“…The amplitude I of each component independently follows the classical CP kinetics model:

I (τ_{italicCP}) = I_{0} [\exp (- τ_{italicCP} ∕ T_{1 ρ}) - \exp (- τ_{italicCP} ∕ T_{italicCP})] ∕ (1 - T_{italicCP} ∕ T_{1 ρ}),

where τ CP is the CP contact time, I 0 the signal amplitude, T CP the CP time constant between proton and phosphorus nuclei, and T 1 ρ the spin-lattice relaxation time of proton in the rotating frame [20,30]. The CP time constant governs the growth of the CP kinetics curve while the spin-lattice relaxation determines the decay [39]. Assuming A is the fast decaying, broad component and B the slow decaying, narrow component, with

T_{italicCP}^{A} < T_{italicCP}^{B}

and

T_{1 ρ}^{A} < T_{1 ρ}^{B}

, the algorithm for the iterative spectral deconvolution and CP kinetics analysis is described as follows.…”

Bone minerals possess two primary hydrogen sources: hydroxide ions in the nanocrystalline core and structural water in the amorphous surface layer. In order to accurately measure their concentrations using hydrogen to phosphorus cross polarization NMR spectroscopy, it is necessary to analyze the dependence of signal intensities on serial contact times, namely, cross polarization kinetics. A reliable protocol is developed to iteratively decompose the severely overlapped spectra and to analyze the cross-polarization kinetics, leading to measurement of hydroxyl and structural water concentrations. Structural water concentration is used to estimate mineral specific surface area and nanocrystal thickness for intact bone.

“…Solid-state NMR has established its position in different fields of science, starting from inorganic materials such as zeolites [205], inorganic polymers [206] and boranephosphane [207] passing through biological [208] and biotechnological systems [209] such as carbohydrates [210], proteins [211], biomembranes [212] and plant cell wall [213], environmental chemistry [214], and ending up with material science, including metal organic frameworks [215], perovskites [216], organic semiconductors [217] and functional nanomaterials [218]. Solid-state NMR spectroscopy, with its diverse techniques and measured nuclei, offers a wide range of valuable information on the geometric and electronic structure of advanced thin-film materials.…”

Solid-state NMR has proven to be a versatile technique for studying the chemical structure, 3D structure and dynamics of all sorts of chemical compounds. In nanotechnology and particularly in thin films, the study of chemical modification, molecular packing, end chain motion, distance determination and solvent-matrix interactions is essential for controlling the final product properties and applications. Despite its atomic-level research capabilities and recent technical advancements, solid-state NMR is still lacking behind other spectroscopic techniques in the field of thin films due to the underestimation of NMR capabilities, availability, great variety of nuclei and pulse sequences, lack of sensitivity for quadrupole nuclei and time-consuming experiments. This article will comprehensively and critically review the work done by solid-state NMR on different types of thin films and the most advanced NMR strategies, which are beyond conventional, and the hardware design used to overcome the technical issues in thin-film research.
