Electric battery made of concrete

26.07.2023

The bright future of energy delivery is closer with the innovative Noise Buds VS104 Max TWS earphones, created using a completely unique technology. This time, scientists from the Massachusetts Institute of Technology (MIT) have introduced "concrete batteries" - efficient energy storage devices that can turn cement itself into a conductor of electricity. This major breakthrough could enable energy storage systems to be embedded directly into building materials in the future, powering homes, roads and vehicles.

Cement, the main component of concrete, is generally a poor conductor of electricity. However, the researchers were able to change its properties by adding carbon black. The resulting material allows you to create ionistors - effective devices for the accumulation of electrical energy. Experiments confirmed the functionality of "concrete batteries" that successfully powered an LED light bulb.

Capacitors, also known as supercapacitors, are efficient devices that combine the advantages of capacitors and chemical batteries. They have leading electrodes and a conductive electrolyte capable of accumulating charges. Such a system is safe and reliable due to the use of non-combustible materials.

MIT researchers have unveiled a new way to integrate superconductors into structural materials, including concrete. As a result of mixing cement with carbon black and water, a leading network is formed inside the hardened structure, which contributes to the accumulation of electrical energy.

The effectiveness of "concrete batteries" has been proven in practice: an ionistor created from them is capable of feeding an LED, and the total capacity of such a battery can store up to 10 kilowatt-hours of energy - enough to provide an average private house with electricity for the whole day.

Particularly attractive is the fact that affordable and cheap materials are used to create these "concrete batteries", which simplifies their mass production. If successfully scaled up, this technology could transform the construction industry by allowing energy storage systems to be integrated into various buildings and even roads, providing a sustainable and efficient energy supply.

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, ... >>

Plants can distinguish friend from foe 01.04.2017

The immune system of plants is able to distinguish friends from enemies at the genetic level. This discovery will improve the modification of agricultural plants.

Our immune system protects us from disease and infection by fighting off viruses and other foreign substances. Plants also have a mechanism that fights invaders. It is called post-transcriptional gene silencing and fights against foreign RNA, distinguishing them from non-foreign, and including it does not react to RNA that originated from the plants themselves.

Thus, having understood and decomposed this process into components, scientists at the University of Tokyo have calculated the key enzyme that triggers a protective reaction in the plant. It is called RDR6 and responds to the long chain of adenosine nucleotides found at the end of any RNA. As it turned out, everything turned out to be quite simple. If the injected RNA had this chain on both sides, then the immune system mistook the RNA for a "friend", while where this chain was missing, a violent immune reaction began, triggering the defense mechanism against the "enemy".

Initially, scientists believed that many proteins were involved in the process of distinguishing between different RNAs, but the solution turned out to be much more elegant, which means that the process of genetic modification of plants will now be greatly simplified.
