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 ... >>

Created a material that emits a narrow spectrum of light when heated 30.03.2020

Physicists at Rensselaer Polytechnic Institute have synthesized a three-dimensional tungsten photonic crystal - a material that can control the properties of a photon - with six shifted layers. Its crystal structure is similar to diamond, and the material itself also has an optical resonator, which further narrows the emission spectrum. The photonic crystal itself compresses the emitted spectrum of light to a range of about one micrometer. The resonator allows you to narrow this value to 0,07 micrometers.

While testing the new material, the scientists placed it on a silicon substrate side by side with a blackbody made from carbon nanotubes. In the experiment, the authors heated the materials up to 600 K and measured the spectrum of the radiation emitted by them. It turned out that the emission peak falls at a wavelength of 1,7 micrometers, corresponding to the infrared range. Moreover, the intensity of such radiation is eight times higher than that of a black body.

Although the current theory is not yet fully able to describe the observed phenomena, scientists suggest that they are associated with the displacement of the layers of the photonic crystal and allow light to escape from many spaces within its structure. Photons bounce off a large number of obstacles in the crystal structure of the material and change their characteristics.

The new material can be used in areas such as energy collection, tracking and identification of military targets based on infrared radiation, and the production of high-performance optical sources in the infrared range. It will also find application in IR spectroscopy and optics as a component of an infrared laser.
