[Academics][Researcher of the Month] Opening a New Method to Save the Environment through Discovering a Nanocatalyst

The Department of Materials Science and Chemical Engineering is divided into 5 different sub majors, such as Nano Technology, Bio Technology, Information Technology, and Environment & Energy Technology. Overall, it deals with discovering and creating new materials, which are related to various industries throughout the world. Professor Kim Jong-ho, researching at Hanyang University NanoChemistry Lab at ERICA Campus, has recently discovered a method of substance production and functionalization during his research. Professor Kim uncovered a new method to compose a multifunctional nanocatalyst called PdO@WO₃ and the according substance. PdO@WO₃ has never been reported in the academic world and it also serves a perfect role as both a light photocatalyst and an electrocatalyst. ▲ Professor Kim Jong-ho of the Department of Materials Science and Chemical Engineering of ERICA Campus has recently discovered a method of substance production and functionalization. The material that Professor Kim has discovered is formed through the direct conversion of a PdO nanocluster that has a catalyst function and an ultrathin 2D tungsten oxide (WO₃) nanosheets. This newly found nanosheet serves as a light photocatalyst that converts light energy into chemical energy, while also effectively initiating C-C coupling reactions. PdO@WO₃ can also be used as an electrocatalyst as mentioned above. It is viewed that PdO@WO₃ can be used as a new tool to reduce environmental problems. For example, many medical supplies and medicines such as anticancer drugs go through C-C coupling reactions to be produced. This chain reaction requires a light photocatalyst action of a chemical element called palladium (Pd). The action is usually initiated by mixing palladium into a solution, which makes the material almost impossible to recover after mixing. However, when using the new method created by Professor Kim, the solution becomes a heterogeneous mixture, thus allowing the recovery of the nanomaterial that still maintains the functionality as a catalyst. Palladium is one of the rare-earth materials, known for having a higher price than gold. The ability to use this material again would drop the unit price of the medical supplies and medicines greatly. Moreover, it would also help to improve our natural environment, because the mining of such materials is one of the great factors of environmental destruction. PdO@WO₃ can also be used for creating a next-generation battery to replace the existing lithium-ion battery. The lithium-ion battery has an explosion hazard and low efficiency, which is currently used the most in electronic cars. The demand for the next-generation battery, especially the ones such as the metal-air battery is increasing more than ever. The zinc-air battery that is created through the cathode electrochemical catalyst function of PdO@WO₃ has higher energy density, with no possibility of any explosion hazard. When the zinc-air battery technology becomes commercialized, developing electric cars that can replace cars with an internal combustion engine is expected to become much easier than before. ▲ a) A mimic diagram of C-C coupling reactions conducted using PdO@WO₃ as a light photocatalyst. b) The result of Oxygen Return Reaction conducted using PdO@ WO₃ as the electrocatalyst (Provided by Professor Kim Jong-ho) The discovery of Professor Kim (Thesis title: ‘Ultrathin WO3 Nanosheets Converted from Metallic WS2 Sheets by Spontaneous Formation and Deposition of PdO Nanoclusters for Visible Light-Driven C-C Coupling Reactions') was made possible through the failure of separate research. In the beginning, PdO@WO₃ was simply a byproduct of an experiment with another purpose. However, Professor Kim did not stop after faced with the failure. Instead, he thoroughly analyzed the result and continued various experiments on the newly created material. In the end, Professor Kim redefined the byproduct as a catalyst, after establishing a new method of conversion of the material. Professor Kim stated, “I discovered a new scientific knowledge from the result of an experiment that I thought of as a failure. I also want the students of Hanyang University to not be afraid of the result and to gain new knowledge within it.” The research took a total of two long years; one that ended up with the failed result of the former experiment, the other spent on analyzing and establishing PdO@WO₃. The NanoBio Chemistry Lab of Hanyang University, where Professor Kim's research was done, has continued its studies on creating eco-friendly nanocatalyst material. Professor Kim gained the original patent on the conversion method of PdO@WO₃ and published the work on a scientific journal. He is now considering the publication of how PdO@WO₃ can be applied and used for the metal-air battery. Global News Team global@hanyang.ac.kr

[Performance]Hanyang University Designated as ‘Seoul City Campus Town’, Themed for Start-Up Campus

On December 29th, Hanyang University is newly designated as the ‘Seoul City Campus Town’ project, a start-up support facility in relation to universities. There are 17 newly designated campus towns, including 7 comprehensive types and 10 unit types, and Hanyang University belongs to the unit type university. Hanyang University was elected as it promoted the ‘HY-Seongdong Start-Up Campus’ at the exhibition held by the Seoul City Government. In this exhibition, 31 candidates applied and in-site survey, document review, and presentation followed. Hong Cheol-gi, the head of judges, said, “We considered the capability of forming start-up spaces that are specific and realizable so that they can help the start-ups immediately from 2020, detailed start-up cultivation plans to heighten the success rates and effects that can bring about including regional revitalization.” Campus town is divided into the comprehensive type and the unit type. The comprehensive type is to revitalize housing, cultural, commercial, and regional cooperation, based on the youth start-ups. The unit type is to promote youth activities based on university-specific characteristics and capacities. Previously selected comprehensive types were guaranteed 4 years and 3 years for unit types for the project duration. However, from these new projects, the project will be continued depending on the annual results of each campus town. Hanyang University is funded a maximum of 500 million won since it is selected as the unit type university. It will establish a detailed project plan from January and it will continue for a year.

[Performance]Hanyang alumni established startup ‘n.thing’ awarded with Best Innovation Awards in CES 2020

On the 7th (local time), at the world’s biggest technology show, CES 2020 held in Las Vegas, a farm-tech (agriculture technology) startup n.thing's Plenty Cube was awarded the ‘CES 2020 Best Innovation Awards’ in Smart Cities topic, selected by the American Consumer Technology Association (CTA). It was the only Korean company to be awarded within the Smart City topic. n.thing’s Plenty Cube is a modular farm that grows crops in a 40 feet container. It allows for flexible management in crop variety and supply, depending on the demand. Because it perfectly controls factors such as temperature and nutrition, it allows crops to be harvested as much as 13 times a year. The characteristic of Plenty Cube lies in the fact that it uses a nutrient solution instead of soil. Kim Hyeyeon CEO emphasized that the advantages of Plenty Cube are ‘standardization’ and ‘crop competitiveness’. He explained that Plenty Cube can fast and easily construct and expand the farm complex by connecting the modules, which is differentiated from the existing factory or warehouse styled vertical farms that have large space scale, creating difficulty in area expansion or harvesting more than one crop per farm. Meanwhile, Kim Hyeyeon, the CEO of n.thing, who graduated from Electronic Engineering of Hanyang University ERICA, discovered the possibility of 4th industrial revolution in agriculture within the global market through establishing a joint venture in Uzbekistan with his uncle in 2010, which dealt with a project of setting up a vinyl greenhouse and creating tomato farm. After, he concretized the smart farming technology that can be integrated with agriculture, during the time of participating at an IoT (Internet of Things) platform development project from Korea Electronics Technology Institute in 2012, later establishing n.thing in the January of 2014.

[Academics]Professor Shin Heung-soo’s Team Has Developed a New Stem Cell Delivery Method Inspired from Lotus

Professor Shin Heung-soo Hanyang University announced on the 7th that a team led by Shin Heung-soo, a professor at the Department of Bio Engineering, recently developed a stem cell delivery technology that can more efficiently treat a wide range of wounds caused by burns as such. Professor Shin developed a method that can produce large quantities of ‘stem cell three-dimensional spheroid’, known to be efficient in treating wounds and deliver them evenly to a wide range of areas. The technology is expected to be widely used to treat patients with extensive area wounds such as burns and ulcers when it can be commercialized in the future. Stem cells are being researched to treat various incurable diseases by injecting it into the human body since they possess functions such as self-replication, differentiation possibility into various cells, growth factors, and immunosuppression factor secretion. However, stem cells had the disadvantage of significant decrease in cell function since the environment around the cell differs from the environment in the body when incubating in vitro system and the limitation that local transmission in the human body is possible in the form of an injection, but it cannot regenerate the tissue in a wide area of damage. Professor Shin’s team derived ideas from lotus and solved these problems. He created a biomaterial that small rooms in hundreds of micrometer-scale, formed on a large scale regularly on the surface, to replicate the structure that each seed is fixed inside lotus seedpod. He formed three-dimensional spheroids by making stem cells extracted from human fat tissues to be brought together. Dealing with the process that the fixed seeds inside lotus become released outside due to external forces, he designed the stem cell spheroids formed in each room to be released externally when biological material expands. As a result of animal model testing, the three-dimensional spheroids produced through this process could be transplanted into a wide-range skin wound easily and showed a cure effect that is improved twofold. Professor Shin said, “This research can increase the survival rate of cells transplanted in the human body by refining the delivery method of stem cell treatment that a lot of people are interested in. It is a meaningful original technology to increase the efficiency of cell treatment with a small number of cells.” This work was researched together with Professor Choi Yu-seok of the University of Western Australia and Professor Moon Seong-hwan of Konkuk University College of Medicine, and the result of the research is listed on the December volume of ‘Biomaterials’, the magazine of authority in the biomaterials field. The research was funded by the Mid-sized Research Support Project and Natural Simulation Innovation Technology Development Project of National Research Foundation, Ministry of Science and ICT. ▲ A biomaterial for the stem cell spheroid delivery and production, based on the lotus-simulated biomaterial.

[Policy]“Into the Unlimited Storage,” Hanyang University Officially Introduces G suite for Education

Google Logo Hanyang University officially introduces Google’s G suite for Education (‘G suite’ hereafter) from January 7th, 2020. People can use the official service with the shift of Hanyang mail at 6 PM from the 7th of January. The biggest change lies in email. The previous Hanyang mail was provided within the individual mail service, but it has now shifted to Gmail, which is one of the largest webmail service providers. This has meant the shift to ‘cloud mail.’ Hanyang mail users can have unlimited storage, despite the fact that there was a 15GB limitation for normal users in the past. Therefore, people do not need to worry about emptying mailboxes regularly. If a normal user wants to enlarge their storage, one should pay. Not only storage increases but mobile access was also enhanced via an exclusive app, and one can use other Gmail-based functions. As the security was reinforced, one should manage the password other than the previous HY-in system. This is because one needs to follow Google’s password policy. Two-level authentification is available, utilizing texts as such. The Office of Information and Communications Technology Services introduced the move of email data and limited access to the previous system. Other than email, people can use various services through Google G suite. One can also log-in to Google using Hanyang email accounts. G suite is basically a bundle of various applications that Google is servicing on the web, differentiating the normal users by giving additional access. In particular, unlimited storage is the biggest feature. It is provided in a unified way, which means everything that uses the cloud services are combined altogether. For example, if a normal user used 10GB for mail service, the drive is to be used under 5 GB limitation if he or she is using a 15GB plan. The G suite service offered to universities is ostensibly ‘unlimited,’ and there is no significant limitation in the sharing of storage among different services. However, Google’s detailed guidelines state that the combined capacity is up to 5 TB (reference: 1 TB = 1024 GB), so it appears to be almost unlimited for ordinary users. However, the maximum storage limit should be kept in mind. Google’s G suite services allow users to back up or share files and photos in the cloud (Google Drive and Google Photos), create documents through an online office (Docs, Spreadsheets, Slides), and create online questionnaire forms or manage online memory. It supports communication from voice to video chat, and not only personal work but also teamwork collaboration or mobile linkage can be provided through calendars and address books. In addition to personal learning support for students, it is expected to be used in a variety of ways, including administrative and research support. In addition, it is expected to use various functions with the support of the Office of Information and Communications Technology Services. Regarding the introduction of G suite, the Office of Information and Communications Technology Services announced its intention to respond to the continuous security accidents and threats of Hanyang Mail and to support the implementation of the strategy for developing education, research and administration of members through an online collaboration platform, along with reducing the cost of system operation. For additional information regarding the introduction of the Hanyang University G suite, please refer to the official information page at https://gsuite.hanyang.ac.kr. ▲ Introducing G suite: from the web page of the Office of Information and Communications Technology Services Global News Team Translated by: Lee Seong-chae global@hanyang.ac.kr
