Invented a way to prevent fogging glasses

16.12.2022

Scientists from the Swiss Higher School in Zurich used nanotechnology to stop the process of liquid condensation on glass.

The innovative technology consists in creating a special film consisting of two layers of gold and a layer of titanium oxide between them.

A thin (about 10 nm) coating on the glass provides a temperature increase of up to +8 °C. This helps prevent the condensation process from starting. Heating is carried out both at the expense of gold and titanium, but the latter also gives the structure additional strength.

The photo-induced heating effect provides consistent and superior anti-fogging compared to uncoated samples, as well as impressive overall indoor and outdoor performance even in cloudy conditions. The extreme thinness of the coating, obtained using standard, easily scalable manufacturing processes, allows it to be integrated with other coatings, making it durable even on highly compliant substrates.

The authors of the technology promise that the film will not heat up in the summer. They also believe that the application of this film will not affect the cost of the product. Despite the fact that gold is an expensive metal, very little is needed to cover it. In fact, the nanofilm will have a thickness 12 times less than the thickness of gold leaf.

In the future, it is planned to apply an innovative coating on the glass of glasses, as well as on mirrors and car windows. The authors also intend to conduct tests with other metals.

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, ... >>

On the Benefits of Prayer 18.04.2002

A study conducted by doctors in the United Arab Emirates found that Muslims have healthier knee joints than infidels. And if the knee of a Muslim still gets sick, it is easier to cure it.

This is explained by daily training: adherents of Islam are required to pray five times a day, kneeling for a long time (according to legend, Allah required even fifty prayers a day, but Mohammed managed to bargain for a tenfold reduction).

Arab doctors do not insist on a total conversion to Islam, but recommend appropriate gymnastics.
