During evolution, one of the main developments of organisms was the ability to extract oxygen from the environment and carry it to each cell in multicellular organisms in time through metabolism. Life ...

Figure 2: Operando X-ray scattering and spectroscopy studies of SRO films. As may be expected, the low-conductance SRO samples exhibit slower OER kinetics, as shown in Fig. 2b. We remark on two ...
