“…[22,30,[42][43][44][34][35][36][37][38][39][40][41] For any protective garment using MOF-fabrics, the safety of the fabric itself will be an important concern. While there are only af ew reports regarding MOF safety, [45,46] toxicityi se xpected to depend on MOF crystal size, composition, and stability, with the smallest crystals (< 100 nm) of primary concern.

New materials and chemical knowledge for improved personal protection are among the mostp ressing needs in the international community.R eported attacks using chemical warfare agents(CWAs,) including organophosphate soman (GD) and thioether mustard gas (HD) are driving research in field-deployable catalytic composites for rapid toxin degradation. In this work, we reports imple template-free low temperature synthesis that enables for the first time, ad eployable-structured catalytic metal-organic framework/polymer textile composite "MOF-fabric" showing rapid hydrolysis and oxidationo fm ultiple active chemical warfare agents, GD and HD, respectively,a nd their simulants. Our method yields new zirconium-porphyrin based nanocrystalline PCN-222 MOF-fabrics with adjustable MOF loading and robustm echanical adhesion on low-cost nonwoven polypropylene fibers. Importantly,w ed escribe quantitative kinetic analysisc onfirming that our MOF-fabrics are as effective as or better than analogousM OF powders for agent degradation, especially for oxidation. Faster oxidation using the MOF-fabrics is ascribed to the composite geometry, where active MOF catalysts are uniformly displayed on the MOF-textile enabling better reactant transport and reactive oxidantg eneration.F urthermore, we notet he discovery of visible photo-activation of GD hydrolysis by aM OF-fabric, which is ascribed to oxidation at the active metal node site, significantly increasing the rate over that observed without illumination. These results provide importantn ew insights into the design of future materials and chemical systems to protectm ilitary,f irst-responders, and civilians upon exposure to complex chemical toxins.

“…Here the MIL-100 (Fe) for the incorporation into the PLA matrix is obtained with a green chemistry approach [ 32 ] by microwave (MW) irradiation in a domestic microwave oven. We started from water solutions containing the iron nitrate and the trimesic acid without toxic additives (i.e., HF) that also represents a limit for the scaling up [ 33 ].…”

A microporous carboxylate metal-organic framework MIL-100 Fe was prepared as submicron particles by microwave-assisted hydrothermal synthesis (Fe-MOF-MW). This product was explored, for the first time, for the preparation of polylactic acid (PLA) mixed matrix membranes. The produced MOF was characterised by powder X-ray diffraction (PXRD), environmental scanning electron microscopy (ESEM) as well as by thermogravimetric analysis (TGA) and nitrogen adsorption/desorption. The effect of different Fe-MOF-MW concentrations (0.1 and 0.5 wt%) on the membrane properties and performance were evaluated. These membranes were used in the pervaporation process for the separation of methanol/methyl tert-butyl-ether mixtures at the azeotropic point. The influence of the feed temperature and vacuum pressure on the membrane performance was evaluated and the results were compared with PLA pristine membranes. Moreover, the produced membranes have been characterised in terms of morphology, MOF dispersion in the polymeric membrane matrix, wettability, thickness, mechanical resistance and swelling propensity. The presence of Fe-MOF-MW was found to have a beneficial effect in improving the selectivity of mixed matrix membranes towards methanol at both concentrations. The highest selectivity was obtained for the PLA membranes embedded with 0.5 wt% of Fe-MOF-MW and tested at the temperature of 25 °C and vacuum pressure of 0.09 mbar.

“…The K-βCD-MOFs have good cutting structure, high drug loading capacity and strong inclusion ability, in addition, they are environment-friendly, biocompatible and without side-effects on the human body [Abuçafy et al, 2018;Liu et al, 2017]. Kumar et al [2020] reviewed that MOFs could be widely applied to various areas including catalysis, energy storage, solar cells, air and water purification, gas storage, bioimaging, drug delivery, waste remediation and sensors. So far, MOFs are rarely applied in food, however, K-βCD-MOFs are recognized due to their non-toxicity and unique "food-grade synthesis" based on natural components [Kumar et al, 2020].…”

(J. Tan). technologies for essential oil have raised concern in biology, medicine and food researches in the last few years. As common wall materials for microencapsulation, cyclodextrins (CDs) are a class of cyclic oligosaccharides normally produced from starch under the effect of the enzyme catalytic reaction [Thombre et al., 2013]. CDs are characterized by their amphiphilic structure with hydrophobic inner cavity and hydrophilic outer wall, which could embed guest molecules to form relatively stable complexes [Tian et al., 2020]. They are mainly composed of 6, 7 or 8 glucose units, known as α-, βand γ-CD, respectively [Thombre et al., 2013]. Among them, β-CD is one of the most important members and is derived from 7 d(+)-glucose units linked by α-1,4-glycosidic bonds [Thombre et al., 2013]. Comparing with other CDs, β-CD is the most frequently used CD due to the lowest price and relatively appropriate size cavity. The interest in β-CD regarding its food-related applications has been increasing since it was approved for food uses by FDA [Partanen et al., 2002]. With cavity, β-CD could act as a host and include some molecules as guests to form inclusion complexes by van der Waals and hydrophobic interaction forces, or hydrogen bonds [Deng et al., 2018]. However, the applications of β-CD are limited by its relatively low binding capacity and solubility. Therefore, the metal-organic frameworks (MOFs) with the utilization of the special structure of CDs were developed to solve the above problems. CD-MOFs are network-structure and crystalline porous materials derived from CDs and metal ions or clusters for biomedical applications [Li et al., 2017; Smaldone et al., 2010]. They have high porosity, large surface areas, and ver
