| 1 | Ternary Ni-Co-Fe oxyhydroxide oxygen evolution catalysts:Intrinsic activity trends,electrical conductivity,and electronic band structure显示文摘Nickel-,cobalt-,and iron-based(oxy)hydroxides comprise the most-commonly studied electrocatalysts for the oxygen-evolution reaction(OER)in alkaline solution.A fundamental understanding of composition-structure-activity relationships for mixed-metal Ni-Co and Ni-Co-Fe(oxy)hydroxides is important to guide the design of advanced OER catalysts.Here we use cyclic voltammetry,chronopotentiometry,inductively-coupled plasma-optical emission spectroscopy,and in situ electrical conductivity measurements to characterize the properties and activity of various compositions of Ni-Co-Fe(oxy)hydroxides prepared by cathodic co-electrodeposition.Consistent with previous studies,we find Fe is essential for the mixed-metal(oxy)hydroxides to achieve high OER activity.In the rigorous absence of Fe(achieved by using specially cleaned electrolytes),the most-active Ni-Co(oxy)hydroxide composition has an OER turn-over frequency only twice that ofpure Co(oxy)hydroxide,suggesting minimal synergism between the two metals.The addition of Co to Ni-Fe(oxy)hydroxides shifts the onset of electrical conductivity to lower potentials,but has little effect on the intrinsic OER activity,with the most-active Ni-Co-Fe(oxy)hydroxide having an OER turn-over frequency only -1.5 times that of the Ni-Fe(oxy)hydroxides.The magnitudes of the electrical conductivities are similar for all the compositions measured.Density-functional-theory-calculated projected density of states show a significant contribution of all chemical elements at the valence band edge of the mixed-metal oxyhydroxide electronic structure,demonstrating significant electronic hybridization between the elements.The calculations suggest the involvement of all the elements in modulating the electronic structure at putative Fe-based active sites that are probably located at edges or defects in the two-dimensional oxyhydroxide sheets. | Michaela Burke Stevens Lisa J.

| 17 | 吉西他滨-卡铂方案后续贯性应用紫杉醇-卡铂方案作为晚期卵巢癌一线治疗方案:一项Ⅱ期研究显示文摘Objective. To determine the feasibility and efficacy of sequential gemcitabine- carboplatin followed by paclitaxel- carboplatin in the first- line treatment of advanced epit-helial ovarian cancer, with the response rate as the primary endpoint. Methods. After primary laparotomy, 56 patients with FIGO Stages III- IV disease were given 4 cycles of gemcitabine 1000 mg/m2 d1,8 and carboplatin AUC5 (44 patients) or AUC6 (12 patients) d1 q3wk followed by 4 cycles of paclitaxel 175 mg/m2 d1 and carboplatin AUC5/6 q3wk. Of the tumors, 43 were serous, 6 clear cell, 4 endometrioid, and 3 anaplastic type. Thirty- seven (66.1% ) of the patients were suboptimally debulked. Results. Forty-seven patients were evaluable for response by CA- 125 criteria, and 46 (98% ) responded. Thirty patients (after gemcitabine- carboplatin) and 24 (after paclitaxel- carboplatin) were evaluable for response by CT (RECIST criteria), respectively. After the four gemcitabine- carboplatin cycles, the objective response rate was 83% (6 CR, 19 PR). Following completion of the whole sequential regimen, 7 patients showed a CR and 15 a PR, respectively, giving a response rate of 92% . The median progression- free survival was 12.8 months after a median follow- up of 19 months (range 7- 35 months)- .The median overall survival has not been reached yet. The main toxicity was neutropenia as 139/221 (62.9% ) of the gemcitabine- carboplatin cycles and 92/181 (50.8% ) of the paclitaxel- carboplatin cycles, respectively, were associated with Grades 3- 4 neutropenia. Neutropenia was reported as a serious adverse event in 5.7% of the cycles, and GCSF support was needed in 18.4% of the cycles. Only the gemcitabine- carboplatin cycles were associated with a marked thrombocytopenia (32.1% Grades 3- 4). Of the other side effects, marked allergy occurred in 14/52 (27% ) exposed to paclitaxel. A total of 14 patients discontinued the treatment prematurely: 3 due to lack of efficacy, 1 due to protocol violation, and 10 due to toxicity (4 allergic reactions to paclitaxel, 3 complicated neutropenias, 1 fever, and 2 unspecified toxicities). The mean relative dose intensities were: gemcitabine 84.0% , paclitaxel 85.4% , and carboplatin 96.5% . Of the gemci-tabine- carboplatin cycles and paclitaxel- carboplatin cycles, 32% and 38% were delayed, respectively. Gemcitabine d8 dose had to be omitted in 8% of the cycles. Conclusion. The sequential regimen of gemcitabine- carboplatin followed by paclitaxel- carboplatin is feasible in chemotherapy- naive ovarian cancer. Although its use is associated with a marked neutropenia, the neutropenia is manageable. | Menp J.U. Gréenman S.E. Jalkanen J.T. 朱国栋 | 2006 | 世界核心医学期刊文摘(妇产科学分册)2006，2，9： | 0 |
