Ice can produce a charge during deformation, scientists have been found by experimental.
In the case of science, ice is flexoelectric properties. The authors have reported this discovery, both actual and basic consequences on the pages of natural physics.
Frozen water is one of the most popular substances on Earth. It is found in the glacier, on the peaks and in the extreme ice. However, studying the properties of ice continues to bring excellent results and the flexoelectric effect has become one of them.
We see that the tape generates charge to respond to mechanical voltage at any temperature. In addition, we have identified a thin Segneelectric layer on the surface at a temperature below −113 ° C (160 k). Segotoelectitity is an interesting discovery in itself, because that means that the tape may not have one, but two ways to create electricity: Segotheellectricity at very low temperatures and flexibility at higher temperatures to 0 ° C
This hotel put stones in a row with electric ceramic materials, such as Titan Dioxide, which is currently used to produce sensors and condenser.
ICE, Flexoelectricity và Shunderstorms
Perhaps the most useful consequence of this discovery can be called its connection to nature. The results of the study showed that the flexibility of the ice could play a role in the electrochemical of clouds in thunderstorms – and finally the origin of lightning.
It is known that lightning arises when the power potential is accumulated in clouds due to clashes between charged particles. Having reached a kind of threshold, this potential was released in the form of a lightning attack. However, the mechanism that the ice is charged, is still unclear, because the tape is not a voltage – it cannot produce a simple charge from compression during the collision.
Flexoelectric properties means that the production of electric ice is the result of its heterogeneous deformation.
In our research process, the potential of electricity arises from the bend of the measured bandage. In particular, the bar is placed between two metal plates and is connected to a measuring device. The results coincided with the previous ice particles observed in ICE clashes in ThunderClouds.
Prospect for the future
The group began to find new research areas to study practical applications of the properties of this tape. Although it is too early to discuss potential solutions, this finding can create a road to create new electronic devices using ICE as active materials, which can be done directly on cold vehicles.
