The main component of interstellar ionized gas has been obtained

01.08.2017

Triatomic hydrogen (Trihydrogen, H3+) has played and is playing the most important role in astrochemistry, in the processes by which new stars are formed and by which the Universe has acquired the form in which we see it today. Specialized astronomical instruments allow scientists to see traces of triatomic hydrogen everywhere in space, but the processes by which these molecules are produced in large quantities remained a mystery to scientists until very recently.

Using powerful lasers, scientists from the University of Michigan have solved the mystery of the formation of triatomic hydrogen by reproducing in the laboratory the mechanism of the formation of these molecules that fill the space from the center of our galaxy to the Earth's ionosphere.

To reproduce the process of formation of triatomic hydrogen, scientists used a strong field laser (strong-field laser), the light from which served as a kind of catalyst for the transformation reaction. And to track the ongoing processes, femtosecond laser light pulses were used, which made it possible to track the fast processes of the formation of chemical bonds of H3+ molecules.

"We found that the main 'actor' in the transformation reactions is the ordinary hydrogen molecule H2. However, this reaction follows a completely new 'path', about which we knew almost nothing until recently," says Professor Marcos Dantus (Marcos Dantus ), - "Further studies of this issue will allow us to find explanations for the occasionally improbable and inexplicable chemical reactions that we observe."

One of the reasons why ionic transformation reactions are poorly understood is that all processes occur in such short time intervals that it is even difficult to measure. The entire reaction, including the moments of splitting and the formation of three chemical bonds, takes from 100 to 240 femtoseconds. This is less than what is required for a flying bullet to cover a distance equal to the diameter of one atom.

The process by which an H2 molecule gains an extra proton to become the triatomic hydrogen H3+ is strikingly unusual. The neutral hydrogen molecule H2, resulting from the ionization of an organic compound molecule, remains in close proximity to the formed ion until it "meets" one of the protons of the remaining acid base ion. After such a "meeting", the proton is extracted from the ion and the hydrogen molecule H2 itself turns into an H3+ ion.

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, ... >>

Smart mouse Cheerdots 2 with built-in ChatGPT 29.11.2023

An exciting project has appeared on the crowdfunding platform Kickstarter - a wireless mouse equipped with artificial intelligence ChatGPT. The new product is called Cheerdots 2.

Cheerdots 2 is an innovative device that combines the functionality of a wireless mouse and ChatGPT artificial intelligence. Its varied usage options make it appealing to a wide range of users, and its promised battery life underscores the technology's effectiveness.

The new device consists of two parts - a docking station with a magnetic mount and a base with a touch panel. Cheerdots 2 provides a variety of options for use: a regular mouse, voice recorder or laser pointer. There are several use cases for ChatGPT.

Using the mouse, you can record lectures or conversations, and artificial intelligence converts speech into compressed text and transmits it to your computer via Bluetooth or Wi-Fi. The smart mouse can also translate recorded text or speech into different languages, take notes, create reminders, and extract key information from conversations.

The manufacturer guarantees 20 days of battery life on a single battery charge. The price of the device is $125. Deliveries to customers are scheduled for March 2024.
