Lego - the perfect heat insulator

21.12.2019

Researchers at Lancaster University concluded that Lego bricks and similar parts made of ABS plastic (acronitrile butadiene styrene) and air-filled cavities are a strong thermal insulator at cryogenic temperatures.

The scientists were convinced that the structures created from the popular constructor provide better thermal insulation than the known materials for bulk insulators, and at the same time are significantly cheaper than the materials currently used - Macor glass or Vespel plastic. Experiments have confirmed that thermal insulation is provided by the very structure of the cubes and the minimum contact area between separate elements.

The authors of the paper emphasized that they do not expect a big difference in the performance of parts made of ABS and other types of plastics. The results of the study can be used in various fields, and in particular in the creation of quantum computers and reducing their cost.

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, ... >>

KODAK Launches WIFI-Connected Digital Camera 27.11.2005

Kodak has announced the launch of the EasyShare One digital camera, which the company claims is the world's first camera to feature WiFi connectivity and hence radio access to the Internet. So the owner of this camera will be able to exchange the photos taken by e-mail, while being within the range of some hotspot.

It is also reported that users of the EasyShare One camera will receive a subscription to a trial version of the service of T-Mobile, which is a network provider of 12 hotspots located around the world, when purchasing this camera.

The technical characteristics of the EasyShare One camera are as follows: 4-megapixel matrix; 256x optical zoom; 3 MB internal memory; 640-inch swivel touch screen (electronic pen supported); support for recording videos with VGA (480x30) resolution at XNUMX frames per second; slot for SD/MMC expansion cards; the already mentioned WiFi communication module in the form of an expansion card.

Note that the WiFi module included in the kit only supports 802.11b radio networks, and to organize communication over a faster 802.11g network, you will have to buy another expansion card. The price of the EasyShare One camera together with the WiFi card is 599USD.
