In the study reported in this manuscript, silver/iron oxide nanocomposites (Ag/Fe2O3) were phytosynthesized using extract of Buddleja lindleyana via a green, economical and eco-friendly strategy. The biosynthesized Ag/Fe2O3 characterized UV-Vis spectrophotometry, FTIR, XRD, TEM, DLS SEM-EDX analyses. particulates showed triangular spherical morphology having sizes between 25 174 nm. FTIR studies on nanoparticles functional groups corresponding to organic metabolites, which reduce stabilize...
High yields of three novel azo disperse dyes based on the diazonium salt sulfonamides-azo-salicylaldehyde were successfully synthesized. These structurally characterized by using spectroscopic techniques, including FTIR, 1H NMR, and MS. The fundamental goal research was to determine optimal dyeing parameters, such as temperature, pH, time, understand behavior dispersed 13–15 during polyester materials. results showed that increasing temperature from 100 130 °C significantly improved dyed...
Dimethine cyanine dye (PTZIS) based on phenothiazine as the core donor and indolium salt acceptor has been synthesized fully characterized. UV-Vis absorption fluorescence properties of PTZIS were studied in different solvents. Absorption spectra revealed a large bathochromic shift intramolecular charge transfer (ICT) band compared with those non-halogenated Also, optical data showed Stokes solvents, indicating great influence geometry emissive excited state. The nonlinear ethanol solution at...
Penconazole (PEN) is a widely used systemic fungicide to treat various fungal diseases in plants but it leaves residues crops and food products causing serious environmental health problems. N-acetylcysteine (NAC) precursor of the antioxidant glutathione body exerts prominent anti-inflammatory effects. The present study aimed explore mechanistic way NAC ameliorate PEN neurotoxicity male rats. Twenty-eight rats were randomly divided into four groups (n = 7) given treated material via oral...
A series of various substituted thiazole-pyrazole hybrids 5, 7, 8, and 9 were synthesized, their chemical structures confirmed by spectral data (infrared, 1H & 13C NMR Mass). The frontier molecular orbital structural energetic properties the targeting explored using DFT/B3LYP methodology. indicated that they had a low energy gap (ΔEH-L), 1.51–2.42 eV, may be sorted as 6 < 7 8 4 3 5. synthesized for activities towards HepG2, MCF-7, HCT-116 in contrast to doxorubicin. newly analogues...
This investigation conducts a side‐by‐side assessment of gear oil augmented with unique hybrid nanoparticle variant: cellulose nanocrystals (CNCs) sourced from biomass and aluminum oxide (Al 2 O 3 ) nanoparticles (NPs). The objective is to ascertain the impact these NPs on lubricative qualities which critical factor for peak functioning durability mechanical systems. composite samples were formulated varying concentrations mixture, consisting 0.25, 0.5, 0.75, 1.0 wt.% CNCs combined Al NPs....
Purpose This study aims to explore a rapid, less expensive, clean and environmentally friendly approach the synthesis of disperse dyes based on 4-substituted benzenesulfonamide derivatives evaluate their uses as colorants for dying printing polyester fabric. Design/methodology/approach The were created by dissolving solution diazonium salt derivative 1 reaction with N’-(2-bromobenzylidene)-2-cyanoacetohydrazide in 25 mL ethanol was added salt. mixture then stirred an ice bath 2 h. Thus,...
This study explores the synthesis and application of terpyridine-based metal complexes (C1-C6) for degradation diclofenac potassium (DCF), a widely used pharmaceutical pollutant. Terpyridine (TPY) ligands their were synthesized characterized using FTIR, UV-Vis, 1H NMR, 13C NMR spectroscopy, mass spectrometry. The novelty this lies in fact that, first time, such structures investigated/explored as potential photocatalysts DCF. demonstrates that target complex compounds exhibit remarkable...

Three novel azo thiazole organic dyes, NA-1–3, have been synthesized and utilized as co-sensitizers in dye-sensitized solar cells (DSSCs). These were designed with a ring π-bridge that mediates between the diazo (–N = N–) functional group carboxylic acid anchoring unit. They possess rod-like molecular structure exhibit strong UV–vis absorption near 600 nm. Co-sensitization studies also conducted ruthenium complex N719. The co-sensitized DSSCs showed enhanced short-circuit open-circuit...
We report on a new organic dye based phenothiazine for DSC application.
A new water-insoluble organic dye, namely, 2-((10-decyl-10H-phenothiazin-3-yl)methylene)malononitrile, was synthesized and fully characterized. It envisioned that photocatalytic decolourization of a dye-containing long chain would pave the way for remediation wastewater containing toxic hydrophobic pollutants. Two commercially available nanoparticles, ZnO TiO2, were selected, their dye from aqueous medium compared. The black UV light irradiation colored samples in presence TiO2 (P25) or...
D-carvone is a natural monoterpene found in abundance the essential oil of aromatic medicinal plants with wide range pharmacological values. However, impact on liver fibrosis remains unclear. This study aimed to evaluate anti-fibrotic potential rat model and clarify possible underlying mechanisms. Liver was induced rats by carbon tetrachloride, CCl4 (2.5 mL/kg, interperitoneally every 72 h for 8 weeks). Oral treatment (50 mg/kg, daily) started 3rd week administration. significantly enhanced...
