Understanding Gas Storage in Cuboctahedral Porous Coordination Cages

July 4, 2019
Author(s)
Gregory R. Lorzing, Eric J. Gosselin, Benjamin Trump, Arthur H. P. York, Arni Sturluson, Casey A. Rowland, Glenn P. A. Yap, Craig Brown, Cory M. Simon, Eric D. Bloch
Porous molecular solids are promising molecular solids are promising materials for gas storage applications. However, given the relative dearth of studies concerning these materials in this regard, additional adsorption and structural studies are vital for

Incommensurate Magnetism near Quantum Criticality in CeNiAsO

Shan Wu, W. A. Phelan, L. Liu, J. R. Morey, J. A. Tutmaher, J. C. Neuefeind, Ashfia Huq, Matthew B. Stone, M. Feygenson, David W. Tam, Benjamin A. Frandsen, Benjamin Trump, Cheng Wan, S. R. Dunsiger, Tyrel M. McQueen, Y. J. Uemura, Collin L. Broholm

Methane Storage in Paddlewheel-Based Porous Coordination Cages

August 18, 2018
Author(s)
Casey A. Rowland, Gregory R. Lorzing, Eric J. Gosselin, Benjamin Trump, Glenn P. A. Yap, Craig Brown, Eric D. Bloch
Although gas adsorption properties of extended three-dimensional metal-organic materials have been widely studied, they remain relatively unexplored in porous molecular systems. This is particularly the case for porous coordination cages which typically

Nature of Decahydro-Closo-Decaborate Anion Reorientations in an Ordered Alkali-Metal Salt: Rb 2 B 10 H 10

July 12, 2018
Author(s)
Mirjana NMN Dimitrievska, Vitalie Stavila, Alexei V. Soloninin, Roman V. Skoryunov, Olga A. Babanova, Hui Wu, Wei Zhou, Wan Si Tang, Antonio Faraone, Jacob Daniel Tarver, Benjamin Trump, Alexander V. Skripov, Terrence J. Udovic
The ordered monoclinic phase of the alkali-metal decahydro-closodecaborate salt Rb 2B 10H 10 was found to be stable from about 250 K all the way up to an order-disorder phase transition temperature of approximately equal} 762 K. The broad temperature range

Universal Geometric Frustration in Pyrochlores

July 5, 2018

Benjamin A Trump, Syed M. Koohpayeh, Ken J. T. Livi, JiaJia Wen, Kathyrn Arpino, Quentin M. Ramasse, Rik Brydson, Mikhail Feygenson, H. Takeda, M. Takigawa, K. Kimura, S. Nakatsuji, Collin L. Broholm, T. M. McQueen
We report on the structural details of Pr 2Zr 2O 6O', La 2Zr 2O 6O', and Yb 2Ti 2O 6O' in the A 2B 2O 6O' pyrochlore structure. X-ray and neutron powder diffraction indicate these materials are long-range ordered. On the local scale these materials appear

Gas Adsorption in an Isostructural Series of Pillared Coordination Cages

June 21, 2018
Author(s)
Eric J. Gosselin, Gregory R. Lorzing, Benjamin Trump, Craig Brown, Eric D. Bloch
The synthesis and characterization of six novel pillared metal-organic polyhedra is reported. By utilizing dabco (1,4-diazabicyclo[2.2.2.]octane), a pillar with increased basicity as compared to typical pillars such as pyrazine, three new stable copper

Selective Gas Adsorption in Highly Porous Chromium(II)-Based Metal-Organic Polyhedra

September 27, 2017
Author(s)
Gregory R. Lorzing, Benjamin Trump, Craig Brown, Eric D. Bloch
The synthesis and characterization of two novel chromium(II)-based cuboctahedral metal-organic polyhedra is reported. The alkane functionalized analog, Cr_ tBu-bdc ( tBu-bdc = 5-tertbutylbenzene-1,3-dicarboxylate) exhibits excellent thermal stability
