Tulane University chemistry professor Igor Rubtsov and a team of graduate students can lay claim to inventing an important new scientific instrument — the world’s first fully automated dual-frequency, two-dimensional infrared spectrometer.

The whistle blows and the big game begins on TV. You watch the punted football sail over the field and into the arms of the opposing team—then the feed abruptly cuts out. The information blackout is apparently universal, with no coverage online or on the radio. Hours later, the signal returns and you learn that your beloved home team pulled off a stunning, come-from-behind victory. But here’s the kicker: there’s no way to find out the play-by-play. Did the quarterback’s last-second Hail-Mary pass decide the game, or was it a devastating interception returned for a touchdown?

Lawrence Livermore National Laboratory researchers have combined ultrafast time-resolved experimental measurements with theory to reveal how an explosive responds to a high-impact shock.

Hydrogen is a “green” fuel that burns cleanly and can generate electricity via fuel cells. One way to sustainably produce hydrogen is by splitting water molecules using the renewable power of sunlight, but scientists are still learning how to control and optimize this reaction with catalysts.
