A domestic research team developed an energy generation system using the flutters of flags.  On the 24th, SNU revealed that Professor Ho Young Kim from the Mechanical and Aerospace Engineering department used the flag flutters to develop an energy harvesting system.
 
The energy harvesting system uses the effect of friction to bring high energy generation to small places.  Because it only uses one board, ti is cheap and does not produce lots of noise or environmental pollution.
 
Professor Kim stated, “Wireless, portable, and wearable energy-using systems can use this system and will be used for more developments.”
 
Professor Kim first used gold coated electricity products to make flags and installed conducting film plates near the flags.  Due to the wind, the flag will flutter and when it conducts with the plate installed near the flag, it will produce electricity.  This process can charge small batteries and other small items.

Through these systems, small products can be charged electrically and if several flags are installed, they can charge larger devices.  If the flags are installed on fast-travelling cars or walls, lots of energy can be produced.
 
Professor Kim stated, ‘This energy harvesting system increases efficiency and can be used in sensor network, micro electricity devices and can be relevant to currently developed devices.  We will continue to improve this process in future research.”
 
This research was conducted with funding from the Ministry of Education’s Global Frontier and Research Project.  Involved in the research were Dr. Ji Hyun Bae from Samsung Electronics, Ph.D Candidate Jung Soo Lee from SNU, and Professor Jong Jin Park from Jeon Nam University.  The paper was published in the September 23 issue of “Nature Communications.”

On the 22nd, it was revealed that Seoul National University Materials Engineering Professor Ki Suk Kang’s team published a paper in the “Chemical Reviews” on rechargeable batteries.
 
This research received funding from the Ministry of Trade, Industry, and Energy and the Korea Institute of Energy Technology Evaluation and Planning’s “Get-Future Energy Project.” The research was conducted by Professor Kang’s research team of Ph.D candidate Hae Kyum Kim, Ph.D candidate Ji Hyun Hong, Ph.D candidate Kyu Young Park, Ph.D candidate Hyoung Sup Kim, and Korea Atomic Energy Research Institute Dr. Sung Wook Kim.
 
Currently, most rechargeable lithium energy batteries are carbonate-based organic liquid electrolytes.  The organic liquid electrolytes are highly flammable, so have a high chance of exploding.  Lithium ions also have low conductivity, so developing high-energy rechargeable batteries was difficult.
 
However, Professor Kang’s team used water as an electrolyte to solve the problems involved in the aqueous electrolyte-based rechargeable batteries.  There is no risk of flammability or toxicity and lithium ion has high conductivity and is cheap.
 
Professor Kang stated, “This rechargeable battery is eco-friendly and very adaptable to next-generation energy systems. Eco-friendly batteries are not that far from becoming a reality and there will be lots of research into this area in the future.”
 
This research is important in the chemical industry, and was included in the Chemical Reviews as “Aqueous Rechargeable Li and Na Ion Batteries.”  This paper combines research into lithium rechargeable batteries, sodium rechargeable batteries, magnesium electricity, etc.
 
This information was in the online issue released September 11 (Thursday) and will be in the upcoming December Special Issue: Batteries.  It has been 10 years since 2004 when Chemical Reviews published a special issue on batteries.

A local research group developed a transparent and elastic electrode material that is required for wearable electronic devices.  SNU Mechanical and Aerospace Engineering Professor Seung Hwan Go and his research team (MIT Researcher Philip Lee, KAIST Researcher Joo Yeon Ham, KAIST Researcher Jin Hwang Lee) developed this transparent silver nanowire and carbon nanotube composite material.
 
Originally, Indium Tin Oxide (ITO) was used since it has good conductivity and transparency, but the cost was unstable and had bad flexibility so there were limits to use in wearable devices. This composite material is able to overcome these limitations.
 
Using the pressure difference of a vacuum pump, it can place carbon nanotube walls and nanowire walls on top of a filter to put a flexible substrate on top.  The composite material is made as if there is a stamp to maintain security and conductivity.
 
This electrode material is similar to the ITO in that it has great transparency and conductivity, but it has better flexibility.  Even after 10,000 folds or being stretched to four times its length, it maintains conductivity.
 
Professor Go stated, “This research used a free patterning manufacturing method to come up with a composite of nanowire and carbon nanotubes. This new electrode material will not have any problems when used for wearable devices.”
 
The research team is planning to use this composite material on devices that use touchscreen. This research was published in the July edition of Advanced Functional Materials as a very important and urgent paper (Paper name: Highly stretchable or transparent conductor fabrication by hierarchical multi-scale hybrid nanocomposite).

A domestic research group solved the difficult cell membrane transformation process.  From this, they are able to come up with new ways to treat specific protein binding, drug delivery, and signal transmission.
 
This research was conducted in collaboration between Seoul National University’s Electrical and Information Engineering Professors Shin Doo Lee, Byung Ho Lee, and Young Sang Yoo with the University of Minnesota Biomedical Engineering Professor Sang Hyun Oh. They looked at the mother child cell pairings to find how the cholesterol, lipids, and proteins stick to surfaces.

The research team looked at the nano pattern process to see how the lipid raft used signals. This type of research had not been done before, so the joint research team was able to come up with this new method of demonstrating functional groups in the membrane. The industry has proclaimed that this research will be used in new drug production and treatment of patients with various diseases.
 
SNU Professor Shin Doo Lee stated, “cell membrane shape and location will help us learn how they signal. Particular modifications in proteins will allow us to determine the causes of Alzheimer’s or Parkinson’s diseases.”
 
This research was funded by the Korean Research Fund from the Ministry of Science, ICT, and Future Planning (No. 2007-0054847). This research has been published in the online edition of “Nature Communication” on the 24th.
