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.

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. ... >>

Graphene crossed with nanotubes 29.11.2014

Scientists from Rice University (USA) grew a two-dimensional sheet of graphene on a sheet of copper, and then applied an iron catalyst to it and covered it with a layer of aluminum oxide. The resulting multilayer "sandwich" was treated at high temperature with acetylene and ethylene, as a result of which a whole "forest" of carbon nanotubes grew on the graphene surface.

In an innovative material, nanotubes are covalently bonded to graphene, in fact, the nanomaterial is a homogeneous sheet of carbon, due to which there is no resistance at the junctions. The height of the nanotubes is 120 micrometers, while the hybrid has an extremely high specific surface area: about 2 thousand square meters per gram of substance.

The hybrid nanomaterial may be an ideal candidate for creating electrodes in supercapacitors, which are electrochemical power sources intermediate between capacitors and batteries. Since layers of ions act as plates in them, such electrodes require both a high specific surface area and low resistance, which can be provided by an innovative material.
