"Our addiction to oil is the major cause of global warming."
Joongang Daily, one of the major newspapers in Korea, interviewed Professor John Spengler from Harvard University, an internationally renowned scholar in environmental science, who visited Korea for a conference. He mentioned KAIST’s online electric vehicle (OLEV) during the course of interview.
The paper interviewed him on a wide range of environmental issues, and below is a translation of the original Korean article. For the Korean article, please download the attached picture file.
“Our addiction to oil is the major cause of global warming.”
Interview with Professor John Spengler from Harvard University—he is an internationally renowned scholar in environmental science.
By Chan-Soo Kang, Joongang Daily
September 3, 2010
“The oil spill in the Gulf of Mexico by British Petroleum (BP), a multinational oil company, took place against the backdrop of our addition to oil,” said Professor John Spengler (66 years old) from Harvard University on September 2.
“The fact that we are addicted to oil means we are obsessed with mobility as well. Throughout the history of mankind, there has never been the time when we move from one place to another as frequently as today and are dependent on fossil fuels as much as today.”
Visiting Korea to attend a conference co-sponsored by International Society of Exposure Science (ISES) and International Society of Environmental Epidemiology (ISEE) that was held at Coex in Seoul from August 28 to September 2, he gave his speech at plenary talks of the conference on the a topic titled, “Our health is our planet.”
Professor Spengler is an internationally well-known expert in the research of indoor air pollution and environmental exposures of chemical compounds. At the conference, he mostly talked about an ecological catastrophe resulted from the explosion of an oil rig operated by BP in the Gulf of Mexico.
He pointed out,
“It’s been a problem that oil companies are more willing to take risks of exploring dangerous places to obtain oil as the demand for oil has increased. Excessive oil consumption cannot help but lead to global warming.”
“Particularly,” he said, “the unusual climate events, frequently happening in recent years, including severe heat wave and drought in Russia this summer, are somewhat expected to occur by weather forecast models. However, it seems that the extreme weather patterns are taking place more frequently, and accordingly, we are facing more severe effects of weather conditions.”
Professor Spengler emphasized that “We should change our diet and lifestyle to reduce the stress put on our ecosystem, such as getting protein from vegetables rather than from fish or meat and having a habit of curtailing energy consumption.”
“While I’m here, I have a chance to see an online electric vehicle (OLEV) developed by KAIST. If this technology is applied, we can reduce environmental problems as such,” he assessed the development of OLEV.
He also said that “the State of Utah in the US has expressed its intention to adopt the OLEV technology.”
With regard to his research focus on indoor air pollution, Professor Spengler said, “We are having problems like “New House Syndrome” because we try to build a house with cheap materials. Governments should set a standard and control pollutants released from building materials in order to reduce risks resulted from indoor air pollution.”
He argued, “In the early 1990s, when the Irish government introduced an enhanced regulation of air pollution in Dublin, the mortality rate of the city in that winter dropped dramatically.”
“It’s been proven that as fine particle pollution gets worse, more patients with cardiovascular diseases die. Therefore, we need to make efforts to reduce the air pollution.”
“Compared with other nations,” Professor Spengler estimated Korea as a nation that “definitely improved its air quality by introducing buses with a Compressed Natural Gas (CNG) engine to its public transportation system.”

Nanowire crystal transformation method was newly developed by a KAIST research team.

Figure 2

Professor Bongsoo Kim of the Department of Chemistry, KAIST, and his research team succeeded to fabricate Heusler alloy Fe3Si nanowires by a diffusion-driven crystal structure transformation method from paramagnetic FeSi nanowires. This methodology is also applied to Co2Si nanowires in order to obtain metal-rich nanowires (Co) as another evidence of the structural transformation process. The newly developed nanowire crystal transformation method, Professor Kim said, would be valuable as a general method to fabricate metal-rich silicide nanowires that are otherwise difficult to synthesize.
Metal silicide nanowires are potentially useful in a wide array of fields including nao-optics, information technology, biosensors, and medicine. Chemical synthesis of these nanowires, however, is challenging due to the complex phase behavior of silicides.
The metal silicide nanowires are grown on a silicon substrate covered with a thin layer of silicon oxide via a simple chemical vapor deposition (CVD) process using single or multiple source precursors. Alternatively, the nanowires can be grown on the thin silicon oxide film via a chemical vapor transport (CVT) process using solid metal silicide precursors.
The CVT-based method has been highly effective for the syntheses of metal silicide NWs, but changing the composition of metal silicide NWs in a wider range, especially achieving a composition of a metal to silicon, has been quite difficult.
Thus, developing efficient and reliable synthetic methods to adjust flexibly the elemental compositions in metal silicide NWs can be valuable for the fabrication of practical spintronic and neonelectronic devices.
Professor Kim expliained, “The key concept underlying this work is metal-enrichment of metal silicide NWs by thermal diffusion. This conversion method could prove highly valuable, since novel metal-rich silicide NWs that are difficult to synthesize but possess interesting physical properties can be fabricated from other metal silicide NWs.”
The research result was published in Nanao Letters, a leading peer-reviewed journal, and posted online in early August 2010.

An internationally renowned academic journal published the research result produced by a KAST research team on its cover.
Fc DAAP VEGF-Trap

Professor Gou-Young Koh of the Biological Sciences Department, KAIST, and his research team published their research result in Cancer Cell, a peer-review scientific journal, as a cover article dated August 17, 2010. It is the first time for the journal to pick up a paper written by a Korean research team and publish it as the cover.
It has been known that a vascular growth factor (VEGF) is closely related to the growth of a tumor. The research team recently discovered that in addition to VEGF, another growth factor, angiopoietin-2 (Ang2), is also engaged with the increase of tumors.
Professor Koh said, “VEGF and the angiopoietins play critical roles in tumor progression and metastasis, and a single inhibitor targeting both factors have not been available.”
The team led by Professor Koh has developed a double anti-angiogenic protein (DAAP) that can simultaneously bind VEGF-A and the angiopoietins and block their actions.
Professor Koh said in his paper, “DAAP is a highly effective molecule for regressing tumor angiogenesis and metastasis in implanted and spontaneous solid tumor; it can also effectively reduce ascites formation and vascular leakage in an ovarian carcinoma model. Thus, simultaneous blockade of VEGF-A and angiopoietins with DAAP is an effective therapeutic strategy for blocking tumor angiogenesis, metastasis, and vascular leakage.”
So far, cancer patients have received Avastin, anticancer drug, to inhibit VEGF, but the drug has not successfully restrained the growth of cancer tumors and brought to some of the patients with serious side effects instead.
Professor Koh said, “DAAP will be very effective to control the expansion of tumor growth factors, which will open up a new possibility for the development of more helpful cancer medicine with low side effects.”

Nature Photonics, a peer-reviewed scientific journal, released a paper written by a KAIST research team on the time-of-flight measurement.
Professor Seung-Woo Kim of the Mechanical Engineering Department, KAIST, and his research team published the result of their study on the measurement of 1 nanometer (nm) precision.
“The time-of-flight of light pulses has long been used as a direct measure of distance, but state-of-the-art measurement precision using conventional light pulses or microwaves peaks at only several hundreds of micrometers. Here, we improve the time-of-flight precision to the nanometer regime by timing femtosecond pulses through phase-locking control of the pulse repetition rate using the optical cross-correlation technique,” Professor Kim said.
According to the experiment conducted by the research team, “An Allan deviation of 117 nm in measuring a 700m distance in air at a sampling rate of 5 millisecond (ms) once the pulse repetition is phased-locked, which reduces to 7 nm as the averaging time increases to 1 second (s).”
When measuring an object located in a far distance, a laser beam is projected to the object, and the reflected light is analyzed; the light is then converted into an electric signal to calculate the distance. In so doing, Professor Kim said, the conventional method of measurement creates at least 1 mm of deviation.
He argues, “This enhanced capability is maintained at long range without periodic ambiguity, and is well suited to lidar applications. This method could also be applied to future space missions involving formation-flying satellites for synthetic aperture imaging and remote experiments related to general relativity theory."
Nature Photonics published the article online on August 8, 2010.
