New magnetic nanocomposites based on hexafrite and keggin-type -type heteropolyanions: Synthesized and characterized for removal of environmental pollutants.

This research paper details the creation of innovative nanocomposites using the sol-gel technique, incorporating polyoxometalates SiWBa to stabilize ceramic particles of strontium ferrite (SrFeO) polymer and Chitosan (CS). The identification and confirmation of the nanocomposites obtained at each stage were carried out through the use of FT-IR, EDX, XRD, and FESEM analyses. To evaluate their ability to remove organic dyes, we analyzed the catalytic activity of these nanocomposites during photocatalytic detoxification procedures.

Preparation of mixed matrix self-cleaning membrane incorporated by Z-scheme heterostructure via robust engineering in terms of dimension for decreasing cake fouling in a cross-flow reactor.

Reducing irreversible fouling in polymer membranes by integrating photocatalytic and membrane processes as the self-cleaning photocatalytic membrane is a promising candidate for improving membrane filtration performance. In this study, mixed matrix photocatalytic membranes were prepared from the combination of different morphologies ZnO-g-CN heterostructure in the polymer matrix by the phase-separation method. To investigate the self-cleaning and performance properties of mixed matrix photocatalytic membranes prepared from different morphologies heterostructures, the photocatalytic membrane reactor with a visible-light source was applied.

Preparation of high-crystalline and non-metal modified g-CN for improving ultrasound-accelerated white-LED-light-driven photocatalytic performances.

As a non-metallic organic semiconductor, graphitic carbon nitride (g-CN) has received much attention due to its unique physicochemical properties. However, the photocatalytic activity of this semiconductor faces challenges due to factors such as low electronic conductivity and limited active sites provided on its surface. The morphology and structure of g-CN, including macro/micro morphology, crystal structure and electronic structure can affect its catalytic activity.

Integrating graphene oxide into layers of PVDF/PVDF@cross-linked sodium alginate/polyamide membrane for efficiently enhancing desalination performances.

The membrane modules of the water treatment system are faced costly damages; thereby executing pre-desalination units based on Nanofiltration (NF) could prevent these suffers, and improve the permeated water flux (PWF) and salt rejection (SR). Hence, we focused on the construction of a novel ternary-layer NF membrane through "electrospinning Polyvinylidene Fluoride (PVDF) (as bottom layer)", "generating middle layer by electrospinning PVDF along with, the implementation cross-linking after electrospraying Sodium Alginate", and "synthesizing Polyamide (as top layer) through interfacial polymerization". More importantly, it anticipated that the Taguchi statistical method can expeditiously optimize the effects of Graphene Oxide nano-sheets (GOns) on water-dependent properties, such as PWF and SR.

Design of a new light curable starch-based hydrogel drug delivery system to improve the release rate of quercetin as a poorly water-soluble drug.

In spite of quercetin advantages, its utilization as a cancer drug is confined due to its very low water solubility and bioavailability. Accordingly, we prepared a biodegradable starch-based hydrogel, using a new technique to control and improve quercetin release and bioavailability. For this purpose, the molecular structure of starch was modified by polyethylene glycol/acrylate and FeO nanoparticles were used to enhance mechanical properties of hydrogel.

Improving photocatalytic activity of the ZnS QDs via lanthanide doping and photosensitizing with GO and g-CN for degradation of an azo dye and bisphenol-A under visible light irradiation.

In this research, insertion of Gd ions (2 wt%) into the crystalline lattice of the ZnS QDs enhanced the photocatalytic activity of the QDs. In addition, the influence of graphene oxide (GO) and graphitic carbon nitride (g-CN) was assessed on the photocatalytic activity of the ZnS QDs through degradation of acid red 14 (AR14) and bisphenol-A (BA) under visible light.

A systematic study on the synergistic effects of MWCNTs and core-shell particles on the physicomechanical properties of epoxy resin.

Here, core-shell impact modifier particles (CSIMPs) and multiwalled carbon nanotubes (MWCNs) were used as reinforcing agents for improving the toughness and tensile properties of epoxy resin. For this purpose, emulsion polymerization technique was exploited to fabricate poly(butyl acrylate-allyl methacrylate) core-poly(methyl methacrylate-glycidyl methacrylate) shell impact modifier particles with an average particle size of 407 nm. It was revealed that using a combination of the prepared CSIMPs and MWCNTs could significantly enhance the toughness and tensile properties of the epoxy resin.

Improvement of microwave absorption properties of polyester coatings using NiFeO, X-doped g-CN (X = S, P, and O), and MTiO (M = Fe, Mg, and Zn) nanofillers.

In recent decades, to reduce electromagnetic pollution, scientists focus on finding new microwave absorbers with effective performance, thin thickness, and broad bandwidth. In this work, the nanoparticles of NiFeO, X-doped g-CN (M = S, P, and O), and MTiO (M = Fe, Mg, and Zn) were successfully synthesized using co-precipitation, specific heat program, and semi-wet sol-gel methods, respectively. The synthesized nanoparticles were utilized as absorption agents and polyester resin as the matrix.

Synthesis of a green bigel using cottonseed oil/cannabis oil/alginate/ferula gum for quercetin release: Synergistic effects for treating infertility in rats.

Although therapeutic effect of quercetin (Quer) was reported on non-alcoholic fatty liver disease (NAFLD), destructive effects have been shown on male fertility due to its pro-oxidative properties. On the other hand, NAFLD impairs germ cells to produce sperm and leads to male infertility. Herein, a biocompatible and green bigel was designed for Quer delivery to prevent infertility induced by NAFLD as the increasing complications.

Enhancing quercetin bioavailability by super paramagnetic starch-based hydrogel grafted with fumaric acid: An in vitro and in vivo study.

Application of Quercetin (Quer) as a natural flavonoid is confined because of limited solubility in water and stability in the body. Herein, we prepared a biodegradable super paramagnetic starch-based hydrogel grafted onto fumaric acid for increasing Quer bioavailability and controlling its release. The molecular structure of starch was modified by using fumaric acid to increase hydrophilicity of hydrogel, and iron oxide nanoparticles is used to strengthen its physical and mechanical properties.
