Nowadays,photovoltaic effect has been widely studied in various ferroelectric materials due to its ap-plications as optoelectronic *** this work,with BiFeO_(3)(BFO)films as the photovoltaic materials,we report the effects of Eu^(3+)doping content on the phase structure,ferroelectric and optical properties of BFO films grown on Ca_(0.96) Ce_(0.04) MnO_(3)/YAlO_(3)(001)*** found that a small doping level of 0.05 could induce a phase change of BFO from tetragonal to rhombohedral,due to the shrinking of the lattice upon Eu^(3+)doping and the breaking of surface terrace structure induced by Ca_(0.96) Ce_(0.04) MnO_(3) *** results in a sharp band gap reduction from 3.30 eV to 2.60 eV,and a decrease in the coercivity of ferroelectric polarization *** on these findings,we investigate the photovoltaic effects of ITO/Eu_(x) Bi_(1-x) FeO_(3)/Ca_(0.96) Ce_(0.04) MnO_(3) vertical *** is found that the short-circuit current density(J_(sc))decreases with increasing Eu^(3+)doping,whereas the open-circuit voltage(V_(oc))first increases to a level of 0.1 V and then decreases with further Eu^(3+)*** could be explained by the combined ef-fect of Schottky-junction and depolarization field on the photovoltaic *** research suggests that a moderate Eu^(3+)doping is helpful for enhancing the photovoltaic effect of BFO thin film devices.

Graphene oxide(GO)with one-atom-thick exhibit remarkable molecule sieving properties,but its low permeance flux renders it difficult to be applied in practice as a high-permeance separation *** this study,we design complex membrane from covalently crosslinked GO,polydopamine(PDA),and 3-aminopropytriethoxysilane(APTES)as building blocks to fabricate the high-permeance GO-based membrane via the vacuum filtration method.A branched crosslinking product(PDA/APTES)working as a clamp grasped the hydrophilic functional groups(hydroxyl,epoxy,carboxyl)on GO for improving the GO membrane *** interlayer structure of the GO membrane was optimized according to the crosslinker concentration,reaction time,initial p H,and temperature for RGO/PDA/APTES(RGPA)in this *** the optimized reaction conditions including the crosslinker concentration of 1.4 m L/L,the temperature of 80°C,the time of 16 h,and the initial p H of 8.5 for RGPA mixture,the interlayer gallery of RGPA membrane was effectively tunes,endowing high flux ranging from 11.98 L m^(-2)h^(-1)to 1823.97 L m^(-2)h^(-1).Besides,the RGPA membrane ensured the high rejections to dye solutions such as methylene blue(MB)(>99%)and congo red(CR)(>90%).Meanwhile,the superior reusable performance of the RGPA membrane was achieved,together with the rejections for MB and CR to 96.32%and 93.1%after 4 cycles,***,the RGPA membrane possessed superior anti-fouling performances for bovine serum albumin(BSA)aqueous solution and excellent stabilities in harsh conditions(p H 3,7 and 11).Grafting the crosslinker onto GO nanosheets exhibits the distinct advantages of achieving the high flux,high rejections to dyes,and superior reusable performance of membranes,posing a great application potential for membrane separation technology in wastewater treatment.

Oxidative stress and cardiomyocyte apoptosis are involved in the pathogenesis of doxorubicin(DOX)-induced cardiotoxicity. Matrine is well-known for its powerful anti-oxidant and anti-apoptotic capacities. Our present study aimed to investigate the effect of matrine on DOX-induced cardiotoxicity and try to unearth the underlying mechanisms. Mice were exposed with DOX to generate DOX-induced cardiotoxicity or normal saline as control. H9 C2 cells were used to verify the effect of matrine in *** injection triggered increased generation of reactive oxygen species(ROS) and excessive cardiomyocyte apoptosis, which were significantly mitigated by matrine. Mechanistically, we found that matrine ameliorated DOX-induced uncoupling protein 2(UCP2) downregulation, and UCP2 inhibition bygenipin could blunt the protective effect of matrine on DOX-induced oxidative stress and cardiomyocyte apoptosis. Besides, 50-AMP-activated protein kinase α2(Ampkα2) deficiency inhibited matrine-mediated UCP2 preservation and abolished the beneficial effect of matrine in mice. Besides, we observed that matrine incubation alleviated DOX-induced H9 C2 cells apoptosis and oxidative stress level via activating AMPKα/UCP2, which were blunted by either AMPKα or UCP2 inhibition with genetic or pharmacological methods. Matrine attenuated oxidative stress and cardiomyocyte apoptosis in DOX-induced cardiotoxicity via maintaining AMPKα/UCP2 pathway, and it might be a promising therapeutic agent for the treatment of DOX-induced cardiotoxicity.

The diurnal course of chlorophyll fluorescence parameter and active oxygen metabolism of flag leaves in PEPC transgenic and untransformed rice Kitaake were studied. The results showed that the photosynthetic rate under high light intensity has been increased by 50% and photoinhibition of photosynthesis in PEPC transgenic was alleviated after the introduction of PEPC gene from maize into rice. It was demonstrated that the increment of photosynthesis in PEPC transgenic was related to the introduction of PEPC gene using specific inhibitor of PEPC. Photoinhibition of photosynthesis in different genotypes exists at noon under natural condition. PEPC transgenic rice exhibited a less decrease in Fv/Fm, a less photoinhibition and a higher efficiency of light energy conversion to chemical energy and lower thermal energy dissipation. These results provided the physiological basis on the mechanism of tolerance to photoinhibition and rice breeding with high photosynthetic efficiency.
