Direct lithography of optical systems based on perovskite

16.02.2022

Direct lithography of perovskite nanocrystals inside glass with the ability to adjust the composition was implemented by a group of researchers from China.

Perovskites are a type of mineral that has special optical properties. Because of this, it is well suited for the creation of fuel cells and electronic devices such as cathodes and LEDs. But as the researchers note, the processing of minerals usually involves the use of special solutions, which leads to low structural stability.

The researchers developed a new approach - using ultrafast laser pulses to perform 3D direct lithography of perovskite NCs with the ability to tune the composition. The impact of the laser also increases the pressure, resulting in the separation of the liquid nanophase.

The scientists carried out their experiments on oxide glasses made of lead, cesium and halide. They then used a laser to engrave 3D patterns into the glass mass.

They managed to carry out etching of pixel dots with different wavelengths of radiation. Thus, the possibility of using the technology for the manufacture of micrometer-sized LEDs was demonstrated. XNUMXD color images of letters, numbers and symbols were then etched. As well as multi-colored arrays to show the possibility of using this technique to create glass-based memory devices.

This process can be used to create materials that work in a variety of optical applications. They also note that the products produced are much more stable than those used in solution etching, even under conditions of changing temperature or other environmental parameters.

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, ... >>

Mean Well HRP/N power supplies 14.02.2021

Mean Well has developed a family of power supplies capable of short-term safe operation at up to 2,5 times the rated power (up to 5 seconds).

The new family consists of three series: HRP-150N, HRP-300N and HRP-600N with power ratings of 150W, 300W and 600W, respectively. In addition, the power supplies have excellent functional saturation: they have a power correction stage (PFC; PFC> 0,95), the ability to compensate for voltage drops on the wires, the ability to remotely turn on / off, and are resistant to input voltage increased up to 300 V (up to 5 seconds) and have a "DC Ok" signal to control the output voltage. With all this, these power supplies are operable in the temperature range of -40 ... 70 ° C and have an efficiency of 89%.

This family of power supplies is in demand in industrial installations using electric motors or with capacitive loads. At the moment of starting, the specified load consumes increased power, therefore, in order to ensure a normal start, a more powerful power source must be selected. In further work after the launch, the power of this source is no longer used and is redundant. Therefore, by using the new HRP/N power supplies, you can get rid of redundancy and gain economic benefits.

The warranty period for the considered power supplies is 5 years.
