Comments on the article
In accordance with GOST 11076-69 and the requirements of IEC Publications 62 and 115-2 (IEC), the first 3 or 4 characters carry information about the value of the resistor, determined by the base value from the E3 ... E192 series, and the multiplier. The last character carries information about the tolerance, i.e. resistor accuracy class. The requirements of GOST and IEC practically coincide with another standard BS1852 (British Standard).
In addition to the line that defines the value and tolerance of the resistor, additional encoded information about the type of resistor, its rated power and release date can be applied.

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 ... >>
| Random news from the Archive Electrically conductive biogel for inkjet printer
16.07.2012
Researchers from Stanford University reported in the latest issue of Proceedings of the National Academy of Sciences that they have created an electrically conductive gel that can be applied to surfaces using an inkjet printer. According to scientists, it is a hydrogel that looks and behaves like biological tissue, but is able to conduct electricity like a metal or semiconductor.
Associate professors Zhe Nan Bao and Yi Kui, who lead the development, created their gel by linking long polymer chains of aniline with phytic acid, which is part of plant tissue. Its molecules are able to bind to six polymer chains at once, creating a complex three-dimensional web from them.
Commercially available conductive polymers are homogeneous films devoid of any nanostructure, while the material created by the Stanford group is like a sponge filled with many nanopores. This nanostructure, which greatly increases the total surface area of the gel, increases the amount of electrical charge it can hold, enhances its ability to "feel" chemical compounds, and dramatically speeds up its electrical response to an external field.
The simplicity and low cost of preparation, as well as the ability to apply it to surfaces with an inkjet printer, make this gel commercially available now and very attractive to manufacturers who want to create electrodes of complex designs at a cheap price.
Most hydrogels are not electrically conductive, however, phytic acid not only binds polymer chains, but also endows them with a charge, imparting high electrical conductivity, the ability to hold a very high charge, etc. The fact that this material is similar to biological tissue may allow biological systems to communicate through him with various technological equipment. The range of its possible applications, scientists say, is unusually wide - from medical probes and laboratory biosensors to biological fuel cells and super-powerful energy storages of the future.
