The inhibiting impact of natural aqueous extracts some plants such as curcumin, parsley and cassia bark for the corrosion carbon steel (C-steel) in 0.5 M H2SO4 solution was inspected utilizing techniques galvanostatic potentiodynamic anodic polarization weight loss measurements. Outcomes indicated that percentage inhibition efficiency increases with increasing concentration extract due to its horizontal adsorption on C-steel surface. process is followed by Temkin isotherm. These acted...
In this work, we have successfully synthesized a bimetallic (Zinc and Cobalt) Zeolitic Imidazolate Framework (Zn50Co50-ZIF), class in wider microporous Metal-Organic (MOF) family. The nanostructures maintain both water stability like ZIF-8 (solely Zn containing) charge transfer electronic band the visible optical spectrum as ZIF-67 Co containing). Crystal structure from XRD, high resolution transmission electron microscopy (HRTEM) followed by elemental mapping (EDAX) confirm structural...
Pd nanoparticles were loaded on Co<italic>x</italic>–Mn<sub>(1−x)</sub>-MOF-74. 5 wt% Pd@Co<sub>0.5</sub>–Mn<sub>0.5</sub>-MOF-74 was the most effective catalyst for CO oxidation. The prepared catalysts displayed excellent stability during oxidation without significant decrease in catalytic performance.
Oral delivery of rifampicin through chitosan nanoparticles.
This work focuses on the use of natural parsley oil as a safe, eco-friendly and cost-effective inhibitor for dissolution X80 carbon steel (X80CS) in 0.5 M H
The drug resistance of bacteria is a significant threat to human civilization while the action antibiotics against drug-resistant severely limited owing hydrophobic nature molecules, which unquestionably inhibit its permanency for clinical applications. antibacterial nanomaterials offers major modalities combat bacteria. current work reports use nano–metal-organic frameworks encapsulating molecules enhance activity model and biofilm We have attached rifampicin (RF), well-documented...
The inhibitory impacts of two expired drugs, namely, azithromycin (AZM) and roxithromycin (RXM) towards the corrosion mild steel (MS) in 1.0 M H2SO4 solution were examined exploiting potentiodynamic polarization, electrochemical impedance spectroscopy weight loss techniques. results obtained from various employed techniques indicate that increasing concentration drugs reducing temperature increased inhibition efficiencies. Potentiodynamic polarization indicated AZM RXM acted as mixed-type...
Bacterial infections instigated by antibiotic-resistant bacteria are considered perilous health threats in today's world due to their fast-increasing nature and the fewer availability of new treatment strategies. The properties nanomaterials triggered external stimuli an encouraging technique for remediation antibacterial infectious diseases producing photoinduced reactive oxygen species (ROS). Light-mediated using zinc oxide (ZnO)-based nanohybrids leads field with high interest terms...
Developing a sustainable photocatalyst is crucial to mitigate the foreseeable energy shortage and environmental pollution caused by rapid advancement of global industry. We developed Dy2O3/TiO2 nanoflower (TNF) with hierarchical structure near-ideal anatase crystallite morphology degrade aqueous rhodamine B solution under simulated solar light irradiation. The prepared was well-characterized using powder X-ray diffraction, Fourier transform infrared spectroscopy, transmission electron...
Photocatalysis is realized by the design of a visible-light-active catalyst with robust redox capacity and broad absorption. In this study, series novel Z-scheme CoNiWO4/Ph-gC3N4 photocatalysts are synthesized to improve their property photocatalytic activity toward visible light An intimate stable heterojunction made between cobalt-nickel tungstate (CoNiWO4) phenyl-doped graphitic carbon nitride (Ph-gC3N4), its physicochemical properties studied. The bifunctional all materials were assessed...
The inhibition impacts of two novel synthesized green biosurfactants (B-Surf.), namely, sodium N-dodecyl asparagine (AsS) and arginine (ArS), on the dissolution mild steel alloy (MS-37-2), in aqueous chloride solutions was inspected using various techniques. Increased concentration NaCl solution resulted an increase corrosion rate MS-37-2. Inhibition efficiencies B-Surf. compounds were found to increased with inhibitor concentrations. synergistic action between inhibitors Zn2+, Al3+ Ce4+...
