Ultrafast spin polarization in a multiferroic manganite BiFe0.5Mn0.5O3 thin film

In this work, we present observations of ultrafast carrier dynamics and spin polarization in a multiferroic manganite BiFe0.5Mn0.5O3 film excited by linearly and circularly polarized femtosecond pulses, respectively. The d-band charge transfer transition is reasonably assigned to Γ3 → Γ5. The transient reflectivity decay on a time scale as fast as only 0.3 ps is consistent with the picture of ultrafast electron-phonon coupling. The ultrafast switching of polarization ellipticity (\u3c 150 fs) originates from a transient coherent spin polarization by optical orientation. The ultrafast spin polarization switching is assigned to the Raman coherence process

Antioxidant phenolics from Broussonetia papyrifera fruits

Fractionation of the EtOH extract from the fruits of Broussonetia papyrifera led to the isolation of 15 phenolic compounds (1–15). Their structures were identified using spectroscopic methods. Among these compounds, 1 and 2 are new and 3–15 were isolated from this plant for the first time. Antioxidant activities of compounds 2–15 against H2O2-induced injury in SY5Y cells and 1,1-diphenyl-2-picrylhydrazyl radical scavenging activities were evaluated
