- SKKU held the 6th Sungkyun Writing Contest in Vietnam
- SKKU held the 6th Sungkyun Writing Contest in Vietnam SKKU held ‘The 6th Sungkyun Writing Contest’ at Edenstar Saigon Hotel located in Ho Chi Minh, Vietnam on April 25th, where 80 students from 4 countries (Vietnam, Thailand, Laos, and Cambodia) in the region participated. While the students came from different nationalities, they all showed passion and love toward the Korean language. The Korean wave is sweeping accross Vietnam these days. Since 2016, middle and high schools have chosen Korean as a second language course. Professor Tran Van Tu from Van Hien University, who attended the 1st writing contest five years ago as a student, also participated this time with his 6 students. “It feels new to join the event as a professor this time,” said Prof. Tu. The subject of the writing was ‘reconciliation.’ The gold prize went to Tran Nguyen Minh Thu from University of Social Sciences and Humanities at Vietnam National University Ho Chi Minh City. In her writing, she said, “In high school, I saw some friends were getting into arguments over minor things and couldn’t find a solution to get along again. The most important thing for reconciliation is a true heart.” The silver and bronze prizes went to Luong Vu Nguyet Ha from University of Social Sciences and Humanities at Vietnam National University Ho Chi Minh City, and Tran Tung Ngoc from Ha Noi University of Sciences and Humanities, respectively. SKKU will confer scholarships to those students who received the awards. SKKU holds Sungkyun Writing Contests every year in various regions such as China, Middle East, Europe, and Southeast Asia. The Vice President of the Office of International Affairs said, “We had received a lot of interest in the Sungkyun Writing Contest from students in Southeast Asia, so we doubled up the number of participants this year.” University College

- Prof. Yong Taik LIM Develops Implantation of Synthetic Immune Niche that Prevents Tumor Recurrance
- Prof. Yong Taik LIM Develops Implantation of Synthetic Immune Niche that Prevents Tumor Recurrance Cancer vaccines are an attractive option for improving disease-free survival following surgical resection of solid tumors. However, several clinical studies have shown that while cancer vaccines can routinely induce protection in a prophylactic model, the same vaccines often show only limited therapeutic efficacy. The tumor immunosuppressive network, formed by interactions between cancer cells and host immune cells, is a major obstacle to achieving complete tumor eradication. Myeloid-derived suppressor cells (MDSCs) can be considered critical players in tumor-induced immunosuppression in both animal models and cancer patients, which they have a remarkable ability to suppress the activation and proliferation of T cells. Therefore, the depletion of MDSCs would strengthen immunity of tumor-bearing mice. Recently, Prof. Yong Taik LIM’s group of Sungkyunkwan University reported a novel implantable, engineered 3-dimensional porous scaffolds which were designed to generate synergistic action between MDSC-depleting agents and cancer vaccines consisting of whole tumor lysates and nanogel-based adjuvants. The local peritumoral implantation of the synthetic immune niche (termed immuneCare-DISC, iCD) as a post-surgical treatment in an advanced-stage primary 4T1 breast tumor model generated systemic anti-tumor immunity and prevented tumor recurrence at the surgical site as well as the migration of residual tumor cells into the lungs, resulting in 100% survival. These therapeutic outcomes were achieved through the inhibition of immunosuppressive MDSCs in tumors and spleens by releasing gemcitabine and recruitment/activation of dendritic cells, enhanced population of CD4+ and CD8+ T cells, and increased IFN-γ production by cancer vaccines from the iCD. This combined spatiotemporal modulation of tumor-derived immunosuppression and vaccine-induced immune stimulation through the iCD is expected to provide an immune niche for preventing of postoperative tumor recurrence and metastasis.

- Prof. Won Sub YOON develops high-performance battery that can travel up to 400km with one charge
- Prof. Won Sub YOON develops high-performance battery that can travel up to 400km with one charge A research team led by Prof. Won-Sub YOON, Department of Energy Science (DOES) at Sungkyunkwan University, has lifted the fundamental restriction on the breaking point of the lattice and unraveled the enigma of nickel effect on layered cathode materials that has existed for decades in the battery field. Consequently, they discovered the possibility of developing a high-performance battery which can travel up to 400km by one charge. While the technology of lithium ion batteries has been greatly successful since its advent in powering portable electronic devices, further advancements are insatiably demanding for wider applications such as in electric vehicles and grid-power storages. One of the key areas in these efforts is development of new positive electrode ‘cathode’ materials with higher energy densities to replace the lithium cobalt oxide that is currently prevailing as the cathode material. The research is very focused on increasing the amount of Li-ions ‘inserted’ in the electrode material, which affects the charge storage capacity, the speed of Li-ion movement within the crystal lattice of the electrode material, which affects the battery power, and the structural stability of the material upon in-and-out transport of Li-ion, which affects the battery life. Compared to other material families, the ‘layered’ materials are the most attractive in the sense of the three attributes listed above, and layered lithium transition metal oxides containing nickel (Ni), cobalt (Co) and manganese (Mn) have recently emerged as a promising family of cathode materials. Aside from lithium ions, other elements play a role as building blocks forming a host structure for Li-ions (guests) to be inserted or extracted. Depending on the properties of the host structure, its electrochemical performance as a battery material is determined. For these multi-component layered systems, the current trend moves toward increasing the content of Ni in layered systems (known as Ni-rich layered materials) since Ni is capable of uptaking and delivering twice the charge, i.e., Li-ions of the other two. As Ni atoms occupy a large part of the transition metal layer in the host structure, it becomes a major factor in determining the overall properties of the host structure. Therefore, understanding the effect of increasing Ni content on the layered structure is important to designing high-energy electrode materials. This series of materials containing Ni and other elements appear to inevitably have so-called ‘cation disorder,’ a phenomenon in which some of the Li-ions and Ni atoms switch positions from their own layers. This happens due to the fact that some of the Ni atoms exist in the valence state 2+ lower than Co or Mn as synthesized. The presence of Ni atoms in the Li-ion layer adversely affects the Li-ion movement in the Li-ion layer. In contrast to such a general perception, the study finds that the degree of cation disorders is mitigated upon increasing the Ni content in the lattice up to a certain concentration, and also reports that the oxidation state of Ni in the pristine compounds contributes significantly to cation disorder. Moreover, it is demonstrated that the extent of cation disorder critically affects the phase transition behavior during charging or discharging, and as a result, the phase transition becomes smoother with increasing Ni content. This smooth phase transition reduces the strain on structural behavior during cycling; consequently, it enhances the cycle performance of the electrode material. In addition to the relationship between the Ni content and the phase transition, it was discovered that the actual environment in which Li-ions are situated is not directly linked to the total height, a sum of the Li-ion layer and the transition metal layer (c-axis). The height of the lithium layer becomes larger with increasing Ni content, even though the c-axis decreases. More importantly, it is shown that the lithium ion channel retains the environment where lithium ions can visit or leave, even if the c-axis shrinks from the initial dimension. The results for the Ni-rich layered materials that are counter-intuitive account for the superior electrochemical performance, and address the misconception of Ni element in Ni-rich layered systems. Furthermore, this article provides a new perspective on the role of Ni in layered systems and disputes the conventional view concerning the c-axis parameter that has been considered a key factor in interpreting the behavior of Li-ion movement and the corresponding electrochemical performance. Hence, these results may suggest some aspects to consider in the design of high-energy electrode materials for next-generation batteries. University College

- Creation of Two-Terminal Tunneling Random Access Memory (TRAM) Inspired by Brain Neurons
- Creation of Two-Terminal Tunneling Random Access Memory (TRAM) Inspired by Brain Neurons A new memory device inspired by the neuron connections of the human brain has been designed. The research, published in Advanced Materials as a back cover paper, highlights the device's highly reliable performance, long retention time, and endurance. Moreover, its flexibility makes it a promising tool for the next-generation soft electronics attached to clothes or the body. The brain is able to learn and memorize thanks to a huge number of connections between neurons. The information humans memorize is transmitted through synapses from one neuron to the next as an electro-chemical signal. Inspired by these connections, scientists constructed a memory called two-terminal tunneling random access memory (TRAM), where two electrodes referred to as 'drain' and 'source' resemble the two communicating neurons of the synapse. TRAM is made up of a stack of one-atom-thick or a few-atoms-thick 2D crystal layers: the semiconductor molybdenum disulfide (MoS2) with two electrodes (drain and source), a tunneling insulator of aluminum oxide (Al2O3), and a floating gate of graphene layer. The researchers secured a large-area memory integration technology using a large-area grown graphene and a two-dimensional semiconductor through chemical vapor deposition (CVD). In simple terms, memory creates program (logical-0) and erase (logical-1) states by charging and discharging the graphene floating gate through the h-BN tunneling barrier. By effective charge tunneling through the crystalline h-BN layer and storing charges in the graphene layer, TRAM demonstrates an ultimately low off-state current of 10^-14 A, leading to ultra high off/on ratio over 10^9 about ~10^3 times higher than other two-terminal memories. Furthermore, the absence of thick, rigid blocking oxides enables high flexibility, which is useful for soft electronics. Our memory device can be useful for next-generation neuromorphic systems and wearable, body-attachable electronics in the near future.
