Fast trains are not the best

20.10.2015

The London Underground is officially known as the London Underground, but is known worldwide as The Tube. The London Underground is considered to be the oldest system of rapid public transport, which includes the world's first underground railway and the first line on which underground electric trains went.

An experiment has recently begun on the London Underground that could give the Underground yet another "very first" title. An inverter generator is installed there, which converts the train's braking energy into electricity, enough to light the station (in this case, Holborn) for two days a week.

During a five-week test, the system captured a megawatt-hour of electricity, enough to power more than 100 homes. If the technology were extended to the entire Pipe, the savings would amount to £6 million a year. In addition, regenerative braking generates less heat than conventional braking, so the tunnels stay cool longer, reducing climate control costs.

Economic factors are very important for the development of Truba, which plans to increase passenger traffic by 30% with the growth of the city. However, as a recent study showed, the excessive efficiency of the subway turns into congestion of surface transport.

A group of mathematicians and programmers from Switzerland, France, the United States and Scotland built a model that looked at the correlation between underground and elevated transport systems in New York and London. It turned out that London trains run too fast, which creates optimal conditions for traffic jams at the top, as traffic on the outskirts is faster than in the city center. In New York, trains are slower, which, combined with a more centralized subway system than in London, results in fewer traffic jams.

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, ... >>

Flexible and translucent perovskite LED 16.01.2019

In recent years, the study of the properties and the search for applied properties of perovskites, calcium titanate minerals, first found in the Urals about 180 years ago, is gaining popularity among scientists. The developers of solar panels (photocells) made of perovskite went the furthest. The use of sputtering from this material makes it possible to create curved and translucent panels with an efficiency that is noticeably higher than that of conventional silicon. But perovskites, under certain conditions, can also emit photons. It was the combination of the light-emitting properties of this material with flexibility and partial transparency that allowed Korean scientists to create a flexible and translucent perovskite LED.

A group of scientists from South Korea's Ulsan National Institute of Science and Technology (UNIST) has unveiled a perovskite-based LED. The developers also created a methodology and tools for studying the bending reliability of LEDs. Experimental development without destruction withstands repeated bending with a radius of up to 2,5 mm. This allows us to hope for the creation of folding displays on screens using PeLED (Perovskite Light Emitting Diode), if any ever appear.

Experienced perovskite LED has good power, brightness and pure color spectrum. Its transparency is 50%. In order for all LED components to be translucent, conductive metal tracks had to be abandoned, which were replaced with silver nanotracks. By the way, the perovskite LED continued to glow brightly both during bends across the plane and when twisted into a spiral.

In the future, scientists plan to study the reliability of perovskites as light-emitting diodes in the form of thin-film structures. This material quickly degrades in the open air (when interacting with oxygen) and in the process of moistening. Experiments should clarify the prospects of using this material for LED production.
