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 ... >>
Random news from the Archive X-ray laser on the table
02.07.2012
American physicists have created the world's first desktop x-ray laser. This development opens up huge opportunities for progress in many areas, including medicine, biology and nanotechnology.
For half a century, scientists have been trying to create a compact and inexpensive X-ray laser capable, in particular, of taking ultra-high resolution images. Such a device would allow one to look inside a living cell or study chemical reactions at the nanoscale.
Unfortunately, most modern synchrotrons that produce the X-rays required by scientists consume huge amounts of electricity. In addition, they are huge in size, often comparable to a football stadium. Naturally, this hinders their widespread use.
To get away from the need for a powerful energy source, an international team of researchers led by the University of Colorado Boulder has created a desktop device that uses more than 5000 low-energy photons in the mid-infrared spectrum. These photons can generate a high-energy X-ray photon, making it possible to capture the fastest processes, including the movement of electrons.
Under the influence of infrared laser pulses, noble gas atoms lose electrons, which are accelerated in infrared light, and return to the atoms. Kinetic energy as a result of this process is converted into x-rays. Thus, part of the infrared laser radiation becomes X-ray.
The desktop device produces a bright, directional X-ray beam with a wavelength 1000 times smaller than visible light. This allows the beam to penetrate various materials and study them at the nanoscale, inaccessible to other devices of this size and cost. The new technology will certainly come in handy in numerous studies on the development and optimization of a new generation of electronics, information and energy storage devices, and medical diagnostic technologies.
