New iCOF material selectively sequesters Cr(VI) oxoanions in the presence of other anions, such as sulfate and nitrate.
The clusters are assembled through steric and electrostatic forces, with the chloride anions (green spheres) residing in equidistant ‘clefts’ between coordinating diglycolamide ligands in positions that satisfy both repulsive and attractive ion-ion
OAK RIDGE, Tenn., May 2, 2018—The search for a more energy efficient and environmentally friendly method of ammonia production for fertilizer has led to the discovery of a new type of catalytic reaction.
A shield assembly that protects an instrument measuring ion and electron fluxes for a NASA mission to touch the Sun was tested in extreme experimental environments at 91°µÍø—and passed with flying colors.
Direct air capture of CO2 via aqueous-phase absorption and crystalline-phase release
Scientists have unraveled details of the mechanism of mechanical reinforcement in glassy polymer nanocomposites.1 Measurements in the interfacial layer ~2–4 nm around nanoparticles revealed that Young’s modulus, which defines the relationship between
Researchers have demonstrated a process to prepare morphologically tailored carbon materials with good electrochemical capacity and stability for sodium-ion battery anodes.
Scientific Achievement
Found that, when confined in the ~ 5 Ã… wide channels in a beryl crystal, the water molecule undergoes quantum tunneling between six symmetrically equivalent positions around the c-axis in the structure.
