transparent clay

16.04.2007

Japanese scientists have created a new composite material from a hydrophobic polymer of polyethoxymethyl acrylate and hydrophilic clay of volcanic origin. Unexpectedly, the new material was elastic and transparent, and the transparency is maintained when the proportion of clay is increased to 30 weight percent.

Unlike clay, the composite does not swell upon contact with water, and unlike a polymer, it does not dissolve with organic solvents. The possibility of practical application of the new material is considered.

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 ... >>

Mini air conditioner Sony Reon Pocket 5 09.05.2024

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, ... >>

RealSense webcams 16.11.2016

Intel RealSense technology has been advertised for a long time. Among other things, it allows you to use the Windows Hello function, that is, to log into the Windows 10 environment by recognizing the user's face. With ordinary webcams that do not have an infrared module for determining the depth of space, this function does not work, which means that it is not useful for the vast majority of users, even if they would like to use this feature.

In Japan, official sales of the Intel RealSense 3D SR300 camera have begun. Outwardly, it resembles a small copy of the Xbox Kinect and is more suitable for use with desktop systems than Kinect, which is designed for the user to be at a considerable distance from the TV to which the Microsoft game console is connected. The SR300 supports 1080p video capture at 60 frames per second.

But in addition to regular video shooting, the SR300 has an additional infrared camera and an infrared laser. Their combination allows the camera to work as a 3D scanner, as well as recognize user gestures and facial expressions. The novelty is connected to the USB 3.0 port, it is also powered from it and does not require additional adapters. The field of work for this model extends from 20 to 120 centimeters from the lenses. The SR300 is mounted either on the top edge of the monitor using a classic "clothespin", or on the included small tripod tripod.

The cost of new items is $230.
