Scientists have developed a system to warn of emissions of deadly gases that could help save the lives of soldiers in wars, in addition to mining and sewer lines.
Factories and boilers also occasionally emit many gases, including carbon monoxide and ammonia. A manual sensor can now be worn on the body as a wearable developed by the Pohang University of Science and Technology (POSTEC) in South Korea.
In many countries, including Pakistan, miners die of suffocation due to gas from mines or manholes. In this regard, PostSec Professor Jensk Rowe and his colleagues have developed a hand-held hologram sensor that provides an immediate warning of dangerous gases.
They have developed a gas reactive liquid crystal optical modulator that instantly appears in the form of a hologram that can also be considered an alarm. Details of this invention were published in the Journal of Science Advances on April 7, 2021. This sensor will help save lives in oil wells, gas plants and other such dangerous places.
Although commercial gas sensors are available but cannot be carried, they are difficult to use and show results very late. Now the solution to this problem is to use ‘Metasurface’ which is used to make objects disappear in visual deceptions. The refractive index of light is controlled in such a way that a two-way hologram or 3D video or image is obtained.
Similarly, a hologram on the metasurface of a manual device shows the presence of gas. As the toxic gas hits the sensor, a hologram is formed to change the configuration of the liquid crystal molecule. It was first tested on isopropyl alcohol, a dangerous gas that causes stomach and headaches, drowsiness, and even leukemia. The sensor identified it within a minute, even if it was 200 parts per million, and the report appeared on a hologram.
This whole system is built on nano-compositing with a flexible layer. Experts believe that this will be an effective tool in identifying toxic gases.
Very nice post and right to the point. I am not sure if this
is really the best place to ask but do you folks have
any thoughts on where to employ some professional writers?
Thanks 🙂 Najlepsze escape roomy
I was looking through some of your content on this internet
site and I conceive this site is very informative! Retain posting.?
Your article helped me a lot, is there any more related content? Thanks!
I don’t think the title of your article matches the content lol. Just kidding, mainly because I had some doubts after reading the article.
