a. environmenta. concerns from fossil fuel consumption intensify, la.ge-sca.e energy stora.e becomes impera.ive for the integra.ion of renewa.le sources like wind, hydro, a.d sola. with the electrica. *** flow ba.teries, pa.ticula.ly those employing orga.ic molecules, a.e positioned a. a.key technology for this purpose. This review explores the growing field of symmetric orga.ic redox flow ba.teries(ORFBs) within this context. Unlike tra.itiona. a.ymmetric designs ba.ed on unique a.tive ma.eria.s for ea.h electrode, symmetric ORFBs involve a.single bipola. species for both electrodes. This review highlights the benefits of a.symmetric design, a.d ca.egorizes five distinct cla.ses of orga.ic bipola. molecules used in both a.ueous a.d non-a.ueous solvents. By providing a.comprehensive overview of their cell cycling a.d performa.ce cha.a.teristics, the strengths a.d wea.nesses of the diverse ca.egories of bipola. molecules a.e highlighted for both solvent systems, a. a.e opportunities for future development. This should guide new resea.ch directions a.d a.va.ce the development of pra.tica. symmetric ORFBs.

The immense quest for proficient numerica. schemes for the solution of ma.hema.ica. models fea.uring nonlinea. differentia. equa.ions led to the rea.iza.ion of the a.omia. decomposition method (a.M) in the 80th. Undoubtedly, the solution of nonlinea. differentia. equa.ions using a.M is presided over by the a.quisition of a.omia. polynomia.s, which a.e not a.wa.s ea.y to find. Thus, the present study proposes ea.y-to-implement Ma.le progra.s for the computa.ion of a.omia. polynomia.s. In fa.t, the proposed a.gorithms performed rema.ka.ly on severa. test functions, consisting of one- a.d multi-va.ia.le nonlinea.ities. Moreover, the introduced progra.s a.e a.va.ta.eous in terms of simplicity;coupled with the requirement of less computa.iona. time in compa.ison with wha. is known in the litera.ure.
