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 ... >>

Efficient Oil Spill Cleanup 14.10.2012

Researchers Mike Chang and Zuepei Yuan point out that the current methods of cleaning up oil slicks, which were used, for example, to clean up the consequences of a deep-sea disaster in 2010, are in fact low-tech, decades outdated and have many disadvantages. The absorbents used, such as corncobs and straw, absorb only five times their weight, not only oil, but also water. After that, they become industrial waste, which require incineration or disposal in special landfills.

The scientists' solution is a polymeric material that converts the stain into a soft, oily gel that is dense enough to be mechanically collected and transported. In addition, the gel is amenable to liquefaction and subsequent purification similar to conventional crude oil. One kilogram of this substance can absorb about 40 liters of crude oil. At the current market price of crude oil of about $100 per barrel, the cost of this collection method would be only about $15.

The publication of the authors describes a new approach that will comprehensively solve the problem of oil slicks. The technology focuses on a cross-linked polyalkene trimer (x-OS-DVB) containing 1-octene, styrene and divinylbenzene, a superabsorbent petroleum polymer with aliphatic and amino acid compounds. The combination of selective oil absorption (i.e. without water) with high mechanical strength ensures buoyancy, reliability and ease of collection from the water surface. The collected oil gel, consisting of 98% oil and 2% x-OS-DVB, is suitable for conventional oil refining processes - economical, waste-free and with a very low percentage of harmful emissions. In addition, polyalkene is one of the cheapest polymers, the production of which is quite simple to set up around the world.

Overall, this new cost-effective technology can significantly reduce the environmental impact of oil slicks.
