Intravascular surgery

01.01.2008

Canadian physicists may become the founders of a new branch of surgery - intravascular operations using magnetic resonance imaging.

A pig was injected with a syringe with a piece of steel wire one and a half millimeters long, and with the help of tomography magnets, this wire was passed through the blood vessels of the animal. The speed at times reached 11 centimeters per second.

Every 20 milliseconds, the tomograph switched from wire guidance mode to observation mode and back, so that the operator could simultaneously see and control its position.

It is assumed that this method will further destroy blood clots in the vessels.

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, ... >>

Traco TEC 2(WI) and TEC 3(WI) DC/DC Converters 28.11.2021

Traco has updated its line of 2W and 3W regulated DC/DC converters with the new TEC_2, TEC_2WI, TEC_3 and TEC_3WI families with 2:1 and 4:1 input widths (for models suffix "WI").

New generation converters have improved circuitry and modern components. The production is fully automated, thanks to which it was possible to increase the efficiency of products and reduce costs without compromising quality and reliability. The transducers are manufactured in a standard SIP-8 housing, have 1600 V DC input-output isolation, in accordance with EN 62368-1. These DC/DC converters do not require a minimum load as they operate over the full 0...100% load range.

The range of converters includes models with an extended input voltage range in the range of low values - 4,5 ... 13,2 V and 4,5 ... 18 V (for models with the ending "WI"). The permissible operating temperature range is -40...90/95°C. The converters have output protection against short circuit and it is possible to remotely turn on/off (CTRL output). These families are intended for a wide range of applications in industrial devices, instrumentation, telecommunication systems and other applications where high reliability and long life cycle are required, combined with optimal component cost.
