Validation of Quick, Easy, Cheap, Effective, Rugged, and Safe (QuEChERS) method was performed for estimation of imidacloprid (IM) and its metabolites in maize leaves, immature kernels, mature kernels, stalk, and soil using liquid chromatograph tandem mass spectrometry, coupled with electrospray ionization. The extraction in different matrices of maize and soil was performed using acetonitrile +0.1% formic acid followed by clean-up with primary secondary amine sorbent and anhydrous magnesium sulfate.

Herein, we report the synthesis of copillar[5]arene-based pyrene Schiff base 1 and its characterization by using 1H, 13C NMR, FT-IR and mass spectrometry. UV-vis absorption, steady-state fluorescence and time-resolved fluorescence are done to elucidate the photophysical behaviors of 1. To understand the electronic structure of 1, density functional theory (DFT) calculations are performed.

Purpose: Due to the extensive use of radiation in various fields, such as food safety, sterilizing surgical materials, and medical diagnostics, it is essential to minimize radiation exposure for both patients and healthcare professionals, even at low doses. To meet this requirement, a composite film has been developed using polyvinyl alcohol (PVA) polymer and nitro blue tetrazolium (NBT) dye to measure low radiation doses effectively.
Methods: Various concentrations of NBT dye (ranging from 0.

Sitobion miscanthi is a wheat aphid species that can damage seriously agricultural production. The effective management of wheat aphids has depended on chemical insecticides. However, their wide application led to severe resistance of wheat aphids to some insecticides, and cytochrome P450 as a detoxifying enzyme plays a crucial role in the insecticide resistance.
