Low-Temperature Dynamics of Water Confined in Unidirectional Hydrophilic Zeolite Nanopores

Livia Eleonora Bove Kado, Umbertoluca Ranieri, Maria Rescigno

The dynamical properties of water molecules confinedin the unidirectionalhydrophilic nanopores of AlPO4-54 are investigated withquasi-elastic neutron scattering as a function of temperature downto 118 K. AlPO4-54 has among the largest pores known foralumin ...

CHD3 Dissociation on the Kinked Pt(210) Surface: A Comparison of Experiment and Theory

Rainer Beck, Ana Gutiérrez González, Helen Jane Chadwick

To be able to simulate activated heterogeneously catalyzed reactions on the edge and corner sites of nanoparticles, a method for calculating accurate activation barriers for the reactions is required. We have recently demonstrated that a semiempirical spec ...

Transferability of the SRP32-vdW specific reaction parameter functional to CHD3 dissociation on Pt(110)-(2 × 1)

Rainer Beck, Ana Gutiérrez González, Helen Jane Chadwick

Stepped transition metal surfaces, including the reconstructed Pt(110)-(2 × 1) surface, can be used to model the effect of line defects on cata- lysts. We present a combined experimental and theoretical study of CHD3 dissociation on this surface. Theoretic ...

Biporous Metal-Organic Framework with Tunable CO2/CH4 Separation Performance Facilitated by Intrinsic Flexibility

Berend Smit, Kyriakos Stylianou, Seyedmohamad Moosavi, Daniele Ongari, Peter George Boyd, Andrzej Gladysiak, Arunraj Chidambaram, Kathryn Suzanne Deeg, Kaili Yee Ordiz

In this work, we report the synthesis of SION-8, a novel metal-organic framework (MOF) based on Ca(II) and a tetracarboxylate ligand TBAPy(4-) endowed with two chemically distinct types of pores characterized by their hydrophobic and hydrophilic properties ...

The Structure of the Protonated Serine Octamer

Ursula Röthlisberger, Thomas Rizzo, Stephan Warnke, Marta Andreia Da Silva Perez, Valeriu Scutelnic, Aurelien Stephen Arnaud Gregor, Carsten Baldauf

The amino acid serine has long been known to form a protonated “magic-number” cluster containing eight monomer units that shows an unusually high abundance in mass spectra and has a remarkable homochiral preference. Despite many experimental and theoretica ...

Bond selective dissociation of methane (CH3D) on the steps and terraces of Pt(211)

Rainer Beck, Ana Gutiérrez González, Fleming Crim

The dissociative chemisorption of singly deuterated methane (CH3D) has been studied on the steps and terraces of a Pt(211) surface by quantum state resolved molecular beam methods. At incident translational energy (Et) below 50 kJ/mol, CH3D dissociates onl ...

Kinetics of calcium sulfoaluminate with 1% iron oxide by isothermal and isoconversional methods

Xuerun Li, Yu Zhang

The influence of iron oxide (Fe2O3) on the formation and decomposition kinetics of calcium sulfoaluminate (C(4)A(3)$) formed from tricalcium aluminate and calcium sulfate was investigated by both isothermal and isoconversional methods. Rietveld quantitativ ...

High diffusion barrier and piezoelectric nanocomposites based on polyvinylidene fluoride-trifluoroethylene copolymer and hydrophobized clay

Yves Leterrier, Dragan Damjanovic, Sara Dalle Vacche, Antonia Neels, Olha Sereda, Alex Dommann

Nanocomposites based on polyvinylidene fluoride– trifluoroethylene copolymer and up to 4 vol % of hydrophobized clay nanoparticles are investigated. The structure, piezoelectric properties, and oxygen permeability of solvent cast films are analyzed before ...

Impact of the strength and spatial distribution of adsorption sites on methane deliverable capacity in nanoporous materials

Berend Smit, Cory Matthew Simon

The methane deliverable capacity of adsorbent materials is a critical performance metric that will determine the viability of using adsorbed natural gas (ANG) technology in vehicular applications. ARPA-E recently set a target deliverable capacity of 315 cc ...

Complexation of [Gd(DTTA–Me)(H2O)2]− by Fluoride and Its Consequences to Water Exchange

Lothar Helm, Loïck Moriggi, Shima Karimi, Gail Ruth Hunter

The displacement of water molecule(s) from the inner coordination sphere of [Gd(DTTA–Me)(H2O)2]− (DTTA = ethylenetriamine-N,N,N″,N″-tetraacetate) by fluoride has been studied by multinuclear NMR relaxation (1H, 17O, 19F) and DFT calculations. Fluoride anio ...
