Cooling with magnet! Developing magnetic refrigeration to make liquid hydrogen (2020/02/06)
Although it may seem strange, magnets can be used to cool other materials. This technology is called "magnetic refrigeration."
You may be wondering how this is possible. In this video, we illustrate the principle using air conditioners and rubber balloons.
Researchers at NIMS are working on magnetic refrigeration to enable liquid hydrogen to be made, stored and transported more efficiently, contributing to the development of a hydrogen economy in the near future.
FYI: In this video, we cooled a piece of gadolinium metal, which exhibits ferromagnetism at room temperature in the same way that iron, cobalt and nickel do. Gadolinium loses its ferromagnetic properties when it is heated even slightly. This makes it useful in magnetic refrigeration.

Amazing! Water evaporates rapidly thanks to nanoparticles that convert sunlight to heat (2018/03/15)
zhlédnutí 1,3KPřed 5 měsíci
Only a few seconds after exposing a water surface to sunlight, vapor appears. Although the water remains at room temperature, it vigorously emits steam. This mysterious phenomenon is made possible with novel nano particles developed by NIMS. This is promising for the desalination of seawater because of its highly efficient conversion of sunlight to heat. Original Japanese version was published ...

Thank you for watching our video and leaving valuable comments, some of which pointed out that the background music didn't work well. We're currently working on a revised version. Please bear with us and return to our channel soon to see the improvements. Have you heard of "metamaterials"? These sophisticated materials have nano-scale patterns on their surfaces that allow us to control light. W...
A novel liquid that converts vibration into electricity! (2021/07/01)
zhlédnutí 2,7KPřed 5 měsíci
When you tap a piezoelectric material, it generates an electric current. However, these materials have until now always been solids. Here at NIMS, we created a flexible liquid version. This was made possible by attaching "branched side chains" to the piezoelectric molecules. Our skillful researchers continue to develop liquid versions of advanced solid materials. Japanese original version was p...
NIMS investigators: serious accident detectives! (2018/11/21)
zhlédnutí 77Před 5 měsíci
NIMS has found the causes of various accidents over the years, including a 1985 Japan Airlines plane crash. From a few faint clues found in the wreckage at the scene, we identified the immediate cause and technical pitfalls that led to the accident. In this video, we take a look at how our experts leverage their vast storehouses of metal materials experience and knowledge to solve these mysteri...

Artificial intelligence has boosted NIMS's development of new materials! Using AI, we were able to skip the conventional process of experimenting with thousands of elemental combinations and rapidly discovered a thin film with world-record-breaking insulation capabilities. How did we use AI? What kinds of thin films did we make? Watch this video and find out! Original Japanese version was publi...
Self-healing structural ceramics (2018/10/10)
zhlédnutí 253Před 5 měsíci
Although the general public may view ceramics as fragile, we at NIMS have developed self-healing ceramics to boost the performance of aircraft engines, which operate at high temperatures and must be lightweight and fuel efficient. The first self-healing ceramic was invented in 1995 in Japan. However, its healing process required heating at 1000 degrees centigrade for 1000 hours. We elucidated t...
