متن کاملMolecular and ionic diffusion in aqueous - deep eutectic solvent mixtures: probing inter-molecular interactions using PFG NMR.
Pulsed field gradient (PFG) NMR has been used to probe self-diffusion of molecular and ionic species in aqueous mixtures of choline chloride (ChCl) based deep eutectic solvents (DESs), in order to elucidate the effect of water on motion and inter-molecular interactions between the different species in the mixtures, namely the Ch(+) cation and hydrogen bond donor (HBD). The results reveal an int...
متن کاملEmpirical solvent-mediated potentials hold for both intra-molecular and inter-molecular inter-residue interactions.
Whether knowledge-based intra-molecular inter-residue potentials are valid to represent inter-molecular interactions taking place at protein-protein interfaces has been questioned in several studies. Differences in the chain connectivity effect and in residue packing geometry between interfaces and single chain monomers have been pointed out as possible sources of distinct energetics for the tw...

Fig. 1 Self-diffusion coefficients of (+) methane, (x)ethane, (Δ)propane [7], and of (○)methanol [8] in NaCaA in comparison with the first results obtained with two different specimens of cation-free Si-LTA, viz. of (■)ethane and (▲)propane in specimen I and of (□)ethane, (⃟)ethene and (●)methanol in specimen II. 1. Introduction In elucidating the origin of the discrepancies in the message of d...
متن کاملNew Options for Measuring Molecular Diffusion in Zeolites by MAS PFG NMR
1. Introduction Combination of pulsed field gradient (PFG) NMR with magic-angle spinning (MAS) NMR is demonstrated to have remarkable advantages in comparison with conventional PFG NMR, if applied to diffusion measurements in beds of nanoporous particles, notably zeolites. These advantages are based on the effect of line narrowing and concern (i) a prolongation of the intervals during which the...
