In cars, plastic fender liner, as well as many other non-metallic parts, are attached to the body with self-tapping screws. After several screwing-in of fasteners (or from vibration during operation), the hole is developed and the connection is weakened. When tightened, the "self-tapping screw" rotates.

The paperclip holds the screw

In this case, first insert a hook made of soft steel wire (you can use a paper clip) into the hole, and then screw in the screw. After that, cut the wire with wire cutters, leaving and bending a small end on the outside: in this way we get a bracket from the hook that will not fly off even when the fastener is subsequently unscrewed.

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. ... >>

Material for creating an artificial brain 15.06.2021

Scientists have found an opportunity to create an artificial synapse to solve problems similar to the human thought process. Today, many options are offered for this, and one of the most promising is seen in ferroelectrics. FeRAM memory has been produced on such materials for 20 years, and a new study shows how to make memory elements of atomic thickness and get closer to neuromorphic calculations in the size of a processor.

In commercially available FeRAM memory, the switching element is usually made of a piezoceramic, namely lead zirconate titanate (PZT). The property of the material to maintain polarization even after the removal of an external control signal - an electromagnetic field - gives the FeRAM memory its most important property of energy independence. It retains data even when the power is off. To imitate the work of the brain - this is extremely important. But in its current form, the FeRAM cell is too large and the "brain" with its use will be very, very large.

For the manufacture of artificial synapses, thin-film structures a few atoms thick are convenient - this will give small dimensions, high density and low power consumption. It turned out that hafnium oxide (HfO2) is a rather promising ferroelectric material for thin-film artificial synapses. This material is perfectly deposited from a gas environment using modern methods for creating thin-film structures with high precision and under reliable control. The temperatures of the film making processes are compatible with the CMOS process technology and will not burn the chip elements during the chip fabrication process.

A certain problem was that the ferroelectric properties of HfO2 are relatively unstable, but the addition of zirconium (Zr) to it solved this problem. Thus, the hafnium-zirconium oxide (HZO) compound has proven to be one of the strong candidates for memory fabrication using ferroelectrics and promises to revolutionize the field of memory computing.
