The media effects on the absorption and emission spectral behaviors

This study examines the spectral behavior of three widely used food dyes–Ponceau 4R, Sunset Yellow, and Tartrazine. Despite their structural differences, all three dyes contain…

Data analysis

The reliability and generalizability of results in QSAR modeling heavily depend on the quality and comprehensiveness of the dataset used. Table 1 offers a comprehensive overview of the datasets used for model development and…

Synthesis optimization and structural characterization of ATP–OS

The thermal treatment temperature played a critical role in optimizing the adsorption performance of the ATP–OS composite. Comparative analysis of Cd(II) and Pb(II) removal…

Designing the efficient NiMo/MgO catalyst by tuning Ni-Mo sites

Catalytic performance of NiMo/MgO catalysts with different Ni-Mo ratios

Figure 2 shows the catalytic performance of NiMo/MgO catalysts with different Ni-Mo ratios at 900 °C and…

Characterization of GO and PAN@PRGO composite

The surface morphology of GO and PAN@PRGO was investigated using scanning electron microscopy (SEM). Figure 2 presents SEM images of GO and PAN@PRGO, revealing distinct morphological characteristics….

Characterization by ¹H NMR and FTIR

4-((2′,4′-diflourophenylimino)methyl)phenyl-4′′-pentyloxybenzoate, (5OFB): white (85%); FTIR (cm⁻¹): 1722 (C = O str.), 1600 (C = N str.), 1200 (C–F str.) (Fig. SF1); ¹H NMR (400 MHz, CDCl₃,…

The Parkinson’s disease (PD) is caused by the degeneration of dopamine-producing neurons in the substantia nigra, a region of the midbrain. Dopamine plays an important role in regulating motor functions. It is a critical neurotransmitter whose…
