The largest dinosaurs

02.05.2000

Argentine paleontologists have found fragments of a skeleton in Patagonia that belonged to the largest dinosaur known so far. This herbivorous giant lived 105 million years ago, weighed twice as much as a large elephant (nine tons) and was 47-50 meters long. This is 5-8 meters more than the Argentinosaurus, which was still considered the largest of the pangolins. True, the Argentinosaurus was ten times heavier.

Giant bones - a cervical vertebra two meters long and a femur - were found by peasants 1000 kilometers southwest of Buenos Aires and scientists were called. Excavations are not over yet, and the giant has not yet received an official scientific name. Meanwhile, the remains of an aquatic dinosaur resembling a giraffe have been found in the Sahara. He was 18 meters high (of which the neck was 12), and weighed 60 tons.

The lizard is named Sauroposeidon. Paleontologists who found the giant's neck vertebrae first mistook them for fossilized tree trunks.

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, ... >>

Extraction of clean water from fog 31.08.2023

A group of engineers from the Institute for Polymer Research at the Max Planck Society and ETH Zurich have successfully developed an innovative method for extracting potable water from fog. This technology can be applied in areas where fresh water sources are scarce, such as regions with limited access to spring or rain water.

Engineers have created a special fine-mesh mesh made from metal wire and coated with a combination of polymers and titanium oxide. This design ensures that moisture is optimally collected on the surface of the mesh, and then the water flows efficiently into the collection tank, preventing it from being blown away by the wind. Titanium oxide acts as a chemical catalyst, decomposing organic contaminants in water droplets and neutralizing them.

This technology requires minimal maintenance and does not depend on the use of electricity, and sunlight is sufficient for its operation. Regeneration of titanium oxide periodically requires ultraviolet irradiation, but this process is economical: just half an hour of sunlight will provide catalyst activity for 24 hours.

The researchers tested the new system both in the laboratory and in a small pilot plant in Zurich. They were able to capture 8% of the moisture from the artificial fog and remove 94% of the organic compounds added to the fog. Among the contaminants removed were tiny droplets of diesel fuel and substances such as the hormone-active chemical bisphenol A.

In arid regions, people are already using metal nets to collect water from fog. The droplets condense on the grid, flow down and can be collected. Collectors with an area of ​​only a few square meters, installed in places with dense fog, are capable of collecting several hundred liters of water.

However, there is a problem of air pollution: dangerous and toxic substances can accumulate in the water droplets of the fog. In the ranks of large cities, air pollution is so significant that water collected from mist without prior purification may be unsuitable for drinking or cooking. A new discovery addresses this challenge by providing a safe and affordable source of clean drinking water.
