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 ... >>
| Random news from the Archive The capacity of lithium-ion batteries will increase by a third
13.04.2013
The new technology allows a 30% increase in the capacity of lithium-ion batteries. The developer expects that the technology will be of interest to manufacturers of smartphones and other gadgets, as it will reduce their size and weight.
The American startup EnerG2 has started the production of electrodes from the so-called "solid carbon". It allows you to increase the capacity of a lithium-ion battery without significant design changes and the introduction of new manufacturing processes, according to Technology Review. According to representatives of EnerG2, the carbon electrode (in this case, the anode, the positive electrode in the battery) allows you to increase battery capacity by up to 30%. The EnerG2 electrode is made of carbon with an amorphous structure, in which the atoms are not ordered, unlike graphite with its crystalline structure, a traditional material for making anodes. Such a material can store 50% more energy per unit of its surface than graphite.
Lead-acid batteries and capacitor parts were the first products to use the new technology. However, both products represent relatively narrow segments compared to the lithium-ion battery market. According to EnerG2 CEO Rick Luebbe, the disadvantage of the material described is that the battery loses its capacity the first time the battery is charged. The startup managed to reduce the size of this loss to a value acceptable for the manufacture of commercial products.
It is worth considering that the cost of an anode made of solid carbon is about 20% higher compared to graphite. For this reason, this technology is unlikely to be able to afford manufacturers of batteries for electric vehicles, analysts say. As for manufacturers of electronic gadgets, they may well pay extra to make devices thinner and lighter.
In addition to batteries, EnerG2 is exploring other uses for solid carbon, including storing natural gas at lower pressures. In 2010, the company received a grant from the state in the amount of $21 million, for which, among other things, the plant was built.
Making electrodes from solid carbon is one possible way to increase battery capacity. For example, VC-backed Envia Systems and Amprius have proposed the use of silicon in electrodes, which has also led to higher capacitance. However, according to EnerG2 representatives, silicon electrodes offer fewer recharge cycles and require design changes.
