Ecological synthesis of urea

06.10.2023

Scientists from the University of Queensland (QUT) have unveiled an environmentally friendly method for synthesizing the vital agricultural fertilizer urea. This method allows the production of urea at room temperature with minimal energy consumption, in contrast to the traditional synthesis process using large amounts of energy.

Dr Junxian Liu, the study's lead author, together with Professor Yuantong Gu and Associate Professor Liangzhi Kou from the School of Engineering, Medicine and Technology, have discovered an effective way to create urea, an important nitrogen fertilizer that supports about 27% of global agriculture. Urea is also used in pharmaceuticals, cosmetics and plastics production.

Unlike the traditional industrial process, which involves high temperatures and pressure, the new method offers urea synthesis at room temperature and atmospheric pressure. This is achieved through a chemical reaction between nitrogen and carbon monoxide using a graphene-based catalyst.

This approach significantly reduces energy consumption compared to traditional methods, making it a promising advance for urea and fertilizer production in general.

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 glasses and implantable chips instead of smartphones 01.06.2022

Pekka Lundmark, CEO of telecommunications equipment company Nokia, said that the commercial use of the sixth generation (6G) communication networks will begin in 2030. At the same time, he noted that by that time, most likely, many people will refuse to use smartphones, preferring wearable electronics and implantable chips.

During a speech at the World Economic Forum in Davos, Lundmark said he expects commercial use of 6G around 2030. He noted that even before that, people are likely to abandon smartphones and switch to smart glasses and other similar devices that can connect to the Internet and interact with each other. Moreover, some of these devices will be implanted in the human body.

“By then, the smartphone as we know it today will definitely no longer be the most common interface. Many of these things will be built directly into our bodies,” Lundmark said.

He did not specify what exactly he meant, but it is likely that we are talking about electronic implants, such as those developed by Elon Musk's company Neuralink. In a broader sense, we can talk about chips designed to be implanted in fingers or other parts of the body.

Lundmark also said that by 2030 there will be a "digital twin of everything", which will require "tremendous computing power". According to him, in order to transmit data in the Metaverse, the networks must be 100 or even 1000 times faster than we have today.
