Sublethal exposure of emamectin benzoate and thiamethoxam alters the biological parameters and genes expression in Aedes aegypti (Diptera: Culicidae).

Excessive use of agrochemicals results in contamination of water due to runoff or leaching.

Computational insights into phthalimide-core non-fullerene acceptors for next-generation organic solar cells.

Traditional fullerene-based acceptors in organic solar cells (OSCs) suffer from limitations such as poor tunability, narrow absorption spectra, and limited morphological stability, restricting further improvements in device efficiency. To address these challenges, non-fullerene acceptors (NFAs) with tunable energy levels and broad optical absorption have gained increasing attention. In this study, seven novel phthalimide core-based donor-acceptor molecules (BPDM1-BPDM7) are computationally designed by modifying the terminal units of a reference molecule (BPDF).

Overexpression of H-pyrophosphatase () gene improves salinity and drought tolerance in tobacco.

Physiologically, salinity causes osmotic stress due to high solute concentration in soil and disturbs the metabolic and photosynthetic activity of the cells by increasing the toxicity of Na in the cytoplasm. Plant adaptation to salt stress is characterized by cellular ion homeostasis and vacuolar sequestration of toxic ions from cytosol mediated by H-pyrophosphatase (). The gene was cloned under the control of the promoter for yeast transformation and the promoter for tobacco transformation.

Viscous and thermal effects on wave propagation in a micropolar viscothermoelastic medium with impedance considerations.

Wave propagation, a key area in seismology, plays a crucial role in fields such as mineral exploration, hydrocarbon detection, and infrastructure development. Therefore, this study investigates the propagation of plane waves in a homogeneous, isotropic, generalized micropolar viscothermoelastic medium under the influence of viscosity, the hyperbolic two-temperature (HTT) parameter, and impedance boundary conditions. By deriving and reducing the governing equations to two dimensions and transforming them using dimensionless quantities and potential functions, the present model captures the combined effects of thermal, viscous, and micropolar interactions.
