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 ... >>
The threat of space debris to the Earth's magnetic field
01.05.2024
More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>
Solidification of bulk substances
30.04.2024
There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>
Random news from the Archive Sodium-ion batteries
22.03.2021
Today, lithium-ion batteries dominate the market for efficient energy storage systems, but the latest sodium-ion batteries are already poised to replace them in data centers, telecommunications, and home and energy backup systems.
Sodium-ion batteries promise to be cheaper, safer and more environmentally friendly than lithium-ion. They do not contain metals and substances hazardous to human health either in the cathodes or in the electrolyte, and the reserves of sodium in the earth's crust are thousands of times greater than those of lithium. The only thing in which sodium-ion batteries are inferior to lithium ones is about half the specific energy storage density.
So, if commercial lithium-containing batteries can store an average of 285 Wh / kg, then promising sodium-ion batteries promise up to 140 Wh / kg. But this only means that sodium-ion batteries are unprofitable in small devices such as smartphones, while this is not critical for backup power supplies. For large systems, it is important that the cost of sodium-ion batteries will be 10-20% less than lithium-ion, and over time this difference will only increase.
Prototypes of new sodium ion cells can achieve energy densities in excess of 140 Wh/kg. At the same time, a number of studies are underway that promise to bring the capacity of sodium-ion batteries closer to 200 Wh / kg, but this will be the next stage in the development of such battery cells.
