窄带隙锡-铅混合钙钛矿太阳电池(PSCs)的效率有望接近Shockley-Queisser极限.然而,易氧化的亚锡离子Sn2+以及载流子传输层/钙钛矿未优化的界面接触会导致严重的界面电荷复合和器件性能下降,这在很大程度上阻碍了锡-铅混合钙钛矿太阳电池的实际应用.本文通过在钙钛矿中掺入少量有机膦酸咔唑分子,成功地制备了无空穴传输层锡-铅混合钙钛矿太阳电池.相对于Pb2+,有机磷酸咔唑分子在晶界处和晶体表面与Sn2+离子有更强的化学配位作用,从而有效抑制Sn2+的氧化,钝化缺陷并抑制非辐射复合.在移除空穴传输层的情况下,此类有机膦酸咔唑分子靶向修饰作用可有效增强内建电场(～100 mV),优化透明导电基底与钙钛矿层的能级排列,从而加速光生电荷分离,促进界面空穴抽取和传输.最终,无空穴传输层的锡-铅混合钙钛矿太阳电池获得最高20.21%的光电转换效率,开路电压高达0.87 v,同时实现了超过2400小时的长期稳定性.

深海氧同位素3阶段(MIS3)是末次冰期中气候转变关键期,也是解剖学意义上的现代人从与其姐妹种群共存到独自发展并扩散至全球的关键演化阶段.中国北方地区横跨亚洲内陆干旱-半干旱区到西北太平洋沿岸,是欧亚大陆东侧人口、文化交流的重要走廊.该区域对于探究MIS3时期全球史前人群群体动态演化、技术与文化发展等具有重要意义.本文通过系统梳理区域内MIS3时期考古学材料,结合已有关键化石和遗传学证据,发现区域内人群经历了从不同人群在边缘区域开始扩散接触,到逐渐深入互动,再经迅速迁徙、渗透、融合,最终在区域内形成稳定群体的三个发展阶段.MIS3早、中期相对暖湿的气候增加了中-高纬度内陆地区地表水的供给,为人群迁徙、扩散提供了关键基础.而进入MIS3中-晚期,随着气候向干冷转化,湖面收缩,到达北方腹地的人群在40 ka左右从遗传学和文化上都相对独立,形成了较为稳定的群体.至MIS3末,随着气候进一步干冷,以细石叶技术为代表的新人群带来新的变化.

世界核心医学期刊文摘（妇产科学分册） 2006年第4期2卷 55-55页

作者： Dixon J.B. Dixon M.E. O'Brien P.E. 党慧敏 australian Centre for Obesity Research and Education Monash Medical School Alfred Hospital Melbourne Vic. 3004 Australia Dr.

Objective: This prospective study sought to examine the outcomes of 79 consecutive first pregnancies ( > 20 weeks of gestation) in women following laparoscopic adjustable gastric banding (LAGB) for severe obesity. METHODS: The 79 women are from a cohort of 1,382 consecutive patients. The prospectively collected data from 79 first pregnancies has been compared with these patients’previous penultimate pregnancies (n = 40), obstetric histories from matched severely obese subjects (n = 79), and community outcomes. RESULTS: The mean maternal weight gain was 9.6 ±9.0 kg, compared with 14.4 ±9.7 kg for the 40 penultimate pregnancies of women in this group (P< .001). There was no difference in birth weights: 3,397 g compared with 3,350 g for preband pregnancies, and these were consistent with normal community birth weights. The incidence of pregnancy-induced hypertension (10%) and gestational diabetes (6.3%) were comparable with community levels (12%and 5.5%) and lower than the obese cohort (38%and 19%) and these patients’penultimate pregnancies (45%and 15%). Monitoring and, if necessary, band adjustments during pregnancy provided more favorable maternal weight outcomes (P = .027). Neonatal outcomes, including stillbirths, preterm deliveries, low birth weight, and high birth weight, were consistent with community values. One woman developed anemia during pregnancy. CONCLUSION: Pregnancy outcomes after LAGB are consistent with general community outcomes rather than outcomes from severely obese women. The adjustability of the LAGB assists in achieving these outcomes. Adjustability is appealing because it allows adaptation to the altered requirements of pregnancy.
