Random interesting fact from the Great Encyclopedia:

Why was the ship's bell called a rynda?

Initially, the word "rynda" appeared in Russian to designate a squire-bodyguard of the tsar on campaigns. In the meaning of the ship's bell, the rynda began to be used later. This happened as a result of the Russification of the English ship command "ring the bell" ("ring the bell"). Our sailors turned it into a "rynda bey", so the bell became a bell.

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 ... >>

Hydrogel for flexible electronics 18.03.2021

In the field of robotics, metals have advantages such as strength, durability, and electrical conductivity. But they are heavy and rigid, properties that are undesirable in soft and flexible laptop and human-machine interface systems.

On the other hand, hydrogels are lightweight, stretchable, and biocompatible, making them excellent materials for making contact lenses and tissue engineering scaffolds. However, they are poor conductors of electricity, which is essential for digital circuits and bioelectronics applications.

Researchers at the Soft Machines Lab at Carnegie Mellon University have developed a unique silver-hydrogel composite that is highly electrically conductive and able to conduct direct current while maintaining soft pliability and deformability.

The team placed micrometer-sized silver flakes in a polyacrylamide-alginate hydrogel matrix. After passing through the process of partial dehydration, the flakes formed percolation networks, which were electrically conductive and resistant to mechanical deformations. By controlling the process of dehydration and hydration, the flakes can be made to stick together or break apart, forming reversible electrical connections.

The composite can be printed by standard techniques such as screen lithography, similar to screen printing. The researchers used this technique to develop skin electrodes for neuromuscular electrical stimulation. The new material is able to cover a large area of the human body as a second layer of nervous tissue.

Future applications could include the treatment of muscle and movement disorders, such as helping someone with tremors from Parkinson's disease or difficulty grasping with their fingers after a stroke.
