Found a way to increase the efficiency of solar power plants

11.07.2022

Scientists from Stanford University in the USA have developed a cheap lens for solar panels that can collect up to 90% of the light and increase its brightness by 3 times. Passive Axially Graded Index Lenses (AGILE) photocell technology can help reduce the footprint of solar power plants.

Solar energy will play an important role in meeting sustainable future energy needs. The technology could help install solar panels in small areas where it was not possible before.

AGILE does not require solar tracking and respects the maximum limit of the cosine projection by concentrating light falling on it from all angles.

With AGILE, pointless concentration systems (i.e. without having to follow the Sun) can be used, which reduces the amount of photovoltaic material and also effectively absorbs stray light. After all, the scattering of light due to cloud cover and the atmosphere can reach 20% even on a sunny day.

The AGILE concept The AGILE concentrator matrix system consists of a repeating block that absorbs all incident light and therefore appears dark. This graded index immersion optics can also be applied in areas such as light control in solid state lighting, laser connectors, display technology, etc.

The scientists used strong, broadband transparent and inexpensive sorted materials for two AGILE prototypes: a glass pyramid made by stacking different glass plates and an overlapping polymer array of cones.

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, ... >>

Why can't you eat if you eat a lot 27.06.2016

American scientists have explained why an excessive amount of food causes overeating. Excess calories block the production of a hormone that helps us feel full.

A recent study points to a previously unknown role for the hormone uroguaniline in the development of obesity. Once in the brain, uroguaniline contributes to the formation of a feeling of satiety. However, if too much food enters the intestines, the production of uroguaniline stops, and the overeating person does not feel full.

A research team led by Scott Waldman of Thomas Jefferson University conducted experiments on mice. In the intestines of overfed animals, the production of the hormone stopped, but resumed when the diet was observed.

Interestingly, this effect occurs only when overeating and is independent of fitness: Uroguaniline production is stopped in the same way in normal and obese mice. Only a one-time excess of calories is important.

Scientists were able to experimentally prove that the effect on the endoplasmic reticulum, the cell organelle that is responsible for its production, leads to the cessation of hormone production.

“Now it is clear that extra calories from fat or carbohydrates act as a stress factor for the cells of the small intestine. In response, they stop producing uroguaniline, which helps people feel full after eating. We just don’t know how much “too many” calories is, and which molecular sensor makes the decision," the researchers say.
