Mechanistic Study of Zeolite Crystallization Published in Nat. Commun.

In this manuscript we use scanning probe microscopy to monitor zeolite LTA crystallization in situ with a spatiotemporal resolution that captures dynamic processes in real time. We report a distinctive pathway involving the formation of gel-like islands from supersaturated solutions comprised of (alumino)silicate molecules. Three-dimensional assembly and evolution of these islands constitutes a unique mode of growth that differs from classical theories. Time-resolved imaging also reveals that growth can occur by (nearly) oriented attachment. At later stages of crystallization, a progressive transition to lower supersaturation shifts growth to a layered mechanism involving two-dimensional nucleation and spreading of layers.

2018 Norman Hackerman Award

Jeff received the 2018 Norman Hackerman Award in Chemical Research from the Welch Foundation. The description for the award is the following along with pictures form the award ceremony that was held at the University of Houston Hilton Hotel:

“Dr. Rimer’s lab has made two significant materials science research discoveries in the past decade. The discovery of a molecule that inhibits calcium oxalate crystallization, the principal component of kidney stones, may lead to a promising therapeutic that has the potential to replace drugs currently used to treat this widespread disease. The second notable discovery is inspiring new methods to optimize the synthesis of zeolites, which are important as catalysts in petrochemical industries.”

About the Cover: The driving forces governing the morphology of metal oxide particles exposing polar facets via the decomposition of suitable precursors in air, molten salts, ionic liquids, or other media are not fully understood. In this article, the authors investigate the thermal decomposition of MgO precursors in molten salts to assess the influence of precursor decomposition pathways, including the physical state of the reaction intermediates and the possibility of dissolution−recrystallization processes in the formation of octahedral MgO particles. It is shown that the presence of residual water and ions impact MgO(111) crystallization in ways that still remain elusive but are not necessarily governed by dsorption−stabilization processes. The cover illustrates that the formation of polar MgO(111) crystals is facilitated in molten salt media when MgO is generated via a liquid-to-solid reaction with intermediates in the molten state.

This work examines the inhibition of pathological crystallization, focusing on calcium oxalate monohydrate (the principal component of human kidney stone disease). Here we present a new mechanism of crystal growth inhibition (strain-induced dissolution) and identify a compound that has the potential to be a new treatment of calcium oxalate kidney stones. Coauthors of this manuscript include Jihae Chung (UH, first author), Yanni Mpourmpakis (Univ. Pittsburgh), and John Asplin (Litholink Corporation). For details, see the Nature website: Abstract
