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 ... >>

Scientists brought together identically charged particles 21.02.2023

It is likely that the charged particles are reluctant to react with each other because they are repelled electrostatically. However, scientists have discovered how to bring them closer. The new method can speed up the reaction by up to 5 million times, according to the Institute of Physical Chemistry of the Polish Academy of Sciences.

Thanks to the research of an international group with the participation of Poles, the rate of chemical reactions in aqueous solutions can be controlled in a new way. It is enough to add particles of opposite charge to the solution, which will force the previously disgusting reagents to approach each other. The use of molecules with a high charge density can speed up the reaction up to 5 million times.

The synthesis of new compounds or the production of materials is extremely complex at the molecular level.

Two molecules with the same charge repel each other, so they rarely react with each other. This reaction may take days, weeks, or even longer. However, this time can be greatly reduced by using the right conditions or by adding different chemicals. Examples include natural catalysts such as enzymes or synthetic nanozymes that mimic natural or metal based catalysts commonly used in industry. Regardless of the type of catalyst, each of them accelerates only selected chemical reactions.

The study concerned the reaction between negatively charged molecules of coenzyme A in the aquatic environment. These particles repel each other.

Although coenzyme A molecules interact with each other, their interaction is much slower in water than in organic solvents. The scientists investigated the effect of adding compounds with opposite charges to speed up the reaction.

The influence of molecules of different sizes and charge values, such as ions, amphiphilic molecules, monomers, oligomers, polymers, and even micelles, was also tested.

When the corresponding positively charged micelles were introduced into the system, the reaction rate increased by a factor of 5 million. Monomers, oligomers and polymers speed up the reaction by 103-105 times, while ions or amphiphilic molecules "only" about a thousand times.

The action of coenzyme A (CoA) or methylmaleimide-substituted coenzyme A (CoA-M) on compounds with opposite charges disrupts the repulsion between negatively charged CoA and CoA-M molecules. Under certain conditions, the convergence of negatively charged particles of a certain concentration occurs. The added compound shields the repulsive forces of the molecules, making this process a special case of catalysis.

The scientists also tested this phenomenon with DNA hybridization, which is an ion-sensitive process. This process was chosen to determine if the proposed effect works for more complex reactions. It turned out that here, too, positively charged compounds significantly accelerate the rate of hybridization.
