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 ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Miniature rocket engine powered by water 20.09.2023

Researchers from Imperial College London presented the world with a tiny miracle of technology - the ICE-Cube Thruster (Iridium Catalysed Electrolysis CubeSat Thruster) rocket engine, which operates due to iridium-catalyzed electrolysis. This micromotor is so tiny that its production is carried out using the same methods as the production of semiconductor chips. The engine is designed to equip compact satellites - CubeSats.

As noted on the New Atlas portal, up to 90% of space launches focus on launching small satellites weighing up to 10 kilograms into low Earth orbit. Many of them are not even larger than a regular smartphone. For such spacecraft, creating components at the right scale is a challenge. One of the main challenges is creating small rocket engines, given the limited parameters of such satellites. In this case, the engines must not only be miniature, but also as simple as possible, do not require the creation of a vacuum, consume little energy and be safe to use without using toxic materials.

The ICE-Cube Thruster rocket engine, created with the support of the European Space Agency, is only about 2 centimeters long, and the length of the combustion chamber and nozzle is only 1 millimeter. It requires only 20 watts of electrical power to operate. During tests, the engine produced 1,25 millinewtons of thrust at a specific impulse of 185 seconds—about half a billion times less than the thrust of the engines used on the space shuttle.

However, the real uniqueness of this micromotor is that it uses ordinary water as fuel, which is absolutely non-explosive and non-flammable. The principle of operation is to carry out electrolysis of water using electric current, as a result of which water is split into hydrogen and oxygen. These elements are then fed into the combustion chamber, creating the necessary thrust to correct the satellite's orbit.

The use of water as rocket fuel not only promotes environmentally friendly space exploration, but also reduces the overall mass of the spacecraft, since it does not require the use of complex systems for its storage and supply. However, developing the combustion chamber and nozzles for such an engine, which are essentially two-dimensional, presented a real challenge, requiring microelectronics techniques and microelectromechanical systems (MEMS) technology, which is typically used to process silicon wafers to produce chips with micrometer precision.
