Cotton conductor

22.04.2010

The idea of embedding electronics in clothes has been haunting designers and journalists for a long time. However, engineers are not yet ready to implement it in the required format - that is, so that a T-shirt-player, jacket-flashlight or hat-telephone would be comfortable and safe. One of the problems - obtaining a fabric capable of conducting electricity - is close to being solved.

At a fashion show held at Cornell University (USA), Associate Professor of Fiber Optics Juan Inestrosa and his Italian colleagues from the Universities of Bologna and Cagliari demonstrated a conductive cotton fabric.

Unlike analogues, it is as soft and light as ordinary fabric, and does not lose its conductive properties either when washing, or when ironing, or when repeatedly creasing. To achieve success, scientists have developed a technology for applying a layer of semiconductor polymer with metal nanoparticles to cotton fiber.

Abbi Leibman, a graduate student from the Design Department, was able to add a few knots to construct a dress from this fabric that can generate electricity using flexible solar panels and recharge it with an MP3 player or phone. The USB port required for this is hidden in the belt.

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, ... >>

artificial uterus 18.12.2022

Yemeni molecular biotechnologist Hashem Al-Ghaili claimed to have developed the world's first concept for an incubator to raise children. The EctoLife installation, according to preliminary estimates, will be able to "carry" up to 30 thousand children a year, and future parents will be able to monitor the process using mobile applications.

Al Ghaili said EctoLife could one day replace traditional births: "Society can finally meet the needs of parents who are tired of waiting for a response from an adoption agency and concerned about pregnancy complications." The scientist also said that this artificial uterus will help to withstand the crisis of infertility.

The EctoLife artificial womb concept is to help babies develop at full term "without biological interference".
