5.TriboE Mask

Why in News?
  • A team of researchers at the Centre for Nano and Soft Matter Sciences (CeNS), Bangalore, have come up with a recipe for making face masks, termed as TriboE Mask, that can hold electric charges to restrict the entry of infections.
Highlights:
  • The recent innovation is based on electrostatics.
  • It uses principles of Triboelectricity.
  • When two non-conducting layers are rubbed against each other, the layers develop positive and negative charges instantly and continue to hold the charges for some time.
  • This Electric Field which is quite strong at proximity can be used to deactivate or possibly even kill the germs.
TriboE Mask:
  • The mask is three-layered –a layer of nylon cloth sandwiched between polypropylene layers.
  • Polypropylene layers are sourced from commonly used non woven grocery bags.
  • In place of nylon, silk fabric from an old saree or shawl may also be cut and used. When layers are rubbed against each other, the outer layers develop negative charges, while nylon will hold the positive charges.
  • This will act as double electric wall protection against the infectious entities crossing.
  • As the mask is made out of commonly available fabrics, it can be washed just like any other cloth and can be reused.
  • At this stage, the mask is, however, not recommended to healthcare professionals and patients.

6.Six-Planet System Discovered

Why in News?
  • Researchers have discovered a star system with six planets whose orbits are in almost perfect rhythm.
Highlights:
  • The star, dubbed HD 158259, is orbited by a “super-Earth” and “five mini-Neptunes”. Astronomers only know of around dozen star systems containing six or more planets. However, what makes the HD 158259 system so remarkable is the exceptionally regular spacing of its planets.
  • Using measurements taken using the SOPHIE spectrograph and the TESSexoplanet-hunting Space Telescope, an international team of researchers were able to precisely calculate the orbits of each planet.
  • All pairs of subsequent planets in the system are said to be close to the “3:2 resonance.”
  • This essentially means that as the first planet, or the one closest to the star, completes three orbits; the second one completes roughly two orbits. And as the second planet completes three orbits, the third completes roughly two.
  • This pattern continues for all the subsequent planets. These intriguing orbital periods could provide scientists with clues as to how the system formed, suggesting that they did not form close to their current positions.
  • The evidence indicates that the star system is compact, highlighted by the fact that the distance between the outermost planet and HD 158259 is 2.6 times smaller than the distance between the sun and Mercury in our own solar system.
  • The planets of the system, which is located around 88 light-years away, appear to have masses between two and six times that of the Earth’s.
  • Five of them are defined as super-Earths, meaning that they have a mass higher than that of our planet but significantly lower than Uranus or Neptune.
  • The remaining planet is described as a “mini-Neptune”, planets that are less massive than Neptune while still resembling the gas giant in our own solar system in terms of atmosphere and composition.
