Dry impregnation of fabrics

17.11.2005

The French company "Fibrolin" has developed a method for impregnating fabrics and non-woven materials with water-repellent, fire-fighting and other agents, which does not require either water or other solvents.

According to the principle of operation, the process resembles photocopying and was invented by a Belgian engineer who previously worked at Xerox. The powder of the substance with which the textile is to be impregnated is introduced into the fabric by a high-voltage electrostatic field. The penetration depth, for example, in felt is up to three centimeters.

After embedding, the fabric is subjected to heat to melt the powder and bind to the fibers. The process is used in the manufacture of fabric upholstery for car interiors, car seat covers and other textile products.

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, ... >>

Meat steak grown from tenderloin 20.03.2023

Swiss startup Mirai Foods has unveiled the world's first cage-grown steak. The startup has been working on the creation of cultured meat for a long time. Now the company claims that they have managed to make the first real breakthrough. The technology has already received three patents and the name Fibration Technology. Mirai Food said the discovery is due to a naturally renewable cellular process that allows tissue to be grown to mimic conventional meat.

"The fillet steak is the most difficult challenge: it consists of different types of cells, which, when combined correctly, lead to a complex structure of meat," says the founder of the startup.

The steak was made in a bioreactor of our own design.

Steak meat is made from long cultured muscle fibers, which are then combined with enzymes and supplemented with cultured adipose tissue. The process of creating meat in this way takes five days, after which "the central part of the tenderloin comes out, from which steaks of almost any thickness can be cut."

"We can offer a real alternative to regular meat, using our technology, you can cook and eat a real steak - and know that no animal has died for it and the climate has not been harmed. Nutrition is a huge lever to improve the level of animal climate protection: expected that the demand for meat will double by 2050. At the same time, traditional methods of meat production can no longer satisfy this demand," the CEO of the startup said.

The company is set to lead the culture-based whole meat industry, in which most products are still more like ground meat for burgers and nuggets. At the same time, since the beginning of this year, the British company BSF Enterprises has introduced a whole pork tenderloin, and Japanese industry experts claim that they have also developed a whole steak from cultured cells.

But according to the Swiss startup, they are capable of producing cultured meat without the use of genetic engineering. The use of GMOs is very limited in the EU, which is why the company claims to focus on the benefits of European consumers.
