Metallo-Surfactant assisted silver nanoparticles: A new approach for the colorimetric detection of amino acids.

In this study, we report a new class of metallo-surfactant assisted silver nanoparticle produced by reduction process via AgNO solution and extract of Turnera Subulata (TS) in aqueous which act as reducing and metallo-surfactant [Co(ip)(CHNH)](ClO) (ip = imidazo[4,5-f][1,10]phenanthroline) act as stabilizing agent. In this study the silver nanoparticles produced using Turnera Subulata extract has showed yellowish brown color formation and an absorption peak at 421 nm signaling the biosynthesis of silver nanoparticles. The presence of functional groups in the plant extracts were identified by FTIR analysis.

Selective extraction and separation of Li, Co and Mn from leach liquor of discarded lithium ion batteries (LIBs).

Novel route has been developed to selectively extract lithium (Li), cobalt (Co) and manganese (Mn) from the leach liquor of discarded lithium ion batteries (LIBs) containing 1.4 g/L Cu, 1.1 g/L Ni, 11.
