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 ... >>

Power consumption of OLED displays will decrease
24.11.2013
Specialists working at the universities of Bonn and Regensburg have managed to develop a new type of organic light emitting diodes (OLED). As stated, the development will create low-cost and low-power displays for mobile devices, computers and televisions. It is also possible to use the development in lighting fixtures.
Modern OLEDs have many advantages, but they also have disadvantages. One of them is low efficiency. Only one fourth of the electricity that feeds the OLED can be converted into light. You can improve the indicator with the help of rare and expensive metals, such as platinum or iridium.
OLEDs of a new type, created by German scientists in collaboration with their colleagues from the United States, are characterized by higher efficiency, and at the same time they do not use rare metals.
In OLED, light is generated by the recombination of positive and negative charge carriers. In this case, light appears only if the pair of carriers has oppositely directed spins. Otherwise, heat is generated. The presence of the mentioned metals helps to give the required value of the magnetic moment.
On the other hand, if one could wait for some time, each charge could already find a more suitable one in terms of emitting light when they collide. However, in a conventional OLED, the interaction of positive and negative charges occurs without any delay. The new LED has "waiting" conditions, which increase efficiency.
