| 1 | Antioxidant and antimutagenic activities of bark extract of Terminalia arjuna显示文摘Objective:The alcoholic extract of stem bark of Terminalia arjuna(ALTA) was screened for antioxidant and antimutagenic(anticlastogenic) activity.Methods:Antioxidant property was determined by l,l,Diphynyl,2-Picryl hydrazyl(DPPH) assay,super oxide radical scavenging activity,lipid peroxidation assay and total polyphenolic content was determined by Folin-Ciocalteau’s reagent.Antimutagenic activity was evaluated using micronucleus test in mice. Results:The ALTA has shown potent antioxidant activity with EC50 of 2.491±0.160,50.110±0.150 & 71.000±0.250 in DPPH assay,superoxide radical scavenging activity and lipid peroxidation assay, which is comparable with ascorbic acid with EC50 of 2.471±0.140,40.500±0.390 and 63.000±0.360 respectively.In micronucleus test,ALTA(100 & 200 mg/kg,p.o.) showed significant reduction in percentage of micronucleus in both polychromatic erythrocytes(PCE) and normochromatie erythrocytes(NCE) and also shown significant reduction in P/N ratio.Conclusions:These results suggested that ALTA possess significant antioxidant and antimutagenic activity. | Gollapalle Lakshminarayana shastry Viswanatha Santosh Kumar Vaidya Ramesh C Nandakumar Krishnadas Srinath Rangappa | 2010 | Asian Pacific Journal of Tropical Medicine2010，3，12： | 9 |
| 2 | Recent Advances in Visible-Light-Driven Photoelectrochemical Water Splitting: Catalyst Nanostructures and Reaction Systems显示文摘Photoelectrochemical(PEC) water splitting using solar energy has attracted great attention for generation of renewable hydrogen with less carbon footprint, while there are enormous challenges that still remain for improving solar energy water splitting efficiency, due to limited light harvesting, energy loss associated to fast recombination of photogenerated charge carriers, as well as electrode degradation. This overview focuses on the recent development about catalyst nanomaterials and nanostructures in different PEC water splitting systems. As photoanode, Au nanoparticle-decorated TiO_2 nanowire electrodes exhibited enhanced photoactivity in both the UV and the visible regions due to surface plasmon resonance of Au and showed the largest photocurrent generation of up to 710 nm. Pt/Cd S/CGSe electrodes were developed as photocathode. With the role of p–n heterojunction, the photoelectrode showed high stability and evolved hydrogen continuously for more than 10 days. Further, in the Z-scheme system(Bi_2S_3/TNA as photoanode and Pt/Si PVC as photocathode at the same time), a self-bias(open-circuit voltage Voc= 0.766 V) was formed between two photoelectrodes, which could facilitate photogenerated charge transfers and enhance the photoelectrochemical performance, and which might provide new hints for PEC water splitting. Meanwhile, the existing problems and prospective solutions have also been reviewed. | Xiaoping Chen Zhixiang Zhang Lina Chi Aathira Krishnadas Nair Wenfeng Shangguan Zheng Jiang | 2016 | Nano-Micro Letters2016，8，1： | 3 |
