Freeze-resistant lithium-polymer batteries from EEMB

27.05.2015

EEMB, a well-known manufacturer of lithium batteries and batteries, has released a series of frost-resistant batteries that provide discharge in the temperature range of -40...+45°C (it is possible to use up to +60°C with partial loss of capacity).

The new series of lithium-polymer batteries has several patents and is characterized by improved performance at low temperatures. Batteries have increased capacity stability, increased safety and extended life cycle. It's no secret that at low temperatures, all batteries of any manufacturer lose their nominal capacity. The new series is no exception, but this loss is only 25%, which is an insignificant value considering the temperature of -40°C and at the same time the cost of the batteries is quite low. You can distinguish a new series of batteries from "ordinary" ones by the presence of LC symbols at the end of the name, for example: LP103454LC.

At the request of the end user, it is possible to order batteries with the required parameters (capacity / voltage) and dimensions; protection board can be installed. When determining your own parameters, you should be guided by the value of specific energy density, which should not exceed 100-115 Ah/dm3.

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, ... >>

Warm nanoparticles stimulate the brain 18.03.2015

Nanoparticles heated by a magnetic field can replace conventional brain implants with electrodes and external power sources.

Many have heard about the methods of transcranial brain stimulation, when a particular area of the cerebral cortex is affected by a magnetic field or a weak electric current without any surgical intervention. Last year, an article was published in Science stating that using an external magnetic field can improve memory, and in 2013, researchers from Ben-Gurion University were able to use it to rid several smokers of their bad habit - at least for six months. .

But purely transcranial methods are not highly specific. On the other hand, there are invasive methods, when we implant electrodes in the brain that selectively act on certain groups of cells. With the help of such electrodes, it is possible, for example, to suppress muscle tremor in patients with Parkinson's syndrome, but the inconvenience of this method is obvious: surgical intervention plus the need for an external power source.

Polina Anikeeva of the Massachusetts Institute of Technology and her lab have developed an ingenious method that eliminates the need for a permanent brain implant while still providing stimulation specificity. Its essence is that iron oxide nanoparticles are introduced into the brain, which do not carry any drugs, but can be heated in a magnetic field. When heated, they stimulate capsaicin receptors on cell membranes. Capsaicin is an alkaloid that provides a burning taste to capsicum, receptor proteins for it (TRPV1) are found in different cells, including some brain neurons. However, in the absence of receptors, it is possible to force the cell to synthesize them by genetic engineering methods - which was done in this case.

Proteins sensitive to capsaicin react to heated nanoparticles and open an ion channel in the membrane, as a result, the cell is excited and generates an impulse. Usually, such hot nanoparticles are considered as an antitumor agent that allows them to kill cancer cells, but this time the researchers were interested in just exciting the cells without killing them. By adjusting the strength of the magnetic field, you can achieve the desired temperature of the particles and the desired effect. They themselves, being chemically completely inert with respect to living tissue, can remain for quite a long time where they were introduced. As the authors of the work write in their article in Science, their method made it possible to stimulate an area of the midbrain in mice called the ventral tegmental region (which, by the way, is involved in the reinforcement system and is involved in the formation of drug addiction) for a month.

In the future, nanoparticles with a magnetic field can be used as a wireless and "long-playing" neuron stimulator, which would allow solving a variety of research and medical problems. Of course, practical application is still far away, but we have a fundamental proof that such a method is possible and works - and this is already quite a lot.
