wood-based nanofiber

21.08.2017

A global push among automakers to make ever lighter vehicles is prompting some manufacturers in Japan to turn to what seems like an unlikely substitute for steel.
Japanese researchers and auto parts makers say the new wood-pulp material weighs only one-fifth that of steel and could be five times stronger than metal.

Cellulosic nanofibers are used in products ranging from inks to transparent displays, but their potential use in cars has been included in the "Kyoto Process," in which chemically treated wood fibers are kneaded into plastics. This method reduces the cost of production by about one-fifth of the cost of other processes.

It is the cheapest, high-performance cellulose nanofiber product, which is why we are focusing on it for use in automotive and aviation parts, said Kyoto University professor Hiroaki Yano.

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, ... >>

Fossil Giant Rabbit 11.06.2011

On the Mediterranean island of Menorca, Spanish paleontologists have found the bones of an extinct giant rabbit. He was six times the size of his usual counterparts and weighed 12 kilograms.

Judging by the structure of the legs and spine, a huge rodent that lived on the island three to five million years ago could not jump and moved mainly by walking. Its ears were smaller and less mobile than those of modern rabbits. Paleontologists explain all these features by the fact that there were no predators on the island that would hunt rodents.
