Multi-Step Concanavalin A Phase Separation and Early-Stage Nucleation Monitored Via Dynamic and Depolarized Light Scattering

Crystals, Journal Year: 2019, Volume and Issue: 9(12), P. 620 - 620

Protein phase separation and protein liquid cluster formation have been observed analysed in crystallization experiments and, recent years, reported more frequently, especially studies related to membraneless organelles cells. A detailed understanding about the process preceding dense will elucidate what has, so far, poorly understood—despite intracellular crowding being very common processes—and also provide insights into early events of vitro crystallization. In this context, kinetics concanavalin were detail, which applies simultaneous dynamic light scattering depolarized obtain metastable intermediate states between soluble crystalline form. multi-step mechanism was identified for ConA separation, according resultant ACF decay, acquired after an increase concentration agent until a gel final phases observed. The obtained results revealed that is trapped macromolecular network due short-range intermolecular interactions unable transform back non-ergodic solution.

Nickel removal from aqueous solutions using flow-electrode capacitive deionization (Optimization by Response Surface Methodology (RSM))

Water Science & Technology, Journal Year: 2022, Volume and Issue: 86(6), P. 1299 - 1307

Published: Aug. 1, 2022

Abstract Nowadays, wastewater and water treatment with an efficient system for the removal of heavy metals is a serious challenge. Nickel one main metal pollutants that exist in various industries. Several technologies have been developed nickel, including new electrochemical processes. In this experimental study, nickel by flow-electrode capacitative deionization (FCDI) batch-mode investigated. FCDI experiments water-fed concentrations 10, 25, 40 mg/l, input pH 5, 6, 7, sodium chloride content 0, 0.1, 0.2 M flow electrode was investigated to achieve highest rate. Finally, data were analyzed response surface methodology (RSM). Accordingly, best performance achieved at about 6.2, electrolyte NaCl concentration 0.13 M, 10 mg/l.
