The strongest material

14.05.2018

Previously it was believed that the strongest material was spider silk, and the best building materials were steel, ceramic and glass.

Even though technology is advancing rapidly, it is difficult for researchers to keep up with nature. Recently, scientists have been trying to replicate the architecture of natural materials at the nanoscale in order to create a more durable material. For example, by studying the strong, rigid cell wall layer of wood, which is made up of cellulose nanofibrils, the researchers tried to create strong macroscopic materials. However, weak adhesion and incompatibility of the components did not allow scientists to realize the idea.

Researchers at the American Chemical Society have tried to overcome these limitations. The team used inkjet technology to perfectly organize the macroscale fibers. Even the weakest fiber they made with this method was stronger than other cellulose nanofibers known before. And most importantly, macroscale fibers were stronger than metal, alloys and fiberglass and eight times stiffer than spider silk dragline, which is the gold standard for the strength of lightweight biopolymers.

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, ... >>

Cities will become cleaner 27.11.2000

Japanese scientists are working on a project whose goal is to ensure that the streets of the future themselves cleanse the atmosphere of harmful impurities contained in car exhaust gases.

According to Deutsche Welle, a new road surface developed by Mitsubishi engineers is being tested in Westminster, London. It is a concrete slab, on the outer surface of which a centimeter layer of a special composition containing titanium dioxide is applied.

This substance serves as a catalyst, in the presence of which the toxic oxides of nitrogen contained in the exhaust gases decompose in bright sunlight into harmless components - oxygen and nitrogen.

The effectiveness of the miracle coating was proven during the first series of experiments in the city of Osaka. Tests in London are designed to confirm that the new composition retains its effectiveness for a long time.
