What does chemical and biological engineering study, and how is it changing our lives?

In this blog post, we’ll explore what chemical and biological engineering—a field that bridges various disciplines such as process engineering, applied chemistry, biotechnology, materials science, energy, and the environment, all based on chemistry and biology—studies and how it is applied in our daily lives.   My major is Chemical and Biological Engineering. Most people who encounter the...

How do shape-memory alloys “remember” their original shape?

In this blog post, we’ll explore the principles behind shape-memory alloys—which return to their original shape in response to temperature changes—as well as the characteristics of Nitinol, a representative material, and its various applications and limitations.   Generally, metals have an elastic limit—that is, a limit beyond which they cannot return to their original shape through elastic...

Control engineering—the brain of modern industry—how does it drive industry and technology?

In this blog post, we’ll explore the principles, history, and future role of control engineering, which powers various sectors of modern industry, ranging from smartphones to robots, semiconductors, artificial organs, and smart grids.   A man wearing a black turtleneck and jeans steps onto the stage. He soon pulls out a simple, futuristic-looking device and holds it up for the audience to...

Can fusion power really become humanity’s next-generation energy source?

In this blog post, we’ll explore whether fusion power can establish itself as a future energy source by examining everything from the principles of nuclear fusion—the process by which the Sun generates energy—to the characteristics of magnetic confinement and inertial confinement methods, as well as recent achievements in fusion research and the challenges that remain.   What is the Sun’s...

How is subsea drilling conducted, and how does it enable oil production?

In this blog post, we’ll take a detailed look at the subsea drilling process—from drilling wells to extract oil and natural gas buried beneath the seabed to protecting those wells using techniques such as wellbore lining, casing, and cementing, and finally connecting them to production facilities.   In modern society, oil remains a vital energy resource and industrial raw material. From fuel...

How Can Offshore Plants Be Optimized Through Simulation?

In this blog post, we’ll explore everything from the basic oil and gas production processes at offshore plants to why simulation is crucial in offshore plant design, and how to optimize using Aspen HYSYS.   Offshore resources such as oil and natural gas lie buried deep beneath the seabed. Various offshore facilities are used to explore, drill, produce, and process these resources. Offshore...

How have aircraft propulsion systems evolved?

In this blog post, we’ll explore the evolution of aircraft propulsion systems—from humanity’s longing for flight to piston engines, propellers, turbojets, turboprops, turbofans, and ramjets—and examine how this progression led to space propulsion technology.   The fact that people have constantly strived to reach the sky can even be found in Greek mythology. The story of Icarus, who flew...

How Is Synthetic Biology Opening Up New Frontiers in Electrical Engineering?

In this blog post, we’ll explore the emergence and development of synthetic biology—which aims to engineer and create living organisms based on a physical and chemical understanding of the nature of life—and examine how concepts of circuit and system design from electrical engineering are converging with the life sciences.   Suppose we are conducting a fruit fly cloning experiment in a...

How does ice cream that changes color when you lick it actually change color?

In this blog post, we’ll explore how humans perceive color and how the molecular structure and color of pigments change in response to pH changes, using the example of this fascinating ice cream that changes color as you lick it or as it melts.   On a peaceful Sunday afternoon, while enjoying a stroll in a quiet park under the warm sunshine, you stopped by a nearby ice cream shop and bought...

Why Did the High-Tech Swimsuits That Once Set a Flurry of World Records Disappear?

In this blog post, we’ll examine the hydrodynamic principles behind the high-tech swimsuits that shook the world of swimming, how they helped athletes improve their times, and why FINA decided to regulate them.   At the World Aquatics Championships held in Rome, a staggering 43 world records were set. The swimming world witnessed a wave of record-breaking performances, including a new world...
