Making diamonds out of peanut butter

22.07.2020

Scientists from the Bayerisches Geoinstitut (Bavarian Research Institute for Geophysics and Geochemistry) were able to make a laboratory simulation of the conditions of the Earth's lower mantle. This part is located under the asthenosphere, where at a depth of 2900 kilometers the pressure is 1,3 million times higher than atmospheric pressure. As a result of the experiment, the researchers found innovative ways to produce diamonds.

According to one theory, diamonds are formed from carbon under very high pressure. Almost all foods contain carbon, so the researchers were able to create an artificial diamond in the laboratory from ordinary peanut butter. However, the hydrogen, which is bound to carbon in peanut butter, greatly complicates the process, and therefore, even under the most favorable circumstances, the transformation is slow: it takes several weeks to produce a diamond 2-3 millimeters in size. However, the production of artificial diamonds may be very promising for their industrial applications.

Now scientists are trying to find out whether it is possible to obtain artificial diamonds with different properties. For example, compounds of diamonds with boron could greatly improve the properties of electronic semiconductors, which are prone to overheating.

In addition, using other properties of carbon, a new look could be obtained. For example, electronic semiconductors that are prone to overheating could be improved, and using other carbon structures, one could even obtain a new type of superhard diamond - stronger than any currently known material.

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, ... >>

Windmills - scrapped 10.07.2010

On the territory of Germany, from the Alps to the North Sea, more than 20 thousand wind power generators are now operating. This is a relatively new technique, but from 2020 it will begin to deplete its resource and there will be a problem of recycling old windmills. Reinforced concrete supports, generators and various metal parts are easy to reuse, but what about rotor blades made of fiberglass?

After 2020, 15 thousand blades will have to be replaced annually. They consist of a hardened polymer resin stuffed with fiberglass for strength. Burying in landfills is prohibited by law, burning - toxic gases are obtained, which are too expensive to capture with special filters.

In addition, melting glass clogs the grates of incinerators. It is possible to melt down crushed fiberglass into other products, such as garden benches, but Germany doesn't need that many benches.

A way out of the situation is proposed by the Swiss company "Holzim", a cement manufacturer. It turned out that crushed fiberglass can replace part of the fuel in clinker kilns. Temperatures up to 2000 degrees develop in the oven and all poisons burn out. In addition, melting fiberglass replaces part of the sand in the cement mixture - after all, this is the same silicon dioxide.
