Novel biodegradable protonic ionic liquid for the Fischer indole synthesis reaction
Green Chemistry Letters and Reviews, 2016 Novel eco-friendly tetramethylguanidinium propanesulfonic acid trifluoromethylacetate ([TMGHPS][TFA]) ionic liquid was developed as catalyst and medium for the Fischer indole synthesis of a wide variety of hydrazines and ketones. The indole products were

Fungicidal activity of some o-nitrophenyl-hydrazones [PDF]
, 1996 The antimycotic activity of 16 o-nitrophenylhydrazones against strains of Hansenula anomala, Saccharomyces cerevisiae, Candida parapsyliosis, and Cryptococcus albidus was tested. All 16 compounds inhibited growth of the yeast strains.

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Silver‐doped cerium oxide nanoparticles (Ag/CeO2 NPs) were synthesized using Ricinus communis seed extract as a bio‐derived fuel in a solution combustion method. The combustion reaction, carried out at 450°C with AgNO3 and (NH4)2[Ce (NO3)6] as metal precursors, produced CeO2 and Ag/CeO2 NPs.

Chlorella vulgaris biorefineries: sustainable biofuels and high‐value carbon capture
Biofuels, Bioproducts and Biorefining, EarlyView.Abstract Global reliance on fossil fuels has created urgent economic and environmental challenges, yet large‐scale use of algal biomass remains limited by production costs. Industrial scaling is constrained by inefficient harvesting and the technical challenges of processing recalcitrant cell walls.
