What is stronger - web or steel?

The thread from which spiders weave the basis of their trapping web is thinner than a human hair, and its specific (that is, calculated per unit mass) tensile strength is higher than that of steel.

If we compare the gossamer thread with steel wire of the same diameter, then they will withstand approximately the same weight. But spider silk is 6 times lighter, which means it is 6 times stronger.

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 ... >>

Dual-Image TVs 13.07.2019

Hisense has announced the U9e series TVs, the world's first Dual-Image panels.

The device display is essentially a combination of a traditional color LCD display and an optional monochrome display. This solution was called BD Cell, and specialists from the Chinese company BOE took part in its development.

The applied technology provides a number of advantages in comparison with conventional LCD panels. So, the contrast increases by about an order of magnitude. In the case of Hisense U9e, this value exceeds 150:000.

In terms of image quality, the new TVs are comparable to organic light-emitting diode (OLED) panels, but at the same time they are much cheaper. We are talking about excellent color reproduction.

To date, there are three models in the Hisense U9e series - 55 inches, 65 inches and 75 inches diagonally. The resolution is not specified, but it can be assumed that the new items correspond to the 4K format.

Only the 65-inch version will go on sale this year and will cost around $2600. The other two models will become available next year.
