Getting energy from carbon dioxide

10.06.2019

South Korean scientists have developed an innovative way to generate energy from carbon dioxide. The discovery will provide mankind with access to cheap electricity and help solve the problem of global warming.

As Kim Geun-tae, a leading researcher at the Ulsan Institute of Science and Technology, explained, the discovery makes it possible to obtain electricity and pure hydrogen from a medium consisting of water, carbon dioxide dissolved in it, and two catalysts. "The chemical and electrochemical reactions that take place in such a system are simple enough that the process can be easily used commercially," Professor Kim explained. According to him, thanks to this method, the cost of converting a ton of carbon dioxide into useful energy will be only $200.

"By dissolving carbon dioxide in water, we were able to find a new use for it," the professor comments on the discovery. Several local chemical companies and smelters are already interested in the innovative chemical process, as it can solve the problem of carbon dioxide emissions in these plants.

It is planned that this method will be implemented at South Korean industrial facilities after completion of field trials. In addition to generating cheap electricity, the hydrogen generated by the chemical reaction can be used as fuel in hydrogen filling stations for cars. It is also expected that carbon dioxide conversion technology will help in the fight against global warming, one of the causes of which is the growth of greenhouse gas emissions.

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, ... >>

water planet 30.11.2012

Pictures taken by the Hubble Space Telescope have made it possible to find another distant planet. Named GJ 1214b, it orbits a red dwarf about 40 light-years from Earth. Although the dwarf is dim, it is only two million kilometers from the planet, so the temperature on its surface is 230 degrees Celsius.

As the Hubble equipment showed, the atmosphere consists of water vapor. And judging by the average density of the newly discovered celestial body, the entire planet GJ 1214b consists mainly of water. Since its diameter is 2,7 times that of the earth, gravity is also stronger there, so that the water does not evaporate too violently. Under these conditions, astrophysicists say, such forms of water, unusual for us, as hot ice and superfluid water, can exist there.
