  • 7Li spin-echo NMR diffusion studies
    • Abstract: Publication date: Available online 23 May 2019Source: Annual Reports on NMR SpectroscopyAuthor(s): Kikuko Hayamizu In electrochemistry, the important physical constants are ionic conductivity, viscosity and ion diffusion constants. Although the ionic conductivity (σ) and viscosity (η) have been widely obtained, measurements of diffusion constant (D) became recently possible by the pulsed field gradient (PFG) NMR method. The relations between D and η and D and σ are described by the Stokes-Einstein and Nernst-Einstein equations, respectively. The research and development of the Li-ion battery (LIB) is one of the most popular subjects and the observation of ion diffusion constants by the PFG-NMR methods became a state-of-the-art technique. In this chapter, PFG-NMR measurements of the diffusion constants of Li+, and the related anions and solvents of solution electrolytes and Li+, cations and anions in ionic liquids, as well as Li+ diffusion phenomena in inorganic solid electrolytes will be described.
  • Diffusion NMR spectroscopy applied to coordination and organometallic
    • Abstract: Publication date: Available online 22 May 2019Source: Annual Reports on NMR SpectroscopyAuthor(s): Álvaro Raya-Barón, Pascual Oña-Burgos, Ignacio Fernández This chapter illustrates an extensive review of the application of diffusion NMR techniques on coordination compounds and organometallic systems that gives an idea of the extraordinary progress that this field has achieved, whether using PGSE or DOSY methodologies. The estimation of diffusion parameters using all the advantages of high-resolution NMR spectroscopy specially with modern probeheads, that allow the use of intense gradient fields and the tuning of less conventional nuclei, have begun new perspectives to determine the size and shape of many molecular systems in solution. In both, supramolecular architectures or smaller metallic complexes, this type of measurements allows one to assess their aggregation state, character of intermolecular interactions, stability or association constants between different hosts and guests, among many other interesting features. The main aim of this review is to present an overview of the PGSE and DOSY NMR mapping and its applications in inorganic systems, specifically coordination compounds based on transition metals, alkaline, alkaline-earth, main-group, and rare earth metal centres, as well as cluster complexes and metal-based supramolecular structures. A brief introduction to pulse-field gradient NMR is also given, with special emphasis on the methodological procedures that can be used to obtain good quality data, providing different possibilities when choosing different variables, such as the correct pulse sequence or the right equation that govern both the friction and/or shape factor. The material given in this review are appealing in its simplicity, offer chemically useful results and we believe they should significantly boost the use of diffusion NMR measurements.
  • Recent NMR/MRI studies of biofilm structures and dynamics
    • Abstract: Publication date: Available online 23 April 2019Source: Annual Reports on NMR SpectroscopyAuthor(s): Maria Pia Herrling, Susanne Lackner, Hermann Nirschl, Harald Horn, Gisela Guthausen Biofilm systems consist of complex microbial communities embedded in hydrated bio-macromolecules. These biological systems have been studied by diverse analytical techniques, among them by nuclear magnetic resonance and imaging. There are still open questions regarding structure and functionality. In this review, nuclear magnetic resonance approaches, especially in form of magnetic resonance imaging and diffusion modalities, are summarized with respect to insights into biofilm structure, diffusion and advection, i.e. mass transport. Furthermore, possibilities and limitations regarding metabolomics are recapitulated and analysed with respect to open research questions. Perspectives for biofilm research will be discussed from the point of view of current technical and methodical developments of nuclear magnetic resonance. The impact of the named nuclear magnetic resonance techniques will be reflected in the context of water treatment and biofilm development in porous media as well as in technical applications such as biofilm reactors and biofiltration.
  • Solid-state NMR of nanocrystals
    • Abstract: Publication date: Available online 4 February 2019Source: Annual Reports on NMR SpectroscopyAuthor(s): Torsten Gutmann, Pedro B. Groszewicz, Gerd Buntkowsky Recent advances in solid-state nuclear magnetic resonance (NMR) spectroscopy and dynamic nuclear polarization (DNP) of nanostructured materials are reviewed. A first group of materials is based on crystalline nanocellulose (CNC) or microcrystalline cellulose (MCC), which are used as carrier materials for dye molecules, catalysts or in combination with heterocyclic molecules as ion conducting membranes. These materials have widespread applications in sensorics, optics, catalysis or fuel cell research. A second group are metal oxides such as V-Mo-W oxides, which are of enormous importance in the manufacturing process of basic chemicals. The third group are catalytically active nanocrystalline metal nanoparticles, coated with protectants or embedded in polymers. The last group includes of lead-free perovskite materials, which are employed as environmentally benign substitution materials for conventional lead-based electronics materials. These materials are discussed in terms of their application and physico-chemical characterization by solid-state NMR techniques, combined with gas-phase NMR and quantum-chemical modelling on the density functional theory (DFT) level. The application of multinuclear 1H, 2H, 13C, 15N and 23Na solid state NMR techniques under static or MAS conditions for the characterization of these materials, their surfaces and processes on their surfaces is discussed. Moreover, the analytic power of the combination of these techniques with DNP for the identification of low-concentrated carbon and nitrogen containing surface species in natural abundance is reviewed. Finally, approaches for sensitivity enhancement by DNP of quadrupolar nuclei such as 17O and 51V are presented that enable the identification of catalytic sites in metal oxide catalysts.
  • NMR as a powerful tool to study lithium ion battery electrolytes
    • Abstract: Publication date: Available online 30 January 2019Source: Annual Reports on NMR SpectroscopyAuthor(s): Simon Wiemers-Meyer, Martin Winter, Sascha Nowak The properties of a lithium ion battery (LIB) are determined by the interplay of its components. In this regard, it is essential to understand the interactive behaviour of the electrolyte as it interacts with both the positive and the negative electrode as well as with the separator and other inactive cell components. The behaviour of LIB electrolytes including their chemical and electrochemical reactions can be monitored by means of numerous analytical techniques. NMR spectroscopy demonstrated to be one of the most powerful analysis methods. Analysing LIB electrolytes appeared very challenging, as they generate many reaction products that are highly reactive, particularly in the presence of water. In this regard, NMR spectroscopy proved itself valuable since it enables contact-free measurements of samples inside protective vessels. This review describes the progress in analysing LIB electrolytes starting from qualitative studies on the formation of degradation products. Additionally, it includes early quantitative studies to gain deeper insights into chemical reactions as well as the development of new NMR methods providing results that partially revise previous works. Finally, in situ NMR methods that enable the analysis of electrolytes inside of an intact battery cell are discussed.
  • Ultrafast NMR diffusion and relaxation studies
    • Abstract: Publication date: Available online 30 January 2019Source: Annual Reports on NMR SpectroscopyAuthor(s): Ville-Veikko Telkki, Vladimir V. Zhivonitko Relaxation and diffusion NMR experiments, called also Laplace NMR experiments, provide detailed information about rotational and translational motion of molecules. Furthermore, they offer chemical resolution complementary to spectra. The resolution and information content of the experiments can be improved by a multidimensional approach. The approach enables one to determine the correlations between the relaxation and diffusion parameters and study chemical or physical exchange. However, the multidimensional approach is slow, as the experiment has to be repeated many times with incremented evolution time. In the ultrafast Laplace NMR method, the various evolution times are encoded into layers of the sample. This enables one to measure multidimensional data in a single scan, reducing the experiment time by one to three orders of magnitude. In addition, the single-scan approach facilitates significantly the use of modern hyperpolarization methods to increase the sensitivity of the experiment by several orders of magnitude. This review describes the principles of ultrafast Laplace NMR and highlights its applications in various disciplines, including those using low-field, mobile, single-sided NMR instruments.
  • Recent Developments in Absolute Shielding Scales for NMR Spectroscopy
    • Abstract: Publication date: Available online 22 January 2019Source: Annual Reports on NMR SpectroscopyAuthor(s): Gustavo A. Aucar, I. Agustín Aucar The absolute value of the nuclear magnetic shielding tensor, σ, cannot be directly measured as such, though at the moment experimental devices are available to obtain them by extrapolation to zero-density limit. This is the reason why since the beginning of NMR spectroscopy to obtain the experimental values of this parameter required the interplay between theory and experiments.Early this century it was experimentally probed that the Ramsey–Flygare model, largely used to obtain the most accurate semiexperimental values of shieldings, does not work well when heavy-atom containing molecules are considered. Then, the search for a relativistic relationship like Ramsey–Flygare became highly necessary. This search has taken some years for being successful.Within the research programme that focused on such a goal, the first important breakthrough was the finding of the relativistic Hamiltonian for spin–rotations interactions. Once this crucial step was overcome it was possible to develop some relativistic models, being the most accurate the so-called M-V. We shall show here some of the most important steps that were given in the search for a relativistic relationship between σ and the spin–rotation tensor, M. We will describe the bottom-up procedure that make it possible, together with relativistic (four-component) theories of shieldings and spin–rotations that were published recently.Why it was important to find that new relationship' There are now experimental developments that permits direct measurements of absolute shieldings in gas-phase NMR spectroscopy, and so, to compare with. It is also possible to accurately calculate them by using four-component methodologies, from which very small effects like nuclear charge distribution, Breit/Gaunt electron–electron interactions and QED effects are included. All of them will be highlighted here in some detail.Lastly we shall stress the new understandings that arise from these developments together with some new challenges.
  • Mixed Network Phosphate Glasses: Seeing Beyond the 1D 31P MAS-NMR Spectra
           With 2D X/31P NMR Correlation Maps
    • Abstract: Publication date: Available online 28 December 2018Source: Annual Reports on NMR SpectroscopyAuthor(s): Grégory Tricot Much attention has been devoted to mixed network phosphate glasses during the last decades. Compared to simple network phosphate glasses, this type of glass presents interesting properties and improved stability deriving from the synergic association between P2O5 and another glass network former oxide. While solid state NMR appears to be the technique of choice to investigate both local and medium range structures of these materials, standard 1D 31P MAS-NMR spectra appear to be composed of very broad and uninformative signals coming from the superimposition of several resonances with close chemical shift values. The 1D NMR experiments do not provide interesting information and, as a consequence, the derived structural characterisation is limited and does not allow for a deep understanding of the macroscopic properties of these materials. In this review, we will present how the editing of 2D 31P/X correlation maps can overcome the poor resolution of the 1D 31P NMR analysis to provide detailed structural data. Through different examples, we will show how the 2D maps can be used to better understand the complex structure of these glasses and to help in the 1D 31P MAS-NMR analysis by (i) numbering the number of phosphate species, (ii) distinguishing P atoms involved in P–O–P and P–O–X bonds, and (iii) extracting NMR parameters (δCS, broadness) that will be used as input data for a supported and efficient 1D 31P NMR spectrum decomposition.
  • Applications of Hyperpolarisation and NMR Long-Lived States in Drug
    • Abstract: Publication date: Available online 26 December 2018Source: Annual Reports on NMR SpectroscopyAuthor(s): Nicola Salvi NMR is routinely employed in drug development, especially in the early stage of fragment-based drug discovery, when weakly binding molecules in a large pool of fragments have to be identified. Here we review recent progress in the use of long-lived states and coherences, spin states that relax more slowly than longitudinal magnetisation and single-quantum coherences, respectively, to detect binding with unprecedented sensitivity. Moreover, we discuss the possibility of combining these novel methods with hyperpolarisation techniques, such as dissolution dynamic nuclear polarisation and para-hydrogen-induced polarisation, to overcome the traditional challenge of many applications of NMR to problems in chemistry and biology: the requirement of transient averaging to achieve sufficient signal-to-noise ratios. This methodological progress permits to lift the requirements in terms of experimental time and materials that are one of the major drawbacks of conventional ligand screening by NMR.
