Threads tracking gas

14.03.2020

Various electronic devices for determining the presence of certain harmful gases in rooms or in the atmosphere as a whole, of course, are widely used and distributed, but still have a relatively high price for manufacture and sale, which often makes them not quite suitable for their purpose. .

That is why a team of chemical engineering specialists from Tufts University in Massachusetts presented their new interesting development of special colored threads embedded in the fabric of clothing that can detect the presence of harmful and dangerous impurities in the atmosphere, demonstrating this by changing their primary color.

Such a development, as it becomes clear from the preliminary description, has a truly remarkable level of quality and a lower price compared to traditional signal electronics. The threads themselves are a combination of special fabrics and polymers treated with dyes, namely MnTPP dye, blue bromothymol and red methyl. The first two can detect the presence of ammonium gas, and the third - oxygen chloride.

They then made their surface more resistant and stronger by treating them with acetic acid, and after that they added an organic polymer called polydimethylsiloxane - or PDMS for short - which made the outer sheath of the colored threads more chemically stable while at the same time allowing it to change the color indication of the paint. depending on the presence of a particular harmful gas in the atmosphere. It should be noted that so far the development is experimental and does not claim to be widely distributed on the market and in medicine in general.

A similar fabric option that can detect traces of harmful gas impurities can be really great in the long run, serving as a chemical and engineering base for creating even more versatile and accurate designs in this segment. Thus, we have to wait for news regarding the progress in the development and modernization of such a colored fabric, which will surely surprise everyone in the future!

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, ... >>

Logitech Reach webcam on articulating arm 15.09.2023

Logitech has unveiled an innovative webcam called Reach, featuring an articulating arm that allows you to precisely adjust the camera's position and move it smoothly during video conferencing.

The manufacturer claims that Reach will significantly improve the interactivity of online meetings and will become an indispensable tool for education and streaming.

Reach will be available in two versions: a standard version for placement on a desktop and a clamp-style version that allows you to attach the camera to the edge of a table. Both versions come with a flexible tripod arm, which is similar to those used for microphones and other cameras.

This hand ensures smooth movement of the camera vertically and horizontally, and also allows you to rotate the camera itself. The main features of Reach are its smoothness and stability, which makes it unique among similar devices. Manufacturers claim that such devices typically do not allow the user to quickly and accurately adjust the desired camera position, but Reach will change this practice.

The Reach webcam itself is a Logitech StreamCam model released in 2020, capable of recording 1080p video at 60 frames per second. It is equipped with autofocus and supports 4,3x zoom. If the camera fails, you can replace it with a new StreamCam rather than purchasing a complete kit with bracket.

Logitech Reach will initially be available on the Indiegogo Enterprise crowdfunding platform. According to The Verge, the company has not yet decided on the design-to-price ratio, which could range from $299 to $399 (excluding discounts for crowdfunding participants).
