Coagulation-assisted removal of polystyrene microplastics from aqueous solution using amine-functionalized multi-walled carbon nanotubes with okra extract

Coagulation-assisted removal of polystyrene microplastics from aqueous solution using amine-functionalized multi-walled carbon nanotubes with okra extract

Polystyrene microplastics (PS MPs) are widely distributed in aquatic environments and pose ecological and potential human-health risks. This study investigated the coagulation-assisted removal of PS MPs using MWCNTs@NH2 in combination with okra extract as a natural coagulant aid. A Box–Behnken design was used to evaluate the effects of MWCNTs@NH2 dose (0.2–1 g/L), initial PS concentration (50–400 mg/L),…

Physical Research Laboratory: Sahoo’s PRL Team Reconciles Sodium Theory With Experimental Data

Researchers at the Physical Research Laboratory have performed calculations on sodium (Na) to resolve discrepancies between previous theoretical predictions and experimental data regarding hyperfine structure constants. Their work utilizes relativistic coupled-cluster theory, including triple excitations, to better understand electron correlation and its impact on the nuclear region of the atom.
