TL;DR: Stereocomplex assembly of discrete (R)- and (S)-poly(phenyl glycidyl ether-alt-phthalic anhydride)s oligomers revealed that the minimum degree of polymerization required for stereocomplex formation is five.

TL;DR: A retrospect of the experimental development of proton CSA measurement in solid state NMR is presented, from the continuous wave (CW) and multiple pulse sequences for static solid samples, to combined rotation andmultiple pulse spectroscopy (CRAMPS), then to the latest methods including rotary resonance, CSA amplification and R-symmetry pulse sequences under MAS conditions.

TL;DR: In this article, the acidity and host-guest interactions of H-mordenite (H-MOR) zeolites are investigated comprehensively by solid-state NMR spectroscopy and th...

TL;DR: In this paper, a review of dipolar recoupling techniques for fast-to-ultrafast magic-angle spinning (MAS) conditions is presented, where a major focus is the ratio of RF field strength (in frequency) to MAS frequency, ν 1 / ν r, in different pulse sequences.

TL;DR: In this article , the surface structures of γ-Al2O3 and Al(V)-rich Al 2O3 nanosheets were investigated and compared in detail by multinuclear high-field solid-state NMR.
