Structural characterization and X-ray reference powder pattern determination have been condcuted for the Co- and Zn-containing tridymite derivatives Ba(Co1-xZnx)SiO4 (x = 0.2, 0.4, 0.6, 0.8). The bright blue series of Ba(Co1-xZnx)SiO4 crystallized in the

Carbon Capture and Storage Properties of Porous Octahedral Molecular Sieve

Matthew Lawson, Jarod C. Horn, Winnie Wong-Ng, Laura Espinal, Huong Giang Nguyen, James A. Kaduk, Saul H. Lapidus, Yongtao Meng, Steven L. Suib, Lan Li
Based on the experimentally determined framework structure of porous MnO2 octahedral molecular sieve (OMS)-5, we used density functional theory-based calculations to evaluate the effect of Na+ cation on pore dimensionality and structural stability, and the

This paper reports the structural basis of CO2 adsorption in a representative model flexible metal organic framework (MOF) material, Ni(1,2-bis(4-pyridyl)ethylene)[Ni(CN)4] (NiBpene or PICNIC-60). NiBpene exhibits a CO2 sorption isotherm with

Control of thermal expansion in a low-density framework modification of silicon

Beekman Mathew, James A. Kaduk, Winnie Wong-Ng, George S. Nolas
The low-density clathrate-II modification of silicon, Si136, contains two distinct cage-like voids large enough to accommodate various types of guest atoms which influence both the host structure and its properties. Although the linear coefficient of

Electronic Structure, Pore Size Distribution, and Sorption Characterization of an unusual MOF, {[Ni(dpbz)][Ni(CN)4]}n, dpbz=1,4-bis(4-pyridyl)benzene

September 26, 2018
Author(s)
Winnie K. Wong-Ng, Izaak Williamson, Daniel W. Siderius, Jeffrey T. Culp, Yu-Sheng Chen, Lan Li, Matthew Lawson
The monoclinic (Ni(L)[Ni(CN)4] (L= 1,4-Bis(4-pyridyl) benzene) compound (nick-name Ni-dpbz) is a flexible metal organic framework (MOF) which assumes a pillared structure with layers defined by 2D Ni[Ni(CN)4]n nets and dpbz ligands as pillars. The

Ba8Cu16As30: A cationic-framework clathrate-I arsenide

August 10, 2018
Author(s)
Kaya Wei, Artem R. Khabibullin, Dean Hobbis, Winnie Wong-Ng, Tieyan Chang, SuYin G. Wang, Igor Levin, Yu-Sheng Chen, Lilia M. Woods, George S. Nolas
Single crystals of clathrate-I Ba8Cu16As30 have been synthesized, and their structure and electronic properties deter-mined using synchrotron-based X-ray diffraction and first principles calculations. The structure is confirmed to be cubic and defined by a

Materials and Processes for CO2 Capture, Conversion and Sequestration

May 26, 2018
Author(s)
Winnie K. Wong-Ng, Lan Li, Lawrence P. Cook, Kevin Huang
The book “Materials and Processes for CO2 Capture, Conversion and Sequestration (CCS)” which will be published by John Wiley & Sons, Inc., is a result of the symposium of the same title which took place in 2014 during the MS&T (Materials Science and
