In this study, the novel zinc metal-organic frameworks (MOF) nanostructure has been employed, which was developed using an affordable, environmental friendly, efficient and fast method of ultrasound-assisted reverse micelle (UARM). These nanostructures were identified with various techniques such as FT-IR, XRD, BET, SEM, TG-DSC, TEM and EDS. It was found that the Zn-MOF samples have favorable physicochemical properties. The impact of experimental parameters of the UARM method is effective on the resulting properties, such as high surface area of the products that increases the interactions between the Zn-MOF nanostructure and bacteria.Their antibacterial activities were investigated using diffusion methods in agar and also with dilutions of Zn-MOF samples. Antibiotics (tetracycline and ampicillin) and their anti-biofilm effects were evaluated using microplate method. Obtained results revealed that the Zn-MOF nanostructures have high antibacterial properties which, could be due to the nature of the applied Zn-MOF as well as the optimization process. The Zn-MOF nanostructures could be a novel antibacterial material as biocatalyst processes.

“…Zn-MOF/PVA nanofibrous composite synthesized under optimum conditions has a larger surface area (3204 m 2 /g) compared to pure Zn-MOF, chiotsan/PVA composite and Ta-MOF@ Fe 3 O 4 core/shell nanostructures. [49][50][51] The large surface area of Zn-MOF/PVA nanofibrous composite can be attributed to the integration of physicochemical properties of both Zn-MOF and PVA-fibers.…”

Metal organic framework (Zn-MOF)/polyvinyl alcohol (PVA) nanofibrous composite new material has been fabricated using electrospinning and is characterized by a variety of physicochemical analyses, including Fourier transmitting infrared spectroscopy, X-ray powder diffraction (XRD), scanning electron microscopy-energy dispersive spectroscopy, nitrogen adsorption surface, and thermo gravimetric-derivative of thermogravimetry. In this study, the effects of a systematic study including a fractional factorial design were studied for arsenic removal. The results showed that although conventional methods have a high level of arsenic removal, the fractional factor method results in a relatively high level of absorption of arsenic. This high level of arsenic removal allows the potential use of nano adsorbents in various environmental fields. The systematic study developed in this study can be used as a novel protocol to eradicate pollution from different areas, including water, air, and soil.

“…[18,19] Furthermore, the use of fast, efficient, costeffective and eco-friendly microwave and ultrasonic techniques as desirable methods is of great importance. [20,21] Among such novel methods, the microwave processes have received a considerable attention due to the high effect of their parameters on physicochemical properties of the products. In a few studies, microwave techniques have been combined with other novel methods in which physico-chemical properties have been significantly increased compared to those used by microwaves method alone.…”

In this study, Co3O4 nanocatalysts were constructed in environmentally appropriate conditions using controlled, effective, and facile microwave method. The final nanostructures were characterized by SEM, XRD, and TEM analyses. The products had a small size distribution, homogeneous morphology, and crystallographic structures associated with the formation of Co3O4 nanostructures. Moreover, EDS mapping analysis confirmed the existence of Co and O elements in the final structure, and the magnetic properties of the samples were investigated by VSM. The application of this nanostructure in a catalytic process was further examined, and the results suggested that it could be used as a novel candidate for the synthesis of arylidene barbituric and Meldrum,s acid through Knoevenagel condensation of aldehydes by barbituric and Meldrum,s acid in aqueous media. The high yield of these nanocatalysts would be justified by the nature of the nanostructure as well as the experimental procedure developed in this study, which affected the physicochemical features of the products.
