2021年1月1日 · A zeolitic imidazolate framework (ZIF-90) has been synthesized through solvothermal method. The structure was characterized by means of FT-IR spectroscopy, X-ray diffraction, thermogravimetric analysis (TGA), and scanning electron microscopy (SEM)/energy dispersive X-ray spectroscopy (EDS).

Nanocrystals of ZIF-90 have been synthesized at room temperature through a novel procedure and incorporated into PBI-based nano-composite membranes for hydrogen purification. The physical and chemical structures of the ZIF-90 nanoparticles have been examined via multiple advanced instrumental analyses including DLS, XRD, FESEM, NMR and FTIR.

2022年8月1日 · PSM offered enhancement of ZIF-90 properties enabling acidic solutions stability and superior coordination capabilities of P=O and -NH 2 groups towards U (VI)/Th (IV) capture thereby leading to efficient sequestration. ZIFs showed facile desorption by lowering the pH and recyclability for two cycles.

Here, the pH-sensitive material ZIF-90 was synthesized by the liquid-phase diffusion method for loading paclitaxel (PTX), and the targeting peptide (RGD) was prepared by the solid-phase synthesis...

2020年3月1日 · In this paper, to enhance the adsorption capacity of the most important greenhouse gas, carbon dioxide (CO 2), in two types of the most significant and stable of zeolitic imidazolate framework (ZIF) materials, named as ZIF-8 and ZIF-90, a subset of MOF materials, ligand functionalization using various alkali metals is performed through Density f...

The neutral cobaloximes (1−3), double cobaloxime salts (4−6), and their single salts with simple counterions (7−9) were characterized by ¹H and ¹³C NMR spectra, FT-IR spectra, UV-Vis ...
