A team of researchers from multiple organizations, led by Prof. Kim Ju-min (Departments of Chemical Engineering and Energy Systems Research) and his team, has developed a microscale flow mixing technique capable of synthesizing more even nanoparticles. The researchers expect their latest discovery to have a wide range of applications, including medical diagnostics, as well as preprocessing of specimens and reaction-based processes in microfluidics. Prof. Kim’s team worked with two other teams, led by Prof. Lee Chang-soo of Chungnam National University and Dr. Lee Sung-sik of ETH Zürich, respectively, to produce a microscale reactor. Their findings were published in a paper entitled, “Gear-shaped micromixer for synthesis of silica particles utilizing inertio-elastic flow instability,” featured on the cover of the February 7 issue of Lab on a Chip. Profs. Kim and Lee and Dr. Lee participated as corresponding co-authors. Hong Sun-ok, a recent graduate of Ajou University with a doctorate in energy systems research and now affiliated with Lotte Chemical, was listed as first author. Microfluidics is increasingly used in a number of applied fields, most notably for engineering point-of-care diagnostic devices that provide fast diagnosis. Efficient mixing of fluids is a crucial prerequisite for the preprocessing and core reactions of specimens in microfluidics. It is also the key performance requirement of micromixers. Given the near impossibility of generating turbulence in micromixers, the inefficient expansion-based mixing method has been preferred thus far. Manual mixing, which relies on conventional fluid dynamics, requires fluid channels with complex designs and complex manufacturing processes. Moreover, as layer-based mixing requires normal-state flows of fluid, the mixed output is prone to sedimentation along the fluid surface. Prof. Kim and the researchers discovered that flow instability, associated with diluted polymeric solutions, increases greatly in serpentine microscale channels that repeatedly contract and expand. They decided to apply this discovery to the development of a new micromixer with significantly greater efficiency. The inertio-elastic micromixer that came out of this discovery offers greater mixing efficiency at a wider range of flow rates. In other words, it is capable of more efficiently mixing a wider variety of fluid materials with greater simplicity. The researchers expect that their new model can be more easily applied to large-capacity micromixers. The researchers indeed applied their new micromixer to the synthesization of silica nanoparticles and confirmed that it was capable of producing particles of a more uniform size distribution (as measured in terms of distribution of particles of different sizes in a given specimen). They also demonstrated that their mixer was able to produce nanoparticles over a long span of time without the fluid channel becoming blocked—a problem common with conventional mixers. Prof. Kim explained: “Our study demonstrates that it is possible to design a micromixer capable of maximizing flow instability of viscoelastic fluids like polymer solutions. Our study is also significant because it demonstrates our technique by applying it to the synthesis of actual nanoparticles with a uniform size distribution.” This research has been made possible in part with support from the National Research Foundation of Korea’s Advanced Center of Excellence and personal research grants.# Captions* Upper left: The serpentine channel developed by Prof. Kim’s team, and a conceptual diagram of how it increases inertio-elastic flow instability to facilitate mixing.* Lower left: Particles mixed in a Newtonian fluid (a) show size distribution with a wide variance and nonspherical shapes (b).

A team of researchers from Ajou and Seoul National universities has discovered a new way to control the pace of cellular aging. The key anti-aging solution found consists in the reconfiguration of telomeres, often understood as “timers” of cell division, which promises to unlock the secret of aging. The findings of the latest research were published under the title, “Telomeres reforged with non-telomeric sequences in mouse embryonic stem cells” in the February 17 issue of Nature Communications, a prestigious publication on natural sciences, with Prof. Park Dae-chan (Departments of Biological Sciences and Molecular Science and Technology) from Ajou University and Prof. Lee Jun-ho from Seoul National University listed as corresponding authors. Kim Da-eun, currently studying molecular science and technology at Ajou’s graduate school, was also listed as a co-author. The cells that make up the human body continue to divide and multiply to sustain the natural functions of life and growth. At some point in time, however, cells stop dividing, while some genetic information is lost as cells repeat division. Telomeres are protective sheaths found at the tips of chromosomes that serve as a kind of shield against the loss of genetic information during cell division, as telomeres are lost instead of vital genetic information. As telomeres shorten to a certain length or below, cells stop dividing and begin aging. Cells that continue to divide more actively than others, such as reproductive cells, stem cells, and cancer cells, utilize an enzyme known as telomerase to maintain the telomeric lengths and continue to divide almost infinitely. In other words, the continued healthy functioning of cells relies crucially on regulating the lengths of telomeres and the number of times cells divide. An accurate understanding of how telomeres can best be preserved may be essential to effective cancer treatment and anti-aging strategies with minimal or no risk of side effects. Researchers have discovered a mechanism known as alternative lengthening of telomeres (ALT) in certain cancer cells, which maintains telomeric length without utilizing telomerase enzymes. In human cancer cells, however, researchers have so far found telomeres that utilize the ALT mechanism but whose sequences simply follow the general and repetitive pattern.The researchers on Prof. Park’s team have discovered, for the first time in the world, a recombination of telomeres with unique sequences in a mammalian model. A small number of embryonic stem cells from a mouse with its telomerase inactivated went on to activate the ALT mechanism to recover the normal pace of cell division. The cells divided by this ALT mechanism displayed amplified unique sequences. Prof. Park’s team named the new pattern they discovered the mouse template for ALT (mTALT), arguing that it provided clues as to the possible existence of alternative telomeres in human cancer cells as well.The researchers, moreover, employed a multi-omics analysis to trace how the ALT mechanism actually works, subjecting the mouse embryonic stem cells at diverse stages of growth—cells with normal telomeric lengths, cells in the aging stage, cells after ALT activation, etc.—to analyses of genomes, transcriptomes, single-cell transcriptomes, and proteomes. They were thus able to identify and demonstrate the molecular characteristics of ALT cells.The researchers commented: “Our recent study reveals the possible existence of alternative telomeres in human cancer cells. We have demonstrated that the concept of telomeres extends beyond the repeated sequencing structures found at the tips of chromosomes and telomerase, but may also encompass diverse mechanisms that protect the tips of chromosomes.”The research was made possible with support from the Ministry of Science and ICT and the National Research Foundation of Korea’s support programs for new and experienced researchers.Mechanism of telomeric change and ALT activation due to cell division

A team of Ajou University researchers has uncovered a new optical phenomenon in graphene, widely regarded as a material that holds the key to the future. The team’s findings are expected to pave the way for developing new applications, including superspeed optical signal processing using two-dimensional materials, quantum communications, and quantum sensing.Prof. Yeom Dong-il (Departments of Physics and Energy Systems Research, pictured left) and his team have discovered that interlaying two stacks of single-layer graphene can produce considerably more nonlinear optic signals. Their findings were published under the title, “Enhanced third-harmonic generation by manipulating the twist angle of bilayer graphene,” in the January 21 online issue of Light: Science & Applications (IF = 13.714, IF (%) = 2.577).The paper lists two of Ajou’s doctoral students, Ha Seong-ju (pictured middle) and Park Nam-hun (pictured right), as first authors. The credit also goes to Profs. Lee Jae-hyun (Department of Materials Science and Engineering), Yoo Young-dong (Department of Chemistry), Park Ji-yong (Department of Physics), and Ahn Kwang-jun (Department of Energy Systems Research), as well as Prof. Jung Je-il (Department of Physics) from the University of Seoul.Graphene, a two-dimensional material well known for its composition of pure carbon atoms, has been garnering much attention around the world for its high conductivity and transparency as well as flexibility—all the properties desired in next-generation materials for electronic and optical diodes. Stacking layers of single-layer graphene at an angle produces Moiré superlattices. Graphene has recently captured researchers’ attention as the angle at which these layers are stacked can produce dramatically different results, including both a superconductor with zero resistance and a perfect insulator. The Moiré pattern refers to superlattices that emerge with much greater frequency than with the original and denser patterns of nets or fabrics layered together at an angle.Prof. Yeom’s team seized upon the nonlinear optic phenomenon that occurred when strong light was projected onto their twisted bilayer graphene (tBLG). The Moiré superlattices of the tBLG, in particular, gave rise to van Hove singularities (i.e., points at which the state density function of electrons peak-like discontinuities) with the state density of electrons. Moreover, the team discovered that, when the energy gap between the van Hove singularities tripled the energy of light being projected, significant enhancement occurred in the third-harmonic generation (THG) efficiency. Based on this finding, the team was able to increase the nonlinear optic signals of the electrically controlled tBLG by as much as 60 times those of single-layer graphene.Prof. Yeom commented: “With this study, we became the first in the world to demonstrate that the angle at which graphene is stacked can be a new significant variable when it comes to controlling and enhancing the nonlinear optic properties of two-dimensional materials. I expect that our findings will contribute to the development of new superspeed optical signal processing techniques or quantum lighting sources that utilize the nonlinear optic properties of two-dimensional materials.”The study was conducted with support from the National Research Foundation of Korea’s Experienced Researcher Support Program and Korea Energy Technology Evaluation and Planning’s Energy Workforce Development Program.

The third Case-Based Learning Analysis Conference (CBLAC) was held on January 28, fostering debates on ways of applying artificial intelligence (AI) and big data to improve personalized learning conditions in higher education and increase the performance of adaptive learning.The conference, held by the Center for Teaching and Learning (CTL) at Ajou University, focused on the theme of “Introducing and Practicing Adaptive Learning in Higher Education.” The entire conference was livestreamed online via Zoom and YouTube, with 140 or so participants, drawn from both inside the school and outside, in attendance.Professor Jeong Jae-young of Ewha Womans University opened the conference with a keynote address entitled “The Age of AI: Direction for Innovations in Higher Education.” Professor Jeong introduced examples of innovation attempted by universities abroad and identified the lack of content and responsiveness in Korean universities’ AI education programs. He then stressed the necessity of changing pedagogic methods using AI.The keynote address was followed by a panel debate on preparations for introducing adaptive learning. Prof. Shin Jong-ho of Ajou University, who leads the CTL, was the first to speak, on the theme “Introduction and Practice of Data- and AI-Based Adaptive Learning at Ajou University.”Noting that the changing learning environment has increased the diversity of students, Prof. Shin emphasized the need to introduce personalized classes and learner-centered education methods that better cater to different students’ interests, aptitudes, and talents.Prof. Shin then proceeded to introduce Ajou’s model of adaptive learning, which supports personalized learning environments using AI. Adaptive learning refers to a method of education that utilizes intelligent information technology, such as big data analysis and AI, to assess individual students’ levels of knowledge and competency with accuracy and dynamically adjusts the types, content, and levels of education accordingly. Adaptive learning is chiefly designed to provide personalized learning environments tailored to different students’ needs.Since launching the development of the Ajou Teaching and Learning Analytics System (ATLAS) in 2014, Ajou University has been promoting adaptive learning on campus, culminating into the creation of the Pathway to Ajou Student Success (PASS), a data- and AI-based personalized learning system that was introduced in 2019.Prof. Shin relayed that dividing students into different groups and applying prescriptive learning programs accordingly, with the help of Ajou’s model of adaptive learning, has improved students’ satisfaction with classes. Nevertheless, he also pointed out a number of obstacles preventing the progress of adaptive learning, including the lack of programs and curricula developed in Korea, language barriers, and resistance to the introduction of new systems. “As we are still in the early stages of adaptive learning,” he added, “it is necessary to develop more effective measures by pooling the experiences and lessons that Korean universities have gained.” The second debate unfolded on the theme of “Adaptive Learning-Applied Syllabi.” Prof. Hwang Eun-kyung of Ajou University first spoke about “Ai-Based, High-Intensity, Interactive Teaching Method: ALEKS Chemistry.” ALEKS is a program designed to enable individual students to learn at different paces and levels of difficulty. Prof. Hwang provided classes using Ajou’s own adaptive learning system and ALEKS, and compared the results.The professor noted that, although ALEKS automatically assessed students’ different levels of competency, the different workloads it imposed on students at different levels and the English lessons burdened some students. On the other hand, Prof. Hwang noted that Ajou’s own system enabled her to group students for group exercises based on assessment of their competency, and that such exercises significantly improved students’ satisfaction.Concluding, from her experience, that the truly important question of adaptive learning involves deciding how to apply the information on students it provides to classroom content and learning, Prof. Hwang argued that we need to “prepare different ways of teaching other than classroom learning based on a good understanding of how the adaptive learning system works.”Prof. Kan Jin-sook of Hallym University and Prof. Kim Heon-joo of Handong Global University also gave presentations under the themes “The AI-AL Innovation Strategy for Hybrid Learning at Hallym” and “A Case of AI-Based Personalized Education: ALEKS Statistics,” respectively.In his official greeting, Ajou President Park Hyung-ju remarked: “Ajou’s attempts to apply data-based analyses and strategies to the evolving learning environments predate COVID-19.” He also added: “I hope, through this conference, we can share our experiences with and lessons on adaptive learning in higher education toward finding a better way forward for all Korean universities.”The Ajou CTL provides consultation on class designs, develops new models of teaching and learning based on the latest methods, and provides learning advisory programs. The center’s scope of work has expanded recently to include content development, learning management systems, and other matters related to remote learning, allowing it to build a data-based teaching and learning support system capable of providing proactive and personalized support programs for different learning needs.Prof. Shin Jong-ho hosting the conferenceConference poster
