Antibacterial web material

11.09.2020

The University of Bayreuth has created a material that can eliminate the risk of infection and facilitate the healing process. This is a nanostructured material based on spider silk proteins. It prevents colonization by bacteria and fungi, but at the same time actively promotes the regeneration of human tissues.

Therefore, such material is ideal for implants, dressings, prostheses, contact lenses. Biotechnologically produced spider silk proteins have made it possible to create a material that prevents the adhesion of pathogenic microbes. Even streptococci, resistant to many antibacterial agents, could not settle on the surface of the material.

Moreover, according to the developers, the material guarantees the active reproduction of human cells, which allows it to be used in wound dressings, in the process of skin grafting and any implantation. Unlike other materials that were previously used for tissue regeneration, the risk of infection is completely eliminated. And the effect is not achieved due to toxic effects on pathogens. The secret lies in the structure itself - it makes it impossible for pathogens to attach to the surface.

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, ... >>

Hearing aid with fitness tracker and foreign speech translator 02.09.2018

Starkey has introduced Livio AI, the world's first hearing aid that is equipped with a variety of sensors and an artificial intelligence system. In fact, Livio AI belongs to the category of wearable electronics.

Livio AI allows people with hearing impairments to hear everything that is happening around them much better. In addition, when there is loud background noise, the device automatically cuts off noise and focuses, for example, on the interlocutor's speech. The hearing aid allows you to select different modes of operation depending on where you are. It can be configured in a wide range using the appropriate mobile application.

Livio AI also acts as a fitness tracker, it collects information about your physical activity, and also notes how you are able to carry on a conversation without stopping moving. The device is equipped with support for the personal assistant Alexa, which will help you find the information you need or play your favorite music. In addition, the built-in artificial intelligence system allows real-time translation of speech into various languages.

Livio AI is initially planned to be released in North America, and in 2019 the device will appear in 20 countries around the world.
