Photosynthesis will help improve solar panels

03.09.2017

Georgia State University researchers are using photosynthesis to improve the efficiency of solar panels.

During photosynthesis, plants and other organisms, such as algae and cyanobacteria, convert solar energy into chemical energy, which is then used as fuel for further life.

As noted, in plants, the light energy of the sun causes the electron to quickly move across the cell membrane, and it never returns to its starting point. In artificial solar cells, electrons often return, losing energy. That is why the absorption of solar energy in plants is so efficient.

According to scientists, a close study of the processes that occur during photosynthesis will allow more efficient design of solar panels.

Plants convert solar energy ultra-efficiently, far more efficiently than any artificial solar cell. During photosynthesis, light passes through the electron membrane and does not return. The big problem with artificial systems is that the electron keeps coming back. It's a real mystery why plants are so efficient at converting solar energy.

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, ... >>

Insulation of houses with cigarette butts 22.11.2020

Australian scientists have proposed using crushed cigarette butts to keep the house warm. They plan to add them to the clay from which bricks are made.

Just one percent of cigarette butts in clay can reduce the energy required to fire bricks by 20 billion megajoules. Such bricks will become lighter in weight, and their thermal conductivity will be lower.

So that cigarette butts do not leave an unpleasant odor and harmful bacteria, they will be treated with ozone and ultraviolet light. Such technology, among other things, will help get rid of thousands of tons of decaying waste.
