Electrode electronic structure strongly affects reorganization energy
—
What the study found The study found that the electrode density of states, the distribution of electronic states available in the electrode, plays a central role in governing reorganization energy during interfacial electron transfer. The authors report that this effect outweighs the electrode’s conventionally assumed role. Why the authors say this matters The authors conclude…
Light pulses induce near-perfect valley polarization in graphene
What the study found The study reports that a dual-frequency light pulse can induce highly valley polarized states in graphene, a gapless monolayer material in the Xene family. The authors say the result is a near-perfect valley polarized excitation. Why the authors say this matters The authors conclude that this offers a route to lightwave…
Porphyrin composites improved pentachlorophenol degradation
Zinc porphyrin composites with titanium dioxide and graphene quantum dots achieve 97% pentachlorophenol degradation when combined with hydrogen peroxide pretreatment.
