    “…A diversity of immunomodulatory agents, including tumor-associated antigens, adjuvants, cytokines and immunomodulators, has been explored for their ability to induce a cascading adaptive immune response. Nanoscale metal-organic frameworks (nMOFs), a class of crystalline-shaped nanomaterials formed by the self-assembly of organic ligands and metal nodes, are attractive for cancer immunotherapy because they feature tunable pore size, high surface area and loading capacity, and intrinsic biodegradability. …”

    “…Oligonucleotides incorporating a central C‐nucleoside with either a rigid or flexible benzaldoxime base moiety have been synthesized, and the hybridization properties of their metallacyclic derivatives have been studied by UV melting experiments. In all cases, the metallated duplexes were less stable than their unmetallated counterparts, and the metallacyclic nucleobases did not show a clear preference for any of the canonical nucleobases as a base‐pairing partner. …”

    “…The expansion of trade has not only increased imports and exports, but also increased metal consumption embodied in them. Based on China's input-output tables from 1997 to 2017, this study uses structural decomposition analysis (SDA) to analyze China's consumption of embodied metal in imports and exports in each sector, and identify their driving factors at the holistic, industrial and sub-sectoral levels. …”
