New Salt Compounds Challenge the Foundation of Chemistry

All good research breaks new ground, but rarely does the research unearth truths that challenge the foundation of a science. That’s what Artem R. Oganov has done, and the professor of theoretical crystallography in the Department of Geosciences will have his work published in the Dec. 20 issue of the journal Science.

The paper titled "Unexpected stable stoichiometries of sodium chlorides,” documents his predictions about, and experiments in, compressing sodium chloride—rock salt—to form new compounds. These compounds validate his methodology for predicting the properties of objects—a methodology now used worldwide for computational material discovery—and hold the promise of novel materials and applications.

Thank you for writing to "Chemical Science"

Message from Bhagavath Geetha
  • Do not get over excited over happiness and do not get over depressed over sorrow.
  • Do not get over bonded with anyone and anybody because it can lead to problems and sorrow.
  • Never think that my duty is the topmost or lowermost. Every duty is respectful. The responsibility undertaken or given as per the position is the noblest duty.
