Music-free ver.: Optical antennas: sophisticated infrared light manipulation technology (2020/11/04)
Thank you for your patience while waiting for our revised video about optical antennas. We hope this music-free version will be favorably received.
----
Have you heard of "metamaterials"? These sophisticated materials contain nano-scale patterns on their surfaces that allow us to control light.
At NIMS, we have developed a novel gas sensor that incorporates a metamaterial with a special pattern on its surface capable of emitting and absorbing infrared light at a desired wavelength.
How does it work? What can it be used for? Watch this video to find out!

Cooling with magnet! Developing magnetic refrigeration to make liquid hydrogen (2020/02/06)
Переглядів 4,3 тис.7 місяців тому
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, con...
Amazing! Water evaporates rapidly thanks to nanoparticles that convert sunlight to heat (2018/03/15)
Переглядів 1,4 тис.7 місяців тому
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 ...

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...

Notice certain frequencies have a very high absorption compared to the average. This is the quantum transitions in the atoms and molecules in the atmosphere. 2.4 GHz is especially prone to absorption via water molecules. This is why it is a free licence band.

    This video appears to be only a thinly-disguised advertisement for Toyota Hydrogen cars. And more than 95% of the Hydrogen which is available at those scarce refilling stations is supplied by oil companies..In short, a Hydrogen economy is a pipe dream. Hydrogen-powered vehicles, even when using fuel cells, are about as inefficient as fossil-fuelled vehicles, in terms of energy used compared to energy available in the fuel. They are around 25% efficient at best; about the same efficiency as a Diesel-fuelled car. In contrast, fully electric cars are achieving at least 70% efficiency. And electricity doesn't have to be mined, refined or transported in trucks to the point of sale.
