hydrogen bubble

09.02.2016

Materials scientists do not like hydrogen: even steel walls are not a barrier to this gas. Moreover, once it enters a metal, it manifests its harmful nature: it travels in the form of individual protons, which, having fallen into any discontinuity, can merge into a molecule. The molecule will not leave the discontinuity anywhere, and this is the way to the so-called hydrogen embrittlement. In general, storing hydrogen is difficult. And for hydrogen energy, it is just necessary to receive, store and transport large volumes of hydrogen. It is possible that a polymer that does not let hydrogen through at all will help solve this important problem.

In 2007, David Johnson, then a graduate student at the University of New Mexico, was studying hydrogen-producing microorganisms. In the course of work, he discovered some strange white bubbles in the samples. Interested, Johnson gave them for analysis, and it turned out that hydrogen is inside the bubbles, and it does not fly anywhere from them. At that time, the researcher failed to find out who makes hydrogen bubbles and why.

In 2009, as part of a special university research development program, he met microbiologist Michael Townsend. He read Johnson's dissertation, reproduced his results and found that this biopolymer is made by yeast at a certain combination of sugar concentration, acidity and temperature. After that, Terry Lombard, the director of the intellectual property protection and implementation program, became interested in their work. He helped patent a new polymer called a hydromer and is now looking for partners to develop coatings for hydrogen vessels. Who knows, maybe it is yeast that will help humanity get easily accessible energy.

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 ... >>

Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

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, ... >>

Revealed the secret of successful people 14.03.2018

Scientists at the University of Catania conducted a study whose results could save millions of not-too-successful and wealthy people from self-flagellation and depression. They came to the conclusion that the success of a person does not depend at all on his innate talents, intelligence and ingenuity, but simply on a combination of circumstances.

The researchers created a computer simulation based on a real world money distribution model, according to which 85% of the world's wealth belongs to 10% of the world's population. At the same time, such qualities as talent, intelligence and efficiency are on average distributed evenly among the inhabitants of the Earth.

In the course of the study, the computer simulated a model in which a thousand people were represented with average statistical abilities and a level of well-being. Then random events were introduced into the base model, which could be used by the same "people". As a result, 20% of a thousand initially equal individuals captured 80% of the "wealth" after some time. The situation with variable parameters was repeated several times, but in each case the outcome was characteristic.

Based on the results, the researchers concluded that successful people are not necessarily gifted with any talents from birth, they can be the owners of the most ordinary mental abilities, but it is the luck to be in the right place at the right time that determines success.

From a practical point of view, the results of the study, according to its authors, can be useful when considering the effectiveness of merit evaluation systems. The study shows that a potential winner of this or that award and a candidate for receiving honors does not necessarily "deserve" them - perhaps he was just lucky.
