A novel efficient electrochemical sensor for detecting paracetamol contaminants in polluted water using an active electrode from tungsten oxide nanoplates.

Herein, electrochemical sensing of paracetamol in polluted water was achieved using facile-synthesized tungsten oxide nanoparticles. Ion exchange resin has been used as a sustainable preparation route, while the prepared nanoparticles have been characterized by XRD and SEM analyses. Orthorhombic WO·HO nano-plates have been synthesized a facile preparation method, where the crystal size has been calculated as 25-33 nm, and these results were used to create a 3D model of the prepared WO·HO nano-plates.

Scaling-up production of cost-effective and eco-friendly bio-fertilizer and its application on Barley green fodder via IoT hydroponic system.

Background: Plant-associated microbes (endophytes) have a significant relationship to enhance plant growth and crop productivity by producing proficient bioactive metabolites. Since endophytes promoted plant growth either directly by releasing active metabolites such as phytohormones or indirectly by suppressing the growth of phytopathogens, so, in this work, biomass yield of local endophytic Trichoderma harzianum was maximized at shake-flask scale and scaled up via 7-L Bioflo310 fermenter using continuous exponential fed-batch fermentation mode. Subsequently, the effect of these cells as bio-fertilizer was assessed using two-barley grain genotypes (Russian and Egyptian seeds) via an intelligent hydroponic system based on Internet of Things (IoT).
