Fluoride (F) stress is one of the major environmental pollutant, affecting plant growth, development and production, globally. Acquisition of eco-friendly F stress reliever seems to be the major concern these days. Consequently, application of engineered nanomaterials (ENMs) has been increasing to improve agri-economy.

- - A study examined how the rhizobacterium Pantoea conspicua affects the growth of sunflower seedlings under arsenate stress, which typically damages the plants by causing oxidative stress and nutrient leakage.
- - The presence of P. conspicua significantly reduced arsenate levels in the soil (by 75.1%) and enhanced the seedlings' defenses, leading to the production of beneficial compounds like antioxidants and growth hormones.
- - As a result, sunflower seedlings inoculated with P. conspicua showed improved growth rates (up to 127.7% net assimilation and 113.5% relative growth rate) despite being exposed to arsenate, demonstrating the bacterium's ability to support plant health under stress.
This study investigates the magnetohydrodynamic (MHD) flow of ferrofluid along a stretching cylinder. The velocity slip and prescribed surface heat flux boundary conditions are employed on the cylinder surface. Water as conventional base fluid containing nanoparticles of magnetite (Fe3O4) is used.

Using appropriate similarity variables, the partial differential equations are transformed to ordinary (similarity) equations, which are then solved numerically. The effects of various parameters, namely, Deborah numbers [Formula: see text] and [Formula: see text], Prandtl parameter [Formula: see text], Brownian motion [Formula: see text], thermophoresis parameter [Formula: see text] and Lewis number [Formula: see text], on flow and heat transfer are investigated.
