Fabrication of Monarda citriodora essential oil nanoemulsions: characterization and antifungal activity against Penicillium digitatum of kinnow
Kaur, Kiranjot; Tandon, Ritu; Kalia, Anu; Babu, J. Nagendra (Springer, 2023-02-13)Postharvest fungal pathogenic invasions are the major root cause of reduced shelf life of kinnow fruit, thereby contributing to the postharvest losses. Development of eco-friendly alternates are the need of the hour owing ... -
In situ reductive regeneration of zerovalent iron nanoparticles immobilized on cellulose for atom efficient Cr(vi) adsorption
Sharma, Archana Kumari; Kumar, Rabindra; Mittal, Sunil; Hussain, Shamima; Arora, Meenu; Sharma, R.C.; Babu, J. Nagendra (Royal Society of Chemistry, 2015)Zerovalent iron nanoparticles (nZVI) (11.8 - 0.2% w/w) immobilized on microcrystalline cellulose (C-nZVI) were synthesized and studied for Cr(vi) sorption. The material showed good atom economy for Cr(vi) adsorption (562.8 ... -
