  • Solid-state NMR can in principle be used to study calcium environments in biomaterials such as bones/teeth, but43Ca lacks receptivity. Here the authors present an approach to acquire 43Ca data for hydroxyapatite at its natural isotopic abundance, distinguishing between core and surface Ca sites.

  • Defects in metal-organic frameworks impact their structure and properties. Here authors uncover formate defects in MOF-74 that originate from decomposed DMF solvent. NMR shows that the defects partially eliminate open metal sites and lead to a decrease of gas adsorption; the adsorption mechanism of CO2 in defective MOF is also elucidated.

  • Functionalized nanocellulose is a promising drug carrier, however, studying surface functionalization at the atomic scale remains challenging due to spectroscopic methodology limitations. Here, the authors use dynamic nuclear polarization enhanced 13C and 15N solid-state NMR to optimize the drug loading on nanocellulose using aqueous heterogeneous chemistry.
