External optical drives Buffalo BRXL-PC6VU2-C

30.08.2013

Typical Buffalo introduced external optical drives designed for connection to the USB port, which is used not only for data exchange, but also for powering the device. If the power provided by the port is not sufficient to operate at maximum speeds (increasing power consumption), the drive signals this with an LED indicator.

To increase the speed, you can use the power adapter included in the kit. Such a solution can be appreciated by users of mobile computers who take the drive with them on a trip. Being willing to sacrifice the speed of the drive, they may not need to carry a power adapter with them. In addition, the ability to work "at half strength" is useful when connected through a hub.

The BRXL-PC6VU2-C series includes drives measuring 145 x 153 x 19 mm and weighing approximately 340 g in several colors. They support reading and writing Blu-ray XL media. Four-layer and three-layer discs are recorded at 4X speed, dual-layer and single-layer Blu-ray discs at 6X speed. When powered by USB, the write speed of all Blu-ray discs is limited to 2X. DVDs are recorded at 8X, CDs at 24X.

The price of new items in Japan, where sales will start in September, is $112.

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, ... >>

Getting water even from desert air 09.09.2019

Despite the fact that advanced technologies serve humanity in the XNUMXst century, many populated regions on our planet still suffer from a shortage of drinking water. But this crisis can be resolved in the near future. Yagi, a chemist at the University of California at Berkeley, said he and his colleagues have created a solar-powered device that could provide water to millions of people.

It is based on a porous crystalline material known as a metal-organic framework (MOF) that acts like a sponge: it sucks water vapor out of the air, even in the desert, and then releases it as liquid water.

Yagi and his colleagues synthesized the first MOF in 1995, and since then chemists have designed tens of thousands of similar structures. Each is made up of metal atoms that act as hubs connected in a porous network by organic linkers designed to quickly hold the hubs and create openings to accommodate molecular "guests". By mixing and matching metals and linkers, the researchers found they could tailor pores to trap gas molecules such as water vapor and carbon dioxide (CO2).

The first versions of the device using MOF turned out to be too expensive - chemists used zirconium, which costs about $ 160 per kilo and therefore is not profitable for the mass industry. However, they recently solved this problem: the new frame was already synthesized on the basis of aluminum (which costs $3 per kilogram) and was named MOF-303.

The initial efficiency also left much to be desired. But now, using MOF-303's ability to fill and empty pores in just minutes, the team can do dozens of these cycles every day. Backed by a solar panel to power a fan and heater that speed up cycles, the device produces up to 1,3 liters of water per kilogram of MOF per day, even from desert air. But this is not the limit: Yagi expects further improvements that will increase this amount to 8-10 liters per day. Last year, he founded Water Harvesting, which plans to release a microwave device this fall that can produce up to 8 liters a day. Next year, the company is promising a large-scale version that will produce 22 liters per day, enough to supply a small village. "We're just making water mobile," says Yagi. "It's like taking a wired phone and making it wireless."
