ZIF-8@chitosan (CS)/polyvinylpyrrolidone (PVP) hydrogels (CP x HGZ) were fabricated by in situ growth of metal− organic framework (MOF) crystals on the network of CS/PVP semiinterpenetrating hydrogels. The ZIF-8 crystals were assembled in the channel of hydrogel and coated by networks of hydrogel. Morphology and distribution of the ZIF-8 crystals in CS/PVP hydrogels were modulated by the polymer network of hydrogels. PVP played a key role in guiding the growth of ZIF-8 crystals and preventing aggregation of ZIF-8 crystals in the network of CS/PVP hydrogel. Additionally, the PVP content in hydrogels influencing the adsorption capacity of CP x HGZ for CO 2 was explored. With increasing PVP content in the hydrogels, the equilibrium adsorption of CP x HGZ for CO 2 was increased. Especially, the equilibrium adsorption of CP 10 HGZ for CO 2 was increased by 22%, which was higher than that of the pure ZIF-8 crystals. The results of kinetic simulation, XRD spectra, and FT-IR spectra revealed that the adsorption mechanism of CP x HGZ for CO 2 was mainly chemisorption. The presence of multisites, including the amine groups in CS and PVP as well as metals in ZIF-8, was beneficial for enhancing the adsorption capacity of CP x HGZ for CO 2 .

“…Meanwhile, NO 3− ions induced ZIF-8 to release Zn 2+ ions, and coprecipitation between Zn 2+ and Co 2+ /Ni 2+ formed Ni-Zn-LDHs/Co-Zn-LDHs/Ni-Co-Zn LDHs. [32,33] Yolk-shell structures are created by the partial disintegration of ZIF-8 crystals and the surface development of LDHs, which serve as boxes and shells, respectively. Subsequently, the complexes were treated at high temperature to obtain different metal carbides with hollow structures.…”

Layered double hydroxides (LDHs) with unique layered structure and atomic composition are limited in the field of electromagnetic wave absorption (EMA) due to their poor electrical conductivity and lack of dielectric properties. In this study, the EMA performance and anticorrosion of hollow derived LDH composites are improved by temperature control and composition design using ZIF‐8 as a sacrifice template. Diverse regulation modes result in different mechanisms for EMA. In the temperature control process, chemical reactions tune the composition of the products and construct a refined structure to optimize the LDHs conductivity loss. Additionally, the different phase interfaces generated by the control components optimize the impedance matching and enhance the interfacial polarization. The results show that the prepared NCZ (Ni3ZnC0.7/Co3ZnC@C) has a minimum reflection loss (RLmin) of ‐58.92 dB with a thickness of 2.4 mm and a maximum effective absorption bandwidth (EABmax) of 7.36 GHz with a thickness of 2.4 mm. Finally, due to its special structure and composition, the sample exhibits excellent anticorrosion properties. This work offers essential knowledge for designing engineering materials derived from metal organic framework (MOF) with cutting‐edge components and nanostructures.

Natural and Synthetic Clay Minerals in the Pharmaceutical and Biomedical Fields

et al. 2023

Clay minerals are historically among the most used materials with a wide variety of applications. In pharmaceutical and biomedical fields, their healing properties have always been known and used in pelotherapy and therefore attractive for their potential. In recent decades, the research has therefore focused on the systematic investigation of these properties. This review aims to describe the most relevant and recent uses of clays in the pharmaceutical and biomedical field, especially for drug delivery and tissue engineering purposes. Clay minerals, which are biocompatible and non-toxic materials, can act as carriers for active ingredients while controlling their release and increasing their bioavailability. Moreover, the combination of clays and polymers is useful as it can improve the mechanical and thermal properties of polymers, as well as induce cell adhesion and proliferation. Different types of clays, both of natural (such as montmorillonite and halloysite) and synthetic origin (layered double hydroxides and zeolites), were considered in order to compare them and to assess their advantages and different uses.
