Einsteinium

Why in News?

Scientists at the California-based Berkeley Laboratory studied the properties of element having atomic number of 99 in the periodic table which is called ‘Einsteinium’ after Albert Einstein.

After this study, for the first time researchers have been able to characterize the ‘properties of the elements’.

This team of scientists studied ‘Einsteinium-254’, one of the more stable isotopes of the element, which has a half-life of 276 days. ‘Einsteinium 253’, the most common isotope of Einsteinium, has a half-life of 20 days.

This element has eroded due to high radioactivity and short lifetime of all isotopes and is no longer found naturally, but can be produced by intensive and precise chemical processes.

This element was discovered in the year 1952 from the debris obtained after the explosion of first hydrogen bomb.

  • The explosion occurred in a thermonuclear device called ‘Ivy Mike’ during a test on an island called Elugelab, located on ‘Anivetok Atoll’ in the South Pacific Ocean, which was 500 times more devastating than the explosion in Nagasaki.

  • Currently this element is available in limited quantities, which can be used only for scientific research.
  • It cannot be seen with the naked eye. After this research, scientists have been able to understand the complexity of bonds with other atoms of this element using an exact X-ray produced by the Particle Accelerator.
  • By studying this atomic system, scientists can find out the important chemical properties of other elements and its isotopes, which can be useful for nuclear power generation and radiopharmaceutical.

Facts  For Prelims:

The City Innovation Exchange (CiX) platform was launched by Shri Durga Shanker Mishra, Secretary, Ministry of Housing and Urban Affairs at an online event here today.

  • The platform will be a significant addition to the growing innovationecosystem of India and focuses on fostering innovative practices in cities.

KOTIA CLUSTER:

Andhra Pradesh held panchayat elections in three villages in the Kotia cluster, which is at the centre of a dispute between Andhra Pradesh and Odisha. This is the first time Andhra has held panchayat polls in any of these villages.

About:

  • These villages, with a population of nearly 5,000, are located on a remote hilltop on the inter-state border and are inhabited by Kondh tribals.
  • The region is also rich in mineral resources like gold, platinum, manganese, bauxite, graphite and limestone.
  • In the early 1980s, Odisha filed a case in the Supreme Court demanding right and possession of jurisdiction over the 21 villages.
  • In 2006 however, the court ruled that since disputes belonging to the state boundaries are not within the jurisdiction of the Supreme Court, the matter can only be resolved by Parliament and passed a permanent injunction on the disputed area.
