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.

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. ... >>
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 ... >>

Perovskite solar cells
17.07.2022
Perovskite is an extremely promising mineral for the construction of solar panels. However, the main problem of such products is their short service life. Researchers from Princeton University in the US have finally tested in the laboratory a sample that can work without replacement for up to 30 years in real conditions.
Although silicon has been the main material for solar panels for decades, perovskite has been actively gaining ground over the past 15 years. Perovskite is as efficient as silicon but allows for less expensive, lighter and more flexible panels. However, perovskites are not very stable and are rather short-lived in real-world use.
In the new study, the Princeton scientists added a special intermediate layer just a few atoms thick between the light-absorbing perovskite and charge-carrying layers to stabilize the structure. The intermediate layer is made of carbon disulphide, lead, iodine and chlorine and is used to protect the structure from rapid burnout.
Although similar solutions have been proposed before by various teams, the new formulation has the potential to keep solar cells alive for more than 30 years - the first solution in its class to cross the 20-year threshold.
For now, it's just about experimentation. The researchers used an artificial aging chamber to evaluate the "survivability" of the panels, in which the elements were exposed to sunlight and temperatures ranging from 35°C to 110°C. After extrapolating the data, the team concluded that under standard climatic conditions, the new solution can work for 30 years.
According to scientists, the artificial aging chamber used will allow testing the stability of not only perovskite, but also any other solar cells.
