New wireless power transmission system

30.12.2013

Murata Manufacturing has preview samples of a new system for wireless power transmission. This system, which is based on the effect of "DC resonance", was introduced in the spring.

Evaluation samples were provided free of charge to members of the Wireless Power Management Consortium (WPM-c).

According to the source, the use of the effect of "resonance direct current" can radically reduce the size of the system. The transmitting and receiving modules in the case of a trial sample have dimensions of 10 x 22 x 2,5 mm and 8 x 13 x 1,7 mm, respectively. Operating at a frequency of about 20 MHz, such a pair provides a power transfer of 0,5 watts. The transmitter module can be powered, for example, from a USB 2.0 port.

Murata is said to be looking at 3W, 10W and 30W systems running at 6,78MHz. One of the applications of the Murata development is the wireless charging of batteries of mobile devices.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

E. coli passes on experience through generations 02.12.2023

A study conducted by scientists from the University of Texas and the University of Delaware reveals the amazing ability of the Escherichia coli bacterium to preserve and pass on experiences to subsequent generations. These microorganisms, although they do not have a brain, are able to remember information about the environment and then use it to their advantage.

Escherichia coli bacteria have demonstrated the ability to preserve and transmit experience across generations, which opens new perspectives in understanding the adaptation and evolution of microorganisms. This discovery could have important implications for understanding biological mechanisms and their role in the ecosystem.

Molecular biologist Souvik Bhattacharya of Utah, the lead researcher, emphasized that bacteria, when frequently exposed to a particular environment, can retain information about that external influence. Scientists conducted tests with E. coli, studying their ability to form a mass to migrate under certain conditions.

The study revealed that intracellular iron concentration becomes a key factor influencing the speed and efficiency of bacterial migration. Low iron levels were associated with faster and more efficient movement, while higher levels promoted a stationary lifestyle.

Surprisingly, this behavior was passed on to several generations of daughter cells created by dividing the mother cells. Although this “iron” memory was lost by the seventh generation, scientists were able to restore it through artificial stimulation.

By analyzing more than 10 bacterial swarms, the study highlights the phenomenon of experience transfer in the microbial world. Scientific discoveries in this area may have an impact on understanding the evolution and adaptation of microbes to changing environmental conditions.
