nitrogen diamond

17.10.2004

A group of scientists led by Mikhail Yeremets from the Max Planck Institute of Chemistry (Germany) obtained the polymer nitrogen predicted about ten years ago.

Enclosing nitrogen in a microscopic diamond chamber with a piston, they subjected it to a pressure of a million atmospheres, while heating it with a laser to 1725 degrees Celsius. The nitrogen sample turned into a transparent crystal.

X-ray diffraction analysis showed that this is polymeric nitrogen, similar both in appearance and in molecular structure to diamond.

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, ... >>

Economical biofuel from cellulose 27.06.2015

A bright dream of biotechnologists is an economical biofuel from cellulose. Of course, sawdust and other garbage are supposed to be used for biofuel, and not timber. Cellulose, as you know, is a polymer of glucose, however, it is beta-glucose, not alpha-glucose, which is part of sugar and starch, but bacteria or yeast fungi may well make some alcohols or other energetically valuable molecules from it. It would be much more profitable than spending potential food raw materials on fuel. However, it is difficult to break down cellulose into monomers; it is not for nothing that plant mass and wood are malnourished, unlike starchy tubers. This is the bottleneck on the way to biofuels.

But some people in nature eat wood, like some bacteria. And if they eat, then they know how to break down cellulose. Aerobic (oxygen-loving) microorganisms do this with the help of free enzyme molecules, while anaerobic, living in an oxygen-free environment, use enzyme complexes called "cellulosomes". Cellulase enzymes, which cleave bonds between glucose molecules, and specific proteins that attach to cellulose, are assembled into a construct that is significantly more efficient than free enzymes.

Recently it has been shown that the activity of cellulases is significantly enhanced by other enzymes, lytic polysaccharide monooxygenases - LPMO. But these enzymes are available only in aerobic bacteria (which is understandable: oxygen is needed to carry out the redox reaction).

Researchers from the Weizmann Institute (Israel) have managed to combine single molecules of cellulases and LPMO of the aerobic bacterium Thermobifida fusca into a cellulosome. Proteins were combined "in the Lego principle," as the authors of the article put it. But it would be more accurate to say that all the necessary proteins - cellulases, LPMO and the cellulose binding site - were genetically engineered with connectors borrowed from proteins of anaerobic bacteria that can assemble into cellulosomes. The connectors were chosen so that the complex included one molecule of each of the proteins. The activity of modified proteins, taken separately, did not change compared to the initial one, but cellulosomes containing LPMO cleaved cellulose 1,6 times better than a mixture of free-floating proteins, and 2,6 times better than a cellulase solution without LMPO.

Israeli scientists will not stop there: they plan to include enzymes that break down lignin into new designer cellulosomes. And you get a multi-enzyme complex that turns solid wood into a solution of sugars and phenol derivatives.
