Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

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, ... >>

Bacteria that eats plastic 19.03.2016

Japanese scientists have made a discovery proving that nature is learning to resist the harm that humans do to it. The answer to plastic waste pollution has been the emergence of bacteria that feed on them.

A new species of gram-negative bacteria, called Ideonella sakaiensis 201-F6, was discovered during the study of microorganisms living in the ocean. Among many different species, scientists have found a colony of bacteria that use polyethylene terephthalate (PET) in carbon and energy exchanges. This artificial substance is mainly used for the manufacture of plastic containers.

It turned out that Ideonella sakaiensis 201-F6 secrete two enzymes that decompose PET to terephthalic acid and ethylene glycol, and they are environmentally friendly. Similar properties were also previously discovered in a small group of fungi and zooplankton, but science is not yet able to adapt for large-scale processing of industrial waste.

The appearance of Ideonella sakaiensis 201-F6 is directly related to the increase in the volume of plastic on the planet: enzymes that decompose PET are a relatively new genetic modification of bacteria of the genus Ideonella. This, in turn, shows how nature begins to rebuff the aggressive intrusion of man.

In addition, Ideonella sakaiensis 201-F6 can be easily used in the field of industrial waste processing: they are not only "gluttonous", but also perfectly adapt to any environmental conditions, that is, it is enough just to place a colony of these bacteria in places where products from polyethylene terephthalate - and over time it will be decomposed into environmentally friendly components.
