The thoroughly analyzed eight tools determine their greenness. Given its importance in treating hallucinations and delusions produced by Parkinson’s disease psychosis, it is critical have a reliable precise method for identifying pimavanserin (PVS) both pure form pharmaceutical formulations. current used straightforward approach forced...
Role of different strategies in improving active sites N-doped graphene based electrocatalysts for sustainable energy.
Driven by the continuous search for materials with antibacterial and anticancer applications, this study focuses on fabrication of nanocomposite films using chitosan as basis material, addition gadolinium oxide nanoparticles at varying weight percentages (5 10 wt.% Gd 2 O 3 /CS). The were made coprecipitation‐solution cast approach. structural characteristics /CS that formed investigated confirmed a range analytical techniques, including Fourier transform infrared, X‐ray diffraction,...
The purpose of the current investigation was to produce cinammaldehyde-based chalcone derivatives (3a–k) evaluate their potential effectiveness as antioxidant and inhibitory agents versus human Caco-2 cancer cells. findings obtained using DPPH assay showed that compound 3e had highest effective activity with best IC50 value compared other compounds. Moreover, cytotoxic revealed for inhibiting development in contrast all produced derivatives, lowest concentration (32.19 ± 3.92 µM), it also no...
Chitosan (CS) was used as a powerful chelating agent and an excellent template for synthesis of metal oxide nanoparticles (NPs). The CS-MgO nanocomposite film prepared by adding 10%wt MgO relative to CS characterized different techniques. From the FTIR, some main characteristic peaks were shifted due interaction with especially OH NH2 groups. Also, SEM graphs showed clear change in morphological surface CS. Moreover, XRD pattern shows improvement crystallinity incorporation NPs. dielectric...
