A domestic research group revealed that they developed a long-life, high-output, and environmentally-friendly rechargeable lithium battery.
 
Seoul National University’s Department of Materials Science and Engineering Professor Ki Suk Kang (image, left) and KAIST Department of Materials Science and Engineering Professor Chan Bum Park (image, right) worked together to develop a next-generational rechargeable lithium battery.  Their work was published in the Nature Communications journal.
 
Until now, high-energy and high-output rechargeable lithium batteries used transitional metals (cobalt, manganese, nickel, iron, etc) for the electrodes.  However, transitional metals increase the weight of the battery so places limitations on the amount of energy each battery can hold.  It also has problems in manufacturing and recycling that make it hard to be environmentally-friendly.  The research team decided to use bio-derived materials to solve these problems.
 
The research team discovered this bio-derived material last year for use in rechargeable lithium batteries and began researching it in earnest since then.  During cell respiration, the mitochondria produces flavin adenine dinucleotide (FAD), which is used in sending information and can provide energy through the process.
 
The research came up with an easier process that would complete the same type of action.  Within the cell, the lithium saves energy in what is called the redox center.  They get rid of unnecessary processes until only the bare minimum electrode material that is needed can stay.  Through this, they are able to improve the rechargeable battery’s effect.  This process can allow the battery to recharge at least 500 times while still maintaining at least 95% of the total battery capacity.  The bio-derived material will allow the rechargeable lithium battery to maintain most of its capacity throughout its life as opposed to the currently utilized batteries that diminish capacity greatly. 
 
Professor Ki Suk Kang stated, “Various bio-derived materials can be used to improve the capacity of the rechargeable battery.  This shows that there can possibly be a biological battery developed in the future.”  This research was conducted as a joint research between biological materials and lithium battery areas, and will help develop much needed improvements into the battery field.
 
This research was supported by the Agency for Defense Development and conducted by Seoul National University Professor Ki Suk Kang and KAIST Professor Chan Bum Park with students Ji Hyun Hong and Min Ah Lee.  This was published online on Nature Communications on October 31.

Seoul National University’s Department of Naval Architecture and ocean Engineering Professor Jong Gye Shin won the Best Paper Award from the American Society of Naval Architects.  Professor Jong Gye Shin worked with Researcher Jung Seo Park from Samsung Heavy Industries, Advisor Jae Hoon Kim, Manager Dae Kyung Kim, and Professor Gwang Hee Go from Gwangju Institute of Science and Technology to win the 2014 Elmer L. Hann Award for their paper “Automatic Heat Processing Equipment for Triangular Heating.”
 
The award has been awarded annually since 1991 and is given to the best research paper on naval ship production.  For a non-American group to win the award is already exceptional, but Professor Jong Gye Shin is even more unusual in that he already won the award once back in 2001.  Until now, there have only been 3 people who have won the Elmer L. Hann award more than once and Professor Jong Gye Shin is the only one in Korea.
 
Professor Jong Gye Shin’s research team was the first to develop a high frequency induction heating equipment that uses an algorithm to decide on the workplace location and speed.  This current research was successful for surfacing a ship for use in Samsung Heavy Industries.  It can automate the process to be more efficient.
 
This was the first research in the naval industry to completely automate the process.  The ships front and back have curved surfaces.  Until now, only those with more than 15 years’ experience have surfaced the area utilizing their skills.  However, the work results in not only loud sounds, but also in minor differences since it is done by an individual person.  There has been research into allowing automation of simple surfaces, but not for those with circular surfaces like those of a ball.  Because of the difficulties inherent with automating a circular surface, this research was unprecedented in nature.
 
The results from the research were used in actual industry and was very practical in its use. Samsung Heavy Industries stated that they saw improvements in the results after utilizing the automation system.  Professor Jong Gye Shin stated, “This surfacing automation is one of the most important breakthroughs in this industry.  Seoul National University and Samsung Heavy Industries is being praised globally for this skill.”

Seoul National University’s Mechanical and Aerospace Engineering Professor Byung Dong Yoon’s research team won the PHM Society’s 2014 PHM Data Challenge Competition in the Prognostics and Health Management (PHM) area.  Professor Yoon’s team went to Fort Worth, Texas in September 29 to October 2 at the 2014 PHM ceremony.
 
This year’s PHM Data Challenge Competition analyzes the big data from engineering system and assesses the possible the damage from the system.  This challenge used data from General Electric (GE).  Dr. Dustin Garvey produced the problem by stating, “I made the problem to be as difficult as possible for the participants.”  Professor Yoon’s team used the data to analyze the part lifespan calculation and usage calculation.  In addition, the ensemble was used to effectively assess system damage.
 
The PHM Data Challenge Competition is held together by the PHM Society and IEEE Reliability Society.  Professor Yoon’s research team won the Data Challenge Competition from the IEEE Reliability Society as the first Asian winner and became the winner of the PHM Society’s Data Challenge Competition.  Until last year, all the winners were only from the United States and Europe.  The fact that Professor Yoon’s team won both awards in the PHM sector has the biggest meaning in the global arena.
 
This ceremony’s topic was on the hot issue IoT to analyze big data.  Until now, big data accumulation has made it difficult to analyze all the information. This will help the engineering system analyze the big data and to figure out problems that occur unexpectedly.  Professor Yoon has currently been developing technology in O&M management and manufacturing.  It is expected to have considerable influence in the industry.

▲ Naval Architecture for Non Naval Architects” published in September


Professor Emeritus Hyo Chul Kim and Professor Shin Hyoung Lee published “Naval Architecture for Non Naval Architects.”  They are highly skilled domestically in naval engineering.
 
Currently, the movie “Myoung Ryang” has received considerable acclaim.  However, this book addresses the idea that perhaps the movie would have been more interesting if they went more in depth into the boat structure and characteristics.

 

In reality, for a Japanese boat to travel considerably fast, they were built small and had a V shape on the bottom side.  On the other hand, the Korean boats were made with thick base and the bottom of the boat was flat to make it stable to gun fires and direction changes.  Additionally, General Soon Shin Lee’s boat HakIkJin used the crane’s wings to travel fast.
 
Therefore, when the characteristics are known, the data is more interesting.  In this book, the boat’s hidden stories and characteristics are known. 
 
Author Harry Banford taught at Michigan State University and has been involved in Naval Engineering and is currently an emeritus. While he was writing this book, he stated “Because civilizations developed with the water, boats were very important.  I hope the general public will be able to understand boats and I hope current students will show more interest in this area.”
 
Professors Shin Hyoung Lee and Hyo Chul Kim stated, “Science and art come together in a very good combination in this area.”  This means that in the future engineering and science must keep an artistic mind to develop.

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.”
