Kristina Verdal, Terrence J. Udovic, John J. Rush, Vitalie Stavila, Hui Wu, Wei Zhou, Timothy Jenkins
Low-temperature neutron scattering spectra of diammonium dodecahydro-closo-dodecaborate [(NH4)2B12H12] reveal two NH 4 + rotational tunneling peaks (e.g., 18.5 υeV and 37 υeV at 4 K), consistent with the tetrahedral symmetry and environment of the cations

Metal Amidoboranes

Author(s)
Hui Wu, Wei Zhou, Taner Yildirim
Metal amidoboranes, consisting of [NH 2BH 3]- anion and various metal cations, are a new class of compounds that have recently attracted great attentions due to their intriguing crystal structures and novel chemical and physical properties. Similar to

Carbon Capture in Metal-Organic Frameworks - A Comparative Study

April 21, 2011
Author(s)
Jason M. Simmons, Hui Wu, Wei Zhou, Taner Yildirim
Metal organic frameworks (MOFs) have been shown to be excellent materials for storage of carbon dioxide, implying that they could be useful for removal of carbon dioxide from flue gas stacks, however their performance in industrial relevant swing

Reorientational Dynamics of the Dodecahydro-Closo-Codecaborate Anion in Cs 2 B 12 H 12

March 17, 2011
Author(s)
Kristina Verdal, Terrence J. Udovic, John J. Rush, Ronald L. Cappelletti, Wei Zhou
Rapid reorientational motions of the B12H122- icosahedral anion, a key intermediate in borohydride dehydrogenation, are revealed by quasielastic neutron scattering (QENS) measurements of Cs2B12H12 between 430 K and 530 K. At 430 K, over the range of

Dehydrogenation Tuning of Ammine Borohydrides using Double-Metal Cations

March 10, 2011
Author(s)
Yanhui Guo, Hui Wu, Wei Zhou, Xuebin Yu
The strategy of using double-cation to tune the temperature and purity of dehydrogenation of ammine borohydrides is reported. The first double-cation ammine borohydride, Li 2Al(BH 4) 5¿6NH 3, which forms a novel structure with ordered arrangement of Al(NH
