Spider silk is a natural super material. These seemingly soft filaments, which are stronger than steel and harder than Kevlar, have very good elasticity. Because of these characteristics of spider silk, scientists have been exploring its role in medicine and military.
However, the application of spider silk in computers is a new area of ​​discovery. According to the Wired UK website, some scientists have discovered that spider silk, like fiber optic cables, can be used to transmit information.
Scientists have found through testing that light travels in spider silk as easily as in fiber optic cables. "When we started testing spider silk, we didn't know what we could find," says Nolween Huby, a physicist at the Department of Physics at Rennes University in France. "We thought, 'Why don't we use it as a fiber experiment to spread light?' ?"
On an integrated circuit chip, Huby and his team experimented with the transmission of laser light on spider silk and found that the function of spider silk and glass fiber optic cable is the same. This means it can transmit information on electronic devices. However, the transmission of spider silks will lose more information, but Huby said that through the coating and further development, spider silk can get better transmission capabilities.
This discovery of scientists has important medical significance. For example, spiders are used to carry light sources to create images inside the patient's body. Because the spider silk is very fine, when the doctor is making a diagnosis, he only has to open a small hole in the patient.
However, spider silk is difficult to produce on a large scale. Scientists consider using silk because it possesses many characteristics of spider silk. Fiorenzo Omenetto, professor of biomedical sciences at Tufts University, Mass., believes that biofilaments are harmless and the body will not have adverse reactions to them. He believes that in the future, doctors will implant biofilaments with electronic functions into patients. The patient does not need to worry about the condition of this monitoring device because the body can absorb this material.
The greatest benefit of using biofilaments to make electronic devices is that they can be degraded, which effectively reduces e-waste. Omenetto's team has experimented. They mixed the extracted silk proteins with other substances to create electronic filaments, and developed a device that can emit blue laser beams. The components of this device are completely degradable and consume less energy than ordinary laser guns.
Perhaps through the development of technology, the problem of e-waste will eventually be solved. However, this future is still far away from us. Omenetto said that the degradable circuit is only one aspect, and engineers still need to consider how to make degradable batteries, screens, and other components in modern electronics.
Rotary Rings are a type of rotating seal widely used in various rotating equipment, such as rotary joints, rotary couplings, rotary connectors, etc. Its main function is to prevent liquid or gas leakage and maintain the normal operation of the equipment. In different applications, the material, structure, sealing method, size, etc. of Rotary Rings vary to adapt to different working conditions.
The materials of Rotary Rings are mainly divided into two categories: metallic and non-metallic.
Metal materials mainly include stainless steel, steel, copper, aluminum, etc., which have characteristics of high strength, corrosion resistance, wear resistance, and are suitable for rotary seals in harsh environments such as high temperature, high pressure, and high-speed.
Non metallic materials mainly include ceramics, silicon carbide, graphite, etc., which have characteristics such as high hardness, high wear resistance, and low friction coefficient. They are suitable for rotary seals under conditions such as low temperature, low pressure, and high speed.
The structure of Rotary Rings is mainly divided into three types: unidirectional rotation, bidirectional rotation, and rotational stationary.
1. Unidirectional rotating structure
The Rotary Rings with a unidirectional rotation structure can only rotate in one direction and are suitable for devices with only unidirectional rotation.
The Rotary Rings with a bidirectional rotation structure can rotate in two directions, suitable for devices that require bidirectional rotation.
The Rotary Rings with a rotating stationary structure are composed of a rotating ring and a stationary ring. The rotating ring contacts the stationary ring during rotation to achieve sealing, suitable for equipment that requires a rotating stationary seal.
The sealing methods of Rotary Rings are mainly divided into mechanical sealing and liquid sealing.
Mechanical sealing is achieved through the contact surface between the rotating ring and the stationary ring, which has the characteristics of high reliability, long service life, and simple maintenance. It is suitable for rotary sealing in harsh environments such as high speed, high temperature, and high pressure.
Liquid sealing is achieved by injecting liquid between the rotating ring and the stationary ring, which has the characteristics of good sealing performance, low friction coefficient, and preventing dry friction. It is suitable for rotary sealing under low speed, low temperature, low pressure, and other conditions.
The size of Rotary Rings is mainly determined by the equipment requirements, including inner diameter, outer diameter, thickness, shaft diameter, etc.
