A bead-chain metal-organic framework composite was designed and synthesized by assembling a zeolitic imidazolate framework (ZIF) onto manganese dioxide (MnO) nanowires. The prepared catalyst MnO@ZIF-X (X = 1, 2 and 3) was used to facilitate gatifloxacin (GAT) degradation by using potassium peroxymonopulfate (PMS) as an activator. MnO@ZIF-2 exhibited excellent catalytic performance, achieving 100 % degradation of GAT (10 mg/L) in the presence of PMS (1 mM) in 15 min, and the toxicity of the majority of degradation intermediates decreased.

Bacterial infections and excessive accumulation of wound exudates remain the main obstacles and clinical challenges to the healing of chronic cutaneous wounds. Conventional dressings are commonly used medical materials for acute wound care, but they do not possess the bacterial infection resistance required for chronic wound treatment. Herein, we prepared pure chitosan nanofibrous membranes (C) by electrospinning with poly(ethylene oxide) (PEO) as a sacrificial additive and then loaded with zinc-based metal-organic framework (MOF) as a novel antimicrobial wound dressing.

Porous nanomaterials have shown great promise in many desalination applications. Zeolite nanotubes, featuring abundant but inhomogeneous nanopores on their surface, have been recently synthesized in experiments; however, their capacity for desalination is not yet understood. In this work, we use molecular dynamics simulations to investigate the capability of assembled zeolite nanotube membranes to perform in desalination applications due to their inherent multiscale porous properties.

Multifunctional membranes applied to biomedical materials become attractive to support the biological agents and increase their properties. In this study, biopolymeric fibers based on polycaprolactone (PCL) and pectin (PEC) were reinforced with faujasite zeolite (FAU) for cloxacillin antibiotic (CLX) loading. FAU with a high specific surface area (347 ± 8 m g), high crystallinity and particles with a diameter of up to 100 nm were produced under optimized synthesis conditions (100 °C/4 h).
