Random interesting fact from the Great Encyclopedia:

Do all cats purr?

When something smells delicious or you just feel good, you sometimes hum rather: "Mmmm! .." When the cat wants to express its pleasure, it purrs. The purring sound is produced by the vibration of the vocal cords. The cat draws air into the lungs, and it passes through the vocal cords along the way.

Thus, if desired, the cat can allow the vocal cords to vibrate with air pressure. When a cat doesn't want to purr, she doesn't use her vocal cords - and no purring! Of course, when we talk about a cat, we usually mean a domestic cat. But there are still many members in the cat family. Did you know that the tiger, lion, leopard, jaguar, coguar, ocelot, and lynx also belong to the cat family? As for the reproduction of various sounds, a domestic cat, in addition to purring, can also meow, howl and yell.

Other types of cats make different sounds. Lion and tiger can roar. Jaguar and leopard make a sound similar to a loud cough or bark. But the most interesting thing is that due to the different structure of some of the bones of the throat, neither a lion, nor a tiger, nor a jaguar, nor a leopard can meow! But all cats, regardless of their size, have the same body proportions. If you enlarge the photo of a cat to a large format, you will see that it is very similar to a tiger.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Graphene from boron 29.08.2021

Theorists long ago predicted the existence of film forms of boron of atomic thickness - borophenes. But in practice, growing a single-layer borophene turned out to be orders of magnitude more difficult than obtaining graphene. Dreams of creating a multilayer borofen with the possibility of interlayer energy storage seemed like fantasy at all.

However, scientists were able to obtain the conditions for growing two-layer borophene, although this happened quite by accident. A group of scientists from the American Northwestern University reported growing samples of two-layer borophene. The secret lay in choosing the right substrate for the process.

The simplest methods can be used to produce graphene, including atomically thin peeling using a film with an adhesive layer. Borofen cannot be separated in this way. Its structure is stronger and an atomically thin layer can only be grown on a special substrate. Moreover, all attempts to grow a two-layer borophene ended in failure - instead of the second layer, volumetric accumulations of boron were formed in the form of a single-crystal structure.

In one of their experiments with substrates for growing borophene, scientists at Northwestern University used silver that was heated to a certain temperature. The resulting substrate looked like a cascade of terraces with a relatively large area each. During the experiment, it turned out that on such a substrate, borophene was formed in the form of two neat layers. Nobody expected this, but everyone was pleasantly surprised - they found what they had long dreamed of.

Double-layer borophene is in theory a better fit for future batteries than graphene. It is more durable, flexible and lightweight. The distance between two layers of borophene is good for ion trapping and energy storage. This material promises to simplify the structure of the batteries and reduce their weight. Scientists hope that they will be able to study the opportunities that have opened up for obtaining borophene in volumes that will make it possible to reveal its properties and, as a result, bring the possibility of practical application closer.
