Subminiature TransferJet Module

15.03.2014

Specialists of the Japanese company Toshiba have created the world's smallest wireless communication module and an antenna for it in the form of a flexible printed circuit board. These components are compatible with TransferJet short range wireless technology.

The operation of TransferJet is based on the principle of a resonant transformer. The transmission speed reaches 375 Mbps. The developer expects that TransferJet technology will be widely used in mobile devices due to low power consumption, high speed and exceptional ease of use. The company believes that the growing demand for high-speed wireless communication between electronic devices will increase the demand for modules and antennas (essentially resonant transformer windings) that can be easily integrated into consumer electronics devices.

The module in question measures 4,8 x 4,8 x 1,0mm and the PCB-style antenna is only 0,12mm thick. The key to miniaturization was the volumetric integration of the chip onto the module substrate and the use of molecular bonding technology. The manufacturer notes that with this, measures were taken to reduce parasitic capacitance, which could adversely affect the transmission of a signal with a spectrum of 560 MHz.

Introductory module samples are already available, flexible antenna samples will appear this month.

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, ... >>

Stem cells help cure alcoholism 20.03.2018

Researchers at the University of Chile found that a single dose of human mesenchymal stem cells (MSCs) significantly reduced voluntary alcohol intake in alcohol-addicted rats.

Chronic drug use, including alcohol, cocaine, and opiates, is associated with increased inflammation of nerve tissue. Other studies (in both humans and rats) have also shown that this inflammation can increase alcohol cravings.

Because mesenchymal stem cells are relatively large, they typically do not reach the brain when given intravenously. In the new experiment, the team reduced the size of the cells by up to 75%, allowing them to better enter the brain. The tool was tested on specially bred rats consuming large amounts of alcohol.

As a result, a single small dose of MSCs was able to reduce brain inflammation and oxidative stress in animals that consumed chronic alcohol. Within 48 hours, the rats reduced their alcohol consumption by a record 90%. In addition, alcohol-induced neuroinflammation was significantly reduced. The effect lasted 3 to 5 weeks after the injection.

The next step is to move on to human clinical trials, verify the results, and develop a new effective treatment for alcoholism.
