![Illustration of propane oxidative dehydrogenation pathways on the catalyst surface and in the gas phase.](/sites/default/files/styles/list_page_thumbnail/public/2020-07/Picture6.png?h=0f46b1d3&itok=u2QCLHK5)
Direct experimental evidence of gas-phase methyl radicals in propane oxidative dehydrogenation (ODHP) combined with density functional theory (DFT) calculations uncovers the mechanism behind the exceptional selectivity to olefins over BN catalysts
Scientists from ORNL and several Japanese laboratories have developed an experimental method for fast determination of the optimum heavy-ion beam energy for the synthesis of super heavy elements.
![Bubbling a flue gas mixture through an aqueous solution of a simple bis-iminoguanidine (GBIG) leads to CO2 capture as a crystalline bicarbonate salt. The X-ray crystal structure revealed ‘anti-electrostatic’ bicarbonate dimers stabilized by hydrogen bonding from guanidinium cations and water. Mild heating of the crystals releases the CO2 and regenerates the GBIG sorbent quantitatively so it can be recycled.](/sites/default/files/styles/list_page_thumbnail/public/2019-04/RC_Chem_2019%20thmnlw_0.jpg?h=15cf103d&itok=vOrZWilO)
