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 ... >>

Improved power generation from dissipated heat 01.06.2021

A team of scientists from the University of Colorado at Boulder has developed a new cell to generate power from dissipated heat that would simply escape into space. The new development turned out to be 100 times better than previous similar devices, but for commercial purposes, the efficiency of the element needs to be increased by another 100 or 1000 times.

So-called rectifying antennas or rectifying antennas can generate electricity from an external electromagnetic field (radio frequency radiation). Scientists have created a rectenna to generate electricity from heat. The operation of the element is based on the tunnel effect. The problem was set in such a way that to collect energy from heat, an element as small as possible was required, but it was necessary to solve the problem of resistance growth as the elements were reduced.

The tunnel effect that scientists have achieved on the element actually means zero resistance to electron transition and a sharp increase in the level of production. The researchers were able to obtain such an effect after creating a gap between two dielectric layers between the junction contacts - the so-called quantum well. The selection of the gap and the thickness of the dielectrics was such that the electron tunneled from one contact to another, as if passing through a wall.

The scientists tested an array of more than 250 butterfly-shaped rectennas made from nickel, nickel oxide, alumina, chromium and gold, each about 000 nm long and 11 nm wide. The array was found to exhibit 6-100 times greater conversion efficiency than previous optical rectennas.
