a state-run institution, decided to merge as they signed a memorandum of understanding for unification at the Westin Chosun Hotel in Seoul on May 23.
The MOU signing ceremony was attended by representatives of the two universities and related high-ranking government officials from the Ministry of Knowledge Economy and the Ministry of Education, Science and Technology.
Under the agreement, the two universities will form a joint committee to complete the merger process by the end of this year. According to the MOU, ICU will become the "IT Convergence Campus" (ICC) which will include KAIST"s IT related departments and research institutes. The projected ICC will be headed by a KAIST vice president, KAIST authorities said.
With the merger, the number of KAIST students in the IT area will increase to 2,850 from 1,951, while the number of IT-related faculty members will rise to 157 from 99.
ICU was established in 1997 by the Korean Ministry of Information and Communication, the Electronics and Telecommunications Research Institute, and some major Korean IT companies. Located in Daedeok Science Town in Daejeon where KAIST is also situated, ICU started as a graduate school and added the undergraduate course in 2002. It currently has a total enrollment of 1,121 students -- 481undergraduate students, 324 graduate students and 316 doctorate students.
KAIST said that it will treat ICU professors and staff equally after the merger. This year, the two universities will separately conduct freshmen recruitment procedures for 2009, but will then unify recruitment.
The unification of the two institutions is expected to give KAIST the competitive edge through a larger faculty, student body, and expanded facilities.
The agreement put an end to extended negotiations for merger which started in July 2006. The talk of merging the two universities surfaced when the Board of Audit and Inspection concluded that the government"s direct financial support for ICU was unlawful as ICU was established as a private school. When ICU was established in 1997, the Ministry of Information and Communication provided 200 billion won as the basic endowment and has continually provided 10 billion won in operating funds each year.
