How do wireless smartphone chargers work? / Amazing experiment (2021/10/08)
Some smartphones can be charged without a cable.
Induction heaters can also make LEDs flash remotely.
How is electrical energy transferred through the air?
This clever mechanism utilizes the difference between batteries and wall outlets.
Warning: Do not place an LED circuit on an induction heater. It is dangerous to do so without taking special precautions.

Hemispherical soap bubbles that resemble the Death Star! (2020/09/01)
Просмотров 718День назад
You can find a bit of science in something that absorbed you as a child. Have you ever seen a hemispherical soap bubble? If not, you can make some by exposing soap bubbles to the air for a while. Once you find one, consider how it was created. Here is the answer. FYI: For the sake of simplicity, we have disregarded a reflection phase change that occurs when light waves are reflected by a bubble...
Using a material to make a one-way light path! (2019/08/20)
Просмотров 351Месяц назад
A large, south-facing window can make you feel freer and more relaxed, but it can also make you anxious about being watched! In general, light can propagate through materials in all directions. However, a one-way light path can be created with some specific materials and components. In fact, we would have a lot of trouble without a device called an "optical isolator." In this video, we'll show ...
Music-free ver.: Optical antennas: sophisticated infrared light manipulation technology (2020/11/04)
Просмотров 20 тыс.4 месяца назад
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 i...
Cooling with magnet! Developing magnetic refrigeration to make liquid hydrogen (2020/02/06)
Просмотров 6 тыс.10 месяцев назад
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)
Просмотров 1,5 тыс.10 месяцев назад
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 ...
A novel liquid that converts vibration into electricity! (2021/07/01)
Просмотров 3,1 тыс.10 месяцев назад
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)
Просмотров 10011 месяцев назад
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...
AI-aided discovery! Thermal insulating film with world-record-breaking capabilities (2019/10/02)

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)
Просмотров 40211 месяцев назад
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...

A secret of fiber fuse veiled in its bright light emission
Просмотров 601Год назад
We at NIMS have been performing a demonstration of fiber fuse for our visitors since 2009. Just one look will leave you fascinated with the bright spot of light running along an optical fiber. However, only a few of you probably know the research conducted on this phenomenon by a researcher in NIMS. In this video, we briefly show how we focused on this running target and revealed the mechanism ...
