Competitive Adsorption of Toluene and Water in MFI-type Zeolites
Gavriel Arbiv, Sambhu Radhakrishnan, Alysson F. Morais +6
Competitive adsorption is a major challenge in understanding catalytic activity, selectivity and reaction mechanisms in confined environments such as zeolites. This study investiga…
Rietveld Refinement and NMR Crystallographic Investigations of Multicomponent Crystals Containing Alkali Metal Chlorides and Urea
Cameron S. Vojvodin, Sean T. Holmes, Christine E. A. Kirschhock +8
New mechanochemical preparations of three multicomponent crystals (MCCs) of the form MCl:urea.nH2O (M = Li+, Na+, and Cs+) are reported. Their structures were determined by an NMR…
Amorphous to Crystalline Transformation: How Cluster Aggregation Drives the Multistep Nucleation of ZIF-8
Sambhu Radhakrishnan, Flip de Jong, Estelle Becquevort +11
Nucleation, the pivotal first step of crystallization, governs essential characteristics of crystallization products, including size distribution, morphology, and polymorphism. Whi…
High temperature 1H DOSY NMR reveals sourdough fermentation of wheat flour alters the molecular structure of water-extractable arabinoxylans
Pasquinel Weckx, Víctor González Alonso, Ewoud Vaneeckhaute +3
Arabinoxylans are constituents of wheat flour that contribute to the dietary fiber properties of wheat. They exist in water-extractable and water-unextractable forms and contribute…
Hydrated Silicate Ionic Liquids: Ionic Liquids for Silicate Material Synthesis
Dries Vandenabeele, Nikolaus Doppelhammer, Sambhu Radhakrishnan +7
The development of Hydrated Silicate Ionic Liquids, which are hypo-hydrated room temperature melts of alkali silicates, has created new opportunities for synthesizing porous silica…
A Simple Molecular Model for Hydrated Silicate Ionic Liquids, a Realistic Zeolite Precursor
Jelle Vekeman, Dries Vandenabeele, Nikolaus Doppelhammer +4
Despite the widespread use of zeolites in chemical industry, their formation process is not fully understood due to the complex and heterogeneous structure of traditional synthesis…
Can the combination of in situ differential impedance spectroscopy and 27Al NMR detect incongruent zeolite crystallization?
Dries Vandenabeele, Nikolaus Doppelhammer, Sambhu Radhakrishnan +4
Crystallizing zeolites with isotropic properties is critical to the chemical industry but can be extremely challenging as small deviations in the synthesis conditions can have extr…
Non-contact in situ multi-diagnostic NMR/dielectric spectroscopy
Alysson F. Morais, Sambhu Radhakrishnan, Gavriel Arbiv +5
Introduction of a dielectric material in an NMR probe head modifies the frequency response of the probe circuit, a phenomenon revealed by the detuning of the probe. For NMR spectro…
PolySilicate Porous Organic Polymers (PSiPOPs), a new family of porous, ordered 3D reticular materials with polysilicate nodes and organic linkers
Jelle Jamoul, Sam Smet, Sambhu Radhakrishnan +3
Spherosilicate, consisting of a double 4-ring cyclosilicate core (D4R; Si8O20) with every corner functionalized with a dimethylsilyl chloride group (-SiMe2Cl), was used as node to…
SI methane hydrate confined in C8-grafted SBA-15: A highly efficient storage system enabling ultrafast methane loading and unloading
Emile Jules Beckwée, Maarten Houlleberghs, Radu-George Ciocarlan +8
Confinement of water and methane in mesopores of hydrophobized SBA-15 is demonstrated to promote methane hydrate formation. In comparison to as-synthesized SBA-15, hydrophobization…
NMR crystallography reveals carbonate induced Al-ordering in ZnAl layered double hydroxide
Sambhu Radhakrishnan, Karl Lauwers, C. Vinod Chandran +5
Layered double hydroxides (LDHs) serve a score of applications in catalysis, drug delivery, and environmental remediation. Smarter crystallography, combining X-ray diffraction and…
