Offshore platform for the creation of environmentally friendly hydrogen

01.07.2023

France launched the Sealhyfe offshore plant, which is designed to produce green hydrogen. The platform is capable of producing 400 kilograms of H2 molecules daily using modern technology.

Lhyfe's plant is equipped with a 1 MW cell and is installed on a special floating platform located offshore.

This is the second stage of testing this production. In the first phase, which lasted eight months, the platform was berthed in the port of Saint-Nazaire. During this time, a comparative analysis and optimization of technologies and systems was carried out.

The platform will operate autonomously, connecting to the subsea hub of the SEM-REV Centrale Nantes offshore test site via a main cable.

The company's specialists also plan to repeat the tests on the berth to compare the results and conduct additional tests in sea conditions.

Lhyfe aims to develop operational capabilities to manage platform traffic and environmental aspects, as well as validate the software and algorithms used in the green hydrogen production process.

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, ... >>

Sleep duration depends on genes 18.12.2014

Sleep duration and diabetes may be linked by genes that affect both sleep and metabolism.

It is believed that normally we should sleep an average of eight hours a day. However, exactly what is "on average" - all people are different, and someone sleeps longer, someone less. Of course, it depends on many things: how tired we are, what we ate, how our health is, etc. Obviously, the duration of sleep also depends on genes, but so far no one has such genes in our DNA. searched.

Researchers from the Center for Sleep Disorders in Boston (USA), led by Daniel Gottlieb, analyzed the genetic data of more than 50 people and compared them with the usual duration of a night's sleep for everyone. As a result, two regions in the genome were identified that could be said with great certainty that they affect how much we sleep. In an article in Molecular Psychiatry, the authors write that one of them is associated with more and the other with less sleep. But it is very rare for a gene to be associated with only one trait. Here it turned out that the "long sleep zone" also improves glucose metabolism and reduces the likelihood of attention deficit hyperactivity disorder. (Attention-Deficit Hyperactivity Disorder is a neurological-behavioral developmental disorder beginning in childhood that manifests itself as difficulty concentrating, hyperactivity, and poorly controlled impulsivity.) The 'sleep zone' is known to be associated with a high risk of depression and schizophrenia. The LiveScience portal writes briefly about the results.

The fact that too long or too short sleep accompanies various diseases has been discussed in the scientific world for a long time. For example, a year ago, an article appeared in Sleep magazine describing the harmful effects of "abnormal" sleep. According to them, if you sleep less than six or more than ten hours a day, then you, along with a nervous breakdown, may have problems with the heart, blood vessels and metabolism. There are other works on this topic, and, for example, the relationship between relatively short sleep and type XNUMX diabetes (not to mention neuropsychiatric disorders) has been repeatedly traced in various medical studies.

However, it should be remembered that in such cases they mean correlation, the coincidence of parameters, so that in fact it cannot be argued that it was the lack of sleep that caused diabetes - at least until we understand the physiological mechanism connecting them. After all, it may turn out that both obesity with diabetes and too little sleep are the result of the same mutation. And just genetic research is indispensable here.

On the other hand, it remains to be seen how exactly the aforementioned zones of long and short sleep affect its duration. Daniel Gottlieb and his colleagues believe that in the case of a zone of long sleep, it is worth paying attention to thyroid hormone (or thyroid hormone). A piece of DNA that increases sleep duration is located next to the PAX8 gene, which affects the development of the thyroid gland. Nearby regions of the genome often influence each other; in this case, this effect is supported by the fact that people with a poorly functioning thyroid gland develop increased drowsiness, while an overactive gland and too high a level of thyroid hormone are accompanied by insomnia. So far, these are only assumptions that require direct experimental verification. The authors of the work themselves emphasize that, when exploring the genetic causes of too long or too short sleep, it is always worth remembering how strong the influence of external factors is here, from ecology to our habits.
