Single EU Cell Phone Charger

20.03.2014

All cell phones sold within the European Union will be required to use a single standard charger. 550 out of 570 members of the European Parliament voted for such a requirement. In the next two years, this rule should be introduced into the legislation of all EU countries, and manufacturers will have another year to bring their products into line with the law.

According to parliamentarians, the transition to a common standard will help reduce "electronic waste", costs and inconvenience to consumers.

Note that in fact we are talking about the transition to the micro-USB connector, which is already used by most manufacturers, so the de facto requirement for standard charging was fulfilled at the stage when it was advisory in nature. Manufacturers who are out of step so far will have to take action if they want their products to remain on the European market beyond 2017.

The directive also streamlines the placing on the market of radio equipment, including cellular phones and modems. The need for this is due to the explosive growth in the number of products that can potentially affect the health of consumers and the work of each other.

Using information provided by EU members, the European Commission will determine the categories of equipment that will require mandatory registration in order to enter the market. A similar mechanism is already in operation in the US.

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, ... >>

Thubber: super elastic rubber with metal properties 18.02.2017

Scientists at Carnegie Mellon University have developed a thermally conductive rubber material that could be a breakthrough in the development of soft stretchable mechanisms and electronics.

The new material, dubbed "thubber", is an electrically insulating material with the thermal conductivity of metals, the elasticity of soft, biological tissues, and can stretch to six times its original length.

"Our combination of high thermal conductivity and elasticity is particularly important for the rapid dissipation of heat in devices such as body-worn electronics or soft robots that require mechanical flexibility and stretchable functionality," the researchers say. Such materials can also be used in sportswear and medicine, energy and transportation.

The key ingredient of the new rubber is a suspension of non-toxic liquid metal microdroplets. The liquid state allows the metal to deform along with the surrounding rubber at room temperature. When the rubber is stretched, the droplets form elongated trajectories that are effective in dissipating heat. Despite the large amount of metal, the material also retains electrical insulating properties.

To demonstrate the properties of the material, the scientists attached LEDs to a strip of thubber to make a lamp that any runner can wear around their leg. The new material dissipates the heat from the diodes, which would otherwise burn a person. The researchers also created a soft robotic fish that swims with the help of a thubber tail without the help of conventional motors or gears.
