Hybrid OLED with 111,7 lm/W

08.11.2013

Specialists from the Chinese company First-O-Lite have succeeded in developing a highly efficient light source that uses a hybrid organic light emitting diode. The luminous efficiency of a device with an area of 2 cm2 reaches 111,7 lm/W at a brightness of 1000 cd/m2. To obtain white color, a combination of one fluorescent and two phosphorescent emitters is used. According to the company, it may be the most efficient hybrid OLED to meet Energy Star's emission spectrum requirements.

First-O-Lite has a manufacturing facility that is set to begin mass production of OLED panels soon. Serial panels will be characterized by a light output of 55 lm/W (at 3000 cd/m2). They use proprietary light extraction technology.

The most efficient OLED lighting fixture is considered to be the 2x2mm panel introduced by NEC Lighting in March this year. Its light output is 156 lm / W at a brightness of 1000 cd / m2.

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, ... >>

radio controlled genes 31.05.2017

It is known that many animals, such as birds, bees, lobsters, newts and others, can sense the relatively weak magnetic field of the Earth and navigate in space with its help. Such abilities are “hardwired” into the genetic code of these animals, and recently researchers from Baltimore managed to find the corresponding sequence in the genome of one fish, the glass catfish (glass catfish, Kryptopterus bicirrhis), isolate it and introduce this sequence into the genome of nerve cells in the brain of an experimental rodent. After such a genetic modification, the rodent's brain became sensitive to electromagnetic waves, and a similar technology can be used in the future for non-destructive monitoring of the activity of nerve cells and heart tissue cells, for example.

Scientists have previously been able to identify the genes responsible for "magnetic perception" in pigeons and some types of bacteria. Most of these genes are part of very complex biological mechanisms, and the gene removed from the glass catfish is unique in that it works completely on its own and is not associated with any other complex biochemical complexes.

The scientists searched for the magnetic gene by inserting segments of the catfish genome into the genome of frog egg cells. Observations of the reaction of modified eggs to a magnetic field allowed scientists to identify a gene called the electromagnetic perceptive gene (EPG). How exactly proteins produced by the EPG gene sense magnetic fields is still a mystery to scientists, which they will have to unravel in the near future. But the effect of these proteins has been known for a long time, this protein fills the cell with calcium ions, which leads to the "activation" of a neuron or contraction of a muscle tissue cell, for example.

The researchers believe their discovery opens the door to wireless biological pacemakers and brain-computer interfaces that use radio signals to communicate with nerve cells. In addition, the introduction of the EPG gene can be what gives animals and even humans another kind of sense - a sense of magnetic and electromagnetic perception, similar to that possessed by numerous superheroes from various science fiction films and works.
