Durable aluminum based glass

16.07.2023

Scientists from the University of Pennsylvania have developed an innovative technology for the production of glass that is durable, environmentally friendly and uses less energy.

The new material, called LionGlass, is an alternative to traditional glass based on sodium, calcium and silicate. LionGlass is up to 10 times more resistant to damage while producing lower carbon footprint and lower energy consumption.

To create LionGlass, engineers replaced the soda ash in the traditional recipe with alumina or iron oxide. The content of silicon dioxide in the material can vary from 40% to 90% by weight. The manufacturing process of the composite material is carried out at a relatively low temperature of 400°C, which reduces energy consumption by 30%.

The strength of LionGlass was tested using a Vickers diamond indenter, which is used to measure the strength of materials. Studies have shown that LionGlass does not crack even under a load of 1 kg, while ordinary glass begins to crack at a load of 0,1 kg. LionGlass is speculated to be capable of withstanding even greater loads, however, due to testing equipment limitations, this has not been verified.

Increased strength opens up broad prospects. Using this material, you can create thinner and stronger objects. This reduces the consumption of electricity and raw materials, as well as reducing transportation costs.

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, ... >>

climate decoder 19.05.2020

Scientists from Cornell University have created a climate decoder - it will help search for life on exoplanets.

Exoplanets are planets outside the solar system. To date, scientists are aware of the existence of thousands of such objects, and at least part of them may have life.

Now scientists are trying to determine how the climate existing on exoplanets is suitable for life in the terrestrial sense, actually manually. This process takes a lot of time - while in the near future astronomers plan to launch a new generation of telescopes that will increase the number of exoplanets known to science by an order of magnitude.

In order to automate the determination of the climate of exoplanets, the researchers created a climate decoder. It is based on a combination of details of the color of the planet's surface and light from the host star to calculate the climate on it. For example, a rocky black basalt planet absorbs light well and will be very hot, but if you add sand or clouds to the atmosphere on its surface, it will cool down.

Depending on the type of star and the exoplanet's primary color - or reflective albedo - the planet's color can soften some of the energy released by the star. This allows us to determine whether there are clouds in the atmosphere and how its surface is arranged - and, ultimately, to determine its climate.
