1 Gbps over infrared

07.10.2012

The infrared communication technology, which was quite widespread in mobile devices in the PDA era, over time gave way to radio frequency technologies, which surpassed it in data transfer speed and were not so demanding on the relative position of devices. Meanwhile, the veteran still has potential, experts from the Dresden Institute for Photonic Microsystems (IPMS) from the Fraunhofer community believe, who have managed to create a high-speed infrared transceiver.

According to the developers, in terms of data transfer speed, their offspring is 46 times faster than 'normal Wi-Fi', 1430 times faster than Bluetooth and six times faster than USB 2.0. In the future, the researchers expect to further increase the speed. The transceiver, which includes a laser diode and a photodetector, according to them, is the size of a "child's fingernail."

An example of the scope of the new interface is the transfer of footage from the camera to the PC. Given that manufacturers may be interested only in standardized technology, IPMS specialists participate in the 10 Giga-IR working group formed by the Infrared Data Association.

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, ... >>

Liquid nanotransistors for supercomputers 29.03.2013

The advantage of liquid nanotransistors is that they remain 'on' or 'off' in the absence of drive current. In the future, based on them, it is possible to create powerful and efficient computing devices. Scientists at the IBM Almaden Research Lab in San Jose, Calif., have unveiled a new experimental way to store information in liquid nanotransistors, Technology Review reports.

The researchers demonstrated a material consisting of nanochannels filled with an electrolyte. If an electric current is applied to such a material, a layer of ions is formed in it, which changes the conductivity properties of the materials. This process is reversible. By applying electricity to a given material, it can be switched from a state of conduction to a state of non-conductivity and vice versa, thus writing a one or a zero.

A feature of liquid nanotransistors is that they do not need a constant supply of electricity in order to maintain their current state, explained Stuart Parkin, IBM Research Fellow, one of the project participants, who is involved in another IBM project - development ' memory with a treadmill'.

"Unlike today's transistors, the new material can be switched 'on' or 'off' permanently without the need to maintain the state," he said, adding that over time this property could lead to new, more efficient logic devices and computer memory. The liquid nanotransistors created by scientists make it possible to build electronic circuits that can be reprogrammed. This opens up more opportunities than today's processors, where the configuration of the electrical channels cannot be changed, Parkin said.

The problem is that the transition of liquid nanotransistors from one state to another is slow - one or two orders of magnitude slower compared to the speed of modern microcircuits. Reducing the size of the transistors and placing them closer together could solve the problem, Parkin said. Ultimately, with their help it will be possible to create powerful computing devices with lower energy consumption, the scientist believes. According to Parkin's colleagues, the new technology has yet to be studied well enough to see if it can contribute to the development of the microelectronics industry.
