In this blog post, we’ll explore the principles of electrowetting, as well as the structure, advantages, and disadvantages of e-paper that utilizes this technology.   The Concept of E-paper and the Background of Interest Wouldn’t it be convenient if we could easily change the images or text on paper, just like in the movie *Harry Potter*? In reality, active development is underway for...

In this blog post, I will briefly explain the principles and applications of nanoparticle patterning using the electrospray method.   We live in an era of rapid scientific and technological advancement, and you have likely come across the term “nano” at least once in newspapers or online. I would like to briefly introduce one method in the field of nanotechnology, where active research is...

In this blog post, we’ll take a closer look at what DSSCs are and how they address the limitations of conventional solar cells.   Oil has long been a critical energy source for South Korea’s industrial development. However, due to limited reserves, price volatility, and environmental concerns, interest in renewable energy sources has grown. Renewable energy comes in various forms, such as...

In this blog post, we’ll take a concise look at the principles, diagnostic process, and expected benefits of “the evolution of diagnostic technology using DNA chips.”   As human medical technology has advanced dramatically, we are getting closer to overcoming intractable diseases such as cancer and expanding treatment options for conditions that were once considered incurable. However...

In this blog post, we’ll explain the structure and operating principles of DSSCs (dye-sensitized solar cells) in an easy-to-understand way.   Energy plays a vital role in the many benefits our civilization enjoys. As the limitations of conventional energy sources and environmental destruction become increasingly apparent due to the risk of fossil fuel depletion, climate anomalies, and global...

In this blog post, we will summarize the principles of DNA fingerprinting, how its main methods—RFLP and PCR—work, their advantages and disadvantages, and real-world applications.   September 11, 2001, was a nightmarish day for Americans. Members of Al-Qaeda, a fundamentalist Muslim group led by Osama bin Laden, hijacked four airplanes that morning and crashed two of them into the Twin...

In this blog post, we will explore the basic concepts, key tools, processes, and applications of recombinant DNA technology.   Biotechnology and Recombinant DNA Technology It is no exaggeration to say that the 21st century is the era of biotechnology. The term “biotechnology” was first used in 1917 by a Hungarian engineer, who described it as “all work that produces useful substances from...

In this blog post, we’ll examine the principles behind DDoS attacks and explore common defense methods, along with real-world examples.   In the summer of 2011, the “PSN incident” became a major issue following a cyberwar between Sony and hackers worldwide. This incident began when “Geohot,” an American hacker famous for hacking the iPhone, hacked Sony’s PS3, prompting Sony to take legal...

In this blog post, we will provide an easy-to-understand overview of the basic principles and components of CVD, its major variations, and its industrial applications.   Background When I first heard the news of Shuji Nakamura winning the Nobel Prize in 2014, I wondered whether the development of the blue LED was truly an achievement worthy of the Nobel Prize. After reviewing Shuji’s papers...

In this blog post, we’ll use the “Meister High School” analogy to explain the concept and advantages of modular processors in simple terms.   What is a Meister High School? “Meister” means “master craftsman” in German and refers to a system that trains students at the high school level in specialized industrial skills and knowledge so they can be immediately deployed in the workforce upon...
