Turbine blades protected

12.03.2012

Fast mountain rivers often carry a lot of sand and small pebbles, which soon abrade the blades of turbines installed on such rivers to generate electricity.

At one of the mountainous hydroelectric power plants in Peru, a special turbine for muddy rivers, created in Norway, was successfully tested. The surface of the metal is covered with tungsten carbide, which is well resistant to the abrasive action of sand.

Serial production of new turbines is being established.

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, ... >>

NXP technology helps save up to 80% on electricity 30.11.2008

NXP Semiconductors has taken the next step in its energy saving journey with the announcement of the delivery of its 250 millionth fluorescent lamp chip.

Fluorescent lamps are highly efficient, energy-saving lighting solutions that save up to 80% energy compared to conventional incandescent lamps. By developing these fluorescent lamps, NXP has helped reduce carbon dioxide emissions by 500 million kg per year compared to more traditional lighting solutions.

NXP supports the energy saving trends in the lighting industry. For example, daylight maximization technology changes light levels based on natural light levels.

NXP supplies lighting control ICs for a range of technologies used every day in shop and office lighting, such as HF TL (High Frequency Tube Lamp), CFL, HID (High Intensity Discharge Lighting) and Solid State Lighting (SSL) technologies, to name a few. NXP also supplies a wide range of driver ICs for a new lighting technology called Solid State Lighting, which is based on high brightness LEDs.

Solid State Lighting technology has a broad future, providing a high degree of reliability, design flexibility and long device life. Potential applications of the technology include, among other things, outdoor lighting systems - the use of SSL technology in them will allow to regulate the illumination of city streets and highways. In addition, LED systems with NXP lighting control chips allow you to control the intensity of lighting.
