Airless tires

05.06.2019

GM and Michelin have unveiled a prototype airless passenger car tire called Uptis (Unique Puncture-proof Tire System).

Airless tires are made from a mixture of composite rubber and fiberglass polymer. This makes it possible to use such a tire at a high driving speed, which the car can develop on motorways. In most cases, earlier prototype airless tires can only be used at low speeds. The Uptis may not look as good as traditional tubeless tyres, but Michelin says they're just as comfortable to use.

More importantly, there is a very real roadmap for introducing this technology into everyday life. GM will begin testing Uptis in Michigan later in 2019 on Chevy Bolt vehicles. As expected, the finished consumer version will appear on production cars as early as 2024. The automaker did not name specific car models that will use the new tires.

Uptis airless tires offer a number of advantages. Switching to them will reduce the amount of harmful emissions in the tire production process. As for performance, they are not afraid of punctures and uneven wear. What's more, it eliminates the need for spare tires, which add weight to the vehicle and result in additional fuel consumption.

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 ... >>

Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

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, ... >>

Mother's milk and career 11.01.2008

British sociologists from the University of Bristol, following the fate of 1400 children born in Bristol between 1937 and 1939, came to the conclusion that breastfeeding later reflects well on a child's career.

Of those who were breastfed in infancy, most have climbed the social ladder compared to their parents, and of the "artists" only half have achieved this. Moreover, the chances of success in life are higher, the longer the child was not weaned. Such differences are also noted within the same family: if one child was breast-fed, and the other with substitutes, then greater success in life, as a rule, awaits the first.

The reasons for this phenomenon are unclear, although it has been observed that naturally fed children have a slightly higher IQ.
