For marking film capacitors, 5 colored stripes or dots are used:

The first three encode the value of the rated capacitance, the fourth - the tolerance, the fifth - the rated operating voltage.

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Artificial organic neurons 16.01.2023

Researchers at Linköping University (LiU), Sweden, have created an artificial organic neuron that closely mimics the characteristics of biological nerve cells. This artificial neuron can stimulate natural nerves, making it a promising technology for various medical procedures in the future.

At the LOE Organic Electronics Laboratory, work continues to develop increasingly functional artificial nerve cells. In 2022, a team of scientists led by assistant professor Simona Fabiano demonstrated how an artificial organic neuron can be integrated into a living carnivorous plant to control the opening and closing of its mouth. This synthetic nerve cell matched 2 of 20 characteristics that distinguish it from a biological nerve cell.

Researchers at LiU have developed a new artificial nerve cell called conduction-based organic electrochemical neuron, or c-OECN, that accurately mimics 15 of the neurons. 20 neural features that characterize biological nerve cells, making them function much like natural nerve cells.

One of the key challenges in creating artificial neurons that effectively mimic real biological neurons is the ability to turn on ion modulation. Traditional artificial neurons made of silicon can emulate many neural functions but cannot communicate via ions. In contrast, c-OECNs use ions to demonstrate several key features of real biological neurons," says Simone Fabiano, Principal Investigator of the Organic Nanoelectronics Group at LOE.

In 2018, a research group at Linköping University was one of the first to develop organic electrochemical transistors based on n-type lead polymers, which are materials that can produce negative charges. This made it possible to create complementary organic electrochemical circuits for printing. Since then, the group has been working on optimizing these transistors so they can be printed on a printing press on thin plastic foil. As a result, it is now possible to print thousands of transistors on a flexible substrate and use them to design artificial nerve cells.

In a newly developed artificial neuron, ions are used to control the flow of electron current through an n-type lead polymer, resulting in voltage spikes in the device. This process is similar to what happens in biological nerve cells. The unique material in the artificial nerve cell also allows the current to increase and decrease in a near-perfect bell curve, reminiscent of the activation and inactivation of sodium ion channels found in biology.

In experiments carried out in collaboration with the Karolinska Institute (KI), novel c-OECN neurons were connected to the vagus nerve of mice. The results show that the artificial neuron can stimulate the nerves of mice, causing a 4,5% change in heart rate.

The fact that an artificial neuron can stimulate the vagus nerve itself could pave the way for important applications in various forms of treatment in the long run. In general, organic semiconductors have the advantage of being biocompatible, soft and ductile, while the vagus nerve plays a key role in, for example, the immune system and the body's metabolism.
