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 ... >>

A new method for converting carbon dioxide into methane 02.03.2020

Japanese scientists led by Waseda University professor Yasushi Sekine proposed to carry out a low-temperature catalytic reaction for the synthesis of hydrogen and carbon dioxide into methane using an electric field. The existing industrial process for converting carbon dioxide into methane through the catalytic reaction of hydrogen and carbon dioxide has a number of technological difficulties. In particular, the yield of methane is highly dependent on the required temperature, which should be between 300 and 400 degrees Celsius.

Scientists have proposed a new, low-temperature method (100 degrees Celsius), which produces more efficient production of methane from carbon dioxide than other similar methods.

The developed method uses the interaction of carbon dioxide with nanoparticles of cerium oxide on a ruthenium catalyst when an electric field is applied. Such a catalyst has shown high and stable catalytic activity for the conversion of carbon dioxide to methane by hydrogenation in an electric field.

Researchers claim that this method can be used to obtain methane from carbon dioxide emitted into the atmosphere by industry. The gas obtained in this way can not only replace fossil fuels, but also prevent global warming in the long term.

The method of producing methane using electricity consists of two stages. Through electrolysis, water decomposes into oxygen and hydrogen. The hydrogen is then mixed in the presence of a catalyst with carbon dioxide to produce methane.

The Power-to-gas technology, developed in Germany in 2008, is based on the chemical reaction of obtaining methane from carbon dioxide. The idea was to channel the excess electricity generated by power plants into gas production. Thus, it is possible not only to "storage electricity", then using gas as a fuel for power plants, but also to obtain gas for industry.
