Comments on the article
Most thyristors can be tested with a light bulb and a constant voltage that can light it up. "Plus" is fed to the anode, and the light bulb ("minus") is connected to the thyristor cathode (see figure).
Briefly connecting the anode and the control output, we "open" the thyristor. Even after disconnection, the light should glow.

Traffic noise delays the growth of chicks
06.05.2024
The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

A New Way to Control and Manipulate Optical Signals
05.05.2024
The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>
| Random news from the Archive Super glue that can withstand record temperatures
24.07.2022
Chemists at Tsinghua University in Beijing have developed a promising mixture for combining different items at extreme temperatures. The new adhesive withstands from -196 to 200 degrees Celsius and can be reused.
The new adhesive will be useful in heavy industry and aerospace applications such as rockets that face temperature fluctuations. The new substance belongs to the class of supramolecular adhesives.
The parts of the mix are specially designed to self-assemble into strong bonds during the curing process. The authors reported that one of the components is a ring-shaped molecule known as a crown ether, while the other is a small protein produced by bacteria.
When the described components come into contact and the mixture is heated, the crown ether rotates the protein and securely fastens any surface. In a series of tests, the scientists glued two steel plates together and found that they could withstand up to 22 megapascals. At the same time, the glue worked not only at room temperature, but also in any range of -196 to 200 °C. It also showed high strength characteristics when working with other materials and did not disintegrate even under water.
The team attributed the success to strong supramolecular interactions—a strong bond displaces water from a protein. This means that when the temperature drops, ice crystals cannot form and break the material, as often happens with other adhesives. An added bonus of the new technology is its reusability. The blocking adhesive components can be dismantled and recycled, after which the updated mixture can hold new materials together with the same strength.
The new supramolecular adhesive will be especially useful in scenarios where rigid objects face extreme temperature fluctuations. With it, it will be easier to service industrial enterprises using metals, as well as repair spacecraft and rockets in earth or lunar orbit.
