The Synthesis of Ba‐ and Fe‐ Substituted CsAlSi₂O₆ Pollucites

Journal of the American Ceramic Society (2013)

Mark A. Rodriguez Terry J. Garino David Rademacher Xiaoyi Zhang Tina M. Nenoff

Barium‐substituted CsAlSi 2 O 6 pollucites, Cs x Ba (1− x )/2 AlSi 2 O 6 , and barium‐ and iron‐substituted pollucites, Cs x Ba (1− x )/2 Al x Fe 1− x Si 2 O 6 and Cs x Ba 1− x Al x Fe 1− x Si 2 O 6 were synthesized with 1 ≥ x ≥ 0.7 using a hydrothermal synthesis procedure. Rietveld analysis of X ‐ray diffraction data confirmed the substitution of Ba for Cs and Fe for Al , respectively. The crystallographic analysis also describes the effects of three different types of pollucite substitutions on the pollucite unit cell: Ba 2+ for Cs 1+ cation results in little effect on cell dimensions, intermediate concentrations of Ba 2+ and Fe 3+ substitution result in net minor expansion due to Fe 3+ addition, and large Ba and Fe substitutions result in overall framework contraction. Elemental analysis combined with microscopy further supports the phase purity of these new phases. These materials can be used to study the stability of CsAlSi 2 O 6 as a durable ceramic waste form, which could accommodate with time Cs and its decay product, Ba . Furthermore, success in iron substitution for aluminum into the pollucite lattice predicts that redox charge compensation for Cs cation decay is possible.

Mechanistic Source Term Considerations for Advanced Non-LWRs

Nathan Andrews Tina M. Nenoff David Luxat Andrew Clark Jennifer Leute

This report is a functional review of the radionuclide containment strategies of fluoride-salt-cooled high temperature reactor (FHR), molten salt reactor (IVISR) and high temperature gas reactor (HTGR) systems. This analysis serves as a starting point for further, more in-depth analyses geared towards identifying phenomenological gaps that still exist, preventing the creation of a mechanistic source term for these reactor types. As background information to this review, an overview of how a mechanistic source term is created and used for consequence assessment necessary for licensing is provided. How mechanistic source term is used within the LMP is also provided. Third, the characteristics of non-LWR mechanistic source terms are examined This report does not assess the viability of any software system for use with advanced reactor designs, but instead covers system function requirements. Future work within the Nuclear Energy Advanced Modeling and Simulations (NEAMS) program will address such gaps.

[CN3H6]2[Zn(CO3)2], the first organically templated open-framework carbonate

Journal of the Chemical Society Dalton Transactions (2001)

William T. A. Harrison Mark L. F. Phillips Tina M. Nenoff E.J. MacLean Simon J. Teat

[CN3H6]2[Zn(CO3)2], the first organically templated open-framework carbonate has been synthesized hydrothermally and its single crystal structure and some properties have been determined. This phase is built up from a three-dimensional framework of vertex-linked ZnO4 and CO3 building units encapsulating the extra-framework guanidinium cations. Template-to-framework hydrogen bonding appears to play an important role in stabilizing the structure. The zincocarbonate framework shows a surprising similarity to those of known zinc phosphates and phosphites.

Branched vs. linear hydrocarbon separations with novel modified zeolites.

Gary R. Gray Richard D. Noble Tina M. Nenoff Manuel Arruebo Mutlu Ulutagay‐Kartin

Conclusions of this paper are: (1) Adsorption/desorption on bulk unmodified zeolites showed isoprene adsorbed by zeolite-L and n-pentane adsorbed by zeolite-Y and ZSM-5; (2) Bulk carbonization is used to passivate zeolite activity toward organic adsorption/decomposition; (3) Based on the bulk modified zeolite separation results, we have determined that the MFI type has the most potential for isoprene enrichment; (4) Modified MFI type membranes are jointly made by Sandia and the Univ. of Colorado. Separation experiments are performed by Goodyear Chemical; (5) Isoprene/n-pentane separations have been demonstrated by using both zeolite membranes and modified bulk zeolites at various temperatures on the Goodyear Pilot-scale unit; and (6) Target zeolite membrane separations values of 6.7% isoprene enrichment have been established by economic analysis calculations by Burns & McDonnell.

Capturing CO2 via reactions in nanopores.

Kevin Leung Tina M. Nenoff Louise Criscenti Zhipeng Tang Junhang Dong

This one-year exploratory LDRD aims to provide fundamental understanding of the mechanism of CO2 scrubbing platforms that will reduce green house gas emission and mitigate the effect of climate change. The project builds on the team members expertise developed in previous LDRD projects to study the capture or preferential retention of CO2 in nanoporous membranes and on metal oxide surfaces. We apply Density Functional Theory and ab initio molecular dynamics techniques to model the binding of CO2 on MgO and CaO (100) surfaces and inside water-filled, amine group functionalized silica nanopores. The results elucidate the mechanisms of CO2 trapping and clarify some confusion in the literature. Our work identifies key future calculations that will have the greatest impact on CO2 capture technologies, and provides guidance to science-based design of platforms that can separate the green house gas CO2 from power plant exhaust or even from the atmosphere. Experimentally, we modify commercial MFI zeolite membranes and find that they preferentially transmit H2 over CO2 by a factor of 34. Since zeolite has potential catalytic capability to crack hydrocarbons into CO2 and H2, this finding paves the way for zeolite membranes that can convert biofuel into H2 and separate the products all in one step.
