| 1 | Impact of photosynthesis and transpiration on nitrogen removal in constructed wetlands显示文摘To determine the impact of photosynthesis and transpiration on nitrogen removal in wetlands,an artificial wetland planted with reeds was constructed to treat highly concentrated domestic wastewater.Under different meteoro-logical and hydraulic conditions,the daily changes of photo-synthesis and transpiration of reeds,as well as nitrogen removal efficiency were measured.It was found that net pho-tosynthesis rate per unit leaf area was maintained on a high level(average 19.0μmol CO_(2)/(m^(2)·s))from 10:00 to 14:00 in July 2004 and reached a peak of 21.1μmol CO2/(m2·s)when Photon Flux Density was high during the day.Meanwhile,TN and NH_(4)^(+)-N removal efficiency rose to 79.6%and 89.6%,respectively-the maximum values observed in the test.Correlation coefficient analysis demonstrated a positive cor-relation among photon flux density,net photosynthetic rate,transpiration rate,and TN and NH_(4)^(+)-N removal efficiency.In contrast,there was a negative correlation between stomatal conductance and TN and NH_(4)^(+)-N removal efficiency.Results suggest that the photosynthesis and transpiration of wetland plants have a great impact on nitrogen removal efficiency of wetlands,which can be enhanced by an increase in the photo-synthesis and transpiration rate.In addition,the efficiency of water usage by reeds and nitrogen removal efficiency could be affected by the water level in wetlands;a higher level boosts nitrogen removal efficiency. | LUO Weiguo WANG Shihe HUANG Juan YAN Lu HUANG Jun | 2007 | Frontiers of Environmental Science & Engineering2007，1，3： | 2 |

| 4 | D-π-D molecular layer electronically bridges the NiO_(x) hole transport layer and the perovskite layer towards high performance photovoltaics显示文摘Nickel oxide (NiO_(x)) has significant cost and stability advantages over poly[bis (4-phenyl)(2,4,6-trimethyl phenyl)amine](PTAA) for inverted p-i-n perovskite solar cells (PSCs),but the poor NiO_(x)/perovskite contact stemming from some reactive species at the interface led to suboptimal device performance.To solve this problem,we take a multiple donor molecule approach,using 3,3’-(4,8-bis(hexylthio)benzo[1,2-b:4,5-b’]dithiophene-2,6-diyl)bis(10-(6-bromohexyl)-10H-phenoxazine)(BDT-POZ) as an example,to modify the NiO_(x)/perovskite interface.The primary goal was to reduce the under-coordinated Ni^(≥3+) cations via electron transfer from the donor molecules to NiO_(x),thus mitigating the detrimental reactions between perovskite and NiO_(x).Equally importantly,the hole extraction at the interface was greatly enhanced after the organic donor modification,since the hydrophobic species atop NiO_(x) not only enabled pinhole-free crystallization of the perovskite but also properly tuned the interfacial energy level alignment.Consequently,the PSCs with NiO_(x)/BDT-POZ HTL achieved a high power conversion efficiency (PCE) up to 20.16%,which compared excellently with that of the non-modified devices (17.83%).This work provides a new strategy to tackle the exacting issues that have so far impeded the development of NiO_(x) based PSCs. | Rongguo Xu Xiuwen Xu Ruixi Luo Yu Li Gaopeng Wang Tongfa Liu Ning Cai Shihe Yang | 2022 | Journal of Energy Chemistry2022，31，4： | 0 |
