Nanoelement for soldering ready

20.08.2004

Scientists from Israel attached gold tips to the nanotransistor, and now it is easy to attach it to an electric nanocircuit.

In stories about the brilliant future of nanotechnology, the miraculous nanoparticles themselves take center stage. However, the ways of connecting them, for example, into some kind of working electrical circuit, are the subject of reflection for many learned men and women. Really, isn't it possible to manually collect billions of particles? In addition, good electrical contacts are needed, but how to attach them so that the properties for which everything is intended do not disappear?

Scientists from the Center for Nanoscience and Nanotechnology at the University of Jerusalem paved the way for solving both problems: they attached two gold particles to the ends of an extended nanocrystal with strong chemical bonds. The result is something that looks like an aerobic dumbbell.

“Thanks to chemical bonds, electric current easily passes through this structure,” says the head of the research team, Professor Uri Banin. “In addition, by sewing special molecules to the gold particles, we will be able to connect the golden ends of different dumbbells to each other. And this is self-assembly. Our method allows you to create various forms of circuits.For example, you can get tetrapods, the gold particles of which will have four bonds - a kind of network splitters."

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, ... >>

Gravity can create light 20.04.2023

Work from Swinburne University of Technology showed that under the exotic conditions of the early universe, gravitational waves could perturb space-time so violently that they spontaneously produced light.

When you sit on a swing and want to swing harder, you start moving your legs back and forth. You quickly find the right rhythm to swing at the right moment. This special kind of phenomenon is known in physics as parametric resonance. When your legs move at the resonant frequency of the system, they can transfer energy to the system, causing the swing to rise higher.

These kinds of resonances are found everywhere, and a team of researchers found that an exotic form of parametric resonance could have originated in the very early universe.

Perhaps one of the most important phenomena in the entire history of the universe was inflation. This is a hypothetical event that happened when our universe was less than a second. During inflation, the cosmos expanded to enormous proportions, becoming many orders of magnitude larger. The end of inflation must have been very chaotic as gravitational waves splashed in all directions throughout space.

Usually gravitational waves are very weak. Detectors had to be built that could measure vibrations smaller than the width of an atomic nucleus in order to detect gravitational waves passing through the Earth. But the researchers note that in the very early universe, these gravitational waves could become very strong. In those places where they were strongest, the waves could give an exceptional amount of energy.

The authors of the work calculated that this could have serious consequences for the electromagnetic field that existed at that time in the early Universe. Areas of intense gravity could wake up the electromagnetic field enough to release some of its energy as radiation, creating light.

This result gives rise to a completely new phenomenon: the generation of light only due to gravity. There are no situations in the modern universe where this can happen, but physicists have shown that the early universe was a much stranger place than one might imagine.
