Dry cleaning can be dangerous

03.12.2011

Fifteen-year-old schoolgirl Alexa Danzler from the city of Arlington (USA) became interested in the problem: do the dangerous chemicals used in this process remain on clothes after dry cleaning?

She sewed squares of wool, silk, cotton, and polyester into the lining of seven identical men's jackets and took the jackets to the dry cleaners. Some jackets have been dry-cleaned up to six times. Then the schoolgirl turned to the local university with a request to do a chemical analysis of the experimental shreds.

It turned out that they still contained the solvent perchlorethylene, which is used in most dry cleaners and is known to cause cancer and neurological diseases. Moreover, this chemical is the greater, the more often the fabric was cleaned, and especially it accumulates in wool.

Although all countries have standards for the permissible levels of perchlorethylene vapor in industrial premises, no one has yet thought about its residues in clothing.

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 ... >>

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, ... >>

Antistress for drivers 14.07.2019

The British company Jaguar Land Rover is developing a new technology based on artificial intelligence that will target the driver's mood and try to improve it.

The system will use data from the cabin camera and biometric sensors to analyze and evaluate the driver's condition, adapting a number of functions, such as heating, ventilation and air conditioning systems, as well as multimedia system and lighting settings. Different settings will change depending on the expression on the driver's face to help him relieve stress and calm down as soon as possible.

The new system will work on the basis of advanced artificial intelligence technologies, which will allow you to instantly adapt to subtle changes in the facial expressions of each individual person and automatically activate the appropriate settings. Over time, the system will learn the driver's preferences and be able to select the appropriate settings with maximum accuracy: changing the contour lighting, adjusting the temperature and selecting music tracks.

Jaguar Land Rover is also testing a similar technology for rear passengers, which will work based on cameras in the front headrests. If the system detects signs of fatigue, it can dim lights, darken windows and raise the temperature in the rear of the car to help passengers sleep. The system software represents a new generation of driver fatigue control technology.
