oily water

15.07.2004

The English company "Aqualider" has developed a new composition for extinguishing fires. This is "Fok-Stop" - a granular, highly hygroscopic polymer, like the one used in diapers.

When 0,1-0,2% polymer is added to water, a transparent, rather viscous mass is formed that can be pumped through a fire hose. Firefighters nicknamed this mass "greasy water." Unlike rapidly flowing water, it sticks to vertical burning surfaces and remains in place for a relatively long time, smothering the fire.

"Fok-Stop" is not dangerous for living organisms, does not pollute the environment (similar polymers are used in agriculture to retain moisture in the soil). The new composition is especially effective in forest fires, protecting tree trunks.

In England it is already used by 55 fire brigades. Interest was shown by Australia, Hong Kong; 15 European and 21 Latin American countries.

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 ... >>

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, ... >>

Free encrypted iPhone calls 17.08.2014

An analogue of the RedPhone application for Android has become available to iPhone owners. It allows you to talk with other subscribers over an encrypted communication channel. Connection is possible not only between iPhone, but also between iPhone and Android. In the near future, the authors promise to add support for encrypted text messages to the program.

In order to make encrypted calls, it is necessary that the second subscriber also has the Signal application or a compatible RedPhone equivalent, which was previously released for the Android platform.

Thus, secure voice communication is possible both between iPhone owners who have installed Signal, and between an iPhone owner and an Android owner, provided that the latter has the RedPhone application. Android device owners can also communicate with each other.

Calls are made using a data network or Wi-Fi connection. The applications themselves are free, the user only needs to pay for traffic.

Signal and RedPhone are based on ZRTP, an open source technology co-authored by Philip Zimmermann, creator of the popular PGP email encryption technology.
