Synthesis of quercetin-iron (Fe) complex and its and confirmation towards antibacterial activity.

In this study quercetin-iron complex (QFC) was synthesized, and the structural characterizations such as x-ray diffraction, field emission-scanning electron microscopy, energy-dispersive x-ray and Brunner-Emmitt-Teller adsorption-desorption isotherm analysis revealed the crystallinity state, surface morphology and nature of the adsorbing surface with surface area value. Functional characterizations such as UV-visible spectrometric and Fourier transform infrared analysis collectively indicated the chemical changes that appeared after complex formation in terms of characteristic change in the spectrum and band position, respectively. The antibacterial activity against and has shown a dose-dependent decrease in colony count and achieved significant removal at 15 mg/ml concentration of QFC.

Experimental study of thermal characteristics of ZrO/EG nanofluid for application of heat transfer.

In thermal management system, nanofluids will act as robust elements in future for coolants. Nanofluids have remarkable potential during the heat transfer increase reported by researchers from all over the world. Nanofluids have attracted many researchers, and there have been tremendous advances because of the high thermal characteristics and possible applications in certain areas such as the transport sector, aerospace, medical regions, and microelectronics.

ZrO@chitosan composite for simultaneous photodegradation of three emerging contaminants and antibacterial application.

Emerging contaminants (ECs) are often detected in water bodies due to their prevalent use combined with inefficiency of the conventional wastewater treatment plants for their complete removal. Elimination of ECs using photocatalysis as a tertiary treatment can be a sustainable option for the reuse wastewater. Reported herewith is a photocatalyst, chitosan-based zirconia hybrid composite (ZrOCTS-HC) for the individual/ simultaneous degradation of multiple ECs like Congo red (CR), Methyl orange (MO) and 4-hydroxybenzoic acid (4-HA) under visible light irradiation.

Antioxidant analysis of ultra-fast selectively recovered 4-hydroxy benzoic acid from fruits and vegetable peel waste using graphene oxide based molecularly imprinted composite.

Food processing industries generate 25-30% of fruit and vegetable peel (F&VP) waste of the total produce, which are rich in polyphenolic antioxidants (PA). Sustainable solution for the above waste can be its valorization for the recovery of PA, often used as natural preservative. Present work reports rationally designed graphene oxide-based molecularly imprinted composites (GOMIPs) using ionic liquid 1-allyl-3-octylimidazolium chloride (A) as a green functional monomer for selective recovery of PA 4-Hydroxy benzoic acid (4HA) from F&VP/pomegranate peel (PGP) waste.

Synthesis, characterization and optical property investigation of CdS nanoparticles.

Microwave-assisted routes have attracted much attention for nanoparticle synthesis because of minimal solvent use and rapid, high efficiency and controlled morphology. Cadmium sulphide (CdS) nanoparticles form the line between bulk and molecular states of materials and show variation in their physical and chemical properties. Cadmium sulphate and thiourea were used as precursors during this synthesis.
