Dog's paw will test the reliability of the car

07.12.2019

A 3D-printed paw will allow you to experiment with the paintwork of cars, checking the level of wear.

Engineers used a real Labrador Yogi from the National Guide Dog Breeding Center to create the artificial paw. The dog jumped into the trunk of the new Land Rover Defender and jumped out of it, and each action of the dog was recorded using special pressure calculation technology - the collected data formed the basis of RoboYogi.

The paw of a 9-year-old Labrador was taken as a model, based on it being 3D printed copies on springs. Artificial paw claws distribute pressure evenly over the bumper, simulating the claws and paw of a medium-sized dog. RoboYogi is used for 5000 color check cycles - the artificial paw scratches the car body 10 times in random places, and then on one specific side, after which the process is repeated.

Based on the results of tests using RoboYogi, the engineers of the British automaker came to the conclusion that the paintwork of Land Rover vehicles can easily withstand contact with animal paws for 10 years of operation of the car.

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, ... >>

Earth's composition differs from potentially habitable planets 26.09.2015

Scientists from the University of Porto (Portugal) said that the Earth is an exception among potentially habitable planets in our galaxy.

The researchers drew attention to the stars, the mass and radius of which are almost the same as the sun, and in their habitable zone there are planets where water is present in the form of a liquid. Iron and other metals in the composition of such stars turned out to be less than that of the luminaries, around which only uninhabited planets circulate.

As a result, scientists concluded that because the planets are similar in chemical composition to their stars, celestial bodies from the habitable zone usually contain less metals than in the bowels of the Earth or the Sun. As a rule, massive bodies with a gaseous envelope rotate around iron-rich stars.

Differences in chemical composition between the Earth and most planets in the habitable zone, the researchers explain the fact that the latter, most likely, much older. Iron and other heavy elements are formed in the explosions of luminaries and disperse through interstellar space.

When the Milky Way was younger, there were fewer such explosions, as well as iron in ancient habitable exoplanets. If the existence of inhabited planets is more characteristic of stars poor in metals, then at the present stage of the life of a galaxy they are formed much less frequently.

However, stars exist for a long time and ancient planets with favorable conditions for the emergence of life are still present. The Earth, however, is an exception among potentially habitable planets in our galaxy, radically different from them in its chemical composition.
