The present investigation evaluated the effectiveness of chlorella cells in concentrating cu and Ni in their cells and thereby removing the two metals from solution. The removal efficiency of the two metals by free and immobilized algal cells were further studied. (1) Four types of chlorella cells, namely chlorella pyrenoidosa (26) (from carolina Biological Supplies company), chlorella hKBc-1 and-2 (isolated from a polluted stream receiving wastewater from several electroplating factories) and chlorella hKBc-3 (from a clean water pond) were subjected to different concentrations of cu and Ni accordingly. It was revealed that chlorella hKBc-1 was the most tolerant species tocu and Ni as reflected by their highest values of 48 h and 96 h 'highest no effect concentrations' (The highest concentration of the tested substance that does not inhibit the growth rate of the alga: cu 2 and Ni 10 mg/1 at 48 h, cu 2 and Ni 5 at 96 h). This was followed by c. pyrenoidosa (26) and then c. hKBc-2 while c. hKBc-3 had the lowest tolerance to the two metals (cu 0.5 and Ni 2 at 48 h; cu 0.5 and Ni 1 mg/1 at 96 h). (2) It was further revealed that c. hKBc-1 had higher concentration factors and removal efficiencies of Ni (734-963 mg/1, 16.3-18.7%) and c. hKBc-2 had higher concentration factors and removal efficiencies of cu (2316-2839 mg/1, 53.7-66%) when exposed to lower concentrations of cu (0.5,1 and 2 mg/1) and Ni (5, 10 and 13 mg/1). (3) By treating the free and immobilized algal cells (algal cells entrapped in alginate beads) with different concentrations of cu and Ni, it was observed that free cells had higher concentration factors and removal efficiencies when compared with immobilized cells (free cells: cu 1577-3056 mg/1, 24.2-71.4%; Ni 355-849 mg/1, 4.8-18.7%; immobilized cells: cu 453-935 mg/1, 13.9-53.2%; Ni 244-486 mg/1, 3.2-11.9%).

Status and prospects for symmetric organic redox flow batteries

引用

Journal of Energy chemistry 2025年第1期100卷 125-143页

作者： Md Al Raihan c.Adam dyker department of chemistry University of New Brunswick

As environmental concerns from fossil fuel consumption intensify, large-scale energy storage becomes imperative for the integration of renewable sources like wind, hydro, and solar with the electrical *** flow batteries, particularly those employing organic molecules, are positioned as a key technology for this purpose. This review explores the growing field of symmetric organic redox flow batteries(ORFBs) within this context. Unlike traditional asymmetric designs based on unique active materials for each electrode, symmetric ORFBs involve a single bipolar species for both electrodes. This review highlights the benefits of a symmetric design, and categorizes five distinct classes of organic bipolar molecules used in both aqueous and non-aqueous solvents. By providing a comprehensive overview of their cell cycling and performance characteristics, the strengths and weaknesses of the diverse categories of bipolar molecules are highlighted for both solvent systems, as are opportunities for future development. This should guide new research directions and advance the development of practical symmetric ORFBs.

In 1872, George huntington presented his essay “On chorea” to the Meigs and Mason Academy of Medicine and, in doing so, detailed a disease that would later bear his name. huntington's disease(hd) is a genetic, neurodegenerative disease that manifests as the loss of motor control,cognitive impairment,and mood and psychiatric changes in paents.
