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.

Vibrational analysis of oxygen adsorption on the cs and cO coadsorbate precovered Ru(0001)surface was carried out by means of high-resolution electron energy loss *** submonolayer cs coverages on Ru(0001)j an appropriate amount of cO adsorption leads to formation of(2x2)-cs+2cO *** oxygen adsorption on this cs and cO coadsorbate precovered surface results in a remarkable change of high-resolution electron energy loss *** loss peak of c-O stretch mode for 2x2 island species decreases in intensity,which is accompanied by appearance of new bands at about 87 and 240 *** results show that cs adatoms and cO molecules are rearranged upon oxygen adsorption,and are correlated with coexistence of bare surface cO and a mixed phase of cs,cO,and O.

By using a newly implemented high-resolution electron energy loss spectrometer with better resolution,a new loss at a energy near to double energy of the cs-Ru stretching vibration,and its dependence on cs coverage for cs overlayer on Ru(0001)were *** the energy is slightly smaller than the double energy of the cs-Ru vibration(intrinsic loss),overtone excitation must be responsible for this new loss observed,but two-phonon process is not excluded.

The Devonian Woodford Shale in the Anadarko Basin is a highly organic,hydrocarbon source *** values of vitrinite reflectance(R_o)present in the Woodford Shale penetrated by 52 control wells were measured *** vitrinite reflectance values,when plotted against borehole resistivity for the middle member of the Woodford Shale in the wells,display a rarely reported finding that deep resistivity readings decrease as R_o increases when R_o is greater than 0.90%.This phenomenon may be attributed to that aromatic and resin compounds containing conjugated pi bonds generated within source rocks are more electrically conductive than aliphatic *** aromatic and resin fractions were generated more than aliphatic fraction when source rock maturity further increases beyond oil *** finding of the relationship between deep resistivity and R_o may re-investigate the previously found linear relationship between source rock formation and aid to unconventional play exploration.

Aliphatic c–H groups are among the most abundant yet least reactive functional groups in organic molecules. Nature has evolved metalloenzymes such as those of the cytochrome p450 superfamily that efficiently activate individual tertiary（3） and secondary （2） c（sp3）–H bonds in complex molecules with the highest level of regio-and stereoselectivity [1], thus encouraging studies aimed at engineering artificial metalloenzymes for synthetic applications [2].
