70% of the Earth’s surface is taken up by water, and 97% of that water consists of seawater. The seawater’s abundance is drawing attention to it as ‘the’ energy resource for the next generation. Recently the research team of Professor Changshin Jo (GIFT, CE) and Hyebin Jeong (Ph.D. candidate in CE) identified the outstanding performance of chelating agent-applied seawater batteries (SWBs). The research was published recently in the international journal Chemical Engineering Journal.Lithium-ion batteries are widely used in mobile electronics and electric vehicles. But it has a danger of explosi

Would there be any optical element that can eliminate the camera lens of the part of the smartphone which protrudes? The answer is yes. In 2019, the World Economic Forum, (WEF) has chosen metalens as one of the Top 10 future technologies. Metalens is a very thin and light planar optical device consisting of an array of nanostructure and has recently attracted so much attention that it is composed of a special issue in the world-renowned journal Nature Photonics. However, due to the necessity of precise technology and high-cost burden, making metalens is not simple. Recently, a research team le

A number of technologies to combat climate change are actively under research. Among them are radical ideas to alter the behavior of the global climate system or to remove carbon dioxide straight from the atmosphere. To meet the goals set by The Paris Agreement, cutting down emissions alone is no longer sufficient, although it would have been a couple of decades earlier. The global emission rate is still on the rising curve, especially for countries that are just emerging out of poverty. To meet the 2-degree goal solely by cutting down emissions would require profound transformations in nearly

Voice phishing has been mainly targeted to the elderly who do not know much about finances. However, in recent years, the amount of voice phishing damage among young people in their 20s has continued to increase. The Financial Supervisory Service (FSS) recently released data titled “The Status and Key Characteristics of Voice Phishing Damage in 2022.” According to this, the amount of voice phishing damage continued to decrease. However, the amount of damage in the 20s age group increased from 6.6 billion KRW in 2020 to 9.2 billion KRW last year 2022, and the proportion of the affected age grou

Recently, a domestic and foreign research team collaborated and successfully devised a transplantable cell sheet for a wound. This cell sheet can be transplanted to a large and complex affected area like burns. Thus, the cell sheet is expected to present a new paradigm for wound regeneration treatment.A joint research team of Professor Sungjune Jung (MSE), Prof. Róisín M. Owens (University of Cambridge), and Prof. Jae Ho Kim (Pusan National University, School of Medicine) published a journal regarding the method to deliver a cell sheet to a target tissue, in the world-renowned scientific journ

Artificial intelligence (AI) has revolutionized numerous industries. For example, ChatGPT, an AI platform powered by deep learning, is widely recognized for its remarkable capacity to perform various tasks, such as writing, translating, and coding, by simply answering questions. However, this process requires extensive learning, resulting in increased power consumption and delayed calculation time, thus requiring efficient semiconductor technology.There is a need for a high-performance AI semiconductor device that is power-efficient, durable, and accurate. To meet this demand, a research team

Shortform. A phrase that is synthesized with “short” and “form”. Recently, a considerable number of people talk about how long they have spent on screen rolling with watching shortform and how addictive it is. Famous platforms such as Instagram, Youtube and TikTok all provide shortform content, where most people spend time vacantly. Thinking it as a problem, TikTok reported in early March that they had decided to decide to restrict users under the age of 18 to only watch for 60 minutes in order to raise awareness of how much time young users are spending on its app. In order to continue using,

Ever since the pandemic, over-the-top media services (OTT) have been an inseparable part of our life. This phenomenon led to not only a boom in the industry but also global recognition and exports of Korean content (K-Content). But this hype seems to have inspired some wrong people. Both Korean and global OTT have been pulling their hair out over an illegal streaming website. Estimated 10 million users each month and a total of over 1.8 billion views, the site has illegally distributed many contents on their site, including many popular K-Content. Considering that domestic OTT platforms’ month

Baseball is a special sport in the sense that there is a way to directly help the team while sacrificing oneself. As such, sacrifice is necessary when preventing the corrosion of metals. We can use sacrificial metal that is easily oxidized to prevent more important metals from corroding. Metals used in galvanizing processes, such as iron plates in street lamps or home appliances, are representative examples of important metals that need sacrificial metal. A technology that can solve the chronic problems in water electrolysis tanks for clean hydrogen has been proposed lately, drawing attention

Small-molecule drugs such as painkillers or digestive drugs are synthesized using chemical reactions. It is known that these small synthetic drugs need a drug-effective part called pharmacophore. However, introducing a pharmacophore into the drug molecule is limited because the overall synthetic procedures are complicated.Professor Lee Joongoo's research team (chb.postech.ac.kr) of the Department of Chemical Engineering (CE) conducted a joint study with Northwestern University and the University of Texas. The research team revealed a new fact that pharmacophores can be synthesized outside

Korea's mobile payment market is expected to undergo a major change.South Korea's Financial Supervisory Service announced on Feb. 3 that it is possible to introduce Apple Pay according to related procedures after reviewing whether Apple Pay services counter to local regulations and laws. As a result, experts expect that Apple Pay could be released in the first half of the year.According to business.com, mobile payment shares in the United States were in the order of Apple Pay, Google Pay, and Samsu

In the early morning of Feb. 6, a 7.8-magnitude earthquake rocked the calm brisk air of southeast Türkiye and northwest Syria. According to CNBC, the death toll surpassed 46,000 (still counting) with tens of thousands injured and displaced. The ongoing 12-year conflict in Syria and the outpouring of refugees as a consequence have made this disaster into a nightmare. After two weeks of searching for survivors buried under the collapsed buildings, rescue teams, and humanitarian workers are slowly shifting focus to rehabilitating the lost cities and providing food and shelter to the cities’ resid

Semiconductors have become indispensable in our daily lives. However, their continuous development has led to the problem of an increase in environmental costs. Lately, industrial and academic communities have struggled to cope with the inevitable production of greenhouse gases and waste. Currently, Metal oxide/polycrystalline silicon (LTPO) is the dominant semiconductor due to its long battery life, but its manufacturing process is costly and complicated. To meet the growing demands for environmental, social, and governance (ESG) management, continuous research to develop a more simple and en

A contact lens is a popular eyesight calibration instrument, used by 10% of Korean people. However, users often make a mistake, which is to sleep with lenses in. It causes infection by weakening the resistance of the corneal epithelium of the eye, and even the corneal pothole, i.e., corneal ulcer. In severe cases, it requires a corneal transplant.A joint research team of Professor Dong-Woo Cho (ME), Dr. Hyeonji Kim (ME), Prof. Jinah Jang (CiTE), Prof. Kim Joon Young · Mr. Jang Je-Hwan (Konkuk university, College of veterinary medicine) developed a new extracellular matrix-based sticky sealants

Developing an HIV vaccine has been the goal of many pharmaceutical companies since the disease spread around the world. However, the future of developing a reliable treatment has become murky again as yet another candidate for a possible HIV vaccine failed to prevent infections in late-stage clinical trials. The vaccine was developed by Jansson, the vaccine arm for Johnson & Johnson, and was thought to be the ‘last true candidate’ for the treatment of HIV. The trial for this vaccine was deemed the Mosaico study, which started in 2019 and involved multiple nations along with more than 3900 volu

Korea has been hard hit by a particulate matter (PM) problem this winter. PM is the term for “a mixture of solid particles and liquid droplets found in the air”. The density of PM reached “very high” more frequently this year compared to last year’s winter. The “Fine dust Emergency Reduction Act” was promulgated and executed by the Ministry of Environment on Jan. 7 and Jan. 8. According to the Environmental Protection Agency (EPA), PM-2.5, a particulate matter with a diameter of 2.5 micrometers and smaller, could cause respiratory diseases such as impaired lung function, asthma, and heart dise

Myocardial infarction (MI) is a disease in which the coronary artery supplying blood to the heart is narrowed or blocked, causing irreversible damage to the myocardium. Recently, the transplantation of stem cells to the damaged region was found to enhance the regeneration of damaged heart tissue. However, the low engraftment rate of stem cells on a dynamically beating heart has become a major obstacle.Professor Dong Sung Kim (Department of Mechanical Engineering) and Dr. Andrew Choi succeeded in transplanting in vivo priming bone marrow mesenchymal stem cell (BMSC) sheet based on thermorespons

Among many keywords that describe the year 2022, runaway climate change and a planet of 8 billion can be thought of as one of the most symbolic events. There have been and still are numerous reports suggesting the Earth is quickly approaching the tipping point, and, as the global population soared above 8 billion this November, the hours on the climate clock are ticking exponentially faster. Overpopulation is the elephant in the room of climate change but one that is often considered taboo. Secretary-General António Guterres, with regard to the population reaching 8 billion, said “[it is] an o

On Dec. 16, the Japanese government declared revisions to three national security documents, the National Security Strategy, the National Defense Strategy, and the Defense Buildup Program. They explained their rationale for the revisions citing China’s rise and conflict with Taiwan, alongside North Korea’s continued provocations through nuclear weapons and missiles.The new documents allow the Japanese to approve certain capabilities to counterattack enemy military infrastructure. This is seen as a major divergence from the pacifist route the Japanese had been seen to have taken since their def
