Synthesis of Carbon Dots via Microwave-Assisted Process: Specific Sensing of Fe(III) and Antibacterial Activity.

Carbon dots synthesized from a renewable and sustainable source of biomass have greater attention in the nanomaterial research field. In the present study, we adopted a facile and green synthesis of carbon dots from bio waste of pumpkin seeds using a one-pot microwave-assisted carbonization method. The synthesized carbon dots exhibit excellent photoluminescence properties with a bright blue emission peak at 399 nm and fluorescence quantum yield was about 9.

Harnessing the ocean's pharmacy: marine bioactive compounds as next-generation therapeutics.

The ocean's vast and diverse ecosystem offers a rich reservoir of bioactive compounds with immense clinical potential. Marine organisms produce structurally unique and biologically active compounds, leading to breakthroughs in therapeutic development. Notable examples include anticancer agents like trabectedin and cytarabine, and the analgesic ziconotide.

Eco-friendly and sustainable process for recovery of sulfate from paper mill mixed salt: Recycling of sulfate for dye fixation process.

Paper mill Electrostatic Precipitator (ESP) ash contains a mixture of alkali metal chloride (34.2 %) and sulfate (84.2 %) which has serious negative effects on the environment and makes it more expensive and constrained to dispose ESP ash.

Electrochemical oxidation with the aerobic pretreatment process for sulfate-rich tannery effluent.

The anaerobic feed of tannery effluent was treated using a new invention of an integrated approach: electrochemical oxidation with aerobic pretreatment, which reduces the chemical oxygen demand (COD) and sulfur/sulfide gas formation. Bacterial consortium was used in the present study isolated from a common effluent treatment plant (CETP). Microbial community analysis of anaerobic feed of tannery effluent (AFTE) was done by next generation sequencing.

An integrated (electro- and bio-oxidation) approach for remediation of industrial wastewater containing azo-dyes: Understanding the degradation mechanism and toxicity assessment.

A hybrid approach for the remediation of recalcitrant dye wastewater is proposed. The chlorine-mediated electrochemical oxidation of real textile effluents and synthetic samples (using Ti/IrO2-RuO2-TiO2 anodes), lead to discoloration by 92% and 89%, respectively, in 100min, without significant mineralization. The remediation was obtained through biodegradation, after removing the residual bio-toxic active chlorine species via sunlight exposition.
